Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an umbilical cord hemostatic forceps. Background Technology

[0002] An umbilical cord clamp is used to clamp the newborn's umbilical cord to block blood flow. Then, the umbilical cord is cut at the point where the newborn connects to the placenta. The remaining section of the umbilical cord will detach naturally as blood flow ceases.

[0003] Chinese patent document CN214907525U discloses a new umbilical cord ligation ring. This umbilical cord ligation ring is a ring-shaped structure. During use, the umbilical cord is cut with scissors, and the end of the umbilical cord at the infant's end is positioned and clamped with hemostatic forceps. Then, dilators are used to open the umbilical cord ligation ring and place it around the base of the infant's umbilical cord.

[0004] The above procedure requires the use of tools such as hemostats, dilators, and umbilical cord ligatures. The umbilical cord must first be clamped with hemostats, and then the umbilical cord ligatures must be opened with dilators and then fitted onto the umbilical cord. These tools are kept separately, which increases the workload of medical staff and the cost of use during the umbilical cord fitting process.

[0005] Therefore, improvements are needed to address the aforementioned technical issues. Utility Model Content

[0006] The present invention aims to overcome the defects in the prior art and provide an umbilical cord hemostatic forceps with an ingenious design and simple structure that can clamp the umbilical cord of a newborn and at the same time conveniently put the umbilical cord ligation ring around it.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an umbilical cord hemostatic forceps, including a first forceps neck and a second forceps neck correspondingly arranged; the middle parts of the first forceps neck and the second forceps neck are hinged and fixed by a hinge shaft; the first forceps neck and the second forceps neck are respectively equipped with a first forceps handle and a second forceps handle; the first forceps neck and the first forceps handle are detachably connected; the second forceps neck and the second forceps handle are detachably connected; a locking device for keeping the hemostatic forceps in a locked state is arranged on the inner side of the rear end of the first forceps neck and the second forceps neck; a positioning post is fixedly provided on the top of the first forceps neck, and an umbilical cord sleeve mechanism is installed on the positioning post, the top of the positioning post and the top of the second forceps neck are on the same horizontal plane.

[0008] In a preferred embodiment of this utility model, the top of the positioning post and the top of the second clamp neck have an arc-shaped structure.

[0009] In a preferred embodiment of this utility model, the inner surfaces of the first and second jaws are provided with jaw tooth grooves, which are respectively located between the jaw tooth grooves of the first and second jaws and engage with each other; the positioning post is located at the upper end of the jaw tooth groove.

[0010] In a preferred embodiment of the present invention, the umbilical cord fitting mechanism includes an elastic ring with a clamping hole formed in the center for clamping the umbilical cord; a pull wire passes through the clamping hole.

[0011] In a preferred embodiment of this utility model, the pull wire is connected to an operating handle; the elastic ring is fitted onto the column body of the positioning column.

[0012] In a preferred embodiment of the present invention, the positioning post includes a post body and a limiting cap. The limiting cap is fixed to the top of the post body, and the bottom of the post body is fixed to the first clamp neck. Furthermore, the outer diameter of the post body is smaller than the outer diameter of the limiting cap.

[0013] In a preferred embodiment of this utility model, when the first clamp neck and the second clamp neck are in the locked state, a gap is left between the limiting cap and the inner side of the second clamp neck.

[0014] In a preferred embodiment of this utility model, the connection between the column body and the first clamp neck has an arc-shaped transition structure.

[0015] In a preferred embodiment of this invention, the length of the elastic ring is consistent with the height of the column body.

[0016] In a preferred embodiment of this invention, the outer side of the elastic ring and the outer side of the limiting cap are on the same horizontal plane.

[0017] In a preferred embodiment of this invention, the elastic ring is made of a flexible elastic material, which is rubber or medical-grade silicone.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model has a simple structure. By fixing a positioning post at the top of the first clamp neck and installing an umbilical cord sleeve mechanism on the positioning post, the elastic ring can be sleeved on the umbilical cord after the hemostatic forceps clamps the umbilical cord, which improves the operation efficiency and saves the cost of use.

[0020] 2. This utility model has an ingenious design, with the elastic ring made of medical-grade silicone. Medical-grade silicone has excellent toughness and elasticity, good processing performance, and is non-irritating, non-toxic, non-allergenic, and has very little rejection reaction to human tissue.

Detailed Implementation

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example:

[0033] like Figure 1 As shown, an umbilical cord hemostatic forceps includes a first clamp neck 1 and a second clamp neck 2 correspondingly arranged; the middle parts of the first clamp neck 1 and the second clamp neck 2 are hinged and fixed by a hinge shaft 3; the first clamp neck 1 and the second clamp neck 2 are respectively equipped with a first clamp handle 4 and a second clamp handle 5; the first clamp neck 1 and the first clamp handle 4 are detachably connected; the second clamp neck 2 and the second clamp handle 5 are detachably connected; a locking device 10 for keeping the hemostatic forceps in a locked state is arranged on the inner side of the rear end of the first clamp neck 1 and the second clamp neck 2; the first clamp neck and the first clamp handle are detachably connected; the second clamp neck and the second clamp handle are detachably connected, so that after the umbilical cord is clamped, the first clamp handle and the second clamp handle can be removed, reducing the width and length of the hemostatic forceps, making it convenient for the elastic ring 41 to be sleeved on the root of the infant's umbilical cord through the hemostatic forceps for clamping the newborn's umbilical cord.

[0034] Specifically, a positioning post 26 is fixedly provided on the top of the first clamp neck 1, and an umbilical cord sleeve mechanism 40 is installed on the positioning post 26. The present invention has a simple structure. By fixing a positioning post on the top of the first clamp neck and installing an umbilical cord sleeve mechanism on the positioning post, after the hemostat clamps the umbilical cord, the elastic ring can be sleeved on the umbilical cord through the umbilical cord sleeve mechanism, which improves the operating efficiency and saves the cost of use.

[0035] like Figure 6 As shown, the top of the positioning post 26 and the top of the second clamp neck 2 are on the same horizontal plane; the overall structure is similar to that of a hemostat, and the structure is ingeniously designed. Compared with traditional umbilical cord ligation, which requires tools such as hemostats, dilators, and umbilical cord ligation rings, the structure of this utility model is more optimized, saves costs, and reduces the operational burden on medical staff.

[0036] The top of the positioning post 26 and the top of the second clamp neck 2 are arc-shaped; the overall structure looks beautiful and avoids scratching the baby's skin by the sharp part of conventional umbilical cord hemostatic forceps, further ensuring safety in use.

[0037] The inner surfaces of the first jaw 1 and the second jaw 2 are provided with jaw tooth grooves 31, which are respectively provided between the jaw tooth grooves 31 of the first jaw 1 and the second jaw 2 and engage with each other; the positioning post 26 is located at the upper end of the jaw tooth groove 31.

[0038] like Figure 7 As shown, the umbilical cord insertion mechanism 40 includes an elastic ring 41, and a clamping hole 42 for clamping the umbilical cord is formed in the middle of the elastic ring 41; a pull wire 43 passes through the clamping hole 42.

[0039] In this invention, a pull wire 43 passes through the clamping hole 42 of the elastic ring 41. Because the elastic ring 41 is elastic, when the elastic ring 41 is fitted onto the root of the baby's umbilical cord, the pull wire 43 is pulled to make the elastic ring 41 fit onto the root of the baby's umbilical cord, which makes it convenient for doctors to cut the umbilical cord. After it is fitted, the pull wire 43 is used to cut it, which is convenient and safe.

[0040] Meanwhile, the pull cord 43 is made of cotton or plastic; in this embodiment, the pull cord 43 is made of cotton, which improves the strength of the pull cord 43 and ensures safe use.

[0041] A pull cable 43 is connected to an operating handle 44; an elastic ring 41 is fitted onto the column body 27 of the positioning column 26; wherein, the operating handle 44 consists of two detachable connecting housings, with two mounting holes formed on the housings for the pull cable 43 to pass through. The pull cable 43 is looped into the two mounting holes of the operating handle in a ring shape. After the two ends of the pull cable 43 pass through the two mounting holes, they are tied tightly in the housing, which improves the overall aesthetics and avoids the interference of the operator with the extra pull cable 43. At the same time, the operating handle 44 can be reused, saving costs.

[0042] The positioning post 26 includes a post body 27 and a limiting cap 28. The limiting cap 28 is fixed to the top of the post body 27, and the bottom of the post body 27 is fixed to the first clamp neck 1. Furthermore, the outer diameter of the post body 27 is smaller than the outer diameter of the limiting cap 28. The post body 27, the limiting cap 28, and the first clamp neck 1 are fixedly connected and integrally formed, which improves the structural strength and overall robustness of the entire hemostat, thereby ensuring safe use.

[0043] When the first clamp 1 and the second clamp 2 are in the locked state, the limiting cap 28 and the inner side of the second clamp 2 are left with a gap; this gap is to facilitate the removal of the elastic ring 41 sleeved on the column body 27.

[0044] The connection between the column body 27 and the first clamp neck 1 has an arc-shaped transition structure; this avoids the sharp points of conventional umbilical cord hemostatic forceps from scratching the baby's skin during use, further ensuring safety.

[0045] The length of the elastic ring 41 is consistent with the height of the column body 27; this allows the entire elastic ring 41 to be completely engaged between the limit cap 28 and the first clamp neck 1, avoiding the risk of the elastic ring 41 falling off the column body 27.

[0046] The outer side of the elastic ring 41 is on the same horizontal plane as the outer side of the limiting cap 28; this avoids the risk of the elastic ring 41 falling off the column body 27 and also increases the flexibility and safety of use.

[0047] The elastic ring 41 in this embodiment is made of a flexible elastic material, which is rubber or medical-grade silicone. The flexible elastic material, rubber or medical-grade silicone, has good elasticity and high plastic strength; it can directly contact infants and young children, facilitating stability and safety after umbilical cord removal.

[0048] like Figure 3 As shown, the locking device 10 consists of an upper locking tooth 11 integrally connected to the first clamp neck 1 and a lower locking tooth 12 integrally connected to the second clamp neck 2. The upper locking tooth 11 and the lower locking tooth 12 are fixedly engaged by interlocking wedge-shaped teeth. By setting the upper locking tooth and the lower locking tooth for locking and positioning, after the hemostat clamps the umbilical cord and after the first clamp handle and the second clamp handle are removed, the stability and safety of the hemostat clamping can be ensured, the weight of the hemostat itself is reduced, and the subsequent fitting of the elastic ring is facilitated.

[0049] like Figure 5 As shown, the inner surfaces of the first clamp neck 1 and the second clamp neck 2 are provided with clamp tooth grooves 31, which are respectively located between the clamp tooth grooves 31 of the first clamp neck 1 and the second clamp neck 2 and mesh with each other. In use, the upper locking tooth 11 and the lower locking tooth 12 on the locking device 10 are interlocked to fix the relative position of the first clamp neck 1 and the second clamp neck 2, so that the first clamp neck 1 and the second clamp neck 2 can stably clamp the target object. Specifically, the wedge-shaped teeth on the upper locking tooth 11 and the lower locking tooth 12 are the same as the locking toothed structure on existing hemostatic forceps and medical forceps.

[0050] The lengths of the first clamp handle 4 and the second clamp handle 5 are greater than the lengths of the first clamp neck 1 and the second clamp neck 2. This ensures stability and safety during the umbilical cord clamping process. Furthermore, after the umbilical cord is clamped, the first and second clamp handles are removed from the first and second clamp necks, reducing the overall size of the hemostat and facilitating the attachment of the elastic ring.

[0051] like Figure 4 As shown, a first insertion groove 6 is formed at the end of the first jaw 1; correspondingly, a first insertion post 7 corresponding to the first insertion groove 6 is provided on the first jaw handle 4; the first insertion post 7 is assembled in the first insertion groove 6; a second insertion groove 8 is formed at the end of the second jaw 2; correspondingly, a second insertion post 9 corresponding to the second insertion groove 8 is provided on the second jaw handle 5; the second insertion post 9 is assembled in the second insertion groove 8; by the first insertion post being assembled in the first insertion groove, the first ball bearing at the end of the first insertion post is engaged in the first positioning hole of the first insertion groove; this improves the assembly efficiency between the first jaw handle and the second jaw handle and the first jaw and the second jaw.

[0052] Specifically, the first insertion post 7 has a first mounting groove 13 with a vertical axis at its end. The first mounting groove 13 has an open end and a closed end. A first spring 14 is installed in the first mounting groove 13. A first ball bearing 15 is connected to the outer end of the first spring 14. The first ball bearing 15 extends out of the opening of the first mounting groove 13. Correspondingly, the side wall of the first insertion groove 6 has a first positioning hole 16 that matches the first ball bearing 15. The first insertion post 7 is inserted into the first insertion groove 6, and the first ball bearing 15 at the end of the first insertion post 7 is engaged in the first positioning hole 16 of the first insertion groove 6.

[0053] like Figure 2 As shown, the second insertion post 9 has a second mounting groove 20 with a vertical and horizontal axis at its end. The second mounting groove 20 has an open end and a closed end. A second spring 21 is installed in the second mounting groove 20. A second ball 22 is connected to the outer end of the second spring 21. The second ball 22 extends out of the opening of the second mounting groove 20. Correspondingly, a second positioning hole 23 is formed on the side wall of the second insertion groove 8 to match the second ball 22. The second insertion post 9 is inserted into the second insertion groove 8, and the second ball 22 at the end of the second insertion post 9 is engaged in the second positioning hole 23 of the second insertion groove 8.

[0054] During use, the first insert post is assembled into the first insert groove, and the first ball bearing at the end of the first insert post engages with the first positioning hole of the first insert groove; this improves the assembly efficiency between the first and second clamp handles and the first and second clamp necks; simultaneously, under the compression of the spring, the first ball bearing at the end of the first insert post adheres to the inner wall of the first insert groove. When the first ball bearing slides to the position of the first positioning hole of the first insert groove, it engages with the first positioning hole under the restoring force of the spring, thus securing the first clamp neck and the first clamp handle. Similarly, under the compression of the spring, the second ball bearing at the end of the second insert post adheres to the inner wall of the second insert groove. When the second ball bearing slides to the position of the second positioning hole of the second insert groove, it engages with the second positioning hole under the restoring force of the spring, thus securing the second clamp neck and the second clamp handle; this improves ease of use.

[0055] During use, after the hemostat has clamped the umbilical cord, when it is necessary to separate the first clamp handle 4 and the second clamp handle 5 from the first clamp neck 1 and the second clamp neck 2, simply press the first and second ball bearings. Driven by the first and second clamp handles, the first and second ball bearings move outward along the first and second insertion slots under the compression of the springs, until the first clamp handle 4 separates from the first clamp neck 1 and the second clamp handle 5 separates from the second clamp neck 2. Then, pull the cable 43 to extend the clamping hole 42. The elastic ring 41 is opened by the opening mechanism. After opening, the elastic ring 41 is passed over the hemostat used to remove the first clamp handle 4 and the second clamp handle 5, and then fitted onto the infant's umbilical cord. The pull line 43 is pulled to adjust the elastic ring 41 so that it fits snugly against the base of the infant's umbilical cord. After the fitting is completed, the pull line 43 is released so that the clamping hole 42 of the elastic ring 41 can be used to clamp the umbilical cord. This prevents the infant from being infected with bacteria during growth. After the elastic ring 41 has completed the entire fitting process, it is convenient for the doctor to cut the umbilical cord, which is convenient and safe.

[0056] The end of the first insertion slot 6 near the first ball bearing 15 has a right arc structure 17; the end of the second insertion slot 8 near the second ball bearing 22 has a left arc structure 18. By setting the right arc structure and the left arc structure, this utility model facilitates the engagement of the first clamp neck and the first clamp handle or the second clamp neck and the second clamp handle, increases the contact area between the first ball bearing and the second ball bearing and the right arc structure and the left arc structure, and improves the safety and stability of assembly.

[0057] The outer sides of the ends of the first insertion slot 6 and the second insertion slot 8 are both inclined arc portions 19; after the umbilical cord is clamped and the first and second clamps are disassembled, in the process of fitting the elastic ring, the ends of the first insertion slot and the second insertion slot should not touch the elastic ring, thereby causing damage to the elastic ring. The inclined arc portion can increase the contact area between the inclined arc portion and the elastic ring, ensuring the safety of fitting the elastic ring.

[0058] The end of the first clamp handle 4 is located on the first clamp handle 24 for easy gripping, and the first clamp handle 24 and the first clamp handle 4 are integrally formed; the end of the second clamp handle 5 is located on the second clamp handle 25 for easy gripping, and the second clamp handle 25 and the second clamp handle 5 are integrally formed; wherein, the first clamp handle 24 and the second clamp handle 25 are both circular structures; which facilitates the doctor's operation.
