AI Technical Summary

Technical Problem

Traditional thoracoscopic surgery suffers from problems such as tissue damage, operational difficulties, inaccurate control of suture needles, and poor emergency response capabilities during the suturing process.

Method used

A magnetic suture system is used, employing magnetic suture needles and magnetic anchor points. Suturing is performed through a magnetic suture guide, combined with the attraction of a guide sleeve and an electromagnet, to achieve precise guidance and multiple suction and release of the suture, with the magnetic anchor points assisting in suturing.

Benefits of technology

It reduces the risk of bleeding, improves the precision and efficiency of suturing, reduces needle entanglement, simplifies emergency treatment, and optimizes the surgical field of vision and operational flexibility.

Abstract

The invention relates to a magnetic thread system applied to thoracoscopic surgery, which comprises a suture line with a suture needle at the front end, a guide sleeve, a magnetic thread leading device and a magnetic anchor point, the suture needle and the magnetic anchor point are made of magnetic metal materials, and the magnetic anchor point is positioned at the tail end of the suture line. An electromagnet attracted with the suture needle or the magnetic anchor point is arranged at the front end of the magnetic thread leading device, and the guide sleeve is provided with a guide channel leading to the in-vivo suture position from the outside and allowing the magnetic thread leading device and the suture line to pass through. By the adoption of the scheme, the magnetic force line carrying system applied to the thoracoscopic surgery improves the suture effect by changing the needle holding mode and the line holding mode.
