Abstract

The utility model discloses a medical super stable micro thorax opener. The medical micro thorax opener consists of two supporting arms and a hinge, wherein one ends of the two supporting arms are movably connected and are opened outwards by an elastic steel wire and the other ends of the two supporting arms are provided with corners; the hinge is connected with the two supporting arms; one end of the hinge is fixed on one supporting arm and the other end of the hinge is screwed on the other supporting arm by a bolt; and the hinge is regulated by the tightness degree of the bolt. When in use, the medical micro thorax opener is simple to use, is stable in openness, has a wide view field, never generates rib fracture of an animal, meanwhile, is low in cost, is simple to maintain and has a good opening effect.

Description

A kind of medical overstable miniature thorax dilator

Technical field

This utility model relates to a kind of medical surgical instrument field, relates in particular to medical miniature thorax dilator.

Background technology

In recent years, along with the development of China's medical science and medical research often needs, various laboratory animals are carried out thoracic operation and then carried out medical research; Because needs expose surgical field of view, often need thorax dilator; Laboratory animal is because its health is less, and animal rib is very thin easily broken, and adjacent rib gap is narrower, lacks corresponding thorax dilator, usually because surgical field of view is unclear, finally causes operative failure, affects research effect.Utility model small volume, the thorax dilator that applicable toy is used has great significance.

The thorax dilator that toy is used both at home and abroad is at present less, mostly is suture and substitutes.For this reason, it is low that we just determine to design a kind of cost, safeguards simply, struts effective toy thorax dilator.

Utility model content

The purpose of this utility model is to provide a kind of cost low, safeguards simply, struts effective toy thorax dilator.

For reaching this object, this utility model by the following technical solutions:

This medical miniature thorax dilator is comprised of two support arms and a hinge, wherein two support arm one end are flexibly connected, and outwards strut with elastic wire, the other end is with corner, two support arms of described chain connection, hinge one end is fixed on support arm, and the other end is screwed on another support arm by bolt, and the degree of tightness by bolt regulates hinge.Because the medical dilator using has one jiao to be hinged, make us in use only need fixedly opposite side, only need fix a bolt, very easy to use; Because medical dilator has corner, thorax is strutted to area large, broad view.

Preferably, described two support arms become a triangle with a hinge design.Owing to adopting triangular design, utilize two temples of triangle to open rib, expose surgical field of view, another limit can also be fixed strutting simultaneously, forms stable triangle.

Preferably, described two support arms have certain radian simultaneously, owing to being radian design, more fit with health.

The beneficial effects of the utility model are: this thorax dilator in use, is used simply, struts stablely, and animal fracture of rib, never appears in broad view, and cost is low simultaneously, safeguard simply, strut effective.

Accompanying drawing explanation

Fig. 1 is the front view structure chart of this utility model embodiment;

Fig. 2 is the side view structure chart of this utility model embodiment.

The specific embodiment

Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.

As Fig. 1 and Fig. 2, this medical miniature thorax dilator is comprised of two support arms 1 and a hinge 2, wherein two support arm 1 one end are flexibly connected, and outwards strut with elastic wire 3, the other end is with corner 4, and described hinge 2 connects two support arms 1, and hinge 2 one end are fixed on support arm 1, the other end is screwed on another support arm 1 by bolt 5, by the degree of tightness of bolt 5, controls hinge 2.During use, the chest of doing the toy of testing is cut, this this kind of medical miniature thorax dilator drawn in, bolt on hinge 25 is unscrewed, put into the otch of thorax, now the link due to support arm 1 has outside elastic wire 3, two support arms 1 outwards open, when opening up into suitable degree, tight a bolt 5, bolt 5 is fixing in place by hinge 2.Meanwhile, owing to there being corner 4 on support arm 1, thorax can be strutted to area large, broad view, is conducive to operation and experiment.

As a kind of improvement, two support arms 1 and a hinge 2 are designed to a triangle, owing to adopting triangular design, utilize two temples of triangle to open rib, expose surgical field of view, another limit can also be fixed strutting simultaneously, forms stable triangle, and this triangle can regulate, distraction angle becomes distraction angle wedgewise, along rib angle, the fracture of rib that can not occur together while making rib interval support Datong District, brings huge help to the animalcule thoracic operation of this experiment.

As another kind, improve, two support arms 1 are carried out to bending, make it there is certain radian simultaneously, can more fit with the animal bodies of this experiment like this.

The above; it is only the preferably specific embodiment of this utility model; but protection domain of the present utility model is not limited to this; any people who is familiar with this technology is in the disclosed technical scope of this utility model; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.

Claims
