The physicians performing colonoscopy are at risk due to the occupational overuse injuries and exposure to infectious splatters from the patient's anus. The objective of this thesis is to develop medical equipment to make the colonoscopy procedure safer and more comfortable for performing physicians. To understand the problem well, the colonoscopy procedure was directly observed. Additionally, physicians were questioned to better comprehend safety issues associated with the procedure. Subsequently, two devices were developed in an attempt to make the procedure safer for the physicians[1]. The Control Head Holder (CHH) holds the control head of the colonoscopy equipment, which provides the physician with less fatigue during the procedure. A splatter shield was also developed to mitigate the physician's exposure to bodily fluids. The splatter shield provides added advantage of a holder for the insertion tube of the colonoscope which grants the physician the extra freedom to perform activities that may require two hands. A proof of concept prototype of the CHH and the shield with the Tube Holder (TH) was fabricated as per the requirements. The shield was then subjected to drop test and drop ball test to validate the desired deliverables. The force required to initiate slipping from the TH was determined using a force sensor. The CHH was checked for fatigue reduction with medical students through surface Electromyography (sEMG). The equipment was also evaluated by a group of students and experts who performed the procedure on the Active Colonoscopy Training Model (ACTM) simulator while monitoring space preservation, ease of use, clarity, degree of freedom and overall rating. The results of this research suggest that the implementation of the CHH is a positive value addition for the comfort of physicians performing colonoscopy. However, further research is necessary to enhance the capability of the developed equipment for serving physicians better.
