Abstract

The utility model relates to a collector for endometrium cell, which is composed of a core bar, two doctor blades and a casing tube. The doctor blades are connected at the front end of the core bar, both extend the casing tube and form an included angle, the external side of two doctor blades are provided with pellets, the diameters of the pellets are greater than the diameter of the casing tube, the tail end of the core bar has a handle, a pair of positioning forks are arranged in front of the handle, the distance between the forks and the front end of the core bar is the same as the length of the casing tube, and the diameter of the casing tube is corresponding to cervical canals. The utility model, a disposable medical appliance, has the advantages of simple structure, convenient operation, favorable effect, no pollution of sample, analgesia, and low cost.

Description

Collector for endometrium cell

This utility model relates to a kind of gynecological medical apparatus and instruments, particularly a kind of endometrial cell catcher.

The endometrium sampling is undertaken by diagnostic branch erasion usually in the hospital, needs the cervix dilating pipe, and except that patient's misery, the sampling thing is easily contaminated by cervical canal and vagina the time, makes result of laboratory test wrong.

China's utility model communique discloses a kind of uterine cavity sampler (CN2099551U), and by inner sleeve, trocar sheath, probe tube and holder are formed, the probe tube softness, and the band hairbrush, holder is positioned at the sampler front portion, and this sampler is for being repeatedly used apparatus.

The purpose of this utility model is that design is a kind of simple to operate, and it is effective to take a sample, and it is pollution-free to take a sample, the disposable gynecological medical apparatus and instruments that cost is low.

This utility model has been realized above-mentioned purpose with its simple structure, it is made of core bar, two scraping blades and thin sleeve pipe, two scraping blades are connected the core bar front end, one angle is arranged between the scraping blade, wherein a bead is arranged at a scraping blade top, sphere diameter is greater than thin casing inner diameter, thin cover external diameter of pipe equals 3mm, and it is handle that there are sword, core bar afterbody in two scraping blade outsides, there is a pair of location fork in handle the place ahead, the length of pitching the core bar front end is identical with thin casing length, and casing pipe sleeve has the metric system scale in the core bar outside on it, when not using, two scraping blades stretch out outside thin sleeve pipe.

Its operation principle is: before the sampling, earlier two scraping blades are shunk in thin sleeve pipe, by little spherical cap at thin sleeve pipe top; scraping blade is not contaminated, during use, earlier catcher is sent into uterine cavity (because of bead and sleeve pipe all very thin; and the about 3mm of cervical canal diameter; therefore, stretch into uterine cavity and do not need the cervix dilating pipe, can not cause suffering); then thin sleeve pipe is retreated; core bar protracts, and two scraping blade elasticity are opened and are an angle, on about 33～36 ° of two scraping blade sword is arranged; desirable more sample; after the sampling, because of location fork effect, thin sleeve pipe can only retreat to the location vent and put; the pulling handle; the scraping blade thin sleeve pipe of withdrawing, bead keeps off at thin sleeve opening, and the sampling thing is not contaminated by bead and casing protection on the scraping blade; after the taking-up; pushing handle forward again, scraping blade stretches out sleeve pipe, and the thing of will taking a sample is coated on the slide inspects by ready samples.

Because of this sampler structure is simple, with low cost, easy to operate, the patient is painless, therefore, may replace existing diagnostic branch erasion, becomes convenient, the practical disposable medical appliance of modern hospital a new generation.

Accompanying drawing is embodiment:

Fig. 2 two scraping blades stretch out thin telescopic state

This catcher is by core bar (1), scraping blade (2), and (3) and thin sleeve pipe (4) constitute, and two scraping blades are connected in the core bar front end, not the time spent, stretch out outside the thin sleeve pipe, during use, earlier in the thin sleeve pipe of income, after pushing uterine cavity, stretch out sleeve pipe again, elasticity is opened and is about 35 ° of angles.There is a bead (5) on scraping blade (2) top, and sphere diameter is greater than casing inner diameter.The metric system scale is arranged on the sleeve pipe, can be used for measuring the cavity of uterus degree of depth, the core bar afterbody is one handle (6), transmits strength when scraping extract operation, and there is a pair of location fork (7) in handle the place ahead, and core bar is positioned when two scraping blades open when stretching out thin sleeve pipe just.

During use, earlier scraping blade is taken in the thin sleeve pipe, again catcher is stretched into uterine cavity, sleeve pipe is retreated to the location fork, scraping blade opens, and after the sampling, holds handle, and scraping blade is retracted in the thin sleeve pipe, and bead blocks sleeve opening, takes out the smear censorship.

Claims

1, endometrial cell catcher, constitute by core bar, two scraping blades, bead, location fork and thin sleeve pipes, it is characterized in that two scraping blades are fixed on the core bar top, one angle is arranged between the scraping blade, elasticity is opened, bead is fixed on a scraping blade top, sphere diameter is greater than thin casing inner diameter, thin casing pipe sleeve is in the core bar outside, cover external diameter of pipe and cervical canal caliber adapt, and the metric system scale is arranged on it, and the core bar afterbody is an one handle, the location fork is fixed on the core bar in handle the place ahead, and the length that the core bar front end is pitched in the location is identical with thin sleeve pipe.

2, endometrial cell catcher according to claim 1 is characterized in that there is sword in two scraping blade outsides.
