DETAILED DESCRIPTION
[0024] The specific embodiments of the present invention will be described in detail below. It should be noted that the embodiments described here are only for illustration and are not intended to limit the present invention. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present invention.

Therefore, the phrases "in one embodiment", "in an embodiment", "an example" or "an example" appearing in various places throughout the specification do not necessarily refer to the same embodiment or example. In addition, particular features, structures or characteristics may be combined in one or more embodiments or examples in any suitable combination and / or sub-combination. In addition, it should be understood by those of ordinary skill in the art that the illustrations provided herein are for illustrative purposes and that the illustrations are not necessarily drawn to scale.
[0026] See also Figure 1The utility model provides an embodiment of a cervical hemostatic clamp, comprising: an upper arc-shaped splint 1, an upper clamp short handle 11, a lower arc-shaped splint 2, a lower clamp short handle 21 and a torque component, wherein the upper clamp short handle 11 is fixedly connected to one end of the upper arc-shaped splint 1, and the lower clamp short handle 21 is fixedly connected to one end of the lower arc-shaped splint 2, and the upper clamp short handle 11 and the lower clamp short handle 21 are rotatably connected through the torque component. When in use, the medical staff first pulls out the part of the cervix that needs to stop bleeding through the pliers, then pinches one end of the upper clamp short handle 11 and the lower clamp short handle 21, and then presses them toward each other so that the spacing between the upper arc-shaped splint 1 and the lower arc-shaped splint 2 increases accordingly, and when the upper arc-shaped splint 1 and the lower arc-shaped splint 2 are in the clamping position, the fingers are slowly released, and the spacing between the upper arc-shaped splint 1 and the lower arc-shaped splint 2 decreases accordingly, and finally the cervix is clamped to stop bleeding.
[0027] At the same time, since the clamping ends of the upper arc splint 1 and the lower arc splint 2 are designed to be arc-shaped, they can fit well with the surface of the cervix, increasing the clamping surface area. There is no need to use multiple oval forceps at the same time as when using oval forceps, thereby reducing the traction weight of the cervix and alleviating excessive traction on the cervix; and since the upper clamp short handle 11 and the lower clamp short handle 21 are both set as short handles, they will not block the vulva during use, which is convenient for subsequent wound treatment.
[0028] See also Figure 1 and Figure 4 In this embodiment, the clamping surfaces of the upper arc splint 1 and the lower arc splint 2 are both set to be arc plates that fit the curvature of the cervix, and the clamping surfaces of the upper arc splint 1 and the lower arc splint 2 cooperate with each other, and the ends of the upper arc splint 1 and the lower arc splint 2 away from the short handle of the upper clamp are set as arc blocks, so that the clamping surfaces of the upper arc splint 1 and the lower arc splint 2 can better fit the patient's cervical surface and achieve better hemostasis effect.
[0029] See also Figure 1 In this embodiment, a through hole 4 is provided in the middle of the upper arc splint 1 and the lower arc splint 2, so as to facilitate the long-term clamping of the cervix during use; if the upper arc splint 1 or the lower arc splint 2 is solid as a whole, the clamping part of the cervix may become necrotic or edematous if the clamping is too long; at the same time, when the uterine cavity is filled with a water bag, the water bag tube is passed through the gap between the limiting plate 5, the upper clamp short handle 11 and the lower clamp short handle 21, which can effectively prevent the water bag from slipping out, and there is no need to fix it by filling the vagina with too much gauze, which effectively reduces the discomfort of the parturient.
[0030] See also Figure 1In this embodiment, the upper arc splint 1 and the lower arc splint 2 are fixedly connected to the side close to each other with a protective gasket 3. The protective gasket 3 can be made of soft rubber material or sponge material. When the upper arc splint 1 and the lower arc splint 2 clamp the patient's cervical hemostasis, the upper arc splint 1 and the lower arc splint 2 do not directly contact the patient's cervical tissue. The protective gasket 3 plays an isolation and protection effect, thereby reducing damage to the cervix and the distending pain of the parturient.
[0031] See also Figure 1 In this embodiment, the torsion assembly includes a connecting rod and a torsion spring 7. The upper clamp short handle 11 and the lower clamp short handle 21 are rotatably connected by the connecting rod. The torsion spring 7 is sleeved on the connecting rod. One end of the torsion spring 7 is pressed against the upper clamp short handle 11, and the other end is pressed against the lower clamp short handle 21. When the medical staff slowly releases the fingers pressing on the upper clamp short handle 11 and the lower clamp short handle 21, the upper clamp short handle 11 and the lower clamp short handle 21 are reset under the elastic deformation of the torsion spring 7, so that the upper arc splint 1 and the lower arc splint 2 are abutted, which is convenient for clamping the cervix to stop bleeding during use.
[0032] See also Figure 1-2 The first and second limit blocks 51 are fixedly installed on the side of the limit plate 5 close to the first limit block 52, and the bottom of the first limit block 52 abuts against the top of one of the second limit blocks 51. When the cervix is clamped to stop bleeding, the limit plate 5 is rotated to press the lower surface of the first limit block 52 against the upper surface of one of the second limit blocks 51, and they are pressed against each other under the elastic deformation of the torsion spring 7, so as to achieve the effect of adjusting the angle between the upper clamp short handle 11 and the lower clamp short handle 21, thereby controlling the spacing between the upper arc splint 1 and the lower arc splint 2, that is, controlling the clamping force of the upper arc splint 1 and the lower arc splint 2 on the cervix, avoiding the situation that the clamping force is not enough to achieve the hemostasis effect, or the clamping force is too large to damage the cervix, or even cause necrosis of cervical tissue.
[0033] See also Figure 3In this embodiment, a clamping member is provided between the first limit block 52 and the second limit block 51, which can further prevent the first limit block 52 and the second limit block 51 from being separated from each other due to accidental touch. The second stop block 51 is then released from the engagement of the first stop block 52 and the second stop block 51 is then released from the engagement of the second stop block 51.
[0034] See also Figure 1 In this embodiment, one end of the upper clamp short handle 11 is fixedly connected to two ear plates, a fixing rod is fixedly connected between the two ear plates, and the limit plate is rotatably connected to the fixing rod. When no limiting is needed, the limit plate 5 is rotated so that the elastic card block 53 exits the card slot, that is, the first limit block 52 and the second limit block 51 are disengaged from each other, which is convenient for pressing the upper clamp short handle 11 and the lower clamp short handle 21 again; when limiting is needed, the limit plate 5 is rotated so that the elastic card block 53 is stuck in the card slot, that is, the first limit block 52 and the corresponding second limit block 51 are clamped with each other, so that the distance between the upper clamp short handle 11 and the lower clamp short handle 21 no longer changes, that is, the purpose of controlling the clamping force between the upper arc clamp plate 1 and the lower arc clamp plate 2 is achieved.
[0035] See also Figure 1 In this embodiment, the ends of the upper clamp short handle 11 and the lower clamp short handle 21 away from the upper arc-shaped clamp plate 1 are fixedly connected with anti-slip strips 6. Multiple anti-slip strips 6 can be provided according to actual conditions. When the medical staff presses the upper clamp short handle 11 and the lower clamp short handle 21, the fingers are placed on the anti-slip strips 6 to achieve an anti-slip effect, avoiding the situation in which the upper clamp short handle 11 and the lower clamp short handle 21 become slippery due to various liquids during use, which is not conducive to pressing.
[0036] The specific usage method of this embodiment is as follows:
[0037] When in use, the medical staff first pulls out the part of the cervix that needs to stop bleeding with the pliers, then pinches one end of the upper clamp short handle 11 and the lower clamp short handle 21, and then presses them toward each other so that the distance between the upper arc splint 1 and the lower arc splint 2 gradually increases. When the upper arc splint 1 and the lower arc splint 2 are in the clamping position, slowly release the fingers, then the distance between the upper arc splint 1 and the lower arc splint 2 decreases accordingly, and finally clamps the cervix to stop bleeding; then slightly rotate the limit plate 5 so that the elastic clamping block 53 is clamped into the clamping groove, that is, the first limit block 52 and the corresponding second limit block 51 are clamped to each other, so that the distance between the upper clamp short handle 11 and the lower clamp short handle 21 no longer changes, that is, the purpose of controlling the clamping force between the upper arc splint 1 and the lower arc splint 2 is achieved; finally, release the pliers, and the clamping of the cervix is completed.
[0038] When it is necessary to remove the cervical hemostatic clamp, the medical staff inserts their hand into the vagina, and then slightly rotates the limit plate 5 to make the elastic block 53 withdraw from the slot, that is, the first limit block 52 and the second limit block 51 are separated from each other, and then pinches one end of the upper clamp short handle 11 and the lower clamp short handle 21, and presses them toward each other, so that the distance between the upper arc splint 1 and the lower arc splint 2 gradually increases, and finally takes out the cervical hemostatic clamp.
[0039] In summary, the utility model makes the clamping force of the cervical hemostatic clamp adjustable through the cooperation of the upper arc clamp 1, the upper clamp short handle 11, the lower arc clamp 2, the lower clamp short handle 21, the limit plate 5, the first limit block 52, the second limit block 51 and the torque assembly, thereby achieving a better hemostatic effect and avoiding damage to the cervix due to excessive clamping force, or even causing necrosis of cervical tissue. Therefore, the utility model effectively overcomes various shortcomings in the prior art.
