AI Technical Summary

Technical Problem

The existing Trocar device has a single function in thoracotomy laparoscopic thyroid surgery and cannot directly manage bleeding within the tunnel. Furthermore, traditional hemostasis methods require the introduction of an electrocautery device, which leads to cross-interference of instruments, limited field of vision, and increased risk of accidental injury.

Method used

A detachable conductive hemostasis trocar device was designed, comprising a conductive ring with adjustable conductive contact area and a visual module. Electrocoagulation hemostasis is achieved through contact between the conductive ring and the tissue, and the visual module expands the field of view and reduces smoke interference.

Benefits of technology

It enables precise hemostasis by adjusting the conductive contact area as needed, reducing the use of additional instruments and improving surgical safety and efficiency.
