The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0024] Example 1

[0025] See also Figures 1 to 6 The utility model preferably provides a technical solution: an intrauterine ring removal device for obstetrics and gynecology, comprising: a mounting frame 1, a support cover assembly arranged on the mounting frame 1, the support cover assembly is composed of an expansion plate assembly 2 and a transmission frame 3 distributed front and back, when the transmission frame 3 is running, the expansion plate assembly 2 expands outward and forms an expansion channel for intrauterine ring removal; a limit bracket 5 slidably installed in the middle of the transmission frame 3, which is composed of a rod and a head arranged at the front end of the rod, the head includes a limit sleeve 502, and a support ball 603, and the limit groove 602 provided on the outer wall of the support ball 603 is limitedly installed with a plurality of limit columns 601 provided on the inner wall of the limit sleeve 502; and a through groove 604 provided in the middle of the support ball 603, the through groove 604 is a funnel structure with wide ends and narrow in the middle; and also includes a ring removal hook assembly 4, and the ring removal hook assembly 4 passes through the interior of the through groove 604 and is limitedly provided with a first limit ball 605 and a second limit ball 606 at both ends of the through groove 604.

[0026] The present application provides an intrauterine ring removal device with expansion and multi-angle fine adjustment. The expansion function can provide an operating space for the ring removal, and the multi-angle adjustment can facilitate the ring removal device to accurately hook the IUD. Figure 1-5 As shown, the expansion cover assembly is composed of a group of transmission frames 3 and an expansion plate assembly 2 arranged at the front end of the transmission frame 3. The transmission frame 3 here serves to provide power for the expansion and retraction process of the expansion plate assembly 2, thereby providing power for the formation of the ring-taking expansion channel;

[0027] The transmission frame 3, the limiting bracket 5 arranged in the middle thereof is composed of a rod portion and a head portion, and the limiting sleeve 502 where the head portion is located and the supporting ball 603 are respectively installed by limiting the limiting column 601 and the limiting groove 602 arranged thereon. Figure 6 As shown, the ring hook assembly 4 is further matched. The ring hook assembly 4 here has the structural characteristics that: it runs through the interior of the through slot 604 and is limited by a first limiting ball 605 and a second limiting ball 606 at both ends of the through slot 604, and the through slot 604 is a funnel structure with wide ends and narrow in the middle. Figure 6 As shown, it is worth noting that the material of the first limiting ball 605 and the second limiting ball 606 is preferably an elastic rubber material. Therefore, when operating the ring-taking hook assembly 4, the first limiting ball 605 and the second limiting ball 606 on the ring-taking hook assembly 4 can be deformed at both ends of the through groove 604 to realize the multi-directional micro-deflection process of the ring-taking hook assembly 4, and cooperate with the limiting groove 602 and the limiting column 601 to further realize the circumferential flipping of the ring-taking hook assembly 4, thereby realizing the multi-angle flexible ring-taking process of the ring-taking hook assembly 4 to meet the needs of different shapes and position nodes. In order to meet the requirements for removing the IUD, the utility model adopts the funnel structure characteristics of the through groove 604, which is wide at both ends and narrow in the middle, combined with the first limiting ball 605 and the second limiting ball 606 set at both ends, as well as the limiting installation of the limiting sleeve 502 and the supporting ball 603, so that the limiting bracket 5 not only supports the ring removal process of the ring removal hook assembly 4, but also enables the ring removal hook assembly 4 to have multi-directional fine-tuning and circumferential flipping performance, so that the IUD can be removed accurately, flexibly and stably under the expansion channel provided by the expansion cover assembly.

[0028] Example 2

[0029] As another embodiment of the present utility model, the transmission frame body 3 includes two slide grooves 301 opened on both sides of the mounting frame 1, and a slider 302 limitedly installed inside each slide groove 301, and a transmission plate 303 fixed on the opposite surfaces of the two sliders 302 is used for the installation of the limiting bracket 5; it also includes two transmission rods 304 arranged on the transmission plate 303, and the two transmission rods 304 extend toward the head of the limiting bracket 5 at one end away from the transmission plate 303 and are fixed with a transmission member 305, and the transmission member 305 is a sleeve structure that is wide in front and narrow in the back and acts on the expansion plate assembly 2.

[0030] In this embodiment, if Figure 3 , 5 As shown, the transmission plate 303 slides in the inner part of the slide groove 301 through the slider 302, which is not only used for the installation of the limit bracket 5, but also fixed with a transmission member 305 through a transmission rod 304, and the transmission member 305 is wide at the front and narrow at the back. Figure 5 When the transmission member 305 moves forward and backward and acts on the expansion plate assembly 2, the expansion plate assembly 2 can be expanded or retracted through its morphological characteristics, thereby achieving the expansion or resetting of the ring-taking expansion channel.

[0031] Furthermore, the expansion plate assembly 2 includes a mounting groove 201 formed in an annular manner at the front end of the mounting frame 1, and a mounting ring and an L-shaped frame 202 fixed inside each mounting groove 201, a telescopic rod 203 arranged in the mounting ring, one end of which passes inwardly through a through hole formed on the L-shaped frame 202 and is provided with a transmission roller 206, and the transmission roller 206 is in contact with the outer wall of the transmission member 305, and the expansion plate body 205 fixed at the other end is used to form the side wall of the expansion channel; it also includes a first spring 204 arranged on the outer wall of the telescopic rod 203 between the L-shaped frame 202 and the mounting ring, and the first spring 204 is used to reset the telescopic rod 203.

[0032] Here, each telescopic rod 203 is provided with a transmission roller 206 that fits with the outer wall of the transmission member 305 at one end thereof, and the expansion plate 205 that is provided outward at the other end thereof can form the side wall of the expansion channel. With the action of the first spring 204, when the transmission member 305 moves back and forth through the power of the slider 302 sliding back and forth inside the slide groove 301, with the morphological characteristics of the transmission member 305 that is wide at the front and narrow at the back, the expansion plate 205 in the retracted state passes through the vagina and the cervical os in turn, and then the transmission member 305 is driven to move backward, so that the multiple telescopic rods 203 and the expansion plate 205 on the telescopic rods 203 can be expanded outward, thereby completing the establishment of the ring removal channel. It is worth noting that the operation here is gentle so as not to cause discomfort to the patient.

[0033] Furthermore, the front end of each expansion support plate 205 is provided with a chamfered surface, and the chamfered surface can be a curved surface, such as Figure 5 As shown, the purpose of this design is to reduce the discomfort caused when the device is inserted into the vagina and cervix.

[0034] Furthermore, a ring light 701 is installed on the front side of the transmission member 305. Figure 1 , 2 As shown, the design improves the operating environment of the ring-removing hook assembly 4 to facilitate the operation and observation of the operator.

[0035] Furthermore, a mounting frame 207 and a mounting rod 306 fixed to the side wall of one of the sliders 302 are fixed to the rear end of the mounting frame 1, and the end of the mounting rod 306 away from the slider 302 passes backward through the notch opened in the side wall of the mounting frame 207 and is provided with a handle; it also includes a threaded groove and a threaded hole respectively opened on the mounting rod 306 and the notch, and a bolt 307 is provided in the threaded groove.

[0036] Here, one end of the mounting rod 306 is fixed to one of the sliders 302, and the other end is provided with a handle, which cooperates with the bolt 307 provided in the threaded groove on it. Figure 3 , 5As shown, when the expansion plate assembly 2 needs to be driven to expand or retract, the handle can be pulled to achieve the forward and backward movement of the slider 302, and the position of the mounting rod 306 can be locked by the bolt 307.

[0037] Furthermore, a handle 208 is fixed to a side of the mounting frame 207 away from the notch.

[0038] Furthermore, the rod portion includes two connecting rods 501 slidably mounted in the middle of the transmission plate 303, and one end of the two connecting rods 501 is fixedly connected to the limiting sleeve 502 where the head is located, and the other end is provided with a connecting frame 503; and a second spring 504 is arranged on the outer wall of the connecting rod 501 between the connecting frame 503 and the transmission plate 303, and the second spring 504 is used for resetting the corresponding connecting rod 501.

[0039] Here, the two connecting rods 501 where the rod is located are slidably installed with the transmission plate 303. Therefore, when the ring-removing hook assembly 4 needs to move forward or backward, the limiting installation of the limiting sleeve 502 and the supporting ball 603 realizes the synchronous movement process of the limiting bracket 5 and the ring-removing hook assembly 4. At this time, the limiting bracket 5 does not limit the angle adjustment of the ring-removing hook assembly 4 when the ring-removing hook assembly 4 removes the ring, and provides a support for the ring-removing hook assembly 4 during the ring-removing process, thereby further improving the ring-removing stability and convenience of the ring-removing hook assembly 4.

[0040] Furthermore, the ring-taking hook assembly 4 includes an operating rod 401, which runs through the middle of the entire device and is provided with a first limiting ball 605 and a second limiting ball 606 at both ends of the through slot 604. Figure 6 Also includes a hook portion 403 and a hand-held portion 402 respectively disposed at the front and rear ends of the operating rod 401, where the hand-held portion 402 is operated, such as Figure 2 , 5 As shown, the angle adjustment process of the hook portion 403 moving forward, backward, sideways, and rotating is realized.

[0041] Furthermore, the hook portion 403 is a barb structure, and a barb is provided on the inner side of the barb structure, such as Figure 5 As shown, this design improves the stability of the hook portion 403 in hooking the contraceptive ring.

[0042] The specific operation process of removing the ring is as follows:

[0043] First, insert the device into the patient's vagina and cervix and fix it. The fixing operation here can be performed by holding the handle 208 to ensure the position of the mounting frame 1, and then the transmission frame 3 is driven to move backward and locked through the transmission member 305, so as to realize the outward expansion of the expansion plate assembly 2 and complete the establishment of the expansion channel before the ring is removed; and after the expansion channel is established, the hand-held part 402 where the ring removal hook assembly 4 is located is held, so that the operating rod 401 is multi-directionally deflected, circumferentially flipped or driven to move synchronously forward and backward inside the head where the limiting bracket 5 is located, so as to realize the ring removal operation of the ring removal hook assembly 4.

[0044] In the present utility model, unless otherwise clearly stipulated and limited, terms such as "install", "connected", "connect", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection. There are many ways of detachable installation, for example, by means of plug-in and snap-in cooperation, etc.

[0045] The specific description of the present invention in the above embodiments is only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above-mentioned utility model, which fall within the scope of protection of the present invention.
