Abstract：Objective To design the magnetic anchoring tissue clamp and the clamp holder for thoracoscopic surgery based on
magnetic anchoring technique. Methods Based on the magnetic anchoring device of laparoscopic surgery, the heads of the tissue
clamp adopted T-shaped structure, high-wave interface, and a through hole in the tail. The clamp holder with double joint structure
was matched with the through-hole of the tail of the tissue clamp to open the tissue clamp. The hand-held side of the clamp holder
had a serrated lock to position and lock the holder. Results With the application of the tissue clamp and the clamp holder, great
improvements have been made in rigidity, gripping force, tissue damage, manipulation and so on. Conclusion The magnetic
anchored tissue clamp and the clamp holder have the advantages of ingenious design, easy to operate, and can effectively alleviate the
problem of interference between instruments in thoracoscopic surgery, improve the exposure of the operative field, and have certain
clinical application value.
