TECHNICAL FIELD
[0001] The present application belongs to the technical field of medical devices, especially to the field of hemostatic devices, and in particular to a clamping hemostatic device that can be set and adjusted by one hand. BACKGROUND
[0002] In clinical practice, for body surface bleeding or limb bleeding, the proximal part of the wound is often tightly tied by a hemostatic device to stop bleeding, but this method of hemostasis can easily block the normal blood supply of the tissue, and long-term hemostasis can easily cause ischemia in the distal part. If direct compression hemostasis is used at the wound site, the above problems can be effectively solved.
[0003] How to effectively and continuously compress and hemostasis for body surface and limb bleeding, there are clamping hemostatic devices in the prior art CN202410352041-Instantaneous closing wound pressure adjustable elastic clamping hemostatic device and CN202311766175-Pressure adjustable dynamic gripping compression hemostatic device; the above two hemostatic devices are clamping hemostatic devices for body surface and limb bleeding, but the natural initial state of the two technologies is to use elastic force to make the two clamping hemostatic parts in a clamped state. After the distance between the two clamping operation parts is controlled to be reduced under the action of external force, the clamping hemostatic parts are separated and set on the bleeding site of the patient. Then, the elastic clamping force of the elastic structure between the clamping hemostatic parts and the clamping operation parts makes the clamping hemostatic parts contact the patient's skin. The hemostatic pressure after contact depends on the elastic clamping force of the elastic structure, but the hemostatic pressure in this state is insufficient, so it is necessary to further set a pressure regulating structure between the two clamping operation parts to increase the distance between the two clamping operation parts by the opening force to adjust the pressure to make up for the insufficient elastic clamping force of the elastic structure. When the pressure is too large, the pressure is further reduced by adjusting the pressure regulating structure in the opposite direction; the above technical solution can hemostasis the bleeding part, but the entire operation process is divided into two steps of setting the structure to the patient's bleeding part by using external force and adjusting the pressure, and the entire placement and pressure adjustment operation process is not synchronized and needs to be completed by two hands in many cases.
[0004] But the two-step process takes a long time, and the two-handed operation consumes a lot of manpower; therefore, a clamping hemostatic device that can be completed by one hand is needed to solve the above problems, specifically a clamping hemostatic device that can be set and adjusted by one hand. SUMMARY
[0005] The prior art needs two steps to complete the clamping hemostasis by hemostatic clips, and the pressure adjusting structure needs to be adjusted by two hands. It is difficult to complete the pressure adjusting action by one hand, and even if it is completed, it is difficult. In an emergency, the setting time of the entire structure is greatly increased, especially the clamping hemostasis structure is also provided with a contact type balloon. The position of the balloon may need to be adjusted due to inaccuracy, and after adjustment, the pressure needs to be adjusted again. Because each operation needs to be completed by two hands, the entire operation needs to be repeatedly operated by one person or completed by multiple persons, resulting in that the prior art scheme consumes more time or personnel when in use.
[0006] Therefore, the inventor expects to design a technical scheme that can complete the setting of the clamping hemostasis instrument to the bleeding site and simultaneously complete the pressure adjustment by one hand when performing the clamping operation. If this technical concept is selected, the technical scheme of the initially closed clamping hemostasis part cannot be implemented because it can only be opened under external force. However, the pressure adjusting process is the tendency of the clamping hemostasis part to close. The directions of the two forces are opposite, so it is impossible to achieve the closing of the clamping hemostasis part while providing external force by one hand. Therefore, a technical scheme is needed in which the directions of the external force and the closing force of the clamping hemostasis part are the same. Therefore, the inventor thinks of a technical scheme in which the clamping hemostasis part and the clamping operation part connected together are arranged on the left and right sides, two groups of structures form an intersection to constitute a same large or small technical scheme, and a locking structure that locks the clamping state at any time during the clamping action is arranged. Of course, during the process, it also needs to consider how to ensure that the pressure reduction adjusting process is completed by one hand in the reverse adjusting process. This technical scheme undoubtedly satisfies the one-handed pressure and pressure reduction operation of the clinician, frees the other hand of the clinician, ensures the cooperation of other operations, greatly saves the time of the clinician, reduces the manpower, and quickly and effectively completes the clamping hemostasis and reverse pressure reduction fine adjustment of the patient according to the pressure.
[0007] The specific technical scheme is as follows: a clamping hemostasis instrument completed by one hand; the clamping hemostasis instrument comprises:
[0008] The clamping unit one comprises a clamping hemostasis part one and a clamping operation part one.
[0009] The clamping unit two comprises a clamping hemostasis part two and a clamping operation part two; the clamping unit two and the clamping unit one are arranged in an intersection, and a first rotating shaft is arranged at the intersection position.
[0010] The reset spring is arranged at the intersection position of the clamping unit one and the clamping unit two, and the reset spring provides a force for driving the clamping unit one and the clamping unit two to rotate and separate at both ends.
[0011] The first clamping and hemostatic part and the second clamping and hemostatic part are used to contact the skin for hemostasis, and the first clamping operation part and the second clamping operation part are used to provide an operating position for an operator;
[0012] An instant locking structure is used to lock the position relationship between the first clamping operation part and the second clamping operation part when an external force applied to the first clamping operation part and the second clamping operation part disappears or is insufficient during the clamping action of the mutual approach of the first clamping operation part and the second clamping operation part;
[0013] A locking release structure is arranged on the first clamping operation part or the second clamping operation part, and is used to adjust the state of the instant locking structure by an external force to release the position locking of the instant locking structure on the first clamping operation part and the second clamping operation part when reverse adjustment or recovery of the initial state is required. The force direction to the locking release structure during the release of the locking is the same as or opposite to the force direction to the first clamping operation part or the second clamping operation part during the clamping action.
[0014] The force position to the locking release structure is close to the force position to the first clamping operation part or the second clamping operation part, which is used to ensure that the force to the first clamping operation part, the second clamping operation part and the locking release structure is adjusted by a single hand to finally ensure that the clamping action of the first clamping operation part and the second clamping operation part is completed by the force, and the adjustment action of pressure increase and the adjustment action of taking down the entire device are completed.
[0015] Note: The initial state is the open state of the two clamping units away from each other, and the recovery of the initial state is the recovery from the clamping state to the open state. In a specific scene, when the hemostatic device needs to be taken down from the hemostatic part, the locking needs to be released to recover
[0016] How to effectively set the instant locking structure and the locking contact structure to ensure that the force direction to the locking release structure during the release of the locking is the same as or opposite to the force direction to the first clamping operation part or the second clamping operation part during the clamping action, and the force position to the locking release structure is close to the force position to the first clamping operation part or the second clamping operation part, which is the core problem of completing the task of single-handed operation. The following technical features are used to solve the above problems.
[0017] The instant locking structure includes:
[0018] The long strip through hole is arranged on the first clamping operation part;
[0019] An arc-shaped rack is fixedly installed inside the second clamping operation part and extends towards the first clamping operation part; the center of the arc-shaped rack is on the rotation axis of the first and second clamping units; during clamping operation, the arc-shaped rack moves as it passes through the through hole of the long strip.
[0020] The elastic locking structure includes 1-5 sets of teeth that mesh with the arc-shaped rack to achieve position locking; under non-external force control, when the clamping operation part one and the clamping operation part two approach each other during the clamping action, the teeth of the elastic locking structure mesh with the teeth of the arc-shaped rack.
[0021] The locking release structure controls the positional change of the elastic locking structure, causing the teeth of the elastic locking structure and the teeth of the arc-shaped rack to switch between an engaged locking state and a non-engaged locking state.
[0022] By setting the center of the arc-shaped rack on the rotating shaft, the position of the arc-shaped rack and the through hole of the long strip can be kept unchanged, thus relatively fixing the elastic locking structure and the locking contact structure. The toothed elastic locking structure that meshes with the arc-shaped rack can achieve instant locking. The teeth of the arc-shaped rack are inclined towards the clamping operation part. This setting ensures that it can rotate in the direction that the two clamping operation parts move closer to each other, and immediately lock the position relationship after stopping the force when the appropriate position is reached.
[0023] Furthermore, the distance between the upper side of the elongated through hole and the end of the clamping operation part away from the rotating shaft is greater than 8mm; this setting can ensure that an effective clamping operation space is retained on the clamping operation part, and the locking release structure can be operated by adjusting the finger position, without the operating force changing too much due to the shortening of the lever arm.
[0024] Furthermore, the locking release structure includes an inclined, protruding portion outside the elongated through-hole, and a second portion that abuts against or is directly connected to the elastic locking structure. The toothed portion of the elastic locking structure releases the lock by rotation. The portion outside the hole is connected to the second portion, and the control mechanism allows the portion outside the hole to enter the elongated through-hole and move together with the second portion, driving the toothed portion of the elastic locking structure to rotate, thus releasing the engagement of the teeth of the elastic locking structure with the teeth of the arc-shaped rack. This method ensures that the locking release structure moves outside the elongated through-hole and along a path close to the clamping operation part, thereby releasing the lock.
[0025] Furthermore, an elastic locking structure is provided on the clamping operation part one, including an elastic reset structure, an engagement structure, and a second rotating shaft. The engagement structure is provided with teeth that engage with the arc-shaped rack to achieve position locking. The second rotating shaft is located in the elongated through hole. The engagement structure is wholly or partially located in the elongated through hole, and the engagement structure rotates through the rotating shaft. In the absence of external force, the elastic reset structure maintains the contact between the engagement structure and the arc-shaped rack. The rotating shaft is perpendicular to the long side wall of the elongated through hole.
[0026] Furthermore, the elastic reset structure has a fixed end at one end and an abutting end at the other. The fixed end is fixedly mounted on the clamping operation part, while the abutting end abuts against the engaging structure. Except for the fixed end, the other parts are freely disposed within the elongated through hole. This arrangement allows most of the structure to be housed within the elongated through hole, effectively saving installation space.
[0027] Furthermore, the elastic reset structure is a metal elastic sheet structure, which includes a guide portion, an abutment portion, and a connection between the guide portion and the abutment portion via a bent portion, all extending axially along the through hole of the elongated strip. The guide portion is fixed at the upper edge of the through hole of the elongated strip. The teeth of the meshing structure and the abutment portion are located on both sides of the second rotating shaft. This arrangement allows for convenient fixing of the elastic sheet to the clamping operation part, providing good fixation and ensuring effective elastic force. The bent portion further enhances the elastic buffering effect during operation, preventing damage to the elastic structure caused by direct contact.
[0028] Furthermore, the engagement structure extends away from the arc-shaped rack, reaching the outside of the long through hole to form a locking release structure; the engagement structure and the locking release structure are integrally connected, forming a rotating plate that can rotate along the axis within the long through hole. This arrangement ensures that the direction of the force applied during locking release is the same as or opposite to the direction of the force applied during clamping.
[0029] Alternatively, a locking release structure can be provided on the clamping operation part one opposite the elastic reset structure. The locking release structure includes an elastic pressing piece inclinedly disposed outside the elongated through hole and an abutment release structure connected to the elastic pressing piece. The abutment release structure abuts against the engaging structure. One end of the elastic pressing piece is fixed to the clamping operation part one, and the other end is integrally connected to the abutment release structure. By pressing the elastic reset structure towards the clamping operation part one, the engaging structure disengages from the arc-shaped rack.
[0030] Furthermore, while ensuring effective rotation of both clamping operation part one and clamping operation part two, the arc-shaped rack is positioned as close as possible to the inner side of clamping operation part one, as close as possible to the rotating shaft one. The overall length of clamping operation part one is required to ensure that the maximum opening distance is within the range controllable by one hand.
[0031] Furthermore, the meshing structure comprises two sections arranged at an angle: a first section with teeth and a second section connecting the locking and releasing structure. A pivot or pivot hole on the meshing structure is located at the connection point of the two sections, less than 5mm from the edge. The first section with teeth extends to the outside of the elongated through-hole, and the second section also partially extends to the outside of the elongated through-hole. The locking and releasing structure is constructed by extending the meshing structure. This arrangement effectively ensures the stability of the structure itself, provides space for multiple teeth, and effectively maintains the meshing effect, ensuring a valid locking state. Furthermore, by extending both sections to the outside of the elongated through-hole, the required length of the meshing structure is shortened, thereby shortening the overall length of the clamping operation section and reducing the maximum operating distance between clamping operation section one and clamping operation section two, thus reducing operational difficulty. Furthermore, to improve the locking effect after the meshing structure engages with the arc-shaped rack, 3-5 sets of teeth are provided on the meshing structure.
[0032] Technical effect
[0033] By having clamping unit one and clamping unit two initially in an open state, it is possible to easily place hemostatic instruments at the bleeding site.
[0034] By setting up an instant locking structure and a locking release structure, and using external force to control the locking release structure to adjust the instant locking structure's state, the instant locking structure releases the position lock of clamping operation part one and clamping operation part two. When releasing the lock, the direction of force applied to the locking release structure is the same as or opposite to the direction of force applied to clamping operation part one or clamping operation part two when the locking release structure is set during the clamping action. Furthermore, the force applied to the locking release structure is close to the force applied to clamping operation part one or clamping operation part two when the locking release structure is set. This allows for simultaneous application of force to clamping operation part one, clamping operation part two, and the locking release structure by adjusting the coordination of different fingers with a single hand. This ensures that the clamping action is completed by applying force to clamping operation part one and clamping operation part two, and allows for adjustments when increasing pressure or removing the entire instrument. The entire operation process is simple and convenient.
[0035] By setting an elongated through hole, and surrounding the arc-shaped rack of the instant locking structure, the elastic locking structure, and the locking release structure, the arc-shaped rack passes through the elongated through hole, and the arc-shaped rack is engaged and locked within the elongated through hole; the locking release structure set next to the hole releases the engagement and lock to adjust the pressure; ultimately, all the necessary structures are achieved so that clamping and locking actions can be performed by adjusting with one hand.
[0036] While ensuring the effective rotation of clamping operation part one and clamping operation part two, by setting the arc-shaped rack as close as possible to the inside of clamping operation part one on the rotating shaft, the length of the arc-shaped rack and the overall length requirement of clamping operation part one can be effectively reduced, ensuring that the maximum opening distance is within the range that can be controlled by one hand.
[0037] By effectively shaping the meshing structure of the elastic locking mechanism, it can meet the needs of meshing locking and rotation unlocking with a shorter length, and can also shorten the length of the clamping operation part to a certain extent, thus better ensuring one-handed operation.

[0054] refer to Figures 1-2 ;11-12;A clamping hemostatic device that can be set and adjusted with one hand; comprising:
[0055] Clamping unit one includes clamping hemostasis part one 21 and clamping operation part one 11; clamping unit two includes clamping hemostasis part two 22 and clamping operation part two 12; clamping unit two and clamping unit one are arranged crosswise, and a first rotating shaft 32 is provided at the intersection position;
[0056] A return spring 31 is located at the intersection of clamping unit one and clamping unit two. The return spring 31 provides a force that drives both ends of clamping unit one and clamping unit two to rotate and separate. The return spring 31 is sleeved on the first rotating shaft 32.
[0057] The clamping hemostatic part 1 21 and the clamping hemostatic part 2 22 are used to cooperate in contact with the skin for hemostasis, and the clamping operation part 1 11 and the clamping operation part 2 12 are used to provide the operator's operation position;
[0058] The instant locking structure is used to lock the positional relationship between clamping operation part 11 and clamping operation part 2 12 when the external force applied to clamping operation part 11 and clamping operation part 2 disappears or is insufficient during the clamping action of clamping operation part 11 and clamping operation part 2 12 approaching each other.
[0059] A locking release structure is provided on clamping operation part one 11 or clamping operation part two 12. When reverse adjustment is required or the instrument needs to be removed from the bleeding site, external force controls the locking release structure to adjust the instant locking structure state and release the instant locking structure from locking the position of clamping operation part one 11 and clamping operation part two 12. When the lock is released, the direction of the force applied to the locking release structure is the same as or opposite to the direction of the force applied to clamping operation part one 11 or clamping operation part two 12 with the locking release structure during the clamping action.
[0060] Furthermore, the force application position applied to the locking release structure is close to the force application position applied to the clamping operation part 11 or clamping operation part 2 12 where the locking release structure is located. This is to ensure that by adjusting the coordination relationship of different fingers with a single hand, force can be applied to clamping operation part 11, clamping operation part 2 12 and locking release structure simultaneously. This ensures that the clamping action is completed by applying force to clamping operation part 11 and clamping operation part 2 12, and the adjustment action is performed when the pressure needs to be increased and the entire instrument is removed.
[0061] The specific implementation of the instant locking structure is as follows: The instant locking structure includes:
[0062] A long through hole 41 is provided on the clamping operation part 11;
[0063] The arc-shaped rack 42 is fixedly installed inside the clamping operation part 2 12 and extends towards the clamping operation part 1 11; the center of the arc-shaped rack 42 is on the rotation axis of the clamping unit 1 and the clamping unit 2; during the clamping operation, the arc-shaped rack 42 moves through the long through hole 41.
[0064] The elastic locking structure includes 1-5 sets of teeth 4321 that mesh with the arc-shaped rack 42 to achieve position locking; under non-external force control state, when the clamping operation part 11 and the clamping operation part 2 12 approach each other during the clamping action, the teeth 4321 of the elastic locking structure mesh with the teeth 4321 of the arc-shaped rack 42.
[0065] The locking release structure is used to control the positional change of the elastic locking structure, so that the teeth 4321 of the elastic locking structure and the teeth 4321 of the arc rack 42 switch between the engaged locking state and the non-engaged locking state.
[0066] By setting the center of the arc-shaped rack 42 on the rotating shaft, the positions of the arc-shaped rack 42 and the through hole 41 remain unchanged, thus relatively fixing the elastic locking structure and the locking contact structure. The elastic locking structure with teeth 4321 meshing with the arc-shaped rack 42 can achieve immediate locking. The teeth 4321 of the arc-shaped rack 42 are inclined towards the clamping operation part 12. This setting ensures that it can rotate towards the direction in which the two clamping operation parts move closer to each other, and immediately locks the position relationship after stopping the force when the appropriate position is reached.
[0067] A more preferred embodiment is that the distance between the upper side of the elongated through hole and the end of the clamping operation part away from the rotating shaft is greater than 8mm; this setting can ensure that an effective clamping operation space is retained on the clamping operation part 11, and the locking release structure can be operated by adjusting the finger position, without the operating force changing too much due to the shortening of the lever arm.
[0068] A more preferred embodiment is that the locking release structure includes an external portion that protrudes obliquely from the elongated through hole 41, and a second portion that abuts against the elastic locking structure or is directly connected to the elastic locking structure; the external portion is connected to the second portion, and the external portion is controlled to enter the hole and move together with the second portion; the toothed portion of the elastic locking structure 4321 is unlocked by rotation, driving the toothed portion of the elastic locking structure 4321 to rotate, and releasing the toothed portion of the elastic locking structure 4321 from engaging with the toothed portion of the arc-shaped rack 42.
[0069] A more preferred embodiment is that the elastic locking structure is provided on the clamping operation part 11, including an elastic reset structure 431, an engagement structure 432 and a second rotating shaft 433. The engagement structure 432 is provided with teeth 4321 that engage with the arc-shaped rack 42 to achieve position locking. The second rotating shaft 433 is provided in the elongated through hole. The engagement structure 432 is wholly or partially provided in the elongated through hole, and the engagement structure 432 rotates through the rotating shaft. In the absence of external force, the elastic reset structure 431 maintains the engagement structure 432 in contact with the arc-shaped rack 42. The rotating shaft is perpendicular to the long side wall of the elongated through hole 41.
[0070] A more preferred embodiment is that the elastic reset structure 431 has a fixed end at one end and an abutting end at the other. The fixed end is fixedly mounted on the clamping operation part, and the abutting end abuts against the engagement structure 432. Except for the fixed end, the other parts of the elastic reset structure 431 are freely disposed beside or inside the elongated through hole 41. This arrangement allows most of the structure to be housed beside and inside the elongated through hole 41, effectively saving installation space. Finally, the elongated through hole 41 is positioned near the top of the clamping operation part 11, ensuring the feasibility of single-handed operation.
[0071] A more preferred embodiment is that the elastic reset structure 431 is a metal elastic sheet structure, which includes a guide portion 4311, an abutment portion 4313, and the guide portion 4311 and the abutment portion 4313 connected by a bent portion 4312, all extending axially along the through hole 41. The guide portion 4311 is fixed at the upper edge of the through hole 41. The teeth 4321 of the meshing structure 432 and the abutment portion 4313 are located on both sides of the second rotating shaft 433. This arrangement allows for convenient fixing of the elastic sheet to the clamping operation part 11, providing good fixation and ensuring effective elastic force. The bent portion 4312 further enhances the elastic buffering effect during operation, preventing damage to the elastic structure from direct contact. A more preferred embodiment is... (Refer to...) Figure 9 In order to provide elasticity to the elastic reset structure 431, two abutting portions 4313 are provided on the guide portion 4311; both are connected by the bending portion 4312.
[0072] A more preferred embodiment is, referring to Figures 2-4 The engagement structure 432 extends away from the arc-shaped rack 42, reaching the outside of the elongated through hole 41 to form a locking release structure. The engagement structure 432 and the locking release structure are integrally connected, forming a rotating plate that can rotate along the axis within the elongated through hole 41. This arrangement ensures that the direction of the force applied during locking release is the same as or opposite to the direction of the force applied during clamping.
[0073] A more preferred embodiment is that the locking release structure further includes a pressing plate 51 disposed perpendicular to the rotating plate. The pressing plate 51 is slotted or elliptical, which increases the comfort of pressing to unlock.
[0074] Or, refer to Figures 5-6A locking release structure is provided on the clamping operation part 11 opposite to the elastic reset structure 431. The locking release structure includes an elastic pressing piece 52 inclinedly disposed outside the elongated through hole 41 and an abutment release structure 53 connected to the elastic pressing piece. The abutment release structure 53 abuts against the engaging structure 432. One end of the elastic pressing piece 52 is fixed to the clamping operation part 11, and the other end is integrally connected to the abutment release structure 53. By pressing the elastic reset structure 431 toward the clamping operation part 11, the engaging structure 432 disengages from the arc-shaped rack 42.
[0075] A more preferred embodiment is that, while ensuring effective rotation of the first clamping operation part 11 and the second clamping operation part 12, the arc-shaped rack 42 is positioned as close as possible to the inner side of the first clamping operation part 11, near the first rotating shaft. The overall length of the first clamping operation part 11 is required to ensure that the maximum opening distance is within the range that can be controlled by one hand.
[0076] A more preferred embodiment is, referring to Figures 8-9 Each clamping operation part has a rectangular opening near the end of the rotating shaft, defined as rectangular opening 1 61 and rectangular opening 2 62. The width of rectangular opening 1 61 is larger than that of rectangular opening 2 62. The width of rectangular opening 1 61 is greater than the overall width of the clamping operation part with rectangular opening 2 62. This arrangement is used to facilitate the cross combination of the two clamping operation parts through rectangular opening 1 61. The rotating shaft passes through rectangular opening 1 61 and rectangular opening 2 62. A return spring 31 is installed inside rectangular opening 2 62.
[0077] A more preferred embodiment is that the arc-shaped toothed plate is disposed on the clamping operation part where the rectangular opening 61 is located, and the arc-shaped toothed plate is positioned above the rectangular opening 61 at a distance not exceeding 5 mm; the elongated through hole 41 is disposed on the clamping operation part where the rectangular opening 62 is located. This arrangement can reduce the overall length of the clamping operation part, avoiding situations where operators with smaller hands cannot complete the operation due to excessive distance at the ends. It can also maintain the stability of the clamping hemostatic instrument structure and prevent the distance between the elongated through hole 41 and the rectangular opening 62 from being too small.
[0078] A more preferred embodiment is provided for reference. Figures 7-10The meshing structure 432 includes two sections arranged at an included angle: a first section 4322 with teeth 4321 and a second section 4323 connecting the locking and releasing structure. A pivot or pivot hole on the meshing structure 432 is located at the connection point of the two sections, less than 5mm from the edge. The first section 4322 with teeth 4321 extends to the outside of the elongated through hole 41, and the second section 4323 also partially extends to the outside of the elongated through hole 41. The locking and releasing structure is constructed by extending the meshing structure 432; specifically, a locking and releasing structure is provided on the second section 4323... The vertical pressing plate 51, the second section structure 4323 connected to the pressing structure, and the pressing structure together form a complete locking and releasing structure. This arrangement effectively ensures the stability of the structure itself, provides space for the multi-tooth 4321, and effectively achieves a meshing effect, ensuring an effective meshing and locking state. Furthermore, by introducing both sections of the structure to the outside of the elongated through hole 41, the required length of the meshing structure 432 can be shortened, thereby shortening the overall length of the clamping operation section and reducing the maximum operating distance between the first clamping operation section 11 and the second clamping operation section 12, thus reducing the difficulty of operation. A more preferred embodiment is that, to improve the locking effect after the meshing structure 432 engages with the arc-shaped rack 42, 3-5 sets of teeth 4321 are provided on the meshing structure 432.
[0079] A more preferred embodiment is, referring to Figures 11-13 The clamping hemostasis part 1 21 and the clamping hemostasis part are curved structures; the curved panel 72 creates an effective clamping space and can also improve the clamping effect; the clamping operation part 1 11 and the clamping operation part 2 12 are inclined handle-type structures set in the middle of the clamping hemostasis part 1 21 and the clamping hemostasis part 2 22; the operation is more convenient by operating the inclined handle.
[0080] A more preferred embodiment is that the maximum width of the clamping hemostasis operation part one and the clamping operation part two 12 is not greater than half the width of the clamping hemostasis part one 21, and the widths of the clamping hemostasis part one 21 and the clamping hemostasis part two 22 are the same.
[0081] A more preferred embodiment is that the ends of the first clamping hemostatic part 21 and the second clamping hemostatic part 22 are provided with piercing needles 71 that are convenient to penetrate the skin and improve clamping stability. The piercing needles 71 on the first clamping hemostatic part 21 and the second clamping hemostatic part 22 are arranged alternately. This arrangement makes it convenient to grasp the skin evenly and stably.
[0082] A more preferred embodiment is that, except for the different placement of the insertion needle 71, the clamping hemostasis part one 21 and the clamping hemostasis part two 22 are set in the same way. Taking the clamping hemostasis part one 21 as an example, the structure is described as follows: the clamping hemostasis part one 21 includes a curved panel 72 connected to the clamping operation part one 11, and also includes a plurality of spacers 73 arranged side by side along the edge of the curved panel 72 with the first end connected to the curved panel 72 and the second end connected to the insertion needle 71.
[0083] A more preferred embodiment is that the spacer 73 continues to extend along the bending direction of the curved panel 72 connected to it, and the insertion needle 71 is a short straight needle, which is arranged tangentially to the spacer 73 where the insertion needle 71 is located. This arrangement ensures that the insertion needle 71 can effectively penetrate the skin.
[0084] A more preferred embodiment is that the insertion needle 71 is positioned in the middle of the plane on which the spacer plate 73 is positioned, and the diameter of the insertion needle 71 is less than or equal to the diameter of the inscribed circle in the plane. This arrangement can prevent the spacer plate 73 from penetrating the skin along with the insertion needle 71, so that the insertion needle 71 only plays the role of holding and stabilizing, and will not cause excessive damage to the skin.
[0085] A more preferred embodiment is that when the clamping hemostatic device is applied to different animals, it can be set according to the skin thickness of different animals. When applied to humans, the length of the insertion needle is less than 2mm.
[0086] A more preferred embodiment is that the first end of the spacer 73 is the end where the insertion needle 71 is disposed, and the cross-section of the first end of the spacer 73 is set into a trapezoidal shape, with the trapezoidal side closer to the first end being the short side and the trapezoidal side farther from the first end being the long side. This arrangement ensures that although the spacer 73 cannot be inserted into the skin, the gradually changing size ensures that the first end of the spacer 73 is deeply embedded in the skin and that the insertion needle 71 is inserted into the skin to form a gripping force.
[0087] A more preferred embodiment is, referring to Figure 14 To effectively protect the insertion needle 71, which holds the hemostatic instrument, before use and prevent contamination and accidental injury, a needle protector 74 is provided. The needle protector 74 has a corresponding insertion channel for the needle. The first end of the needle protector 74 is a straight horizontal plane, and the second end of the needle protector 74 fits into the trapezoidal cross-section of the adjacent spacer 73. This design effectively protects the needle.
[0088] A hemostatic balloon is placed inside the clamping hemostatic part. The balloon shape can be selected to match the shape of the inside of the clamping hemostatic part. Alternatively, a suitable balloon can be temporarily placed inside the clamping hemostatic part to complete hemostasis, depending on the size of the bleeding area. Since the hemostatic balloon is an existing technology for long bones, the balloon is not shown in the figure.
