AI Technical Summary
The existing obstetrics and gynecology vaginal expanders require a doctor to press the handle all the time after the vagina is opened to prevent it from being closed on its own, which leads to inconvenient operation and affects the efficiency of the examination.
A vaginal expander including the first clamping arm and the second clamping arm is designed, and the automatic limit is achieved through the structure of the sliding sleeve, the pin, the spring and the connecting rod. Combined with a semi-elliptical expansion head made of rubber material, the clamping arm is allowed. After rotation, it is fixed by itself, freeing the user's hands.
It realizes that there is no need to continuously grasp the handle after vaginal expansion, which facilitates the doctor to perform examination operations and improves the convenience and comfort of examination.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a vaginal dilator for obstetrics and gynecology. Background Art
[0002] Gynecologists often need to use a vaginal dilator when examining female patients' vaginas. The currently used vaginal dilators require doctors to keep pressing the handle after stretching the vagina to prevent the dilator from closing on its own. Since the doctor needs to keep pressing the handle of the dilator, it will cause inconvenience to the doctor and affect his examination operation. Utility Model Content
[0003] 1. Technical issues to be resolved
[0004] In order to overcome the shortcomings of the prior art, a gynecological vaginal dilator is proposed to solve the problems raised in the above background technology.
[0005] (II) Technical solution
[0006] The utility model is implemented through the following technical scheme: the utility model proposes a vaginal dilator for obstetrics and gynecology, including a first clamp arm and a second clamp arm, the first clamp arm and the second clamp arm are connected by a middle rotating shaft, a sliding sleeve is arranged at the tail of the first clamp arm, and the sliding sleeve and the first clamp arm can be fixed by a pin, the pin is connected to the sliding sleeve by a spring, a connecting rod is hinged on the sliding sleeve, and the other end of the connecting rod is hinged on the second clamp arm, expansion heads are arranged at the front end of the first clamp arm and the second clamp arm, and after the first clamp arm and the second clamp arm are rotated, the expansion heads thereon can be connected correspondingly.
[0007] Furthermore, finger rings are disposed at the tails of the first clamp arm and the second clamp arm.
[0008] Furthermore, the expansion head is made of rubber.
[0009] Furthermore, the expansion head is semi-ellipsoidal.
[0010] (III) Beneficial effects
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The utility model discloses a vaginal dilator for obstetrics and gynecology, which can free the hands of the user after the dilating head supports the opened vagina of the patient, so as to facilitate the user to perform inspection operations. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a schematic diagram of the structure of the utility model.
[0014] 1-first clamping arm; 11-sliding sleeve; 12-latch pin; 13-spring; 14-connecting rod; 2-second clamping arm; 3-expansion head; 4-finger ring. DETAILED DESCRIPTION
[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0016] like Figure 1 The gynecological vaginal dilator shown in the figure includes a first clamp arm 1 and a second clamp arm 2, the first clamp arm 1 is connected to the middle rotating shaft of the second clamp arm 2, a sliding sleeve 11 is set at the tail of the first clamp arm 1, and the sliding sleeve 11 and the first clamp arm 1 can be fixed by a pin 12, and the pin 12 is connected to the sliding sleeve 11 through a spring 13, a connecting rod 14 is hinged on the sliding sleeve 11, and the other end of the connecting rod 14 is hinged on the second clamp arm 2, an expansion head 3 is set at the front end of the first clamp arm 1 and the second clamp arm 2, and after the first clamp arm 1 and the second clamp arm 2 are rotated, the expansion heads 3 thereon can be connected correspondingly.
[0017] As a preferred embodiment, finger rings 4 are provided at the tails of the first clamp arm 1 and the second clamp arm 2, and the finger rings 4 can facilitate the user to turn the corresponding clamp arm to control the opening and contraction of the expansion head 3 at the front end of the clamp arm.
[0018] As a preferred embodiment, the expansion head 3 is made of rubber material to improve its comfort when in contact with the patient's vagina.
[0019] As a preferred embodiment, the expansion head 3 is semi-ellipsoidal in shape, which facilitates its insertion into the patient's vagina and provides comfort when it contacts the inner wall of the patient's vagina while supporting and opening the patient's vagina.
[0020] The utility model provides a vaginal dilator for obstetrics and gynecology. When in use, after supporting the opened vagina of the patient, the user does not need to continuously grasp the opened clamp arms, thereby freeing the user's hands and facilitating the inspection operation.
[0021] Specifically, after the expansion head 3 is inserted into the patient's vagina, the first clamp arm 1 and the second clamp arm 2 rotate relative to each other, so that after the expansion head 3 opens the patient's vagina, the first clamp arm 1 and the second clamp arm 2 can be supported and limited by the insertion and fixation of the sliding sleeve 11 and the first clamp arm 1 by the pin 12, thereby freeing the user's hands and facilitating the inspection operation.
[0022] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
