Description

Microscope supporting structure of expander

Technical Field

The invention relates to the technical field of medical instruments, in particular to a microscope supporting structure of a dilator.

Background

The vaginal dilator is a medical instrument for clinically diagnosing and screening gynecological diseases, and plays an important role in wedding examination, pregnancy examination and obstetrical examination.

The conventional vaginal dilator generally has an expansion structure and an image module for acquiring images, when the vaginal dilator is used, the dilator needs to be sent into the vagina, after the vagina is expanded to a certain space through the expansion structure, the images in the vagina are acquired through the image module, and then medical workers can judge the conditions of diseases according to the images. Because the position of the image module on the current vaginal dilator is mostly fixed, inconvenient regulation when using, and the function is single, can only shoot fixed region, therefore medical personnel use the dilator with the vagina expand back, still can send devices such as microscope, hysteroscope into the vagina when necessary to obtain more accurate image.

However, due to the instability of human hands, a device such as a microscope is likely to shake after being fed into the vagina, and when the dilator is used, a medical worker needs to expand the vagina with one hand and operate the microscope with the other hand, which is very inconvenient, and thus, a photographed image is easily blurred, and adverse effects are brought to diagnosis and treatment of diseases, and therefore, the structure of the existing dilator needs to be improved.

Disclosure of Invention

In view of the deficiencies of the prior art, the present invention provides a microscope support structure for a dilator.

The invention discloses a microscope supporting structure of a dilator, which comprises: a main body; the main body is provided with a supporting groove and a stop hole; a connecting seat; the connecting seat is inserted in the supporting groove and is provided with a pin hole; a sliding seat; the sliding seat is connected to the connecting seat in a sliding mode, a control hole is formed in the sliding seat, and a control inclined plane is arranged at the control hole; a supporting base; the supporting seat is arranged on the connecting seat, and an accommodating hole is formed in the supporting seat; a locking member; the locking piece penetrates through the pin hole, the control hole and the accommodating hole and corresponds to the stop hole; the locking piece is provided with a matching inclined surface, and the sliding seat slides on the connecting seat to enable the control inclined surface to be in contact with the matching inclined surface; a first elastic piece is arranged in the accommodating hole and connected between the locking piece and the supporting seat; and a second elastic piece is connected between the sliding seat and the connecting seat.

The beneficial effect of this application lies in:

the detachable connection of the microscope assembly on the main body is realized: in a free state, the second pin column of the locking piece is inserted into the stopping hole and is simultaneously under the pressure action of the first elastic piece, and at the moment, because the second pin column is blocked by the stopping hole, a user cannot pull out the connecting seat from the supporting groove of the supporting piece, so that the locking of the connecting seat and the main body is realized; when a user pushes the sliding seat, the control inclined surface can be in contact with the matching inclined surface and pushes the locking piece to move, so that the second pin column of the locking piece is separated from the locking hole, the first elastic piece is compressed to store elastic potential energy, and the locking hole does not block the second pin column at the moment, so that the user can pull the connecting seat to detach the connecting seat from the main body; therefore, the support assembly replaces the hand of a person to position the microscope assembly, the stability of the microscope assembly is improved, the operation of medical workers is more convenient, and the diagnosis and treatment efficiency of gynecological diseases is improved.
