Description

Wire passing forceps for orthopedic operation

Technical Field

The utility model relates to a line passing forceps for orthopedic surgery, which belongs to the technical field of orthopedic surgery instruments.

Background

Bone surgery, especially fracture surgery, meets less bone fragments and falls off, often also needs to be tied up with steel wires or wires besides being fixed with screws, and simple surface tying up, because of human activity after the surgery, tied up thing probably because slide beside and become invalid, and the doctor often will drill holes in the main part bone, also simultaneously also drill holes in the corresponding position of bone fragment, cross the bone hole with the line and ligate, just so the effect is reliable. Because the bone tunnel is often not regular enough and the inner wall is rough, the thread is not easily threaded to the contralateral side. The current method is to make a thin metal tube into a semicircle, first pass it through the bone tunnel, and then pass the wire through the metal tube. There is a problem in that it is relatively easy to pass a hard thread, and it is difficult to pass a soft thread, which tends to extend the operation time.

The utility model discloses a chinese utility model patent that the grant bulletin number is CN204890143U discloses an orthopedic operation direction pincers, the utility model discloses an go up tong arm, lower tong arm have the guide way respectively at pincers body front end, and the guide way is crooked arc rectangular body, and the rear end of guide way is connected with the front end of last tong arm and lower tong arm, and the guide way has semicircular groove along the length direction of cell body, and semicircular groove's opening orientation is gone up the lower extreme direction of tong arm and lower tong arm, goes up tong arm and lower tong arm and folds the back, and two guide ways are relative, and steel wire or coping saw can pass in the guide way.

The device that above-mentioned patent provided can effectively simplify among the bone surgery long bone and cut bone, protect peripheral nerve, blood vessel and soft tissue when the operation is binded to the fracture piece, avoids causing unnecessary damage to peripheral tissue, shortens the operation time, reduces the possibility of postoperative complication, is fit for minimal access surgery and popularizes and applies in clinical treatment, but the device still exists not enoughly at the actual operation in-process: the device can only thread in the body in the operation, and the threading difficulty is increased by nonreactive factors such as bleeding in the operation and the like in the threading process; the device is feasible for threading steel wires and is difficult for threading.

An authorized announcement number is CN2836737, discloses a medical steel wire guider, and belongs to the technical field of medical appliances. The technical scheme of the utility model is that: the clamp handle is fixedly connected with the sleeve clamp mouth, the clamp handle is hinged with the clamp handle through a pin shaft, a steel wire outlet hole is formed in the sleeve clamp mouth, a steel wire inlet hole is formed in the sleeve clamp mouth, and two ends of the spring piece are respectively fixed on the clamp handle and the clamp handle.

The guider provided by the patent enables the steel wire to be easily wound, can effectively protect soft tissues, blood vessels and nerves around the fracture from being damaged, protects the blood circulation of bone fragments to the maximum extent and is beneficial to fracture healing; but in addition the device is relatively easy for hard threads to pass through and hard threads are difficult to pass through, often resulting in prolonged operation time.

In summary, the prior art has no reliable solution to the problem of how to quickly and effectively pass the cord through the bone canal, and thus the technical personnel in the field are always puzzled.
