Description
Technical field
The present invention relates to a kind of operating theater instruments, particularly relate to a kind of Medical file.
Background technology
File is widely used in medical surgery operation, assist a physician to osseous tissue cut, the 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 fixedly connected with, 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 fixedly connected with.During dismounting, press the section that leans out of steady pin 4, its protuberance namely breaks away from fixed groove 21, therefore can with cutter hub 2 with body 1 is separated.
Above-mentioned Medical file, though really easy to use, 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, after Reusability, spring 3 were aging, cutter hub 2 was easily deviate from body 1, can therefore spin out operating time, and then affected the time of post-operative recovery seriously the time.
2, this structure is strict to the elastic force of spring, and elastic force is large, 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 to satisfy the be connected needs of body 1 with cutter hub 2, to require that body 1 is had larger thickness, thereby can impact in operation process, for doctor's sight line.
This shows, 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 affect the new Medical file of surgical field of view, one of real important subject that belongs to current this area.
Summary of the invention
The object of the invention is to, 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 affect surgical field of view, thereby more be suitable for practicality.
The object of the invention to solve the technical problems realizes by the following technical solutions.A kind of Medical file according to the present invention's proposition, 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 object of the invention to solve the technical problems 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.
The present invention compared with prior art has following obvious advantage and beneficial effect at least:
1, Medical file of the present invention, cutter hub with adopt body Tiebar structure to be connected, be connected firmly, reliably.
2, Medical file of the present invention, basically identical body thickness and cutter hub, in operation, can not affect doctor's the visual field, be convenient to observe, be fit to the small incision surgery needs, alleviate as much as possible patient's misery.
3, Medical file of the present invention lifts the crank depression bar and can take off cutter hub, and depressing the crank depression bar is the automatic locking cutter hub, changes convenient, fastly, reliable, and can effectively shorten operating time.
4, Medical file of the present invention 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, Medical file of the present invention, 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 affect surgical field of view.The present invention has above-mentioned plurality of advantages and practical value, it all has larger improvement in product structure and use, significant progress is arranged technically, and produced handy and practical effect, and more existing Medical file has outstanding effect, thereby more is suitable for practicality.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of description, and for above and other purpose of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and the cooperation accompanying drawing, be described in detail as follows.
Description of drawings
Fig. 1 is the structural representation of existing Medical file.
Fig. 2 is the structural representation of Medical file of the present invention.
