Description

Technical Field

[0001] The utility model relates to the technical field of medical tools, in particular to a uterine curette. Background Art

[0002] Curettage is a procedure in which the endometrial tissue is scraped and collected from the uterus. Curettage is a low-risk procedure that can stop bleeding and help diagnose infections, cancer, infertility, and other conditions. Normally, once the patient feels better (usually the same day), she or he can resume normal activities. Vaginal bleeding, lower abdominal cramps, and back pain may persist for several days after the procedure, and painkillers can be taken to relieve the pain. The use of internal tampons is not recommended for several weeks, and sexual intercourse is not recommended for several days. During the operation, general or local anesthesia is used; the cervix is ​​then exposed with a vaginal speculum; the cervix is ​​disinfected; the cervical canal is paralyzed (unconventional); the cervix is ​​dilated with a rod-shaped cervical dilator; a thin metal rod with a curette on the end is inserted into the uterine cavity; the endometrium is scraped out and sent for pathological examination.

[0003] During the operation, medical staff hold a curette and insert it into the patient's body for scraping and sampling. The ends of the curettes currently used are mostly plate-like structures with a slight curvature. When the endometrium is taken out after scraping, the endometrium on the end of the curette is easy to fall off, making sampling inconvenient. In addition, the medical staff needs to push and pull the curette many times during the sampling process, which can easily cause discomfort to the patient, especially during local anesthesia when the patient still has a certain perception.

[0004] Therefore need a kind of uterine curette which is easy to operate and has strong practicality. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a uterine curette, which has the characteristics of convenient operation and strong practicality.

[0006] In order to achieve the above purpose, the utility model proposes the following specific solutions:

[0007] A uterine scraper comprises a cannula, the inner side of which is plugged with a scraper assembly, the scraper assembly comprising a pushing arc plate, a push rod and a scraping arc plate, a push rod is fixedly provided at the inner middle part of the pushing arc plate, the push rod passes through the cannula, a scraping arc plate is fixedly provided on the top surface of the push rod, the upper end of the scraping arc plate is clamped on the end of the cannula, an elastic folding tube is fixedly provided on the side wall edge of the pushing arc plate, and one end of the elastic folding tube is fixedly connected to the side wall of one end of the cannula.

[0008] As an optimal technical solution of a uterine scraper of the utility model, the insertion tube includes an operating tube, a connecting tube and a supporting tube, the elastic folding tube is fixed at one end of the operating tube, the other end of the operating tube is fixedly provided with a connecting tube, one end of the connecting tube is fixedly connected with a supporting tube, and the scraping arc plate is clamped on the inner side of the end of the supporting tube.

[0009] As a preferred technical solution of the uterine curette of the utility model, a support ring is fixedly provided on the inner wall of the support tube, a retaining ring is fixedly provided in the middle of the support ring, and the retaining ring is sleeved on the outer side of the push rod.

[0010] As a preferred technical solution of the uterine curette of the utility model, a fin plate is fixedly provided on the outer wall of one end of the operating tube.

[0011] As a preferred technical solution of the uterine curette of the utility model, the scraping arc plate is made of a flexible material.

[0012] As a preferred technical solution of the uterine curette of the utility model, the elastic folding tube is made of flexible material.

[0013] As a preferred technical solution of the uterine curette of the utility model, the inner diameter of one end of the support tube is larger than the inner diameter of the other end of the support tube.

[0014] As a preferred technical solution of the uterine curette of the utility model, the inner size of the connecting tube is matched with the size of the push rod.

[0015] Compared with the existing technology, the utility model has the following beneficial effects:

[0016] The utility model provides an intubation tube, a scraper assembly and an elastic folding tube. The scraper assembly is plugged into the inner side of the intubation tube. The scraping arc plate at the end of the scraper assembly is clamped into the inner side of one end of the intubation tube. The other end of the scraper assembly is connected to the elastic folding tube by pushing the arc plate, and one end of the elastic folding tube is connected to the other end of the intubation tube. When the medical staff operates the tool to scrape the endometrium of the patient, the intubation tube is inserted into the patient's body so that the end is located inside the patient's uterus, and one end is blocked outside the patient's body by the wing plate for limiting, and then the arc plate is pressed to push the arc plate to press The elastic folding tube is retracted to make the push rod move inside the cannula, so that the scraping arc plate at one end of the push rod extends out of the cannula. Then the medical staff tilts the cannula so that the scraping arc plate fits against the inner wall of the patient's uterus. Then the arc plate is released to push the push rod back, so that the scraping arc plate scrapes the patient's endometrium. The scraping arc plate with the endometrium is clamped on the inner side of one end of the cannula to store the scraped endometrium, so as to avoid the endometrium from falling off easily when the cannula is pulled out, thereby improving the convenience of operation.

[0017] Furthermore, by providing an elastic folding tube, medical staff do not need to move the cannula back and forth during the process of scraping the endometrium. The movement of the scraping arc plate is achieved by stretching and compressing the elastic folding tube, which is easy to operate and reduces patient discomfort. BRIEF DESCRIPTION OF THE DRAWINGS
