Background

Induced abortion surgery refers to the surgical approach to terminate pregnancy. The artificial abortion operation usually includes negative pressure suction and forceps-scraping, and the embryo tissue in uterus is sucked out by using a suction tube or taken out by using surgical instruments such as oval forceps, so as to terminate the pregnancy. Thus, the heart of the human flow surgery is two-fold: firstly, embryo tissues need to be cleaned, so that incomplete abortion is prevented; and secondly, accidental injury to the uterus in the operation process, such as accidental perforation of the uterus and the like, is prevented.

Since the induced abortion operation needs to be performed in utero, the conventional induced abortion operation often depends on the experience and feeling of a doctor, and thus various complications are liable to occur. With the development of endoscopic techniques, more and more operations are being performed under endoscopic surgery, wherein the induced abortion surgery is also beginning to be performed gradually under endoscopic direct vision.

In the operation process, along with the scraping of embryo, a large amount of bloody water can be produced in utero, but a large amount of electronic components are arranged in the direct-view artificial abortion device, if the electronic components are not isolated and protected, the bloody water enters an electronic and circuit system, equipment is very easy to break down, and therefore operation accidents can occur due to the fact that the equipment cannot be observed in time in the operation process. Therefore, the existing direct-view artificial abortion device needs to be improved to ensure that the blood or tissue fluid generated in the operation process does not influence the normal operation of electronic components in the device, and the observation of the operation process is not influenced.
