DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are indicated by the same reference numerals.

[0020] As shown in the figure, an intrauterine ring remover for obstetrics and gynecology includes a first clamp body 1 and a second clamp body 3. The first clamp body 1 and the second clamp body 3 are arranged up and down. At the same time, a guide structure is provided between the first clamp body 1 and the second clamp body 3. The guide structure is used to guide the first clamp body 1 to move along the length direction of the second clamp body 3, so that the first clamp body 1 and the second clamp body 3 can slide relative to each other.

[0021] Specifically, the guide structure is a guide block 7 and a guide groove 8 and are respectively arranged on the sides of the first caliper body 1 and the second caliper body 3 that are close to each other. In the present embodiment, the guide block 7 is arranged on the first caliper body 1 and the guide groove 8 is arranged on the second caliper body 3. The guide block 7 is preferably convex. In another method, the shape of the guide block 7 in other prior arts is also used to achieve the effect of limited sliding.

[0022] In another embodiment, the guide block 7 may be disposed on the second caliper body 3 and the guide groove 8 may be disposed on the first caliper body 1 to achieve the same limited sliding effect.

[0023] Furthermore, the ring remover also includes a holding handle 6, which is arranged at the end of the first clamp body 1 and the second clamp body 3, so that the first clamp body 1 and the second clamp body 3 form a front end at one end away from the holding handle 6, and the front end is used to extend into the uterine cavity to complete the clamping and pulling action. The holding handle 6 is used to drive the first clamp body 1 and the second clamp body 3 to move relative to each other to adjust the first traction head 2 and the second traction head 4 to approach / separate from each other.

[0024] Specifically, the holding handle 6 includes a fixed handle 9 and an operating handle 10, wherein the fixed handle 9 is fixedly connected to the end of the second pliers body 3, and an operating groove 11 is opened on the fixed handle 9, so that the middle section of the operating handle 10 is hinged in the operating groove 11, and at the same time, a movable groove 12 is provided at the upper end of the operating handle 10 along its own length direction, and a connecting block 13 is movably arranged in the movable groove 12. The specific movable connection method is a sliding limit, which is achieved by setting sliders on both sides of the connecting block 13 and setting a sliding groove on the inner wall of the movable groove 12. At the same time, the first pliers body 1 and the slider are hinged, so that when the operator holds the operating handle 10 to drive the operating handle 10 to rotate, the slider can slide in the sliding groove, thereby maintaining the hinge with the first pliers body 1, thereby driving the first pliers body 1 to move along the length direction of the second pliers body 3.

[0025] At the same time, in order to limit the range of movement of the first pliers body 1, in the present embodiment, a constraint surface 14 is formed in the operating groove 11, and the constraint surface 14 is used to contact the operating handle 10 to limit the range of movement of the operating handle 10. The constraint surface 14 is specifically the inner side surface of the operating groove 11. In another embodiment, an additional constraint block can also be provided in the operating groove 11. In this case, the constraint surface 14 is the outer surface of the constraint block.

[0026] At the same time, in order to achieve the restraining effect, the length of the guide groove 8 can also be limited so that when the guide block 7 moves to the front end of the guide groove 8, it is the maximum movement range, and at this time the first pulling head 2 and the second pulling head 4 are in contact with each other.

[0027] Furthermore, the front ends of the first pliers body 1 and the second pliers body 3 respectively form an arc-shaped first pulling head 2 and a second pulling head 4, wherein the arcs of the first pulling head 2 and the second pulling head 4 are in opposite directions, specifically, the arc direction of the first pulling head 2 is toward the gripping handle 6, and the arc direction of the second pulling head 4 is away from the gripping handle 6, so that the first pulling head 2 and the second pulling head 4 can be assembled with each other to form a circular pulling cavity 5, so that the contraceptive ring can be mounted through the circular pulling cavity 5 to achieve the purpose of pulling protection.

[0028] In another embodiment, the circular pulling cavity 5 may also be an ellipse, an oblique circle or an arc circle, so as to achieve the packaging shape required by the present application.

[0029] Specifically, in order to further improve the safety during traction and reduce damage to the inner wall of the uterine cavity, the first traction head 2 and the second traction head 4 both include a traction segment 15 and a soft rubber head 16, wherein the soft rubber head 16 can be specifically made of silicone or plastic material to achieve the purpose of soft contact, and the traction segment 15 is made of hard material to ensure the stability of traction, and, in order to achieve the connection between the soft rubber head 16 and the traction segment 15, in one way, the soft rubber head 16 can be adhered to the end of the traction segment 15. In this embodiment, a first plug hole 17 is formed at the end of the traction segment 15, and a first plug rod 18 is formed on the soft rubber head 16 and plugged into the first plug rod 18, thereby completing the connection and fixation with the traction segment 15, and the plugging method can avoid the adverse effects of chemical substances caused by adhesion on the human body.

[0030] Furthermore, in order to achieve different usage effects, the first clamp body 1 is provided with a second socket 20 corresponding to the first traction head 2, and the first traction head 2 is provided with a second insertion rod 21 and plugged into the second socket 20, so that when faced with a contraceptive ring that has been used for a short time, the first traction head 2 can be directly removed, and only the second traction head 4 can be used to achieve the traction effect. For a long time of use, which leads to adhesion between the contraceptive ring and the cervix, the first traction head 2 can be reinstalled, and the traction effect can be achieved through the traction cavity 5.

[0031] Furthermore, in order to improve the connection stability during pulling, anti-slip grooves 19 are arranged on the sides of the two pulling sections 15 that are close to each other.

[0032] In one embodiment, the anti-slip pattern 19 is irregular in shape or arranged in other regular patterns.

[0033] Specifically, the anti-slip pattern 19 is in a strip shape. In a specific configuration, the anti-slip pattern 19 is evenly arranged along the length direction of the pulling section 15 , so that the anti-slip pattern 19 is parallel to the axis of the pulling cavity 5 .

[0034] In the second embodiment, the anti-slip pattern 19 is arc-shaped and arranged along the axial direction of the pulling section 15, so that when pulling, the anti-slip pattern 19 can be embedded in the gap of the interlocking ring in a small range, thereby greatly improving the connection stability of the interlocking ring.

[0035] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
