Summary
A modified Gore suture passer features a self-retracting needle and stabilized grasper, preventing breakage and improving usability in laparoscopic surgery. This innovation enhances instrument reliability and efficiency.
Area of Science:
- Laparoscopic surgery
- Surgical instrumentation
Background:
- The Gore suture passer is a reusable laparoscopic instrument with drawbacks including manual needle retraction and rotational instability.
- These issues can lead to needle tip bending or breakage and difficulty maintaining intracorporeal orientation.
Purpose of the Study:
- To modify the Gore suture passer to address needle retraction and rotational instability issues.
- To enhance the reliability and user-friendliness of the laparoscopic suture passer.
Main Methods:
- A spring was added to the handle for self-retracting needle functionality.
- A screw mechanism was implemented to stabilize the needle and suture grasper within the handle.
Main Results:
- The modified instrument demonstrated self-retracting needle capability and stabilized needle insertion.
- Eighty patient procedures using the modified passer showed no instances of needle breakage or bending.
Conclusions:
- The modifications successfully resolved the original drawbacks of the Gore suture passer.
- The enhanced device is user-friendly, stable, and reduces operative time in laparoscopic procedures.
