Project Overview

Design a self-contained, maneuverable endoscopic video camera system that can be set in place and be maintained internally for post-operative viewing. This device would allow a veterinarian to periodically monitor a patient, thus reducing the number of invasive procedures. The client works with small animals at the UW Veterinary Hospital where he currently uses a rigid scope with an attached camera head and a Xenon light source to conduct surgery. At the present time, no device allows for non-invasive post-operative viewing of the abdominal cavity. We are interested in exploring the possibilities of designing an endoscopic camera that can be deftly orientated without compromising the visual capacity of the video camera. Last semester we built a large scale prototype (see photos below), however several modification are needed to make this device fully functional. This semester we will focus on decreasing the size of the current prototype as well as implementing a cleaning mechanism that will clear the camera dome of debris in-vivo.

New magnetically-coupled steering device with plunger system The magnetically induced self-cleansing mechanism is innervated through opposing magnetic poles of the plunger system to drive a rectangular magnet attached to a wire and sponge in order to clean the viewing portion of the dome.
