Description

Technical Field

[0001] This invention relates to the field of orthopedic rehabilitation technology, specifically to a multi-angle traction and fixation device for the leg used in medical surgery. Background Technology

[0002] In orthopedic surgery and postoperative rehabilitation, multi-angle traction and fixation of the leg are common treatment methods, playing an important role in maintaining fracture alignment, relieving muscle spasms, and preventing joint stiffness. Existing medical leg traction and fixation devices are generally structurally simple and mainly suffer from the following technical problems: First, existing traction devices mostly use a fixed frame and a single-direction suspended weight, meaning the traction force can only be applied vertically or along a single axis. This makes it difficult to meet the clinical need for multi-angle, variable-direction traction for different leg positions (such as flexed, extended, and abducted). When the traction angle needs to be adjusted, it is often necessary to move the entire device or re-tie the fixation straps, which is cumbersome and can easily cause patient discomfort.

[0003] Secondly, existing devices have low functional integration, typically only offering single functions such as passive traction or static fixation, and cannot switch between active rehabilitation training and passive traction on the same device. If patients need joint range of motion training or muscle strength recovery during treatment, they must leave the traction device and transfer to other rehabilitation equipment, increasing the risks of transport and the workload of medical staff.

[0004] Furthermore, the leg support and fixation components of existing devices are mostly one-piece or fixed designs, lacking modular replacement structures. Different leg support and restraint are required for different conditions (such as post-hip surgery, post-knee replacement surgery, simple lower leg fractures, etc.), and existing equipment is difficult to adapt flexibly, resulting in limited clinical applicability. Hospitals need to configure a variety of different specifications of traction devices, which takes up space and is costly. Summary of the Invention

[0005] This invention proposes a multi-angle traction and fixation device for the legs in medical surgery, which solves the problems of improper height and single function in related technologies.

[0006] The technical solution of the present invention is as follows: a multi-angle traction and fixation device for legs in medical surgery, comprising a traction assembly, the traction assembly including a traction frame and a gravity block disposed within the traction frame; a seat assembly disposed below the traction frame, the seat assembly including a seat frame and a seat body disposed on the seat frame; and a training assembly detachably mounted on the seat assembly, the training assembly being connected to the traction assembly for traction and / or fixation of the user's legs.

[0007] As a preferred embodiment of the present invention, the traction assembly further includes a guide rod, a connecting guide wheel, a top guide wheel, and a bottom guide wheel disposed within the traction frame. The gravity block is slidably disposed on the guide rod, and the connecting guide wheel, the top guide wheel, and the bottom guide wheel cooperate with the rope to change the direction of the traction force.

[0008] As a preferred embodiment of the present invention, the seat assembly further includes a backrest and a backrest adjustment slider, wherein the backrest is mounted on the seat frame at an adjustable angle via the backrest adjustment slider.

[0009] As a preferred embodiment of the present invention, the training component is a first replacement training component, which includes a connecting frame, a waist fixation device disposed on the connecting frame, and a double-sided fixing block, a thigh support block, a calf support block and a foot support block arranged in sequence.

[0010] As a preferred embodiment of the present invention, the first replacement training component further includes a thigh connection collar and a joint rehabilitation aid, wherein the joint rehabilitation aid includes an auxiliary motor, a first reduction gear, a second reduction gear and a third reduction gear, for providing auxiliary rehabilitation power to the user's joints.

[0011] As a preferred embodiment of the present invention, the training component is a second alternative training component, which includes a hinge block, a lifting rod connected to the hinge block, and a leg lifting block disposed on the lifting rod.

[0012] As a preferred embodiment of the present invention, the lifting rod is provided with a rope connection point for connecting to the pulling assembly via a rope.

[0013] As a preferred embodiment of the present invention, the training component and the seat component are detachably connected by plugging or snapping.

[0014] The working principle and beneficial effects of this invention are as follows: 1. This invention, through the design of backrest adjustment sliders, gravity blocks, and other structures, allows patients to flexibly adjust the backrest angle to meet different body posture needs. At the same time, the gravity block slides vertically on the guide rod and transmits traction force through multi-stage reversal of the connecting guide wheel, top guide wheel, and bottom guide wheel. This enables multi-angle traction without frequently moving the patient's body, effectively reducing stiffness and local pressure discomfort of the affected limb during prolonged fixation, and significantly improving the overall comfort of the treatment position.

[0015] 2. This invention achieves efficient integration of passive fixation and active rehabilitation functions on the same platform through the design of the first replacement training component and the joint rehabilitation aid. The first and second replacement training components are modularly detachable and can be connected by plug-in or snap-fit, allowing for quick replacement of the corresponding support structure according to different disease stages. At the same time, the joint rehabilitation aid, through the coordinated transmission of the auxiliary motor and multi-stage reduction gears, provides patients with stable and controllable assisted movement power, ensuring the safety of early postoperative passive activities while covering the needs of later active strength training, thus significantly expanding the clinical applicability of the device.

[0024] The first replacement training component 3 also includes a thigh connection collar 37 and a joint rehabilitation aid 38. The joint rehabilitation aid 38 includes an auxiliary motor 381, a first reduction gear 382, ​​a second reduction gear 383 and a third reduction gear 384, which are used to provide auxiliary rehabilitation power to the user's joints.

[0025] The training component is a second alternative training component 4, which includes a hinge block 41, a lifting rod 42 connected to the hinge block 41, and a leg lifting block 43 disposed on the lifting rod 42.

[0026] The lifting rod 42 is provided with a rope connection point 44 for connecting to the pulling assembly 1 via a rope.

[0027] The training component and the seat component 2 are detachable connected by a plug-in or snap-fit ​​mechanism.

[0028] Working principle: Before use, select the first replacement training component 3 or the second replacement training component 4 according to rehabilitation or surgical needs, and detachably install them on the seat frame 21 by plugging or snapping. The patient sits on the seat body 22 and adjusts the backrest 23 angle to a comfortable position using the backrest adjustment slider 24.
