Description

Direct-vision induced abortion uterine curettage device and system

Technical Field

The invention relates to an endoscopic surgical instrument, in particular to a direct-vision induced abortion uterine curettage device and a system used in endoscopic surgery.

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.

The direct-vision induced abortion device in the prior art, the lens module is arranged at the foremost end of the direct-vision induced abortion device, embryo implantation tissues are found through the camera lens, the embryo tissues of the implantation bed are sucked through the negative pressure suction port at the rear end of the camera, and then the implantation embryos are stripped through repeated drawing and inserting of the induced abortion tube. In addition, because the lens module has a certain height, and there is at least 8 mm's distance to between the negative pressure suction opening, consequently, to the implantation embryo near oviduct entry, near the uterus bottom, the direct-view abortion device of prior art is difficult to clear away, and if the depth of inserting of taking out of people's flow tube was too big, easily caused unexpected damage to the uterus bottom, even caused the perforation of uterus's serious consequence.

Therefore, the applicant further improves the existing direct-view abortion device in the patent application "direct-view abortion uterine curettage device and system" (application numbers: 201910612451.3, 201921057784.6), and places the cameras behind the curettage device to ensure that the embryos can be seen from the whole separation process of the implantation position, but in the prior art, the embryos are shot and observed by one camera, and the angle of view of each camera is limited, so that the cameras cannot be observed in the area beyond the field of view, and in order to solve the problem of limitation of the shooting area of a single camera, the applicant further improves the direct-view abortion device.

The images and videos observed by the camera 22-1 in the light field of theillumination module 21 are processed by thesignal processing module 23 and then output by thecircuit 3.

The negativepressure suction mechanism 4 includes asuction inlet 41, asuction outlet 42, and asuction passage 43; theinlet 41 is provided at the front end of theoperation lever 5, thesuction outlet 42 of the negativepressure suction mechanism 4 is provided at the rear end of theoperation lever 5, and thesuction passage 43 is provided in theoperation lever 5.

Ahandle 52 is arranged at the rear end 5-2 of the operatingrod 5, and auterine curettage mechanism 1 and anobservation mechanism 2 are arranged at the front end 5-1 of the operatingrod 5; the tube body 5-3 of the operatingrod 5 contains thecircuit 3 and the negativepressure suction mechanism 4.

In this embodiment, the camera 22-1 of thelens module 22 is disposed at the rear end of thecurettage device 11, and thecurettage device 11 is located in the visual field of the camera 22-1. The technical scheme that the camera 22-1 is arranged at the rear can ensure that thecurettage device 11 is completely positioned in the visual field range of the camera 22-1, and because the observation angle of the camera 22-1 faces the front of an operation area, an observation blind area cannot exist in the process, and accidental injuries to the uterus and accessories caused by untimely observation are avoided. Meanwhile, thecurettage device 11 is positioned in front of the camera 22-1, so that thecurettage device 11 does not have an operation dead angle due to shielding generated by the height of thelens module 22, embryo tissues can be completely removed from the implantation at any position of the uterus, especially for the implantation position near the oviduct orifice, namely the uterine fundus, thecurettage device 11 can also easily remove the embryo tissues, the incomplete human flow condition can not occur in the operation process, and the cleaning is completed under direct vision, so that the accidental injury of the uterine fundus due to overlarge operation action can not be caused, the injury to the uterine fundus can be well avoided, and serious medical accidents such as uterine perforation and the like can not occur. Therefore, the technical scheme of the rear camera ensures that the clinical operation process of the induced abortion is safer and more effective.
