Laparoscopic Grasping Instrument by Lynn Murray, Becky Jones, Ann Sagstetter and Richard Bamberg

Introduction Laparoscope = thin telescope with light source Minimally invasive surgical technique Operations in abdomen or pelvic cavity Laparoscope inserted 5-10mm canula Side port 5-10mm for grasper Abdomen insufflated: CO 2 or N gas Details of Laparoscopy:

Introduction (cont.) Why Laparoscopy? Minimize blood loss Minimize post-operative pain Expedite recovery time Less risk of complications A much smaller scar

Background Problem at hand: Clips restrain tissue from surgical procedure High pressure, tissue closest to joint Phenomenon: Tissue expelled, trauma caused

Design Objective Grasping instrument designed for internal use Minimize moving parts and safety hazards Equalize pressure across length of clip Device must be <5mm diameter Specifications:
