[0041] The adjusting mechanism 5 includes a first motor 501, a rotating rod 502, a driving wheel 503, a driven wheel 504, an extension rod 505, a pulley 506, a lead screw 507, a hook neck 508, a sliding sleeve 509, a second motor 510, a slide groove 511, a slider 512 and a ball 513. The first motor 501 is fixedly installed inside the ring remover 1, the rotating rod 502 is fixedly installed on the output shaft of the first motor 501, the driving wheel 503 is fixedly installed outside the rotating rod 502, and the top of the driving wheel 503 A driven wheel 504 is meshed, an extension rod 505 is installed inside the ring remover 1, a pulley 506 is installed outside the extension rod 505, a lead screw 507 is installed inside the ring remover 1, a hook neck 508 is movably installed inside the inner tube 2, a sliding sleeve 509 is sleeved on the outside of the lead screw 507, a second motor 509 is installed inside the hook neck 508, a slide groove 511 is provided on the outside of the ring remover 1, a slider 512 is installed on the front side of the hook neck 508, and a ball bearing 513 is installed on the bottom of the ring remover 1.
[0042] Specifically, by providing the adjustment mechanism 5, the various structures of the adjustment mechanism 5 cooperate with each other, thereby making it easier to adjust the distance and angle of the ring removal hook body 3, thereby facilitating the removal of the ring removal hook body 3 at different depths.
[0043] exist Figure 1 and Figure 2 In the embodiment, a receiving groove is provided inside the ring remover 1 , the inner tube 2 is located inside the receiving groove, and a battery 6 is installed inside the display screen 4 .
[0044] Specifically, the front end of the ring remover 1 is small and the back end is large, because the front part enters the cervix and uterine cavity, and the smaller front end can avoid causing discomfort to the patient; it starts to gradually increase 12 cm from the top of the hook, and the transition is smooth. The 12 cm is to ensure smooth removal of the ring from a large uterus, and the smooth transition is for the comfort of the ring remover. The large back end is convenient for holding, and at the same time the transition connects to a relatively large display screen 4.
[0045] exist Figure 1 and Figure 2 In the figure, a miniature camera 7 is fixedly installed on the top of the ring remover 1, the diameter of the miniature camera 7 is one millimeter, and an illumination light source 8 is installed on the top of the ring remover 1.

The inner tube 2 of the ring remover 1 that wraps the cable is made of medical-grade high-strength insulating plastic to ensure durability and biocompatibility. The inner tube can separate the ring removal hook body 3 from the cable. The cable passes through the inner tube 2, and the ring removal hook body 3 passes between the inner tube 2 and the outer tube, so that they are not worn or damaged, thereby improving their service life. At the same time, the inner tube 2 is made of insulating plastic to reduce the influence of the magnetic field on the conduction of electrical signals, thereby ensuring the stability of signal transmission.
[0052] exist Figure 2 and Figure 4 In the figure, the display screen 4 is a high-resolution liquid crystal display screen, the extension rod 505 is rotatably connected to the inner bottom wall of the ring remover body 1, the driven wheel 504 and the extension rod 505 are connected to each other, and the number of the pulleys 506 is two.
[0053] Specifically, under the illumination of the lighting source 8 at the front end of the ring remover 1, the miniature camera 7 at the front end of the ring remover 1 is connected to the display screen 4 through a cable. The display screen 4 adopts a high-resolution liquid crystal display screen with good contrast and clarity, and the display screen can be flipped, which is suitable for use in a medical environment. It can display the relative position of the ring removal hook and the intrauterine contraceptive device in real time, helping the doctor to accurately find the position of the intrauterine contraceptive device, and at the same time evaluate whether the intrauterine contraceptive device has abnormal conditions such as incarceration or breakage before the ring is removed.
[0054] In Figure 2 and Figure 4 two pulley wheels 506 are respectively located outside the lead screw 507 and the extension rod 505. The two pulley wheels 506 are connected by a transmission belt. The bottom of the ball 513 is rotatably connected to the top of the display screen 4. The output shaft of the second motor 510 is interconnected with the bottom of the ring-removing hook body 3. A charging port is provided at the bottom of the display screen 4.
[0055] In Figure 6 the positioning system of the ring-removing hook includes a main control module, a positioning display module, an image acquisition module, an illumination module, a power supply module and a ring-removing hook adjustment module;
[0056] Among them, the main control module controls the positioning display module, the image acquisition module, the illumination module, the power supply module and the ring-removing hook adjustment module, so as to ensure the coordinated work of each module and thus quickly complete the ring removal;
[0057] Positioning display module, the images collected by the image acquisition module are imported into the positioning display module, so that medical staff can quickly determine the ring removal position;
[0058] Illumination module, through the light source, it is more convenient for medical staff to observe the conditions in the cervix and uterine cavity;
