Area of Science:

Minimally Invasive Surgery
Surgical Instrumentation
Laparoscopic Suturing Techniques

Background:

Laparoscopic suturing demands significant expertise, with the needle holder being a critical instrument.
Existing challenges include instrument wobble and difficulty in achieving precise, dexterous movements.

Purpose of the Study:

To develop an improved laparoscopic needle holder designed to minimize wobble.
To enhance suturing accuracy and dexterity for both adult and pediatric patients.
To facilitate seamless knot tying through a narrow tip configuration.

Main Methods:

A prototype laparoscopic needle holder (5mm shaft diameter, short shaft, narrow tip) was developed.
Experienced and novice laparoscopic surgeons performed standardized suturing tasks (needle grasping, suture passing, knot tying).
Participant performance was timed, and a Likert scale questionnaire assessed handling and suturing ease.

Main Results:

The prototype needle holder significantly reduced task completion times for both expert and novice surgeons.
Experts completed needle grasping (Task 1) faster (11.8s vs. 20.8s) and suture tying (Task 2) faster (103.2s vs. 153.2s) with the prototype.
Novice surgeons also demonstrated improved performance times on both tasks using the prototype.

Conclusions:

The prototype laparoscopic needle holder enhances surgical efficiency for both experienced and novice surgeons.
The design effectively addresses wobble and improves dexterity, leading to faster and easier laparoscopic suturing.
This innovation holds potential for improving surgical training and patient outcomes in minimally invasive procedures.
