Description

Sampler

Technical Field

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

Background

Uterine cavity, the space of the uterus, is also called uterus. The uterus is positioned in the center of the bone pelvic cavity, and the normal uterus presents a forward-leaning forward-bending position in the pelvic cavity. The uterus morphology of the non-inoculated adult females is in the shape of an inverted pear, and is slightly flattened in front and back. In gynecology, endometrial pathological examination is a basic standard for diagnosis and treatment of endometrial related diseases, but the traditional doctor-blading and hysteroscopy processes are painful and expensive, so that a uterine cavity sampler is often used in a hospital for uterine cavity germ test.

The utility model discloses a gynecological reproduction clinical uterine cavity sampler, which comprises a rear barrel, a front barrel and a connecting pipe arranged between the rear barrel and the front barrel, wherein a straight rod is inserted in the rear barrel, the front end of the straight rod extends towards the inside of the front barrel, the front end of the straight rod is provided with a screw rod, the front end of the screw rod is provided with a rotating block, the rear end of the straight rod is provided with a fixing rod, and the tail end of the fixing rod is provided with a handle.

The above patent scrapes the uterine cavity sample through the scraper, however, the scraping depth of the scraper in the above patent is found to be fixed in clinical application, however, the depth that the focus is in the uterine cavity is different, so the above patent is suitable for scraping samples with different depths.

Disclosure of Invention

The utility model aims to provide a sampler, so as to provide a sampler with adjustable scraping depth of a scraper.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the sampler comprises a handle, wherein the inner wall of the handle is in threaded connection with a hollow straight rod, one end of the straight rod extends out of the handle, and the other end of the straight rod is fixedly sleeved with a rotating block; still include the regulation pole of coaxial swivelling joint with straight-bar inner wall, rotatory piece is along circumferencial direction sliding connection having a plurality of scrapers, adjusts the fixed arc piece that cup joints with every scraper blade butt of pole, and the thickness of arc piece is prolonged anticlockwise and is increased gradually, and the inner wall of handle is equipped with the ring channel that holds a plurality of scrapers.

The working principle of the utility model is as follows: this scheme is used before rotatory piece is located the handle inside, a plurality of scrapers are located the ring channel, at this moment one hold tightly the straight-bar, confirm the scraper blade extension length according to scraping the degree of depth, because a plurality of scrapers all with rotatory piece sliding connection, and adjust pole and straight-bar coaxial rotation are connected, and with the fixed cup joint of regulation pole again of the arc piece of every scraper blade butt, and the thickness of arc piece is prolonged anticlockwise and is increased gradually, then the regulation pole of rotating clockwise of another hand, it drives a plurality of arc pieces simultaneously and rotates clockwise, utilize arc piece thickness variation to release the scraper blade outside the rotatory piece gradually, make the scraper blade adjust suitable scraping degree of depth.

At the moment, the handle is inserted into the uterine cavity, then the straight rod is rotated, the straight rod is continuously screwed in to enable the rotating block and the plurality of scrapers to extend out of the handle, the straight rod is continuously rotated to enable the plurality of scrapers to finish sampling, then the straight rod is reversely rotated to enable the rotating block and the plurality of scrapers to retract into the handle, and the handle is pulled out to finish sampling.

The utility model has the beneficial effects that: compared with the prior art, the scheme adjusts the extension length of the scraping plate by rotating the adjusting rod, so that the purpose of adjusting the depth of the scraping plate to scrape the sample is achieved, and the practicality and the adaptability are stronger.

Further, the handle comprises a first connecting rod and a second connecting rod, a corrugated pipe is fixedly sleeved between the first connecting rod and the second connecting rod, and the straight rod is coaxially connected with the second connecting rod through threads. Because the corrugated pipe can be bent at will, the corrugated pipe is sleeved between the first connecting rod and the second connecting rod, and the angle of the first connecting rod can be adjusted at any time, so that the second connecting rod can conveniently and smoothly extend into the uterine cavity.

Further, the handle is provided with a tapered end. The conical end is convenient to insert into the uterine cavity, and the uncomfortable feeling is relieved.

Further, a spring is fixedly arranged between the scraping plate and the rotating block. Under the spring setting, the spring stretches when the arc piece outwards extrudes the scraper blade, and when the arc piece does not extrude the scraper blade, the spring resumes and makes the scraper blade get back to initial position.

Further, the straight rod and the handle are sleeved with rubber sleeves. The rubber sleeve plays a role in increasing friction force, and is convenient to grip the handle and the straight rod.

Further, one end of the adjusting rod far away from the rotating block extends out of the handle and the straight rod. The setting is convenient to rotate the adjusting rod.
