Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, in particular to the technical field of hemostatic devices, and specifically is an elastic clamping hemostatic device which pierces the skin at a limited interval. 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 treat bleeding on the body surface and limbs? The prior art has clamping hemostasis devices such as 202311766175.9, a pressure-adjustable dynamic gripping compression hemostasis device; this hemostasis device can achieve immediate wound closure through clamping, but how to achieve effective gripping after clamping and avoid slippage after clamping is a technical problem that this type of device needs to solve.
[0004] The utility model provides an elastic clamping hemostatic device which can penetrate into the skin at a limited interval. Utility Model Content
[0005] An elastic clamping hemostatic device for puncturing the skin at a limited interval comprises a clamping hemostatic part, a clamping operation part, and an elastic clamping connection part; the clamping hemostatic part comprises:
[0006] The wrapping part is divided into a wrapping part 1 and a wrapping part 2. The wrapping part 1 and the wrapping part 2 include a clamping hemostasis state and an open state. The clamping operation part controls the wrapping part to switch between the clamping hemostasis state and the open state. The clamping hemostasis state is a state of continuously clamping the bleeding part, and the open state is a setting state in which the clamping operation part controls the wrapping part to be opened.
[0007] The skin piercing part is divided into a skin piercing part one and a skin piercing part two, which are respectively connected to the wrapping part one and the wrapping part two; the skin piercing part one and the skin piercing part two are provided with piercing needles at intervals, and the interval distance between every two piercing needles on the same side is greater than or equal to 1 cm; the piercing needle is a conical piercing needle, and the diameter of the piercing needle at the maximum dimension is not greater than 4 mm.
[0008] The above-mentioned setting of the puncture needles can effectively ensure that the puncture needles arranged at intervals penetrate into the skin to ensure the stability of the clamping hemostasis after the clamping hemostasis structure is set. In addition, the setting method with an interval distance greater than or equal to 1 cm can more effectively avoid the risk of excessive damage to the skin or continuous wounds on the skin caused by too close spacing.
[0009] In the clamping hemostasis state, the puncture needles set at intervals pierce the patient's skin.
[0010] Preferably, the distance between the needle tips of every two puncture needles arranged on the same side is greater than or equal to 2 cm and less than or equal to 4 cm; such spacing distance setting is safer and more reliable.
[0011] Preferably, the length of the puncture needle is not more than 2 mm; preferably not more than 1 mm; a blocking ball with a diameter larger than the puncture needle is set between the puncture needle and the wrapping part, and the diameter of the blocking ball is not less than 1 cm. The setting of the puncture needle length can prevent the puncture needle from entering the dermis, reducing the risk of infection after skin damage caused by the setting of the puncture needle; in addition, the setting of the blocking ball can further prevent the puncture needle from piercing too deep, and the setting of the blocking ball can also block the wound formed by the puncture needle, effectively reducing the damage caused by the puncture needle piercing the skin and avoiding bleeding there.
[0012] Preferably, the central axis of the puncture needle passes through the center of the blocking ball, and the central axis of the puncture needle is in the same direction as the edge of the surrounding part. This arrangement can effectively ensure that the puncture needle punctures the skin effectively and smoothly, avoiding greater damage to the skin due to inconsistent directions.
[0013] Preferably, the puncture needles for piercing the skin part 1 and the skin part 2 are arranged alternately, a gap 1 is arranged between every two puncture needles on one side, a protruding structure is arranged between the two gaps, and each puncture needle is arranged on the protruding structure. The staggered arrangement can facilitate natural closure when not in use, and the surrounding part is preferably closed. In addition, the setting of the gap 1 can effectively avoid the obstruction and stop effect of the surrounding part, which causes the puncture needle to be unable to pierce the skin. The main principle is that if the puncture needle is directly set to the surrounding part, the edge of the surrounding part is a straight line, and the straight line contacts the skin uniformly as early as possible, and the skin will have a reverse push force on it, which will prevent the puncture needle from further extending, and the setting of the gap 1 can effectively avoid the above problem.
[0014] The protruding structure includes a trapezoidal part, which includes two sides of the obstruction ball that are inclined and symmetrically arranged on both sides of the obstruction ball, the edges of the obstruction side surfaces are attached to the spherical surface of the obstruction ball, and also include a rectangular part extending from the bottom of the two obstruction side surfaces. The obstruction side surfaces are tangent to the obstruction ball. The connection between the arc surface of the obstruction ball and the obstruction side surfaces can effectively ensure the insertion of the puncture needle and prevent the puncture needle from entering too deep, and can also protect the skin. The obstruction ball is supported by a trapezoidal structure, and the contact between the two obstruction side surfaces and the obstruction ball can further form a positive guide for the insertion of the puncture needle, ensuring that it can effectively penetrate into the skin.
[0015] The beneficial effects of the utility model are:
[0016] 1) By arranging the puncture needles at intervals and maintaining a relatively large distance, the stability of the clamping hemostasis action can be ensured by piercing the skin.
[0017] 2) The setting of the notch 1 can effectively avoid the resistance of the puncture needle to the puncture caused by the straight edge of the wrapping part.
[0018] 3) By dividing the protruding structure into a trapezoidal part for accommodating the blocking ball and a rectangular part, the setting of the notch and the guidance of the piercing action of the piercing needle can be guaranteed to the greatest extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] refer to Figure 1-2 , an elastic clamping hemostatic device for piercing the skin with a limited interval, comprising a clamping hemostatic part, a clamping operation part, and an elastic clamping connection part; the clamping operation part controls the opening and closing of the clamping hemostatic part, and when the distance of the clamping operation part decreases, the distance of the clamping hemostatic part increases; when the distance of the clamping operation part increases, the distance of the clamping hemostatic part decreases, and the hemostatic pressure increases; the clamping operation part comprises a clamping operation part 1 21 and a clamping operation part 22; the elastic clamping connection part is used to connect the clamping hemostatic part and the clamping operation part, and maintain the elastic force for the clamping hemostatic part to restore the clamping state;
[0031] The clamping hemostasis part includes:
[0032] refer to Figure 3-4 The wrapping part is divided into a wrapping part 11 and a wrapping part 12. The wrapping part 11 and the wrapping part 12 include a clamping hemostasis state and an open state. The clamping operation part controls the wrapping part to switch between the clamping hemostasis state and the open state. The clamping hemostasis state is a state of continuously clamping the bleeding part, and the open state is a setting state in which the clamping operation part controls the wrapping part to open;
[0033] The skin piercing part is divided into a skin piercing part one and a skin piercing part two, which are respectively connected to the wrapping part one 11 and the wrapping part two 12; the skin piercing part one and the skin piercing part two are provided with piercing needles 131 at intervals, and the interval distance between every two piercing needles 131 on the same side is greater than or equal to 1 cm; the piercing needles 131 are conical piercing needles 131, and the diameter of the piercing needles 131 at the maximum dimension is not greater than 4 mm. In the clamping hemostasis state, the piercing needles 131 arranged at intervals pierce the patient's skin.
[0034] The arrangement of the puncture needles 131 can effectively ensure that the puncture needles 131 arranged at intervals penetrate into the skin to ensure the stability of the clamping hemostasis structure after the clamping hemostasis structure is arranged. In addition, the arrangement method with an interval distance greater than or equal to 1 cm can more effectively avoid the risk of excessive damage to the skin or continuous wounds on the skin caused by too close spacing.
[0035] In a more specific implementation, the distance between the needle tips of every two puncture needles 131 arranged on the same side is greater than or equal to 2 cm and less than or equal to 4 cm; such spacing distance setting is safer and more reliable.
[0036] A more specific implementation method is to refer to Figure 5The overall length of the puncture needle 131 is not more than 4 mm. A blocking ball 132 having a larger diameter than the puncture needle 131 is arranged between the puncture needle 131 and the wrapping portion, and the diameter of the blocking ball 132 is not less than 1 cm. The setting of the blocking ball 132 can effectively prevent the puncture from being too deep, and the setting of the blocking ball 132 can also block the wound formed by the puncture needle 131, effectively reducing the damage caused by the puncture needle 131 piercing the skin and preventing bleeding there.
[0037] In a more specific embodiment, the central axis of the puncture needle 131 passes through the center of the blocking ball 132, and the central axis of the puncture needle 131 is in the same direction as the edge of the surrounding portion. This arrangement can effectively ensure that the puncture needle 131 punctures the skin effectively and smoothly, avoiding greater damage to the skin due to inconsistent directions.
[0038] A more specific implementation is that the puncture needles 131 that pierce the skin part 1 and the skin part 2 are arranged alternately, a notch 133 is arranged between every two puncture needles 131 on one side, a protruding structure is arranged between the two notches 133, and each puncture needle 131 is arranged on the protruding structure. The staggered arrangement can facilitate natural closure when not in use, and the surrounding part is better closed. In addition, the setting of the notch 133 can effectively avoid the obstruction and stop effect of the surrounding part, which causes the puncture needle 131 to be unable to pierce the skin. The main principle is that if the puncture needle 131 is directly set to the surrounding part, the edge of the surrounding part is a straight line, and the straight line is about to uniformly contact the skin, and the skin will have a reverse push force on it, which will prevent the puncture needle 131 from further extending, and the setting of the notch 133 can effectively avoid the above problem.
[0039] The protruding structure includes a trapezoidal portion 133, which includes an attachment side surface 1331 that is inclined on both sides and symmetrically arranged on both sides of the blocking ball 132, the edges of the attachment side surface 1331 are attached to the spherical surface of the blocking ball 132, and also includes a rectangular portion 134 extending from the bottom of the two attachment side surfaces 1331. The attachment side surface 1331 is tangent to the blocking ball 132. The connection between the arc surface of the blocking ball 132 and the attachment side surface 1331 can effectively ensure the insertion of the puncture needle 131, and prevent the puncture needle 131 from entering too deep, and can also protect the skin. The blocking ball 132 is supported by a trapezoidal structure, and the contact between the two attachment side surfaces 1331 and the blocking ball 132 can further form a positive guide for the insertion of the puncture needle 131, ensuring that it can effectively puncture the skin.
[0040] A more specific implementation is: the shape of the wrapping part is C-shaped, and a hollow hole is set in the middle of the wrapping part. This arrangement can better achieve wrapping-type gripping of damaged skin and ensure overall breathability.
[0041] A more specific implementation method is to refer to Figure 1 ,6-9; A new pressure regulating structure can also be provided. The pressure regulating structure is a rotatable regulating structure, which includes a single regulating straight rod 31. The first end of the regulating straight rod 31 is always combined with the clamping operating part 21 and can rotate variably relative to the clamping operating part 21; the second end is combined with the clamping operating part 22 when adjusting the pressure and can rotate variably relative to the clamping operating part 22 after the combination, and the angle rotation plane is parallel to the clamping rotation plane of the clamping operating part; the force at the contact point between the regulating straight rod 31 and the operating part 2 is the supporting force.
[0042] During the clamping operation, the second end of the adjusting straight rod 31 is rotated away from the clamping operation part without interfering with the operation; when adjusting the pressure, the angle between the first end of the adjusting straight rod 31 and the clamping operation part 21 is variable, and the position of the second end of the adjusting straight rod 31 and the clamping operation part 22 is relatively stable and the angle is variable. The distance between the adjusting straight rod 31 and the clamping operation part 21 and the clamping operation part 22 is adjusted, and the hemostatic pressure increases when the distance is increased, and the hemostatic pressure decreases when the distance is decreased; once the position and angle of the adjusting straight rod 31 and the clamping operation part 21 and the clamping operation part 22 are determined, they will no longer change, thereby achieving the purpose of maintaining a certain hemostatic pressure.
[0043] A more specific setting method of the adjustment straight rod 31 is that the first end of the adjustment straight rod 31 is set on the clamping operation part 21 and is rotatable relative to the clamping operation part 21; during the clamping operation, the second end is rotated away from the space between the clamping operation part 21 and the clamping operation part 22; when adjusting the pressure, the second end is set on the clamping operation part 22, and the distance between the clamping operation part 21 and the clamping operation part 22 of the adjustment straight rod 31 changes. After the pressure adjustment is completed, the distance between the clamping operation part 21 and the clamping operation part 22 remains unchanged; the first end of the adjustment straight rod 31 is the operating end.
[0044] A more preferred embodiment is to refer to Figure 7-8The rotatable adjustment structure includes an angle adjustment block 32 and an adjustment straight rod 31. The angle adjustment block 32 is arranged on the clamping operation part 21 and can rotate relative to the clamping operation part 21. The rotation plane is parallel to the clamping rotation plane of the clamping operation part. The adjustment straight rod 31 is arranged through the angle adjustment block 32, and the relative angle between the adjustment straight rod 31 and the angle adjustment block 32 remains unchanged, but the relative position can be adjusted. After the adjustment, the position of the adjustment straight rod 31 relative to the angle adjustment block 32 remains unchanged. A notch 33 for accommodating the angle adjustment block 32 is arranged on the clamping operation part 1, and the angle adjustment block 32 is rotatably combined with the side wall of the notch 33. A rotating small opening is arranged on the side wall of the notch 33, corresponding to a rotating short rod extending out of the outside of the angle adjustment block 32; the rotating small opening and the rotating short rod are located in the middle position of the notch 33. This arrangement can ensure the maximum selection angle, that is, the most stable setting state. A rounded corner is arranged above the angle adjustment block 32 to avoid damage to the operator during operation. More specifically, the second notch 33 is set in the middle of the clamping operation part. During operation, the thumb is set at the position of the second clamping operation part 22, and the index finger and the middle finger are respectively set on both sides of the notch 33 of the first clamping operation part 21; this method makes it convenient to operate, and the extended adjustment straight rod 31 can be extended from the gap between the index finger and the middle finger, and the operation will not be interfered with by the rotatable adjustment structure.
[0045] A more preferred embodiment is that the first end of the adjusting straight rod 31 is arranged in the angle adjustment block 32, and the angle adjustment block 32 is provided with an adjusting hole 321 for the first end of the adjusting straight rod 31 to pass through the pipe, and at least the first end of the adjusting straight rod 31 is provided with an adjusting section that cooperates with the adjusting hole 321 to achieve relative position adjustment, and the length of the adjusting section meets the pressure adjustment requirements. The adjusting hole 321 is selected as a threaded hole, and the adjusting section is a corresponding threaded section, and the distance between the adjusting straight rod 31 and the clamping operation part 1 21 and the clamping operation part 2 22 is changed by rotating; the adjusting section can extend to all areas except the second end of the adjusting straight rod 31; or a locking nut is arranged outside the adjusting hole 321, and the adjusting section is a cylindrical section that can be locked by the locking nut (not shown in the figure); by holding the clamping operation part 1 21, the nut is unfastened, and the adjusting straight rod 31 is pushed out with force, and the locking nut is controlled to lock the adjusting section after reaching a suitable pressure. A more preferred embodiment is that the second end of the adjusting straight rod 31 is provided with an anti-slipping part to prevent the adjusting straight rod 31 from slipping out of the adjusting hole 321. The anti-slip structure can be an extension of the threaded section, or when the threaded section does not extend to the second end of the adjusting straight rod 31, an anti-slip ring larger than the adjusting hole 321 is provided. By arranging the adjusting straight rod 31 in sections, the adjusting straight rod 31 can be rotated to the part without the threaded section during the clamping operation, so that the anti-slip structure of the adjusting straight rod 31 can easily contact the angle adjustment block 32, reducing the part protruding above the angle adjustment block 32, thereby reducing the difficulty of the clamping operation.
[0046] A more specific implementation is as follows: the instrument further includes a positioning structure, which is arranged on the second clamping operation part 22, and is used to maintain the adjustment straight rod 31 in the position of the clamping operation part during adjustment and ensure the angle adjustment of the contact position between the second end of the adjustment straight rod 31 and the second clamping operation part 22. A specific implementation is as follows: the positioning structure is a receiving groove arranged on the second clamping operation part 22; the second end of the adjustment straight rod 31 is arranged to enter the receiving groove to achieve position limitation but ensure angle change.
[0047] Specifically, refer to Figure 6 ; An angle adjustment block 32 is provided on the clamping operation part 1 21, and a threaded hole is provided on the angle adjustment block 32. The adjusting straight rod 31 is a threaded rod and is provided in the threaded hole. The first end of the threaded rod is an end cap provided on one side of the clamping operation part 1, and the second end of the threaded rod is a conical head 342. The receiving groove is a cylindrical through hole 341. The conical head 342 is provided in the through hole 341. When the distance between the clamping operation part 1 21 and the clamping operation part 2 is adjusted, the angle between the conical head 342 and the cylindrical hole changes. The receiving groove is a through hole 341 that penetrates the clamping operation part 2 22, and the insertion head is a conical head 342 that extends into the through hole 341. Different edge positions of the conical head 342 contact the outer edge position of the through hole 341. This arrangement can ensure the angle change between the position of the adjusting straight rod 31 and the through hole 341. The through hole 341 is a cylindrical hole, and the angle between the axis of the conical head 342 and the axis of the cylindrical hole changes during the pressure adjustment process. A more preferred embodiment is that the maximum diameter of the conical head 342 is consistent with the through hole 341, and the length of the conical head 342 is greater than or equal to the diameter of the through hole 341. The above arrangement can ensure that the through hole 341 provides an effective adjustment space for the angle change of the conical head 342 in the through hole 341, and the shorter the distance of the conical head 342 extending into the through hole 341, the larger the adjustable space.
[0048] Alternatively, refer to Fig. 9An angle adjustment block 32 is provided on the clamping operation part 1 21, a threaded hole is provided on the angle adjustment block 32, the adjustment straight rod 31 is a threaded rod and is provided in the threaded hole, the first end of the threaded rod is an end cap provided on one side of the clamping operation part 1 21, the second end of the threaded rod is provided with a ball head structure 351, the receiving groove is a ball socket 352, the ball head structure 351 is provided in the ball socket 352, when the distance between the clamping operation part 1 21 and the clamping operation part 2 22 is adjusted, the angle between the ball head structure 351 and the ball socket 352 changes. The receiving groove is the ball socket 352, the insertion head is the ball head structure 351, and a more preferred embodiment is that the ball socket 352 and the ball head structure 351 are provided with guide protrusions and guide grooves correspondingly, which are used to guide the ball head to rotate in a plane after being combined with the ball socket 352, and the above plane is parallel to the rotation plane of the clamping operation part to ensure the stability of the adjustment. The arrangement of the ball socket 352 and the ball head structure 351 and the corresponding guide protrusion and guide groove can ensure the safety and effectiveness during adjustment. Further, the ball socket 352 is provided with an anti-drop protrusion.
[0049] Alternatively, an angle adjustment block 32 is also provided on the second clamping operation part 22, the receiving groove is an adjustment hole 321 provided on the angle adjustment block 32, and the second end of the adjustment straight rod 31 is also provided with an adjustment section. The angle adjustment block 32 on the second clamping operation part 22 is provided in the same manner as the angle adjustment block 32 on the first clamping operation part 21. This is also a very effective setting method.
[0050] In a more preferred embodiment, when the hemostatic device is in a static state, two parallel extensions 36 are extended from the clamping operation part 1 21 and the clamping operation part 2 22, the angle adjustment block 32 is arranged on the extension 36 of the clamping operation part 1 21, and the receiving groove is arranged on the extension 36 of the clamping operation part 22.
