Description

Technical Field

[0001] The utility model relates to the field of scalp hemostasis, in particular to an adjustable hinge-type trauma hemostasis clamp. Background Art

[0002] Due to the unique anatomy and tissue structure of the scalp, using hemostatic clamps to stop bleeding during surgery is difficult. Scalp hemostatic clamps can quickly clamp the edges of scalp wounds to achieve rapid and effective hemostasis. However, during first aid at combat (trauma) sites, traditional sutures and ligations are difficult to implement temporarily to treat the rapid and severe bleeding caused by scalp trauma. Currently, the most commonly used first aid method is pressure bandaging. While effective, it cannot specifically clamp the edges of scalp wounds to stop bleeding, and bleeding can often remain uncontrolled even after bandaging. This results in poor hemostasis and, in severe cases, can even cause hemorrhagic shock, endangering the casualty's life.

[0003] The plastic scalp hemostatic clamps used in surgical operations have problems such as weak holding force, easy to fall off, unable to stretch the wound edge and close the wound surface, and the need for matching scalp clamps. At present, the relevant invention patents are also small scalp hemostatic clamps similar to those used in surgical operations. The size of the thin sheet opening and the holding force for clamping the wound edge cannot be adjusted, and the clamping force is limited. Therefore, the first aid for scalp traumatic bleeding at the scene of war (wounds) has the disadvantages of a single treatment method and poor treatment effect. For example, the invention patent named a hemostatic clamp can achieve the clamping and loosening of the elastic clamp by moving the elastic clamp axially (application number is CN202111660284.3), and achieve compression and hemostasis of the blood vessels on one side of the wound, but it is easy to fall off, and the overall hemostatic effect is poor.

[0004] To achieve rapid and precise scalp hemostasis at the scene of combat trauma, there is an urgent need to develop a compact, portable, simple-to-use, and effective scalp hemostatic clamp capable of wound closure. This clamp demonstrates unique advantages in scalp hemostasis. Furthermore, it can also be used to stop bleeding and close wounds in other areas of severe soft tissue trauma.

[0005] Based on the above, the present invention discloses an adjustable hinged scalp wound hemostatic clamp, which achieves: (1) temporary closure of the wound by stretching to reduce the risk of infection, and (2) fixing the hemostatic clamp body on the scalp by limiting needles and continuously clamping the scalp wound edges on both sides to stop bleeding; (3) the tightness of the hemostatic clamp can be adjusted according to needs. Utility Model Content

[0006] The utility model aims to provide an adjustable hinged wound hemostatic clamp, aiming to improve the problems that conventional hemostatic clamps are prone to falling off, cannot close the wound by stretching the wound edge, and have poor overall hemostatic effect.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An adjustable hinged trauma hemostatic clamp comprises a first clamp body, a second clamp body and a locking mechanism, wherein the bottoms of opposite sides of the first clamp body and the second clamp body are both provided with a plurality of interleaved engaging pins;

[0009] At least one limiting cylinder is provided on the side of the first clamp body facing the second clamp body, and the locking mechanism is provided in the limiting cylinder.

[0010] The locking mechanism includes a driving handle and at least one set of rotation limiting components, the rotation limiting components including a rotating block and a fixed block, the rotating block is rotatably arranged in the limiting cylinder via a rotating shaft, the fixed block is fixed in the limiting cylinder, the rotating block and the fixed block are respectively provided with a rotating channel and a limiting channel that are interconnected, and the driving handle is inserted into the rotating channel and the limiting channel;

[0011] A driving member is fixed in the rotating channel and is drivingly connected to the driving handle. A plurality of limiting members are fixed in the limiting channel. At least one engaging member is provided on the circumference of the driving handle, and the engaging member is embedded between the limiting members.

[0012] The top of the second clamp body passes through the limiting cylinder and is fixedly connected to the rotating block.

[0013] Furthermore, the driving member includes a driving gear, which is sleeved on the circumference of the driving handle. A plurality of driving teeth protruding outward are fixed on the inner side wall of the rotating channel, and the driving teeth are engaged with the driving gear.

[0014] Furthermore, the limiting member includes a first limiting arm, and the engaging member includes a second limiting arm. The first limiting arms are fixed on the inner wall of the limiting channel at intervals, and the second limiting arms are fixed on the peripheral side of the driving handle. An embedding space for the second limiting arm is formed between adjacent first limiting arms.

[0015] Furthermore, the length difference between the rotating channel and the driving gear is greater than or equal to the length of the limiting channel.

[0016] Furthermore, the diameter of the rotating channel is larger than the diameter of the limiting channel, one side of the rotating block and the fixed block are pressed against each other, and a plane bearing is fixed between the opposite sides of the rotating block and the fixed block.

[0017] Furthermore, there are two limiting cylinders, which are spaced apart at both ends of one side of the first clamp body. There are two groups of rotation limiting assemblies, which are respectively arranged in the two limiting cylinders.

[0018] The driving handle is inserted into the two limiting cylinders and protrudes from the limiting cylinders.

[0019] Furthermore, one end of the driving handle is provided with a protrusion extending outward, and the protrusion is located outside the limiting cylinder.

[0020] Furthermore, the engaging pins on the first clamp body and the engaging pins on the second clamp body are arranged alternately.

[0021] Furthermore, the engaging needle is a straight needle, and the bottom ends of the engaging needles of the first clamp body and the second clamp body are inclined toward each other.

[0022] Furthermore, the engaging needle is a curved needle, and the needle tips of the engaging needles of the first clamp body and the second clamp body are bent toward each other.

[0023] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0024] The first clamp body and the second clamp body occlude the wound edges on both sides of the wound surface through the occlusal needle, clamping one side of the wound edge to stop bleeding;

[0025] During the clamping process, the driving handle drives the rotating block to rotate, thereby driving the second clamp body to move toward the first clamp body, stretching the wound edges on both sides, driving the wound surface to close, increasing pressure and improving the hemostasis effect; when the wound edges on both sides are in alignment, the first clamp body and the second clamp body clamp the wound edges on both sides to complete the hemostasis.

[0026] During the loosening process, the drive handle rotates the rotating block, thereby moving the second clamp body away from the first clamp body, loosening the stretched wound edges and opening and loosening the wound surface. The limiting member only limits the lateral direction of the drive handle. By driving the drive handle forward or backward, the limiting member and the engaging member engage or disengage, applying or releasing the restraining force on the drive handle. The limiting member and engaging member provide a continuous retaining force between the first and second clamp bodies, ensuring a tight fit between the bottom ends of the first and second clamp bodies and the edges of the scalp wound. This increases the force of the clamped scalp wound edges, pulling the wound inward and closing it, achieving better hemostasis. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Example

[0048] Please refer to Figure 1-8As shown, this embodiment provides an adjustable hinged trauma hemostatic clamp, comprising a first clamp body 1, a second clamp body 2, and a locking mechanism 3. A plurality of interlocking pins 4 are provided at the bottom of opposing sides of the first clamp body 1 and the second clamp body 2. At least one limiting cylinder 11 is provided on the side of the first clamp body 1 facing the second clamp body 2, and the locking mechanism 3 is disposed within the limiting cylinder 11. Specifically, the locking mechanism 3 includes a driving handle 31 and at least one set of rotation limiting assemblies. The rotation limiting assembly includes a rotating block 321 and a fixed block 322. The rotating block 321 is rotatably disposed within the limiting cylinder 11 via a rotating shaft 6, and the fixed block 322 is fixed within the limiting cylinder 11. The rotating block 321 and the fixed block 322 are respectively defined with a rotating channel 3211 and a limiting channel 3221 that are interconnected. The driving handle 31 is disposed within the rotating channel 3211 and the limiting channel 3221. A driving member is fixed within the rotation channel 3211 and is drivingly connected to the driving handle 31. Multiple limiting members are fixed within the limiting channel 3221. At least one engaging member is disposed around the periphery of the driving handle 31. The engaging member is embedded between the limiting members, and the limiting members limit the engaging member, thereby limiting the periphery of the driving handle 31. The top of the second clamp body 2 passes through the limiting cylinder 11 and is fixedly connected to the rotating block 321. In this embodiment, the rotation limiting assembly further includes a housing 323, which is fixed within the limiting cylinder 11. A fixed block 322 and a rotating block 321 are disposed within the housing 323. The fixed block 322 is fixedly connected to the inner side of the housing 323, and the rotating block 321 is rotatably connected to the inner side of the housing 323 via a rotating shaft 6. Both the housing 323 and the limiting cylinder 11 define a channel 3231 for the second clamp body 2 to pass through. The top of the second clamp body 2 passes through the limiting cylinder 11 and the housing 323 and is fixedly connected to the rotating block 321. The housing 323 protects the rotating block 321 and the fixed block 322 to prevent debris from affecting the rotation and limiting function of the fixed block 322 and the rotating block 321 .

[0049] The first clamp body 1 and the second clamp body 2 engage the edges of the scalp wound surface via the engaging needle 4. During the clamping and loosening processes, the driving handle 31 drives the rotating block 321 to rotate, thereby driving the second clamp body 2 toward or away from the first clamp body 1, causing the scalp wound surface to adhere, increasing pressure to enhance hemostasis, or loosening the wound edge. In the clamped state or when hemostasis is complete, the limiting member only limits the lateral direction of the driving handle 31. By driving the driving handle 31 forward or backward, the limiting member and the engaging member engage or disengage with each other, thereby applying or releasing the limiting force on the driving handle 31. The limiting member and the engaging member provide continuous holding force for the first and second clamp bodies 1 and 2, ensuring a tight fit between the bottom ends of the first and second clamp bodies 1 and 2 and the scalp wound edge, increasing the force of clamping the skin wound edge and achieving a better hemostasis effect.

[0050] Please refer to Figure 3-8As shown, specifically, the driving member includes a driving gear 312, which is sleeved around the circumference of the driving handle 31. A plurality of outwardly protruding driving teeth 3212 are fixed to the inner sidewall of the rotating channel 3211, and the driving teeth 3212 mesh with the driving gear 312. The driving handle 31 drives the driving gear 312 to rotate, thereby rotating the driving teeth 3212 and the rotating block 321, and the second clamp body rotates, thereby achieving the purpose of tightening or loosening the hemostatic clamp. Furthermore, during the transition from the tightening process to the pressure-holding process, or from the pressure-holding process to the loosening process, the driving teeth 3212 only limit the driving gear 312 in the circumferential direction. In the axial direction of the driving handle 31, the driving teeth 3212 serve as a guide during the forward or backward movement of the driving handle 31, ensuring the accuracy of the movement of the driving handle 31.

[0051] Specifically, the limiting member includes a first limiting arm 3222, and the engaging member includes a second limiting arm 311. The first limiting arms 3222 are fixed to the inner sidewall of the limiting channel 3221 at intervals, and the second limiting arms 311 are fixed to the circumference of the driving handle 31. Adjacent first limiting arms 3222 form an embedding space for the second limiting arms 311. During the pressure-maintaining process, the second limiting arms 311 are embedded between adjacent first limiting arms 3222. The adjacent first limiting arms 3222 on both sides of the second limiting arms 311 provide a limiting force in the circumferential direction of the second limiting arms 311, restricting the driving handle 31 from rotating in the circumferential direction, thereby achieving the purpose of pressure maintenance and providing continuous pressing force on both sides of the wound.

[0052] In this embodiment, the free end of the first limiting arm 3222 is bent to one side, and the bending directions of the multiple first limiting arms 3222 are the same; the free end of the second limiting arm 311 is bent to one side, and the bending directions of the multiple second limiting arms 311 are the same, that is, the bending directions of the first limiting arm 3222 and the second limiting arm 311 are opposite. During the pressure-holding process, the second limiting arm 311 is embedded between the adjacent first limiting arms 3222, and the free end of the second limiting arm 311 is pressed against the bottom end of the first limiting arm 3222, and the free end of the first limiting arm 3222 is pressed against the bottom end of the second limiting arm 311, forming a reverse gripping and pressing structure, which plays a good limiting role in the circumferential direction of the driving handle 31, and a bending structure is provided at the free ends of the first limiting arm 3222 and the second limiting arm 311 to reduce the structural strength of the first limiting arm 3222 and the second limiting arm 311, and provide a certain resilience for the scalp trauma hemostatic clamp during the pressure-holding process to avoid excessive pressing force on the wound. In this embodiment, there are six limiters and three engaging members. The six limiters provide six spaces for the engaging members, limiting the engaging members in multiple directions to meet pressure-holding requirements of varying forces. The three engaging members limit the driving handle 31 in multiple directions, ensuring good stability during the pressure-holding process. Similarly, other numbers of limiters and engaging members can be provided to achieve different engagement requirements.

[0053] Please refer to Figure 9 As shown, similarly, the first limiting arm 3222 and the second limiting arm 311 can also be prism-shaped protrusions extending outward, and the driving handle 31 is limited by the abutting contact between the two side surfaces of the first limiting arm 3222 and the second limiting arm 311. The contact between the inclined surfaces effectively increases the contact area between the lower limiting arm and the second limiting arm 311, thereby increasing the magnitude of the limiting force applied by the first limiting arm 3222 to the driving handle 31 through the second limiting arm 311, thereby improving the limiting effect.

[0054] Please refer to Figure 3-8As shown, specifically, the length difference between the rotating channel 3211 and the driving gear 312 is greater than or equal to the length of the limiting channel 3221. In this embodiment, the length difference between the rotating channel 3211 and the driving gear 312 is equal to the length of the limiting channel 3221. Similarly, the length difference between the rotating channel 3211 and the driving gear 312 can also be greater than the length of the limiting channel 3221. The driving gear 312 moves back and forth in the length direction of the driving channel 3231. The length difference between the rotating channel 3211 and the driving gear 312 is the length space for the driving gear 312 to move back and forth. The length difference between the rotating channel 3211 and the driving gear 312 is greater than or equal to the length of the limiting channel 3221. This ensures that the engaging element can fully enter the limiting channel 3221 during the transition from the tightening process to the pressure holding process, ensuring that the scalp trauma hemostatic clip has good tensioning and pressure application effects. Alternatively, the engaging element can completely disengage from the limiting channel 3221 during the transition from the pressure holding process to the release process, ensuring a stable release process.

[0055] Furthermore, the diameter of the rotating channel 3211 is larger than the diameter of the limiting channel 3221, and one side of the rotating block 321 and the fixed block 322 abut against each other. Specifically, the fixed block 322 is disposed at the opening of the channel 3231 on one side of the rotating channel 3211. During the transition from the tightening process to the pressure-holding process, or from the pressure-holding process to the loosening process, the driving gear 312 moves to the opening of the channel 3231 of the rotating channel 3211 and abuts against the fixed block 322. The fixed block 322 limits the driving gear 312, preventing it from falling off the rotating channel 3211. The fixed block 322 also serves to position the driving gear 312. When the two abut against each other, the engaging member is completely separated from the limiting channel 3221, or the engaging member is completely inserted into the limiting channel 3221, ensuring more accurate and smooth switching between the tightening process, the pressure-holding process, and the loosening process.

[0056] In this embodiment, the fixed block 322 is located at the front end of the rotating block 321. That is, during the tightening process, the driving handle 31 is located at the front end position, the driving gear 312 is located at the front end position of the rotating channel 3211, and the engaging member is located at the front end of the limiting channel 3221 and is separated from the limiting channel 3221, so that the driving handle 31 can rotate and drive the first clamp body 1 and the second clamp body 2 to approach each other and clamp. When the tightening process is transformed into the pressure holding process, the driving handle 31 is pulled back so that the driving gear 312 is located at the rear end position of the rotating channel 3211, and the engaging member is located in the limiting channel 3221, so that the engaging member and the limiting member are mutually engaged and limited. In the pressure holding state, the driving handle 31 is located at the rear end position, that is, there is a large distance between the protrusion 313 at the end of the driving handle 31 and the limiting cylinder 11. When the pressure holding process is transformed into the releasing process, the driving handle 31 is pushed forward so that the driving gear 312 is located at the front end of the rotating channel 3211, and the engaging part is located at the front end of the limiting channel 3221 and is separated from the limiting channel 3221, so that the driving handle 31 can rotate in the opposite direction to release the scalp trauma hemostatic clamp.

[0057] Similarly, the fixed block 322 can also be located at the rear end of the rotating block 321. That is, during the tightening process, the driving handle 31 is located at the rear end, the driving gear 312 is located at the rear end of the rotating channel 3211, and the engaging member is located at the rear end of the limiting channel 3221 and is separated from the limiting channel 3221, allowing the driving handle 31 to rotate, driving the first clamp body 1 and the second clamp body 2 to approach each other and clamp. When the tightening process transitions to the pressure holding process, the driving handle 31 is pushed forward so that the driving gear 312 is located at the front end of the rotating channel 3211 and the engaging member is located within the limiting channel 3221, achieving mutual engagement and limiting between the engaging member and the limiting member. In the pressure holding state, the driving handle 31 is located at the front end, that is, the protrusion 313 at the end of the driving handle 31 is close to the limiting cylinder 11. By controlling the overall length of the driving handle 31, it is possible to achieve abutment and contact between the protrusion 313 and the limiting cylinder 11 in the pressure holding state, thereby reducing the exposed length of the driving handle 31 in the pressure holding state. Furthermore, the length of the limiting cylinder 11 can be extended, and an opening can be provided at the end of the limiting cylinder 11, so that when in the pressure-holding state, the driving handle 31 completely enters the opening of the limiting cylinder 11, thereby concealing the driving handle 31. When transitioning from the pressure-holding process to the release process, the driving handle 31 is pulled back, so that the driving gear 312 is located at the rear end of the rotation channel 3211, and the engaging member is located at the rear end of the limiting channel 3221 and separated from the limiting channel 3221, allowing the driving handle 31 to rotate in the opposite direction, releasing the scalp trauma hemostatic clamp. This allows the driving handle 31 to be located at the front end during the engagement process, reducing the exposed length of the driving handle 31 and preventing accidental operation of the driving handle 31.

[0058] In this embodiment, a plane bearing 5 is fixed between the opposite sides of the rotating block 321 and the fixed block 322. The plane bearing 5 effectively reduces the friction between the rotating block 321 and the fixed block 322, making the scalp trauma hemostatic clamp more labor-saving during the tightening and loosening processes.

[0059] In this embodiment, two limiting cylinders 11 are spaced apart at either end of one side of the first clamp body 1. Two sets of rotation limiting assemblies are provided, each housed within one of the two limiting cylinders 11. The drive handle 31 passes through the two limiting cylinders 11 and protrudes from them. The provision of two limiting cylinders 11 at the front and rear ends of the first clamp body 1 effectively reduces the length of the rotating block 321 and the fixed block 322, thereby reducing the weight of the scalp trauma hemostatic clamp and preventing it from falling due to its own weight, which could affect the hemostatic clamping process.

[0060] In this embodiment, one end of the driving handle 31 is provided with a protrusion 313 extending outward. The protrusion 313 is located outside the limiting cylinder 11. The driving handle 31 is driven to rotate by the protrusion 313, which is more labor-saving.

[0061] Please refer to Figure 1 and Figure 2 As shown, the bite needles 4 on the first clamp body 1 and the bite needles 4 on the second clamp body 2 are staggered. The staggered bite needles 4 evenly apply closing force to both sides of the wound in two directions, which has a good clamping and hemostatic effect. The bite needles 4 are straight needles, and the bottom ends of the bite needles 4 of the first clamp body 1 and the second clamp body 2 are tilted toward each other. Similarly, the bite needles 4 can be curved needles, and the needle tips of the bite needles 4 of the first clamp body 1 and the second clamp body 2 are bent toward each other, and the needle tips are inserted into the scalp to fix the hemostatic clamp on the scalp. The curved needle can more easily hook the skin and subcutaneous tissue, and has a good hooking and limiting effect.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
