Description

Technical Field

[0001] The utility model belongs to the technical field of medical care, and in particular relates to an extraction device for endometrial diagnosis. Background Art

[0002] Endometrial diagnosis is an important diagnostic method in the field of gynecology, which is used to detect endometrial pathological conditions, such as ectopic endometrial tissue, polyps, polypoid changes, endometrial hyperplasia, endometriosis, etc. Traditional endometrial diagnosis is often performed using methods such as endometrial tissue scraping or endometrial biopsy, but there are some shortcomings, such as the possibility of causing pain and bleeding, and irritation to the endometrium during the operation.

[0003] At present, a series of problems are often faced during gynecological examinations and sampling. Traditional sampling methods may cause the sampling port to scrape the inner wall of the uterus, which may touch the symptomatic area of ​​ulceration or punctate lesions on the inner wall of the uterus, and then cause adverse reactions such as pain in patients. Traditional endometrial diagnostic methods may cause patients to suffer from adverse reactions such as pain and bleeding, affecting the patient's comfort and treatment compliance. In addition, stimulation of the endometrium during the operation may cause a certain degree of damage, affecting the accuracy of the diagnostic results. In addition, during the sampling process, if there is no effective positioning and control, it may cause sampling deviation, resulting in insufficient local sample collection, thus affecting the accuracy of the sampling results.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0018] chute;

[0019] The slide groove is arc-shaped and is opened on the inner wall of the tail pipe sleeve, and the slide groove is connected with the inner wall of the second groove;

[0020] Support seat;

[0021] Positioning pins;

[0023] The positioning pin is fixedly connected to the arc-shaped side wall of the support seat, and the positioning pin is slidably arranged on the inner wall of the second groove and / or the sliding slot.

[0024] Preferably, the end and side wall of the tail sleeve are respectively provided with an end clamping edge and a side clamping edge;

[0025] The inner wall and the side wall of the end pipe sleeve are respectively provided with an end clamping groove and a side clamping groove;

[0026] The end clamping edge and the side clamping edge are respectively sealed and fitted with the end clamping groove and the side clamping groove.

[0027] Preferably, an opening is provided on the surface of the tail tube sleeve for the sampling head to separate the sample.

[0028] Preferably, the sampling head comprises a connecting sleeve penetrating and fixed on the surface of the sampling core rod, the surface of the connecting sleeve is provided with a tough plate, and the surface of the tough plate is fixedly connected with a sealing seat which is sealed and fitted with the sampling port;

[0029] The surface of the connecting sleeve is provided with sampling fluff, and the sampling fluff slides on the inner wall of the first groove;

When sampling, the sampling core rod is rotated, so that under the action of a large torque, the sealing seat is deformed and slides out of the sampling port, and is in a deformed state and fits the inner wall of the shell. Under continuous rotation, the sampling villi are rotated and slide into the sampling port, so that the villi are slightly scraped when they fit the inner wall of the uterus, and the body fluid sample can be stored in the villi. Then, the sampling core rod is rotated to reset the sealing seat, and the villi are located in the first groove to complete the sampling. The sampling process is gentle, and the sampling port is sealed to prevent mixed body fluids such as the urethra from entering when inserted into the uterus, thereby ensuring the accuracy of the sampling position, and the sealing seat fits the inner wall of the uterus without any depression to cause scraping, which can greatly reduce the damage to the existing diseases of the inner wall of the uterus.

[0036] During use, when the sampling core rod rotates, it rotates with the support seat and the retaining head on the surface. The support seat slides in the slide groove with the positioning pin on the surface, so that the support seat and the retaining head rotate under the support. If the sampling fluff is not moved to the designated sampling position to rotate the sampling core rod, the positioning pin and the slide groove are in a misaligned state, making it unable to rotate, so that it can self-lock under irregular operation, and in the state of being able to rotate, it can ensure sufficient scraping of the designated area and ensure the accuracy of the sampling process.
