Instrument facilitating suture in laparoscopic surgery

Abstract

The invention relates to an instrument facilitating suture in a laparoscopic surgery. The instrument comprises an arc-shaped outer tube, an arc-shaped inner tube, a suture needle, a suture line, a handle, a crack, an arc-shaped bent rod and a joint, wherein the arc-shaped outer tube sleeves the arc-shaped inner tube, the joint is arranged at one end of the arc-shaped outer tube, one end of the arc-shaped inner tube is connected with the handle, the crack is axially arranged on the outer wall of the arc-shaped inner tube, the suture needle is inserted into the arc-shaped inner tube, the tail of the suture needle is connected with the suture line, the suture line is placed in the crack, the arc-shaped bent rod penetrates the arc-shaped inner tube, and the end of the arc-shaped bent rod is provided with an inclined surface abutted to the tail of the suture needle. The instrument is simple in structure, pulling movement of the suture line is realized by the aid of the crack on the arc-shaped inner tube, the suture needle is fixed by the arc-shaped bent rod, a doctor can conveniently, rapidly and accurately find suture positions during suture, the suture needle horizontally enters in suture, suture accuracy is increased, and surgical efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an appliance convenient for suturing in laparoscopic surgery. Background technique [0002] With the continuous development of society, medical equipment is also constantly improving. Among medical devices, surgical instruments are the most frequently used tools. There are many surgical instruments, such as suture needles, open-ended forceps, scissors, scalpels, vascular forceps, surgical forceps, needle-holding forceps, etc. Among them, the instruments used for suturing are the most critical, especially in laparoscopic surgery, suturing is a difficult task operation. The current common practice is to first put the suture needle with thread into the body through the operation channel, and then use the separating forceps and the needle holder to alternately operate (clamp, align) in the body and use the needle holder to hold the appropriate position and angle of the su...
