Development of a laparoscopic sigmoidectomy simulator: Sigmaster.

Area of Science:

• Surgical Simulation and Medical Device Development

Background:

• Laparoscopic sigmoidectomy requires specialized training due to complex anatomical structures.
• Existing simulators may not fully replicate the tactile and visual fidelity needed for effective training.

Purpose of the Study:

• To develop and evaluate Sigmaster, a novel simulator for laparoscopic sigmoidectomy.
• To create a training device that accurately reproduces sigmoid colon anatomy and allows for realistic surgical techniques.

Main Methods:

• Designed Sigmaster using dry polyester fibers to mimic anatomical layers, including blood vessels, nerves, and intestinal tracts.
• Engineered controlled adhesive strength for realistic layer separation during simulated surgery.
• Validated the simulator by comparing simulated sigmoidectomy with actual surgical procedures.

Main Results:

• Sigmaster successfully reproduces the layered anatomical structure of the sigmoid colon.
• The simulator's conductivity enables the use of energy devices during training.
• Realistic peeling techniques are achievable due to controlled layer adhesion.
• Simulated sigmoidectomy using Sigmaster closely mirrors the actual surgical process.

Conclusions:

• Sigmaster provides a realistic and effective training platform for laparoscopic sigmoidectomy.
• The simulator enhances surgical training by replicating key anatomical features and procedural steps.
• Sigmaster has the potential to improve surgeon proficiency and patient outcomes in sigmoid colectomy.
