Abstract

A probe endometrium adsorber comprises an external casing and an inside pull rod. The front end of the external tube is provided with a spherical smooth seal while the other end is a soft tube, and the side wall near the front end is provided with via holes; the front end of the inside pull rod is a little bit curling and is also provided with a seal head which slides and seals with the inner wall of the external tube. The rod meter is caved with length indicator, and the back end of the rod meter is provided with a handle; the external casing and the inside pull rod can tone with each other with sealing and sliding. Since the external tube and the inside pull rod are both made of plastic, the utility model is easy to be plugged into the vagina and will not injure the vagina. When the vagina sounding is finished, the inside pull rod will be taken out of the vagina if being pulled, so the utility model is very convenient and safe.

Description

Probe endometrium adsorber

This utility model relates to department of obstetrics and gynecology pathology censored sample device.

In present national women's gynaecopathia, the Uterine myomas rate is higher, and hysteromyoma is easy to malignant change as can not in time finding.Therefore, check in time that early discovery and treatment in time are very important, help thorough healing.

Annual gynecologial examination for early discovery hysteromyoma and other gynaecopathias and treatment in time, is very important to the healthy of women.At present, the common method that gynecologial examination is done by domestic hospital is to extract endometrial juice from the uterus, then, endometrial juice is carried out the pathologic finding chemical examination.Do the sampling process of endometrial secretion liquid pathologic finding: the first step is to insert from vaginal orifice with intra-uterine dilator to expand the palace, makes vaginal orifice and cervical dilatation.The probe made from metal material stretches into intrauterine afterwards, surveys the uterus degree of depth and sampling.Sampling is to stretch into intrauterine with curet, scrapes the juice of getting the uterus inwall, takes out then; Be placed on the microscope slide scraping the material of getting, carry out pathologic finding.In order to guarantee the reliable and accurate of pathologic finding, so carry out multidraw on the wall in uterus.Because the curet head is less, need repeatedly enter repeatedly intrauterine and scrape and get uterus inwall juice, can finish the sampling of inwall many places, uterus.The sampling of use curet, the shortcoming that certainly exists is:

1. the women has sense of discomfort and pain when doing sampling.

2. the part apparatus repeated use of need sterilizing easily causes infection, and troublesome poeration.

3. uterine probe is that metal material is made, has improper use promptly easily the women uterus to be produced damage even causes perforation of uterus massive hemorrhage slightly.

The purpose of this utility model is, designs and provide a kind of probe endometrium adsorber, to alleviate the misery of women when doing pathologic finding, avoids the injury of examination apparatus to the uterus, and once finishes uterus depth sounding and pathology sampling.

For achieving the above object, this utility model adopts following design:

This probe endometrium adsorber is made of trocar sheath and draw-in bar two parts; Described trocar sheath is that a front end is provided with that sphere shape is smooth seals, and the rear end is open pipe, has through hole on its front end sidewall; Described draw-in bar, its external diameter is slightly smaller than outer casing internal diameter, its length is a bit larger tham trocar sheath length, leading section at draw-in bar is provided with and can be sealed sliding seal head movingly with outer sleeve inner wall, long on the draw-in bar surface to being carved with length mark, the other end at draw-in bar is provided with the handle of external diameter greater than the trocar sheath external diameter, and draw-in bar becomes with trocar sheath to insert and is slidingly matched.In order to make this probe endometrium adsorber end can extend the uterus different parts, trocar sheath should have the front portion of certain flexibility draw-in bar that one bending than small curve is then arranged.

Use advantage for more clearly describing design of the present utility model with it, as follows in conjunction with most preferred embodiment and description of drawings now:

The structural representation of accompanying drawing-probe endometrium adsorber.

I have made a probe endometrium adsorber by above-mentioned design with transparent plastic.During use, as long as insert draw-in bar 2 in the trocar sheaths 1 and be pushed into the top, then by the sampling operation sequence sampler transvaginal insertion uterus, can predict the uterus degree of depth according to draw-in bar institute reading word.During sampling, only need arrest trocar sheath also pulls back the handle 22 of draw-in bar 2, because of the seal head 21 of interior trombone slide 2 ends moves synchronously, the inner chamber end of trocar sheath 1 produces negative pressure, so can be with the perforate 11 suction trocar sheath inner chambers of endometrium liquid from the trocar sheath proximal, side wall.Be shifted and rotation by extracting of sampler, can finish multidraw each position, uterus.Because of sampler is that front end and surface are very smooth with gentle plastic production, can not damage, and sampling and uterus depth measurement can once finish uterus or vaginal membranes, significantly reduced the misery of being examined the women.Because this sampler is easy to manufacture, cheap, should make disposable sampler, has avoided cross infection.

Claims

1, a kind of probe endometrium adsorber, it is characterized in that: it is made of trocar sheath and draw-in bar two parts; Described trocar sheath is that a front end has sphere shape smoothly to seal, the rear end is open pipe, has through hole on its front end sidewall; Described draw-in bar, its external diameter is slightly smaller than the trocar sheath internal diameter, its length is a bit larger tham trocar sheath length, front end at draw-in bar is provided with and can be sealed sliding seal head movingly with outer sleeve inner wall, long to being carved with length mark on draw-in bar surface, be provided with the handle of external diameter at the other end of draw-in bar greater than the trocar sheath external diameter; Draw-in bar becomes with trocar sheath to insert and is slidingly matched.

2, according to the described probe endometrium of claim 1 adsorber, it is characterized in that described trocar sheath has certain flexibility, then there is a bending than small curve the front portion of draw-in bar.
