Abstract
Description
Technical Field
[0001] This utility model relates to the field of skeletal assistive tools, and in particular to a skeletal assistive external wearing tool for stabilizing bones. Background Technology
[0002] With the development of medical technology, science and medicine are becoming increasingly integrated. When people suffer bone injuries due to external impacts, they need timely medical treatment to help the bones recover, thereby eliminating or reducing functional impairments, restoring their ability to live and work to the greatest extent possible, and returning to society and family.
[0003] Currently, existing bone-assisted external penetrating tools, such as the patent document with publication number CN216021437U, disclose an auxiliary support device for orthopedic care. By fixing a sterilization box between the storage slots, the orthopedic care tools can be classified and stored using storage racks. Then, the ultraviolet light emitted by the mercury lamp installed inside the sterilization lamp is used to sterilize and disinfect the orthopedic care tools, which can prevent cross-infection of the orthopedic care tools. Finally, the sterilization box is sealed with a door to prevent ultraviolet light from escaping and affecting the health of orthopedic patients and medical staff.
[0004] However, during the implementation of the above technical solutions, at least the following technical problems were found: different people have different bone sizes and need to use different fixation clamps. Most of the fixation clamps currently in use adopt a rigid connection state. Especially when dealing with bones in a bent state, since bones in a bent state may need a certain range of motion, the rigid connection fixation clamps cannot provide this flexibility, thus reducing the scope of use. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a stabilizing bone-assisted external penetrating tool, solving the problem that most widely used fixation clamps are rigidly connected, especially when dealing with bones in a bent state. Since bones in a bent state may require a certain range of motion, rigidly connected fixation clamps cannot provide this flexibility, thus limiting their application range.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A skeletal stabilizing external piercing tool includes a first splint and a second splint. Two connecting seats are fixedly installed on the side end of the second splint. A first support rod is fixedly installed on the side end of each connecting seat. The top ends of the two first support rods are slidably mounted with the same first connecting plate. Two second support rods are provided on the side end of each second splint. A second connecting plate is fixedly installed on the top ends of the two second support rods. A cushioning pad is fixedly installed inside each second splint.
[0010] Preferably: a ball head is fixedly installed on the side end of each second support rod; two rotating buckles are rotatably installed on the outer side of each first clamping plate; two threaded rods are rotatably installed on the bottom end of each first clamping plate; a bevel gear is fixedly installed on the top end of each threaded rod; a telescopic rod is fixedly installed on the side end of each first connecting plate; an L-shaped plate is fixedly installed on the top end of each telescopic rod; a fixing rod is fixedly installed on the side end of each L-shaped plate; a positioning ring is fixedly installed at the end of each fixing rod; and at least two grooves are formed on the side end of each first support rod.
[0011] (III) Beneficial Effects
[0012] 1. The positioning ring is driven by the fixed rod to slide inside the first connecting plate and the second connecting plate. The first connecting plate and the second connecting plate rotate relative to each other and are connected by rotation. The rotating shaft inside the second connecting plate and the side end of the first connecting plate are both provided with slots. By moving the positioning ring, the positioning state of the first connecting plate and the second connecting plate is released. At the same time, the end of the L-shaped plate leaves the inside of the first support rod, allowing the first connecting plate to slide on the side end of the first support rod. The first connecting plate and the second connecting plate can also rotate, allowing the angle of the two sets of first clamping plates and second clamping plates to be adjusted, increasing the range of use.
[0013] 2. By driving the threaded rod to rotate at the bottom end of the first splint, and at the same time, the end of the threaded rod to rotate at the top end of the second splint, the distance between the first and second splints is controlled by the rotating threaded rod, so as to clamp and fix bones of different sizes. At the same time, buffer pads are installed on the inner side of both the first and second splints. The buffer pads play a separating role and reduce the discomfort of the first and second splints when fixing the patient's bones. Attached Figure Description

[0020] This application provides a sturdy bone-assisted external penetrating tool, effectively solving the problem that most widely used fixation clamps are rigidly connected, especially when dealing with bent bones. Bending bones may require a certain range of motion, which rigidly connected clamps cannot provide, thus limiting their usability. The tool uses a fixing rod to drive a positioning ring to slide inside the first and second connecting plates. The first and second connecting plates rotate relative to each other and are connected by rotation. The rotating shaft inside the second connecting plate and the side end of the first connecting plate both have slots. By moving the positioning ring, the positioning state of the first and second connecting plates is released, and the end of the L-shaped plate moves away from the inside of the first support rod, allowing the first connecting plate to slide on the side end of the first support rod. The first and second connecting plates can also rotate, allowing the angles of the two sets of first and second clamps to be adjusted, increasing the usability.
[0021] Example
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application effectively solves the problem that most widely used fixation clamps are rigidly connected, especially when dealing with bones in a bent state. Since bones in a bent state may require a certain range of motion, rigidly connected fixation clamps cannot provide this flexibility, thus limiting their application range. The overall idea is as follows:
[0023] To address the problems existing in the prior art, this utility model provides a stabilizing bone-assisted external penetrating tool, including a first clamp 11 and a second clamp 12. Two connecting seats 13 are fixedly installed on the side end of the second clamp 12. A first support rod 14 is fixedly installed on the side end of each connecting seat 13. The top ends of the two first support rods 14 are slidably installed with the same first connecting plate 15. Two second support rods 27 are provided on the side end of each second clamp 12. A second connecting plate 22 is fixedly installed on the top ends of the two second support rods 27. A buffer pad 26 is fixedly installed inside each second clamp 12. A ball head 21 is installed at one end of the first support rod 14 and the L-shaped plate 17. One side of the ball head 21 is hemispherical and is connected to the inside of the connecting seat 13 in a ball cage manner, which can be deflected and rotated to facilitate adjustment of the angle between the two first clamps 11 and the second clamp 12. By rotating the rotating buckle 23, the rotating buckle 23 is rotated on the outside of the first clamp 11. At the same time, the end of the rotating buckle 23 is rotatably connected to the threaded rod 25.
[0024] Each second support rod 27 has a ball head 21 fixedly installed on its side end. Each first clamping plate 11 has two rotating buckles 23 rotatably installed on its outer side. Each first clamping plate 11 has two threaded rods 25 rotatably installed on its bottom end. Each threaded rod 25 has a bevel gear 24 fixedly installed at its top end. Each first connecting plate 15 has a telescopic rod 16 fixedly installed on its side end. Each telescopic rod 16 has an L-shaped plate 17 fixedly installed at its top end. Each L-shaped plate 17 has a fixing rod 18 fixedly installed on its side end. Each fixing rod 18 has a positioning ring 19 fixedly installed at its end. By moving the positioning ring 19, the positioning state of the first connecting plate 15 and the threaded rod 25 is released. At the same time, the end of the L-shaped plate 17 leaves the interior of the first support rod 14, allowing the first connecting plate 15 to slide on its side end. The first connecting plate 15 and the threaded rod 25 can rotate, allowing the angles of the two sets of first clamping plates 11 and second clamping plates 12 to be adjusted. Each first support rod 14 has at least two grooves on its side end.
[0025] Working principle:
[0026] The first step, in use, involves using two first clamps 11 and a second clamp 12 to fix the bone. Simultaneously, the L-shaped plate 17 is pulled, causing it to slide at the side end of the first connecting plate 15. At the same time, the telescopic rod 16 is stretched. The movement of the L-shaped plate 17 causes the fixing rod 18 to move as well. Simultaneously, the fixing rod 18 causes the positioning ring 19 to slide inside the first connecting plate 15 and the second connecting plate 22. The first connecting plate 15 and the second connecting plate 22 rotate relative to each other, and the first connecting plate 15... 5 is rotatably connected to the second connecting plate 22. The rotating shaft inside the second connecting plate 22 and the side end of the first connecting plate 15 are both provided with slots. By moving the positioning ring 19, the positioning state of the first connecting plate 15 and the second connecting plate 22 is released. At the same time, the end of the L-shaped plate 17 leaves the interior of the first support rod 14, allowing the first connecting plate 15 to slide on the side end of the first support rod 14. Meanwhile, the first connecting plate 15 and the second connecting plate 22 can rotate, allowing the angles of the two sets of first clamping plates 11 and second clamping plates 12 to be adjusted, increasing the range of use.
[0027] The second step involves installing ball heads 21 at one end of the first support rod 14 and the L-shaped plate 17. One side of the ball head 21 has a hemispherical design and is connected to the inside of the connecting seat 13 in a ball cage manner, allowing it to deflect and rotate. This facilitates adjustment of the angles of the two first clamping plates 11 and the second clamping plate 12. By rotating the rotating buckle 23, the rotating buckle 23 rotates on the outside of the first clamping plate 11. At the same time, the end of the rotating buckle 23 is rotatably connected to the threaded rod 25. A bevel gear 24 is installed at the top of the threaded rod 25, and the bevel gear 24 is connected to the rotating buckle. The end of 23 is engaged, driving the threaded rod 25 to rotate at the bottom of the first clamp 11. At the same time, the end of the threaded rod 25 rotates at the top of the second clamp 12. By rotating the threaded rod 25, the distance between the first clamp 11 and the second clamp 12 is controlled, and bones of different sizes are clamped and fixed. Meanwhile, buffer pads 26 are installed on the inner sides of the first clamp 11 and the second clamp 12. The buffer pads 26 serve as a separator, reducing the discomfort of the first clamp 11 and the second clamp 12 when fixing the patient's bones.
[0028] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
