Description

Technical Field

[0001] This invention relates to the field of cardiac postoperative rehabilitation technology, and in particular to a postoperative rehabilitation device and method for cardiac pacemakers. Background Technology

[0002] Currently, during cardiac pacemaker surgery, the pacemaker electrode leads need to be implanted and fixed to the myocardial tissue via a vein. The first 1-2 weeks post-surgery are a critical window for electrode and myocardial anchoring and healing. During this period, if the operated arm is raised, abducted, or subjected to sudden force, it can easily lead to electrode displacement, lead traction, or even dislodgement. This can not only cause abnormal pacemaker pacing function but also lead to complications such as pocket hemorrhage and local hematoma. In severe cases, interventional surgery may be required for adjustment, significantly increasing the patient's physical and mental burden and medical costs. Therefore, patients' arms cannot move extensively and need to wear a movement restriction device to fix the arm and avoid excessive movement that could affect the post-cardiac pacemaker recovery.

[0003] In the aforementioned existing technologies, when restricting the arm, most methods use an integrated fixing sleeve or a simple strap structure to restrict arm movement. This can only meet basic restraint requirements and cannot flexibly adjust the restriction angle and range of motion according to the patient's rehabilitation progress. This is very inconvenient for patients to use and may also lead to health problems such as muscle atrophy and joint stiffness due to prolonged restriction of the patient's arm. Summary of the Invention

[0004] The purpose of this invention is to provide a postoperative rehabilitation device and method for cardiac pacemakers, which solves the problem that in the prior art, when restricting the arm, most of them use an integrated fixing sleeve or simple bandage structure to achieve arm movement restriction. This can only meet the basic constraint requirements and cannot flexibly adjust the restriction angle and range of motion according to the patient's rehabilitation progress. This is very inconvenient for patients to use and may also lead to health problems such as muscle atrophy and joint stiffness due to prolonged restriction of the patient's arm.

The lifting cylinder has multiple second threaded holes, and the lifting and limiting screws are adapted to each other. The lifting rod is slidably connected to the lifting cylinder.

[0010] The limiting component further includes a housing, two support adjustment mechanisms, and an internal linkage unit. The housing is disposed on the outer wall of the belt. The two support adjustment mechanisms are symmetrically disposed on one side of the housing. An angle moving block is disposed between the two support adjustment mechanisms. The internal linkage unit is disposed inside the housing. The angle adjustment bar is disposed on the internal linkage unit.

[0011] The support adjustment mechanism includes two grooves, two spheres, and an external telescopic rod. The two grooves are respectively disposed on the angle moving block and the outer shell. The two spheres are respectively disposed inside the corresponding grooves. The spheres are clearance-fitted with the grooves. The two ends of the external telescopic rod are respectively fixedly connected to the corresponding spheres. The angle connecting block is rotatably connected to the grooves on both sides.

[0012] The internal linkage unit includes two support rings, a take-up and release shaft, two gear rings, a gear, a rack, a threaded block, an internal threaded rod, an internal telescopic rod, and a drive handle. Both support rings are fixedly connected to the interior of the outer casing. The two support rings are rotatably connected to both ends of the take-up and release shaft.

The height of the lifting rod is adjusted by the lifting limit unit. Pulling the angle moving block laterally causes the angle take-up and unwind strip to unwind, increasing the movable range of the limiting cylinder; Once the appropriate range is reached, the angle of the extension and retraction bar is limited by the limiting rod. After a period of use and rehabilitation, the patient's arm range of motion increases. At this point, the limiting rod is pulled out, and the angle extension bar and the lifting rod are pulled out to adjust the range of motion of the limiting cylinder.

[0015] This invention discloses a postoperative rehabilitation device and method for cardiac pacemakers. The patient wears the waist belt around their waist, while simultaneously placing their left upper arm inside the limiting cylinder. The height of the lifting rod is adjusted via the lifting and limiting unit. The angle moving block is pulled laterally, causing the angle release bar to unwind, increasing the movable range of the limiting cylinder. Once a suitable range is reached, the angle release bar is restricted by the limiting rod. After a period of use and rehabilitation, the patient's arm's range of motion increases. At this point, the limiting rod is removed, and the angle release bar and the lifting rod are pulled out further, adjusting the movable range of the limiting cylinder. The range of motion is greatly expanded. By placing the patient's arm into the limiting cylinder, the height of the limiting cylinder is adjusted by the extension and retraction of the lifting rod. At the same time, the arm's extension angle is adjusted by the retraction and retraction of the angle extension bar. Finally, with the rotation of the angle connecting block and the lifting rod, complex movements of arm rotation, forward extension, and backward swing are supported. While limiting the range of arm movement, the range of arm movement is preserved as much as possible. As the user further recovers, the range of movement is gradually expanded until the arm is completely free from the limiting cylinder. Compared with traditional fixation sleeves and fixation straps, this significantly improves the rehabilitation effect. Attached Figure Description

Detailed Implementation

[0029] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0030] Please see Figures 1 to 10 The present invention provides a postoperative rehabilitation device for a cardiac pacemaker, comprising a waist belt 36, a limiting cylinder 37 and a limiting assembly, wherein the limiting cylinder 37 is disposed on one side of the waist belt 36; The limiting assembly includes a lifting rod 1, a lifting limiting unit, an angle moving block 2, an angle retractable strip 3, and a limiting rod 4. The angle retractable strip 3 has multiple limiting grooves 5. The angle retractable strip 3 is disposed on one side of the waist belt 36. The angle moving block 2 is disposed at one end of the angle retractable strip 3. The limiting rod 4 is disposed above the angle retractable strip 3. The limiting rod 4 and the limiting grooves 5 are mutually adapted. The lifting limiting unit is disposed on one side of the angle moving block 2. The lifting rod 1 is disposed inside the lifting limiting unit. The limiting cylinder 37 is rotatably connected to one end of the lifting rod 1.

[0031] In this embodiment, the patient wears the waist belt 36 around their waist, while simultaneously placing their left upper arm inside the limiting cylinder 37; the height of the lifting rod 1 is adjusted via the lifting and limiting unit; the angle moving block 2 is pulled laterally to unwind the angle winding strip 3, increasing the movable range of the limiting cylinder 37; once a suitable range is reached, the angle winding strip 3 is restricted by the limiting rod 4; after a period of use and rehabilitation, the patient's arm's range of motion increases, at which point the limiting rod 4 is pulled out, and the angle winding strip 3 and the lifting rod 1 are pulled out again to adjust the movable range of the limiting cylinder 37; Therefore, by placing the patient's arm into the limiting cylinder 37, the height of the limiting cylinder 37 can be adjusted by the extension and retraction of the lifting rod 1. At the same time, the arm's extension angle can be adjusted by the retraction and retraction of the angle extension bar 3. Finally, with the rotation of the angle connecting block and the lifting rod 1, complex movements of arm rotation, forward extension, and backward swing can be supported. While restricting the range of arm movement, the range of arm movement can be preserved as much as possible. As the user further recovers, the range of movement can be gradually expanded until the arm is completely free from the limiting cylinder 37. Compared with traditional fixation sleeves and fixation straps, this significantly improves the rehabilitation effect.

[0032] Furthermore, the limiting component also includes an arm fixing unit, which is disposed on the limiting cylinder 37; The arm fixing unit includes a fixing cover 6, two pressing mechanisms and a quick-release mechanism. One side of the fixing cover 6 is rotatably connected to the limiting cylinder 37. The two pressing mechanisms are sequentially arranged on the fixing cover 6, and the quick-release mechanism is arranged on the other side of the fixing cover 6.

[0033] In this embodiment, the fixing cover 6 covers the outside of the limiting cylinder 37 through the quick-release mechanism, wrapping the patient's arm inside, and then the internal space is contracted by the pressing mechanism to achieve a firm effect, prevent loosening, and adapt to different patients' arm circumferences.

[0034] Furthermore, the pressing mechanism includes a pressing screw 7 and a pressing plate 8, the fixing cover 6 has a first threaded hole 9, the pressing screw 7 is adapted to the first threaded hole 9, and one end of the pressing screw 7 is fixedly connected to the pressing plate 8.

[0035] In this embodiment, the pressing screw 7 is rotated to engage with the first threaded hole 9, thereby gradually moving the pressing screw 7 into the restricting cylinder 37, so that the pressing plate 8 contacts the patient's upper arm, achieving the effect of fixing the restricting cylinder 37.

[0036] Furthermore, the quick-release mechanism includes a locking block 10, an inclined block 11, and a locking spring 12. The limiting cylinder 37 has a groove 13, the locking block 10 is adapted to the groove 13, the locking block 10 has a slot 14, the locking block 10 is disposed on the other side of the fixing cover 6, the inclined block 11 is slidably connected to the groove 13, and the two ends of the locking spring 12 are respectively movably connected to the inner wall of the groove 13 and the inclined block 11.

[0037] In this embodiment, when fixing the fixing cover 6, after placing the patient's upper arm inside the limiting cylinder 37, the fixing cover 6 is directly closed. At this time, the locking block 10 is inserted into the groove 13 and contacts the inclined surface of the inclined block 11, pushing it to retract. Finally, the locking spring 12 drives the inclined block 11 to rebound, causing it to enter the slot 14 of the locking block 10, thus limiting the fixing cover 6. When it is necessary to remove the arm, the inclined block 11 is pulled from outside the limiting cylinder 37 to disengage it from the slot 14, and then the fixing cover 6 can be rotated to open.

[0038] Furthermore, the lifting and limiting unit includes a lifting cylinder 15, a lifting and limiting block 16, and a plurality of lifting and limiting screws 17. The lifting cylinder 15 is disposed on one side of the angle moving block 2, the lifting and limiting block 16 is disposed on one side of the lifting rod 1, the lifting cylinder 15 has a plurality of second threaded holes 18, the lifting and limiting screws 17 are adapted to the second threaded holes 18, and the lifting rod 1 is slidably connected to the lifting cylinder 15.

[0039] In this embodiment, the lifting cylinder 15 supports the lifting rod 1. When limiting the minimum range of motion of the lifting rod 1: the lowest lifting limit screw 17 is screwed into the lifting cylinder 15. When the lifting rod 1 is pulled out by the limiting cylinder 37, the lifting limiting block 16 contacts and is blocked by the lowest lifting limit screw 17. By screwing in the corresponding upper lifting limit screws 17 in sequence, different ranges of motion can be limited. In addition, the lifting rod 1 and the limiting cylinder 37 are rotatable, preserving the patient's need for rotation between the forearm and upper arm.

[0040] Furthermore, the limiting component also includes a housing 19, two support adjustment mechanisms, and an internal linkage unit. The housing 19 is disposed on the outer wall of the waist belt 36. The two support adjustment mechanisms are symmetrically disposed on one side of the housing 19. The angle moving block 2 is disposed between the two support adjustment mechanisms. The internal linkage unit is disposed inside the housing 19. The angle extension / retraction bar 3 is disposed on the internal linkage unit.

[0041] In this embodiment, the outer shell 19 supports the internal components, the support adjustment mechanism supports the angle moving block 2 to improve its stability during angle adjustment, and the internal linkage unit is used to automatically limit the angle retractable bar 3 after it reaches the activity limit range when the angle retractable bar 3 is pulled out.

[0042] Furthermore, the support adjustment mechanism includes two grooves 20, two balls 21, and an external telescopic rod 22. The two grooves 20 are respectively disposed on the angle moving block 2 and the outer shell 19. The two balls 21 are respectively disposed inside the corresponding grooves 20. The balls 21 are clearance-fitted with the grooves 20. The two ends of the external telescopic rod 22 are respectively fixedly connected to the corresponding balls 21. The angle connecting block is rotatably connected to the grooves 20 on both sides.

[0043] In this embodiment, the groove 20 limits the movement of the ball 21, allowing the ball 21 to rotate freely within the groove 20. As the angle connecting block moves, it drives the groove 20 to move, ultimately causing the groove 20 to move and the ball 21 to move. The ball 21 then drives the external telescopic rod 22 to extend and retract. The external telescopic rod 22 is a damping buffer rod, which improves the stability of the adjustment and prevents the angle extension bar 3 from moving in four directions due to the lack of any connection between the angle connecting block and the outer shell 19.

[0044] Furthermore, the internal linkage unit includes two support rings 23, a take-up and release shaft 24, two gear rings 25, a gear 26, a rack 27, a threaded block 28, an internal threaded rod 29, an internal telescopic rod 30, and a drive handle 31. Both support rings 23 are fixedly connected to the interior of the outer casing 19. The two support rings 23 are rotatably connected to both ends of the take-up and release shaft 24. The other end of the angle take-up and release bar 3 is wound around the outside of the take-up and release shaft 24. The two gear rings 25 are sequentially sleeved on the outside of the take-up and release shaft 24. The gear 26... The rack 27 meshes with the gear 26 and the two gear rings 25. The threaded block 28 is disposed on one side of the rack 27. The internal threaded rod 29 is adapted to the threaded block 28. The limiting rod 4 is disposed below the internal threaded rod 29. The drive handle 31 is rotatably connected to the outer shell 19. The two ends of the internal telescopic rod 30 are fixedly connected to the drive handle 31 and the internal threaded rod 29, respectively. The two ends of the take-up and release shaft 24 are respectively provided with fastening screws 32 and take-up handles 33.

[0045] In this embodiment, the support ring 23 supports the retractable shaft 24. When the patient's upper arm moves, the lifting cylinder 15 is driven by the limiting cylinder 37, and finally the lifting cylinder 15 drives the angle retractable bar 3 to extend. Subsequently, the angle retractable bar 3 drives the retractable shaft 24 to unwind. When the retractable shaft 24 unwinds, it drives the gear ring 25 to rotate. The gear ring 25 drives the gear 26 to rotate. The gear 26 drives the rack 27 to move downward. At this time, the threaded block 28 and the internal threaded rod 29 on the rack 27 move downward, so that the limiting rod 4 on the internal threaded rod 29 inserts into the angle retractable bar. The limiting groove 5 of the release bar 3 achieves a limiting effect; when it is necessary to adjust the different limiting positions of the angle release bar 3, the drive handle 31 needs to be rotated from the outside of the outer shell 19 to drive the internal telescopic rod 30 to rotate, causing the internal threaded rod 29 to rotate, thereby adjusting the height of the internal threaded rod 29 and the limiting rod 4. After adjusting the height upward, pulling the angle release bar 3 will increase the downward distance of the limiting rod 4, thereby delaying the time when the limiting rod 4 restricts the angle release bar 3, that is, increasing the range of motion; conversely, adjusting the height of the internal threaded rod 29 downward will reduce the range of motion. In addition, after the angle take-up bar 3 is limited by the limiting rod 4, the fastening screw 32 can be rotated to reinforce the take-up shaft 24; when it is necessary to rewind the angle take-up bar 3, the take-up throttle 33 can be rotated to drive the take-up shaft to rotate for the take-up operation.

[0046] Furthermore, the internal linkage unit also includes two auxiliary wheels 34 and two internal stabilizing rods 35. The two auxiliary wheels 34 are respectively disposed on both sides of the angle extension bar 3. One end of each of the two internal stabilizing rods 35 is fixedly connected to the inner top wall of the outer shell 19, and the other end of each of the two internal stabilizing rods 35 is fixedly connected to the rack 27.

[0047] In this embodiment, the auxiliary wheel 34 limits the angle connecting shaft to prevent it from swaying up and down and improves the stability of winding and unwinding. The internal stabilizing rod 35 limits the up and down movement of the rack 27 and improves the stability of movement.

[0048] When using a postoperative rehabilitation device for a cardiac pacemaker according to this embodiment, the patient wears the waist belt 36 around their waist, while simultaneously placing their left upper arm inside the limiting cylinder 37; the height of the lifting rod 1 is adjusted via the lifting and limiting unit; the angle moving block 2 is pulled laterally to unwind the angle retraction bar 3, increasing the movable range of the limiting cylinder 37; once a suitable range is reached, the angle retraction bar 3 is restricted by the limiting rod 4; after a period of use and rehabilitation, the patient's arm's range of motion increases, at which point the limiting rod 4 is pulled out, and the angle retraction bar 3 and the lifting rod 1 are pulled out further, adjusting the limiting cylinder. 37. Range of motion: Thus, by placing the patient's arm into the limiting cylinder 37, the height of the limiting cylinder 37 can be adjusted by the extension and retraction of the lifting rod 1. At the same time, the arm's extension angle can be adjusted by the retraction and retraction of the angle extension bar 3. Finally, in conjunction with the rotation of the angle connecting block and the lifting rod 1, complex movements of arm rotation, forward extension, and backward swing can be supported. While limiting the range of arm movement, the range of arm movement is preserved as much as possible. As the user further recovers, the range of movement is gradually expanded until the arm is completely free from the limiting cylinder 37. Compared with traditional fixation sleeves and fixation straps, this significantly improves the rehabilitation effect.

[0049] Please see Figure 11 The present invention also provides a postoperative rehabilitation method for cardiac pacemakers, comprising the following steps: S1: The patient wears the waist belt 36 around his waist, while his left upper arm is placed inside the limiting tube 37; S2: Adjust the height of the lifting rod 1 using the lifting limit unit; S3: Pull the angle moving block 2 laterally to unwind the angle take-up and unwind strip 3, thereby increasing the movable range of the limiting cylinder 37; S4: After reaching the appropriate range, the angle extension bar 3 is restricted by the limiting rod 4; S5: After a period of use and rehabilitation, the range of motion of the patient's arm increases. At this time, pull out the limiting rod 4, continue to pull out the angle extension bar 3 and the lifting rod 1, and adjust the range of motion of the limiting cylinder 37.

[0050] The patient wears the waist belt 36 around their waist, while simultaneously placing their left upper arm inside the limiting cylinder 37. The height of the lifting rod 1 is adjusted using the lifting and limiting unit. The angle moving block 2 is pulled laterally to unwind the angle winding strip 3, increasing the movable range of the limiting cylinder 37. Once a suitable range is reached, the angle winding strip 3 is restricted by the limiting rod 4. After a period of use and rehabilitation, the patient's arm's range of motion increases. At this point, the limiting rod 4 is removed, and the angle winding strip 3 and the lifting rod 1 are pulled out to adjust the movable range of the limiting cylinder 37.

[0051] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
