[0019] refer to Figures 1 to 7 A gynecological intrauterine ring remover comprises a uterine expansion shell 1, a fixing rod 2, a removal mechanism 3 and a clamping mechanism 4; an elastic membrane is arranged on the outer wall of the uterine expansion shell 1, four fixing rods 2 are arranged around the circumference and are respectively fixed on the inner wall of the uterine expansion shell 1, the removal mechanism 3 is arranged on the side where the four fixing rods 2 are close to each other, and the clamping mechanism 4 is arranged inside the removal mechanism 3.

[0020] It should be explained that the insertion end of the uterine expansion shell 1 is configured to be arc-shaped to avoid scratching the inner wall of the uterine cavity when the uterine expansion shell 1 is inserted or removed, and a ring removal hole is opened in the middle to facilitate observation of the position of the contraceptive ring and to facilitate clamping and fixing the contraceptive ring.

[0021] That is to say, the uterine expansion shell 1 can be extended into the patient's uterine cavity, and the contraceptive ring is first clamped and fixed by the clamping mechanism 4, and then the contraceptive ring in the incarcerated state is pulled out by the removal mechanism 3, that is, the contraceptive ring inserted into the inner wall of the uterine cavity is pulled out, and finally the uterine expansion shell 1 is taken out, and the ring removal work is completed.

[0022] As a preferred embodiment, the taking-out mechanism 3 includes a rectangular tube 31, an inner tube 1 32, an inner tube 2 33, and a micro camera 34; the rectangular tube 31 is fixed to one end of the four fixed rods 2 close to each other, the inner tube 1 32 is arranged above the rectangular tube 31, the inner tube 2 33 is coaxially arranged below the inner tube 1 32, and the micro camera 34 is annularly installed at the lower end of the fixed rod 2; It should be explained that the micro camera 34 can both emit light and convert the captured images into electrical signals.

[0023] In addition, it also includes an adjustment component 1, an adjustment component 2 and an adjustment component 3, and the adjustment component 1, the adjustment component 2 and the adjustment component 3 are arranged around the circumference of the rectangular tube 31 in sequence at an angle of 90°.

[0024] As a preferred embodiment, the regulating component 1 includes an electrical converter 151, a flow channel 152, a rectangular ring 153, a fixed cylinder 154, a sliding rod 155, a solenoid valve 156, and a connecting hose 157; the electrical converter 151 is installed on a fixed rod 2, the electrical converter 151 is electrically connected to the micro camera 34, the flow channel 152 is opened in the rectangular cylinder 31, and one end thereof is connected to the output end of the electrical converter 151, a slide groove 1311 is opened on one group of symmetrical inner walls of the rectangular cylinder 31, and a slide groove 2312 is opened on another group of symmetrical inner walls, and The slide groove 2 312 is located above the slide groove 1 311, the rectangular ring 1 53 is slidably set in the slide groove 1 311, the fixed cylinder 1 54 is fixed on the inner wall of the rectangular cylinder 31, the sliding rod 1 55 is sealingly slid in the fixed cylinder 1 54, and the sliding rod 1 55 is fixed to one side wall of the rectangular ring 1 53, a through hole 1 is opened on the outer wall of the fixed cylinder 1 54, the solenoid valve 1 56 is set in the through hole 1, and the solenoid valve 1 56 is electrically connected to the external control end, one end of the connecting hose 1 57 is connected to the fixed cylinder 1 54, and the other end is connected to the flow channel 1 52.

[0025] It should be noted that the micro camera 34 can capture the relative position of the IUD and the uterine wall, and convert the coordinate position of the specific image between the IUD and the uterine wall into an electrical signal, and then convert the electrical signal into an air pressure signal through an electrical converter. Therefore, adjustment components one, two and three adjust the moving direction of the clamping mechanism 4 with different air pressures, and finally move the IUD out from the opposite direction of insertion into the uterine wall.

[0026] Specifically, in the adjustment component 1, the micro camera 34 imports the X-axis specific coordinate information of the horizontal angle between the contraceptive ring and the inner wall of the uterus into the electrical converter 151. The electrical converter 151 can convert the X-axis coordinate information into air pressure 1, and this air pressure 1 will enter the fixed tube 154 through the flow channel 152, thereby pushing or pulling the sliding rod 155 to move, and then driving the rectangular ring 153 to move synchronously.

[0027] As a preferred embodiment, the regulating component 2 includes an electrical converter 2 61, a flow channel 2 62, a rectangular ring 2 63, a fixed cylinder 2 64, a sliding rod 2 65, a solenoid valve 2 66, and a connecting hose 2 67; the electrical converter 2 61 is installed on a fixed rod 2, the electrical converter 2 61 is electrically connected to the micro camera 34, the flow channel 2 62 is opened in the rectangular cylinder 31, and one end thereof is connected to the output end of the electrical converter 2 61, the rectangular ring 2 63 is slidably arranged in the slide groove 2 312, the fixed cylinder 2 64 is fixed on the inner wall of the rectangular cylinder 31, and the sliding The movable rod 2 65 is sealed and slides in the fixed cylinder 2 64, and the sliding rod 2 65 is fixed to one side wall of the rectangular ring 2 63. A through hole 2 is opened on the outer wall of the fixed cylinder 2 64. The solenoid valve 2 66 is arranged in the through hole 2, and the solenoid valve 2 66 is electrically connected to the external control end. One end of the connecting hose 2 67 is connected to the fixed cylinder 2 64, and the other end is connected to the flow channel 2 62. The inner cylinder 1 32 is slidably arranged in the intersection space of the rectangular ring 1 53 and the rectangular ring 2 63, and a lap ring is arranged on the outer wall of the inner cylinder 1 32, which is placed above the rectangular ring 2 63.

[0028] Specifically, in the same way, in the adjustment component 2, the micro camera 34 imports the Y-axis specific coordinate information of the horizontal angle between the contraceptive ring and the inner wall of the uterus into the electrical converter 2 61. The electrical converter 2 61 can convert the Y-axis coordinate information into air pressure 2. This air pressure 2 will be introduced into the fixed tube 2 64 through the flow channel 2 62, thereby pushing or pulling the sliding rod 2 65 to move, and then driving the rectangular ring 2 63 to move synchronously.

[0029] Therefore, the horizontal movement direction of the inner cylinder 1 32 can be determined by the movement of the rectangular ring 1 53 and the rectangular ring 2 63 .

[0030] As a preferred embodiment, the regulating component three includes an electrical converter three 71, a flow channel three 72, a fixed cylinder three 73, a sliding rod three 74, a solenoid valve three 75 and a connecting hose three 76; the electrical converter three 71 is installed on the fixed rod 2, the electrical converter three 71 is electrically connected to the micro camera 34, the flow channel three 72 is opened in the rectangular cylinder 31, and one end thereof is connected to the output end of the electrical converter three 71, the fixed cylinder three 73 is arranged with multiple circumferences, all fixed on the lower end surface of the inner cylinder one 32, the sliding rod three 74 is arranged with multiple circumferences, one end of which is sealed and slidably arranged in the fixed cylinder three 73, and the other end is jointly fixed on the upper end surface of the inner cylinder two 33, the fixed cylinder three 73 is provided with a through hole three on the outer wall, the solenoid valve three 75 is arranged in one of the through holes three, and the solenoid valve three 75 is electrically connected to the external control end, one end of the connecting hose three 76 is connected to a fixed cylinder three 73 provided with the solenoid valve three 75, and the other end is connected to the flow channel three 72.

[0031] Among them, the three solenoid valves can be controlled externally so that the spaces inside the fixed cylinder 1 54, the fixed cylinder 2 64 and the fixed cylinder 3 73 are connected or isolated from the outside. That is to say, when the solenoid valves are closed, the three air pressures generated can push or pull the respective sliding rods to move. When the solenoid valves are opened, no air pressure is generated in the three inner spaces, so that the respective sliding rods cannot be pushed or pulled to move. Specifically, in the same way, in the adjustment component three, the micro camera 34 imports the specific Z-axis coordinate information of the horizontal angle between the contraceptive ring and the inner wall of the uterus into the electrical converter three 71. The electrical converter three 71 can convert the Z-axis coordinate information into air pressure three. This air pressure three will be introduced into the fixed tube three 73 through the flow channel three 72, thereby pushing or pulling the sliding rod three 74 to move, and then driving the inner tube two 33 to move synchronously.

[0032] In detail, since the moving trajectory of the inner cylinder 2 33 depends on the moving speed of the sliding rod 1 55, the sliding rod 2 65 and the sliding rod 3 74, and the moving speed of the sliding rod 1 55, the sliding rod 2 65 and the sliding rod 3 74 depends on the numerical ratio of the air pressure 1, the air pressure 2 and the air pressure 3, therefore, if the displacement between the X-axis and the base point is L, the displacement between the Y-axis and the base point is H, and the displacement between the Z-axis and the base point is K, then L / H / K is the ratio of the numerical values ​​of the air pressure 1, the air pressure 2 and the air pressure 3, that is, the ratio of the displacement of the three is proportional to the ratio of the air pressures of the three, and thus the moving trajectory of the inner cylinder 2 33 can be in the same straight line as the specific insertion direction of the contraceptive ring relative to the inner wall of the uterus.

[0033] Among them, the values ​​of L and H are real numbers, that is, when the displacement is a negative number, the converted air pressure is negative pressure, that is, a pushing effect. On the contrary, when the displacement is a positive number, the converted air pressure is positive pressure, that is, a pulling effect.

[0034] As a preferred embodiment, the clamping mechanism 4 includes a T-shaped rod 41, a connecting plate 42, a rotating shaft 43, a pushing rod 44, a U-shaped rod 45, a clamping arm 46 and a collar 47; an annular groove is provided in the lower end of the inner cylinder 33, the T-shaped rod 41 is rotatably set in the annular groove, a rectangular through hole is provided in the middle of the T-shaped rod 41, the connecting plate 42 is fixed to the rear end side of the lower section of the T-shaped rod 41, the rotating shaft 43 is fixed to the lower end of the connecting plate 42, the pushing rod 44 is a rectangular rod, which slides through the rectangular through hole, the U-shaped rod 45 is inverted and fixed to the lower end of the pushing rod 44, two clamping arms 46 are symmetrically arranged, one end of which is rotatably set on the rotating shaft 43, and two collars 47 are symmetrically arranged, which are respectively hinged at both ends of the U-shaped rod 45, and are slidably set on the two clamping arms 46.

[0035] It needs to be explained that when the IUD needs to be clamped, since the spatial position of the IUD is uncertain, it is necessary to twist the push rod 44 first so that the clamping ends of the two clamp arms 46 can reach the best clamping position for the IUD without touching the rest of the IUD, and then push the push rod 44 to drive the U-shaped rod 45 downward. The downward movement of the two rings 47 can drive the two clamp arms 46 to close, so that the two clamp arms 46 can complete the clamping of the IUD.

[0036] That is to say, after the IUD is clamped, the moving trajectory of the inner tube 2 33 is the moving trajectory of the IUD.

[0037] In one embodiment, when the horizontal angle and the vertical angle between the IUD and the uterine wall are both α=45°, the values ​​of the air pressure 1, air pressure 2 and air pressure 3 are equal, and the moving speeds of the sliding rod 1 55, the sliding rod 2 65 and the sliding rod 3 74 are the same. Figure 7 The IUD can be removed in the opposite direction of the insertion direction, so the wound surface can reach the minimum area, thereby reducing the patient's pain.

[0038] It should be noted that the three solenoid valves work independently through the external control terminal.

[0039] Specifically, the uterine expansion shell 1 is first inserted into the patient's body and located at the front end of the contraceptive ring, and the three solenoid valves are kept in a closed state. The contraceptive ring is fixed and clamped by the clamping mechanism 4, and then the switches of the three solenoid valves are adjusted in sequence to preliminarily separate the contraceptive ring from the tissue. Specifically, if the ring removal process is a total of 10s to 12s, within the first second, the solenoid valve 1 56 is closed, the solenoid valve 2 66 and the solenoid valve 3 75 are opened, then air pressure 1 is generated in the fixed cylinder 1 54, and there is no air pressure in the fixed cylinder 2 64 and the fixed cylinder 3 73, so that under the action of air pressure 1, the contraceptive ring has only a small displacement in the X-axis direction; within the second second, the solenoid valve 2 66 is closed, the solenoid valve 1 56 and the solenoid valve 3 75 are opened, and air pressure 2 is generated in the fixed cylinder 2 64, and there is no air pressure in the fixed cylinder 1 54 and the fixed cylinder 3 73, so that under the action of air pressure 2, the contraceptive ring has only a small displacement in the Y-axis direction; with the same logic as above, within the third second, the solenoid valve 3 75 is opened. 5 is closed, solenoid valve one 56 and solenoid valve two 66 are opened, air pressure three is generated in fixed cylinder three 73, and no air pressure is generated in fixed cylinder one 54 and fixed cylinder two 64, so that the contraceptive ring has only a small displacement in the Z-axis direction under the action of air pressure three; the above three sections of small displacements all have three small angles with the removal direction of the contraceptive ring, and these three small angles are distributed in a circle in space, and these three small angles can all cause divergent movement between the contraceptive ring and the inner wall of the tissue, so that the contraceptive ring can be separated from the inner wall of the tissue, and within a period of time thereafter, the three solenoid valves are all closed again, so that the contraceptive ring can be pulled out along the insertion direction, that is, through the slight swinging and pulling process of the contraceptive ring in the first three seconds, the tissue adhered to the contraceptive ring will be separated from the contraceptive ring, so that when the contraceptive ring is pulled out along the insertion direction in the latter period of time, the contraceptive ring can reduce the amount of tissue carried, further reduce the degree of trauma, and thus further reduce the patient's pain.

[0040] It should be noted that the friction between the rectangular ring 53 and the slide groove 311 is greater than the self-weight of the rectangular ring 53, that is, when the solenoid valve 56 is opened, the rectangular ring 53 is in a static state, preventing the self-weight of the rectangular ring 53 from driving the inner tube 32 to move.

[0041] Specifically, during implementation, the uterine expansion shell 1 is inserted into the uterus, and the contraceptive ring is first clamped and fixed by the clamping mechanism 4. Then, the tissue adhered to the contraceptive ring is peeled off by adjusting the three solenoid valves, and then the contraceptive ring inserted into the inner wall of the uterus is pulled out in the opposite direction of the insertion direction by adjusting components one, two and three at the same time, thereby avoiding pulling on the traumatic part of the inner wall of the uterus and preventing secondary damage to the traumatic point. Thereafter, the uterine expansion shell 1 is taken out to complete the ring removal work.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
