Description

Technical Field

[0001] The invention relates to the technical field of neonates, in particular to a special forceps for neonates with umbilical cord edema. Background Art

[0002] Neonatal umbilical cord edema, commonly known clinically as a "watery umbilical cord," manifests as abnormal thickening of the Wharton's jelly within the umbilical cord. Wharton's jelly is a viscous, transparent, colloid substance that normally appears pale yellow. Its primary function is to protect the blood vessels within the umbilical cord. When the Wharton's jelly becomes pathologically thickened and filled with water, resulting in edema, it compresses the umbilical blood vessels. After delivery, the umbilical cord, along with the placenta, is separated from the mother. Medical staff typically cut and tie the cord within a few minutes.

[0003] At present, clinical practice uses two vascular clamps to clamp the two ends of the umbilical cord respectively, with the distance between the two clamps maintained at 3 cm, and then uses scissors to cut the umbilical cord in the middle of the two clamps. Next, the root of the umbilical cord and the surrounding area are disinfected with alcohol, and then a small rubber band is used to clamp it 1 cm away from the root of the umbilical cord, and finally the excess umbilical cord is cut off. However, some newborns are born with umbilical cord edema. After the umbilical cord edema, not only does the diameter increase, but the brittleness of its tissue also increases significantly. At this time, if the umbilical cord is clamped and squeezed directly with forceps, it is very easy to cause the umbilical cord to rupture. Therefore, the present invention provides a special forceps for neonatal umbilical cord edema to meet the needs. Summary of the Invention

[0004] The present invention provides a special clamp for neonatal umbilical cord edema. By providing a clamping component, it can be used to clamp the umbilical cord of a neonate with edema. Since some newborns are born with umbilical cord edema, the umbilical cord not only increases in diameter after edema, but also significantly increases the fragility of its tissue. Through the cooperation between the clamping components, it can adapt to edematous umbilical cords of different thicknesses. At the same time, it can also squeeze out the water in the Wharton's jelly at the clamped part of the edematous umbilical cord, reduce the fragility of the umbilical cord tissue after edema, and avoid umbilical cord rupture during clamping. In addition, after the umbilical cord is clamped, the device can also limit the position, so that the force applied to clamp the umbilical cord each time remains relatively stable, avoiding damage to the umbilical cord due to uneven force.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0009] Optionally, an airbag is clamped on the inner wall of the first clamping groove, the airbag is provided with a contact surface that contacts the outer wall of the umbilical cord, and the inner wall of the airbag is sleeved with a first skeleton.

[0010] Optionally, the two sides of the first skeleton are fixedly connected with a second skeleton respectively. There are six second skeletons in total, which are symmetrical in pairs, and each two form a group, divided into three groups. The three groups of second skeletons are distributed in an arc-shaped array, and a curved portion is provided on the second skeleton.

[0011] Optionally, one end of the two second skeletons in each group is fixedly connected to a first C-shaped elastic plate and a second C-shaped elastic plate respectively, and one end of the first C-shaped elastic plate and the second C-shaped elastic plate is fixedly connected to the same third skeleton.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by providing a clamping component, it can be used to clamp the umbilical cord of a newborn with edema. Since some newborns are born with umbilical cord edema, the umbilical cord not only increases in diameter after edema, but also significantly increases the fragility of its tissue.

At the same time, it can also squeeze out the water in the Wharton's jelly at the clamped part of the edematous umbilical cord, reduce the fragility of the tissue after edema, and avoid rupture of the umbilical cord during clamping. In addition, after clamping the umbilical cord, the device can also limit the position so that the force of clamping the umbilical cord each time remains relatively stable, avoiding damage to the umbilical cord due to uneven force.

[0018] By arranging the first frame, the second frame, the third frame, the first C-shaped elastic plate and the second C-shaped elastic plate in the clamping assembly, not only can the airbag be shaped, but the airbag can also be disassembled and cleaned after surgery, thereby improving the practicality of the airbag. In addition, it can also prevent the edematous umbilical cord from rupturing during clamping.

[0019] By incorporating a linkage plate, a trigger plate, and a pull cable within the clamping assembly, the pull cable allows the airbag seat to shift during the clamping process. This helps squeeze out moisture from the umbilical cord's swollen Huatong gel, preventing cord rupture during clamping. Furthermore, the linkage plate can be positioned to maintain the device's grip on the umbilical cord, eliminating the need for medical staff to constantly press the upper and lower clamp handles, thereby improving their work efficiency.

[0020] By arranging a bellows, an airbag, a vent tube and a first spring in the clamping assembly, the airbag can be inflated by pressing the upper and lower clamp handles to clamp the edematous umbilical cord. In addition, it can also adapt to edematous umbilical cords of different thicknesses and has high practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] like Figures 1 to 11 As shown, an embodiment of the present invention provides a special forceps for neonatal umbilical cord edema, comprising an upper clamp handle 1 and a lower clamp handle 101 hinged together by a hinge screw 108, a first limiting ring 106 is fixedly connected to the outer wall of one end of the hinge screw 108, one end of the upper clamp handle 1 and the lower clamp handle 101 are respectively fixedly connected to a clamping seat 2, one end of the clamping seat 2 is fixedly connected to three clamping protrusions 201 distributed in an arc-shaped array, the outer walls of the other ends of the two clamping seats 2 are respectively fixedly connected to second limiting rings 107, and the outer wall of the clamping seat 2 is provided with a first avoidance groove 204.

[0042] The clamping assembly is used to clamp the umbilical cord of a newborn with edema. The clamping assembly is connected to the clamping seat 2, the upper clamp handle 1 and the lower clamp handle 101 respectively. Specifically, the upper clamp handle 1 and the lower clamp handle 101 are hinged together by screws, and the upper clamp handle 1 and the lower clamp handle 101 are symmetrical about the central axis of the hinge screw 108. The upper clamp handle 1 and the lower clamp handle 101 are composed of two parts: an "S"-shaped metal plate and a rectangular plastic plate. The first limiting ring 106 is fixedly connected to the outer wall of one end of the hinge screw 108. The first limiting ring 106 is composed of two parts: a metal cylinder and a metal ring. The two clamping seats 2 are fixedly connected to one end of the "S"-shaped metal plate on the upper clamp handle 1 and the lower clamp handle 101 respectively. The clamping seat 2 is a semicircular metal plate. The three clamping protrusions 201 are fixedly connected to the end of the clamping seat 2 away from the first limiting ring 106. On the outer wall, it is distributed in an arc-shaped array, and the clamping protrusion 201 is a square metal plate with an arc. The two second limiting rings 107 are respectively fixedly connected to the outer walls of the two clamping seats 2 near one end of the first limiting ring 106. The two second limiting rings 107 are symmetrical about the central axis of the hinge screw 108. The second limiting ring 107 consists of a metal cylinder and a metal ring. The first avoidance groove 204 is opened on the outer wall of one end of the clamping seat 2 near the clamping protrusion 201. The first avoidance groove 204 is a square groove with an arc at one end. When the upper clamp handle 1 and the lower clamp handle 101 are pinched, the upper clamp handle 1 and the lower clamp handle 101 will displace toward each other with the hinge screw 108 as the center of the circle. At the same time, the two clamping bases will displace toward each other with the hinge screw 108 as the center of the circle under the action of the lever principle, forming a clamping phenomenon.

[0043] The clamping assembly provided by the present invention can be used to clamp the umbilical cord of a newborn with edema. Since some newborns are born with umbilical cord edema, the umbilical cord not only increases in diameter but also significantly increases in tissue fragility. Through the cooperation between the clamping assemblies, it can adapt to edematous umbilical cords of varying thicknesses. At the same time, it can also squeeze out the water in the Wharton's jelly at the clamped part of the edematous umbilical cord, reducing the fragility of the umbilical cord tissue after edema and preventing umbilical cord rupture during clamping. In addition, after clamping the umbilical cord, the device can also limit the position, so that the force applied to clamp the umbilical cord each time remains relatively stable, avoiding damage to the umbilical cord due to uneven force.

[0044] like Figures 1 to 11As shown, the clamping assembly includes three first sliding grooves 202 respectively opened on the inner wall of the clamping seat 2, a tension spring 203 is fixedly connected to the inner wall of the first sliding groove 202, one end of the tension spring 203 is fixedly connected to the airbag seat 3, a first clamping groove 302 is opened on the inner wall of the airbag seat 3, and second clamping grooves 303 are symmetrically opened on the inner walls on both sides of the clamping groove. An avoidance hole 304 is opened on the bottom inner wall of the first clamping groove 302, an airbag 4 is clamped on the inner wall of the first clamping groove 302, and the airbag 4 is provided with a contact surface 401 that contacts the outer wall of the umbilical cord.

[0045] Specifically, the clamping assembly includes three first sliding grooves 202 opened on the inner wall of the clamping seat 2, and the three first sliding grooves 202 are distributed in a circular arc array. The first sliding groove 202 is a straight groove with a "convex" shape at one end having an arc, and one end of the tension spring 203 is fixedly connected to the inner wall of the first sliding groove 202 close to the clamping protrusion 201. The tension spring 203 is disclosed in the prior art, so it will not be repeated. When the tension spring 203 is subjected to tension, it will deform along the direction of its bending. The three sliding protrusions 301 are fixedly connected to the other ends of the three tension springs 203. The sliding protrusion 301 is composed of two metal cylinders with different diameters, and the overall contour is "convex", which is adapted to the inner wall contour of the first sliding groove 202. Therefore, the sliding protrusion 301 can slide on the inner wall of the first sliding groove 202, and the three The ends of the sliding protrusions 301 away from the first sliding groove 202 are fixedly connected to the outer wall of the same airbag seat 3. The airbag seat 3 is a hollow semicircular plate of metal. The first clamping groove 302 is opened on the inner wall of the airbag seat 3. The first clamping groove 302 is a square groove body with an arc. The second clamping groove 303 is symmetrically opened on the inner walls on both sides of the first clamping groove 302. The second clamping groove 303 is a semicircular groove body with an arc. The avoidance hole 304 is opened on the bottom inner wall of the first clamping groove 302 near one end of the hinge screw 108. The avoidance hole 304 is a circular groove body. The airbag 4 is clamped on the inner wall of the first clamping groove 302. The airbag 4 is disclosed in the prior art, so it is not described in detail. The contact surface 401 is set on the outer wall of the airbag 4 that contacts the umbilical cord, which is used to clamp the edematous umbilical cord of the newborn.

[0046] The inner wall of the airbag 4 is sleeved with a first skeleton 5, and three groups of second skeletons 501 are fixedly connected to both sides of the first skeleton 5. There are six second skeletons 501 in total, which are symmetrical in pairs, and each two form a group, which are divided into three groups in total. The three groups of second skeletons 501 are distributed in an arc-shaped array, and a bending portion 505 is provided on the second skeleton 501. One end of the two second skeletons 501 in each group is fixedly connected to the first C-type elastic plate 503 and the second C-type elastic plate 502 respectively, and one end of the first C-type elastic plate 503 and the second C-type elastic plate 502 is fixedly connected to the same third skeleton 504.

[0047] Specifically, the first skeleton 5 is sleeved on the inner wall of the airbag 4. The first skeleton 5 is a plastic plate with a curvature. The six second skeletons 501 are divided into three groups. The two second skeletons 501 in each group are symmetrically fixedly connected to the outer inner walls on both sides of the first skeleton 5, and the three groups of second skeletons 501 are distributed in an arc array. The second skeleton 501 is a curved plastic plate. The curved portion 505 is arranged in the middle position of the second skeleton 501. The curved portion 505 is in a "C" shape with a curvature, and the contour of the curved portion 505 is adapted to the contour of the second snap-fitting groove 303 mentioned above, and can be snapped into the second snap-fitting groove 3 On the inner wall of 03, when the bending part 505 is subjected to force, it will deform along the direction of its bending. The second skeleton 501 in each group close to the clamping protrusion 201 has an end fixedly connected to one end of the first C-type elastic plate 503 at its end away from the first skeleton 5, and the second skeleton 501 in each group away from the clamping protrusion 201 has an end fixedly connected to one end of the second C-type elastic plate 502 at its end away from the first skeleton 5. The first C-type elastic plate 503 and the second C-type elastic plate 502 are both "C"-shaped plastic plates, but the volume of the first C-type elastic plate 503 is larger than that of the second C-type elastic plate 502.

[0048] When the first C-shaped elastic plate 503 and the second C-shaped elastic plate 502 are pinched at the same time, the first C-shaped elastic plate 503 will be subjected to force and deformed along the direction of its bending, and the second C-shaped elastic plate 502 will also be subjected to force and deformed along the direction of its bending. At this time, the two second skeletons 501 connected to the first C-shaped elastic plate 503 and the second C-shaped elastic plate 502 respectively will tilt toward the inside of the airbag 4, causing the two bent portions 505 to deform in the direction of the inside of the airbag 4 away from the end of the first skeleton 5, thereby releasing the restriction of the second clamping groove 303 on the second skeleton 501. At this time, the airbag 4 can be taken out of the first clamping groove 302, making it convenient for medical staff to disassemble and clean the airbag 4. One end of the third skeleton 504 is fixedly connected to the outer wall of the end of the first C-shaped elastic plate 503 away from the second skeleton 501. The other end of 504 is fixedly connected to the outer wall of the second C-shaped elastic plate 502 at one end away from the second skeleton 501. The third skeleton 504 is a stepped and curved plastic plate. The end close to the first C-shaped elastic plate 503 is higher than the end close to the second C-shaped elastic plate 502, and it descends step by step in three steps. In this way, during the clamping process, the contact surface 401 of the airbag 4 shaped by the third skeleton 504 will contact the outer wall of the umbilical cord in turn, and will squeeze the moisture in the Wharton's jelly in the umbilical cord to be clamped toward the second C-shaped elastic plate 502, so that the umbilical cord will not rupture due to edema, which will endanger the health of the newborn. The above structural setting can not only shape the airbag 4, but also disassemble and clean the airbag 4 after surgery, thereby improving the practicality of the airbag 4. In addition, it can also prevent the edematous umbilical cord from rupturing during clamping.

[0049] like Figures 1 to 11 As shown, the clamping assembly also includes a bellows 9 fixedly connected to the bottom outer wall of one end of the upper clamp handle 1, a first spring 901 is sleeved on the inner wall of the bellows 9, a vent hole 902 is opened on the top outer wall of the lower clamp handle 101, and a vent pipe 103 is fixedly connected to the outer wall of one side of the lower clamp handle 101. One end of the vent pipe 103 is divided into two and fixedly connected to the outer walls of the two air bags 4 respectively.

[0050] Specifically, the clamping assembly also includes a bellows 9, one end of which is fixedly connected to the bottom outer wall of the upper clamp handle 1 away from the clamping seat 2, and the other end is fixedly connected to the top outer wall of the lower clamp handle 101 away from the clamping seat 2. The bellows 9 is disclosed in the prior art, so it is not described in detail. The bellows 9 is made of rubber, and the vent 902 is opened on the top outer wall of the lower clamp handle 101 and is located inside the bellows 9. It is an "L"-shaped circular groove that passes through the outer wall of the side of the lower clamp handle 101 away from the first limit ring 106, and can discharge the gas in the bellows 9 when the bellows 9 is compressed. The first spring 901 is sleeved on the inner wall of the bellows 9, and the two ends are respectively connected to the upper clamp The handle 1 is connected to the outer wall of the lower clamp handle 101. When the first spring 901 is subjected to force, it will deform along the direction of its bending. The vent tube 103 is fixedly connected to the outer wall of the lower clamp handle 101 on one side of which the vent hole 902 is provided. The end of the vent tube 103 close to the bellows 9 is connected to the bellows 9 through the vent hole 902 opened on the lower clamp handle 101. The other end of the vent tube 103 is divided into two, respectively passing through the two avoidance holes 304 mentioned above, and fixedly connected to the outer wall of the airbag 4. When the medical staff pinches the upper clamp handle 1 and the lower clamp handle 101, the upper clamp handle 1 and the lower clamp handle 101, which are hinged together, will approach each other after being subjected to force at the end close to the bellows 9.

[0051] At this time, both ends of the bellows 9 will be under pressure and deform along the direction of its bending, and the gas in the bellows 9 will be discharged into the airbag 4 through the vent tube 103, so that the airbag 4 is inflated. The tightness of pinching the upper clamp handle 1 and the lower clamp handle 101 can be selected according to the thickness of the edematous umbilical cord. When the edematous umbilical cord is too thin, it can be pinched more tightly, and the airbag 4 will be filled with more gas, so that the relatively thin edematous umbilical cord can be clamped. On the contrary, when the edematous umbilical cord is too thick, it can be pinched more loosely, and the airbag 4 will be filled with less gas, so that the relatively thick edematous umbilical cord can be clamped. When the upper clamp handle 1 and the lower clamp handle 101 are no longer pinched, the first spring 901 will restore its deformation under the action of its own elasticity, pushing the upper clamp handle 1 and the lower clamp handle 101 to reset, and driving the bellows 9 to restore its deformation. In the process of restoring the deformation, the bellows 9 will draw the gas in the airbag 4 back into the bellows 9 through the ventilation tube 103, thereby canceling the clamping of the edematous umbilical cord. The above structural setting can inflate the airbag 4 by pressing the upper clamp handle 1 and the lower clamp handle 101 to clamp the edematous umbilical cord, and can also adapt to edematous umbilical cords of different thicknesses, and is highly practical.

[0052] like Figures 1 to 11 As shown, the clamping assembly also includes a semicircular movable buckle 102 fixedly connected to the outer wall of the bottom of the upper clamp handle 1, one end of the semicircular movable buckle 102 is screwed with a linkage plate 6, and the linkage plate 6 is respectively provided with a second sliding groove 601, a third sliding groove 602, a fourth sliding groove 603 and a circular hole groove 604, and a plurality of limiting teeth 605 are fixedly connected to the inner wall of the second sliding groove 601. A second avoidance groove 8 is provided on the outer wall of the bottom of the lower clamp handle 101, and an inner wall on one side of the second avoidance groove 8 A fifth sliding groove 801 is provided on it, and a second spring 803 is fixedly connected to the inner wall of one end of the fifth sliding groove 801, and a sliding circular plate 701 is fixedly connected to one end of the second spring 803, and a pull plate 7 is fixedly connected to the outer wall of one end of the sliding circular plate 701.

The circular ring buckle 104 is a plastic circular ring. One end of the cable 105 is fixedly connected to the outer wall of the circular ring buckle 104. The cable 105 is disclosed in the prior art, so it is not described in detail. The other end of the cable 105 passes through the first limiting ring 106 and is divided into two, respectively passing through the two second limiting rings 107, and respectively fixedly connected to the outer wall of the two airbag seats 3 away from the clamping protrusion 201. The cable 105 can pull the airbag seat 3 to slide on the inner wall of the first sliding groove 202.

[0054] Specifically, the second avoidance groove 8 is opened on the bottom outer wall of the lower clamp handle 101 and passes through the top outer wall of the clamp handle. The second avoidance groove 8 is a rectangular groove body, and its outline is adapted to the outline of the linkage plate 6. The linkage plate 6 can slide on the inner wall of the second avoidance groove 8. The two ends of the limiting column 802 are respectively fixedly connected to the middle position of the outer walls on both sides of the second avoidance groove 8. The limiting column 802 is a plastic cylinder, and its outline is adapted to the interval outline between the two limiting teeth 605. In conjunction with the limiting teeth 605, the linkage plate 6 sliding in the second avoidance groove 8 can be limited. The fifth sliding groove 801 is opened on the inner wall of the second avoidance groove 8 on one side close to the bellows 9. The fifth sliding groove 801 is a long circular groove. One end of the second spring 803 is fixedly connected to the inner wall of the fifth sliding groove 801 on one end close to the bellows 9 When the second spring 803 is subjected to force, it will deform along the direction of its bending, and the other end of the second spring 803 is fixedly connected to the outer wall of the sliding circular plate 701. The sliding circular plate 701 is composed of two parts, namely a circular plastic plate and a rectangular plastic plate that are adapted to the contour of the fifth sliding groove 801, so that the sliding circular plate 701 can slide on the inner wall of the fifth sliding groove 801, and the plate 7 is fixedly connected to the outer wall of one end of the part of the sliding circular plate 701 with the rectangular plastic plate.

[0055] When the medical staff pulls the trigger plate 7 in the direction of the bellows 9, the trigger plate 7 will drive the sliding circular plate 701 to move on the inner wall of the fifth sliding groove 801 toward the direction of the bellows 9. At this time, the second spring 803 will be squeezed by the sliding circular plate 701 and deformed along its bending direction. At the same time, the trigger plate 7 will pull the linkage plate 6 to move in the direction of the bellows 9. At this time, the limiting column 802 will slide out of the limiting tooth 605, releasing the limit on the linkage plate 6. At this time, the upper clamp handle 1 and the lower clamp handle 101 can be pressed. Driven by the upper clamp handle 1, the linkage plate 6 will move on the inner wall of the second avoidance groove 8 in the direction away from the upper clamp handle 1, and the ring will follow the linkage plate 6 to move and pull the cable 105, so that the airbag seat 3 fixedly connected to the other end of the cable 105 moves on the inner wall of the first sliding groove 202 When the index finger of the trigger plate 7 is released, the second spring 803 will restore its deformation under the action of its own elasticity, and push the sliding circular plate 701 to displace on the inner wall of the fifth sliding groove 801 in the direction away from the bellows 9, and drive the linkage plate 6 to displace, so that the limiting column 802 slides into the gap between the limiting teeth 605, and the linkage plate 6 is re-limited to keep the device in a clamping state. The above structural setting can displace the airbag seat 3 during the clamping process through the cable 105, which is beneficial to expel the moisture in the edematous umbilical cord's Chinese medicine glue and avoid umbilical cord rupture during clamping. The linkage plate 6 can also be limited to keep the device in a clamping state. There is no need for medical staff to press the upper clamp handle 1 and the lower clamp handle 101 at all times, thereby improving the work efficiency of medical staff.

[0056] The workflow of the technical solution provided by the present invention is as follows:

[0057] When in use, the medical staff aligns the clamping part of the device with the appropriate position on the edematous umbilical cord of the newborn, then pinches the upper clamp handle 1 and the lower clamp handle 101, and places the index finger on the trigger plate 7, first pulling the trigger plate 7, which will drive the sliding circular plate 701 to move on the inner wall of the fifth sliding groove 801 toward the direction of the bellows 9. At this time, the second spring 803 will be squeezed by the sliding circular plate 701 and deformed along its bending direction. At the same time, the trigger plate 7 will pull the linkage plate 6 toward the direction of the bellows 9. Displacement, at this time the limit column 802 will slide out from the limit tooth 605, releasing the limit on the linkage plate 6, at this time the upper clamp handle 1 and the lower clamp handle 101 can be pressed, and driven by the upper clamp handle 1, the linkage plate 6 will be displaced on the inner wall of the second avoidance groove 8 in the direction away from the upper clamp handle 1, and the ring will follow the displacement of the linkage plate 6 and pull the cable 105, so that the airbag seat 3 fixedly connected to the other end of the cable 105 will be displaced on the inner wall of the first sliding groove 202 in the direction away from the clamping protrusion 201.

[0058] At the same time, the upper clamp handle 1 and the lower clamp handle 101, which are hinged together, will move closer to each other at the ends close to the bellows 9 after being subjected to force. At this time, the two ends of the bellows 9 will be under pressure and will deform along the direction of its bending, and the gas in the bellows 9 will be discharged into the airbag 4 through the vent pipe 103, so that the airbag 4 is inflated. The contact surface 401 of the airbag 4, which is shaped by the third skeleton 504, will contact the outer wall of the umbilical cord in turn, and will push the moisture of the Wharton glue in the umbilical cord to be clamped toward the second C-shaped elastic plate. 502, and cooperates with the displacement of the clamping seat 2 to clamp the target edematous umbilical cord. At this time, when the index finger that pulls the trigger plate 7 is released, the second spring 803 will recover its deformation under the action of its own elasticity, and push the sliding circular plate 701 to move on the inner wall of the fifth sliding groove 801 in the direction away from the bellows 9, and drive the linkage plate 6 to move, so that the limiting column 802 slides into the gap between the limiting teeth 605, and re-limits the linkage plate 6 to keep the device in a clamping state.

[0059] Before clamping the edematous umbilical cord, the tightness of pinching the upper clamp handle 1 and the lower clamp handle 101 can be selected according to the thickness of the edematous umbilical cord. When the edematous umbilical cord is too thin, it can be pinched tighter, and the air bag 4 will be filled with more air, so that the relatively thin edematous umbilical cord can be clamped. On the contrary, when the edematous umbilical cord is too thick, it can be pinched looser, and the air bag 4 will be filled with less air, so that the relatively thick edematous umbilical cord can be clamped. After cutting off the edema, if it is necessary to cancel the clamping, the trigger plate 7 can be pulled again to release the limit on the linkage plate 6. The first spring 901 will recover its deformation under the action of its own elasticity, pushing the upper clamp handle 1 and the lower clamp handle 1 to push ... 01 is reset, and the two clamping seats 2 fixedly connected to one end of the upper clamp handle 1 and the lower clamp handle 101 are reset accordingly. As the upper clamp handle 1 is reset, the linkage plate 6 will be driven to move toward the direction of the upper clamp handle 1, and the pull cable 105 will no longer pull the airbag seat 3. The tension spring 203 will pull the airbag seat 3 to reset under the action of its own elasticity. As the upper clamp handle 1 and the lower clamp handle 101 are reset, the bellows 9 will be driven to restore the deformation. In the process of restoring the deformation, the bellows 9 will draw the gas in the airbag 4 back into the bellows 9 through the vent pipe 103, and cooperate with the reset of the clamping seat 2 to cancel the clamping of the edematous umbilical cord.
