Use Of 3d-Printed Surgical Spoons Compared To Other Cystotomy Methods In Dogs, Davina D'Angelo
Use Of 3d-Printed Surgical Spoons Compared To Other Cystotomy Methods In Dogs, Davina D'Angelo
Animal Science Undergraduate Honors Theses
Bladder stones, also known as uroliths, are not an uncommon condition in domestic dogs. To remove these uroliths, which occur in various sizes, shapes, and compositions, veterinarians will perform a surgical procedure called a cystotomy. A cystotomy consists of creating a small incision into the lumen of the urinary bladder and the utilization of various methods to extract the uroliths. For general veterinary practitioners, the laparoscopic-assisted technique is unavailable. As a result, the methods available for urolith extraction are often limited to flushing the stones out by inserting a urinary catheter through the urinary tract and the use of off-label …

Williams Honors College, Honors Research Projects
The main objective of this project was to create a prosthetic arm for a 15 year old boy named Jaiden Foden. Jaiden was born with only one fully developed limb as a result of a genetic disorder, Hanhart Syndrome II. His right arm becomes a residual limb below the elbow, but has two fingers which act in a “claw-like” movement. Jaiden’s left arm becomes a residual limb above the elbow, and his left leg becomes a residual limb above the knee. The goal of the arm was to increase Jaiden’s overall independence and to help in completing daily tasks, such …
Design And Analysis Of A 3d-Printed, Thermoplastic Elastomer (Tpe) Spring Element For Use In Corrective Hand Orthotics, Kevin Thomas Richardson
Design And Analysis Of A 3d-Printed, Thermoplastic Elastomer (Tpe) Spring Element For Use In Corrective Hand Orthotics, Kevin Thomas Richardson
Theses and Dissertations--Mechanical Engineering
This thesis proposes an algorithm that determine the geometry of 3D-printed, custom-designed spring element bands made of thermoplastic elastomer (TPE) for use in a wearable orthotic device to aid in the physical therapy of a human hand exhibiting spasticity after stroke. Each finger of the hand is modeled as a mechanical system consisting of a triple-rod pendulum with nonlinear stiffness at each joint and forces applied at the attachment point of each flexor muscle. The system is assumed quasi-static, which leads to a torque balance between the flexor tendons in the hand, joint stiffness and the design force applied to …
