Knot too tight - knot too loose
Develop a prototype system that can provide real-time feedback on suture knot tension applied by veterinary students.
Project Overview
In veterinary surgical training, the ability to tie sutures at the correct tension is a critical skill. Too little tension can lead to wound dehiscence, while excessive tension can cause tissue damage, compromise healing, or even break the suture material.
A particular concern is plastic deformation — the permanent change in the shape or structure of a material after a force exceeds its elastic limit. In the context of suturing, when a student applies excessive force while tying a knot, the suture material or surrounding tissue may undergo plastic deformation, reducing the functional integrity of the closure potentially causing harm to the patient.
A measurement system that can detect suture tension in real time and provide immediate feedback would help students calibrate their technique, preventing damage and promoting optimal healing outcomes. By incorporating objective data into the training process, educators can supplement subjective assessments, standardize expectations, and accelerate skill development.
