Description

Technical Field

[0001] The present invention relates to the technical field of neonatology, and particularly relates to a special clamp for neonatal umbilical cord edema. Background Art

[0002] Neonatal umbilical cord edema, clinically known as "watery umbilicus", is manifested as abnormal thickening of Wharton's jelly in the umbilical cord. Wharton's jelly is a viscous transparent colloid, normally pale yellow in color, and its main function is to protect the blood vessels in the umbilical cord. When Wharton's jelly shows pathological thickening and is filled with water, presenting an edematous state, it will compress the umbilical blood vessels. After the neonate is delivered, the umbilical cord will be separated from the mother together with the placenta. Usually, medical staff will cut and ligate the umbilical cord within a few minutes.

[0003] Currently, clinically, two hemostatic forceps are used to clamp both ends of the umbilical cord respectively, and the distance between the two forceps is maintained at 3 cm. Then, the umbilical cord is cut with scissors at the middle position between the two forceps. Next, the root of the umbilical cord and its surrounding area are disinfected with alcohol, and then a small rubber band is used to clamp it at a distance of 1 cm from the umbilical root. Finally, the redundant part of the umbilical cord is cut off. However, some neonates are born with umbilical cord edema. After umbilical cord edema, not only does the diameter increase, but the brittleness of its tissue also increases significantly. At this time, if the forceps are directly used to clamp and squeeze the umbilical cord, it is extremely easy to cause the umbilical cord to rupture. Therefore, the present invention provides a special clamp 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 setting a clamping assembly, it can be used to clamp the umbilical cord of a neonate with edema. Since some neonates are born with umbilical cord edema, after umbilical cord edema, not only does the diameter increase, but the brittleness of its tissue also increases significantly. Through the cooperation between the clamping components, it can adapt to umbilical cords of different thicknesses with edema, and at the same time, it can also squeeze out the water in Wharton's jelly at the clamped part of the umbilical cord with edema, reducing the brittleness of the umbilical cord tissue after edema and avoiding umbilical cord rupture when clamping. In addition, after clamping the umbilical cord, the device can also perform limiting, so that the force for clamping the umbilical cord each time remains relatively stable, avoiding damage to the umbilical cord caused by uneven force.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A special clamp for neonatal umbilical cord edema, comprising an upper clamp handle and a lower clamp handle screwed together by a hinge screw. One end outer wall of the hinge screw is fixedly connected with a first limiting ring. One ends of the upper clamp handle and the lower clamp handle are respectively fixedly connected with clamping seats. One end of the clamping seat is fixedly connected with three clamping protrusions distributed in an arc array. Outer walls of the other ends of the two clamping seats are respectively fixedly connected with second limiting rings. One end outer wall of the clamping seat is provided with a first avoidance groove; a clamping assembly for clamping the umbilical cord of a neonate, and the clamping assembly is respectively connected with the clamping seat, the upper clamp handle and the lower clamp handle.

[0007] Optionally, the clamping assembly includes three first sliding grooves opened on the inner wall of the clamping seat, a corrugated pipe fixedly connected to the bottom outer wall of one end of the upper clamp handle, and a semi-circular movable buckle fixedly connected to the bottom outer wall of the upper clamp handle.

[0008] Optionally, a tension spring is fixedly connected to the inner wall of the first sliding groove. One end of the tension spring is fixedly connected with an airbag seat. A first clamping groove is opened on the inner wall of the airbag seat. Second clamping grooves are symmetrically opened on both inner walls of the clamping groove. An avoidance hole is opened on the bottom inner wall of the first clamping groove.

[0009] Optionally, an airbag is clamped on the inner wall of the first clamping groove. A contact surface in contact with the outer wall of the umbilical cord is arranged on the airbag. A first framework is sleeved on the inner wall of the airbag.

[0010] Optionally, second frameworks are respectively fixedly connected to both sides of the first framework. There are six second frameworks in total, which are pairwise symmetrical and divided into three groups with two in each group. The three groups of second frameworks are distributed in an arc array. A bending part is arranged on the second framework.

[0011] Optionally, a first C-shaped elastic plate and a second C-shaped elastic plate are respectively fixedly connected to one ends of the two second frameworks in each group. One ends of the first C-shaped elastic plate and the second C-shaped elastic plate are fixedly connected to the same third framework.

[0012] Optionally, a first spring is sleeved on the inner wall of the corrugated pipe. A linkage plate is screwed to one end of the semi-circular movable buckle. Second sliding grooves, third sliding grooves, fourth sliding grooves and circular hole grooves are respectively opened on the linkage plate.

[0013] Optionally, a plurality of limiting teeth are fixedly connected to the inner wall of the second sliding groove. A circular ring buckle is rotatably connected to the inner wall of the circular hole groove. A cable is fixedly connected to the outer wall of the circular ring buckle. One end of the cable is divided into two parts and respectively fixedly connected to the outer walls of the two airbag seats.

[0014] Optionally, a second avoidance groove is formed in the outer wall of the bottom of the lower pliers handle. A fifth sliding groove is formed in one inner wall of the second avoidance groove. A second spring is fixedly connected to one inner wall of one end of the fifth sliding groove. One end of the second spring is fixedly connected to a sliding circular plate. A wrench plate is fixedly connected to the outer wall of one end of the sliding circular plate.

[0015] Optionally, a ventilation hole is formed in the outer wall of the top of the lower pliers handle. An air pipe is fixedly connected to one outer wall of the lower pliers handle. One end of the air pipe is bifurcated and fixedly connected to the outer walls of the two air bags respectively.

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

[0017] In the above solution, by setting the clamping assembly, it can be used to clamp the umbilical cord of a newborn with edema. Since some newborns are accompanied by umbilical cord edema at birth, after the umbilical cord is edematous, not only does its diameter increase, but also the brittleness of its tissue increases significantly. Through the cooperation of the clamping components, it can adapt to umbilical cords of different thicknesses with edema. At the same time, the water in the Wharton's jelly at the clamped part of the edematous umbilical cord can be squeezed out, reducing the brittleness of the umbilical cord tissue after edema and avoiding umbilical cord rupture when clamping. In addition, after clamping the umbilical cord, the device can also perform limiting, so that the force for clamping the umbilical cord each time remains relatively stable, avoiding damage to the umbilical cord caused by uneven force.

[0018] By setting the first skeleton, the second skeleton, the third skeleton, the first C-shaped elastic plate and the second C-shaped elastic plate in the clamping assembly, not only can the air bag be shaped, but also the air bag can be disassembled and cleaned after the operation, improving the practicability of the air bag. In addition, it can also avoid the situation of umbilical cord rupture when clamping the edematous umbilical cord.

[0019] By setting the linkage plate, the wrench plate and the cable in the clamping assembly, the air bag seat can be displaced during the clamping process through the cable, which is beneficial to squeezing out the water in the Wharton's jelly of the edematous umbilical cord and avoiding umbilical cord rupture when clamping. In addition, the linkage plate can also be limited, so that the device keeps the clamping state of the umbilical cord, without the need for medical staff to constantly press the upper pliers handle and the lower pliers handle, thereby improving the work efficiency of medical staff.

[0020] By setting the corrugated pipe, the air bag, the air pipe and the first spring in the clamping assembly, the air bag can be inflated by pressing the upper pliers handle and the lower pliers handle to realize the clamping of the edematous umbilical cord. In addition, it can also adapt to umbilical cords of different thicknesses with edema and has high practicability. Description of the Drawings

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

[0042] The clamping assembly is used to clamp the umbilical cord of a newborn with edema. The clamping assembly is respectively connected to the clamping seat 2, the upper clamping handle 1 and the lower clamping handle 101. Specifically, the upper clamping handle 1 and the lower clamping handle 101 are hinged together by screws, and the upper clamping handle 1 and the lower clamping handle 101 are axisymmetric about the center of the hinge screw 108. The upper clamping handle 1 and the lower clamping handle 101 are both 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 a metal cylinder and a metal ring. The two clamping seats 2 are respectively fixedly connected to the ends of the upper clamping handle 1 and the lower clamping handle 101 with the "S"-shaped metal plate. The clamping seat 2 is a semi-circular metal plate. Three clamping protrusions 201 are fixedly connected to the outer wall of the end of the clamping seat 2 away from the first limiting ring 106, and are distributed in an arc array. The clamping protrusions 201 are square metal plates with a radian. Two second limiting rings 107 are respectively fixedly connected to the outer walls of the two clamping seats 2 near the first limiting ring 106. The two second limiting rings 107 are axisymmetric about the center of the hinge screw 108. The second limiting ring 107 is composed of a metal cylinder and a metal ring. The first avoidance groove 204 is opened on the outer wall of the end of the clamping seat 2 near the clamping protrusion 201. The first avoidance groove 204 is a square groove with a radian at one end. When the upper clamping handle 1 and the lower clamping handle 101 are pinched, the upper clamping handle 1 and the lower clamping handle 101 will displace towards each other with the hinge screw 108 as the center. At the same time, the two clamping bases will displace towards each other with the hinge screw 108 as the center 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, after the umbilical cord becomes edematous, not only does its diameter increase, but also the brittleness of its tissue significantly increases. Through the cooperation of the clamping assemblies, it can adapt to umbilical cords of different thicknesses with edema. 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 brittleness of the umbilical cord tissue after edema, and avoid umbilical cord rupture when clamping. In addition, after the umbilical cord is clamped, the device can also perform limiting to keep the force for clamping the umbilical cord relatively stable each time, and avoid damage to the umbilical cord caused by uneven force.

[0044] Such as Figures 1 to 11As shown in the figure, 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 an airbag seat 3. A first clamping groove 302 is opened on the inner wall of the airbag seat 3. Second clamping grooves 303 are symmetrically opened on both inner walls 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. The airbag 4 is provided with a contact surface 401 that contacts the outer wall of the umbilical cord.

[0045] Specifically, the three first sliding grooves 202 included in the clamping assembly are opened on the inner wall of the clamping seat 2. The three first sliding grooves 202 are arranged in an arc array. The first sliding groove 202 is a straight groove in a "convex" shape with a curved end. One end of the tension spring 203 is fixedly connected to the inner wall of the first sliding groove 202 near the clamping protrusion 201. Since the tension spring 203 is publicly known in the prior art, it will not be elaborated here. When the tension spring 203 is subjected to a tensile force, it will deform along its bent direction. 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 in a "convex" shape, 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. One ends of the three sliding protrusions 301 far from the first sliding groove 202 are all fixedly connected to the outer wall of the same airbag seat 3. The airbag seat 3 is a metal hollow semi-circular plate. 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 a curvature. The second clamping grooves 303 are symmetrically opened on both inner walls of the first clamping groove 302. The second clamping groove 303 is a semi-circular groove body with a curvature. The avoidance hole 304 is opened on the bottom inner wall of the first clamping groove 302 near 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. Since the airbag 4 is publicly known in the prior art, it will not be elaborated here. The contact surface 401 is arranged on the outer wall of the airbag 4 in contact with the umbilical cord, and is used to clamp the edematous umbilical cord of the newborn.

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

[0047] Specifically, the first framework 5 is sleeved on the inner wall of the airbag 4. The first framework 5 is a plastic plate with a curvature. The six second frameworks 501 are divided into three groups. Two second frameworks 501 in each group are symmetrically and fixedly connected to the outer inner walls on both sides of the first framework 5, and the three groups of second frameworks 501 are distributed in an arc array. The second framework 501 is an arc-shaped plastic plate. The bending part 505 is arranged in the middle position of the second framework 501. The bending part 505 is in a "C" shape with a curvature, and the contour of the bending part 505 is adapted to the contour of the second clamping groove 303 mentioned above and can be clamped on the inner wall of the second clamping groove 303. When the bending part 505 is stressed, it will deform along its bending direction. One end of the first C-shaped elastic plate 503 is fixedly connected to the end of the second framework 501 in each group that is close to the clamping protrusion 201 and away from the first framework 5, while one end of the second C-shaped elastic plate 502 is fixedly connected to the end of the second framework 501 in each group that is away from the clamping protrusion 201 and away from the first framework 5. Both the first C-shaped elastic plate 503 and the second C-shaped elastic plate 502 are plastic plates in a "C" shape, but the volume of the first C-shaped elastic plate 503 is larger than that of the second C-shaped elastic plate 502.

[0048] When the first C-shaped elastic plate 503 and the second C-shaped elastic plate 502 are pinched simultaneously, the first C-shaped elastic plate 503 will be stressed and deform along its bending direction, and the second C-shaped elastic plate 502 will also be stressed and deform along its bending direction. At this time, the two second frameworks 501 connected to the first C-shaped elastic plate 503 and the second C-shaped elastic plate 502 respectively will tilt towards the inside of the airbag 4, causing the ends of the two bending parts 505 away from the first framework 5 to deform towards the inside of the airbag 4, releasing the limit of the second clamping groove 303 on the second framework 501. At this time, the airbag 4 can be taken out from the first clamping groove 302, which is convenient for medical staff to disassemble, assemble and clean the airbag 4. One end of the third framework 504 is fixedly connected to the outer wall of the end of the first C-shaped elastic plate 503 away from the second framework 501, and the other end of the third framework 504 is fixedly connected to the outer wall of the end of the second C-shaped elastic plate 502 away from the second framework 501. The third framework 504 is a stepped and arc-shaped plastic plate, and its end close to the first C-shaped elastic plate 503 is higher than the end close to the second C-shaped elastic plate 502, descending step by step in a three-level stepped shape. In this way, during the clamping process, the contact surface 401 of the airbag 4 shaped by the third framework 504 will sequentially contact the outer wall of the umbilical cord, and the moisture of the Wharton's jelly in the umbilical cord to be clamped will be squeezed out towards the direction of the second C-shaped elastic plate 502, preventing the rupture of the edematous umbilical cord and endangering the health of the newborn. The above structural settings can not only shape the airbag 4, but also disassemble and clean the airbag 4 after the operation, improving the practicability of the airbag 4. In addition, it can also prevent the rupture of the edematous umbilical cord during clamping.

[0049] As shown Figures 1 to 11 in the figure, the clamping assembly further includes a corrugated pipe 9 fixedly connected to the bottom outer wall of one end of the upper clamping handle 1. A first spring 901 is sleeved on the inner wall of the corrugated pipe 9. An air vent 902 is opened on the top outer wall of the lower clamping handle 101. A ventilation pipe 103 is fixedly connected to the outer wall of one side of the lower clamping handle 101. One end of the ventilation pipe 103 is bifurcated and fixedly connected to the outer walls of two air bags 4 respectively.

[0050] Specifically, one end of the corrugated pipe 9 included in the clamping assembly is fixedly connected to the bottom outer wall of the upper clamping handle 1 away from the clamping seat 2, and the other end is fixedly connected to the top outer wall of the lower clamping handle 101 away from the clamping seat 2. The corrugated pipe 9 is publicly known in the prior art, so it will not be elaborated here. The corrugated pipe 9 is made of rubber. The air vent 902 is opened on the top outer wall of the lower clamping handle 101 and is located inside the corrugated pipe 9, in the shape of an "L"-shaped circular groove body, and penetrates out from the outer wall of the lower clamping handle 101 on the side away from the first limit ring 106, so that the gas inside the corrugated pipe 9 can be exported when the corrugated pipe 9 is compressed. The first spring 901 is sleeved on the inner wall of the corrugated pipe 9, and the two ends are respectively connected to the outer walls of the upper clamping handle 1 and the lower clamping handle 101. When the first spring 901 is stressed, it will deform along its bending direction. The ventilation pipe 103 is fixedly connected to the outer wall of the lower clamping handle 101 where the air vent 902 is provided. One end of the ventilation pipe 103 close to the corrugated pipe 9 is communicated with the corrugated pipe 9 through the air vent 902 opened on the lower clamping handle 101. The other end of the ventilation pipe 103 is bifurcated and respectively passes through the two avoidance holes 304 mentioned above and is fixedly connected to the outer wall of the air bag 4. When the medical staff pinches the upper clamping handle 1 and the lower clamping handle 101, after the upper clamping handle 1 and the lower clamping handle 101 hinged together are stressed, the ends close to the corrugated pipe 9 will approach each other.

[0051] At this time, the two ends of the corrugated pipe 9 will be under pressure and will deform along its bending direction, and the gas inside the corrugated pipe 9 will be discharged into the air bag 4 through the ventilation pipe 103, so that the air bag 4 is inflated. The tightness of pinching the upper clamping handle 1 and the lower clamping 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 tightly, and the more gas is filled in the air bag 4, and the relatively thin edematous umbilical cord can be clamped. On the contrary, when the edematous umbilical cord is too thick, it can be pinched loosely, and the less gas is filled in the air bag 4, and the relatively thick edematous umbilical cord can be clamped. When the upper clamping handle 1 and the lower clamping handle 101 are no longer pinched, the first spring 901 will recover its deformation under the action of its own elasticity, push the upper clamping handle 1 and the lower clamping handle 101 to reset, and drive the corrugated pipe 9 to recover its deformation. During the process of the corrugated pipe 9 recovering its deformation, the gas in the air bag 4 will be pumped back into the corrugated pipe 9 through the ventilation pipe 103, and the clamping of the edematous umbilical cord will be cancelled. The above structural settings can inflate the air bag 4 by pressing the upper clamping handle 1 and the lower clamping handle 101 to clamp the edematous umbilical cord, and can also adapt to edematous umbilical cords of different thicknesses, with high practicability.

[0052] As shown Figures 1 to 11 in the figure, the clamping assembly further includes a semi-circular movable buckle 102 fixedly connected to the outer wall of the bottom of the upper clamping handle 1. One end of the semi-circular movable buckle 102 is screwed with a linkage plate 6. 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. 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 clamping handle 101. A fifth sliding groove 801 is provided on one inner wall of the second avoidance groove 8. A second spring 803 is fixedly connected to one inner wall of the fifth sliding groove 801. One end of the second spring 803 is fixedly connected to a sliding circular plate 701. A wrench plate 7 is fixedly connected to the outer wall of one end of the sliding circular plate 701. A circular ring buckle 104 is rotatably connected to the inner wall of the circular hole groove 604. A cable 105 is fixedly connected to the outer wall of the circular ring buckle 104. One end of the cable 105 is bifurcated and fixedly connected to the outer walls of the two airbag seats 3 respectively.

[0053] Specifically, the semi-circular movable buckle 102 included in the clamping assembly is fixedly connected to the middle position of the outer wall of the bottom of the upper clamping handle 1. The semi-circular movable buckle 102 is a rectangular plastic plate with a curved end. The linkage plate 6 is screwed to the curved end of the semi-circular movable buckle 102 through a screw. The linkage plate 6 is a rectangular plastic plate with curved ends. The second sliding groove 601 is provided at the central position of the outer wall of the linkage plate 6 and is a rectangular groove body with curved ends. A plurality of limiting teeth 605 are fixedly connected to the inner wall of the second sliding groove 601 close to the corrugated pipe 9 and are distributed in a linear array. The limiting teeth 605 are dog-tooth-shaped plastic plates. The third sliding groove 602 is provided on the outer wall of the linkage plate 6 close to one end of the semi-circular movable buckle 102. The third sliding groove 602 is an arc-shaped groove body with curved ends, and its contour is adapted to the contour of the screw screwed on the semi-circular movable buckle 102. Therefore, the semi-circular movable buckle 102 can slide on the inner wall of the third sliding groove 602. The fourth sliding groove 603 is provided on the outer wall of the linkage plate 6 close to the corrugated pipe 9. The fourth sliding groove 603 is a rectangular groove body with curved ends. The circular hole groove 604 is provided on the outer wall of the linkage plate 6 far from one end of the semi-circular movable buckle 102. The circular hole groove 604 is a circular groove body. The circular ring buckle 104 is rotatably connected to the inner wall of the circular hole groove 604. The circular ring buckle 104 is a plastic ring. One end of the cable 105 is fixedly connected to the outer wall of the circular ring buckle 104. The cable 105 is publicly known in the prior art, so it will not be described in detail. The other end of the cable 105 passes through the first limiting ring 106 and is bifurcated, passes through the two second limiting rings 107 respectively, and is fixedly connected to the outer walls of the two airbag seats 3 on the side far 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 pliers handle 101 and penetrates out from the top outer wall of the pliers handle. The second avoidance groove 8 is a rectangular groove body, and its contour is adapted to the contour 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 limit post 802 are respectively fixedly connected to the middle positions of the outer walls on both sides of the second avoidance groove 8. The limit post 802 is a plastic cylinder, and its contour is adapted to the interval contour between the two limit teeth 605. Cooperating with the limit 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 close to the corrugated pipe 9. The fifth sliding groove 801 is a circular long groove. One end of the second spring 803 is fixedly connected to the inner wall of the fifth sliding groove 801 close to the corrugated pipe 9. When the second spring 803 is stressed, it will deform along its bent direction. 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 adapted to the contour of the fifth sliding groove 801 and a rectangular plastic plate. In this way, the sliding circular plate 701 can slide on the inner wall of the fifth sliding groove 801. The wrench plate 7 is fixedly connected to one end outer wall of the sliding circular plate 701 with the rectangular plastic plate part. The wrench plate 7 is composed of a rectangular plastic plate with a curved end and an arc-shaped plastic plate. One end of the wrench plate 7 far from the arc-shaped plastic plate is screwed to the fourth sliding groove 603 through a screw, and the contour of the screwed screw is adapted to the contour of the fourth sliding groove 603. Therefore, the wrench plate 7 can slide on the inner wall of the fourth sliding groove 603

[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 to release 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 move with 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 moves on the inner wall of the first sliding groove 202 The airbag seat 3 is displaced in the direction away from the clamping protrusion 201. When the index finger of the pull 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 interval of the limiting tooth 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 through the cable 105 during the clamping process, which is beneficial to expel the moisture in the umbilical cord Zhongtong glue to avoid umbilical cord rupture during clamping. The linkage plate 6 can also be limited to keep the device in a clamping state. Medical staff do not need to press the upper clamp handle 1 and the lower clamp handle 101 all the time, 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 pulls the trigger plate 7, and 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 in the direction of its bending. 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, and 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 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 move with 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] Meanwhile, after the force is applied to the hinged upper pliers handle 1 and lower pliers handle 101, the ends close to the bellows 9 will approach each other. At this time, both ends of the bellows 9 will be subjected to pressure, and it will deform along its bending direction, and the gas inside the bellows 9 will be discharged into the airbag 4 through the air pipe 103, inflating the airbag 4. The contact surface 401 shaped by the third skeleton 504 on the airbag 4 will sequentially contact the outer wall of the umbilical cord, and squeeze the moisture of the Wharton's jelly in the umbilical cord to be clamped towards the direction of the second C-shaped elastic plate 502, and cooperate with the displacement of the clamping seat 2 to clamp the target edematous umbilical cord. At this time, when the index finger pressing 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 away from the bellows 9 on the inner wall of the fifth sliding groove 801, and drive the linkage plate 6 to displace, so that the limit post 802 slides into the interval of the limit teeth 605 to re-limit the linkage plate 6 and keep the device in a clamping state.

[0059] Before clamping the edematous umbilical cord, the tightness of pinching the upper pliers handle 1 and lower pliers 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 more gas is filled in the airbag 4, and 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 less gas is filled in the airbag 4, and the relatively thick edematous umbilical cord can be clamped. After cutting the edema, if the clamping needs to be cancelled, the trigger plate 7 can be pulled again to release the limit on the linkage plate 6. The first spring 901 will restore its deformation under the action of its own elasticity, and push the upper pliers handle 1 and lower pliers handle 101 to reset. The two clamping seats 2 fixedly connected to one end of the upper pliers handle 1 and lower pliers handle 101 follow to reset. With the reset of the upper pliers handle 1, the linkage plate 6 will be driven to displace towards the upper pliers handle 1, and the 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. With the reset of the upper pliers handle 1 and lower pliers handle 101, the bellows 9 will be driven to restore its deformation. During the process of the bellows 9 restoring its deformation, the gas in the airbag 4 will be pumped back into the bellows 9 through the air pipe 103, and cooperate with the reset of the clamping seat 2 to cancel the clamping of the edematous umbilical cord.
