Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a gynecological curettage device. Background Art

[0002] Curettage refers to a surgical procedure to scrape or collect the endometrium or uterine cavity contents. It is mainly used in artificial abortion, diagnosis, etc. Clinically, it is often divided into diagnostic curettage and therapeutic curettage. Therapeutic curettage is further divided into suction curettage and forceps curettage. Among them, forceps curettage refers to the use of oval forceps to clamp the contents of the uterine cavity and then scrape them. When using forceps curettage, a curettage device with a curette at the end is often used.

[0003] In the prior art, there is a gynecological treatment curettage device with announcement number CN 217138190 U, which includes a ring-shaped curette, an insertion tube, and a collecting tube connected in sequence; the inner ring side of the ring-shaped curette is provided with a concave collecting groove; the inner cavity of the insertion tube is provided with a collecting hose, one end of the collecting hose is connected to the collecting groove, and the other end of the collecting hose passes through the end of the collecting tube away from the insertion tube. Through the ring-shaped curette with the concave collecting groove, the material to be scraped out of the inner wall of the uterus or the uterine cavity by the ring-shaped curette can flow into the collecting tube along the collecting groove on the inner ring side of the ring-shaped curette, thereby reducing the damage that may be caused by scraping with forceps and alleviating the workload of subsequent cleaning.

[0004] However, the existing curettage device can perform treatment operations on patients well when in use, and can conveniently absorb and collect scraped impurities through the hose, but the use angle of the ring curette is fixed, and medical staff need to manually adjust the use angle of the ring curette. The automatic control force of the ring curette angle adjustment is not very effective, and when the use angle of the ring curette is automatically adjusted, the effect of synchronous patting and loosening the impurities sucked in the suction tube is not good. When the suction tube is used for a long time, impurities are easily blocked, affecting the unblocking performance of the suction tube. The scraped impurities can only be absorbed and collected through a single suction channel. The drive conversion between suction and blowing is poor, which reduces the pre-loosening of impurities in the patient's scraped area, increases the difficulty of impurity scraping, and affects the efficiency of scraping treatment. It does not meet people's use needs. For this reason, we propose a gynecological curettage device. Summary of the Invention

[0005] In order to solve the problems mentioned in the above background, the present invention provides a gynecological curettage device to solve the problem that the automatic control force for adjusting the angle of the ring scraper proposed in the above background technology is not effective, and when the use angle of the ring scraper is automatically adjusted, the synchronous patting and loosening effect of the impurities sucked in the suction tube is not good.
