Problems solved by technology

[0004] In the existing direct-viewing artificial flow device, the operating end is usually set to a certain radian, but this radian is fixed, and the shape of the uterus and the position of the vagina are different for each person, so it is very easy to use during clinical use. Due to the difference in the shape and position of the uterus, the direct-viewing artificial abortion device cannot enter the uterus smoothly and reach all corners of the uterus. It is necessary for doctors and nurses to change the angle and position of the uterus to realize the artificial abortion operation. For some special-shaped uterus or special position Uterus, sometimes the medical staff cannot achieve abortion even if the angle and position of the uterus are changed

Embodiment 1

[0088] Embodiment 1: Plastic tube shape with a spatula The moldable direct-view flow curettage device of the present invention

[0089] refer to Figure 1 to Figure 1-5 , The moldable direct-viewing curettage device of the present embodiment includes a curettage mechanism 1, an observation mechanism 2, a circuit 3, a negative pressure suction mechanism 4, an operating rod 5 and a shaping mechanism 9.

[0090] The curettage mechanism 1 includes at least one curette 11 , and the curettage 11 is arranged at the front end of the operating rod 5 and within the field of view of the observation mechanism 2 .

[0091] The observation mechanism 2 includes an illumination module 21, a lens module 22 and a signal processing module 23; in the light field of the illumination module 21, images and videos observed by the lens module 22 pass through the signal processing module 23 After processing, it is output by the circuit 3.

Embodiment 2

[0111] Embodiment 2: Shaped tube type with scraper cup The shapeable direct-view flow curettage device of the present invention

[0112] refer to Figure 2 to Figure 2-3 , The difference between this embodiment and the embodiment is that in this embodiment, the curette 11 is a scraper cup 11-2.

[0113] The front end of the scraper cup 11-2 is blunt, and contains at least one scraping strip 11-21 around it. The blunt head design can ensure that the scraper cup 11-2 will not cause accidental injury to the tissue at the front end of the scraper cup 11-2 during the forward movement process. In clinical use, the scraper strip 11-2 21 It is convenient to scrape the implanted embryonic tissue from the uterus.

[0114] refer to Figure 2-2 and Figure 2-3 , in the present embodiment, the front end of the scraper cup 11-2 is a scraper table 11-23 provided with a through hole 11-22. The scraper cup 11-2, the scraper table 11-23 also rotates accordingly, can scrape the embryonic ti...

Embodiment 3

[0117] Embodiment 3: Shaped Rod Type with Scraping Mesh According to the present invention, it can be molded directly into the flow curettage device

[0118] refer to Figure 3 to Figure 3-6 , The difference between this embodiment and Embodiment 1 is that in this embodiment, in this embodiment, the curettage device 11 is a scraping net 11-3.

[0119] In this embodiment, the curette 11 of the curettage mechanism 1 is a scraper 11-3. The camera 22-1 can directly observe the situation behind the scraping screen 11-3 from the mesh gap, even if the scraping screen 11-3 is not made of transparent materials, it can realize the whole process of operation observation and the monitoring of the operation area. Panoramic observation.

[0120] refer to image 3 , in this embodiment, the curettage 11-3 of the curettage device 11 of the curettage mechanism 1 can be compressed in the outer sheath 5-0, when the constraint of the outer sheath 5-0 is removed backward , the scraping screen 1...

Abstract

The invention discloses a shaping direct-viewing curettage device for induced abortion. The curettage device includes a curettage mechanism, an observation mechanism, a circuit, a negative pressure suction mechanism, an operating rod and a shaping mechanism. The shaping mechanism can adjust the angles and directions of the front end of the operating rod so as to adapt different uterine shapes andpositions. Through the technical scheme of a rear arranged camera, a diagnostic curettage device can be completely in the field of view of the camera, so that full visibility can be realized during operation, and observation dead zones can not exist. Meanwhile, the operation dead zones of the diagnostic curettage device can not exist due to the shielding generated by the height of a lens module; embryonic tissue implanting at any positions in the uterus can be completely removed, especially near the outlet of the fallopian tube which is the implantation position at the bottom of the uterus; and the diagnostic curettage device can also remove the embryonic tissue easily, so that the diagnostic curettage device is safer and more efficient during clinical using. A direct-viewing curettage system for induced abortion is also disclosed. The curettage system including the curettage device can perform operation under the real-time displaying of a display system, so that accurate, safe and efficient abortion operation can be realized.

Description

technical field [0001] The invention relates to an endoscopic surgical instrument, in particular to a shapeable direct-viewing flow curettage device and system used 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 ...
