Abstract
Laparoscopic surgery is a widespread and rapidly growing surgical technique. One of the challenges facing surgeons performing laparoscopic procedures is the retraction of anatomical structures that restrict vision and access to the surgical site. Current solutions to this problem involve opening additional incisions, which causes increased risk and discomfort to the patient. This study proposes a design for a laparoscopic retractor that can be inserted and operated without the need for additional incisions. The anatomical principles relevant to the design are introduced. The inventive problem is investigated and expressed as a problem statement, and the design requirements for the device are listed and explained. The processes of initial concept generation and selection are described, as well as the various stages of design refinement and prototyping performed on the chosen concept. User feedback regarding the alpha prototype of the device is presented. Finally, recommendations are made for future development of the device.
