Available in PDF, EPUB and Kindle. Book excerpt: Femtosecond laser microsurgery has emerged as a remarkable technique for precise ablation of biological systems with minimal damage to their surrounding tissues. The combination of this technique with nonlinear optical imaging provides a means of microscopic visualization to guide such surgery in situ. A clinical endoscope capable of image-guided femtosecond laser microsurgery will provide physicians a means for cellular-level microsurgery with the highest precision. This dissertation focuses the development of a miniaturized fiber-coupled probe for image-guided microsurgery, towards future realization as a clinical endoscope. The first part of the dissertation describes the development of an 18-mm diameter probe. This development includes delivery of femtosecond laser pulses with pulse energy in excess of 1 μJ through air-core photonic bandgap fiber, laser beam scanning by a microelectromechanical system scanning mirror, and development of a new image reconstruction methodology for extracting increased temporal information during Lissajous beam scanning. During testing, the 18-mm probe compares favorably with the state-of-the-art as a microscopic imaging tool and we present the first known demonstration of cellular femtosecond laser microsurgery through an optical fiber. The second part of the dissertation explores further refinement of the design into a streamlined package with 9.6 mm diameter and improved imaging resolution. Study of the optical performance through analytical and computer-aided optical design indicates that simple custom lenses can be designed that require only commercial-grade manufacturing tolerances while still producing a fully aberration-corrected microsurgical endoscope. With the 9.6-mm probe, we demonstrate nonlinear optical imaging, including tissue imaging of intrinsic signals from collagen, using average laser powers 2-3x lower than the current state-of-the-art. We also demonstrate the use of the 9.6-mm probe in conjunction with gold nanoparticles for enhanced imaging and microsurgery through plasmonics. Finally, in the third part of this dissertation, we detail bench-top development of a new clinical application for combined femtosecond laser microsurgery and nonlinear optical imaging: the treatment of scarred vocal folds. We show the utility of femtosecond laser microsurgery for creating sub-epithelial voids in vocal fold tissue that can be useful for enhancing localization of injectable biomaterial treatments. We demonstrate that a single compact fiber laser system can be utilized for both microsurgery and imaging. Furthermore, the proposed clinical technique is shown to be achievable with parameters (e.g., pulse energy, focused spot size) that were found to be attainable with fiber-coupled probes while still achieving ablation speeds practical for clinical use.

Book Synopsis A Magnetic Laser Scanner for Endoscopic Microsurgery by : Alperen Acemoglu
Download or read book A Magnetic Laser Scanner for Endoscopic Microsurgery written by Alperen Acemoglu and published by Springer. This book was released on 2019-07-31 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the design, development, and characterization of a compact magnetic laser scanner for microsurgical applications. In addition, it proposes a laser incision depth controller to be used in soft tissue microsurgeries. The use of laser scanners in soft tissue microsurgery results in high quality ablations with minimal thermal damage to surrounding tissue. However, current scanner technologies for microsurgery are limited to free-beam lasers, which require direct line-of-sight to the surgical site, from outside the patient. Developing compact laser micromanipulation systems is crucial to introducing laser-scanning capabilities in hard-to-reach surgical sites, e.g., vocal cords. In this book, the design and fabrication of a magnetically actuated endoscopic laser scanner have been shown, one that introduces high-speed laser scanning for high quality, non-contact tissue ablations in narrow workspaces. Static and dynamic characterization of the system, its teleoperation through a tablet device, and its control modelling for automated trajectory executions have been shown using a fabricated and assembled prototype. Following this, the book discusses how the laser position and velocity control capabilities of the scanner can be used to design a laser incision depth controller to assist surgeons during operations.

This book was released on 2015 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Femtosecond laser pulses achieve unrivaled microsurgical precision by developing extremely high peak intensity with relatively low total pulse energy. Despite a wide range of clinical advantages and applications that have been identified in bench-top studies, clinical development of femtosecond laser microsurgery outside of ophthalmology has remained in its infancy. The lack of a means to flexibly deliver the high-intensity laser light to areas of interest and guide it with suitable precision has constituted a serious hurdle to further clinical development. In response, this dissertation has detailed my research and development of table-top systems and the fiber-coupled femtosecond laser microsurgery scalpel to treat vocal fold scarring which does not have any reliable treatment in the clinic. This dissertation focuses on laser ablation and nonlinear imaging parameters for creation of sub-epithelial voids in vocal folds and how these parameters varied in scar tissue using animal models. We specifically investigated the differences in tissue architecture and scattering properties, and their relation to ablation thresholds and bubble lifetime. By using nonlinear imaging, we quantified tissue architecture and bubble dynamics. By developing a new method, we measured the ablation threshold below tissue surface while simultaneously extracting the extinction properties of different tissue layers. Also, we performed in-depth analysis using numerical, analytical, and experimental techniques to understand the limitation of maximum imaging depths with third-harmonic generation microscopy in turbid tissues such as vocal folds compared to two-photon autofluorescence microscopies. Our experimental results revealed that maximum imaging depth improved significantly from 140 [mu]m to 420 [mu]m using THG microscopy at 1552 nm excitation wavelength as compared to TPM at 776 nm. The second part of the dissertation explores developing a novel biomaterialdelivery method to inject and localize PEG 30 biomaterial inside sub-epithelial voids created by ultra-short laser pulses within scarred cheek pouch samples. To demonstrate the feasibility of this technique, we developed a semi-automated system to control and monitor the diffusion of the biomaterial inside scarred hamster cheek pouch samples. We observed a back-flow of the injected biomaterial along the point of injection and this condition prevented localization of the biomaterial at the desired locations without creating any void. In contrast to the biomaterial injection outcomes without any voids, the presence of sub-epithelial voids greatly reduced back-flow at the injection site and resulted in a lasting localization of the injected biomaterial at different locations of the tissue. We also performed a follow-up H&E histology and realized that the location and appearance of the biomaterial correlated well with TPAF and SHG in-situ nonlinear images. Finally, in the third part of the dissertation, we developed a piezo-scanned fiber device for high-speed ultrafast laser microsurgery, with an overall diameter of 5 mm. While the diameter of the scalpel is now half of our latest probe, its resolution has been also improved by 10% in both lateral and axial directions. The use of a high repetition rate fiber laser, delivering 300,000 pulses per second, and utilizing a sub-frame rate Lissajous scanning approach provided high ablation speeds suitable for clinical use. As shown by the uniform ablation of gold samples, an ablation FOV of 150 [mu]m x 150 [mu]m could be achieved within only 50 ms. With such ablation speeds, drilling into a cheek pouch tissue was possible using pulse energies of 200 nJ (3.2 J/cm2). With these speeds the surgeon could potentially move the surgery probe at speeds near 4 mm/s laterally in one direction while continuously removing a 150 [mu]m wide tissue layer.

Book Synopsis Development of a Feedback Control System for Femtosecond Pulsed Laser Surgery by : Ruby K. Gill
Download or read book Development of a Feedback Control System for Femtosecond Pulsed Laser Surgery written by Ruby K. Gill and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing interest in ultra-short pulsed laser surgery combined with a feedback control mechanism for high-precision cutting with minimal collateral damage. Compared to conventional nanosecond lasers, ultra-short pulsed lasers do not deposit as much heat in the sample and therefore do not cause adverse thermal effects such as fractures. For implementation in the clinic, a real-time feedback control system will ensure that the laser is incident on the targeted tissue and does not cause damage to surrounding tissues. There are a variety of optical spectroscopy techniques that have the potential to be successfully incorporated into a feedback control mechanism for laser surgery. The technique investigated in this dissertation is the basic atomic spectroscopy technique, laser induced breakdown spectroscopy (LIBS), since it would allow the use of the same laser that is being used for ablation. The main objective of this work is to investigate how the LIBS signal changes under different experimental conditions with implications towards using this technique as a feedback control system for ultra-short pulsed laser surgery applications. To achieve this objective, this dissertation work was split into three aims: characterizing the LIBS signal as a function of various experimental parameters, evaluating the effect of repetition rate on the LIBS signal, and assessing whether LIBS could be used to distinguish between tumor bone and normal bone. LIBS signals are produced when the laser fluence exceeds a given threshold for molecular breakdown of a sample. Immediately following, bound electrons are ionized and a plasma plume is formed. When the laser excitation source is turned off, the free electrons recombine with positively charged ions and atoms. Once these ions and atoms relax from their excited states, they emit characteristic atomic lines that can be detected. The ejected or evaporated material leads to crater formation on the sample. To test the first aim, the LIBS intensity dependence on different parameters such as sample, laser energy, scanning speed, and depth of focus was characterized. The LIBS spectra were acquired using a custom-built upright microscope to tightly focus a femtosecond pulsed laser with an objective lens on to bone and soft tissue. The LIBS bone and soft tissue spectra showed distinct differences indicating that they can be successfully distinguished from one another. The bone LIBS spectrum showed several strong calcium peaks and a sodium peak in the spectral region we analyzed. The soft tissue LIBS spectrum showed a single distinct sodium peak near 590 nm. The LIBS signal for bone was also characterized as a function of the following excitation parameters: laser energy, depth of focus, and number of pulses per focal volume. A linear increase in the LIBS intensity as a function of the laser energy from 25 to 75 [mu]J was observed. In addition, we showed that moving the beam out of focus and the presence of overlapping pulses on the same focal area leads to a decrease in LIBS intensity due to changes in focal spot size. The LIBS intensity varied by an order of magnitude when the laser was moved out of focus. These results indicated that a potential feedback system for laser surgery should not be directly dependent on LIBS intensity. The feedback control algorithm should instead rely on a ratio algorithm that compares two or more unique spectral peaks. We compared the ratio between the calcium peak intensity at 612 nm to the sodium peak intensity at 589 nm. Under conditions where the repetition rate is constant at 1 kHz and there is a minimal temperature rise, the ratio between the calcium to sodium peak to be constant over a depth of approximately 1 mm. For practical considerations in the clinic, it is not enough to have a real-time feedback control system for laser surgery. The femtosecond laser cutting speed needs to be increased to a level that is comparable to or faster than the mechanical tools currently used for hard tissue surgeries. For this reason, the second aim of the dissertation work focuses on evaluating the effect of increasing laser repetition rate on ablation width, sample temperature, and LIBS signal of bone. SEM images were acquired to quantify the morphology of the ablated volume and LIBS was performed to characterize changes in signal intensity and background. For the first time, experimentally measured temperature distributions of bone irradiated with femtosecond lasers at repetition rates below and above carbonization conditions are shown. At repetition rates where carbonization occurs, the sample temperature increases to a level that is well above the threshold for irreversible cellular damage. At these carbonizing repetition rates, we also observed a change in the LIBS spectrum. At repetition rates above carbonization, the calcium to sodium peak ratio for bone decreases to a value that is similar to soft tissue. Under these conditions, the bone would be misclassified as soft tissue using LIBS. These results highlight the importance of the need for careful selection of the repetition rate for a femtosecond laser surgery procedure to minimize the extent of thermal damage to surrounding tissues and prevent misclassification of tissue by LIBS analysis. The third aim centers on assessing whether LIBS can also be used to distinguish between tumor and normal bone with the potential to be used to identify tumor margins in real-time. To test the third aim, preliminary LIBS measurements were performed on a primary bone tumor and matched normal bone sample. Analysis of the LIBS spectra showed a change in the magnesium peak intensity relative to the calcium peak intensity between primary bone tumor and normal bone. These results show the potential for LIBS to be used for identifying tumor margins in real-time to ensure complete removal of tumor tissue. This dissertation demonstrates that LIBS shows promising potential to be used as a real-time feedback control system for ultra-short pulsed laser surgery procedures. The long-term vision for this work is to develop a fully integrated feedback control system for ultra-short pulsed laser ablation surgery to have high precision cutting with minimal damage to surrounding tissues. The feedback control system should divert the laser beam when it is incident on surrounding tissues based on their spectral signature. This would allow for high precision cutting with minimal damage to surrounding tissues. In the proposed case of spinal surgery, the feedback control system would ensure that the laser surgical tool only cuts bone and prevents damage to the spinal nerve.

Download or read book Femtosecond Laser Beam Propagation Through Corneal Tissue written by William R. Calhoun (III) and published by . This book was released on 2015 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most recent advancements in laser technology is the development of ultrashort pulsed femtosecond lasers (FSLs). FSLs are improving many fields due to their unique extreme precision, low energy and ablation characteristics. In the area of laser medicine, ophthalmic surgeries have seen very promising developments. Some of the most commonly performed surgical operations in the world, including laser-assisted in-situ keratomileusis (LASIK), lens replacement (cataract surgery), and keratoplasty (cornea transplant), now employ FSLs for their unique abilities that lead to improved clinical outcome and patient satisfaction. The application of FSLs in medical therapeutics is a recent development, and although they offer many benefits, FSLs also stimulate nonlinear optical effects (NOEs), many of which were insignificant with previously developed lasers. NOEs can change the laser characteristics during propagation through a medium, which can subsequently introduce unique safety concerns for the surrounding tissues. Traditional approaches for characterizing optical effects, laser performance, safety and efficacy do not properly account for NOEs, and there remains a lack of data that describe NOEs in clinically relevant procedures and tissues. As FSL technology continues to expand towards new applications, FSL induced NOEs need to be better understood in order to ensure safety as FSL medical devices and applications continue to evolve at a rapid pace. In order to improve the understanding of FSL-tissue interactions related to NOEs stimulated during laser beam propagation though corneal tissue, research investigations were conducted to evaluate corneal optical properties and determine how corneal tissue properties including corneal layer, collagen orientation and collagen crosslinking, and laser parameters including pulse energy, repetition rate and numerical aperture affect second and third-harmonic generation (HG) intensity, duration and efficiency. The results of these studies revealed that all laser parameters and tissue properties had a substantial influence on HG. The dynamic relationship between optical breakdown and HG was responsible for many observed changes in HG metrics. The results also demonstrated that the new generation of therapeutic FSLs has the potential to generate hazardous effects if not carefully controlled. Finally, recommendations are made to optimize current and guide future FSL applications.

This book was released on 2015 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Femtosecond pulse lasers have proven to be versatile for micro-scale ablation of a variety of materials with high quality machining due to minimal residual stress, heat affected zone, and melting. In addition, femtosecond laser is one of the non-cleanroom techniques that does not require masking, chemical reagents, and multiple steps. This simple and convenient micromachining technique enables machining of various materials in 3-dimensional geometry. However, some factors such as optical scattering, beam shape, and debris accumulation hinder the high quality of ablation. In this dissertation, femtosecond laser was employed for the micromachining of electrospun nanofibers and metals. Optimization of a process for the high quality femtosecond laser machining was investigated. Femtosecond laser and electrospun poly(e-caprolactone) (PCL) nanofibers mesh interaction was analyzed by optical property measurements and the optical absorption and scattering coefficients were estimated. The specific energy required for ablating a unit volume of pure PCL nanofibers and polydimethylsiloxane-poly(e-caprolactone) (PDMS-PCL) core-shell nanofibers was measured. Material inherent optical properties including the ablation threshold fluence and the incubation coefficient of PDMS and PCL were estimated. Circular grooves were fabricated on aluminum, stainless steel 316, and Stellite 6 and circular disks were successfully machined from a thick section of Stellite. The tapered cross-section was detected from the Stellite disk and the tapering was minimized by varying pulse energy during ablation process. Moreover, a novel debris removal technique based on DC-dielectrophoresis (DEP) force was used to machine the linear and circular grooves on aluminum and the ablation depth and precision were compared with the gas jet debris removal technique.

Book excerpt: This book presents new research related to femtosecond laser ablation, coherent control, electronic and thermal processes, coloring, nanoscale heat transfer, and corneal refractive surgery. With laser-pulse durations of one quadrillionth of a second, femtosecond lasers are poised to change the way research is done in a variety of disciplines in science, engineering and medicine. The ability to remove material with minimal collateral damage may be the most striking feature that has not been matched by any other material processing technologies. With the processing power carried by each pulse entering pettawatts (1015 W) in less than 100 femtoseconds, femtosecond lasers can remove virtually any type of material in a few picoseconds while confining the process zone to within tens of nanometers. The result is clean cuts, strong welds, and precision destruction of small targets such as cancer cells with no injury to surrounding materials.
