Basic training model for supermicrosurgery: a novel practice card model

Area of Science:

• Surgical Innovation
• Microsurgery Training

Background:

• Supermicrosurgery involves anastomosing vessels 0.5 mm or smaller, posing significant technical challenges compared to larger vessels.
• Acquiring proficiency in supermicrosurgery requires dedicated practice, particularly for suturing and vessel anastomosis.
• Existing training methods may not adequately prepare surgeons for the intricacies of supermicrosurgical procedures.

Purpose of the Study:

• To introduce a novel, accessible practice card model for developing fundamental supermicrosurgical techniques.
• To provide a reproducible and cost-effective training solution for microsurgeons.
• To facilitate repeated practice of supermicrosurgical suturing and anastomosing skills.

Main Methods:

• Development of a practice card using small-caliber silicone tubes (0.3, 0.5, 0.7 mm diameter) with 0.05 mm wall thickness, mounted on paper.
• Utilizing the practice card with personal desk stereomicrosopes and operating microscopes for training.
• Describing basic training protocols for high-magnification use of the practice card.

Main Results:

• The practice card effectively simulates small-caliber vessels for supermicrosurgical training.
• Surgeons can practice and warm-up supermicrosurgical suturing and anastomosing techniques using the model.
• The system allows for repeated practice in various settings, including offices and operating rooms.

Conclusions:

• The developed practice card is a valuable, simple system for acquiring and refining basic supermicrosurgical techniques.
• This training model enhances microsurgeons' ability to perform delicate procedures, potentially benefiting multiple surgical specialties.
• Consistent practice with this tool can lead to improved supermicrosurgical proficiency and patient outcomes.
