Abstract

The utility model relates to a sternum fixing clip, which is characterized in that the sternum fixing clip is composed of a monomer beam (1) and a U-shaped hump hook (2) which is connected with the two ends of the beam (1). The utility model is used to fix the inner part of the sternum after the sternum is longitudinally opened or is used to reset the fractured sternum. With reasonable structure and reliable fixing, the utility model is favorable for the blood supply of skeleton of sternum to reconstruct and for the skeleton to grow and recover.

Description

The fixing card of breastbone

Technical field

This utility model relates to a kind of implantable medical utensil, is specifically related to a kind of fixing card of breastbone that breastbone vertically cuts back or the internal fixation that fracture of the sternum resets that is used for.

Background technology

At present, it is cardiothoracic surgery operative approach commonly used that breastbone vertically cuts, and the traditional method of the internal fixation that resets of operation closed breastbone in back and fracture of the sternum has: steel wire is worn in method 1, breastbone punching in advance; Method 2, sewing needle threading steel silk; Method 3, can absorb breastbone nail.Wherein, method 1 and method 2 all adopt wire binding, and punching or pass breastbone with sewing needle on breastbone all might cause damage to internal organs when wearing steel wire and wearing sewing needle, suprasternal punching or sew up pinprick and may cause hemorrhage; If tie wire is pine, fixing not firm to breastbone, do not have firm effect, if the tie wire tension may cause steel wire tension to cross major rupture, do not have fixation, also might cause damage to infrasternal internal organs, cause the generation of malpractice; And the postoperative steel wire takes out difficulty.Method 3 also needs breastbone punching and wire binding when using the breastbone nail, its weak point and method 1, method 2 are equal to substantially.

Summary of the invention

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, fixing reliable, and what help that breastbone skeleton myocardial revascularization and bone growth recover is used for the fixing card of breastbone that breastbone vertically cuts the internal fixation that back or fracture of the sternum reset.

The purpose of this utility model is achieved in that the fixing card of a kind of breastbone, it is characterized in that: the fixing card of this breastbone is made up of monomeric crossbeam and the U-shaped crotch that is connected as a single entity with described crossbeam two ends respectively.

Above-mentioned crossbeam can be flat, or arc shape, or its middle part is that flat, two ends arc-shaped transition are connected with described U-shaped crotch.

The cross section of above-mentioned crossbeam and described U-shaped crotch can be rectangle, or is oval or for circular, the end of the gib head of described U-shaped crotch is a pointed shape.

The cross section of above-mentioned U-shaped crotch is oval or for circular, the end of the gib head of its U-shaped crotch also can be taper.

Any surface finish of above-mentioned crossbeam and described U-shaped crotch, its planar crossing rib and sharp corner rounding.

Can adopt above-mentioned crossbeam and described U-shaped crotch cross section for oval, described crossbeam is an arc shape, the end of described gib head is the fixing card of the breastbone of taper.

The cross section that also can adopt above-mentioned crossbeam and described U-shaped crotch is for circular, and described crossbeam is a bending, and the plane at this plane, bending segment place and two described U-shaped crotch end face places is perpendicular, and the end of described gib head is the fixing card of the breastbone of taper.

Breastbone of the present utility model fixedly card can use various types of built-in alloy materials with shape memory function of human body that are applicable to make.

Cross section is that the volume that takes up room of the fixing card of the breastbone of rectangular configuration is less, the intensity height, and circular, that ellipsoidal structure takies the periosteum surface area is less; The fixing card of breastbone of the beam structure of the shape that should adapt according to the outer surface form selection of human body breastbone connecting portion in addition.

Breastbone of the present utility model fixedly is stuck in when using, when operation technique in the thoracic cavity is finished or after fracture of the sternum resets, breast device or patella reduction forceps are accurately temporary fixed with breastbone para-position place with closing, get the breastbone width between measuring device measurement left-right symmetric two rib intervals, selection is slightly less than the fixing card of breastbone of the present utility model than breastbone width data and installs, can select the fixing card of breastbone of different structure at different fixed positions, required fixed position is measured one by one install and fix after, unload ShiShimonoseki breast device or patella reduction forceps, check, clean, skin suture, operation is finished.

The utility model has the advantages that: 1, adopted the alloy material with shape memory function, operation technique is very easy when making cardiothoracic operation closure breastbone.2, improve the safety coefficient of operation technique, reduced the risk of malpractice.3, effectively shorten operating time, reduced patient's misery.4, simplicity of design, rational in infrastructure, meet the architectural feature of skeleton, to breastbone play safety, effectively, fixation reliably.5, the single-beam of middle beam design, the blood fortune that effectively reduces the breastbone surface is blocked, and helps the growth of the myocardial revascularization and the periosteum soft tissue of breastbone.6, the healing postoperative takes out safety, easy.Volume is little, and it is not obvious that foreign body is felt, even does not need to take out after the patient who the has healing.

In sum, of the present utility modelly be used for breastbone vertically to cut the breastbone fixing structure of back or the internal fixation that resets of fracture of the sternum reasonable, fixing reliable, help breastbone skeleton myocardial revascularization and bone growth and recover.
