Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular to the field of hemostatic devices, and specifically is a clamping hemostatic device that can be set and adjusted by one hand. Background Art

[0002] In clinical practice, for bleeding on the body surface or bleeding in the limbs, hemostatic devices are often used to tie the proximal end of the wound to stop bleeding. However, the above hemostatic method is likely to block normal blood circulation in the tissue, and long-term hemostasis is prone to distal ischemia. If compression hemostasis can be used directly on the wound, the above problem will be effectively solved.

[0003] How to effectively and continuously compress and stop bleeding on the body surface and limbs? In the prior art, there are clamping hemostatic devices CN202410352041-a pressure-adjustable elastic clamping hemostatic device for instant wound closure and CN202311766175-a pressure-adjustable dynamic grasping compression hemostatic device; the above two hemostatic devices are clamping hemostatic methods for bleeding on the body surface and limbs, but the natural initial state of the two technologies is to use elastic force to make the two clamping hemostatic parts in a clamping state, and under the action of external force, the distance between the two clamping operating parts is controlled to be reduced so that the clamping hemostatic parts are separated and set to the bleeding position of the patient, and then the elastic structure between the clamping hemostatic part and the clamping operating part is used to release the hemostatic part. The elastic clamping force makes the clamping hemostatic part contact the patient's skin. The hemostatic pressure after contact depends on the elastic clamping force of the elastic structure. However, the hemostatic pressure in this state is insufficient. Therefore, it is necessary to use the pressure regulating structure arranged between the two clamping operation parts to increase the distance between the two clamping operation parts by the stretching force to adjust the pressure so as to make up for the insufficient elastic clamping force of the elastic structure. When the pressure is too large, the pressure regulating structure is adjusted in the reverse direction to slightly reduce the pressure. Although the above technical scheme can stop bleeding in the bleeding part, the whole operation process is divided into two steps: using external force to open the structure and set it to the bleeding part of the patient and adjusting the pressure. The whole placement and pressurization operation process is not synchronized and in many cases both hands are needed to complete the operation.

[0004] However, the step-by-step process takes a long time, and the two-handed operation consumes a lot of manpower. Therefore, a clamping hemostatic instrument that can be completed with one hand is needed to solve the above problems, specifically a clamping hemostatic instrument that can be set and adjusted with one hand. Summary of the invention

[0005] According to the prior art, it takes two steps to complete clamping hemostasis with a hemostatic clamp, and the pressure regulating structure often requires the cooperation of both hands to complete the pressure regulating action. It is difficult to complete it with one hand alone, and even if it is completed, the difficulty is relatively large. In an emergency, the setting time of the entire structure is greatly increased, especially the clamping hemostatic structure is also provided with a contact balloon, which may need to be adjusted due to inaccurate balloon position. After the adjustment, the pressure needs to be readjusted. Because each operation requires both hands, the entire operation requires one person to perform the operation repeatedly, or it needs to be completed with the assistance of multiple people, resulting in the prior art solution consuming more time or personnel when in use.

[0006] Therefore, in order to solve the above problems, the inventor hopes to design a technical solution that can complete the setting of the clamping hemostatic instrument to the bleeding site and complete the pressure regulation with one hand during the clamping operation. If this technical concept is selected, the technical solution of the clamping hemostatic part whose initial natural state is closed cannot be realized, because it can only be opened under the action of external force, but the pressure regulation process tends to close the clamping hemostatic part as much as possible. The two force directions are opposite, and it is impossible to achieve the closure of the clamping hemostatic part while providing external force with one hand. Therefore, it is necessary to provide a technical solution in which the direction of the external force is in the same direction as the force required for the closing direction of the clamping hemostatic part. Therefore, the inventor thought of arranging the connected clamping hemostatic part and the clamping operation part on the left and right sides, and the two groups of structures form a cross to form a technical solution of the same size, and then set a locking structure to lock the clamping state at any time when the clamping action is performed; of course, the process also needs to consider how to ensure that the pressure reduction adjustment process is completed with one hand during reverse adjustment. Such a technical solution undoubtedly satisfies the clinician's one-handed pressure and decompression operations, freeing the doctor's other hand to ensure its cooperation in other operations. This will greatly save the doctor's time, reduce manpower, and quickly and effectively complete clamping hemostasis for the patient and perform reverse decompression fine-tuning according to the pressure.

[0007] The specific technical solution is: a clamping hemostatic device that can be set and adjusted with one hand; it includes: A clamping unit 1, comprising a clamping hemostasis part 1 and a clamping operation part 1; The clamping unit 2 includes a clamping hemostasis part 2 and a clamping operation part 2; the clamping unit 2 and the clamping unit 1 are arranged crosswise, and a first rotating shaft is arranged at the crossing position; A return spring is arranged at the intersection of the clamping unit 1 and the clamping unit 2, and the return spring provides a force to drive both ends of the clamping unit 1 and the clamping unit 2 to rotate and separate; The first clamping hemostasis part and the second clamping hemostasis part are used to cooperate with each other to contact the skin to stop bleeding, and the first clamping operation part and the second clamping operation part are used to provide an operating position for the operator; The instant locking structure is used for instantly locking the positional relationship between the clamping operation part 1 and the clamping operation part 2 when the external force applied to the clamping operation part 1 and the clamping operation part disappears or is insufficient when the clamping operation part 1 and the clamping operation part 2 are in a clamping action close to each other; The locking release structure is arranged on the clamping operation part one or the clamping operation part two, and is used to control the locking release structure by external force to adjust the state of the instant locking structure when reverse adjustment or restoration of the initial state is required, and to release the position lock of the clamping operation part one and the clamping operation part two by the instant locking structure. The direction of force applied to the locking release structure during unlocking is the same as or opposite to the direction of force applied to the clamping operation part one or the clamping operation part two on which the locking release structure is set during clamping action.

[0008] Furthermore, the position where the force is applied to the lock-releasing structure is close to the position where the force is applied to the clamping operation part one or the clamping operation part two where the lock-releasing structure is set, so as to ensure that the coordination relationship of different fingers can be adjusted by a single hand, and that force is applied to the clamping operation part one, the clamping operation part two and the lock-releasing structure at the same time, so as to ultimately ensure that the clamping action of applying force to the clamping operation part one and the clamping operation part two is completed, and the adjustment action when pressure increase is required and the adjustment action when the entire instrument is removed is completed.

[0009] Note: The initial state is the open state where the two clamping units are away from each other. Restoring the initial state is to restore from the clamping state to the open state. In the specific scenario, when the hemostatic device needs to be removed from the hemostatic site, the lock needs to be released to restore. How to effectively set up the instant locking structure and the locking contact structure to ensure that the direction of force applied to the lock release structure when unlocking is the same as or opposite to the direction of force applied to the clamping operation part one or the clamping operation part two of the lock release structure during the clamping action; and the force application position of the lock release structure is close to the force application position of the clamping operation part one or the clamping operation part two of the lock release structure, is the core issue of completing the task of single-handed operation. The following technical features are set to solve the above problems.

[0010] The instant lock structure includes: A long through hole is provided on the first clamping operation part; The arc-shaped rack is fixedly arranged inside the second clamping operation part and extends toward the first clamping operation part; the center of the arc-shaped rack is on the rotating shaft on which the first clamping unit and the second clamping unit rotate; during the clamping operation, the arc-shaped rack passes through the long through hole and moves. The elastic locking structure includes 1 to 5 groups of teeth that mesh with the arc-shaped rack to achieve position locking; in a non-external force control state, when the teeth of the elastic locking structure are in a clamping action in which the clamping operation part 1 and the clamping operation part 2 are close to each other, the teeth of the elastic locking structure mesh with the teeth of the arc-shaped rack; The lock release structure controls the position change of the elastic locking structure, so that the teeth of the elastic locking structure and the teeth of the arc-shaped rack are switched between an engaged locking state and a non-engaged locking state.

[0011] By setting the center of the arc-shaped rack on the rotating shaft, it can be ensured that the positions of the arc-shaped rack and the long through-hole do not change, and thus the elastic locking structure and the locking contact structure are relatively fixed; the elastic locking structure with teeth meshing with the arc-shaped rack can well achieve instant locking, and the teeth of the arc-shaped rack are inclined toward the second clamping operation part. This arrangement ensures that it can rotate in the direction in which the two clamping operation parts approach each other, and immediately lock the position relationship after stopping the force when the appropriate position is reached.

[0012] Furthermore, the distance between the upper side surface of the elongated through hole and the end of the clamping operation part away from the rotating shaft is greater than 8 mm; this arrangement 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 position of the fingers, and the operating force will not change too much due to the shortening of the force arm.

[0013] Furthermore, the lock release structure includes an outer hole portion that is inclined and protrudes outside the long through hole, and also includes a second portion that abuts against the elastic locking structure or is directly connected to the elastic locking structure. The portion with teeth of the elastic locking structure is unlocked by rotating; the outer hole portion is connected to the second portion, and the outer hole portion is controlled to enter the long through hole and move together with the second portion, driving the portion with teeth of the elastic locking structure to rotate, and releasing the teeth of the elastic locking structure from meshing with the teeth of the arc-shaped rack. In this way, it can be ensured that the lock release structure is outside the long through hole and moves along the first portion close to the clamping operation portion to release the lock.

[0014] Furthermore, an elastic locking structure is arranged on the clamping operation part, including an elastic reset structure, an engaging structure and a second rotating shaft. The engaging structure is provided with teeth that engage with the arc-shaped rack to achieve position locking. The second rotating shaft is arranged in the elongated through hole. The engaging structure is entirely or partially arranged in the elongated through hole, and the engaging structure rotates through the rotating shaft. In the absence of external force, the elastic reset structure maintains the contact between the engaging structure and the arc-shaped rack; the rotating shaft is perpendicular to the long side wall of the elongated through hole.

[0015] Furthermore, the elastic reset structure has one end as a fixed end and the other end as an abutting end, the fixed end portion is fixedly arranged on the clamping operation portion, and the abutting end portion abuts on the meshing structure; except for the fixed end portion, the other portions are freely arranged in the long through hole. With this arrangement, most of the structure can be accommodated in the long through hole, effectively saving the arrangement space.

[0016] Furthermore, the elastic reset structure is a metal elastic sheet structure, which includes a guide portion, an abutment portion, and the guide portion and the abutment portion are connected by a bent portion, wherein the guide portion is fixed at the upper edge of the long through hole; the teeth and the abutment portion of the meshing structure are arranged on both sides of the second rotating shaft. Through this arrangement, the elastic sheet can be easily fixed on the clamping operation part 1, with a good fixing effect, ensuring the provision of effective elastic force, and the setting of the bent portion can further increase the elastic buffering effect during the operation process, avoiding damage to the elastic structure caused by direct abutment.

[0017] Furthermore, the meshing structure extends away from the arc-shaped rack and extends to the outside of the long through hole to form a lock release structure; the meshing structure and the lock release structure are integrally connected to form a rotating plate that can rotate along the rotation axis in the long through hole. This arrangement can completely ensure that the force direction of the lock release is the same as or opposite to the force direction during the clamping action.

[0018] Alternatively, a locking release structure is provided on the clamping operation part 1 on the opposite side of the elastic reset structure, and the locking release structure includes an elastic pressing piece obliquely arranged on the outside of the long through hole and an abutting release structure connected to the elastic pressing piece, the abutting release structure abuts on the meshing structure, one end of the elastic pressing piece is fixed on the clamping operation part 1, and the other end is connected to the abutting release structure as a whole. By pressing the elastic reset structure toward the clamping operation part 1, the meshing structure is disengaged from the arc-shaped rack.

[0019] Furthermore, on the basis of ensuring the effective rotation of the clamping operation part 1 and the clamping operation part 2, the arc-shaped rack is arranged as close as possible to the inner side of the clamping operation part 1 of the rotating shaft 1. The length requirement of the overall clamping operation part 1 ensures that the maximum opening distance is within the range of distance controllable by one-hand operation.

[0020] Furthermore, the meshing structure includes two sections arranged at an angle, namely, a first section structure for setting teeth and a second section structure for connecting the locking release structure; the rotating shaft or rotating shaft hole on the meshing structure is arranged at the connection position of the two sections, and the distance from the edge position is less than 5mm; and the first section structure for setting teeth extends to the outside of the long through hole, and the second section structure also partially extends to the outside of the long through hole; the locking release structure is selected by extending the structure of the meshing structure. This setting can effectively ensure the stability of the structure itself, provide space for the setting of multiple teeth, and can also effectively penetrate the meshing effect to ensure an effective meshing locking state. In addition, by introducing both sections of the structure to the outside of the long through hole, the length requirement of the meshing structure can be shortened as a whole, thereby shortening the overall length of the clamping operation part as a whole, thereby reducing the maximum operating distance between the clamping operation part 1 and the clamping operation part 2, and reducing the difficulty of operation. Further, in order to improve the locking effect after the meshing structure is engaged with the arc rack, 3-5 groups of teeth are arranged on the meshing structure.

[0021] Technical Effects By initially setting the clamping unit 1 and the clamping unit 2 in the open state, the purpose of conveniently setting the hemostatic device to the bleeding position can be achieved.

[0022] By setting an instant locking structure and a lock release structure; external force controls the lock release structure to adjust the state of the instant locking structure, release the position lock of the clamping operation part 1 and the clamping operation part 2 by the instant locking structure, and the force direction applied to the lock release structure during unlocking is the same as or opposite to the force direction applied to the clamping operation part 1 or the clamping operation part 2 of the lock release structure during clamping; and the force application position applied to the lock release structure is close to the force application position of the clamping operation part 1 or the clamping operation part 2 of the lock release structure, so that the coordination relationship of different fingers can be adjusted by a single hand, and the clamping operation part 1, the clamping operation part 2 and the lock release structure can be applied at the same time, so as to finally ensure that the clamping action and the adjustment action when the pressure increase and the removal of the entire instrument are completed. The whole operation process is simple and convenient.

[0023] By setting a long strip through hole, and setting the arc-shaped rack and elastic locking structure of the instant locking structure, and the locking release structure around the long strip through hole, the arc-shaped rack passes through the long strip through hole, and the meshing and locking of the arc-shaped rack is completed in the long strip through hole; the meshing and locking are released by the locking release structure set next to the hole to perform pressure reduction adjustment; finally, all structures required for clamping operation and locking release action can be achieved by adjusting the fingers of one hand.

[0024] On the basis of ensuring the effective rotation of the clamping operation part one and the clamping operation part two, the arc-shaped rack is arranged as close as possible to the inner side of the clamping operation part one of the rotating shaft one, so that the length of the arc-shaped rack and the length requirement of the entire clamping operation part one can be effectively reduced, thereby ensuring that the maximum opening distance is within the distance range that can be controlled by one-handed operation.

[0025] By effectively setting the shape of the meshing structure of the elastic locking structure, the meshing locking and rotation unlocking action requirements can be met with a shorter length, and the length of the clamping operation part can be shortened to a certain extent, thereby better ensuring one-handed operation.

The force direction applied to the lock release structure during unlocking is the same as or opposite to the force direction applied to the clamping operation part 11 or the clamping operation part 2 12 on which the lock release structure is set during clamping action; Furthermore, the position where the force is applied to the lock-releasing structure is close to the position where the force is applied to the clamping operation part 11 or the clamping operation part 12 on which the lock-releasing structure is set, so as to ensure that the coordination relationship of different fingers can be adjusted by a single hand, and that force is applied to the clamping operation part 11, the clamping operation part 12 and the lock-releasing structure at the same time, so as to ultimately ensure that the clamping action of applying force to the clamping operation part 11 and the clamping operation part 12 is completed, and the adjustment action when pressure increase is required and the adjustment action when the entire instrument is removed is completed.

[0028] The specific implementation method of the instant locking structure is that the instant locking structure includes: A long through hole 41 is provided on the clamping operation part 11; The arc-shaped rack 42 is fixedly arranged inside the clamping operation part 2 12 and extends toward the clamping operation part 1 11; the center of the arc-shaped rack 42 is on the rotating shaft of the clamping unit 1 and the clamping unit 2; during the clamping operation, the arc-shaped rack 42 passes through the long through hole 41 and moves; The elastic locking structure includes 1-5 groups of teeth 4321 that mesh with the arc-shaped rack 42 to achieve position locking; in a non-external force control state, when the clamping operation part 11 and the clamping operation part 2 12 are in a clamping action, the teeth 4321 of the elastic locking structure mesh with the teeth 4321 of the arc-shaped rack 42; The lock release structure is used to control the position change of the elastic locking structure, so that the teeth 4321 of the elastic locking structure and the teeth 4321 of the arc-shaped rack 42 are switched between an engaged locked state and a non-engaged locked state.

[0029] By setting the center of the arc-shaped rack 42 on the rotating shaft, it can be ensured that the positions of the arc-shaped rack 42 and the long through hole 41 do not change, and then the elastic locking structure and the locking contact structure are relatively fixed; the elastic locking structure with teeth 4321 meshing with the arc-shaped rack 42 can well achieve instant locking, and the teeth 4321 of the arc-shaped rack 42 are inclined toward the clamping operation part 12. This setting ensures that it can rotate in the direction of the two clamping operation parts approaching each other, and immediately locks the position relationship after stopping the force when reaching the appropriate position.

[0030] A more preferred embodiment is that the distance between the upper side surface of the elongated through hole and the end of the clamping operation part away from the rotating shaft is greater than 8 mm; this arrangement 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, and the operating force will not change too much due to the shortening of the force arm.

[0032] A more preferred embodiment is that the elastic locking structure is arranged on the clamping operation part 11, including an elastic reset structure 431, an engaging structure 432 and a second rotating shaft 433, the engaging structure 432 is provided with teeth 4321 which engage with the arc-shaped rack 42 to achieve position locking, the second rotating shaft 433 is arranged in the elongated through hole, the engaging structure 432 is fully or partially arranged in the elongated through hole, and the engaging structure 432 rotates through the rotating shaft, and the elastic reset structure 431 maintains the contact between the engaging structure 432 and the arc-shaped rack 42 in the absence of external force; the rotating shaft is perpendicular to the long side wall of the elongated through hole 41.

[0033] A more preferred embodiment is that the elastic reset structure 431 has one end as a fixed end and the other end as an abutting end, the fixed end portion is fixedly arranged on the clamping operation portion, and the abutting end portion abuts on the meshing structure 432; except for the fixed end portion, the other portions of the elastic reset structure 431 are freely arranged beside or inside the long through hole 41; through this arrangement, most of the structure can be stored beside and inside the long through hole 41, effectively saving the setting space. Finally, the slot is arranged inside or beside the long through hole 41 near the top position of the clamping operation portion 11 to ensure the feasibility of one-handed operation.

[0034] A more preferred embodiment is that the elastic reset structure 431 is a metal elastic sheet structure, which includes a guide portion 4311 and an abutment portion 4313 extending axially along the long through hole 41, and the guide portion 4311 and the abutment portion 4313 are connected by a bent portion 4312; wherein the guide portion 4311 is fixed at the upper edge of the long through hole 41; the teeth 4321 and the abutment portion 4313 of the meshing structure 432 are arranged on both sides of the second rotating shaft 433. This arrangement can very conveniently fix the elastic sheet on the clamping operation portion 11, with a good fixing effect, ensuring that effective elastic force is provided, and the arrangement of the bent portion 4312 can further increase the elastic buffering effect during operation, avoiding damage to the elastic structure caused by direct abutment. A more preferred embodiment is that, with reference to Fig. 9 In order to provide elasticity to the elastic reset structure 431, two abutment portions 4313 are extended from the guide portion 4311; both are connected via the corresponding bending portion 4312.

[0035] A more preferred embodiment is to refer to Figure 2-4 The meshing structure 432 extends away from the arc-shaped rack 42 and extends to the outside of the long through hole 41 to form a lock release structure; the meshing structure 432 is integrally connected with the lock release structure, and the whole is constructed into a rotating plate that can rotate along the rotation axis in the long through hole 41. This arrangement can completely ensure that the force direction of the lock release is the same as or opposite to the force direction during the clamping action.

[0036] In a more preferred embodiment, the lock release structure further includes a pressing plate 51 arranged perpendicular to the rotating plate, and the pressing plate 51 is notch-shaped or elliptical. This arrangement increases the comfort level of pressing to unlock.

[0037] Alternatively, refer to Figure 5-6 A locking release structure is provided on the clamping operation part 11 on the opposite side of the elastic reset structure 431. The locking release structure includes an elastic pressing piece 52 obliquely arranged on the outside of the long through hole 41 and a contact release structure 53 connected with the elastic pressing. The contact release structure 53 contacts the meshing structure 432. One end of the elastic pressing piece 52 is fixed on the clamping operation part 11, and the other end is connected to the contact release structure 53. By pressing the elastic reset structure 431 toward the clamping operation part 11, the meshing structure 432 is disengaged from the arc-shaped rack 42.

[0038] A more preferred embodiment is to set the arc-shaped rack 42 as close to the inner side of the clamping operation part 11 as possible to the rotation axis 1 on the basis of ensuring the effective rotation of the clamping operation part 11 and the clamping operation part 2 12. The length requirement of the entire clamping operation part 11 ensures that the maximum opening distance is within the range of distance that can be controlled by one-hand operation.

[0039] A more preferred embodiment is to refer to Figure 8-9 ; A rectangular opening is set at one end of each clamping operation part close to the rotating shaft one, which is defined as rectangular opening one 61 and rectangular opening two 62. The width of rectangular opening one 61 is larger than that of rectangular opening two 62, and the width of rectangular opening one 61 is larger than the overall width of the clamping operation part where rectangular opening two 62 is set. This setting is used to facilitate the cross-combination of two clamping operation parts through rectangular opening one 61; rotating shaft one passes through rectangular opening one 61 and rectangular opening two 62; a reset spring 31 is set in rectangular opening two 62.

[0040] A more preferred embodiment is that the arc-shaped tooth plate is arranged on the clamping operation part where the rectangular opening 1 61 is located, and the arc-shaped tooth plate is arranged above the rectangular opening 1 61, and the distance does not exceed 5mm; the long through hole 41 is arranged on the clamping operation part where the rectangular opening 2 62 of the rectangular plate is located. This arrangement can reduce the length of the entire clamping operation part, and avoid that some operators with small palms cannot complete the operation due to the large end distance. It can also maintain the stability of the clamping hemostatic device structure and avoid the interval between the long through hole 41 and the rectangular opening 2 62 being too small.

[0041] A more preferred embodiment is reference Figure 7-10 The meshing structure 432 includes two parts arranged at an angle, namely a first section structure 4322 with teeth 4321 and a second section structure 4323 connected to the lock release structure; the shaft or shaft hole on the meshing structure 432 is arranged at the connection position of the two sections, and the distance from the edge position is less than 5mm; and the first section structure 4322 with teeth 4321 extends to the outside of the long through hole 41, and the second section structure 4323 also partially extends to the outside of the long through hole 41; the lock release structure is selected by extending the meshing structure 432; specifically, a shaft is arranged on the second section structure 4323 to connect with it. The vertical pressing plate 51, the part where the second section structure 4323 is connected to the pressing structure and the pressing structure constitute a complete locking release structure; this arrangement can effectively ensure the stability of the structure itself, provide space for the arrangement of multiple teeth 4321, and can also effectively penetrate the meshing effect to ensure an effective meshing locking state. In addition, by introducing both sections of the structure into the outside of the long through hole 41, the required length of the meshing structure 432 can be shortened as a whole, thereby shortening the overall length of the clamping operation part as a whole, thereby reducing the maximum operating distance between the clamping operation part 11 and the clamping operation part 2 12, and reducing the difficulty of operation. A more preferred embodiment is that in order to improve the locking effect after the meshing structure 432 is meshed with the arc-shaped rack 42, 3-5 groups of teeth 4321 are arranged on the meshing structure 432.

[0042] A more preferred embodiment is to refer to Figure 11-13; The clamping hemostatic part 21 and the clamping hemostatic part are curved structures; an effective clamping space is constructed by the curved panel 72, which can also improve the clamping effect; the clamping operation part 11 and the clamping operation part 2 12 are inclined handle-type structures arranged in the middle position of the clamping hemostatic part 21 and the clamping hemostatic part 22; by operating the inclined handle, the operation is made more convenient.

[0044] A more preferred embodiment is that the ends of the clamping hemostatic part 1 21 and the clamping hemostatic part 2 22 are provided with piercing needles 71 for facilitating piercing the skin and improving clamping stability. The piercing needles 71 on the clamping hemostatic part 1 21 and the clamping hemostatic part 2 are staggered. This arrangement facilitates uniform and stable grasping of the skin.

[0045] A more preferred embodiment is that, except for the different setting positions of the puncture needle 71, the setting methods of the clamping hemostatic part 21 and the clamping hemostatic part 22 are the same. Taking the clamping hemostatic part 21 as an example for structural description, the clamping hemostatic part 21 includes a curved panel 72 connected to the clamping operation part 11, and also includes a plurality of spacer plates 73 arranged in parallel along the edge of the curved panel 72, the first end of which is connected to the curved panel 72 and the second end of which is connected to the puncture needle 71.

[0046] In a more preferred embodiment, the partition plate 73 continues to extend along the curved direction of the curved plate 72 connected thereto, and the puncture needle 71 is a straight short needle, which is arranged along the tangent direction of the position of the puncture needle 71 arranged along the partition plate 73. This arrangement can ensure that the puncture needle 71 can effectively puncture the skin.

[0047] A more preferred embodiment is that the puncture needle 71 is set in the middle position of the setting plane of the spacer plate 73, and the diameter of the puncture needle 71 is less than or equal to the diameter of the inscribed circle in the setting plane. This setting can prevent the spacer plate 73 from piercing the skin together with the puncture needle 71, so that the puncture needle 71 only has the effect of grasping and stabilizing, and will not cause excessive damage to the skin.

[0048] 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 the human body, the length of the puncture needle is less than 2 mm.

[0049] In a more preferred embodiment, the first end of the spacer 73 is an end where the puncture needle 71 is arranged, and the cross section of the first end of the spacer 73 is arranged in a trapezoidal shape, and the trapezoidal side close to the first end is the short side, and the trapezoidal side away from the first end is the long side. This arrangement ensures that although the spacer 73 cannot be pierced into the skin, the gradually changing size can ensure that the first end of the spacer 73 is deeply sunken into the skin and that the puncture needle 71 pierces the skin to form a gripping force.

[0050] A more preferred embodiment is to refer to Fig.14 In order to effectively protect the puncture needle 71 of the clamping hemostatic device before use, to avoid contamination and accidental injury before use, a needle body protector 74 is provided, and the needle body protector 74 corresponds to the hole for accommodating the needle body to extend into; the first end of the needle body protector 74 is a straight horizontal surface, and the second end of the needle body protector 74 is matched to the area of ​​the adjacent partition plate 73 with a trapezoidal cross section. This arrangement can effectively protect the needle body.

The appropriate balloon can also be selected according to the size of the bleeding area and temporarily set on the inner side of the clamping hemostatic part to complete hemostasis. Because the hemostatic balloon is an existing technology for long bones, the balloon is not shown in the figure.
