A detachable conductive hemostatic trocar device
By designing a detachable conductive hemostatic trocar device, the problem of existing trocar devices being unable to directly stop bleeding is solved. This achieves the effects of adjustable conductive contact area and expanded field of view, improving the hemostatic effect and safety of thoracotomy laparoscopic thyroid surgery.

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