Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] The inventor has found that in recent years, the number of deaths caused by severe postpartum hemorrhage in my country has been on the rise. After vaginal delivery and cesarean section, postpartum hemorrhage is often caused by uterine atony and placental factors. Cervical clamping, as a common method of rapid hemostasis after delivery, can effectively reduce the amount of bleeding and curb the occurrence of severe postpartum hemorrhage. When implementing cervical clamping, especially for those with postpartum hemorrhage caused by uterine atony and / or placental factors, the toothless oval clamp is usually inserted into the deep vagina to pull the cervix into the deep vagina, and then two oval clamps are used to clamp at the 3 and 9 o'clock positions on both sides of the cervix where the blood vessels are dense, respectively, to clamp the descending branches of the bilateral uterine arteries and part of the open blood sinuses of the lower uterine segment, to stop bleeding, and to stimulate the uterus to contract through the clamping action, further enhancing the hemostatic effect. The cervical clamp operation process generally requires clamping the cervix for an hour, and several cervical clamps are used to operate at the same time. Medical staff will be very tired and too inconvenient.

[0021] Based on the above findings, the present application proposes a maternal cervical contraction clamp, which is designed by designing a grasping clamp assembly at the front end of the clamp body, including multiple grasping clamp units, and three groups of grasping clamp units are designed on the left and right clamp rods respectively, so that the clamping of the cervix is ​​a wrap-around clamp; the grasping clamp assembly is connected to a brake assembly, so that the operator can adjust the opening and closing of the grasping clamp by adjusting the pull ring on the handle, thereby improving the convenience of operation and enhancing the stability of clamping.

[0022] Example 1 See Figure 1-Figure 14 The present application discloses a parturient cervical contraction clamp, comprising a clamp body 1, wherein the clamp body 1 comprises two rotatably connected clamp rods 101, the two clamp rods 101 are connected by a connecting shaft, and one end of the clamp rod 101 is integrally connected with a round handle 102.

[0023] A guide groove is provided inside the end of the pliers rod 101 away from the handle 102, and a control rod 2 is arranged in the guide groove. The two control rods 2 are hinged and limited by the rotating shaft 201 to prevent the control rods 2 from being separated. A connecting rod 3 is fixedly connected to the end of one of the control rods 2 close to the handle 102. The connecting rod 3 is located inside the pliers rod 101 and extends outward from the inner side of the handle 102. The extended end of the connecting rod 3 is rotatably connected to a pull ring 4. A limiting protrusion 5 is also provided on the inner side of the handle 102 to cooperate with the pull ring 4.

The retaining ring 203 is fixedly connected to one end of the spring 1, and the retaining ring 203 is slidably connected on the control rod 2. A fixing ring 101-2 is provided at one end of the movable groove 101-1 close to the handle 102, and the fixing ring 101-2 is used to limit the position of the spring 1 204.

[0025] Three movable grooves 101-1 are provided on the corresponding clamp rod 101 above the tooth groove 202, and the fan wheel 6 is rotatably connected in the movable groove 101-1, and the gear part of the fan wheel 6 is meshed with the tooth groove 202. The three movable grooves 101-1 are distributed on the upper and lower sides and the outer side of the clamp rod 101.

[0026] The side of the sector wheel 6 opposite to the gear is fixedly connected with a gripping assembly 7, which includes a support rod 701 connected to the sector wheel 6, and a Y-shaped piece 702 is connected to the end of the support rod 701. The Y-shaped piece 702 is made of a deformable material.

In the initial state, the extension piece 704 is located on both sides of the support gasket 703. When the support gasket 703 is squeezed, the Y-shaped piece 702 is deformed, pushing the extension pieces 704 on both sides to extend outward, thereby enhancing the wrapping and support stability of the cervix.

[0027] In addition, the Y-shaped member 702 may also be configured to be ball-jointed with the support rod 701 .

[0028] In the initial state, the pull ring 4 is connected to the limiting protrusion 5 close to the clamp rod 101, the spring 1 204 is in an extended state, the sector wheel 6 is in contact with the tooth groove 202 close to the handle 102, the angle between the support rod 701 and the clamp rod 101 is large, the extension piece 704 is in a horizontal state, and the handle 102 components are in a separated state; when the pull ring 4 is pulled to connect the pull ring 4 with the limiting protrusion 5 away from the clamp rod 101, the control rod 2 moves as a whole toward the end close to the handle 102, the spring 1 204 becomes compressed, the sector wheel 6 is in contact with the tooth groove 202 away from the handle 102, the angle between the support rod 701 and the clamp rod 101 becomes smaller, and the handle 102 components are in a gathered state.

[0029] When the supporting gasket 703 is squeezed, the Y-shaped member 702 is deformed, pushing the extension pieces 704 on both sides to extend outward, thereby enhancing the wrapping and supporting stability of the cervix.

[0030] Example 2 Reference Figure 1-Figure 12 The side where the handles 102 are close to each other is fixedly connected with a limit rod 103 and a limit rod 2 104, the limit rod 103 is connected to the left handle 102, the limit rod 2 104 is connected to the right handle 102, and a connecting component is provided on the side where the limit rod 103 and the limit rod 2 104 are close to each other.

[0031] The inner side of the limiting rod 103 is provided with a receiving groove 103-1, and a spring 2 103-2 is arranged in the receiving groove 103-1. The extended end of the spring 2 103-2 is connected to an arc block 103-3. When there is no external force in the initial state, the arc block 103-3 extends out of the receiving groove 103-1. The limiting rod 2 104 is provided with a plurality of limiting grooves 104-1 on the side corresponding to the receiving groove 103-1, and the shape of the limiting grooves 104-1 matches the arc block 103-3. Medical staff can hold the handle 102 and squeeze it to adjust the opening angle of the forceps body 1.

[0032] Example 3 Reference Figure 1-Figure 12 , an illuminating lamp 205 is arranged at one end of the control rod 2 extending out of the clamp rod 101, so as to facilitate the medical staff to observe the wound and clamp accurately. The illuminating lamp 205 adopts the existing structure and is powered by a battery, which is not an improvement point here, so it will not be described in detail.

[0033] The use process of the present invention is: 1. In the initial state, the pull ring 4 is connected to the limit protrusion 5 close to the clamp rod 101, the spring 1 204 is in a stretched state, the fan-shaped wheel 6 contacts the tooth groove 202 close to the handle 102, the angle between the support rod 701 and the clamp rod 101 is large, the extension piece 704 is in a horizontal state, and the handle 102 components are in a separated state; when the pull ring 4 is pulled to connect the pull ring 4 with the limit protrusion 5 away from the clamp rod 101, the control rod 2 moves as a whole toward the end close to the handle 102, the spring 1 204 becomes compressed, the fan-shaped wheel 6 contacts the tooth groove 202 away from the handle 102, the angle between the support rod 701 and the clamp rod 101 becomes smaller, and the handle 102 components are in a gathered state.

[0034] When the supporting gasket 703 is squeezed, the Y-shaped member 702 is deformed, pushing the extension pieces 704 on both sides to extend outward, thereby enhancing the wrapping and supporting stability of the cervix.

[0035] 2. The medical staff can hold the handle of the device and squeeze it to adjust the opening angle of the clamp body 1. When it is necessary to disengage from the limiting groove 104-1, the right handle 102 is bent backwards to make the arc block disengage from the limiting groove 104-1.
