Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to an umbilical cord clamp and its usage method. Background Technology
[0002] In the clinical management of newborns after delivery, the umbilical cord clipper is an indispensable medical device. Its core function is to integrate clamping and cutting of the umbilical cord to improve efficiency and reduce the risk of neonatal blood loss. Existing integrated umbilical cord clippers simplify the procedure by combining clamping and cutting functions. However, the clamping and cutting actions of these products are usually coupled within the same continuous gripping force process, lacking an effective mechanism to confirm the reliability of the clamping. Furthermore, once the operation is initiated, it is irreversible. Operators must rely on their own experience to judge whether the clamping is in place, which can easily lead to insufficient clamping force or misjudgment, resulting in premature cutting and subsequent umbilical cord bleeding, posing a threat to the clinical safety of the newborn.
[0003] Neonatal umbilical cord care demands extremely high levels of operational safety and reliability. Existing umbilical cord clippers, due to structural design flaws, cannot fundamentally ensure that the clamping action precedes the cutting action, nor can they provide clear feedback on clamping completion to the operator. This increases operational uncertainty and makes it difficult to completely eliminate the risk of cutting before clamping. To address this critical technical issue, there is an urgent need for an umbilical cord clipper that, through structural design, forces reliable clamping before cutting and provides clear feedback on clamping completion, thereby improving operational safety and reliability and ensuring safe clinical use in newborns. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an umbilical cord clamping device and its usage method, solving the problems that existing clamping devices cannot structurally guarantee that clamping precedes cutting, and lack clear feedback on clamping completion, thus posing a risk of cutting before clamping.

The overall moving parts are streamlined, the operation is stable, the probability of failure is reduced, and the convenience of use, the durability of the instrument, and the optimization of the clinical operation experience are all taken into account, comprehensively improving the practical value and clinical applicability of the instrument.

[0010] Preferably, a second spring is provided inside the limiting cylinder, one end of the second spring is fixedly connected to the outer wall of the limiting ring, and the other end abuts against the inner wall of the limiting cylinder, and the outer wall of the locking block is slidably connected to the inner wall of the docking groove.
[0011] Preferably, after the docking block is fully slid into the docking groove, the top of the locking block contacts the bottom of the locking rod and makes a sound to indicate to the operator that the clamping of the first and second clamps has been completed.

[0013] Preferably, the first connecting shaft has a slot inside, the outer wall of the card block is slidably connected to the inside of the slot, and the scissors are connected to the first handle and the second handle through the second connecting shaft and the first connecting shaft.
[0014] Preferably, a method of using an umbilical cord clamp, for use with the aforementioned umbilical cord clamp, includes the following steps: S1. Placement and initial closure: Place the umbilical cord between the open first and second clamps, and the operator begins to grip the first and second handles, thereby driving the first and second clamps to close. S2. Forced clamping and locking: When the first and second clamps are gripped and closed, the first and second clamps will contact the umbilical cord and apply pressure. During the closing process of the first and second clamps, the docking block will slide into the docking groove.

[0017] This invention provides an umbilical cord clamp and its method of use. It has the following beneficial effects: 1. In this invention, the sliding engagement of the docking block of the first clamp body with the docking groove of the second clamp body, combined with the locking structure of the docking assembly and the clamping rod, and the limiting effect of the partition ring and the first spring, structurally forces the clamping and locking action to precede the shearing action, eliminating the risk of cutting before clamping.

At the same time, different specifications of scissors can be flexibly replaced according to the thickness of the umbilical cord to adapt to diverse usage needs, improve the versatility of the instrument, and only the worn or damaged scissors need to be replaced, without replacing the entire instrument, thus reducing the cost of use.
[0019] 3. In this invention, the elastic plate design on the outer wall of the scissors allows the scissors to automatically spring back and open after cutting, eliminating the need for manual reset and simplifying the operation. Combined with the cooperative structure of the limiting cylinder, the second spring, and the limiting ring, unlocking only requires pressing the lever to push the locking block to retract, quickly releasing the clamp body lock. The overall structure achieves stable operation through the synergistic action of the spring and locking components. The simplified moving parts reduce the probability of malfunctions, improve ease of use and instrument durability, and optimize the clinical operating experience. Attached Figure Description

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Please see the appendix Figure 1 -Appendix Figure 8This invention provides an umbilical cord clamping device, including a first handle 1, a first clamp body 2, a second handle 5, a second clamp body 6, a connecting component 7, and scissors 13. A docking block 3 is fixedly connected to the outer wall of the first clamp body 2, and a docking component 4 is provided inside the docking block 3. A docking groove 8 and a limiting groove 12 are provided inside the second clamp body 6. A locking rod 9 is slidably connected to the inner wall of the second clamp body 6. A partition ring 10 and a first spring 11 are provided inside the limiting groove 12. When the first clamp body 2 and the second clamp body 6 are closed, the outer wall of the docking block 3 is slidably connected to the inner wall of the docking groove 8. An elastic piece 14 is provided on the outer wall of the scissors 13.
[0024] Specifically, the connecting component 7 serves to stably connect the first handle 1, the second handle 5, and the scissors 13. It provides a reliable fulcrum for the rotation of the first handle 1 around the second handle 5 and enables the first clamping body 2 and the second clamping body 6 to precisely align, thus achieving a smooth clamping of the umbilical cord. The first clamping body 2 provides stable support for the docking block 3, allowing the docking block 3 to drive the docking component 4 to precisely embed into the docking groove 8, providing a structural basis for subsequent clamping and locking. The docking component 4, driven by the docking block 3, drives the locking rod 9, causing it to slide stably inside the second clamping body 6. Simultaneously, the locking rod 9 drives the spacer ring 10 to move synchronously within the limiting groove 12. The spacer ring 10 serves to limit the movement of the first clamping body 13. The function of spring 11 is to prevent the first spring 11 from shifting or dislodging during deformation, and to accurately transmit the force of the clamping rod 9, limiting the sliding stroke of the clamping rod 9. This, in turn, compresses the first spring 11 to produce uniform elastic deformation. The rebound force of the first spring 11, in conjunction with the engagement of the docking component 4 and the clamping rod 9, ensures that the first clamping body 2 and the second clamping body 6 are firmly locked after closing, effectively preventing accidental opening during use. The second clamping body 6 provides precise sliding support and limiting guidance for the clamping rod 9, and the limiting groove 12 provides a suitable installation space and stable sliding trajectory for the partition ring 10 and the first spring 11, thereby ensuring the overall stability and reliability of the clamping and locking structure and preventing clamping failure due to component shift.
[0025] Please see the appendix Figure 1 -Appendix Figure 8 The outer wall of the first clamp body 2 is fixedly connected to the outer wall of the first handle 1, the outer wall of the second clamp body 6 is fixedly connected to the outer wall of the second handle 5, the second handle 5 and the second clamp body 6 are connected by a connecting component 7, and the scissors 13 are connected to the second handle 5 and the first handle 1 by the connecting component 7; the inner wall of the partition ring 10 is fixedly connected to the outer wall of the clamping rod 9, the outer wall of the partition ring 10 is slidably connected to the inner wall of the limiting groove 12, the outer wall of the first spring 11 is set on the outer wall of the clamping rod 9, one end of the first spring 11 abuts against the outer wall of the partition ring 10, and the other end abuts against the inner wall of the limiting groove 12.
[0026] Specifically, the first handle 1 provides stable support for the first clamp body 2, allowing the first clamp body 2 to move synchronously and precisely with the rotation of the first handle 1, thereby ensuring efficient transmission of force during clamping. The second handle 5 provides stable support for the second clamp body 6, providing a solid mounting base for the second clamp body 6, thus ensuring the structural stability of the instrument throughout the clamping and cutting process and preventing deformation under stress. The sliding cooperation of the first connecting shaft 701 and the second connecting shaft 703 of the connecting assembly 7 not only stably connects the first handle 1 and the second handle 5, but also provides a smooth and unobstructed fulcrum for their relative rotation. At the same time, it can evenly transmit the operating force of the first handle 1 to the first clamp body 2, achieving precise alignment and clamping with the second clamp body 6, ensuring balanced force during umbilical cord clamping, and avoiding excessive local pressure that could damage the umbilical cord or insufficient pressure that could lead to insecure clamping.
[0027] Please see the appendix Figure 1 -Appendix Figure 6 The docking assembly 4 includes a limiting cylinder 401, the outer wall of which is fixedly connected to the inside of the docking block 3. A locking block 402 is slidably connected to the inner wall of the limiting cylinder 401. A limiting ring 403 is fixedly connected to the bottom end of the locking block 402. The outer wall of the limiting ring 403 is slidably connected to the inner wall of the limiting cylinder 401. A second spring 404 is provided inside the limiting cylinder 401. One end of the second spring 404 is fixedly connected to the outer wall of the limiting ring 403, and the other end abuts against the inner wall of the limiting cylinder 401. The outer wall of the locking block 402 is slidably connected to the inner wall of the docking groove 8. After the docking block 3 is fully slid into the docking groove 8, the top end of the locking block 402 contacts the bottom end of the locking rod 9 and makes a sound to indicate to the operator that the clamping of the first clamp 2 and the second clamp 6 has been completed.
[0028] Specifically, after the first clamp 2 drives the docking block 3 and docking component 4 to fully enter the docking groove 8, the top of the locking block 402 of the docking component 4 makes precise contact with the bottom of the locking rod 9, producing a clicking locking sound. This provides the operator with clear auditory and tactile feedback, clearly indicating that the first clamp 2 and the second clamp 6 have clamped in place and are reliably locked. This allows the operator to confidently perform subsequent cutting operations, completely avoiding the risk of cutting before clamping from the operational feedback perspective. After clamping and locking are completed, by gripping the handle of the scissors 13, the operator can use the sharp edge of the scissors 13 to... The sharp blade generates concentrated shearing force, acting on the firmly clamped umbilical cord, thus achieving a reliable clamping followed by cutting, ensuring the safety of umbilical cord treatment and reducing the risk of bleeding. The elastic plate 14 on the outer wall of the scissors 13 provides automatic return force, eliminating the need for manual operation after cutting. The elastic plate 14 automatically opens the blade of the scissors 13, facilitating future use, reducing operator steps, improving work efficiency, and preventing blade wear or accidental damage caused by prolonged closure. External scratches; After use, by pressing the lever 9, the partition ring 10 slides smoothly in the limiting groove 12 of the second clamp body 6 and squeezes the first spring 11 to retract. At the same time, the lever 9 precisely pushes the locking block 402, causing the locking block 402 to drive the limiting ring 403 to slide at a constant speed in the limiting cylinder 401 and squeeze the second spring 404 to retract. When the locking block 402 slides completely into the limiting cylinder 401, the locking state between the first clamp body 2 and the second clamp body 6 is released, and the instrument can be opened easily and smoothly; the diameter of the part of the lever 9 that contacts the locking block 402 is slightly larger. The diameter of the locking block 402 effectively restricts the movement trajectory of the locking rod 9, preventing it from sliding into the limiting cylinder 401 and causing the component to jam, thus ensuring the precision and controllability of the unlocking action. Through the symmetrical distribution of the docking components 4 and the locking rods 9, the two locking rods 9 stably clamp a set of docking components 4 in the middle, which plays a role in evenly transmitting the force, thereby ensuring that the force is uniform when the first clamp body 2 and the second clamp body 6 are clamped, improving the reliability and stability of the clamping, and avoiding excessive local force that could cause umbilical cord tissue damage or loose clamping leading to bleeding.
[0029] Please see the appendix Figure 7 and attached Figure 8The connecting component 7 includes a first connecting shaft 701 and a second connecting shaft 703. The outer wall of the second connecting shaft 703 is slidably connected to the inner wall of the first connecting shaft 701. A docking component 4 is disposed inside the second connecting shaft 703. The second connecting shaft 703 is connected to the first connecting shaft 701 through the docking component 4. The first connecting shaft 701 is disposed between the first handle 1 and the second handle 5 for connecting the first handle 1 and the second handle 5. The outer wall of the second connecting shaft 703 is disposed inside the scissors 13. A slot 702 is provided inside the first connecting shaft 701. The outer wall of the locking block 402 is slidably connected inside the slot 702. The scissors 13 is connected to the first handle 1 and the second handle 5 through the second connecting shaft 703 and the first connecting shaft 701.
[0030] Specifically, the first connecting shaft 701 connects the first handle 1 and the second handle 5, providing stable and robust support for their relative rotation, thus ensuring smooth operation and efficient force transmission. The second connecting shaft 703 is fixedly connected to the scissors 13, providing a precise mounting carrier and flexible rotation fulcrum for the scissors 13, allowing them to open and close flexibly during operation and ensuring the accuracy of the cutting action. The locking block 402 of the docking component 4 precisely engages with the slot 702 of the first connecting shaft 701, securing the second connecting shaft 703 firmly to the first connecting shaft 701, thus ensuring reliable connection between the scissors 13 and the first handle 1 and the second handle 5, preventing the scissors 13 from loosening or shifting during cutting. With this detachable design, installing the scissors 13 simply requires aligning the second connecting shaft 703 with the first connecting shaft 701 and inserting it. At this time, the inner wall of the first connecting shaft 701 presses against the locking block 402, causing the locking block 402 to compress the second spring 404. When the locking block 402 slides to the position of the locking slot 702, the second spring 404 quickly rebounds and pushes the locking block 402 to firmly abut against the locking slot 702, thus quickly and securely completing the installation of the scissors 13. The operation is simple and requires no additional tools. When disassembling, simply pull the scissors 13 directly. The locking block 402 is squeezed and retracted by the edge of the locking slot 702, which allows the second connecting shaft 703 to be smoothly pulled out from the first connecting shaft 701, realizing the quick disassembly of the scissors 13. This detachable design not only facilitates the replacement of scissors 13 of different specifications to meet the needs of umbilical cord treatment for newborns of different thicknesses, but also facilitates the deep cleaning and high-temperature sterilization of the scissors 13 separately, reducing the risk of cross-infection in clinical settings. At the same time, the scissors 13 can be replaced separately when the blade is worn or damaged, without replacing the entire instrument, significantly reducing the overall replacement cost of the instrument. In addition, the disassembled parts are smaller in size and more regular in shape, making them easier to classify, store, carry and transport, greatly improving the overall flexibility, practicality and economy of use.
[0031] Please see the appendix Figure 1 -Appendix Figure 8A method for using an umbilical cord clamp, for use with the aforementioned umbilical cord clamp, includes the following steps: S1. Placement and initial closure: Place the umbilical cord between the open first clamp 2 and the second clamp 6. The operator begins to grip the first handle 1 and the second handle 5, thereby driving the first clamp 2 and the second clamp 6 to close. S2, Forced clamping and locking: When the first clamp 2 and the second clamp 6 are gripped and closed, the first clamp 2 and the second clamp 6 will contact the umbilical cord and apply pressure. During the closing process of the first clamp 2 and the second clamp 6, the docking block 3 will slide into the docking groove 8. When the clamping force reaches the preset value, the locking block 402 will slide into the docking groove 8 and contact the locking rod 9, at which time a sound will be made. S3. Cutting: After the first clamp 2 and the second clamp 6 close and clamp the umbilical cord, the handle of the scissors 13 is then gripped tightly. Under the cutting force of the scissors 13, the clamped umbilical cord can be cut.
[0032] In step S2, the sound is used to indicate to the operator that the clamping has been reliably completed.
[0033] Specifically, in actual use, the first handle 1 and the second handle 5 are initially in a naturally open state. The scissors 13 maintain their open blades under the elastic support of the elastic plate 14. The locking block 402 of the docking component 4 extends partially out of the limiting cylinder 401 under the rebound force of the second spring 404. The locking rod 9 is limited in the limiting groove 12 by the partition ring 10 under the support of the first spring 11, ensuring that all components are in a stable state ready for operation. The operator first places the newborn's umbilical cord in the clamping area between the first clamp body 2 and the second clamp body 6. Then, the operator holds the first handle 1 and the second handle 5 with both hands and slowly applies gripping force. Under the transmission cooperation of the first connecting shaft 701 and the second connecting shaft 703 of the connecting component 7, the first handle 1 drives the first clamp body 2 to rotate towards the second clamp body 6. The second handle 5 provides stable support for the second clamp body 6, making the two precisely aligned. As the gripping force is continuously applied, the docking block 3 on the first clamp body 2 gradually slides into the docking groove 8 of the second clamp body 6. When the docking block 3 is fully embedded in the docking groove 8, the top of the locking block 402 of the docking component 4 makes precise contact with the bottom of the locking rod 9 and produces a clicking locking sound, providing the operator with clear auditory and tactile feedback, indicating that the umbilical cord has been reliably clamped. At this time, the locking block 402 and the locking rod 9 are engaged with each other, and together with the limiting effect of the partition ring 10 on the first spring 11, the first clamp body 2 and the second clamp body 6 are firmly locked, effectively preventing accidental loosening during the clamping process.
[0034] After clamping and locking, the operator continues to apply gripping force. At this point, the first clamp 2 and the second clamp 6 can no longer close further. The force is transmitted to the scissors 13 through the connecting component 7, causing the blades of the scissors 13 to move closer together and precisely cut the locked umbilical cord. During the cutting process, the second connecting shaft 703 acts as the rotation fulcrum of the scissors 13, ensuring that the cutting force is concentrated and stable, preventing the umbilical cord from slipping or being cut incompletely. After cutting, the elastic plate 14 immediately releases its elastic potential energy, causing the blades of the scissors 13 to automatically spring back and open. This eliminates the need for manual resetting by the operator, simplifying the operation and preventing wear or accidental scratches caused by prolonged blade closure. After the entire umbilical cord treatment process is completed, the operator presses the levers 9 on both sides of the second clamp body 6. The levers 9 drive the partition ring 10 to slide in the limiting groove 12 and squeeze the first spring 11 to retract. At the same time, the levers 9 push the locking block 402 to slide into the limiting cylinder 401. The locking block 402 drives the limiting ring 403 to squeeze the second spring 404 to retract until the locking block 402 is completely retracted into the limiting cylinder 401. The locking state of the first clamp body 2 and the second clamp body 6 is released. At this time, the first handle 1 and the second handle 5 can be released to easily open them and take out the treated umbilical cord.
[0035] If it is necessary to replace the scissors 13 with different specifications or to clean and disinfect them, the scissors 13 can be pulled directly. The edge of the slot 702 exerts a squeezing force on the locking block 402, causing the locking block 402 to retract and disengage from the slot 702. This allows the second connecting shaft 703 to be pulled out from the first connecting shaft 701, completing the quick disassembly of the scissors 13. During installation, simply align the second connecting shaft 703 with the interface of the first connecting shaft 701 and insert it. The inner wall of the first connecting shaft 701 squeezes the locking block 402 to retract. When the locking block 402 slides to the position of the slot 702, the second spring 404 rebounds and pushes the locking block 402 into the slot 702, thus achieving a stable installation of the scissors 13. The entire process requires no additional tools, making it convenient and efficient. At the same time, by disassembling the scissors 13 separately, deep cleaning and disinfection can be performed, reducing the risk of cross-infection in clinical settings. It also allows for flexible replacement of the appropriate scissors 13 according to the thickness of the umbilical cord, improving the versatility and practicality of the instrument. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

7. The umbilical cord clamp according to claim 1, characterized in that, The connecting component (7) includes a first connecting shaft (701) and a second connecting shaft (703). The outer wall of the second connecting shaft (703) is slidably connected to the inner wall of the first connecting shaft (701). The docking component (4) is disposed inside the second connecting shaft (703). The second connecting shaft (703) is connected to the first connecting shaft (701) through the docking component (4). The first connecting shaft (701) is disposed between the first handle (1) and the second handle (5) for connecting the first handle (1) and the second handle (5). The outer wall of the second connecting shaft (703) is disposed inside the scissors (13).
8. The umbilical cord clamp according to claim 7, characterized in that, The first connecting shaft (701) has a slot (702) inside, and the outer wall of the card block (402) is slidably connected to the inside of the slot (702). The scissors (13) are connected to the first handle (1) and the second handle (5) through the second connecting shaft (703) and the first connecting shaft (701).
9. A method of using an umbilical cord clamp, characterized in that, An umbilical cord clamp as described in any one of claims 1-8 includes the following steps: S1. Placement and initial closure: Place the umbilical cord between the open first clamp (2) and second clamp (6), and the operator begins to grip the first handle (1) and the second handle (5), thereby driving the first clamp (2) and the second clamp (6) to close. S2, Forced clamping and locking: When the first clamp (2) and the second clamp (6) are gripped and closed, the first clamp (2) and the second clamp (6) will contact the umbilical cord and apply pressure. During the closing process of the first clamp (2) and the second clamp (6), the docking block (3) will slide into the docking groove (8). When the clamping force reaches the preset value, the locking block (402) will slide into the docking groove (8) and contact the locking rod (9), at which time a sound will be made. S3, Cutting: After the first clamp (2) and the second clamp (6) close and clamp the umbilical cord, the handle of the scissors (13) is then gripped tightly, and the clamped umbilical cord can be cut off under the shearing force of the scissors (13).
10. The method of using the umbilical cord clipper according to claim 9, characterized in that: In step S2, the sound is used to indicate to the operator that the clamping has been reliably completed.
