Vaginal dilator for gynecology department

Abstract

The invention relates to the field of medical instruments, and particularly discloses a vaginal dilator for the gynecology department. The vaginal dilator comprises two handles, wherein hinge parts are arranged at the upper ends and the lower ends of the handles; the upper ends of the two handles are each connected to a placement cylinder rotationally, and the lower ends of the two handles are each connected to another placement cylinder rotationally; a core rod and a pushing jacking spring are limited in each of the two placement cylinders; the opposite end parts of two core rods are each connected to a combined seat, and two combined seats are each combined with an expansion sheet; and a non-return mechanism and a station groove are arranged in each placement cylinder, and two limiting blocks are fixed on each handle. When the handles are rotated to the position right behind the two placement cylinder, the two limiting blocks exactly enter two station grooves correspondingly, non-return mechanisms allow the two core rods to get close to the middle, and the two core rods can be prevented from getting away from each other. The vaginal dilator for the gynecology department is basedon ingenious structural design, convenient and fast to use, balanced in dilation force, sufficient in dilation space, capable of being suitable for different patients with large individual differences, and capable of being adjusted to the optimal dilation state according to the clinical actual situation.

Description

technical field [0001] The invention relates to a medical device, in particular to a vaginal dilator used in gynecological clinical examination and treatment. Background technique [0002] Vaginal dilator, also known as vaginal dilator, is often used to dilate the vagina in the routine examination and surgical treatment of gynecological diseases to obtain a better inspection field of view or surgical field. It is a commonly used medical device in gynecology. It usually consists of a Composed of expansion wings and handles, the two expansion wings are duckbill-shaped and the rear ends are hinged, and the handle is set at the tail end of the two expansion wings. The opening angle of the two expansion wings can be adjusted and the position of the two expansion wings can be locked by using the handle. In this way, the expected expansion purpose is achieved. Since most of the existing vaginal dilators adjust the degree of expansion by adjusting the opening angle, in the course o...

AI Technical Summary

Problems solved by technology

Since most of the existing vaginal dilators adjust the degree of expansion by adjusting the opening angle, in the course of clinical use, the expansion degree applied by the expansion wings to the vagina from the inside to the outside is often inconsistent and unbalanced, which is easy to cause The patient suffers severe pain or even contusion due to excessive local force; especially when the two expansion wings open at a large angle, although the inside of the vagina will be fully expanded, the part close to the vaginal opening is difficult to be fully expanded, and the vaginal dilator The rear port of the expansion wing is usually closed-loop, which often forms a "bottleneck" that hinders operations such as inspection and surgery; in addition, because the tail ends of the two expansion wings are connected by hinges, the hinges will block the doctor's line of sight to a certain extent

In summary, the structure design of the existing vaginal dilators is not reasonable enough. During use, it is difficult to adjust to the best dilation state according to the actual clinical conditions such as individual differences in patients and the purpose of dilation.
