Description

Technical Field

[0001] This utility model belongs to the field of compression device technology, and specifically relates to a puncture point compression device for puncture surgery with adjustable tightness. Background Technology

[0002] A puncture site compressor is a medical device primarily used to apply physical pressure to the puncture site after vascular or tissue puncture. The puncture site compressor mainly consists of a compression head, a fixing device, and an adjusting component. By rotating the adjusting component, the pressure applied by the compression head to the patient's puncture site can be adjusted according to the actual situation.

[0003] The pressure applied by the compression head to the puncture site is adjusted based on the dynamic changes in bleeding. This process mainly includes three stages: initial hemostasis, stable hemostasis, and late-stage healing. During these three stages, medical staff need to adjust the pressure of the compression head using the adjustment mechanism. Since the three adjustment stages are spaced far apart, patients are prone to accidentally touching the adjustment mechanism during this period. This can cause the pressure applied by the compression head to the puncture site to change before the next stage is initiated, thus affecting the hemostasis and healing effect of the puncture compression device.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In response to the problems in related technologies, this utility model proposes a puncture point compressor for puncture surgery with adjustable tightness, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a puncture point compressor for puncture surgery with adjustable tension, comprising a support plate, fixing components on both sides of the support plate, a compression component at the bottom of the support plate, and a driving component at the top of the support plate. The driving component is poweredly connected to the compression component, and an elastic locking component is provided at the driving end of the driving component. A pressing component is provided on one side of the elastic locking component, and the pressing component is poweredly connected to the elastic locking component.

[0008] The fixing component is used to fix the support plate to the puncture point, the driving component is used to drive the compression component so that the compression component compresses the puncture point, the elastic locking component is used to lock the driving end of the driving component, and the pressing component is used to squeeze the elastic locking component so that the elastic locking component no longer locks the driving end of the driving component.

[0009] Furthermore, the fixing component includes a connecting frame, which is provided on both sides of the support plate. An opening slot is provided on one side of the connecting frame, and a fixing strap is sleeved inside the connecting frame. The surface of the fixing strap is provided with Velcro.

[0010] Furthermore, the compression assembly includes a fixed frame, an installation frame is movably connected inside the fixed frame, a silicone extrusion block is disposed inside the installation frame, a movable tube is disposed on the top of the support plate, and the bottom end of the movable tube penetrates the support plate and is fixedly connected to the installation frame.

[0011] Furthermore, a storage groove is provided on one side of the mounting frame, and a fixing hole is provided on the inner wall of the storage groove. The fixing hole passes through the mounting frame and the silicone extrusion block, and a fixing nail is inserted into the fixing hole. A connecting block is movably connected inside the storage groove. The connecting block is fixedly connected to the fixing nail, and a pull groove is provided between the connecting block and the top of the mounting frame.

[0012] Furthermore, the driving assembly includes a fixed cylinder, which is fixedly connected to the top of the support plate. A driving screw is rotatably connected inside the fixed cylinder and threadedly connected to a movable pipe. A guide groove is formed on the inner wall of the fixed cylinder, and a guide block is movably connected inside the guide groove. The guide block is fixedly connected to the movable pipe. A knob is provided on the top of the fixed cylinder, and the top end of the driving screw is fixedly connected to the knob. A scale groove is formed on the outer surface of the fixed cylinder.

[0013] Furthermore, the elastic locking assembly includes a locking gear, which is fixedly connected to the outer surface of the drive screw. A locking gear cylinder meshes with the outer surface of the locking gear, and a connecting rod is fixedly connected to the outer surface of the locking gear cylinder. A T-shaped limiting rod is fixedly connected to the top of the inner wall of the fixed cylinder, and the T-shaped limiting rod is movably connected to the connecting rod. A locking spring is fixedly connected between the top of the locking gear and the top of the inner wall of the fixed cylinder.

[0014] Furthermore, the pressing assembly includes a pushing groove, which is formed on the fixed cylinder. An arc-shaped pushing plate is movably connected inside the pushing groove. A pushing rod is fixedly connected to the inner wall of the arc-shaped pushing plate. An inclined pushing block is fixedly connected to one end of the pushing rod. A T-shaped support rod is fixedly connected to the inner wall of the fixed cylinder. The inclined pushing block is movably connected to the T-shaped support rod. A connecting plate is fixedly connected to the outer surface of the T-shaped support rod. A pushing spring is fixedly connected between the connecting plate and the inclined pushing block.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model allows the locking end of the elastic locking component to move upward and release the locking of the driving component by pressing the pressing component. At this time, the driving component can rotate and adjust the height of the compression component, thereby adjusting the pressure of the compression component on the puncture point. The entire adjustment process requires pressing the pressing component and rotating the driving component at the same time. Both operations are indispensable. This setting can effectively prevent the phenomenon of the compression force of the compression component changing due to the patient accidentally touching the driving component, thereby ensuring the hemostasis and healing effect of the puncture compression device.

[0017] 2. This utility model releases the arc-shaped push plate, allowing it to reset under the support of the T-shaped support rod and the push of the push spring. The locking toothed cylinder moves downward under the push of the locking spring. When the locking toothed cylinder cannot engage with the locking gear, the locking gear can be slightly rotated by the knob and drive screw. When the locking gear and the locking toothed cylinder are aligned vertically, the locking toothed cylinder can automatically engage with the locking gear under the push of the locking spring. Since the drive screw does not need to rotate too much, the force of the silicone extrusion block on the puncture point will not change much. The above setting makes it convenient to lock the drive screw.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is a puncture point compressor for puncture surgery with adjustable tension, including a support plate 1, fixing components 2 on both sides of the support plate 1, a compression component 3 at the bottom of the support plate 1, a driving component 4 at the top of the support plate 1, the driving component 4 being poweredly connected to the compression component 3, an elastic locking component 5 at the driving end of the driving component 4, and a pressing component 6 on one side of the elastic locking component 5, the pressing component 6 being poweredly connected to the elastic locking component 5.

[0032] The fixing component 2 is used to fix the support plate 1 at the puncture point, the driving component 4 is used to drive the compression component 3 so that the compression component 3 compresses the puncture point, the elastic locking component 5 is used to lock the driving end of the driving component 4, and the pressing component 6 is used to squeeze the elastic locking component 5 so that the elastic locking component 5 no longer locks the driving end of the driving component 4.

[0033] The support plate 1 is fixed to the patient's wrist by the fixing component 2, and the support plate 1 is positioned above the puncture point. Then, the pressing component 6 is pressed, which causes the locking end of the elastic locking component 5 to move upward under the pressure of the pressing component 6 and directly release the lock on the driving end of the driving component 4. Then, the driving component 4 is rotated, which causes the compression component 3 to move downward under the drive of the driving component 4, and the compression end of the compression component 3 can squeeze the patient's puncture point. Finally, the pressing component 6 is released, so that the elastic locking component 5 can lock the driving component 4 again.

[0034] By pressing the pressing component 6, the locking end of the elastic locking component 5 can move upward and release the locking of the driving component 4. At this time, the driving component 4 can rotate and adjust the height of the compression component 3, thereby adjusting the pressure of the compression component 3 on the puncture point. The entire adjustment process requires pressing the pressing component 6 while rotating the driving component 4. Both operations are indispensable. This setting can effectively prevent the phenomenon that the pressure of the compression component 3 changes due to the patient accidentally touching the driving component 4, thereby ensuring the hemostasis and healing effect of the puncture compressor.

[0035] In one embodiment, the fixing component 2 includes a connecting frame 201, which is provided on both sides of the support plate 1. An opening slot 202 is provided on one side of the connecting frame 201. A fixing strap 203 is sleeved inside the connecting frame 201, and the surface of the fixing strap 203 is provided with Velcro 204.

[0036] The opening slot 202 allows one end of the fixation strap 203 to be moved inside the connecting frame 201, making it convenient to replace the fixation strap 203. When applying pressure to the puncture point, the support plate 1 is placed at the position requiring pressure, and then the two fixation straps 203 are connected together using Velcro 204s provided on their inner and outer sides, thus securing the support plate 1 to the patient's wrist. Due to the tensile force between the two connected fixation straps 203, the fixation straps 203 will not detach from the inside of the connecting frame 201 when the two fixation straps 203 are secured to the support plate 1 through the connecting frame 201.

[0037] In one embodiment, the compression component 3 includes a fixed frame 301, an installation frame 302 is movably connected inside the fixed frame 301, a silicone extrusion block 303 is disposed inside the installation frame 302, a movable tube 304 is disposed on the top of the support plate 1, and the bottom end of the movable tube 304 passes through the support plate 1 and is fixedly connected to the installation frame 302.

[0038] By moving the movable tube 304, the mounting frame 302 can be moved downwards, causing the silicone compression block 303 to come into contact with and compress the puncture point under the action of the mounting frame 302. The silicone compression block 303 is designed to ensure patient comfort when compressing the puncture point.

[0039] In one embodiment, for the mounting frame 302, a storage groove 305 is provided on one side of the mounting frame 302, and a fixing hole 306 is provided on the inner wall of the storage groove 305. The fixing hole 306 passes through the mounting frame 302 and the silicone extrusion block 303. A fixing nail 307 is inserted into the fixing hole 306. A connecting block 308 is movably connected to the inside of the storage groove 305. The connecting block 308 is fixedly connected to the fixing nail 307. A pull groove 309 is provided between the connecting block 308 and the top of the mounting frame 301.

[0040] The mounting frame 302 can be completely moved out of the fixed frame 301 by moving the tube 304. At this time, the connecting block 308 is moved out of the storage groove 305 by pulling the groove 309. Simultaneously, the fixing pin 307 moves out of the fixing hole 306 under the action of the connecting block 308, allowing the silicone extrusion block 303 to be moved out of the mounting frame 302. This design makes it convenient to replace the silicone extrusion block 303. Combined with the easily replaceable fixing strap 203, the compressor can be reused; only the silicone extrusion block 303 and the fixing strap 203 need to be replaced. Because the mounting frame 302 is always inside the fixed frame 301 when the silicone extrusion block 303 is pressing the puncture point, the connecting block 308 will not move out of the storage groove 305 due to the constraint of the fixed frame 301. Therefore, the silicone extrusion block 303 will not detach from the mounting frame 302 during use, thanks to the fixing pin 307.

[0041] In one embodiment, the drive assembly 4 includes a fixed cylinder 401, which is fixedly connected to the top of the support plate 1. A drive screw 402 is rotatably connected inside the fixed cylinder 401 and threadedly connected to the moving tube 304. A guide groove 403 is provided on the inner wall of the fixed cylinder 401, and a guide block 404 is movably connected inside the guide groove 403. The guide block 404 is fixedly connected to the moving tube 304. A knob 405 is provided on the top of the fixed cylinder 401, and the top end of the drive screw 402 is fixedly connected to the knob 405. A scale groove 406 is provided on the outer surface of the fixed cylinder 401.

[0042] Rotating the drive screw 402 via the knob 405 drives the moving tube 304 downwards. This downward movement causes the guide block 404 to slide within the guide groove 403. The guide block 404 and guide groove 403 ensure high stability during the vertical movement of the moving tube 304. Medical personnel can monitor the height of the moving tube 304 using the scale groove 406. The scale groove 406 allows for precise adjustment of the pressure applied by the silicone extrusion block 303 by adjusting the height of the moving tube 304.

[0043] In one embodiment, the elastic locking assembly 5 includes a locking gear 501, which is fixedly connected to the outer surface of the drive screw 402. The outer surface of the locking gear 501 meshes with a locking gear cylinder 502. A connecting rod 503 is fixedly connected to the outer surface of the locking gear cylinder 502. A T-shaped limiting rod 504 is fixedly connected to the top of the inner wall of the fixed cylinder 401. The T-shaped limiting rod 504 is movably connected to the connecting rod 503. A locking spring 505 is fixedly connected between the top of the locking gear 501 and the top of the inner wall of the fixed cylinder 401.

[0044] The locking spring 505 can push the locking gear cylinder 502 downwards, causing the locking gear cylinder 502 to move downwards under the action of the T-shaped limit rod 504 and directly mesh with the locking gear 501. At this time, the locking gear cylinder 502 will not rotate under the restriction of the two T-shaped limit rods 504. Thus, the locking gear cylinder 502 can lock the drive screw 402 through the locking gear 501, so that the drive screw 402 will not rotate arbitrarily. At the same time, the locking gear cylinder 502 will not separate from the locking gear 501 arbitrarily under the push of the locking spring 505, thus ensuring the overall locking effect of the locking gear cylinder 502.

[0045] In one embodiment, the pressing assembly 6 includes a pushing groove 601, which is formed on a fixed cylinder 401. An arc-shaped pushing plate 602 is movably connected inside the pushing groove 601. A pushing rod 603 is fixedly connected to the inner wall of the arc-shaped pushing plate 602. An inclined pushing block 604 is fixedly connected to one end of the pushing rod 603. A T-shaped support rod 605 is fixedly connected to the inner wall of the fixed cylinder 401. The inclined pushing block 604 is movably connected to the T-shaped support rod 605. A connecting plate 606 is fixedly connected to the outer surface of the T-shaped support rod 605. A pushing spring 607 is fixedly connected between the connecting plate 606 and the inclined pushing block 604.

[0046] When the drive screw 402 is rotated by the knob 405, the arc-shaped push plate 602 is pressed, which causes the arc-shaped push plate 602 to push the inclined push block 604 through the push rod 603. The inclined push block 604 then presses the connecting rod 503 upward through its inclined surface, which causes the connecting rod 503 to drive the locking gear cylinder 502 to move upward continuously and directly separate from the locking gear 501, so that the drive screw 402 can rotate normally. When locking the drive screw 402 is required, simply release the arc-shaped push plate 602. At this time, the push spring 607 pushes the tilting push block 604, causing it to reset under the support and guidance of the T-shaped support rod 605. The locking gear cylinder 502 then moves downwards under the push of the locking spring 505 and engages with the locking gear 501. If the locking gear cylinder 502 cannot engage with the locking gear 501, simply rotate the locking gear 501 slightly using the knob 405 and drive screw 402. When the locking gear 501 and locking gear cylinder 502 are aligned vertically, the locking gear cylinder 502 automatically engages with the locking gear 501 under the push of the locking spring 505. During this process, the T-shaped support rod 605 ensures the stability of the tilting push block 604 during movement, while the push spring 607 prevents the arc-shaped push plate 602 from moving arbitrarily without significant external force.

[0047] Through the above technical solution, 1. By pressing the pressing component 6, the locking end of the elastic locking component 5 can move upward and release the locking of the driving component 4. At this time, the driving component 4 can rotate and adjust the height of the compression component 3, thereby adjusting the pressure of the compression component 3 on the puncture point. The entire adjustment process requires pressing the pressing component 6 while rotating the driving component 4. Both operations are indispensable. This setting can effectively prevent the phenomenon of the compression force of the compression component 3 changing due to the patient accidentally touching the driving component 4, thereby ensuring the hemostasis and healing effect of the puncture compressor; 2. By releasing the arc-shaped push plate 602, the tilting push block 604 T-shaped support rod The locking cylinder 502 is reset under the support of the locking spring 605 and the push of the pushing spring 607. The locking cylinder 502 moves downward under the push of the locking spring 505. When the locking cylinder 502 cannot engage with the locking gear 501, the locking gear 501 can be slightly rotated by the knob 405 and the drive screw 402. When the locking gear 501 and the locking cylinder 502 are aligned vertically, the locking cylinder 502 can automatically engage with the locking gear 501 under the push of the locking spring 505. Since the drive screw 402 does not need to rotate too much, the force of the silicone extrusion block 303 on the puncture point will not change much. The above settings make it convenient to lock the drive screw 402.
