Description

Medical file

Technical field

This utility model relates to a kind of operating theater instruments, particularly relates to a kind of medical file.

Background technology

File is widely used in medical surgery operation, assist a physician to osseous tissue cut, operations such as engraving, grinding, osteotomy.See also shown in Figure 1ly, existing medical file is by body 1, cutter hub 2, spring 3 and steady pin 4 are formed.Wherein, the connection handle of cutter hub 2 is provided with fixed groove 21.Spring 3 be positioned at body 1, one end with body 1 is fixedlyed connected, the other end is connected with steady pin 4.Steady pin 4 leans out a body 1, and is provided with the protuberance that mates with groove 21.During use, the protuberance of steady pin 4 snaps in the fixed groove 21 of cutter hub connection handle, cutter hub 2 with body 1 is fixedlyed connected.During dismounting, push the portion that leans out of steady pin 4, its protuberance promptly breaks away from fixed groove 21, therefore can with cutter hub 2 with body 1 is separated.

Above-mentioned medical file, though easy to use really, have progressive, but when reality is used, find also to have some shortcomings in its structure, cause this medical file in practical application, fail to reach best result of use, and its shortcoming can be summarized as follows:

1, use repeatedly, spring 3 aging after, cutter hub 2 is deviate from easily body 1, can therefore spin out operating time, and then influences the time of post-operative recovery seriously the time.

2, this structure is strict to the elastic force of spring, and elastic force is big, and effort is excessive when then changing cutter hub, and elastic force is little, then cutter hub with become flexible and be connected insecure body is easy.

3, in order satisfying, to require that body 1 is had bigger thickness, thereby can to impact in operation process, for doctor's sight line the needs that are connected of body 1 with cutter hub 2.

This shows that above-mentioned existing medical file obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.How to found a kind ofly make cutter hub and body be connected firmly, easy to loading and unloading, quick, is beneficial to and improves operation efficient, and overall structure is simple, thinner thickness does not influence the new medical file of surgical field of view, one of real important subject that belongs to current this area.

The utility model content

The purpose of this utility model is, overcome the defective that existing medical file exists, and provide a kind of medical file of new structure, technical problem to be solved be make its cutter hub with body be connected firmly, easy to loading and unloading, quick, be beneficial to and improve operation efficient, and overall structure is simple, thinner thickness, do not influence surgical field of view, thereby be suitable for practicality more.

The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to a kind of medical file that the utility model proposes, comprise body, cutter hub and spring, the connection handle of cutter hub is provided with fixed groove, also comprise: tapered end, connecting rod and crank depression bar, wherein tapered end one end is provided with the pothook that mates with fixed groove, the other end with body is rotatably connected, the connecting rod front end is rotationally connected with tapered end near other end place; The front end of the rear end of connecting rod and crank depression bar is rotatably connected; The crank depression bar near the front end place with body is rotatably connected; Spring one end is connected in a body, and the other end is connected in the connecting rod rear portion.

The purpose of this utility model and solve its technical problem and also can be applied to the following technical measures to achieve further.

Aforesaid medical file, described tapered end, crank depression bar respectively by fixed axis with body is rotatably connected.

Aforesaid medical file, described connecting rod is rotatably connected with tapered end and crank depression bar respectively by movable rotating shaft.

Aforesaid medical file describedly is provided with groove to body, and tapered end, connecting rod, crank depression bar and spring all are positioned at this groove.

This utility model compared with prior art has following tangible advantage and beneficial effect at least:

1, the medical file of this utility model, cutter hub with adopt body Tiebar structure to be connected, be connected firmly, reliably.

2, the medical file of this utility model body thickness and cutter hub basically identical, can not influence doctor's the visual field in operation, be convenient to observe, and is fit to the small incision surgery needs, alleviates patient's misery as much as possible.

3, the medical file of this utility model lifts the crank depression bar and can take off cutter hub, depresses the crank depression bar and promptly automatically pins cutter hub, changes convenient, fastly, reliable, and can effectively shorten operating time.

4, the medical file of this utility model can be connected body with the cutter hub of various model specifications and to be used in combination, and is beneficial to the saving cost.

In sum, the medical file of this utility model, cutter hub with body is connected firmly, easy to loading and unloading, quick, is beneficial to and improves operation efficient, and overall structure is simple, thinner thickness does not influence surgical field of view.The utlity model has above-mentioned plurality of advantages and practical value, it all has bigger improvement in product structure and use, obvious improvement is arranged technically, and produced handy and practical effect, and more existing medical file has outstanding effect, thereby is suitable for practicality more.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of description, and for above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, below especially exemplified by preferred embodiment, and conjunction with figs., be described in detail as follows.
