Abstract

The present invention provides a compression hemostasis device for arterial intervention surgery, comprising a base plate and a compression mechanism, wherein the compression mechanism comprises a compression column and a positioning mechanism. The first driving component is pre-adjusted to drive the mounting block to slide, and the sliding of the mounting block drives the stop block and the limit block to slide, so that the stop block and the limit block slide to the specified position. After the arterial sheath is removed, pressure is immediately applied to the top of the compression column to move the compression column downward, and the downward movement of the compression column drives the compression plate, the silicone pad and the clamping block to move downward, and the first spring is compressed and contracted. When the clamping block moves downward and is clamped between the limit block and the stop block, the compression column stops moving and is fixed. At this time, the compression plate and the silicone pad move downward to apply a preset pressure to the puncture point. The speed of applying pressure to the puncture point is increased by directly driving the compression plate to move, and the size of the pressure applied to the puncture point can be controlled by pre-adjusting the positions of the limit block and the stop block, thereby improving the practicality of the device.

Description

Technical Field

[0001] The present invention relates to the technical field of hemostatic devices, and in particular to a compression hemostatic device for arterial intervention surgery. Background Art

[0002] During arterial interventional surgery, the blood vessel wall will be damaged to a certain extent, resulting in bleeding. The main purpose of compression hemostasis is to apply pressure to the puncture point through physical means to close the blood vessel wall, thereby achieving the effect of hemostasis. This step is of great significance in preventing postoperative bleeding, hematoma formation, and reducing complications.

[0003] For example, the Chinese patent No. 201610969486.9 discloses an arterial compression hemostat, including a base, an elastomer and connecting belts connected to both ends of the base, a spinning structure is connected to the base, the spinning structure includes a screw and a nut threadedly connected to the screw, a blood pressure plate is integrally provided at the lower end of the screw, the spinning structure also includes a support plate, the support plate is arranged between the blood pressure plate and the nut and is sleeved on the screw, a through hole is opened on the base, the screw and the nut after threaded connection are both penetrated through the through hole and the support plate is fixedly connected to the base, a groove is opened at one end of the blood pressure plate opposite to the screw, and the elastomer is arranged in the groove.

[0004] Existing compression hemostasis devices for arterial interventional surgery mostly apply pressure to the puncture point by rotating the hemostasis plate. The amount of pressure applied to the puncture point is determined by the number of revolutions of the rotating part. However, in actual operation, the rotation-driven hemostasis plate is not only slow in applying pressure to the puncture point, but also inconvenient to control the amount of pressure applied to the puncture point. When the pressure is too high, it is easy to cause skin damage and affect blood circulation. When the pressure is too low, it cannot achieve the purpose of hemostasis, which reduces the practicality of the device. Therefore, in view of the above technical problems, a compression hemostasis device for arterial interventional surgery is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention proposes a compression hemostasis device for arterial interventional surgery, which is convenient for quickly applying pressure to the puncture point and for controlling the magnitude of the pressure applied to the puncture point, thereby improving the practicability of the device.

[0006] A compression hemostasis device for arterial intervention surgery, comprising: a base plate and a compression mechanism, wherein both ends of the base plate are connected with Velcro tapes, a mounting seat is provided at the top of the base plate, a through hole is provided at the top of the mounting seat vertically penetrating the mounting seat and the base plate, and the compression mechanism comprises:

[0007] A pressing column runs through the through hole, and a pressing plate is arranged at the bottom end, a silicone pad is arranged at the bottom end of the pressing plate, a first spring is sleeved on the pressing column, and two ends of the first spring respectively press against the top end of the mounting seat and the top end of the pressing column; and

[0008] The positioning mechanism comprises a mounting block, a limit block, a second spring, a card block, a first driving assembly and a second driving assembly; the mounting block can be slidably arranged in the mounting seat in a vertical direction, and a stop block is arranged at one end of the mounting seat close to the pressing column, the limit block can be slidably arranged at the top of the mounting block horizontally, the second spring connects the limit block and the mounting block, and is used to apply a thrust toward the pressing column to the limit block, the card block can be slidably arranged in the mounting seat in a vertical direction and is connected to the pressing column, and the card block can be slidably arranged between the limit block and the stop block, the first driving assembly is arranged on the mounting seat and connected to the mounting block, and is used to drive the mounting block to slide, and the second driving assembly is arranged on the mounting block and connected to the limit block, and is used to drive the limit block to slide to cancel the limit on the card block.

[0009] The beneficial effects of the above-mentioned compression hemostasis device for arterial intervention surgery are:

[0010] According to the amount of pressure applied to the puncture point, the mounting block is driven to slide by pre-adjusting the first driving component, and the sliding of the mounting block drives the stop block and the limit block to slide, so that the stop block and the limit block slide to the specified position. After the arterial sheath is removed, pressure is immediately applied to the top of the pressing column to move the pressing column downward. The downward movement of the pressing column drives the compression plate, the silicone pad and the card block to move downward, and the first spring is compressed and contracted. When the card block moves downward and is stuck between the limit block and the stop block, the pressing column stops moving and is fixed. At this time, the compression plate and the silicone pad move downward to apply a preset pressure to the puncture point. The speed of applying pressure to the puncture point is increased by directly driving the compression plate to move, and the amount of pressure applied to the puncture point can be controlled by pre-adjusting the positions of the limit block and the stop block, thereby improving the practicability of the device.

[0011] In one embodiment, two sets of guide grooves are provided on the top surface of the mounting block, and guide shafts are provided in the two sets of guide grooves. Two sets of guide blocks are provided at the bottom end of the limit block.

The second spring is sleeved on the two sets of guide shafts, and the two ends of the second spring respectively abut against the ends of the guide grooves away from the pressing column and the guide blocks. The stability of the limit block when sliding can be improved by the cooperation of the guide grooves, the guide shafts and the guide blocks, and the second spring is sleeved on the guide shafts, and the guide shafts can guide the expansion and contraction of the second spring, thereby improving the service life of the second spring. At the same time, two sets of second springs are provided relatively to improve the balance of the thrust applied to the limit block.

[0012] In one embodiment, the top of the limit block near the end of the pressing column is provided with a wedge-shaped surface, the lower end of the wedge-shaped surface faces the pressing column, and the bottom end of the block can contact the wedge-shaped surface.

At this time, the block continues to move downward and the limit block can move away from the pressing column under the guidance of the wedge-shaped surface. At this time, the second spring is compressed and contracted. When the block moves downward to contact the stop block and is misaligned with the limit block, the reaction force of the second spring causes the limit block to move in the opposite direction. The limit block moves in the opposite direction so that the block can be stuck between the stop block and the limit block, thereby facilitating automatic fixing of the block and conveniently fixing the block.

By adjusting the third driving component to drive the middle part of the multiple groups of spring sheets to bulge out the bottom end of the compression plate, at this time, the multiple groups of spring sheets can squeeze the silicone pad to make the silicone pad bulge downward, thereby facilitating the device to compress and stop bleeding on the recessed part. At the same time, the two ends of the spring sheet gradually move toward the middle part so that the two ends of the spring sheet cancel the resistance to the silicone pad, thereby reducing the pressure on the skin around the puncture point of the recessed part. By adjusting the third driving component to drive the middle part of the multiple groups of spring sheets to be recessed toward the top surface of the giving way cavity, at this time, the multiple groups of spring sheets can drive the silicone pad to be recessed toward the top surface of the giving way cavity, thereby facilitating the compression plate hemostasis on the protruding part.

[0038] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0039] See also Figures 1 to 5 In one embodiment, a compression hemostasis device for arterial intervention surgery includes a substrate 10 and a compression mechanism. Velcro 101 is connected to both ends of the substrate 10. A mounting seat 102 is provided at the top of the substrate 10. A through hole 103 is opened at the top of the mounting seat 102 and vertically penetrates the mounting seat 102 and the substrate 10. The compression mechanism includes a pressing column 20 and a positioning mechanism 30.

[0040] Among them, the pressing column 20 passes through the through hole 103, and a compression plate 201 is arranged at the bottom end, a silicone pad 202 is arranged at the bottom end of the compression plate 201, and a first spring 203 is sleeved on the pressing column 20, and the two ends of the first spring 203 respectively press against the top of the mounting seat 102 and the top of the pressing column 20.

[0041] The positioning mechanism 30 includes a mounting block 301, a limiting block 303, a second spring 305, a clamping block 304, a first driving assembly and a second driving assembly; the mounting block 301 can be slidably arranged in the mounting seat 102 in the vertical direction, and a stop block 302 is arranged at one end of the mounting seat 102 close to the pressing column 20, and the limiting block 303 can be slidably arranged at the top of the mounting block 301 horizontally, and the second spring 305 connects the limiting block 303 and the mounting block 301, and is used to apply pressure to the limiting block 303 toward the pressing column 20 thrust, the card block 304 can be slidably arranged in the mounting seat 102 in the vertical direction and is connected to the pressing column 20, the card block 304 can slide and be clamped between the limit block 303 and the stop block 302, the first driving component is arranged on the mounting seat 102 and is connected to the mounting block 301, and is used to drive the mounting block 301 to slide, the second driving component is arranged on the mounting block 301 and is connected to the limit block 303, and is used to drive the limit block 303 to slide, so as to cancel the limit on the card block 304.

[0042] Specifically, two groups of guide grooves 3011 are relatively opened on the top surface of the mounting block 301, and guide shafts 3012 are arranged in the two groups of guide grooves 3011. Two groups of guide blocks 3033 are relatively arranged at the bottom end of the limit block 303. The two groups of guide blocks 3033 can be slidably arranged in the two groups of guide grooves 3011 along the horizontal direction, and are sleeved on the two groups of guide shafts 3012. The two groups of guide shafts 3012 are sleeved with second springs 305, and the two ends of the second spring 305 respectively press against the end of the guide groove 3011 away from the pressing column 20 and the guide block 3033. The cooperation of the guide groove 3011, the guide shaft 3012 and the guide block 3033 can improve the stability of the limit block 303 when sliding, and the second spring 305 is sleeved on the guide shaft 3012, and the guide shaft 3012 can guide the expansion and contraction of the second spring 305, thereby improving the service life of the second spring 305. At the same time, two groups of the second spring 305 are relatively arranged, which can improve the balance of the thrust applied to the limit block 303. The limit block 303 is provided with a wedge-shaped surface at the top end near the end of the pressing column 20, and the lower end of the wedge-shaped surface faces the pressing column 20, and the bottom end of the clamping block 304 can contact the wedge-shaped surface.

[0043] In the above embodiment, according to the magnitude of the pressure applied to the puncture point, the base plate 10 is fixed to the patient by the Velcro 101, and then the first driving component is pre-adjusted to drive the mounting block 301 to slide, and the sliding of the mounting block 301 drives the stop block 302 and the limit block 303 to slide, so that the stop block 302 and the limit block 303 slide to the specified position. It can be understood that the closer the position of the stop block 302 and the limit block 303 is to the puncture point, the longer the distance the block 304 moves downward, and the greater the pressure applied to the puncture point. Conversely, the farther the position of the stop block 302 and the limit block 303 is from the puncture point, the shorter the distance the block 304 moves downward, and the smaller the pressure applied to the puncture point. After the arterial sheath is removed, pressure is immediately applied to the top of the pressing column 20 to move the pressing column 20 downward. The downward movement of the pressing column 20 drives the compression plate 201, the silicone pad 202 and the block 304 to move downward, and causes the first spring 203 to be compressed and contracted. When the block 304 moves downward and contacts the wedge-shaped surface, the block 304 continues to move downward, and under the guidance of the wedge-shaped surface, the limit block 303 can be moved away from the pressing column 20, and the second spring 305 can be compressed and contracted. When the block 304 moves downward and contacts the stop block 302 and is misaligned with the limit block 303, the block 304 stops moving downward, and the reaction force of the second spring 305 causes the limit block 303 to move in the opposite direction. At this time, the bottom surface of the limit block 303 is against the top surface of the block 304, so that the block 304 is stuck between the limit block 303 and the stop block 302, thereby automatically fixing the pressing column 20. At this time, the compression plate 201 and the silicone pad 202 move downward to apply a preset pressure to the puncture point. The speed of applying pressure to the puncture point is increased by directly driving the compression plate 201 to move, and the size of the pressure applied to the puncture point can be controlled by pre-adjusting the positions of the limit block 303 and the stop block 302, thereby improving the practicality of the device.

[0044] Specifically in the above embodiment, the compression plate 201 and the silicone pad 202 are both transparent, which facilitates observation of the puncture point while compressing the puncture point.

[0045] See also Figures 2 to 5 In one embodiment, the first driving component includes a first screw rod 306; a mounting cavity 1031 is opened around the through hole 103, and the mounting block 301 and the clamping block 304 can be slidably arranged in the mounting cavity 1031 along the vertical direction. The first screw rod 306 is arranged in the vertical direction and can be rotatably arranged in the mounting cavity 1031. The first screw rod 306 is threadedly connected to the mounting block 301.

[0046] In the above embodiment, by rotating the first screw 306, the first screw 306 rotates and cooperates with the thread of the mounting block 301 to drive the mounting block 301 to move downward, and by rotating the first screw 306 in the opposite direction, the first screw 306 rotates in the opposite direction and cooperates with the thread of the mounting block 301 to drive the mounting block 301 to move upward, and by stopping the rotation of the first screw 306, the first screw 306 and the thread of the mounting block 301 can be engaged to fix the mounting block 301, so that the driving and fixing of the mounting block 301 is convenient.

[0047] See also Figures 2 to 5 In one embodiment, the second driving assembly includes a rotating rod 307 and a lever 308; the rotating rod 307 is arranged in a vertical direction and is rotatably arranged in the installation cavity 1031. A through slot 3031 is vertically opened at the top of the limit block 303. The rotating rod 307 passes through the through slot 3031 and the installation block 301 and is away from the pressing column 20. One end of the lever 308 can be slidably arranged on the rotating rod 307 in a vertical direction, and a lever shaft 3081 is arranged at the other end. A lever groove 3032 is opened on the side wall of the through slot 3031 away from the pressing column 20, and the lever shaft 3081 can be slidably arranged in the lever groove 3032 in a horizontal direction.

[0048] Specifically, a positioning groove 3071 is opened on the circumference of the rotating rod 307, a connecting sleeve 3082 is provided at one end of the lever 308, a positioning block 3083 is provided on the inner wall of the connecting sleeve 3082, the connecting sleeve 3082 is sleeved on the rotating rod 307, and the positioning block 3083 is slidably set in the positioning groove 3071 along its axial direction.

[0049] In the above embodiment, the lever 308 can be driven to rotate by rotating the rotating rod 307. The lever 308 rotates to make the lever shaft 3081 slide in the lever groove 3032 in the horizontal direction. At this time, the lever 308 can squeeze the side wall of the through groove 3031 to move the limit block 303 away from the pressing column 20. At this time, the second spring 305 is compressed and contracted, and the limit block 303 moves away from the pressing column 20 to cancel the limit on the top of the block 304. At this time, the reaction force of the first spring 203 can make the pressing column 20 move upward and reset. The upward movement of the pressing column 20 can drive the block 304 and The compression plate 201 moves upward, thereby facilitating the rapid cancellation of the pressure applied to the puncture point. When the pressing column 20 moves upward and resets, the force applied to the rotating rod 307 is canceled. At this time, the reaction force of the second spring 305 causes the limit block 303 to move in the opposite direction and reset. The limit block 303 moves in the opposite direction through the shifting groove 3032 and the shifting shaft 3081, so that the shifting rod 308 can drive the rotating rod 307 to rotate in the opposite direction and reset, thereby facilitating the application of pressure to the pressing column 20 again so that the blocking block 304 is clamped between the limit block 303 and the stop block 302, which is convenient for the reuse of the device.

[0051] In the above embodiment, by providing a cover plate 40 to cover the opening of the storage groove 1021, the first screw 306 and the rotating rod 307 can be prevented from being exposed to the outside, thereby preventing accidental touching of the first screw 306 and the rotating rod 307, and improving the stability of the device applying pressure to the puncture point. The cover plate 40 is magnetically connected to the mounting base 102, and it is convenient to open and close the cover plate 40.

The bottom ends of the multiple groups of spring sheets 501 are flush with the pressure plate 201, and the middle parts are connected to the silicone pad 202. Multiple groups of limiting grooves 2012 are provided at both ends of the top surface of the clearance cavity 2011 corresponding to the multiple groups of spring sheets 501. Connecting shafts 5011 are provided at both ends of the multiple groups of spring sheets 501. The connecting shafts 5011 at both ends can be slidably arranged in the limiting grooves 2012 at both ends along the length direction of the pressure plate 201. The third driving component is arranged in the pressing column 20 and is connected to the middle parts of the multiple groups of spring sheets 501, and is used to drive the middle parts of the multiple groups of spring sheets 501 to protrude from the bottom end of the pressure plate 201 or to be recessed toward the top surface of the clearance cavity 2011.

[0053] Specifically, the third driving assembly includes a second screw rod 503 and a connecting column 502; a mounting hole 204 is opened in the pressing column 20, and the connecting column 502 can be slidably set on the bottom surface of the mounting hole 204 in the vertical direction, and extend into the make way cavity 2011, and is provided with a connecting plate 5021, which is connected to the middle part of the multiple groups of spring leaves 501. The second screw rod 503 is set in the vertical direction and is rotatably set in the mounting hole 204. The second screw rod 503 is threadedly connected to the connecting column 502.

[0054] In the above embodiment, by rotating the second screw 503, the second screw 503 rotates and cooperates with the thread of the connecting column 502 to drive the connecting column 502 to move downward. The connecting column 502 moves downward and can squeeze the middle of the multiple groups of spring leaves 501 through the connecting plate 5021 to move the protruding bottom of the compression plate 201 downward. At this time, the multiple groups of spring leaves 501 can squeeze the silicone pad 202 to make the silicone pad 202 bulge downward, thereby facilitating the device to compress and stop bleeding at the recessed part. At the same time, the two ends of the spring leaf 501 gradually move toward the middle so that the two ends of the spring leaf 501 cancel the resistance to the silicone pad 202, thereby reducing the pressure on the skin around the puncture point of the recessed part. By rotating the second screw 503 in the opposite direction, the second screw 503 rotates in the opposite direction to cooperate with the thread of the connecting column 502 to drive the connecting column 502 to move upward. The connecting column 502 moves upward and can pass through the connecting plate The connecting plate 5021 drives the middle part of the multiple groups of spring leaves 501 to be concave toward the top surface of the giving way cavity 2011. At this time, the multiple groups of spring leaves 501 can drive the silicone pad 202 to be concave toward the top surface of the giving way cavity 2011, so as to facilitate the pressing plate to stop bleeding on the protruding part. At the same time, the two ends of the spring leaf 501 gradually move toward the middle so that the two ends of the spring leaf 501 cancel the resistance to the silicone pad 202, thereby reducing the pressure on the skin around the puncture point of the protruding part, facilitating the compression and hemostasis of the concave and convex parts, and reducing the pressure on the skin around the puncture points of the concave and convex parts, thereby improving the practicality of the device and the comfort of use. The second screw rod 503 can be stopped to fix the connecting column 502, so as to facilitate the fixing of the protrusion or depression degree of the multiple groups of spring leaves 501, and facilitate the adjustment of the protrusion or depression degree of the multiple groups of spring leaves 501 according to actual conditions.

[0055] See also Figure 2 , Figure 3 , Fig. 9 , Fig.10 In one embodiment, the pressing mechanism further includes a locking assembly 60; a connecting ring 3041 is provided on the block 304, and a ring groove 205 is provided on the circumference of the pressing column 20. The connecting ring 3041 can be rotatably sleeved in the ring groove 205 coaxially with the pressing column 20. The locking assembly 60 is provided on the mounting seat 102 and connected to the pressing column 20 for locking the rotation of the pressing column 20.

[0056] Specifically, the locking assembly 60 includes a locking block 601, a pull rod 602 and a third spring 603; a mounting groove 1032 is provided around the through hole 103, the locking block 601 can be horizontally slidably set in the mounting groove 1032, and a plurality of groups of locking grooves 206 are evenly provided around the pressing column 20, one end of the locking block 601 can be inserted into the locking groove 206 and can slide in a vertical direction, and a pull rod 602 is provided at the other end of the locking block 601, one end of the pull rod 602 extends to the outside of the mounting seat 102, and a holding block 604 is provided, and the third spring 603 is sleeved on the pull rod 602, and the two ends respectively resist the locking block 601 and the end wall of the mounting groove 1032.

[0057] When the pressing plate 201 and the silicone pad 202 are rotated and adjusted to a suitable position, the pulling force applied to the holding block 604 is cancelled, and the reaction force of the third spring 603 can cause the locking block 601 to move in the opposite direction, so that the locking block 601 is inserted into the corresponding locking groove 206, and the pressing plate 201 and the silicone pad 202 are locked at this time, thereby preventing the pressing plate 201 from rotating. The pressing plate 201 and the silicone pad 202 are convenient to rotate and lock, and the horizontal position of the pressing plate 201 and the silicone pad 202 can be adjusted according to needs, thereby improving the practicality of the device.

[0058] The specific implementation of the above-mentioned compression hemostasis device for arterial intervention surgery is as follows:

[0059] According to the amount of pressure applied to the puncture point, the base plate 10 is fixed to the patient by the Velcro 101, and then the first screw 306 is rotated in advance. The first screw 306 rotates and cooperates with the thread of the mounting block 301 to drive the mounting block 301 to move downward. The downward movement of the mounting block 301 drives the stop block 302 and the limit block 303 to move downward. When the stop block 302 and the limit block 303 move downward to the specified position, the first screw 306 is stopped from rotating to fix the mounting block 301, thereby fixing the stop block 302 and the limit block 303.

[0060] After the arterial sheath is removed, pressure is immediately applied to the top of the pressing column 20 to move the pressing column 20 downward. The downward movement of the pressing column 20 drives the compression plate 201, the silicone pad 202 and the clamping block 304 to move downward, and compresses and contracts the first spring 203. When the clamping block 304 moves downward and contacts the wedge-shaped surface, the clamping block 304 continues to move downward. Under the guidance of the wedge-shaped surface, the limit block 303 can be moved away from the pressing column 20, and the second spring 305 can be compressed and contracted. When the clamping block 304 moves downward and contacts the stop block 302 and is misaligned with the limit block 303, the clamping block 304 stops moving downward. The pressing column 20 is automatically fixed by the downward movement of the compression plate 201 and the silicone pad 202. The speed of applying pressure to the puncture point is increased by directly driving the compression plate 201 to move, and the size of the pressure applied to the puncture point can be controlled by pre-adjusting the positions of the limiting block 303 and the stop block 302, thereby improving the practicability of the device.

[0061] After applying pressure to the puncture point for a period of time, by rotating the first screw rod 306 in the opposite direction, the first screw rod 306 rotates in the opposite direction to cooperate with the thread of the mounting block 301 to drive the mounting block 301 to move upward, and the mounting block 301 moves upward to drive the stop block 302 and the limit block 303 to move upward, at this time, the block 304 and the pressing column 20 move upward, and the pressing column 20 moves upward to drive the compression plate 201 and the silicone pad 202 to move upward, thereby performing a decompression operation on the puncture point. When it is necessary to cancel the pressure applied to the puncture point, the lever 308 can be driven to rotate by rotating the rotating rod 307, and the lever 308 rotates to make the lever shaft 3081 slide in the lever groove 3032 in the horizontal direction. At this time, the lever 308 can squeeze the side wall of the through groove 3031 to move the limit block 303 away from the pressing column 20. At this time, the second spring 305 The first spring 203 then pushes the locking cam 304 away from the locking cam 306, and the locking cam 304 is released to the locking cam 306, thereby releasing the locking cam 306.
