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

2. 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:

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

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

5. 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:

6. Design #1

7. Design #2

8. Design #3

9. Cost Effectiveness (1-3) Even Pressure Distribution (1-10) Ease of Use by Surgeon (1-10) Feasibility / Practicality of Design (1-10) Meets Design Specs. (1-10) Safety(1-10)Total Design #1 33878534 Design #2 19646430 Design #3 27869840 Current Design 31897634 Design Matrix

10. Elected Design Pressure evenly and effectively distributed Relatively easier to operate Functional with current design parameters Design requirements met Addresses main safety concerns

11. Future Work  Material research  Mechanical design to connect current handle  Prototyping possibilities
