Description

Dual-purpose uterine cavity brush

Technical Field

The utility model relates to a sample collector, in particular to a dual-purpose uterine cavity brush.

Background

The original endometrium collector consists of a tube sleeve and a drawing rod, wherein the front end of the drawing rod is provided with a uterine cavity brush which can rotate in the uterine cavity to collect endometrium. However, the uterine cavity brush is unreasonable in structure, and in actual operation, the original endometrial collector cannot ensure the collection amount of a sample, so that clinical missed diagnosis is caused.

Disclosure of Invention

Aiming at the problems in the prior art, the utility model provides the dual-purpose portable endometrium collector which has reasonable structure and simple operation and can ensure the collection amount.

In order to achieve the above purpose, the present utility model provides the following solutions: a dual-purpose uterine cavity brush comprising: the utility model provides a compressible palace chamber brush, outer tube, push rod, there is a compressible palace chamber brush at the top of push rod, compressible palace chamber brush includes kicking block, bottom block to and a plurality of thin poles of fixed connection between kicking block and bottom block, be the lantern form after the compressible palace chamber brush stretches out the outer tube and open the structure, be equipped with a plurality of apertures on the top wall of outer tube, the afterbody of outer tube is equipped with the syringe connecting hole, and the length of outer tube is less than the push rod, and the push rod can freely pull in the outer tube to can take out the outer tube.

Further optimization of the above scheme: the syringe connecting hole at the tail of the outer sleeve is connected with the syringe after the push rod is pulled out, and negative pressure pumped by the syringe is applied to suck the tissue in the uterine cavity through a plurality of small holes on the top wall of the outer sleeve.

Further optimization of the above scheme: the thin rods of the compressible uterine cavity brush are provided with thin side wings, the compressible uterine cavity brush can freely rotate in the uterine cavity, and tissues in the uterine cavity are adhered through the side wings.

Further optimization of the above scheme: the outer sleeve is provided with scale marks.

Compared with the prior art, the utility model has the beneficial results that: according to the utility model, after the outer sleeve is in a compressed state and extends out of the outer sleeve, the compressible uterine cavity brush is in a lantern-shaped opening structure, and the original single-line uterine cavity brush is improved into a three-dimensional lantern-shaped opening structure, so that the contact area with endometrium is effectively increased, the collection amount of endometrium samples collected on the compressible uterine cavity brush after rotation is greatly ensured, and the phenomenon of clinical missed diagnosis is effectively avoided.

Detailed Description

In order to further understand the structural features of the present utility model, the present utility model will be further described with reference to the accompanying drawings.

As shown in fig. 1 and 2, a dual-purpose uterine cavity brush includes: the utility model provides a compressible palace chamber brush 23 is equipped with at the top of outer tube 2, push rod 1, the top of push rod 1 has a compressible palace chamber brush 23, compressible palace chamber brush 23 includes kicking block 25, bottom block 26 to and a plurality of thin poles 23 of fixed connection between kicking block 24 and bottom block 25, compressible palace chamber brush 23 stretches out and is the lantern form after the outer tube and opens the structure, is equipped with a plurality of apertures 22 on the top wall of outer tube 2, and the afterbody of outer tube 2 is equipped with syringe connecting hole 24, and the length of outer tube 2 is less than the length of push rod 1, and push rod 1 can freely pull in outer tube 2 to can take out outer tube 2.

The syringe connecting hole 24 at the tail of the outer sleeve 2 is connected with the syringe 3 after the push rod is pulled out, and the negative pressure pumped by the syringe 3 is applied to suck the tissue in the uterine cavity through a plurality of small holes on the top wall of the outer sleeve 2.

The thin rods 23 of the compressible uterine cavity brush 23 are provided with thin side wings 231, the compressible uterine cavity brush 23 can freely rotate in the uterine cavity, and tissues in the uterine cavity are adhered through the side wings 231.

The outer sleeve is provided with graduation marks 21.

With the adoption of the dual-purpose uterine cavity brush, firstly, the compressible uterine cavity brush 23 is inserted into the outer tube sleeve 2, then the top of the dual-purpose portable endometrium collector is inserted into the uterus, and the graduation marks 21 on the unexpected tube sleeve 2 are injected during insertion, so that the insertion is avoided, and the insertion is not performed at all. After the top is inserted, the compressible uterine brush 23 is pushed out of the sleeve, after the sleeve is pushed out, the side wings 231 on the compressible uterine brush 23 are opened, after the compressible uterine brush 23 is slightly rotated in the uterus, the whole push rod 1 is completely pulled out of the outer sleeve 2, then the injector 3 is connected to the injector connecting hole 24 at the tail part of the sleeve, the injector 3 is sucked, the residual tissue in the uterus is pumped into the outer sleeve 2 or the injector 3 through the plurality of small holes 22 on the pipe wall, and after the action is completed, the outer sleeve 2 is pulled out. Intra-uterine tissue is retrieved for medical analysis, both in the cuff and on the compressible brush 23. The aim of the utility model is achieved.

The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
