Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically relates to a hemostatic compression device for cardiovascular interventional surgery. Background Art

[0002] Cardiovascular interventional surgery has become an important means for the treatment of cardiovascular diseases due to its advantages such as minimal invasiveness and rapid recovery. After the surgery, hemostasis treatment at the puncture site is a key link in postoperative recovery. Traditional hemostasis methods, such as manual finger pressure, not only consume a large amount of time and energy of medical staff, but also it is difficult to accurately control the pressure magnitude and duration, and problems such as insufficient hemostasis leading to bleeding and hematoma, or excessive pressure causing local tissue ischemia and necrosis are likely to occur.

[0003] Currently, most of the clinically used hemostatic compression devices adopt a design that starts compression immediately after positioning. When the existing compression device is aligned with the wound for positioning, the compression module will contact the interventional catheter and the wound, applying pressure in advance. This will cause the compression device to contact the catheter prematurely, increase the resistance during catheter extraction, cause the catheter to deform, and advance compression of the wound will block local blood flow, cause tissue ischemia, increase the risk of subcutaneous ecchymosis and hematoma formation, and prolong the patient's recovery time.

[0004] Therefore, a hemostatic compression device for cardiovascular interventional surgery is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a hemostatic compression device for cardiovascular interventional surgery to solve the problem that when the existing compression device is aligned with the wound for positioning, the compression module will contact the interventional catheter and the wound, applying pressure in advance, which causes the compression device to contact the catheter prematurely as mentioned in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A hemostatic compressing device for cardiovascular intervention surgery, including a device support. A compressing mechanism for compressing the wound is provided at the front end of the device support. The compressing mechanism includes a movable chamber. A pressing plate is movably connected inside the movable chamber. A first magnet is connected at the bottom of the pressing plate. A sliding rod is fixedly connected to one side of the pressing plate. An outer shell is fixedly connected to the sliding rod. An electric motor is placed inside the outer shell. The first magnet is fixedly connected to the output shaft of the electric motor. A start switch of the electric motor is provided on the side surface of the outer shell. A chute matching the sliding rod is opened on the side surface of the device support. Two movable rods are movably connected inside the pressing plate. The two movable rods are fixedly connected by a first spring. A buckle is also movably connected to the side surface of the movable rod. A torsion spring is provided at the rotational connection of the movable rod and the buckle. A limiting tenon is opened on the inner wall of the movable chamber. The limiting tenon matches the buckle. Unlocking plates are movably connected to both sides of the pressing plate. The pressing plate and the unlocking plates are fixedly connected by a second spring. Two inserting tenons are fixedly connected to the side surface of the unlocking plate. Slots matching the inserting tenons are opened at both ends of the two movable rods. So that when the unlocking plates on both sides of the pressing plate are pressed simultaneously, the inserting tenons move into the slots, driving the two movable rods to move into the pressing plate, so that the buckle is disengaged from the restriction of the limiting tenon to unlock. A passive plate is movably connected to the bottom of the movable chamber. A second magnet that repels the first magnet is fixedly connected to the top of the passive plate. Two positioning blocks are fixedly connected to the bottom of the passive plate. Compressing blocks are movably connected to both positioning blocks. Magnets that attract each other are fixedly connected to the opposite side surfaces of the two compressing blocks; A tube extraction mechanism for assisting in tube extraction is provided at the bottom of the device support. The tube extraction mechanism includes a tube clamp and a track fixed to the bottom of the device support. The tube clamp slides on the track. A fixed block is fixedly connected to the tube clamp. A long rod is fixedly connected to one side of the fixed block. A tube clamping member is sleeved on the outer side of the long rod. A limiting buckle for restricting the movement of the two compressing blocks is fixedly connected to one end of the tube clamping member. The limiting buckle matches the groove in the middle of the initial positions of the two compressing blocks. So that the tube clamp is clamped on the pipeline. When extracting the tube, the tube clamp drives the connecting rod to move through the fixed block. At the same time, the connecting rod drives the limiting buckle to move through the tube clamping member. So that the limiting buckle is disengaged from the middle position of the two compressing blocks. When the pipeline is extracted, the two compressing blocks are instantaneously adsorbed together to compress the wound.

[0007] Preferably: A buffer layer for fitting the skin is fixedly connected to the bottom of the compressing block. A hemostatic dressing is applied to the bottom of the buffer layer. Anti-slip friction lines are opened on the side surface of the unlocking plate.

[0008] Preferably: a fixing mechanism for fixing is also provided on the side of the equipment bracket, and the fixing mechanism includes a fixing seat fixed on both sides of the equipment bracket, a round rod is fixedly connected to the fixing seat, and the round rod is movably connected to a meniscus through a cable tie, and a rotating rod is fixedly connected to one end of the cable tie, and rotating grooves matching the rotating rod are opened on both sides of the meniscus.

[0009] Preferably: the end of the equipment bracket is movably connected with a limiting mechanism for limiting, the limiting mechanism includes a ball slot rod rotatably connected to the end of the equipment bracket, the bottom of the ball slot rod is movably connected with a ball joint rod, the bottom of the ball joint rod is fixedly connected with a telescopic sleeve plate, and the rotating connection between the ball slot rod and the equipment bracket is movably connected with a tightening knob for locking.

[0010] Preferably: a positioning mechanism for auxiliary positioning is also provided at the front end of the equipment bracket, and the positioning mechanism includes shaft seats fixedly connected to both ends of the equipment bracket, and both shaft seats are movably connected with straight rods, and the straight rods are fixedly connected with arc plates for positioning.

[0011] Preferably, a Velcro strip for fixing is fixedly connected to the cable tie, and a soft rubber layer is fixedly connected to the inner side of the meniscus, and a plurality of small holes for ventilation are provided on the meniscus.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses the mutual repulsion between the magnet 1 at the bottom of the pressing plate and the magnet 2 at the top of the passive plate, so that the passive plate drives the compression block to slowly approach the wound, thereby avoiding the impact force of the traditional compression method. The magnets on the opposite sides of the two compression blocks can make them closely adsorb after being aligned with the wound, and cooperate with the bottom buffer layer and the hemostatic dressing to achieve uniform and stable pressure application. The cooperation of the movable rod, the buckle and the limit stopper can lock the position of the pressing plate. Through the structural design of the unlocking plate, the plug stopper and the slot, the lock can be quickly released to adjust the compression force, meet the hemostasis needs of different patients, and reduce complications such as bleeding, hematoma or tissue ischemia caused by improper pressure. The present invention prevents the compression block from closing prematurely by inserting the limit buckle into the groove of the initial position of the compression block, thereby preventing the compression block from contacting the pipe during positioning to increase the resistance to tube removal or block the blood flow. When the pipe is removed, the pipe clamp slides along the track to drive the limit buckle to disengage from the groove. At the moment the pipe is removed, the two compression blocks quickly absorb and compress the wound under the attraction of the magnet, thereby achieving seamless connection between tube removal and hemostasis. While reducing the number of operating steps, the delay of manually adjusting the compressor after tube removal in the traditional process is avoided, the risk of subcutaneous ecchymosis and hematoma formation is reduced, and the hemostasis efficiency and safety are improved. In the present invention, the cable tie and the magic tape of the fixing mechanism can be flexibly adjusted according to the thickness of the patient's limb. The soft glue layer on the inner side of the meniscus enhances the degree of fit, and the ventilation holes improve the wearing comfort, ensuring the stable fixation of the device. The ball groove rod, the ball joint rod and the telescopic sleeve plate of the limiting mechanism can be adjusted at multiple angles. After the tightening knob is locked, the device bracket can adapt to the support requirements of different wound positions. The arc plate of the positioning mechanism rotates around the shaft seat through the straight rod, and can fit the skin around the wound to form an arc-shaped positioning reference, assisting medical staff to quickly align the puncture point and avoiding poor hemostasis effect caused by deviation of the compression position. The whole set of structural design forms a complete system from fixation, support to precise positioning, improving the operation convenience and treatment reliability.

Detailed implementation manners

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0016] Please refer to Figures 1 to 8 , the present invention provides a technical solution for a hemostatic compressing device for cardiovascular interventional surgery: A hemostatic compressing device for cardiovascular interventional surgery, including a device bracket 1. A compressing mechanism 4 for compressing the wound is provided at the front end of the device bracket 1. The compressing mechanism 4 includes a movable bin 41. A pressing plate 43 is movably connected inside the movable bin 41. A first magnet 44 is connected to the bottom of the pressing plate 43. A sliding rod 417 is fixedly connected to one side of the pressing plate 43. An outer shell 416 is fixedly connected to the sliding rod 417. An electric motor 418 is placed inside the outer shell 416. The first magnet 44 is fixedly connected to the output shaft of the electric motor 418. A start switch of the electric motor 418 is provided on the side surface of the outer shell 416. A chute 419 matching the sliding rod 417 is opened on the side surface of the device bracket 1. Two movable rods 46 are movably connected inside the pressing plate 43. The two movable rods 46 are fixedly connected by a first spring 48. A buckle 47 is also movably connected to the side surface of the movable rod 46. A torsion spring is provided at the rotational connection of the movable rod 46 and the buckle 47. A limiting tenon 42 is opened on the inner wall of the movable bin 41. The limiting tenon 42 matches the buckle 47. Unlocking plates 49 are movably connected to both sides of the pressing plate 43. The pressing plate 43 and the unlocking plates 49 are fixedly connected by a second spring 410. Two insertion tenons 411 are fixedly connected to the side surface of the unlocking plate 49. Slots 412 matching the insertion tenons 411 are opened at both ends of the two movable rods 46. When the unlocking plates 49 on both sides of the pressing plate 43 are pressed simultaneously, the insertion tenons 411 move into the slots 412, driving the two movable rods 46 to move into the pressing plate 43, so that the buckle 47 is disengaged from the restriction of the limiting tenon 42 for unlocking. A passive plate 413 is movably connected to the bottom of the movable bin 41. A second magnet 45 that repels the first magnet 44 is fixedly connected to the top of the passive plate 413. Two positioning blocks 414 are fixedly connected to the bottom of the passive plate 413. Compressing blocks 415 are movably connected to both of the two positioning blocks 414. Magnets that attract each other are fixedly connected to the opposite side surfaces of the two compressing blocks 415. A buffer layer for attaching to the skin is fixedly connected to the bottom of the compressing block 415. A hemostatic dressing is applied to the bottom of the buffer layer. Anti-slip friction lines are opened on the side surface of the unlocking plate 49; During operation, when compression of the wound is required, medical staff press down on the pressing plate 43. Since the buckles 47 on both sides of the movable rod 46 match the limit pins 42 and a torsion spring is provided inside, the pressing plate 43 is fixed. At this time, the passive plate 413 moves downward under the repulsive force between the magnet one 44 and the magnet two 45, and drives the compression block 415 at the bottom closer to the wound. Since the magnets on the opposite sides of the two compression blocks 415 attract each other, when the compression block 415 contacts the skin and aligns with the wound, the two compression blocks 415 will tightly adsorb together, and uniform pressure is applied to the wound through the buffer layer and hemostatic dressing at the bottom to achieve hemostasis. When it is necessary to reduce the compression force or unlock the device, both hands simultaneously press the unlocking plates 49 on both sides of the pressing plate 43. The unlocking plates 49 move inward under the force of the spring two 410, and the insertion pins 411 on the side are inserted into the slots 412 at both ends of the movable rod 46, driving the two movable rods 46 to move into the pressing plate 43, causing the buckles 47 on the sides of the movable rod 46 to disengage from the limit pins 42 on the inner wall of the movable bin 41 and releasing the lock on the pressing plate 43. When compressing the patient's wound for a period of time, the start button on one side of the pressing housing 416 starts the electric motor 418. At this time, the electric motor 418 drives the magnet one 44 to rotate. Since the magnetic poles of the magnet one 44 and the magnet two 45 alternately attract or repel (at this time, the distance between the pressing plate 43 and the housing 416 is sufficient for the magnet one 44 to flip), an alternating compression is formed on the patient's wound. The "pumping effect" of the human muscle contraction on blood vessels is simulated by the periodic alternating pressure of the compression block 415, promoting the venous blood flow around the puncture point and reducing the risk of thrombosis caused by blood stasis. At the same time, the alternating compression avoids a single part from bearing high pressure for a long time, reducing complications such as skin pressure sores and nerve compression such as the ulnar nerve, especially suitable for obese or skin-sensitive patients.

[0017] As an embodiment of the present invention, as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, a tube extraction mechanism 6 for assisting in tube extraction is provided at the bottom of the device bracket 1. The tube extraction mechanism 6 includes a tube clamp 61 and a track 62 fixed to the bottom of the device bracket 1, and the tube clamp 61 slides on the track 62. A fixed block 63 is fixedly connected to the tube clamp 61. One side of the fixed block 63 is fixedly connected to a long rod 65. A tube clamping 66 is sleeved outside the long rod 65. One end of the tube clamping 66 is fixedly connected to a limit buckle 67 for restricting the movement of the two compression blocks 415, and the limit buckle 67 matches the groove in the middle of the initial positions of the two compression blocks 415, so that the tube clamp 61 is stuck on the pipeline. When extracting the tube, the tube clamp 61 drives the connecting rod 64 to move through the fixed block 63, and at the same time the connecting rod 64 drives the limit buckle 67 to move through the tube clamping 66, so that the limit buckle 67 disengages from the middle position of the two compression blocks 415, so that when the pipeline is extracted, the two compression blocks 415 are instantly adsorbed together to compress the wound; During operation, before tube extraction, the tube clamp 61 is clamped on the intervention pipeline, and the tube clamp 61 is located at the initial position of the track 62. At this time, the limit buckle 67 is snapped into the groove between the initial positions of the two pressing blocks 415, restricting the movement of the pressing blocks 415 to ensure that the pressing blocks 415 do not prematurely close and compress the pipeline during tube extraction. When extracting the tube, the medical staff pulls the pipeline outwards. The tube clamp 61 drives the long rod 65 to slide along the track 62 through the fixing block 63. The pipe clamping 66 on the outer side of the long rod 65 moves accordingly, driving the limit buckle 67 to disengage from the groove between the pressing blocks 415. When the pipeline is completely extracted, the two pressing blocks 415 that lose the restriction of the limit buckle 67 are instantly adsorbed together under the attraction of the magnets on the opposite sides, compressing and stopping bleeding at the wound, avoiding the problems of prematurely compressing the pipeline and the wound during the positioning of the traditional compressor. When the patient is in the supine position, the ball-slot rod 31 is adjusted to be perpendicular to the device bracket 1, and the track 62 is perpendicular to the direction of the wound. If the patient is in the left lateral position, after loosening the tightening knob 34, the ball-slot rod 31 is swung 45° to the left, and the ball-joint rod 32 is tilted synchronously, making the track 62 consistent with the anatomical direction of the wound to avoid angle deviation during tube extraction.

[0018] As an embodiment of the present invention, as Figure 1 、 Figure 2 and Figure 7 shown, a fixing mechanism 2 for fixing is further provided on the side surface of the device bracket 1. The fixing mechanism 2 includes fixing seats 21 fixed on both sides of the device bracket 1. A round rod 22 is fixedly connected to the fixing seat 21. The round rod 22 is movably connected with a semi-lunar plate 26 through a cable tie 23. One end of the cable tie 23 is fixedly connected with a rotating rod 24. Rotating grooves 25 matching the rotating rod 24 are provided on both sides of the semi-lunar plate 26. A magic tape for fixing is fixedly connected to the cable tie 23, and a soft glue layer is fixedly connected to the inner side of the semi-lunar plate 26. A plurality of small holes for ventilation are provided on the semi-lunar plate 26; During operation, the fixing mechanism 2 is used to fix the hemostatic compressor on the patient's limb. First, the device bracket 1 is placed near the patient's wound. The semi-lunar plate 26 is wound around the patient's limb (such as the wrist or thigh) through the cable tie 23. The magic tape on the cable tie 23 can adjust the tightness to ensure firm fixation, making the soft glue layer on the inner side of the semi-lunar plate 26 fit the limb skin. The plurality of ventilation small holes on the semi-lunar plate 26 can promote air circulation, reduce the stuffy feeling of the patient's limb, and improve comfort.

[0019] As an embodiment of the present invention, as Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown in the figure, a limiting mechanism 3 for limiting is movably connected to the end of the device support 1. The limiting mechanism 3 includes a ball groove rod 31 rotatably connected to the end of the device support 1. The bottom of the ball groove rod 31 is movably connected to a ball joint rod 32. The bottom of the ball joint rod 32 is fixedly connected to a telescopic sleeve plate 33. And a tightening knob 34 for locking is movably connected to the rotational connection between the ball groove rod 31 and the device support 1; During operation, the limiting mechanism 3 is used to adjust the position and angle of the device support 1 to adapt to the wound positions of different patients. Loosen the tightening knob 34, and the ball groove rod 31 can rotate around the end of the device support 1. At the same time, the ball joint rod 32 can swing in multiple directions at the bottom of the ball groove rod 31. By adjusting the angles of the ball groove rod 31 and the ball joint rod 32, the telescopic sleeve plate 33 is brought into contact with the patient's limb or the bed surface to play a supporting and limiting role. After adjusting to the appropriate position, tighten the tightening knob 34 to fix the rotational connection of the ball groove rod 31 and ensure the stability of the device support 1 to avoid displacement during the compression process.

[0020] As an embodiment of the present invention, as Figure 2 、 Figure 3 and Figure 7 shown in the figure, a positioning mechanism 5 for auxiliary positioning is further provided at the front end of the device support 1. The positioning mechanism 5 includes shaft seats 53 fixedly connected to both ends of the device support 1. A straight rod 52 is movably connected to each of the two shaft seats 53. An arc plate 51 for positioning is fixedly connected to the straight rod 52; During operation, the positioning mechanism 5 is used to assist medical staff in accurately aligning the wound. Rotate the straight rod 52 to make the straight rod 52 rotate around the shaft seat 53 and adjust the position of the arc plate 51. Fit the arc plate 51 to the skin around the patient's wound. Position the wound through the arc-shaped structure of the arc plate 51 to ensure that the compression block 415 of the compression mechanism 4 accurately aligns with the center of the wound. After the positioning is completed, the subsequent tube pulling and compression operations can be carried out through the compression mechanism 4 and the tube pulling mechanism 6, improving the accuracy and efficiency of the operation.

[0021] Working principle: During operation, first fix the device bracket 1 on the patient's limb through the cable tie 23 and the magic tape of the fixing mechanism 2. The inner soft rubber layer of the meniscus 26 fits the skin, and the breathable holes improve comfort. Then, rotate the arc plate 51 of the positioning mechanism 5 around the shaft seat 53 to assist in aligning the wound. Before tube extraction, clamp the tube clip 61 of the tube extraction mechanism 6 on the intervention pipeline, and snap the limit buckle 67 into the middle groove between the two pressing blocks 415 to restrict their movement. During tube extraction, pull the pipeline to make the tube clip 61 slide along the track 62, driving the limit buckle 67 to disengage from the groove. (The bottom of the device bracket 1 is fixedly connected to the track 62, and its end is rotatably connected to the device bracket 1 through the ball groove rod 31. The ball joint rod 32 at the bottom of the ball groove rod 31 can achieve 360° universal swing. With the length adjustment of the telescopic sleeve plate 33, the direction of the track 62 can be adjusted to align with the central axis of the wound according to the patient's body position (such as supine, lateral). During specific operation, the medical staff first loosen the tightening knob 34, adjust the inclination angle of the ball groove rod 31 and the swing angle of the ball joint rod 32 to direct the track 62 directly above the wound, and then tighten the tightening knob 34 to fix it, ensuring that the tube extraction direction is consistent with the guiding direction of the track 62.) After the pipeline is extracted, the two pressing blocks 415 are instantaneously adsorbed and pressed against the wound under the attraction of the magnets on the opposite sides. When the wound needs to be compressed, (the vertical compression force is driven by the repulsive force between magnet one 44 and magnet two 45 to generate the passive plate 413, and the horizontal adsorption force is provided by the magnets of the pressing blocks 415. The two are integrated into a composite pressure through the buffer layer), press down the pressing plate 43, and the buckles 47 on both sides of the movable rod 46 cooperate with the limit falcon 42 to fix the pressing plate 43. The repulsion between magnet one 44 and magnet two 45 causes the passive plate 413 to drive the pressing blocks 415 to approach the wound and adsorb. (The determination of the repulsive force between magnet one 44 and magnet two 45 conforms to the existing medical application scenarios, and can achieve the hemostasis effect, improve the operation safety and patient comfort. The type and spacing of the magnets are selected based on limited experiments without violating the principles and spirit of the present invention. For example, neodymium iron boron magnets), the buffer layer and the hemostatic dressing apply uniform pressure to stop bleeding. (The buffer layer is made of a medical-grade silicone material with a thickness of 2-3 mm (such as silicone rubber with a Shore hardness of 30A), and its elastic modulus is small, which can deform instantaneously when adsorbed by the magnet to disperse the local pressure), the magnets on the opposite sides of the two pressing blocks 415 are neodymium iron boron permanent magnets, and the pole spacing is designed to be 5-8 mm. The adsorption force meets the pressure range required for clinical hemostasis after being converted by the buffer layer), and then use the ball groove rod 31, ball joint rod 32 and telescopic sleeve plate 33 of the limiting mechanism 3 to adjust the position and angle of the device, and rotate the tightening knob 34 to fix it. When compressing the patient's wound for a period of time, press the start button on one side of the pressing shell 416 to start the electric motor 418. At this time, the electric motor 418 drives magnet one 44 to rotate. Due to the alternating attraction or repulsion of the magnetic poles of magnet one 44 and magnet two 45, an alternating press is formed on the patient's wound, and the "pumping effect" of the human muscle contraction on the blood vessels is simulated by the periodic alternating pressure of the pressing blocks 415, promoting the venous blood flow around the puncture point.Reduce the risk of thrombosis caused by blood stasis, and alternate compression to avoid a single part from being subjected to high pressure for a long time, reduce complications such as skin pressure sores and nerve compression such as the ulnar nerve. When unlocking, press the unlocking plate 49, insert the plug 411 into the slot 412 to drive the movable rod 46 to move, and the buckle 47 disengages from the limiter 42 to release the lock.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
