Area of Science:

• Surgical Simulation
• Medical Device Development
• Robotic Surgery

Background:

• Robotic-assisted complete mesocolic excision (CME) presents anatomical challenges for surgical training.
• Simulation phantoms are crucial for learning advanced surgical procedures.
• No phantoms specifically for robotic CME were previously available.

Purpose of the Study:

• To develop an anatomically accurate phantom for robotic-assisted CME.
• To create a tool for both training and competency assessment.
• To enable simulation in a clinical setting using existing robotic systems.

Main Methods:

• Utilized established pathology and surgical assessment tools for CME.
• Incorporated 3D printing of patient-specific anatomical models.
• Iteratively tested and refined prototypes based on expert surgeon feedback.

Main Results:

• Successfully integrated 35/48 procedure-specific items and all pathology evaluation items.
• Developed a novel method for assessing mesocolon integrity using fluorophores and UV light.
• Created a durable, easy-to-store silicone phantom compatible with clinical robotic systems.

Conclusions:

• The developed phantom is suitable for training and competency assessment in robotic-assisted CME.
• This innovation addresses a critical need for realistic simulation in advanced robotic surgery.
• The phantom facilitates safe and effective skill acquisition for surgeons.
