Area of Science:

Surgical Education
Medical Device Simulation
Minimally Invasive Surgery Training

Background:

Veress needle (VN) insertion requires tactile feedback for effective training.
Observation alone is insufficient for mastering VN insertion skills.
A need exists for a realistic and reproducible training model.

Purpose of the Study:

To develop a novel training model for Veress needle insertion.
To evaluate the validity of this model in simulating real surgical experiences.
To assess its utility for surgical skill acquisition.

Main Methods:

A three-layer synthetic model mimicking abdominal wall layers was created.
Experienced surgeons and residents practiced VN insertion on the model.
Participant feedback was collected via comments and questionnaires.

Main Results:

The model accurately simulated surgical shape, structure, and tactile feedback.
86% of participants found the force feedback comparable to real surgery.
93% considered the model a valuable pre-patient training resource.

Conclusions:

The developed Veress needle insertion training model offers a valuable opportunity to practice a critical surgical skill.
The model is simple, reproducible, and provides a realistic simulation of surgery.
It serves as an effective tool for enhancing surgical proficiency.
