Description

Steel wire cerclage wire passing device for diaphysis fracture

Technical Field

The utility model relates to a medical instrument, in particular to a wire cerclage wire passing device for diaphysis fracture.

Background

For the oblique or spiral fracture of long bone shaft, especially for the fracture around prosthesis, it is often necessary to perform fracture reduction first and then to perform the fixation by cerclage the fracture end with steel wire, and in order to further enhance the fixation effect, many cerclage procedures are usually required. In the operation, the operation visual field side of the backbone can be better exposed, but most areas of the backbone on the side opposite to the operation visual field are tightly attached to the autologous tissue, so that the front end of the steel wire is often shielded by the autologous tissue when the steel wire is looped through the backbone in the operation, the operation is very inconvenient, time is consumed, and soft tissue injury to a certain degree is also caused. Such problems are even more pronounced when multiple cerclage is performed.

In order to solve the problems, some auxiliary tools can help the steel wire cerclage diaphysis to a certain extent clinically, but the auxiliary tools have respective defects and still have great improvement space. A tool for assisting a steel wire to cerclage a backbone is a hook-shaped wire passing pipe with a hollow pipeline, and the operation method comprises the steps of firstly, bypassing the hook-shaped pipeline around the opposite side of the backbone, and then, penetrating a steel wire through an inner pipeline to achieve the purpose of surrounding the backbone; the disadvantages of this approach are: if the hook end is too long, the hook-shaped wire passing device is not beneficial to the hook-shaped wire passing device to bypass the backbone, and if the length of the hook end is insufficient, the tail end of the steel wire is still shielded by tissues and is difficult to find. In practical clinical application, the length of the hook end is generally greatly limited in order to enable the hook end to smoothly bypass the backbone, and the backbone is mostly deep, and the operable area is very narrow, so that the tail end of the steel wire is often difficult to find, and the operation is still very inconvenient.
