Description

Direct view of the flow and curettage system

Technical field

The invention relates to an endoscopic surgical instrument, in particular to a direct vision abortion and curettage system with a protective mechanism in endoscopic surgery.

Background technique

Abortion surgery refers to the termination of pregnancy by surgical methods. Abortion surgery methods usually include negative pressure suction and forceps curettage. The embryonic tissue in the uterus is sucked out with a straw or the embryo tissue in the uterus is taken out with surgical instruments such as oval forceps to achieve the purpose of terminating pregnancy. Therefore, the core of abortion surgery lies in two aspects: one is that the embryonic tissue needs to be removed to prevent incomplete abortion; the other is to prevent accidental damage to the uterus during the operation, such as accidental perforation of the uterus.

Because abortion surgery requires operations in the uterus, traditional abortion surgery often relies on the experience and feeling of the doctor, so various complications are prone to occur. With the development of laparoscopic technology, more and more operations are completed under laparoscopic surgery, and abortion operations are gradually being performed under laparoscopic direct vision.

In the existing direct-view flow device, the lens module is placed at the forefront of the direct-view flow device. The tube body of the flow tube mostly adopts a double-cavity structure, and one cavity is used to install the circuit to collect the image data collected by the lens module. It is transmitted to the host and displayed on the display after processing. The other cavity is used as a negative pressure suction tube, one end is connected to the negative pressure source, and the other end is open at the front end of the flow tube.

During the operation of the existing direct-viewing flow device, the lens usually can only observe the local state in a small area around the surgical site. If the gestational sac is large or the implantation bed is closer to the corner, omissions may occur during the observation process, resulting in The abortion operation is not complete, so it is necessary to improve the existing direct-view abortion device.
