Hyperelastic basket-type induced abortion device

Abstract

The invention discloses a hyperelastic basket-type induced abortion device which comprises a sheathing canal, a guide wire, a basket and a handle. The guide wire penetrating through the interior of the sheathing canal is divided into a front-end guide wire body and a back-end guide wire body, the handle is connected with the back-end guide wire body, the basket used for removing the pregnant tissue is connected with the front-end guide wire body, and the basket comprises a plurality of wire rings and is made of hyperelastic shape memory alloy. According to the hyperelastic basket-type induced abortion device, the structural design is reasonable, the purpose of pregnancy termination with the minimum hurt can be achieved, the good biocompatibility and nontoxicity are achieved, infection and hurt to the uterine cavity wall of the uterus and uterine perforation cannot be caused, the pregnant tissue is completely taken out, and pain of an operation acceptor is reduced.

Description

technical field [0001] The invention relates to the field of biomedical devices, in particular to a superelastic basket type artificial flow device. Background technique [0002] At present, major hospitals add anesthetics to the negative pressure suction surgery, which is the so-called painless abortion. Although it solves the pain and mental stress of the operation, it does not solve the various problems of the negative pressure suction surgery, such as the need for Negative pressure and dilation of the cervix; the negative pressure suction tube is a hard tube. After dilating the cervix, the hard tube can be inserted into the uterine cavity to suck and scrape the pregnancy. The hard tube cannot conform to the position and curvature of the uterus changes, uterine perforation, etc. Over the years, in order to improve the safety and effectiveness of surgery, and reduce surgical pain and complications, domestic and foreign scholars have conducted various researches and improv...

[0002] At present, major hospitals add anesthetics to the negative pressure suction surgery, which is the so-called painless abortion. Although it solves the pain and mental stress of the operation, it does not solve the various problems of the negative pressure suction surgery, such as the need for Negative pressure and dilation of the cervix; the negative pressure suction tube is a hard tube. After dilating the cervix, the hard tube can be inserted into the uterine cavity to suck and scrape the pregnancy. The hard tube cannot conform to the position and curvature of the uterus changes, uterine perforation, etc.

Over the years, in order to improve the safety and effectiveness of surgery, and reduce surgical pain and complications, domestic and foreign scholars have conducted various researches and improvements on it, but they have not deviated from the basic principle of negative pressure suction, so they have not been Fundamentally avoid a series of side effects and complications caused by negative pressure suction
