Description

Technical Field

[0001] This invention belongs to the field of surgical instruments for cardiac medicine, and specifically relates to a dynamic pressure hemostasis device for postoperative cardiac pacemaker implantation. Background Technology

[0002] The dynamic pressure hemostasis device after pacemaker implantation is a medical device used to help stop bleeding in the wound after pacemaker implantation. It applies adjustable pressure to the wound to achieve hemostasis while improving patient comfort and convenience.

[0003] Traditional dynamic pressure hemostasis devices have significant design limitations. They can only adjust the overall size according to the patient's chest circumference, while the position of the air bladder remains fixed and cannot be fine-tuned according to the specific location of the surgical wound. This defect can cause multiple clinical problems and ultimately lead to low versatility of the device.

[0004] When the balloon is misaligned with the wound, two core problems arise. First, if the misalignment is severe, the wound will be completely unpressured, failing to provide effective compression and directly causing hemostasis failure. This can lead to serious safety risks such as postoperative massive bleeding. Second, even if the edge of the balloon barely covers the wound, the pressure will be concentrated in the non-wound area, resulting in insufficient pressure at the wound site. This not only significantly reduces hemostasis efficiency and prolongs hemostasis time but also increases the probability of wound infection.

[0005] These hemostasis problems caused by the inability to fine-tune the device's position make it difficult to adapt to the wound needs of different patients and different surgeries, ultimately resulting in low clinical versatility and an inability to widely meet diverse hemostasis scenarios. Summary of the Invention

[0006] Based on the technical problems existing in the prior art, the present invention provides a dynamic pressure hemostasis device for postoperative cardiac pacemaker surgery.

[0007] According to the technical solution of the present invention, the present invention provides a dynamic pressure hemostasis device for postoperative cardiac pacemaker implantation, comprising: The frame and the first slide groove are provided. The first slide groove is opened inside the frame and connected to the outside. A slide plate is slidably connected inside the first slide groove. Several airbags are fixedly connected to one side of the slide plate. A connecting pipe is fixedly connected between the several airbags, and the inner cavity of the connecting pipe is connected to the inner cavity of the several airbags. A second small solenoid valve is fixedly connected to the connection point between the connecting pipe and the several airbags. A small air pump is fixedly connected to the other side of the slide plate, and the output shaft of the small air pump is fixedly connected to the connecting pipe. A plurality of exhaust pipes are fixedly connected to a plurality of airbags, and one end of each exhaust pipe passes through one side of the slide plate and extends to the other side of the slide plate. One end of each exhaust pipe is fixedly connected to a first small solenoid valve, and a small pressure detector is provided on each of the first small solenoid valves. The control panel is fixedly connected to the other side of the slide plate and is electrically connected to a small air pump, a first small solenoid valve and a small pressure detector.

[0008] In this technical solution, the user can adjust the position of several airbags according to the location of the patient's wound.

[0009] The above technical solution further includes: Two limiting grooves are formed in the slide plate and connected to the first slide groove. Each of the two limiting grooves is slidably connected to an extrusion block, and each of the two extrusion blocks is threadedly connected to a bolt. A drive assembly, located inside the slide plate, is used to rotate two bolts.

[0010] In this technical solution, several airbags are ensured to be stably confined at the patient's wound location.

[0011] In the above technical solution, the driving component further includes: Two through slots are formed inside the slide plate and are respectively connected to two limiting slots. A connecting rod is rotatably connected to each of the two through slots, and one end of each connecting rod extends into the two limiting slots and is fixedly connected to two bolts respectively. A gear groove is formed inside the slide plate and communicates with two through slots. Two first bevel gears are rotatably connected inside the gear groove, and one end of each of the two first bevel gears extends into the two through slots and is fixedly connected to the other end of each of the two connecting rods. A second bevel gear meshes between the two first bevel gears. A rotating rod is fixedly connected to the second bevel gear, and one end of the rotating rod passes through the inner wall of the gear groove and extends to the outside. A fixing component is located on the rotating rod and is used to fix the rotating rod in place.

[0012] In this technical solution, it is ensured that the user can control the two bolts to rotate in opposite directions.

[0013] In the above technical solution, the fixing component further includes: The threaded groove is formed on the circumference of the rotating rod, and a threaded sleeve is threadedly connected to the threaded groove, and the circumference of the threaded sleeve is provided with anti-slip texture.

[0014] In this technical solution, it is ensured that the rotating rod will not be affected by external factors and will not rotate.

[0015] Furthermore, the above technical solution also includes: Two elastic bands are provided on both sides of the frame. One end of one elastic band is fixedly connected to a hook and loop fastener, and one end of the other elastic band is fixedly connected to a barbed hook and loop fastener, with the barbed hook and loop fastener and the hook and loop fastener fitting together. Several slots are respectively opened on both sides of the frame, and each of the slots has a plug inserted into it, and the plugs are respectively fixedly connected to the other end of two elastic bands.

[0016] In this technical solution, it is ensured that the user can fix the frame at any height above the user's chest.

[0017] In the above technical solution, one end of the connecting rod is rotatably connected to the limiting groove, one end of the first bevel gear is rotatably connected to the through groove, and the second bevel gear is located in the gear groove and rotatably connected to the gear groove.

[0018] In this technical solution, it is ensured that when the connecting rod rotates, one end of the connecting rod can rotate normally in the limiting groove, and that when the first bevel gear rotates, one end of the first bevel gear can rotate normally in the through groove. At the same time, it is ensured that when the second bevel gear rotates, the second bevel gear can rotate normally in the gear groove.

[0019] In the above technical solution, the rotating rod is located in the gear groove and rotatably connected to the gear groove, and the circumference of the rotating rod is provided with anti-slip texture.

[0020] In this technical solution, it is ensured that the rotating rod can rotate normally within the gear groove when it rotates. Furthermore, because the rotating rod has anti-slip texture on its periphery, when the user rotates the rotating rod by hand, the anti-slip texture on the periphery of the rotating rod increases the friction of the rotating rod, reducing the possibility of slipping.

[0021] In the above technical solution, further, the threads on the two bolts have the same direction of rotation and the same thread pitch, and the bolts are located in the limiting groove and are rotatably connected to the limiting groove.

[0022] In this technical solution, because the threads on the two bolts have the same direction of rotation and the same thread pitch, when the two bolts rotate in opposite directions, the two pressing blocks will be acted upon by the threads of the two bolts and move away from each other by the same distance or closer to each other along the two limiting grooves. At the same time, it ensures that when the bolts rotate, they can rotate normally within the limiting grooves.

[0023] Furthermore, the above technical solution also includes: Several second sliding grooves are respectively opened on the inner wall of several slots. Each of the several second sliding grooves is slidably connected with a plug rod, and one end of each plug rod passes through several plug blocks and extends into several plug blocks to engage with several plug blocks respectively. Two power components are located within the frame and are used to drive the movement of the corresponding two insert rods, respectively.

[0024] In this technical solution, users can secure the elastic bands to the frame, making it convenient for them to replace the two elastic bands.

[0025] In the above technical solution, the power component further includes: The movable groove is located within the frame and communicates with two second sliding grooves. A bidirectional threaded rod is rotatably connected within the movable groove, with both ends of the bidirectional threaded rod extending into the two second sliding grooves and passing through two insert rods, respectively, and threadedly connected to the two insert rods. A third bevel gear and a fourth bevel gear are rotatably connected within the movable groove, with the third bevel gear fixedly connected to the periphery of the bidirectional threaded rod. A rotating handle is fixedly connected to the fourth bevel gear, with one end of the rotating handle passing through the inner wall of the movable groove and extending to the outside, rotatably connected to the frame.

[0026] In this technical solution, it is ensured that the user can move the two plugs away from each other by the same distance or move them closer to each other by the same distance.

[0027] Compared with existing technologies, the beneficial effects of this invention for a dynamic pressure hemostasis device after cardiac pacemaker surgery are: 1. This dynamic pressure hemostasis device for post-cardiac pacemaker surgery, through its components including air bladders, connecting tubes, a small air pump, an exhaust pipe, a first small solenoid valve, a small pressure detector, a control panel, and a second small solenoid valve, allows the user to control the inflation or deflation of several air bladders. Simultaneously, it can monitor the detailed pressure within each air bladder. A first sliding groove and a sliding plate allow the user to control the lateral movement of the air bladders. Elastic bands, Velcro, and barbed Velcro allow the user to secure the dynamic pressure hemostasis device to the patient according to their chest circumference. This structural design allows the user to adjust the position of the dynamic pressure hemostasis device according to the location of the patient's wound, enabling rapid adaptation to the wound needs of different patients and surgeries. Ultimately, this improves the clinical versatility of the dynamic pressure hemostasis device and meets diverse hemostasis scenarios.

[0028] 2. This dynamic pressure hemostasis device for post-cardiac pacemaker surgery, through the use of bolts, connecting rods, a first bevel gear, a second bevel gear, and a rotating rod, allows the user to rotate two bolts in opposite directions. Through the setting of limiting grooves and bolts, when the two bolts rotate in opposite directions, the two compression blocks are pushed away from each other by the threads of the two bolts, compressing the inner wall of the first slide groove and fixing the slide plate within the first slide groove. With this structural design, when the slide plate moves several airbags to the appropriate position, the user can quickly fix the slide plate within the first slide groove, preventing it from moving. This allows the slide plate to be stably fixed within the first slide groove, ensuring that the several airbags are stably attached to the patient's wound.

[0029] 3. This dynamic pressure hemostasis device for post-cardiac pacemaker surgery, through the design of a threaded groove and a threaded sleeve, allows the threaded sleeve to move towards the slide plate under the action of the threaded groove, so that the threaded sleeve is tightly pressed against the slide plate, fixing the rotating rod in the gear groove and preventing it from rotating. With the above structure design, when the rotating rod rotates to the preset position, the user can fix the rotating rod in the gear groove and prevent it from rotating due to external influences, so that the slide plate can be fixed more stably.

[0030] 4. This dynamic pressure hemostasis device for post-cardiac pacemaker surgery allows users to replace two elastic bands through slots and inserts. A second slide, insert rod, bidirectional threaded rod, movable groove, third bevel gear, fourth bevel gear, and rotating handle allow users to disassemble or install several inserts. This design allows users to quickly replace the elastic bands, hook and loop fasteners, and barbed hook and loop fasteners when they fail after prolonged use, increasing the overall lifespan of the device.

[0038] The following examples further illustrate the present invention for a dynamic pressure hemostasis device after cardiac pacemaker surgery.

[0039] Example 1: Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, this embodiment provides a dynamic pressure hemostasis device for post-cardiac pacemaker surgery, comprising: The frame 1 and the first slide 2 are provided. The first slide 2 is opened inside the frame 1 and is connected to the outside. A slide plate 3 is slidably connected inside the first slide 2. Several airbags 4 are fixedly connected to one side of the slide plate 3. A connecting pipe 5 is fixedly connected between the several airbags 4, and the inner cavity of the connecting pipe 5 is connected to the inner cavity of the several airbags 4. A second small solenoid valve 34 is fixedly connected at the connection point between the connecting pipe 5 and the several airbags 4. A small air pump 6 is fixedly connected to the other side of the slide plate 3, and the output shaft of the small air pump 6 is fixedly connected to the connecting pipe 5. Several exhaust pipes 7 are fixedly connected to several airbags 4, and one end of several exhaust pipes 7 passes through one side of the slide plate 3 and extends to the other side of the slide plate 3. One end of several exhaust pipes 7 is fixedly connected to a first small solenoid valve 8, and a small pressure detector 9 is provided on several first small solenoid valves 8. Control panel 10 is fixedly connected to the other side of slide plate 3, and control panel 10 is electrically connected to small air pump 6, first small solenoid valve 8 and small pressure detector 9.

[0040] In some specific embodiments, the frame 1 can serve as the overall support structure for the device, and can be made of lightweight medical-grade ABS plastic, weighing ≤200g, combining strength and comfort to avoid pressure on the patient when wearing it. A first sliding groove 2, communicating with the outside, can be horizontally formed inside the frame 1. The width of the first sliding groove 2 can be 8-9mm, and the length is suitable for covering an adult chest wound range of 30-40cm. A sliding plate 3 can be slidably connected inside the first sliding groove 2. The sliding plate 3 can be made of medical-grade polycarbonate material, with a thickness of 5-8mm, and its sliding fit clearance can be ≤0.5mm to ensure smooth sliding without significant wobbling.

[0041] The slide plate 3 can be fixedly connected to 3-5 airbags 4 with medical adhesive on the side facing the wound. The airbags 4 can be made of medical silicone. The unfolded size of a single airbag 4 can be 50mm×30mm×10mm (length×width×height). It has good elasticity and biocompatibility and can avoid irritating the skin around the wound. Several airbags 4 can be evenly distributed along the length of the slide plate 3 (spacing 10-15mm). Adjacent airbags 4 can be fixedly connected by a connecting tube 5 made of medical PVC material. The inner diameter of the connecting tube 5 is 3-5mm. Its inner cavity is connected to the inner cavity of each airbag 4 to realize synchronous gas delivery and ensure that the pressure of all airbags 4 is consistent.

[0042] A small air pump 6 is fixedly connected to the side of the slide plate 3 away from the wound by screws. The small air pump 6 can be a miniature DC air pump with a rated voltage of 5V and a maximum inflation pressure of 0.05-0.1MPa, which meets the postoperative wound compression pressure requirements (the clinical routine hemostasis pressure is 0.03-0.08MPa). The output shaft of the small air pump 6 can be fixedly connected to the connecting pipe 5 through a quick connector, which can be quickly disassembled for maintenance. Several exhaust pipes 7 can be fixedly connected to the bottom of several airbags 4 by hot-melt welding. The exhaust pipes 7 can be medical PU tubes with an inner diameter of 2-3mm. One end of the exhaust pipe 7 can pass through one side of the slide plate 3 and extend to the other side of the slide plate 3. The extended end of the exhaust pipe 7 is connected to a first small solenoid valve 8 by thread. The first small solenoid valve 8 is normally closed and has a response time of ≤0.5s, which can quickly realize exhaust control. Several first small solenoid valves 8 are fixed with small pressure detectors 9 by clips. The measurement range of the small pressure detectors 9 is 0-0.2MPa and the accuracy is ±0.005MPa. It can collect the pressure data in the airbag 4 in real time.

[0043] The control panel 10 is fixedly connected to the side of the slide plate 3 away from the wound by a buckle. The control panel 10 measures 80mm×50mm×10mm and has a built-in STM32 microcontroller. The control panel 10 is electrically connected to the small air pump 6, the first small solenoid valve 8, and the small pressure detector 9 via wires. Its surface is equipped with an LCD display screen (30mm×20mm) and three physical buttons ("Inflate", "Exhaust", and "Pause"). The LCD display screen can display pressure data in real time (accuracy 0.001MPa), and the buttons can control the start and stop of the small air pump and the on / off control of the first small solenoid valve, which is convenient for medical staff to operate quickly.

[0044] The working process of this embodiment is as follows: When in use, medical staff can first fix the frame 1 to the patient's chest, and then push the slide plate 3 by hand so that the slide plate 3 can slide along the first slide groove 2 until several airbags 4 completely cover the patient's wound area; the small air pump 6 can be started by the "inflate" button of the control panel 10. The gas generated by the small air pump 6 can be injected into each airbag 4 synchronously through the connecting pipe 5. The airbags 4 inflate and can apply pressure to the wound; the small pressure detector 9 transmits the pressure data to the control panel 10 in real time, and the display screen dynamically displays the current pressure value. When the pressure reaches the preset hemostasis pressure (e.g., 0.05MPa), the "pause" button can be pressed to stop inflation; if the pressure exceeds the safety threshold (e.g., 0.08MPa), the "exhaust" button is pressed to start the first small solenoid valve 8. The gas in the airbag 4 can be discharged through the exhaust pipe 7 until the pressure drops to a reasonable range; after hemostasis is completed, the first small solenoid valve 8 can be kept open. After the airbags 4 are completely deflated, the slide plate 3 can be slid away from the wound to complete the operation.

[0045] Example 2: Please see Figure 3 , Figure 7 , Figure 8 As shown, this embodiment provides a dynamic pressure hemostasis device for post-cardiac pacemaker surgery. In addition to the technical solutions described in the above embodiments, it also has the following technical features, and further includes: Two limiting grooves 11 are formed in the slide plate 3 and connected to the first slide groove 2. Each of the two limiting grooves 11 is slidably connected to an extrusion block 12, and each of the two extrusion blocks 12 is threadedly connected to a bolt 13. The drive assembly is located inside the slide plate 3 and is used to drive the two bolts 13 to rotate.

[0046] In some specific embodiments, two limiting grooves 11 are formed in the slide plate 3 along a direction perpendicular to the first slide groove 2. The two limiting grooves 11 are symmetrically distributed on both sides of the slide plate 3 and are connected to the first slide groove 2. The cross-sectional dimensions of the limiting groove 11 are 15mm × 10mm (length × width). An extrusion block 12 is slidably connected in the groove. The extrusion block 12 is made of medical rubber and has anti-slip texture (texture depth 0.5mm) on its surface, which can increase the friction with the inner wall of the first slide groove 2. Both extrusion blocks 12 have internal threaded holes. Bolts 13 are connected to the internal threads of the threaded holes. The bolts 13 are made of medical stainless steel, with a length of 15-18mm and a thread specification of M6×1. The threads of the two bolts 13 have the same direction of rotation and the same pitch (1mm).

[0047] The slide plate 3 is equipped with a drive assembly for driving the two bolts 13 to rotate synchronously in opposite directions. The drive assembly includes two through slots 14: opened in the slide plate 3 and connected to two limiting slots 11 respectively. The diameter of the through slots 14 is 8mm. A connecting rod 15 is rotatably connected to it through a bearing. The connecting rod 15 is made of medical stainless steel and is 20-25mm long. One end of the connecting rod extends into the limiting slot 11 and is fixedly connected to the bolts 13 by welding, so as to ensure that the bolts 13 rotate synchronously when the connecting rod 15 rotates.

[0048] Gear groove 16: It is opened in the slide plate 3 and located between two through grooves 14. The groove size is 20mm×15mm×10mm (length×width×height). Two first bevel gears 17 are rotatably connected in the gear groove 16 through bearings. The first bevel gear 17 has a module of 1 and a number of teeth of 15. One end of the first bevel gear 17 extends into the through groove 14 and is fixedly connected to the other end of the connecting rod 15 by a key. A second bevel gear 18 meshes between the two first bevel gears 17. The module and number of teeth of the second bevel gear 18 are the same as those of the first bevel gear 17 to ensure smooth transmission. A rotating rod 19 is fixedly connected to the central shaft of the second bevel gear 18 by welding. The rotating rod 19 is made of medical stainless steel, with a diameter of 6mm and a length of 25-30mm. One end of the rotating rod penetrates the inner wall of the gear groove 16 and extends to the outside. The periphery of the extended end is provided with anti-slip texture (texture spacing 1mm) to facilitate hand grip and rotation.

[0049] The drive assembly also includes a fixing assembly to prevent the rotating rod 19 from rotating due to external vibration after locking. The fixing assembly includes a threaded groove 20 on the periphery of the rotating rod 19. The threaded groove 20 has a specification of M5×0.8 and a threaded sleeve 21 is threadedly connected to it. The threaded sleeve 21 is made of medical ABS plastic, with an outer diameter of 10mm and anti-slip texture (texture height 0.8mm) on its periphery to facilitate hand turning.

[0050] After the skateboard 3 slides to the target position, the medical staff holds the anti-slip end of the rotating rod 19 and rotates the rotating rod 19 clockwise. The rotating rod 19 drives the second bevel gear 18 to rotate in the gear groove 16. Since the second bevel gear 18 meshes with the two first bevel gears 17, the two first bevel gears 17 rotate synchronously in opposite directions (the left first bevel gear 18 rotates counterclockwise, and the right first bevel gear 18 rotates clockwise). The first bevel gears 17 drive the connecting rod 15 and the bolt 13 to rotate synchronously. Since the threads of the two bolts 13 have the same direction, when the bolts 13 rotate, they push the extrusion block 12 away from each other along the limiting groove 11 (left). (The side compression block 12 moves to the left, and the right compression block 12 moves to the right). When the anti-slip surface of the compression block 12 is tightly fitted with the inner wall of the first slide groove 2 and the slide plate 3 cannot move, stop rotating the rotating rod 19. Then rotate the threaded sleeve 21 clockwise, so that the threaded sleeve 21 moves along the threaded groove 20 towards the slide plate 3 until the end face of the threaded sleeve 21 is tightly pressed against the surface of the slide plate 3, thus fixing the position of the rotating rod 19. When it is necessary to adjust the position of the slide plate 3, rotate the threaded sleeve 21 counterclockwise to release the fixation, and then rotate the rotating rod 19 counterclockwise to make the compression blocks 12 move closer to each other and detach from the inner wall of the first slide groove 2, so that the slide plate 3 can slide. The synchronous reverse rotation of the bolt 13 is achieved through bevel gear transmission, ensuring that the compression block 12 is subjected to uniform force and avoiding unilateral displacement of the slide plate 3. The rubber material and anti-slip texture of the compression block 12 increase friction while avoiding damage to the inner wall of the first slide groove 2. The anti-loosening design of the threaded sleeve 21 can prevent the rotating rod 19 from loosening due to patient movement, ensuring stable compression position.

In addition to the technical solutions described in the above embodiments, it also has the following technical features: the driving component includes: Two through slots 14 are formed in the slide plate 3 and are respectively connected to two limiting slots 11. Each of the two through slots 14 is rotatably connected to a connecting rod 15, and one end of each connecting rod 15 extends into the two limiting slots 11 and is respectively fixedly connected to two bolts 13. Gear groove 16 is formed in the slide plate 3 and communicates with two through grooves 14. Two first bevel gears 17 are rotatably connected in the gear groove 16, and one end of each of the two first bevel gears 17 extends into the two through grooves 14 and is fixedly connected to the other end of each of the two connecting rods 15. A second bevel gear 18 meshes between the two first bevel gears 17. A rotating rod 19 is fixedly connected to the second bevel gear 18, and one end of the rotating rod 19 passes through the inner wall of the gear groove 16 and extends to the outside. A fixing component is located on the rotating rod 19 and is used to fix the rotating rod 19 in place.

[0052] In some specific embodiments, an elastic band 22 is provided on each of the left and right sides of the frame 1. The elastic band 22 is made of medical elastic knitted fabric, with a width of 25-30mm and a stretch ratio of 2:1, which can be adapted to patients of different body types (chest circumference 80-120cm). One of the elastic bands 22 has a loose hook and loop fastener 23 sewn to its free end. The size of the loose hook and loop fastener 23 is 70mm×40mm. The other elastic band 22 has a barbed hook and loop fastener 24 sewn to its free end. The size of the barbed hook and loop fastener 24 matches that of the loose hook and loop fastener 23. The two can be attached to each other to achieve detachable fixation. The peel strength after attachment is ≥5N / 25mm to ensure a firm fixation.

[0053] Two to three slots 25 are provided on each of the left and right sides of the frame 1. The cross-sectional dimensions of the slots 25 are 10mm × 8mm (length × width) and 15mm in depth. Several slots 25 are evenly distributed along the height direction of the frame 1 (20mm spacing), and the fixed position of the elastic band 22 can be adjusted according to the patient's chest height. Inserts 26 are inserted into each of the slots 25. The inserts 26 are made of medical PP plastic and are sized to match the slots 25 (10mm × 8mm × 15mm). One end of the insert 26 is fixedly connected to the non-free end of the elastic band 22 by a screw, so as to realize the detachable connection between the elastic band 22 and the frame 1.

[0054] The frame 1 is equipped with an auxiliary adjustment component for locking the plug 26, including: several second slide grooves 27: respectively opened on the upper and lower inner walls of several slots 25. The cross-sectional dimensions of the second slide groove 27 are 6mm×5mm (length×width). A plug rod 28 is slidably connected in the slide groove 27. The plug rod 28 is made of medical stainless steel, with a diameter of 5mm and a length of 20mm. One end of the plug rod 28 is chamfered (45° angle) to facilitate insertion into the plug 26. The upper and lower surfaces of the plug 26 are respectively opened with insertion holes that match the plug rod 28. One end of the plug rod 28 passes through the insertion hole of the plug 26 and extends into the plug 26, realizing the insertion and engagement of the plug 26 and the slot 25.

[0055] Two power components: located on the left and right sides of the frame 1 respectively, used to drive the corresponding two insertion rods 28 to move synchronously. Each power component includes: a movable groove 30: opened inside the frame 1 and connected to two second sliding grooves 27 on the same side. The movable groove 30 has dimensions of 30mm×15mm×10mm (length×width×height). A bidirectional threaded rod 29 is rotatably connected inside it through a bearing. The bidirectional threaded rod 29 is made of medical stainless steel, with a length of 25mm and a diameter of 6mm. The threads at both ends of the rod are opposite (right-hand thread on the left and left-hand thread on the right), with a thread specification of M6×1.

[0056] A third bevel gear 31 and a fourth bevel gear 32 are rotatably connected within the movable groove 30 via bearings. The third bevel gear 31 has a module of 1 and 12 teeth, and is fixedly connected to the middle of the bidirectional threaded rod 29 via a key. The fourth bevel gear 32 has the same module and number of teeth as the third bevel gear 31 and meshes with it. A rotating handle 33 is fixedly connected to the central shaft of the fourth bevel gear 32 via welding. The rotating handle 33 is made of medical ABS plastic, with a diameter of 10mm and a length of 30mm. One end of the handle penetrates the inner wall of the movable groove 30 and extends to the outside, and is rotatably connected to the frame 1 via bearings. The periphery of the extended end is provided with anti-slip texture (texture spacing 1.2mm) for easy hand grip.

[0057] The working process of this embodiment is as follows: When wearing the device, medical staff selects the slots 25 with fixed heights on both sides of the frame 1 according to the patient's chest height, and inserts the inserts 26 of the elastic band 22 into the slots 25; then, they hold the rotating handle 33 and rotate it clockwise. The handle drives the fourth bevel gear 32 to rotate, and the fourth bevel gear 32 meshes with and drives the third bevel gear 31 to rotate. The third bevel gear 31 drives the bidirectional threaded rod 29 to rotate in the movable groove 30. Since the threads at both ends of the bidirectional threaded rod 29 have opposite directions, the two inserts 28 move away from each other along the second sliding groove 27. The chamfered end of the 8 is inserted into the insertion hole of the insert 26 to fix the insert 26. Then, the frame 1 is placed in front of the patient's chest, and the two elastic bands 22 are wrapped around the patient's back and crossed, so that the barbed Velcro 24 and the loose Velcro 23 are attached. The attachment position is adjusted until the elastic band 22 is of moderate tightness (it is advisable to insert one finger). When the elastic band 22 needs to be replaced, the handle 33 is rotated counterclockwise, the bidirectional threaded rod 29 rotates in the opposite direction, and the insert rods 28 move closer to each other and disengage from the insert 26, so that the insert 26 and the old elastic band 22 can be pulled out. After replacing the new elastic band 22, the above fixing steps are repeated. The design of the multi-height slot 25 can adapt to the chest contours of different patients and improve wearing comfort; the detachable connection of the Velcro is convenient for quick wearing and removal; the cooperation of the insert rod 28 and the bidirectional threaded rod 29 achieves a stable fixation and convenient replacement of the elastic band 22, reducing the cost of consumables.

[0058] Example 4: Please see Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, this embodiment provides a dynamic pressure hemostasis device for post-cardiac pacemaker surgery. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the fixing components include: The threaded groove 20 is formed on the periphery of the rotating rod 19. A threaded sleeve 21 is threadedly connected to the threaded groove 20, and the periphery of the threaded sleeve 21 is provided with anti-slip texture.

[0059] In some specific embodiments, one end of the connecting rod 15 is rotatably connected to the inner wall of the limiting groove 11 via a deep groove ball bearing (bearing model 608ZZ) to ensure that the connecting rod 15 rotates without jamming; one end of the first bevel gear 17 is rotatably connected to the inner wall of the through groove 14 via a thrust ball bearing (bearing model 51105) to withstand axial force and prevent axial offset during bevel gear transmission; the second bevel gear 18 is rotatably connected to the inner wall of the gear groove 16 via a needle roller bearing (bearing model NA4902) to reduce rotational resistance; and the rotating rod 19 is rotatably connected to the inner wall of the gear groove 16 via a sliding bearing (bearing model HJ205) to ensure that the rotating rod 19 rotates smoothly without radial wobble.

[0060] The silicone material of the airbag 4 is infused with an antibacterial agent (silver ion concentration 0.1%), which has antibacterial function (antibacterial rate ≥99%) and can prevent wound infection; the interface between the connecting pipe 5 and the exhaust pipe 7 is made of ultrasonic welding process with a welding strength ≥10N to prevent gas leakage; the surface of the control panel 10 is covered with a waterproof membrane (IP67 protection level) to prevent sweat or disinfectant from entering and improve the durability of the equipment.

[0061] The control panel 10 has a built-in pressure alarm function. When the small pressure detector 9 detects that the pressure exceeds 0.1MPa (the upper limit of the safety threshold) or is lower than 0.03MPa (the lower limit of the effective hemostasis threshold), the display will flash and a buzzer will sound (volume ≥60dB) to remind medical staff to make timely adjustments. The small air pump 6 has a built-in overheat protection device. When the small air pump works continuously for more than 5 minutes or the temperature exceeds 60℃, it will automatically stop to avoid damage to the equipment.

[0062] During use in the above embodiments, each bearing component ensures smooth operation of rotating parts such as the rotating rod 19 and connecting rod 15, preventing pressure adjustment delays due to jamming; the antibacterial airbag 4 inhibits bacterial growth during compression, reducing the risk of wound infection; the waterproof control panel 10 can be wiped directly during clinical disinfection without worrying about damage; when the pressure is abnormal, the alarm function of the control panel 10 promptly alerts medical staff to handle the situation, and the overheat protection of the small air pump 6 prevents malfunctions caused by prolonged operation. The addition of bearing components improves the service life and stability of each rotating component; the antibacterial and waterproof design adapts to complex clinical environments; safety alarms and overheat protection further enhance the safety of the device and reduce medical risks.

[0063] Example 5: Please see Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 As shown, this embodiment provides a dynamic pressure hemostasis device for post-cardiac pacemaker surgery. In addition to the technical solutions described in the above embodiments, it also has the following technical features, and further includes: Two elastic bands 22 are provided on both sides of the frame 1. One end of one elastic band 22 is fixedly connected to a hook and loop fastener 23, and one end of the other elastic band 22 is fixedly connected to a barbed hook and loop fastener 24. The barbed hook and loop fastener 24 and the hook and loop fastener 23 are attached to each other. Several slots 25 are respectively opened on both sides of the frame 1, and each slot 25 has a plug 26 inserted into it, and each plug 26 is fixedly connected to the other end of two elastic bands 22.

[0064] In this process, the user peels the spiked Velcro 24 off the loose Velcro 23 by hand, then places the frame 1 in a suitable position on the patient's chest and wraps the two elastic bands 22 from the chest to the back by hand. Then, the user reattaches the spiked Velcro 24 to the first groove 2 of the loose Velcro 23 to ensure that the user can fix the frame 1 at any height on the user's chest.

[0065] Example 6: Please see Figure 7 , Figure 8 As shown, this embodiment provides a dynamic pressure hemostasis device for postoperative cardiac pacemaker surgery. In addition to the technical solution of the above embodiment, it also has the following technical features: one end of the connecting rod 15 is rotatably connected to the limiting groove 11, one end of the first bevel gear 17 is rotatably connected to the through groove 14, and the second bevel gear 18 is located in the gear groove 16 and is rotatably connected to the gear groove 16.

[0066] Specifically, it is ensured that when the connecting rod 15 rotates, one end of the connecting rod 15 can rotate normally within the limiting groove 11, and that when the first bevel gear 17 rotates, one end of the first bevel gear 17 can rotate normally within the through groove 14. At the same time, it is ensured that when the second bevel gear 18 rotates, the second bevel gear 18 can rotate normally within the gear groove 16.

[0067] Example 7: Please see Figure 7 , Figure 8 As shown, this embodiment provides a dynamic pressure hemostasis device for postoperative cardiac pacemaker surgery. In addition to the technical solution of the above embodiment, it also has the following technical features: the rotating rod 19 is located in the gear groove 16 and is rotatably connected to the first bevel gear 17 and the second bevel gear 18, and the circumference of the rotating rod 19 is provided with anti-slip texture.

[0068] Specifically, it is ensured that when the rotating rod 19 rotates, it can rotate normally within the gear groove 16. Furthermore, because the rotating rod 19 is provided with anti-slip texture on its periphery, when the user rotates the rotating rod 19 by hand, the anti-slip texture on the periphery of the rotating rod 19 will increase the friction of the rotating rod 19, reducing the possibility of slipping.

[0069] Example 8: Please see Figure 8 As shown, this embodiment provides a dynamic pressure hemostasis device for postoperative cardiac pacemaker surgery. In addition to the technical solution of the above embodiment, it also has the following technical features: the threads on the two bolts 13 have the same direction of rotation and the same thread pitch; the bolts 13 are located in the limiting groove 11 and are rotatably connected to the limiting groove 11.

[0070] Since the threads on the two bolts 13 have the same direction of rotation and the same thread pitch, when the two bolts 13 rotate in opposite directions, the two pressing blocks 12 will be acted upon by the threads of the two bolts 13 respectively, moving away from each other or closer to each other along the two limiting grooves 11 by the same distance. At the same time, this ensures that when the bolts 13 rotate, they can rotate normally within the limiting grooves 11.

[0071] Example 9: Please see Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 As shown, this embodiment provides a dynamic pressure hemostasis device for post-cardiac pacemaker surgery. In addition to the technical solutions described in the above embodiments, it also has the following technical features, and further includes: A plurality of second sliding grooves 27 are respectively opened on the inner wall of a plurality of slots 25. Each of the plurality of second sliding grooves 27 is slidably connected with a plug rod 28, and one end of each plug rod 28 passes through a plurality of plug blocks 26 and extends into the plurality of plug blocks 26 to engage with the plurality of plug blocks 26 respectively. Two power components are located within the frame 1 and are used to drive the corresponding two plug rods 28 to move respectively.

[0072] In use, the user drives the two insert rods 28 along the two second slide grooves 27, moving them away from or towards each other. When the two insert rods 28 move closer together, one end of each insert rod 28 enters the two second slide grooves 27 from the two insert blocks 26, releasing the fixation of the two insert blocks 26. When the fixation of the two insert blocks 26 is released, the user can replace the elastic band 22. When the two insert rods 28 move away from each other, one end of each insert rod 28 enters the two insert blocks 26 from the two second slide grooves 27, fixing the two insert blocks 26 in the two slots 25, ensuring that the user can fix the elastic band 22 to the frame 1, making it convenient for the user to replace the two elastic bands 22.

[0073] Example 10: Please see Figure 8 , Figure 9 , Figure 10 , Figure 11, Figure 12 , Figure 13 , Figure 14 As shown, this embodiment provides a dynamic pressure hemostasis device for post-cardiac pacemaker surgery. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the power component includes: The movable groove 30 is located within the frame 1 and is connected to two second sliding grooves 27. A bidirectional threaded rod 29 is rotatably connected within the movable groove 30, and both ends of the bidirectional threaded rod 29 extend into the two second sliding grooves 27 and pass through two insert rods 28, respectively, and are threadedly connected to the two insert rods 28. A third bevel gear 31 and a fourth bevel gear 32 are rotatably connected within the movable groove 30, and the third bevel gear 31 is fixedly connected to the periphery of the bidirectional threaded rod 29. A rotating handle 33 is fixedly connected to the fourth bevel gear 32, and one end of the rotating handle 33 passes through the inner wall of the movable groove 30 and extends to the outside, rotatably connecting to the frame 1.

[0074] In use, the user rotates the handle 33 by hand, causing the fourth bevel gear 32 to rotate within the movable groove 30. This causes the fourth bevel gear 32 to rotate the third bevel gear 31, which in turn causes the bidirectional threaded rod 29 to rotate within the movable groove 30. As the bidirectional threaded rod 29 rotates, the two insert rods 28 are respectively acted upon by the two sections of threads with opposite directions on the bidirectional threaded rod 29, causing them to move away from or towards each other along the two second sliding grooves 27. This ensures that the user can move the two insert rods 28 away from or towards each other by the same distance.

[0075] Working principle: In use, the user peels the barbed hook and loop fastener 24 off the loose hook and loop fastener 23 by hand. The user then places the frame 1 at a suitable position on the patient's chest and wraps the two elastic bands 22 from the chest to the back. The barbed hook and loop fastener 24 is then reattached to the first groove 2 of the loose hook and loop fastener 23, ensuring the frame 1 is fixed at any height on the user's chest. The user then slides the slide plate 3 along the first groove 2, causing it to move several airbags 4 to the patient's wound. The user then opens the corresponding second small solenoid valve 34 via the control panel 10, and then activates the small... Air pump 6 injects air into the corresponding airbag 4 through connecting pipe 5, allowing the corresponding airbag 4 to press on the patient's wound. At the same time, control panel 10 can detect the pressure data of several airbags 4 through several small pressure detectors 9. When not in use, the user can activate several first small solenoid valves 8 through control panel 10 to open the airbags 4 and discharge the air in the airbags 4 to the outside through several exhaust pipes 7 and several first small solenoid valves 8, ensuring that the user can adjust the position of the airbags 4 according to the position of the patient's wound. In use, the user manually rotates the rotating rod 19, causing the rotating rod 19 to drive the second bevel gear 18 to rotate within the gear groove 16. This causes the second bevel gear 18 to drive the two first bevel gears 17 to rotate in opposite directions. When the two first bevel gears 17 rotate in opposite directions, they will drive the two connecting rods 15 to rotate, causing the two connecting rods 15 to drive the two bolts 13 to rotate in opposite directions within the two compression blocks 12. When the two bolts 13 rotate in opposite directions, the two compression blocks 12 will be pushed away from each other along the two limiting grooves 11 by the threads of the two bolts 13. This causes the two compression blocks 12 to press against the inner wall of the first slide groove 2, fixing the slide plate 3 within the first slide groove 2 so that it cannot move. This ensures that several airbags 4 can be stably restricted at the patient's wound position. When in use, the user rotates the threaded sleeve 21 by hand, so that the threaded sleeve 21 moves towards the slide plate 3 under the action of the threaded groove 20, so that the threaded sleeve 21 is tightly pressed on the slide plate 3, and the rotating rod 19 is fixed in the gear groove 16, ensuring that the rotating rod 19 will not be affected by external factors and rotate. In use, the user manually rotates the handle 33, causing the fourth bevel gear 32 to rotate within the movable groove 30. This, in turn, drives the third bevel gear 31 to rotate, which in turn drives the bidirectional threaded rod 29 to rotate within the movable groove 30. As the bidirectional threaded rod 29 rotates, the two insert rods 28 are acted upon by the two oppositely oriented threads on the rod, causing them to move away from or towards each other along the two second sliding grooves 27. When the two insert rods 28 approach each other, the two insert rods 28... One end of the two rods 28 will enter the two second slide grooves 27 from the two inserts 26 respectively, releasing the fixation of the two inserts 26. When the fixation of the two inserts 26 is released, the user can replace the elastic band 22. When the two rods 28 move away from each other, one end of the two rods 28 will be inserted into the two inserts 26 from the two second slide grooves 27 respectively, fixing the two inserts 26 in the two slots 25 respectively, ensuring that the user can fix the elastic band 22 on the frame 1, making it convenient for the user to replace the two elastic bands 22.
