Description

Wire cutting pliers Technical Field The utility model relates to a pair of wire cutting pliers, and belongs to the technical field of medical appliances. Background Currently, with the continuous development of medical technology, arthroscopic surgery has become a conventional diagnostic tool for osteoarthritis surgery. In endoscopes of various systems of the whole body, arthroscopic surgery has the most function and the most widely application, such as meniscus suture, rotator cuff injury and the like, and is generally performed after operation on a bone joint, suture is used for suturing tissues in a cavity body, and suture shearing is needed after the suture is performed. The wire cutter in the prior art is heavy in shape, and needs to be threaded from the tail end of the suture, and then the head of the wire cutter is pushed into the knotted tail end of the suture from outside the body along the wire, so that the operation time is increased, and the pain of a patient is increased. Disclosure of utility model The utility model designs and develops a pair of wire cutting pliers, which can be used for carrying out assembly and cutting at any position of a suture, and overcomes the defect that the existing instrument needs to be threaded from the tail end of the suture when cutting the suture. The technical scheme provided by the utility model is as follows: A pair of wire cutting pliers, comprising: a tip tube having a cylindrical structure and having an accommodating space therein; A flat part provided at one end of the tip tube and having an upward opening, such that the flat part forms a receiving groove having an upward opening; the first wire inlet is arranged on the end face of the flat part and is communicated with the accommodating groove; The second wire inlet is arranged on one side of the flat port part and is communicated with the accommodating groove; And the jaw is arranged in the accommodating groove and is rotatably connected with the flat opening part. Preferably, the method further comprises: the connecting rod is coaxially arranged in the tip tube, and one end of the connecting rod is rotatably connected with the jaw; A first operation part, one end of which is rotatably connected with the other end of the connecting rod; And one end of the second operation part is fixedly connected with the other end of the tip tube. Preferably, two lugs are arranged at one end of the jaw at intervals, and the other end of the jaw extends to one side of the second wire inlet to form a jaw part. Preferably, the method further comprises: two flat-mouth connecting holes which are oppositely arranged on the side walls at two sides of the accommodating groove; The two first jaw connecting holes are respectively and oppositely arranged on the two lugs and are positioned at the upper parts of the lugs; The two second jaw connecting holes are respectively and oppositely arranged on the two lugs and are positioned at the lower parts of the lugs. Preferably, a connecting rod hole is formed at one end of the connecting rod, the connecting rod hole is located between the two first connecting holes, and the connecting rod is rotatably connected with the jaw through a connecting rod pin. Preferably, the two second jaw connecting holes and the two flat-mouth connecting holes are riveted through rivets to realize rotary connection. Preferably, the side of the jaw facing the receiving groove has a cutting edge. Preferably, the first wire inlet and the second wire inlet are both in a U-shaped structure. Preferably, the link is connected to the first operating portion by a pivot pin. Preferably, the other ends of the first operation part and the second operation part are both in a circular ring structure and are used for accommodating fingers. The beneficial effects of the utility model are as follows: The utility model provides a pair of novel medical surgical wire cutting pliers, which solves the problems that the existing medical instrument is inconvenient to cut wires and needs to be threaded from the tail end of a suture. The design of front end and side opening can load at the suture line optional position, need not follow terminal loading suture line, and then cut the line, convenient operation improves efficiency. The accommodation space with a large opening can accommodate two sutures at the same time, and the sharp cutting edge can cut two sutures at the same time, so that doctors do not need to cut one by one, and the cutting efficiency is doubled. The binding clip is apart from shearing position certain distance, can remain the reserve line of knot position safe length, effective control end of a thread length, prevent to cut the head and lead to the problem such as knot slackening and end of a thread overlength. And the shearing part uses high-strength and high-hardness metal, so that the conditions of tipping, breakage and the like of a product under the shearing condition of more than 500 times are avoided,
