Description

Transversely-expandable vagina retractor

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a vaginal retractor capable of being transversely expanded.

Background

The gynecological examination mainly comprises a general examination, an abdominal examination and a pelvic examination. Examination of vulva, vagina, cervix and uterus, fallopian tube, ovary and parauterine tissue and pelvic cavity wall. The main function is to make early diagnosis, prevention and early treatment for some gynecological diseases; in the gynecological examination process, the vaginal draw hook is one of the most common gynecological instruments, and brings great convenience to the examination work of medical personnel. However, the existing vaginal retractor has poor use effect and limited enlarged opening, thereby reducing the operation visual field and being inconvenient for the operation of doctors.

SUMMERY OF THE UTILITY MODEL

The utility model provides a vagina drag hook capable of being transversely expanded, which solves the problem of poor using effect in the background technology.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a but lateral expansion type vagina drag hook, includes the main blade, main blade one end fixedly connected with draw hook rod, one side of main blade is provided with the vice blade of second and first pair blade respectively, one side fixedly connected with guide rail of draw hook rod, the one end of the vice blade of first pair blade and second all is connected with the slider, two the slider all with guide rail sliding connection, the inside of slider is provided with stop gear.

Preferably, the limiting mechanism comprises a screw, and the screw is in threaded connection with the sliding block.

Preferably, one end of the draw hook rod is fixedly connected with a handle.

Preferably, a right angle is formed between the main blade and the draw hook rod, the top end of the main blade is a curved surface, and the main blade is narrow in front and wide in back.

The utility model provides a can transversely expand type vagina drag hook possesses following beneficial effect:

this but lateral expansion type vagina drag hook, slide in the guide rail outside through controlling two sliders, make first pair blade and the vice blade of second be the state of external rotation, then the screw is twisted to the accessible, make the slider fixed to the guide rail on, thereby fix first pair blade and the vice blade of second, can adjust the expansion width of first pair blade and the vice blade of second according to the size demand of operation doctor to the operation region in a flexible way, two vice blades of expansion are the arc and more laminate with the vagina, it is more clear to make the operation field of vision expose, can also avoid exposing the area because of the drag hook inadequately, the pain or uncomfortable sense that the main leaf brought for the operation person are rotated in a round trip, the result of use of device is improved.

Drawings

Fig. 1 is a schematic structural view of the present invention.

In the figure: 1. a main blade; 2. a first secondary blade; 3. a second set of blades; 4. a guide rail; 5. a slider; 6. a drawbar; 7. a screw; 8. and (4) carrying out handle.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The first embodiment is as follows:

referring to fig. 1, a transversely expandable vaginal retractor comprises a main blade 1, a retractor rod 6 is fixedly connected to one end of the main blade 1, a second auxiliary blade 3 and a first auxiliary blade 2 are respectively arranged on one side of the main blade 1, a guide rail 4 is fixedly connected to one side of the retractor rod 6, sliders 5 are respectively connected to one ends of the first auxiliary blade 2 and the second auxiliary blade 3, the two sliders 5 are respectively in sliding connection with the guide rail 4, a limiting mechanism is arranged inside the slider 5 and comprises a screw 7, the screw 7 is in threaded connection with the slider 5, the first auxiliary blade 2 and the second auxiliary blade 3 are in an outward rotating state by controlling the two sliders 5 to slide outside the guide rail 4, and then the screw 7 can be screwed to fix the slider 5 to the guide rail 4, thereby fix first auxiliary blade 2 and the auxiliary blade 3 of second, can come nimble expansion width of adjusting first auxiliary blade 2 and the auxiliary blade 3 of second according to the size demand of operation doctor to the operation region, two vice leaves of expansion are the arc and more laminate with the vagina, it is more clear to make the operation field of vision expose, can also avoid exposing the area because of the drag hook inadequately, the pain or the uncomfortable sense that main blade 1 brought for the art person of the back and forth rotation, the result of use of device has been improved, and when the operation begins to put into and the operation finishes withdrawing from, the auxiliary blade 2 of first auxiliary blade and the auxiliary blade 3 of second are adduction state, it is more light in the operation when putting into like this and taking out, the experience sense of bringing the art person is also more slight.

Example two:

one end fixedly connected with hand (hold) 8 of drag hook pole 6, form the right angle between main blade 1 and the drag hook pole 6, the top of main blade 1 is the curved surface, and the shape of main blade 1 is narrow back width, because first vice blade 2 and the second vice blade 3 can abduct when the operation, exposes wide enough operation field, so on the basis of alleviateing that the operation person puts into uncomfortable, still enlarged operation field.

In conclusion, when the transversely-expandable vaginal retractor is used, the first auxiliary blade 2 and the second auxiliary blade 3 are placed into a human body in an adduction state, then the two sliders 5 are controlled to slide outside the guide rail 4, so that the first auxiliary blade 2 and the second auxiliary blade 3 are in an outward rotation state, then the screws 7 can be screwed, so that the sliders 5 are fixed on the guide rail 4, the first auxiliary blade 2 and the second auxiliary blade 3 are fixed, the operation visual field is exposed clearly, and after the operation is completed, the first auxiliary blade 2 and the second auxiliary blade 3 can be withdrawn in the adduction state.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
