Abstract

The utility model discloses a disposable endometrium sampler which belongs to the technical field of the medical appliance. The disposable endometrium sampler is composed of a sampling tube, a piston and a push-pull rod, and is characterized in that the front end of the sampling tube is smooth, scales are marked on the outer wall of the sampling tube, the interior of the sampling tube is glidingly and hermetically connected with the piston with the push-pull rod, sampling holes communicating with the inner cavity of the sampling tube are respectively arranged at the front end of the sampling tube and on the side wall of the front end, and salient points showing the direction of the sampling holes are arranged on the outer wall of the rear end of the sampling tube, and an annular heave used for preventing the piston from dislocation is arranged on the inner wall of the rear end. The disposable endometrium sampler has the advantages that the outside diameter of the sampling tube is small, and the sampling tube can directly enter into the uterine cavity of a patient without dilating the cervix of uterus, thereby greatly reducing the pain of the patient; the scales marked on the sampling tube and the salient points marked on the outer wall of the rear end facilitate a doctor to master the insertion depth and the sampling hole direction, and the sampling tube can arbitrarily rotate, advance and retreat according to the demands, thereby the sample operation can be carried out in any position, and the samples are full and precise.

Description

Disposable endometrium sampler

Technical field

This utility model belongs to technical field of medical instruments, the disposable endometrium sampler that specifically a kind of department of obstetrics and gynecology are used.

Background technology

At present, symptoms such as infertile, the vaginal hemorrhage in the gynaecopathia need be taked to examine to scrape, promptly getting tissue with metallic weapon in the uterine cavity conducts a survey, examine that to scrape be the process of a misery, and because apparatus is the sharp keen property of metal article mostly, so the danger of the perforation of uterus is arranged, metallic weapon uses repeatedly and is easy to generate cross infection, expands the palace and also makes the patient very painful.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of softness lubricated, can reduce patient suffering's disposable endometrium sampler.

The purpose of this utility model is achieved in that this disposable endometrium sampler is made up of probe tube, piston, push-pull bar, the probe tube front end that outer wall is provided with scale mark is slick and sly shape, slides within is being tightly connected and is having the piston of push-pull bar, on probe tube top and front end side wall, have the thief hole that communicates with the probe tube inner chamber, probe tube rear end outer wall is provided with the salient point that shows the thief hole direction, and the rear end inwall is provided with the annular protrusion that prevents the piston dislocation.Integral material adopts softish non-toxic plastic to make, and is nontoxic to human body.

During use, probe tube directly is inserted in the cervix uteri, the pulling push-pull bar drives piston and moves, thereby intracervical tissue substance is drawn in the probe tube by thief hole.Probe tube can rotate arbitrarily as required, advance and retreat, and at each position sample, sampling comprehensively accurately.

Advantage of the present utility model: the probe tube external diameter is little, need not expand the palace and just can directly enter in patient's uterine cavity, alleviates patient's misery greatly; Salient point labelling on scale mark on the probe tube and the rear end outer wall is convenient to the direction that the doctor grasps insertion depth and thief hole, and probe tube can rotate arbitrarily as required, advance and retreat, and at each position sample, sampling comprehensively accurately.
