Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an integrated device for the reduction and fixation of traditional Chinese medicine bone injuries. Background Art

[0002] Traditional Chinese medicine has always focused on the reduction and fixation of fractures, dislocations and other injuries. In particular, in the treatment of arm or leg fractures, the traditional fixation method of splints and bandages is often used. This method uses multiple splints on the outside of the fracture site and fixes the splints to the patient's fracture site with bandages to achieve the purpose of correcting the bone position, limiting movement, and promoting fracture healing.

[0003] Although this method can achieve the initial fixation and correction of the fracture site to a certain extent, in the actual operation, the splint is prone to dislocation during the combination of the splint and the strap, especially at the end where the strap applies force, which often causes one end of the splint to be unstable and unable to maintain an accurate position, thus affecting the reduction effect of the fracture. This not only requires constant adjustment of the splint position, but may also have an adverse effect on the patient's recovery. Secondly, although the strap fixation method is simple and easy, in actual operation, the fixation and removal process often requires a lot of time and effort, especially when the splint position and strength need to be adjusted multiple times, the complexity of the operation is significantly increased, which increases the workload of medical staff.

[0004] Therefore, the present application provides an integrated device for reduction and fixation of bone injuries in traditional Chinese medicine to solve the above-mentioned problems. Summary of the invention

[0005] The present application provides an integrated device for reducing and fixing bone injuries in traditional Chinese medicine, aiming to solve the problems raised in the background art that the existing traditional Chinese medicine method for reducing and fixing bone injuries and fractures in the patient's arm or leg adopts a combination of a bandage and a splint for reduction and fixation, but when the splint is fixed by a bandage, it is easy to be dislocated, the fixation is not firm, and the operation is cumbersome.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a traditional Chinese medicine bone injury reduction and fixation integrated device, comprising two binding structures arranged opposite to each other and an adjustment structure arranged between the two binding structures for adjusting the docking angle of the two binding structures; In order to facilitate fine-tuning the joint of the fractured bones so that the two bones can be well docked together: the adjustment structure includes a movable ring fixedly set on one of the binding structures, a fixed ring sleeved on the movable ring and connected to the other binding structure, a transmission gear rotatably set on the fixed ring, a driven gear fixedly sleeved on the movable ring and meshingly connected to the transmission gear, and a driving member for driving the transmission gear to rotate. When in use, first fix the two binding structures on both sides of the fracture site respectively. Then, the transmission gear is driven to rotate by the driving member. Since the transmission gear is meshed with the driven gear, the driven gear will rotate therewith, and drive the movable ring and the binding structure connected thereto to rotate together. In this way, when one of the binding structures remains relatively still, the other binding structure can be adjusted circumferentially, thereby achieving fine-tuning misalignment between the two binding structures.

[0007] Preferably, the driving member includes a worm wheel rotatably arranged on the fixing ring and fixedly connected to the shaft of the transmission gear, and a worm screw arranged on the fixing ring and meshingly connected to the worm wheel, and a plum blossom plate is fixedly connected to the end of the worm screw. Through the combination of the worm wheel, the worm screw and the transmission gear, the precise fine-tuning of the docking angle of the fractured bone is achieved, which greatly improves the accuracy and effectiveness of the treatment. The self-locking characteristics of the worm wheel and the worm screw ensure the stability of the position after adjustment, and avoid fixation failure caused by patient activities or external forces. The design of the plum blossom plate allows medical staff to operate the driving member more conveniently, reduces the difficulty of operation, and improves work efficiency.

[0008] Preferably, in order to facilitate viewing the rotation angle of the other binding structure when one binding structure is relatively stationary: the movable ring is provided with an arc-shaped scale plate, and the fixed ring is fixedly provided with a pointer corresponding to the scale plate. Through the coordination of the arc-shaped scale plate and the pointer, medical staff can intuitively see the rotation angle between the two binding structures, which greatly improves the accuracy and operability of the adjustment. Accurate rotation angle control helps to avoid over-adjustment or under-adjustment, thereby reducing the treatment risk caused by improper operation.

[0009] Preferably, the binding structure includes a ring seat, a plurality of fixing plates arranged in an annular array on the inner ring of the ring seat, a threaded sleeve plate arranged inside the ring seat, and a threaded rod threadedly inserted into the threaded sleeve plate and rotatably connected to the fixing plate. Through the cooperation of the threaded rod and the threaded sleeve plate, medical staff can flexibly adjust the position of the fixing plate according to the patient's body shape and the specific conditions of the fracture site, ensuring that the binding structure can fit the patient's arm or leg tightly and reduce discomfort during the fixation process.

[0010] Preferably, in order to facilitate the connection between the ring seat and the fixed ring and the movable ring: a plurality of bearing plates are fixedly connected in an annular array on the ring seat, bolts are rotatably inserted on the bearing plates, and nuts for fixed connection with the movable ring and the outer wall of the fixed ring are threadedly sleeved on the bolts. Through the combination of the bearing plates, bolts and nuts, a stable connection between the ring seat and the fixed ring and the movable ring is achieved.

Through the combination of the strap and Velcro, the fixing plate is effectively fixed, displacement or looseness caused by unstable fixation during treatment is avoided, and the continuity and effectiveness of treatment are ensured.

[0013] Preferably, in order to facilitate the synchronous rotation of several threaded rods on the ring seat: the ring seat is provided with a synchronous member for driving several threaded rods to rotate synchronously, the synchronous member includes a first gear fixedly sleeved on the threaded sleeve plate and a second gear rotatably embedded in the end of the ring seat away from the adjustment structure, the second gear is meshed with the first gear, and the end of the second gear away from the ring seat is provided with a plurality of grooves for driving the second gear to rotate. The synchronous member also includes a limiting groove provided on the threaded rod, a limiting block provided in the limiting groove and fixedly connected to the ring seat. Through the meshing design of the first gear and the second gear, the synchronous driving of multiple threaded rods is realized, and the stability and reliability of the device are improved. The groove design on the second gear is convenient for medical staff to drive using tools, and the convenience and efficiency of operation are improved. Through the matching design of the limiting block and the limiting groove, the circumferential rotation of the threaded rod during the rotation process is effectively prevented, and the stability and reliability of the rotation of the threaded rod are ensured.

[0014] Through this fine-tuning mechanism, medical staff can precisely control the docking position of the fractured bones, ensuring that they fit tightly and promote healing. At the same time, since the entire adjustment process is simple, fast and easy to operate, it greatly improves the efficiency of treatment and the comfort of the patient.

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] This embodiment provides a traditional Chinese medicine bone injury reduction and fixation integrated device, such as Figure 1-6 As shown, the integrated device comprises two binding structures 1 arranged opposite to each other and an adjustment structure 2 arranged between the two binding structures 1 for adjusting the docking angle of the two binding structures 1; In order to facilitate fine-tuning the joint of the fractured bones so that the two bones can be well docked together: the adjustment structure 2 includes a movable ring 21 fixedly set on one of the binding structures 1, a fixed ring 22 sleeved on the movable ring 21 and connected to the other binding structure 1, a transmission gear 23 rotatably set on the fixed ring 22, a driven gear 24 fixedly sleeved on the movable ring 21 and meshed with the transmission gear 23, and a driving member 25 for driving the transmission gear 23 to rotate. Through the gear transmission mechanism in the adjustment structure 2, medical staff can accurately control the docking angle between the two binding structures 1, thereby ensuring that the fractured bones can be accurately docked. The driving member 25 adopts a manual knob design, which makes the entire adjustment process simple and fast, without the need for additional tools or equipment. The device can be personalized according to the body shape and fracture site of different patients, thereby improving the flexibility and effectiveness of treatment. When in use, first fix the two binding structures 1 on both sides of the fracture site respectively. Then, the driving member 25 drives the transmission gear 23 to rotate. Since the transmission gear 23 is meshed with the driven gear 24, the driven gear 24 will rotate accordingly, and drive the movable ring 21 and the binding structure 1 connected thereto to rotate together. In this way, when one binding structure 1 remains relatively still, the other binding structure 1 can be adjusted circumferentially, thereby achieving fine adjustment misalignment between the two binding structures 1.

[0019] Specifically, the driving member 25 includes a worm wheel 251 that is rotatably arranged on the fixing ring 22 and fixedly connected to the shaft of the transmission gear 23, and a worm 252 that is arranged on the fixing ring 22 and meshed with the worm wheel 251, and the end of the worm 252 is fixedly connected with a plum blossom plate 253. Through the combination of the worm wheel 251, the worm 252 and the transmission gear 23, the accurate fine adjustment of the docking angle of the fractured bone is achieved, which greatly improves the accuracy and effectiveness of the treatment. The self-locking characteristics of the worm wheel 251 and the worm 252 ensure the stability of the adjusted position and avoid the fixation failure caused by the patient's activities or external forces. The design of the plum blossom plate 253 allows medical staff to operate the driving member 25 more conveniently, reduces the difficulty of operation, and improves work efficiency. When in use, the medical staff first fixes the two binding structures 1 on both sides of the fracture site respectively. Then, by grabbing and rotating the plum blossom plate 253, the worm 252 is driven to rotate. The rotation of the worm 252 drives the worm wheel 251 to rotate in the same direction through the meshing relationship, and then drives the transmission gear 23 to rotate. Since the transmission gear 23 is meshed with the driven gear 24, the driven gear 24 will rotate accordingly, and drive the movable ring 21 and the binding structure 1 connected thereto to rotate together. In this way, when one of the binding structures 1 remains relatively still, the other binding structure 1 can be adjusted circumferentially, so as to achieve fine-tuning misalignment between the two binding structures 1.

[0020] Further, in order to facilitate viewing the rotation angle of the other binding structure 1 when one of the binding structures 1 is relatively stationary: an arc scale plate 211 is provided on the movable ring 21, and a pointer 221 corresponding to the scale plate 211 is fixedly provided on the fixed ring 22. Through the cooperation of the arc scale plate 211 and the pointer 221, medical staff can intuitively see the rotation angle between the two binding structures 1, which greatly improves the accuracy and operability of the adjustment. Accurate rotation angle control helps to avoid over-adjustment or under-adjustment, thereby reducing the treatment risk caused by improper operation. When in use, the medical staff first ensures that the two binding structures 1 are firmly fixed on both sides of the fracture site. Then, the driving member 25 (i.e., the combination of the worm wheel 251, the worm 252 and the plum blossom plate 253) is used to drive the transmission gear 23 to rotate. The rotation of the transmission gear 23 will drive the driven gear 24 and the movable ring 21 to rotate together. At this time, the arc scale plate 211 on the movable ring 21 will also rotate accordingly. Since the pointer 221 is fixed on the fixed ring 22 and its position remains unchanged, as the movable ring 21 rotates, the pointer 221 will point to different scale values ​​on the scale plate 211. The medical staff only needs to observe the scale value pointed by the pointer 221 to accurately know the current rotation angle between the two binding structures 1.

[0021] The binding structure 1 includes a ring seat 11, a plurality of fixing plates 12 arranged in an annular array on the inner circle of the ring seat 11, a threaded sleeve plate 13 arranged inside the ring seat 11, and a threaded rod 14 threadedly plugged into the threaded sleeve plate 13 and rotatably connected to the fixing plate 12. Through the cooperation of the threaded rod 14 and the threaded sleeve plate 13, medical staff can flexibly adjust the position of the fixing plate 12 according to the patient's body shape and the specific conditions of the fracture site, ensuring that the binding structure 1 can fit the patient's arm or leg tightly and reduce the discomfort during the fixation process. The threaded connection design of the threaded rod 14 and the threaded sleeve plate 13 makes the adjustment process simple and fast. Medical staff only need to rotate the threaded rod 14 to achieve fine adjustment of the position of the fixing plate 12, which greatly improves the convenience and efficiency of operation. The binding structure 1 can be personalized according to the body shape and fracture site of different patients, meeting the diverse needs in the treatment of bone injuries in traditional Chinese medicine. When in use, the medical staff first puts the device on the patient's arm or leg to ensure that the ring seat 11 is in close contact with the patient's skin or clothing. Then, the threaded rod 14 is rotated to move inward along the threaded hole of the threaded sleeve plate 13. As the threaded rod 14 moves, the fixing plate 12 gradually approaches the patient's arm or leg. When the fixing plate 12 contacts the patient's arm or leg, it means that the binding structure 1 has achieved a tight fixing effect. At this time, the medical staff can stop rotating the threaded rod 14 and fix the entire device on the patient's fracture site.

[0022] Specifically, in order to facilitate the connection between the ring seat 11 and the fixed ring 22 and the movable ring 21: a plurality of bearing plates 111 are fixedly connected in an annular array on the ring seat 11, a bolt 112 is rotatably inserted on the bearing plate 111, and a nut 113 for fixed connection with the outer wall of the movable ring 21 and the fixed ring 22 is threadedly sleeved on the bolt 112. Through the combination of the bearing plate 111, the bolt 112 and the nut 113, a stable connection between the ring seat 11 and the fixed ring 22 and the movable ring 21 is achieved. Due to the connection method of the bolt 112 and the nut 113, medical staff can easily disassemble and replace the parts of the binding structure 1 or the adjustment structure 2, which is convenient for cleaning, maintenance and upgrading. This connection method can be personalized according to the body shape and fracture site of different patients, ensuring the adaptability and flexibility of the device. The stable and easy-to-adjust connection method allows medical staff to complete the assembly and adjustment of the device more quickly and accurately, improving the efficiency of treatment and the comfort of patients. By rotating the nut 113 on the bolt 112 , the ring seat 11 is tightly fixed together with the outer walls of the fixed ring 22 and the movable ring 21 .

[0023] Furthermore, in order to improve the skin-friendliness between the fixing plate and the patient's arm or leg: a skin-friendly pad 122 is provided on the side of the fixing plate 12 away from the ring seat 11. The skin-friendly pad 122 is made of soft, breathable and skin-friendly materials, such as medical-grade silicone, memory foam or skin-friendly cloth. The selection of these materials not only ensures the softness and comfort of the skin-friendly pad 122, but also has good breathability and antibacterial properties, which helps to reduce the risk of skin irritation and infection.

[0024] Among them, in order to facilitate the fixing of the end of the fixing plate 12 away from the ring seat 11: the end of the fixing plate 12 away from the ring seat 11 is fixedly connected with a strap 121, the side of the strap 121 close to the fixing plate 12 is provided with a Velcro hook surface 1211, and the side of the strap 121 away from the fixing plate 12 is provided with a Velcro fur surface 1212. Through the combination of the strap 121 and the Velcro, the fixing plate 12 is effectively fixed, and the displacement or loosening caused by unstable fixation during the treatment process is avoided, ensuring the continuity and effectiveness of the treatment. The design of the Velcro makes the fixing and removal of the strap 121 simple and quick, and the medical staff can easily complete the fixing and adjustment work, improving the work efficiency. This fixing method can be personalized according to the body shape and fracture site of different patients, ensuring the adaptability and flexibility of the device. When in use, the medical staff will pass the strap 121 around the outside of several fixing plates 12 to ensure that the strap 121 can fit the patient's arm or leg tightly. Finally, the fixing plate 12 is firmly fixed to the patient's arm or leg through the bonding of the Velcro hook surface 1211 and the Velcro fleece surface 1212. During the fixing process, the medical staff can adjust the tightness of the strap 121 and the position of the fixing plate 12 according to the patient's body shape and the specific situation of the fracture site to ensure the stability and comfort of the fixation.

[0025] Furthermore, in order to facilitate the synchronous rotation of the plurality of threaded rods 14 on the ring seat 11: a synchronous member 3 for driving the plurality of threaded rods 14 to rotate synchronously is provided on the ring seat 11, and the synchronous member 3 includes a first gear 31 fixedly sleeved on the threaded sleeve 13 and a second gear 32 rotatably embedded in the end of the ring seat 11 away from the adjustment structure 2, the second gear 32 is meshed with the first gear 31, and a plurality of grooves 33 for driving the second gear 32 to rotate are provided in a ring shape at the end of the second gear 32 away from the ring seat 11. The synchronous member 3 also includes a limiting groove 34 provided on the threaded rod 14, and a limiting block 35 provided in the limiting groove 34 and fixedly connected to the ring seat 11. Through the meshing design of the first gear 31 and the second gear 32, the synchronous driving of the plurality of threaded rods 14 is realized, and the stability and reliability of the device are improved. The groove 33 design on the second gear 32 is convenient for medical staff to drive using tools, and improves the convenience and efficiency of operation. The matching design of the stop block 35 and the stop groove 34 effectively prevents the threaded rod 14 from rotating in the circumferential direction during the rotation process, ensuring the stability and reliability of the rotation of the threaded rod 14. The design of the synchronizer 3 can be adjusted according to the body shape and fracture site of different patients, ensuring the adaptability and flexibility of the device. When in use, the medical staff inserts a tool (such as a wrench or a screwdriver) into the groove 33 on the second gear 32 and drives the second gear 32 to rotate. Since the second gear 32 is meshed with the first gear 31, when the second gear 32 rotates, it will drive the first gear 31 to rotate synchronously, thereby driving the threaded sleeve 13 and the threaded rod 14 connected thereto to rotate together. During the rotation of the threaded rod 14, due to the matching design of the stop block 35 and the stop groove 34, the circumferential movement of the threaded rod 14 is limited, and it can only move along the thread direction of the threaded sleeve 13. In this way, as the threaded rod 14 rotates and moves, the fixing plate 12 will gradually approach the patient's arm or leg until it stops when it conflicts with the patient's arm or leg.

[0026] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
