Suture traction needle with thread for liver surgical operation

The utility model relates to a suture traction needle with a thread for a liver surgical operation, and belongs to the technical field of medical instruments. The liver suturing device comprises a liver suturing needle, a needle and thread connecting part and a medical grade silica gel line. The suture needle is a stainless steel large-size round needle, the thread is a silica gel thread which has certain elasticity and is consistent with the suture needle in diameter, and the needle and the thread are connected into a whole. During suturing, due to needle and thread integrated design, liver injury caused by a suturing path is relieved; more importantly, in the process of pulling the liver tissue, iatrogenic cutting injury caused to the liver tissue can be obviously relieved through the elastic buffering effect of the silica gel suture line, and liver laceration from deep to shallow caused by excessive pulling can be avoided. The utility model has the advantages of reasonable design and strong practicability,
