Hook threader

Abstract

The invention discloses a hook-shaped cable penetrating apparatus in the field of medical apparatus and instruments. The hook-shaped cable penetrating apparatus comprises a handle. A connecting straight rod is arranged on the handle, a bent head capable of being wound through a backbone is arranged at the front end of the connecting straight rod, a cable penetrating pore passage is arranged in the bent head and is perforated through two ends of the bent head to form two ports at the two ends of the bent head, the pore diameter of the cable penetrating pore passage is larger than the diameter of a cable and is smaller than the width of an obstruction head at the tail end of the cable, a notch which is perforated through the integral cable penetrating pore passage is arranged on the bent head, and the integral cable penetrating pore passage can be of an open structure with the notch on a side surface, so that the cable in the cable penetrating pore passage can be directly pulled out of the cable penetrating pore passage via the notch without being separated from the bent head; the notch is positioned on a concave surface of the inner side of the bent head. The hook-shaped cable penetrating apparatus has the advantages that users can conveniently take out the cable penetrating apparatus without cutting off the obstruction head after cable penetrating, secondary trauma on tissues around the backbone can be prevented, and the like.

Description

technical field [0001] The utility model relates to the field of medical equipment, in particular to a hook-shaped cable threader. Background technique [0002] In orthopedic surgery, when dealing with fractures and other situations, it is necessary to use cables to bind and fix the bones. Since there are soft tissues such as blood vessels, nerves, and muscles around the bones, when using cables to fix the bones, it is necessary to Try to avoid the damage caused by the cables binding these tissues, that is to say, the cables should be bundled as close to the bones as possible. However, since the doctor's field of vision and operating space are not very large during the operation, it is necessary to use a wearable The cable guide helps the doctor to carry out the operation of the cable. [0003] A cable threading device commonly used in the industry at present, its structure includes: a handle, a connecting straight rod is arranged on the handle, and an elbow that can bypass...

AI Technical Summary

Problems solved by technology

[0005] The cable threader with the above structure has the following disadvantages: 1. If the head end of the cable without the blocking head is selected to be inserted from the near port during use, the cable cannot be taken out and passed through without cutting off the blocking head at the end of the cable. After cutting off the blocking head, you can only use a double-headed cable tightening gun to tighten the cable in the next cable tightening process, which not only increases the difficulty of operation, but also has poor cable tightening effect, and it is easy to The cable is loose; 2. If the first end of the cable without the blocking head is reversely threaded from the far port, then when the cable threader is taken out, the elbow must be moved along the cable bit by bit. Back out, so that the elbow will cause secondary trauma to the tissues around the backbone, which will aggravate the soft tissue damage
