Modeling and Evaluation of a Large Laparoscopic Grasper With Flexible Fingers, M.Sc. Thesis Sharif University of Technology ; Farahmand , Farzam (Supervisor) ; Kazemzadeh Hannani, Siamak (Co-Advisor)
Abstract
Laparoscopy is a minimally invasive surgical (MIS) procedure specific to the surgical sites within the abdomen. For this surgical method a laparoscope, a camera (endoscope), and a grasping instrument is needed. They all inserted in to the abdomen through openings (5 - 10 mm diameter side port). Currently used grasper heads are small and often with steel material. With respect to these two properties applying large forces that cause damage in the organs is inevitable. The aim of this project is to design a new large laparoscopic grasper head that applies pressure along the length of the lever arms and can take up tissues of large sizes. Based on surveys and estimations SMA, artificial muscles...
