Description

Vaginal dilator

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a vaginal dilator.

Background

The vaginal dilator is a medical instrument commonly used in gynecological examination and diagnostic uterine curettage operation, and plays a role in enlarging the vaginal orifice so as to perform examination or operation in the vagina. Most of the vaginal speculum is duckbilled, and when the vaginal orifice is enlarged and then is inspected or operated, the vaginal speculum needs to be locked and fixed to prevent the vaginal speculum from being closed. However, most of the locking structures of the existing vaginal speculum are tooth-shaped clamping strip structures or spiral structures protruding outwards, and the protruding locking structures risk to stab patients in the actual use process.

Disclosure of Invention

The utility model aims to provide a vaginal dilator, the locking structure of which is hidden between an upper handle and a lower handle and does not protrude outwards, and the risk of stabbing a patient during use is avoided.

The technical aim of the utility model is realized by the following technical scheme:

the utility model provides a female expander, includes and is duckbilled expands the female expander and expands the female expander down, go up the female expander with down the female expander is kept away from the one end of its sharp of mouth and is articulated, go up the female expander and keep away from the one end of its sharp of mouth and be connected with the handle, down the female expander keep away from the one end of its sharp of mouth and be connected with down the handle, go up the female expander with when expanding the female expander to close down, go up the handle with there is the contained angle down between the handle, go up the female expander with go up the crossing department of handle and offered the observation opening, down the handle orientation go up handle one side be provided with many transversely setting and along the latch of its length direction equidistant distribution, the tooth tip of each latch all inclines upwards, go up the handle orientation down the lower part of handle one side is connected with the elastic connection strip, the free end of elastic connection strip be connected with the tooth form card strip of latch cooperation joint, the tip of tooth form card strip with the tooth tip opposite direction of latch.

Through adopting above-mentioned technical scheme, during the use, hand-held vaginal dilator is direct with just duckbill tip inserts patient's vagina, after inserting completely, grip handle and lower handle, make both be close to each other, drive and go up vaginal dilator and lower vaginal dilator and open, go up the handle and be close to in-process each other with lower handle, the elastic connection strip promotes tooth-shaped card strip upwards gradually with the latch joint of more top under the thrust effect, realize locking in optional position, when the inspection finishes needing to close vaginal dilator, only need with the finger stretch into upward promotion elastic connection strip between upper handle and the lower handle, make tooth-shaped card strip and latch joint not, alright operate upper handle and lower handle separately, make vaginal dilator closure, take out the completion inspection at last.

The utility model is further provided with: the middle part of lower handle orientation handle one side is inwards offered along its length direction and is provided with vertical bar groove, vertical bar inslot rotation is connected with the pivot, the lateral wall of pivot is connected with the push rod that sets up along its length direction, under the normality, the push rod income is in vertical bar inslot rotates the pivot, can make the push rod stretches out vertical bar groove will tooth form card strip release do not with the latch joint, the lower extreme of pivot downwardly extending the handle is connected with the knob down.

The utility model is further provided with: one end of the elastic connecting strip, which is far away from the toothed clamping strip, is connected with the lower part of the upper handle through an elastic strip, and the elastic strip is connected with the elastic connecting strip to form a V shape.

Compared with the prior art, the utility model has the following beneficial effects:

firstly, the vaginal dilator realizes locking at any position through the elastic connecting strip and the clamping teeth which are arranged between the upper handle and the lower handle, the locking structure does not protrude outwards, and the risk of stabbing a patient during use does not exist;

secondly, when the utility model needs to be closed, the toothed clamping strips can be prevented from being clamped with the clamping teeth only by rotating the knob, so that the locking can be easily released, and the vaginal dilator is closed.
