Veress needle insertion simulation model: A simple new module for advanced surgical skill training.

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.
