Description
Nasal septum stitching instrument Technical Field The invention relates to the technical field of medical instruments, in particular to a nasal septum suture device. Background Nasal septum suturing is a routine procedure after nasal septum deflection correction or nasal surgery, and is mainly used for fixing nasal septum structures, preventing postoperative displacement and promoting wound healing. At present, when the nasal septum is sutured, the needle is clamped by forceps or a needle holder in the nasal cavity of a patient, and because the nasal cavity structure is narrow and deep, the visual condition is poor, the operation difficulty is quite high, and if the operation is improper, mucous membrane tearing or incising is easily caused, new perforation is formed or suture failure is caused. Therefore, the application provides a nasal septum suture device which is convenient for operation. Disclosure of Invention Compared with the existing manual suturing mode through forceps or needle holders, the nasal septum suturing device provided by the invention has the advantages that the double-ended needle shuttles back and forth in the two prongs, the non-suturing area in the nasal cavity is isolated, the visual assembly is not relied on, the blind operation in the true sense is realized, the safety is high, the operation is very convenient, the experience dependence on doctors is greatly reduced, and the efficiency and quality of the nasal septum suturing operation are improved. In order to achieve the above object, the present invention provides the following technical solutions: The nasal septum stitching instrument comprises a needle holding part and a stitching needle which is connected in the needle holding part in a sliding way, wherein the needle holding part comprises two fork heads which can enter a nasal cavity, arc-shaped sliding grooves are arranged in the two fork heads, and the circle centers of the two sliding grooves coincide so that the stitching needle can shuttle back and forth between the two sliding grooves; the suture needle is a double-ended needle with a suture fixed on the middle section, and clamping grooves are formed in the side walls of shafts at two ends of the suture needle; The device also comprises two driving rods, wherein one end of each driving rod is provided with a sliding block which is connected with the sliding groove in a sliding way, and the sliding blocks are provided with clamping heads which can be connected with the clamping grooves; the two fork heads are provided with bulges at opposite ends of the sliding groove and on the surface close to one side of the driving rod, and when the driving rod contacts the bulges, the clamping head is driven to be far away from the clamping groove.
