Cervical collector

Technical Field

The utility model relates to the technical field of medical equipment, more specifically say, relate to a cervical collector.

Background

In recent years, with the rapid development of economy in China, the working pressure of women is gradually increased, and the probability of endometrial cancer of the women is obviously increased due to the change of dietary structure. The health of women is concerned, and the early detection and early treatment of endometrial cancer are particularly important for sampling and detecting the endometrium. Clinically, the endometrium is sampled mainly by a curette, but the method is a nonrepeatable traumatic diagnosis method, has complicated operation process and high cost, and brings great pain to patients.

In order to solve the above problems, many improvements have been made in recent years by the related art, such as chinese patent number ZL201620244735.3, publication date 2016, 9, 14, and utility model name: a cervix uteri sampler, the application relates to a cervix uteri sampler, comprising a shell, a fixed rod which is arranged in the shell in a penetrating way, wherein the two ends of the fixed rod are respectively provided with a first fixed head and a second fixed head; the lower end of the film scraping pipe is sleeved on the first fixing head, the upper end of the film scraping pipe is sleeved on the sliding pipe, the lower end of the sliding pipe protrudes out of the lower end of the shell, the sliding pipe is sleeved with a spring, the sliding pipe is provided with a limiting wing for limiting the spring to pass through, the spring is arranged between the limiting wing and the upper end of the lower shell, and the push button can drive the film scraping pipe to open for sampling. The application has the advantages that sampling is accurate, convenient and fast, but the cervical sampler is complex in structure and multiple in parts, the opening range of the film scraping tube is fixed under the action of the push button, flexible adjustment cannot be achieved, the use risk is increased, and the structure is to be further simplified; and also increases the cost of the sampler.

Detailed Description

For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings and examples.

Examples

Referring to fig. 1 to 3, the cervical collector of this embodiment, including core bar 7 and scraping strip 2, scraping strip 2 both ends difference fixedly connected with end 1 and connecting block 3, end 1 sets up the top at core bar 7, end 1 can fix and set up on core bar 7 also can detachably install on core bar 7, and end 1 surface is smooth, be convenient for reduce stimulation and injury to the human body when it gets into the human body, can not cause harmful damage such as scratch to the human body, the afterbody of core bar 7 is equipped with handle 6, the afterbody and the handle 6 of core bar 7 preferably adopt threaded connection, with the help of handle 6, the user can conveniently hand, and handle 6 and core bar 7 threaded connection, be favorable to the assembly of product, reduce the production degree of difficulty and cost of manufacture. The sleeve 4 is sleeved on the core rod 7, the connecting block 3 is connected with the top end of the sleeve 4, and the side face, far away from the connecting block 3, of one end of the sleeve 4 is provided with a push button 5 used for driving the sleeve 4 to move so that the scraping strip 2 deforms. The scraping bar 2 is deformed under the driving of the push button 5, so that the scraping bar 2 is narrow when entering a human body, the scraping bar 2 is widened in width during sampling, the width of the scraping bar 2 is narrowed again after the scraping bar is taken out from the human body, the scraping bar 2 is convenient to adjust in opening amplitude, the scraping bar is convenient to take out and is small in harm to the human body, the cervical sampler is simplified only by being realized under the action of the push button 5, and the manufacturing cost is reduced.

Referring to fig. 1 to 3, in this embodiment, the connecting block 3 is sleeved on the core rod 7, and the sleeve 4 is connected to the connecting block 3 through the threads on the connecting block 3, so that the connecting block 3 can be driven to move back and forth only by the push button 5, and the scraping bar 2 is deformed, the opening radius thereof is changed accordingly, and the operation is simple and effective. Be provided with on the handle 6 and be used for supplying to push away the recess that button 5 removed, the recess has and is used for carrying out the screens to pushing away button 5 screens hole, and the recess has played the guide effect to the route that pushes away the button, and the screens hole is favorable to fixing after the operation is accomplished for easy operation is firm. Handle 6 is handed to the operator, when promoting to push away button 5 at the recess internal motion, push away button 5 and drive connecting block 3 of connection on sleeve 4 and carry out the back-and-forth movement, because handle 6 is fixed with core bar 7, thereby core bar 7 keeps motionless, and then end 1 also can not move relatively, connecting block 3 removes the in-process and can change the distance with end 1, thereby scrape strip 2 and can take place deformation, can conveniently pass in and out when scraping strip 2 opens the radius hour, when opening the radius when big, be favorable to acquireing the testing material, easy operation is convenient. Preferentially, scrape strip 2 and can have many, for example 3 ~ 4 between end 1 and connecting block 3 the equipartition to scrape strip 2 and have elastic brush hair, be favorable to scraping the strip sampling more convenient abundant, improve the accuracy that detects.

According to the cervical collector of the embodiment, before entering a human body, the push button 5 is pushed to the rearmost, so that the scraping strip 2 is in an extended state, the opening radius of the push button is minimum, the push button 5 falls into the limiting hole, and the human body can conveniently enter the cervical collector; after entering a human body, when sampling, the push button 5 is pushed forwards along the groove, so that the scraping strip 2 is expanded outwards to realize sampling; after sampling, the push button 5 is pushed to the rearmost, and the scraper bar 2 is taken out of the body when the opening radius is small.

The utility model provides a cervical collector scrapes the strip and takes place deformation under the drive that pushes away the button to the realization is scraped the strip when getting into the human body narrower, and during the sample, the strip of scraping opens the width widen, and the width that makes the strip of scraping follow internal taking out continues to narrow down, and it is convenient to scrape the strip and opens the range regulation, conveniently takes out and just harms for a human body little, only just can realize through the effect that pushes away the button, has simplified the structure of cervical sample thief, has reduced the cost of manufacture.

The present invention and its embodiments have been described above schematically, and the description is not intended to be limiting, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without creatively designing the similar structural modes and embodiments to the technical solutions, they should belong to the protection scope of the present invention.
