Description

Uterine curettage device for obstetrical department

Technical Field

The invention relates to the technical field of medical appliance rings, in particular to a uterine curettage device for obstetrical department.

Background

The uterine curettage operation is an operation for scraping tissues or collecting endometrial tissues in the uterus of a patient, particularly for removing residual tissues after manual operation and taking out and analyzing pathological tissues of uterine diseases, uterine curettage is often a necessary operation, which not only can help doctors to diagnose diseases of the patient, but also is a relatively direct and reliable treatment means for the patient, particularly for abortion operation, residual tissues in the uterus are not removed in time, gynecological inflammation is easily caused, the fertility of women can be further influenced, the existing uterine curettage operation is generally divided into two steps, the first step is to expand the uterine cervix, so that the requirement of the surgical instrument can be conveniently stretched into the uterine cervix, and the vagina can be expanded together usually, so that medical staff can be operated directly and conveniently, even sometimes, the uterus of a patient needs to be clamped by an operating forceps, so that the uterus can not be greatly displaced to influence the normal operation of the operation during the uterine curettage operation; the second step is to stretch the uterine curettage device into the uterus to curette the tissue of the uterus of the patient, however, due to the factors such as the residual tissue in the uterus or the number of samples to be curetted, the traditional uterine curettage operation usually needs to repeatedly stretch the uterine curettage device into the uterus for multiple times to perform tissue transplantation, so that the cervix of the patient is repeatedly curetted during the operation, and the tissue in the uterus is sensitive and tender, so that after the subsequent anesthesia effect is lost, the lower abdomen of the patient has obvious pain feeling and even lasts for a long time, which is the postoperative adverse reaction caused by certain damage to the tissue in the uterus and the vagina due to repeated reciprocating operation, and one of the reasons of the sequelae is that the surgical device stretches into the vagina or the uterus during the operation of the uterine curettage operation, so that the device can scrape the internal tissue of the patient, Mucous membrane, and the tissue injury caused by scraping and dragging.

As is well known, different female patients have different physiological characteristics and different physiological structures, the existing operation is usually a set of procedural or textbook-type operation mode, which also results in different patients, the treatment experience after uterine curettage is different, even some patients suffer from serious psychological diseases (such as psychological fear), and along with the continuous development of medical level, humanized and customized treatment concepts are continuously popularized, the requirements on medical auxiliary instruments are higher and higher, how to improve the traditional surgical instruments also meets the requirements of humanized medical concepts, and the important technical problem which needs to be solved urgently by the personnel in the field is also solved.
