Direct-vision induced abortion uterine curettage device and system

Abstract

The invention discloses a direct-vision induced abortion uterine curettage device. The device comprises a uterine curettage mechanism, an observation mechanism, a circuit, a negative pressure suctionmechanism and an operation rod. A curettage device of the uterine curettage mechanism is arranged at the front ends of the operation rod and a camera and located in the view of the camera. According to the technical scheme that the camera is arranged on the rear portion, the curettage device is completely located in the view of the camera, the whole operation process can be visible, and no observation dead zone exists. Meanwhile, the curettage device cannot have operation dead corners due to shielding generated by the height of a lens module, embryo tissue can be completely removed when implanted at any position of the uterus, especially for the implantation position near the fallopian tube orifice, namely the bottom of the uterus, the curettage device can easily remove the embryo tissue,and the clinical use process is safer and more efficient. A direct-vision induced abortion uterine curettage system comprises the direct-vision induced abortion uterine curettage device, operation canbe carried out under real-time display of a display system, and the induced abortion operation process is very accurate, safe and efficient.

Description

technical field [0001] The invention relates to an endoscopic surgical instrument, in particular to a curettage device and system for direct-viewing abortion in endoscopic surgery. Background technique [0002] Abortion refers to the use of surgical methods to terminate pregnancy. Abortion surgery methods usually include negative pressure aspiration and forceps curettage. The embryonic tissue in the uterus is sucked out with a straw or the embryonic 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 cleaned up to prevent incomplete abortion; the other is to prevent accidental damage to the uterus during the operation, such as accidental perforation of the uterus. [0003] Because the abortion operation needs to be operated in the uterus, the traditional abortion operation often relies on the ...

Problems solved by technology

[0004] In the direct-viewing flow device of the prior art, the lens module is placed at the front end of the direct-viewing flow device. After finding the embryo implantation tissue through the camera lens, the negative pressure suction port located at the rear end of the camera is used to attract the implanted embryo tissue, and then The detachment of the implanted embryo is completed by repeated insertion and insertion of the artificial flow tube. Because the camera is located at the front end, the specific process of the detachment of the embryo from the implantation site is still invisible during the clinical operation of the direct-viewing artificial abortion device of the prior art. Clinically, there is a risk of incomplete abortion

In addition, since the lens module itself has a certain height, there is a distance of at least 8mm from the negative pressure suction port. Therefore, for the implanted embryos near the entrance of the fallopian tube, that is, near the fundus of the uterus, it is difficult for the direct-viewing artificial abortion device of the prior art. In addition, if the insertion depth of the artificial flow tube is too large, it is easy to cause accidental damage to the fundus of the uterus, and even cause serious consequences of uterine perforation
