Abstract

The invention relates to the technical field of medical instruments, in particular to a uterine curettage device for the obstetrical department and aims to solve the technical problem of inconveniencein diameter and length adjustment of existing stainless steel pipes. The uterine curettage device provided for solving the technical problem comprises a hollow tube, a dilator and a length adjustinghead. The dilator is arranged in the hollow tube, one end of the length adjusting head is in movable connection with one end of the dilator, the dilator comprises a rotating shaft, one end of the rotating shaft is in movable connection with one side of the inner wall of the hollow tube, and two sides of the surface of the rotating shaft are fixedly connected with inner wall of two push plates through connecting shafts respectively. By rotation of a rotating block, a threaded annular sheet is enabled to rotate in an annular screw groove, then the push plates gradually extrude adjusting plates,two expansion arc plates can be driven to expand outwards through adjusting shafts, and thus, the integral diameter of the hollow tube can be increased, and an application range can be expanded.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an obstetric curettage device. Background technique [0002] Curettage refers to the operation of scraping the endometrium or the contents of the uterine cavity. Minor surgery often performed in obstetrics and gynecology is one of the methods of induced abortion. There are two types of dilatation and curettage (referred to as curettage) and therapeutic curettage. It has certain risks and complications. [0003] ① Curettage is divided into general curettage and segmental curettage. General diagnosis and curettage, suitable for endocrine abnormalities need to understand the changes of endometrium and the response to sex hormones, whether there is ovulation, whether there is tuberculosis and other diseases. Segmented diagnosis and curettage refers to scraping the cervical canal first and then curettage of the uterine cavity, and sending the scrapings to pathological exam...
