Development of a collapsible guard component for a novel surgical instrument
The Endoblend is a novel surgical device for use in laparoscopic hysterectomy surgery. Laparoscopic hysterectomy surgery requires that the uterus be removed through a laparoscopic port. To achieve this, the Endoblend liquefies the uterus through the use of cutting blades. The Endoblend has a stem …

DEEP REINFORCEMENT LEARNING FOR ROBOT-ASSISTED SURGICAL TRAINING
… compared to open surgery. Dexterous and complex surgical tools are needed to overcome the limits to operational motion due to smaller incisions. There is also a need to have proficient operation skill in a narrow space. As a result, training time of trainee surgeons is extended. To shorten the …

Bioelectrical strategies for image-guided therapies
… that can rapidly and accurately localize the surgical instrument and its target. We have developed two novel localization methods for the guidance of cardiac ablation and other minimally-invasive therapies. The first method, the Inverse Solution Guidance Algorithm (ISGA), is for the …

Safety Evaluation of Surgical Instruments
… concerns this thesis focuses on the quality of surgical instruments. The current situation is reviewed by considering the regulatory framework and by investigating the quality of newly purchased instruments. A range of test protocols based on British Standards and best practices from industry …

Minimally invasive instrument for in vivo measurement of solid organ mechanical impedance
… be addressed through realistic computer-based surgical simulation systems. To generate a simulation that includes both tactile/haptic and visual feedback, one must know what the material properties of tissue are, so that a finite element or other model can generate the proper predictions for …

Resonance Tracking and Vibration Stabilisation of Ultrasonic Surgical Instruments
Ultrasonic surgical instruments actuated by piezoelectric transducers are usually driven at relatively high power levels to generate high vibration amplitude at the probe, which interact with biological tissues to achieve the desired effects. In operation, the high power level introduces …

Vision Based Surgical Tool Tracking with Robot Kinematics Prior
… scheme, surgeons can execute high-level surgical tasks by commanding instruments controlled by precise robotic devices. Several advantages arise. To name a few: (1) achieved precision is beyond that of human dexterity alone (2) a greater number of kinematic degrees of freedom are possible …

MEDICAL IMAGE BASED PREOPERATIVE ANALYSIS AND INTRAOPERATIVE NAVIGATION
… to help surgeons for medical image analysis and surgical navigation, promoting the vigorous progress of precision medicine. This thesis mainly focuses on preoperative medical image analysis and image-based intraoperative navigation, and corresponding solutions have been proposed to cope with …

Evaluation of the anatomical accuracy of the neuronavigation system “StealthStation” in neurosurgical operations
… planning, real-time intraoperative surgical instrument guidance, and precise localization of intracranial targets. (Bale, Laimer et al. 2006, Georgiopoulos, Ellul et al. 2014) Moreover, in the case of brain biopsies they are combined with miniframe stereotactic devices. As a result, …
