Multi-wing vaginal speculum

Abstract

The invention relates to a multi-wing vaginal speculum, which is characterized in that a tube body adopts a hollow rectangular prism structure, four edges of a port on one side of the tube body are connected with at least four wings, the wings can move up and down along folding slots and can be folded towards the tube body, an expansion device is arranged in the cavity of the tube body and adoptsa hollow rectangular prism structure with the same shape as the tube body after the same proportional contraction and expansion, the outer edge of the expansion device is matched with the inner edge of the tube body, the expansion device is also provided with a positioning pull rod, and the positioning pull rod can be moved for flexing of the expansion device in the tube body. When the expansion device is moved towards the wings until the port of the expansion device is contacted with the inner surfaces of roots at connection parts of the wings and the folding slots, the wings are expanded outwards in the folding slots. When the expansion device is moved in a direction opposite to the wings, the wings can be folded inwards in the folding slots. When the multi-wing vaginal speculum is used, the skin of a human body cannot be damaged, pains of patients can be reduced, the use is more humane, the cervix can be exposed fully, the operation of doctors can be facilitated, the operational time can be shortened, difficulties in operations and risks of operations can be reduced, and the effects of operations can be improved.

Description

technical field [0001] The invention relates to a multi-wing vaginal dilator, which belongs to the field of medical instruments and is used for stretching the vagina during operations such as gynecological examination or vaginal operation to fully expose the cervix for easy operation. Background technique [0002] At present, the structure of the vaginal dilator in the prior art is simple, and has the following disadvantages: one is that the existing vaginal dilator only separates the two parts up and down to stretch the vagina, and there are vaginal tissues on both sides of the opened vaginal dilator, so that the cervix can be enlarged. Less than full exposure is not conducive to observation and operation; second, the existing vaginal dilator is opened and closed through the shaft, and the fur and vaginal tissue are easily pinched during use; third, the existing vaginal dilator is easy to be squeezed out vaginal.
