Steel wire pressurizing ligator

Abstract

The invention provides a steel wire pressurizing ligator which comprises a cuboid-shaped fixing body and a handle fixedly connected with the fixing body, two fixing hole channels used for allowing a steel wire to penetrate through and fixing the steel wire are symmetrically formed in the fixing body, threaded holes communicated to the fixing hole channels are symmetrically formed in the two sides of the fixing body, and fastening bolts are connected into the threaded holes in a threaded mode. The steel wire pressurization ligator is scientific and reasonable in structural design and convenient to manufacture, tension generated by the steel wire pressurization ligator is converted into pressure of a fracture broken end, effective pressurization of a steel wire in a tension band steel wire surgical operation can be achieved, bone healing is effectively promoted, steel wire ligation is simple and labor-saving, surgical steps are remarkably simplified, surgical time is shortened, and working efficiency is improved. And the device is good in use effect and can be popularized and used.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a wire pressure ligator. Background technique [0002] Tension band wire fixation is one of the classic internal fixation methods in trauma orthopedics. It is mainly used for open reduction and internal fixation of patella fractures, olecranon fractures, and anterior superior iliac spine avulsion fractures. The fixation of small bone fragments such as joint fractures can achieve compression between the fracture fragments and promote primary fracture healing. It is a classic internal fixation operation. The operation of tension band wire internal fixation mainly relies on the compression and ligation of the fracture fragments by tensioning the wire. However, in clinical applications, especially in the field of minimally invasive treatment of orthopedic surgery, there is no mature wire compression and ligation device. Traditional surgical methods often use a vise to tighte...

Problems solved by technology

However, in current clinical applications, especially in the field of minimally invasive orthopedic surgery, there is no mature wire pressurization and ligation device. Traditional surgical methods often use vise to tighten the wire, and then perform multiple rotations to ligate. The procedure is difficult, the soft tissue is severely traumatized, and there are problems such as insufficient pressure or wire breakage, which lead to operation failure.
