Description

Repositor for adherent fracture with tendon

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a restorer of taking tendon to adhere to fracture.

Background

Fracture reduction is an important link in orthopedic surgery, small fracture blocks attached to tendons are difficult to reduce in the operation due to tendon traction, or are difficult to temporarily fix after reduction, and the small fracture blocks are generally fixed by forceps clamps and difficult to fix, and even can be completely free or fractured.

In addition, most fracture reductors commonly used at present are used for bone fracture of the backbone and reset by clamping bone blocks, and when the bone fracture reductors are implanted into internal fixation objects, the visual field effect is poor due to the blockage of the reductors. While loss of reset occurs while the reset is released. After the clamping is reset, the electric drill is used for penetrating a needle to be temporarily fixed, and then the fixed object is replaced, so that damage and aggravation can be caused. When a small bone fracture block, especially a small bone fracture block attached to a tendon is reduced by using a clamp or is directly fixed by suturing with a thick thread, the fracture block may be dissociated or broken when the tendon has a large tension, and the operation quality is seriously affected. Therefore, the existing fracture repositor cannot be used for the adhesion condition of the tendon of the tiny fracture belt.

In addition, the fracture block is fixed by means of stitching and reduction after being drilled, the steel wire needs to be taken out after secondary operation, and the fracture block is fixed through silk threads. At present, no smooth resetting instrument exists.
