Abstract

The utility model relates to an orthopaedic operative manipulation instrument. A simple steel wire fixation guiding device is formed by the sequential connection of three parts which are a holding handle, a connecting rod and a C-shaped guiding hook. The C-shaped guiding hook is a hollow pipeline, the connection part of the guiding hook and the conecting rod is provided with a steel wire inlet, the tip part outlet is a sharp inclined plane, and the bending wall of the C-shaped guiding hook, which is 4-6 mm far from the tip part outlet, is provided with a barb. The utility model has simple structure, is safe and convenient to use, is completely adhered to a bone surface when being used, causes the steel wire to be fixed in a winding way, can protect the integrity of soft tissues at the periphery of a periosteum and a fracture part, has light tissue damage, avoids damaging the tissues such as blood vessels, nerves, and the like, protects blood supply of the fracture part to the maximum, avoids the stress shielding caused by the fixation of a fracture part steel plate and an intramedullary nail, and is beneficial to fracture healing. Meanwhile, when the orthopaedic operative manipulation instrument is used for taking out the steel wire, the steel wire can be prevented from being fractured.

Description

Simple and easy fixation with steel wire guide

One, technical field:

This utility model relates to armarium, particularly the bone surgery operating apparatus.

Two, background technology:

Steel wire has superiority and the specificity of himself as a kind of material of fracture internal fixation, is difficult for being substituted by other fixtures, still has use value more widely in fracture internal fixation field.During traditional fracture fixation with steel wire, need fracture site is fully appeared, soft tissue such as periosteum is fully peeled off around far away, the nearly fracture end, needs fixed fractures with directly passing after the steel wire bending, or after utilizing mosquito forceps, right angle forceps with steel wire one end clamping, need passivity around the fractures surrounding tissue.In operation, the time invar silk come off, repeated multiple times can be successful.Complicated operation has prolonged operating time, increases the weight of, destroyed the fractures blood circulation, and the steel wire end easily stabs fractures peripheral vessels, nerve and soft tissue, influences union of fracture, increases operation risk and complication.Treat union of fracture, binding ring around steel wire chemical modification and steel wire take place in vivo ties up extremely flexural deformation in the process in operation, its linear intensity is subjected to than havoc, cause that the situation of steel wire fracture happens occasionally in extracting operation.

Three, summary of the invention:

The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of simple and easy fixation with steel wire guide is provided, and is simple in structure, safe in utilization, convenient, alleviates operation wound, multi-functional, practical.

The technical scheme that this utility model is adopted for achieving the above object is: simple and easy fixation with steel wire guide, it connects to form successively by controlling handle, connecting rod and C type guiding hook three parts, C type guiding hook is a hollow pipeline, guiding hook and connecting rod connecting portion have the steel wire inlet, the tip outlet is sharp property inclined-plane, and C type guiding hook has a barb apart from tip outlet 4-6mm inflection wall place.

Described C type guiding hook has barb apart from tip outlet 5mm inflection wall place.

This utility model is simple in structure; safe in utilization, convenient, can select suitable types according to the difference of fracture site; itself and surface of bone are adjacent to fully; steel wire around fixing, can be protected the complete of periosteum and fractures surrounding soft tissue, and disorganization is light; avoid tissues such as injured blood vessel and nerve; protected the blood supply of fractures to greatest extent, the stress shielding of having avoided fractures steel plate, intramedullary needle fixedly to cause simultaneously helps union of fracture.Application when it takes out steel wire simultaneously can effectively prevent effects such as steel wire fracture.Simultaneously C type guiding hook is apart from the barb at inlet 5mm inflection wall place, tip, and bifilar or steel wire strand safety, the method easily of providing be provided to need.Clinical Practice is used, and has operation safe, convenience, alleviates operation wound, is a kind of comparatively ideal fixation with steel wire operating theater instruments.This utility model mainly is adapted to the fracture fixation with steel wire and the taking-up of extremity tubular bone, particularly deep.According to the anatomical features of extremity tubular bone, can be divided into large, medium and small model.

Five, the specific embodiment:

Specify this utility model below in conjunction with accompanying drawing.

Simple and easy fixation with steel wire guide as shown in Figure 1, it is fixedly connected sequentially and forms by controlling handle 1, connecting rod 2 and C type guiding hook 3 three parts, C type guiding hook is hollow pipeline (as shown in Figure 3), C type guiding hook hollow pipe is that steel wire connects pipeline, guiding hook and connecting rod connecting portion have steel wire and entered the mouth for 4 (as shown in Figure 5), the tip outlet is the sharp property inclined-plane 5 shown in Fig. 2 and 4, and C type guiding hook has a barb 6 apart from tip outlet 5mm inflection wall place.

When fixedly steel wire uses, the operation range of exposure is little, and do not need around the cleavage fracture portion soft tissues such as periosteum, make distinctive sharp property inclined-plane, C type guiding hook tip, be close to annular surface of bone and walk around fractures, after steel wire very easily passed C type guiding hook, guide driven in the wrong direction shifts out, with the steel wire two ends tighten up gradually, ligation bone fixation folding part.

Use this guide can be after opening steel wire and twining ligation place, utilize the sharp property inclined-plane of C type guiding hook tip, comply with the circumferential direction of steel wire the backbone, with the two ends of steel wire by proximad far peeling off, steel wire is fully separated with the surface of bone of healing, reduce steel wire and surface of bone adhesion, prevent steel wire fracture in the taking-up process, can reduce the risk of tiny key refracture simultaneously.
