Experimental Determination Of Motion Parameters And Path Forces Of Robot-Driven Glenoid Reaming Procedure, Mayank Sharma

Electronic Thesis and Dissertation Repository

Glenoid reaming is one of the most challenging milestones of the total shoulder arthroplasty (TSA) procedure. For a successful TSA, adequate bone resurfacing is required to ensure a well-conformed positioning of the implant onto the native bone.

In this study, a light-weight robot was employed to assert a prescribed thrust-force and reaming depth to mimic clinical practice. Reaming of bone-analogs indicated that specimen density had a linear relationship with reamer velocity and apparent machining stiffness. Human cadaveric bone studies confirmed a linear relationship between specimen density and reamer velocity in both subchondral and cancellous regions of the glenoid. A reaming …

Development And Validation Of A Probe Tube Placement Training Simulator, Robert Koch

Electronic Thesis and Dissertation Repository

For over 90% of individuals with hearing loss, hearing aids are the primary method of treatment. Recent studies have shown that most hearing aids are not personalized properly to patients, resulting in poor hearing outcomes. Poor training methods has been proposed as a possible reason for these findings.

A training simulator was developed consisting of a mannequin head with flexible, anatomically correct ears, and an optical tracking system for tracking the insertion of diagnostic equipment into a 3D printed ear canal. The simulator provides an outlet for trainees to practice their clinical procedures while receiving validated feedback, without the need …

Ultrasound-Augmented Laparoscopy, Uditha Lakmal Jayarathne

Electronic Thesis and Dissertation Repository

Laparoscopic surgery is perhaps the most common minimally invasive procedure for many diseases in the abdomen. Since the laparoscopic camera provides only the surface view of the internal organs, in many procedures, surgeons use laparoscopic ultrasound (LUS) to visualize deep-seated surgical targets. Conventionally, the 2D LUS image is visualized in a display spatially separate from that displays the laparoscopic video. Therefore, reasoning about the geometry of hidden targets requires mentally solving the spatial alignment, and resolving the modality differences, which is cognitively very challenging. Moreover, the mental representation of hidden targets in space acquired through such cognitive medication may be …
