Description
Technical Field
The utility model discloses a circular arc-shaped suture needle, which relates to the technical field of medical appliances and is suitable for suturing tissues in endoscopic surgery.
Background
In the endoscopic surgery, after focal tissues are treated, the focal tissues need to be sutured in time, the suturing efficiency and accuracy in the suturing process are critical, the suturing is critical to the suturing needle, the suturing needle is pierced together by piercing the needle tip and the cutting edge connected with the needle tip in a transitional manner when in use, and the tissues are sutured together, so that the resistance is high in the piercing process, and the problem that the doctor is forced to transition easily to cause the piercing of the normal tissues at the edge is solved. At present, the suture needle has an unsatisfactory structure and is not suitable for being matched with an endoscopic suture instrument.
Disclosure of Invention
The utility model aims at overcoming the defects, and provides the circular arc-shaped suture needle which is matched with a cavity mirror suture device for use, is convenient for connecting suture lines, saves labor when puncturing tissues during suturing the tissues, has small resistance, is convenient to use, and can ensure that the tissues are sutured successfully.
The circular arc suture needle is realized by adopting the following technical scheme.
The circular arc suture needle comprises a circular arc needle body, a needle point is arranged at one end of the circular arc needle body, a needle tail is arranged at the other end of the circular arc needle body, and a suture line connecting hole is arranged at the front end of the needle tail and used for fixedly connecting a suture line. The rear end of the needle tail is provided with a push needle groove I, the rear end of the needle tip is provided with a push needle groove II, and a stop needle clamping groove is arranged close to the push needle groove II and used for clamping the stop needle.
The circular arc needle body is provided with a color ring, and the suture condition of the suture needle can be observed under an endoscope in operation.
The needle tip is arranged in a conical shape or a triangular shape, so that the force and the resistance for puncturing tissues are low.
The circular arc suture needle is used together with the disposable endoscope suture device, the suture thread is fixedly connected in a suture thread connecting hole arranged at one end of the needle tail of the circular arc needle body, and the circular arc suture needle with the thread is arranged in a suture needle holding assembly and a suture needle mounting groove of the disposable endoscope suture device. The movable handle of the disposable endoscope stitching instrument is pulled to drive the rack seat connected with the front end of the stitching steel wire, the rack seat drives the rack, the gear and the gear gasket to drive the connecting piece, the push needle arranged at the front end of the connecting piece passes through the push needle spring tube, the push needle mounting hole of the connecting piece and the push needle gasket under the push needle spring pushing, the push needle is clamped in the push needle groove of the annular stitching needle, the annular stitching needle is pushed to rotate 180 degrees to hook tissues, the movable handle is pulled to complete secondary firing, the push needle pushes the annular stitching needle to continuously rotate 180 degrees, and the annular stitching needle is used for stitching tissues together with stitching threads. And (3) moving an arc-shaped jaw of the suture needle holding assembly, and continuously firing for multiple times to meet the suture requirement of the long incision tissue operation.
The circular arc suture needle has the advantages that:
the circular arc suture needle has reasonable design, is matched with the endoscopic suture device for use, is convenient for connecting suture lines, saves labor when puncturing tissues when suturing the tissues, has small resistance, is convenient for use, and can ensure successful tissue suturing. The suture line connecting hole is arranged at the front end of the needle tail, so that the suture line can be conveniently and fixedly connected. As the circular arc needle body is provided with the color ring, the suture condition of the suture needle can be observed under an endoscope in operation. Because the needle tip is arranged in a conical shape and a triangular shape, the puncture of tissues is labor-saving and has small resistance.
