Description

Technical Field

[0001] The present invention relates to the field of umbilical cord ligation, and particularly to an umbilical cord ligation device. Background Art

[0002] After the fetus is born, the umbilical cord needs to be ligated to prevent infection.

[0003] In the prior art, umbilical cord clips and valve cores are usually used for ligation.

[0004] For the umbilical cord clip method, an umbilical cord clip will be left on the baby's belly after use. However, since the baby's skin is very delicate and the plastic umbilical cord clip is relatively hard, it will stick tightly and easily scratch the skin under the action of gravity. At the same time, the current common postnatal training for babies at home and abroad is swimming. After swimming, the body needs to be wiped and clothes need to be changed. It is very inconvenient to have a relatively large and heavy foreign object on the umbilical cord.

[0005] For the valve core ligation method, the valve core needs to be manually sleeved on the hemostat, the umbilical cord is clamped with the hemostat, and then the valve core is pulled onto the umbilical cord by a silk thread. The valve core is usually a rubber ring. To ensure that the silk thread can pull the valve core, the contraction force of the valve core should not be too large, resulting in a risk of blood splashing. Summary of the Invention

[0006] The present invention aims to provide an umbilical cord ligation device that can not only avoid scratching the skin by the umbilical cord clip but also reduce the risk of blood splashing.

[0007] To achieve the above object, the present invention adopts the following technical solution: An umbilical cord ligation device includes an umbilical cord clip and two clamping plates. The umbilical cord clip includes two clamping arms. One ends of the two clamping arms are rotatably connected, and the other ends of the two clamping arms are clamped. At least one rotating cylinder is rotatably connected to each clamping arm, and the clamping arm passes through the rotating cylinder along the length direction; the clamping plates are clamped on both sides of the umbilical cord, the clamping arms are clamped on the clamping plates and provide pressure for the clamping plates, and the clamping plates pass through between the two clamping arms; A receiving area is provided on the clamping plate. After pulling the valve core into the receiving area, the clamping arms are pushed to move away from the navel direction on the clamping plate. After the clamping arms pass through the receiving area, the valve core is continuously pulled to the end of the umbilical cord.

[0008] The core idea of this solution is: Use both the valve core and the umbilical cord clip for ligation. In the early stage, mainly the umbilical cord clip plays a role. After a period of time when the risk of blood splashing is reduced, the umbilical cord clip is preferably removed first to avoid scratching the skin by the umbilical cord clip; in the later stage, mainly the valve core plays a role.

[0009] The problem derived from the core idea: Since the umbilical cord clamp is mainly used to prevent blood splashing in the early stage, it is necessary to clamp the umbilical cord with the umbilical cord clamp first and then cut the umbilical cord. However, due to the presence of the umbilical cord clamp, the valve core cannot be pulled to the end of the umbilical cord close to the navel, which can easily cause the valve core to loosen. Especially after the umbilical cord clamp is removed in the later stage, the umbilical cord between the valve core and the navel will shake, further increasing the risk of the valve core loosening.

[0010] The solution of this scheme: This scheme improves the umbilical cord clamp by rotating a drum on the clamp arm and adding a splint between the clamp arm and the umbilical cord, so that the umbilical cord clamp can move on the splint after clamping the umbilical cord. After the two splints clamp the umbilical cord, they can pass through the valve core, so that the valve core passes through the clamping position to reach the end of the umbilical cord. Specifically, the umbilical cord clamp clamps the umbilical cord through the splint, and the accommodating area is located on the side of the splint away from the navel. One end of the splint is located at the end of the umbilical cord, and the other end passes through the umbilical cord clamp and reserves space for the umbilical cord clamp to move upward, so that the umbilical cord clamp can pass through the accommodating area; cut off the excess umbilical cord, pass the silk thread through the valve core, put the valve core on the two splints, pull the valve core to the accommodating area through the silk thread, push the clamp arm through the accommodating area, continue to pull the valve core to the end of the umbilical cord through the silk thread, and push the umbilical cord clamp close to the navel.

[0011] Furthermore, the accommodating area is a strip groove on the splint, and the strip groove is used to accommodate the valve core and ensure that the rotating drum passes smoothly.

[0012] Furthermore, the splint is in the shape of an elongated strip, and a strip-shaped protrusion is provided in the length direction of the splint; and an annular groove matching the strip-shaped protrusion is provided on the rotating drum.

[0013] Furthermore, the opposite sides of the two splints are arc-shaped.

[0014] Furthermore, the invention also includes a docking device, which includes an outer tube, an inner rod is provided in the outer tube, a valve core is sleeved on the inner rod, a silk thread is passed through the valve core, the silk thread is used to pull the valve core to slide on the inner rod, and a clamping claw is provided at the lower end of the inner rod; In the initial state, the clamping jaws are open and extend out of the lower end of the outer cylinder; The inner rod moves upward relative to the outer tube, and the lower end of the outer tube pushes the clamping claws inward to grasp the upper ends of the two splints, and the silk thread pulls the valve core to slide through the clamping claws.

[0015] Furthermore, a strip-shaped notch is vertically provided on the side of the outer tube, and the lower end of the strip-shaped notch passes through the bottom of the outer tube; When the wire pulls the valve core, the wire passes through the strip-shaped notch.

[0016] Furthermore, the upper end of the inner rod passes through the upper end of the outer tube and is provided with an end head, the radius of the end head is larger than the inner diameter of the outer tube; the upper part of the inner rod and the inner side of the outer tube are threadedly connected.

[0017] Further, the inner rod includes an upper inner rod and a lower inner rod connected by threads. The upper inner rod is threadedly connected to the inner side of the outer cylinder. The outer diameter of the lower inner rod is smaller than that of the upper inner rod. The valve core is sleeved on the lower inner rod.

[0018] Further, a linear motor is provided at the upper end of the outer cylinder, and the output shaft of the linear motor is connected to the upper end of the inner rod.

[0019] Further, the clamping jaws include a plurality of elastic rods arranged circumferentially. The upper ends of the elastic rods are all connected to the lower end of the inner rod, and at least one inward bending is provided on the elastic rods.

[0020] The present solution also has the following effects: 1. Through the cooperation of the strip-shaped protrusions and the circumferential grooves, guidance is carried out when the rotating cylinder moves, preventing the clamping plates from rotating and tilting, which may lead to a reduction in the clamping effect, thus avoiding blood splashing.

[0021] 2. The opposite sides of the two clamping plates are arc-shaped to facilitate fitting the surface of the umbilical cord. And since the umbilical cord clip will be removed in advance, mainly the valve core plays a ligation role in the later stage, so there is no need to consider the problem that the arc-shaped cross-section cannot be tightly clamped after the umbilical cord shrinks.

[0022] 3. The docking device is mainly used to facilitate the installation of the valve core. Multiple valve cores can be sleeved on the inner rod of the docking device in advance to improve the operation efficiency. A strip-shaped notch is provided on the outer cylinder to ensure the smoothness when pulling the silk thread, further increasing the operation efficiency.

[0023] 4. After cutting the umbilical cord, the outer cylinder is pushed to make the clamping jaws grip the umbilical cord and the two clamping plates, completing the docking of the docking device and the clamping plates. After the clamping jaws are tightened, the outer diameter of the clamping jaws shrinks to facilitate the passage of the valve core through the clamping jaws, so that the valve core is sleeved on the two clamping plates.

[0026] Example 1 Example 1 is basically as Figure 1 - Figure 11 shown: An umbilical cord ligation device includes an umbilical cord clip 1, a docking device 2 and two splints 3; As Figure 1 shown, the umbilical cord clip 1 includes a U-shaped part 11 and two clamping arms. The left ends of the two clamping arms are both connected to the U-shaped part 11. The U-shaped part 11 is made of an elastic material. Under the action of an external force, the U-shaped part 11 can drive the left ends of the two clamping arms to rotate relative to each other, and the other ends of the two clamping arms are clamped. The clamping method is the same as the clamping method of the umbilical cord clip 1 in the prior art. Figure 1 The clamping method in is a simplified schematic diagram. A snap component 13 is integrally formed at the right end of one clamping arm, and a slot component 14 is integrally formed at the right end of the other clamping arm. The snap component 13 is used to be clamped with the slot component 14; Two clamping plates 3 are used to clamp the umbilical cord 4. The clamping arms are clamped on the clamping plates 3 and provide pressure for the clamping plates 3. The clamping plates 3 are both strip-shaped. The opposite sides of the two clamping plates 3 are arc-shaped. The widths of the clamping plates 3 are both smaller than the length of the rotating cylinder 12. The two clamping plates 3 pass through between the rotating cylinders 12 of the two clamping arms. The clamping plates 3 are both perpendicular to the rotating cylinder 12. A strip-shaped groove 31 is provided in the middle of the clamping plate 3 along the width direction. The strip-shaped groove 31 is an accommodating area for accommodating the valve core 5.

[0027] As Figure 2 , Figure 3 , Figure 4 shown, the docking device 2 includes an outer cylinder 21. A strip-shaped notch 22 is vertically provided on the side of the outer cylinder 21. The lower end of the strip-shaped notch 22 penetrates through the bottom of the outer cylinder 21. An inner rod is inserted into the outer cylinder 21. The inner rod includes an upper inner rod 23 and a lower inner rod 24 which are threadedly connected. The upper inner rod 23 is threadedly connected to the inner side of the outer cylinder 21. The outer diameter of the lower inner rod 24 is smaller than the outer diameter of the upper inner rod 23. A plurality of valve cores 5 are sleeved on the upper inner rod 23. A silk thread 25 is inserted into each valve core 5. The upper end of the upper inner rod 23 passes through the upper end of the outer cylinder 21 and is integrally formed with a head 26. The radius of the head 26 is larger than the inner diameter of the outer cylinder 21. The upper inner rod 23 is threadedly connected to the inner side of the outer cylinder 21. A clamping claw 27 is provided at the lower end of the lower inner rod 24. The clamping claw 27 includes a plurality of elastic rods arranged circumferentially. The upper ends of the elastic rods are integrally formed with the lower end of the inner rod. The elastic rods are provided with inward bends. The side close to the circle is the inner side.

[0028] The silk thread 25 is used to pull the valve core 5 to slide on the lower inner rod 24 and the clamping plate 3; In this embodiment, a method for using an umbilical cord 4 ligation device is as follows: 1. As Figure 5 shown, the lower end of the umbilical cord 4 is the end close to the navel. The umbilical cord clip 1 clamps the umbilical cord 4 through the clamping plate 3. The accommodating area on the clamping plate 3 is located on the upper side of the clamping plate 3. The lower end of the clamping plate 3 is located at the end of the umbilical cord 4. It passes through the umbilical cord clip 1 and leaves an upward movement space for the umbilical cord clip 1 to facilitate the umbilical cord clip 1 to pass through the accommodating area smoothly; 2. As Figure 6 shown, cut off the redundant umbilical cord 4; 3. As Figure 7 shown, align the docking device 2 with the umbilical cord 4 fracture. In the initial state, the clamping claw 27 is opened, and the clamping claw 27 extends out of the lower end of the outer cylinder 21; 4. As Figure 8 shown, hold the head 26 and rotate the outer cylinder 21 to make the outer cylinder 21 move downward relative to the inner rod. The lower end of the outer cylinder 21 pushes the clamping claw 27 to tightly grasp the upper ends of the two clamping plates 3 inward; 5. As Figure 9 shown, pull up the silk thread 25 of the lowermost valve core 5 to make the silk thread 25 pass through the strip-shaped notch 22. The silk thread 25 pulls the valve core 5 to slide over the lower inner rod 24 and the clamping claw 27, and finally slides to the accommodating area on the clamping plate 3; 6. As Figure 10 shown, loosen the silk thread 25, push the umbilical cord clip 1 to slide upward on the clamping plate 3 until the umbilical cord clip 1 passes through the accommodating area, and pull the silk thread 25 completely through the gap between the two clamping arms; 7. As Figure 11 shown, continue to pull the valve core 5 to the end of the umbilical cord 4, and push the umbilical cord clip 1 to slide downward on the clamping plate 3 to the limit position. In this embodiment, the limit position means that the umbilical cord clip 1 contacts the valve core 5.

[0029] Embodiment 2 Based on Embodiment 1, Embodiment 2: As Figure 12 , Figure 13 shown, strip-shaped protrusions 32 are integrally formed in the length direction on the outer sides of the clamping plates 3; circumferential grooves matching the strip-shaped protrusions 32 are formed on the rotating cylinders 12.

[0030] In step one of the using method of an umbilical cord 4 ligation device, the strip-shaped protrusions 32 are aligned and cooperate with the circumferential grooves.

[0031] Embodiment 3 The difference between Embodiment 3 and Embodiment 1 is that: it further includes a linear motor. The linear motor is bolted to the upper end of the outer cylinder 21, the lower end of the output shaft of the linear motor is bolted to the upper end of the inner rod, and the inner rod is vertically slidably arranged in the outer cylinder 21.
