When stopping bleeding after parturient bleeding, First, according to the use requirements, the clamp handle 24 is placed above the connecting rod 6, and the position of the clamp head 23 is adjusted. After the adjustment is appropriate, the fixing block 213 will be pushed by the elastic force of the spring 12 to move the sleeve 15, and then the sleeve 15 will squeeze the arc surface of the ball 14, pushing the ball 14 into the tooth groove 17, and the position of the clamp handle 24 is limited, so that the clamp handle 24 and the connecting rod 6 are connected, so that multiple sets of clamp handles 24 can be installed above the connecting rod 6, and medical staff can use the clamp handles to 1 drives the connecting rod 6 to move, and is driven to move by the connecting rod 6, thereby driving multiple groups of clamp heads 2 3 to clamp the cervical opening synchronously, thereby improving the convenience of clamping. When it is necessary to place a hemostatic balloon in the uterine cavity, by pressing the fixing block 11 and the fixing block 2 13, the spring 12 is squeezed to contract and drive the sleeve 15 to move, so that the sleeve 15 is separated from the connecting rod 6 and the squeezing of the sleeve 15 is released, the clamp head 2 3 and the clamp handle 2 4 located in the middle can be disassembled, and the hemostatic balloon can be placed in the uterine cavity.

[0028] Embodiment 2:

[0029] See also Figure 1-7In this embodiment, the front ends of the clamp heads 1 and 2 are fixedly connected with a clamp head 10 in an annular structure, the adjacent sides of the two sets of clamp handles 1 are fixedly connected with the limited block 2 8, the adjacent surfaces of the two sets of limited blocks 2 8 are fixedly connected with the limited tooth blocks 9, and the two sets of limited tooth blocks 9 are arranged opposite to each other, and the inside of the clamp head 2 is provided with an insertion groove C near the connecting rod 6, and the inside of the insertion groove C is provided with a spring 2 18, one end of the spring 2 18 is connected to the clamp handle 1, and the other end of the spring 2 18 is connected to the clamp handle 1. The end of the clamp handle 1 is in conflict with the connecting rod 6, a spring 3 20 is arranged inside the clamp handle 1, and a slider 2 19 with a T-shaped structure is slidably connected to the side of the clamp handle 1 close to the spring 3 20, and the two ends of the spring 3 20 are respectively in conflict with the slider 2 19 and the clamp handle 1, and the surface of the slider 2 19 is fixedly connected with a limit block 5 with an L-shaped structure, and a limit groove 7 is provided on the side of the surface of the connecting rod 6 close to the limit block 5; the connecting rod 6 is hinged on the surface of the clamp handle 1, and when the connecting rod 6 needs to be stored, The connecting rod 6 is turned over and stored in the insertion groove A inside the clamp handle 1, and the spring 2 18 is squeezed to shrink. Then the slider 2 19 is pushed by the elastic force of the spring 3 20 to move the limit block 1 5 to limit the position of the connecting rod 6. The limit of the connecting rod 6 is released by pulling the limit block 1 5. The connecting rod 6 is slid out from the inside of the clamp handle 1 by the elastic force of the spring 2 18, and the connecting rod 6 can be opened. When the connecting rod 6 is opened, the limit block 1 5 is moved to insert the limit block 1 5 into the inside of the limit groove 7. The position of the connecting rod 6 can be limited to ensure that the connecting rod 6 is perpendicular to the clamp handle 1, and the stability of the opening of the connecting rod 6 is improved. The clamping head 10 can observe the clamping of cervical tissue when clamping the cervix. When the two clamp handles 1 are closed together, the limiting tooth blocks 9 on the two sets of limiting blocks 8 can be engaged and locked with each other, so that the clamping part at the front end of the clamp head 2 is kept in a clamped state. In this way, the clamping part can clamp the cervical tissue for several hours to prevent postpartum hemorrhage.

Then, the clamp handle 24 is placed above the connecting rod 6 according to the use requirements, and the position of the clamp head 23 is adjusted at the same time. After the adjustment is appropriate, the sleeve 15 is pushed to move by the elastic force of the spring 12 through the fixing block 213, and then the sleeve 15 squeezes the arc surface of the ball 14, pushing the ball 14 to be stuck in the tooth groove 17, so as to limit the position of the clamp handle 24 and make the clamp handle 24 and the clamp head 23 move. The connecting rod 6 is connected, so that multiple groups of clamp handles 2 4 can be installed above the connecting rod 6, and medical staff can drive the connecting rod 6 to move through the clamp handle 1, and then drive the multiple groups of clamp heads 2 3 to clamp the cervical opening synchronously through the connecting rod 6, thereby improving the convenience of clamping. When it is necessary to place a hemostatic balloon in the uterine cavity, by pressing the fixing block 11 and the fixing block 2 13 to squeeze the spring 12 to contract, and drive the sleeve 15 to move, so that the sleeve 15 is separated from the connecting rod 6, and the squeezing of the sleeve 15 is released, the clamp head 2 3 and the clamp handle 2 4 located in the middle can be disassembled, and the hemostatic balloon can be placed in the uterine cavity;

[0031] When the cervical forceps needs to be stored, the connecting rod 6 is flipped and stored in the insertion groove A inside the clamp handle 1, and the spring 2 18 is squeezed to contract. Then the slider 2 19 is pushed by the elastic force of the spring 3 20 to push the limit block 1 5 to move, limit the position of the connecting rod 6, and complete the storage of the connecting rod 6.

[0032] Through the above steps, by installing multiple sets of clamp handles 24 on the connecting rod 6, medical staff can drive the connecting rod 6 to move through the clamp handle 1, and drive the movement through the connecting rod 6, thereby driving multiple sets of clamp heads 23 to clamp the cervical opening synchronously, thereby improving the convenience of clamping. At the same time, by pressing the fixed block 11 and the fixed block 2 13 to squeeze the spring 12 to contract and drive the sleeve 15 to move, the sleeve 15 is separated from the connecting rod 6, and the squeezing of the sleeve 15 is released, the clamp head 23 and the clamp handle 24 located in the middle can be disassembled, which is convenient for placing a hemostatic balloon in the uterine cavity and reducing the time required for cervical clamp fixation during surgery.

[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
