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.

Curettage device 11 sets up in observation mechanism 2's the field of vision, during clinical operation, can be in under observation mechanism 2's the effect of lens module 22, carry out the whole operation of stream of people operation under the condition of looking directly, can observe very clearly whether the operation in-process embryo tissue clears away totally clean, can observe whether cause unexpected injury to the uterus in addition to the operation, and clinical use process is very safe, reliable. In addition, the uterine curettage mechanism 1 and the negative pressure suction mechanism 4 can be designed to be relatively independent mechanisms, so that the curettage effect of the uterine curettage mechanism 1 on the bed embryo is ensured, and meanwhile, the curetted tissue and the generated tissue fluid such as blood and the like can be very effectively and quickly sucked and discharged out of the body through the negative pressure suction mechanism 4.

In particular, the lens module 22 at least comprises 2 cameras 22-1, so that the problem of limited observation field of view of the existing single lens is well solved, and the observation field of view in the operation process can be effectively enlarged. Particularly, when the cameras 22-1 are respectively disposed in front of and at the side of the operating rod 5, a stereoscopic observation space can be formed around the operating rod 5 by superimposing the observation fields, and the clinical observation effect is very good.

Further, at least 1 camera 22-1 is disposed at the front end 5-1 of the operation rod 5. The camera 22-1 disposed in front of the operation lever 5 can well observe the area in front of the operation lever 5.

At least 1 camera 22-1 is arranged on the side 5-5 of the operating rod 5. The camera 22-1 provided on the side surface 5-5 of the operation lever 5 can observe the side surface of the operation lever 5.
