Suction and curettage device for obstetrical operation

Abstract

The invention relates to the technical field of obstetrical auxiliary instruments, and concretely relates to a suction and curettage device for obstetrical surgery. The device comprises a stretching tube, the tube wall of the stretching tube is of a cavity structure, the stretching tube is of a structure with a wide upper part and a narrow lower part, a circular through hole is formed in the side surface of the narrower end of the stretching tube, and a negative pressure tube is arranged at the circular through hole in a penetrating manner; one end of the negative pressure pipe is connected with a negative pressure machine, an adjusting mechanism matched with the negative pressure pipe is arranged at the position, at the round through hole, of the bottom end of the negative pressure pipe and comprises a bottom plate, and a fixed arc piece and a penetrating arc piece which are matched with each other are fixedly installed at the top end of the bottom plate. After natural delivery, a woman can intuitively observe the internal condition when sucking and scraping are carried out in the uterus, so that the safety in the wiping process is conveniently ensured, and the export of some retentate is ensured; and through the arrangement of the adjusting mechanism, the injected cleaning liquid medicine can be sucked out under manual control, and the sucking and scraping efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of obstetric auxiliary instruments, in particular to a suction curette for obstetric surgery. Background technique [0002] After the woman gives birth, after the fetus and its appendages leave the uterus, the medical staff usually wipe the uterine cavity repeatedly with dry gauze. The basal layer of the endometrium is easily damaged to varying degrees; in addition, during the process of taking out the gauze, blood often flows into the surgical field, which leads to various complications and brings greater loss and pain to the puerpera and her family. We propose a suction curette for obstetric surgery. Contents of the invention [0003] The purpose of the present invention is to solve the shortcoming existing in the prior art, and propose a kind of suction scraper for obstetrical operation. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [...
