Description

Technical Field

[0001] The invention relates to the technical field of medical appliances, in particular to a support device for trauma orthopedics. Background Art

[0002] During traumatic orthopedic surgery and postoperative rehabilitation, the patient's legs need to maintain a specific posture to ensure the treatment effect and promote recovery. However, existing orthopedic support devices have the following problems during use:

[0003] Single fixation method: Traditional support devices mostly use simple straps or pads for support, which are difficult to flexibly adjust according to the different needs of patients, resulting in the difficulty in controlling the leg support angle and strength, affecting the rehabilitation effect.

[0004] Inconvenient adjustment: The existing support devices are relatively simple to adjust, usually only providing limited angle adjustment, which cannot meet the needs of different surgeries and the rehabilitation requirements of individual patients. Some devices require manual adjustment by medical staff, increasing the burden of care.

[0058] Here’s how it works:

[0059] 1. Overview of the device structure

[0060] The support device is mainly composed of a bed board, an adjustment mechanism 2 and a foot 1. The bed board is divided into multiple parts: a head board 4, a back board 5, a waist board 6, a bottom board 3 and a leg board 10. The bottom board 3 is installed on the upper part of the adjustment mechanism 2, and the other parts (head board 4, back board 5, waist board 6, leg board 10) are installed on the bottom board 3. The waist board 6 and the leg board 10 are arranged at intervals to facilitate adjustment and support.

[0061] 2. Core components and their functions

[0062] Bottom support assembly 8: connects the bottom plate 3 and the leg plate 10, so that the leg plate 10 can rotate around the bottom plate 3, which is convenient for adjusting the position of the leg plate 10 in the horizontal plane.

[0063] Foot support assembly 7: installed at the upper end of the leg plate 10, used to fix the user's feet and ensure that the feet are in the target position.

[0064] The leg support assembly 9 is installed on the upper end of the waist plate 6 near the leg plate 10, and is used to support the thigh of the user after the user's feet are fixed to disperse the gravity.

[0065] 3. Working Principle

[0066] Height adjustment: Medical staff can adjust the height of the bed board through the adjustment mechanism 2 to meet the needs of different patients.

[0067] Leg board 10 position adjustment: The position of the leg board 10 in the horizontal plane is adjusted by the bottom support assembly 8. The bottom support assembly 8 includes a support frame 83 and a locking unit, and the locking unit realizes the fixing and rotation of the leg board 10 through the meshing of the gear 84 and the inner gear ring 88.

[0068] When the pull rod 81 is pulled, the locking spring 85 is compressed, the gear 84 is separated from the inner gear ring 88, and the leg plate 10 can rotate freely.

[0069] After the pull rod 81 is released, the locking spring 85 pushes the gear 84 to engage with the inner gear ring 88, and the leg plate 10 is fixed.

[0070] Foot fixation: The user's foot and calf are placed on the foot support assembly 7 and fixed by a medical bandage. The foot support assembly 7 includes a base 76, a rotating shaft 77, a crossbeam 78, a first guide rod 73 and a foot placement seat 71. By adjusting the position of the foot placement seat 71, the user's legs can be bent and opened.

[0071] Thigh support: The leg support assembly 9 is used to support the user's thigh and disperse the gravity. The leg support assembly 9 includes a slide plate 94, a second guide rod 95, a second positioner 93 and a leg placement seat 91. By sliding the second positioner 93, the leg placement seat 91 can support the lower part of the user's thigh and distribute the gravity on the leg after being fixed.

[0072] 4. Specific regulatory mechanisms

[0073] Bottom support assembly 8: The leg plate 10 is rotated and fixed by the cooperation of the pull rod 81 and the locking spring 85. When the pull rod 81 is pulled down, the leg plate 10 can rotate around the axis; after the pull rod 81 is released, the leg plate 10 is locked in the current position.

[0074] Foot support assembly 7: The position of the foot support seat 71 is adjusted through the screw rod 724 and the pressure block 722 of the first positioner 72. When the screw rod 724 is tightened, the pressure block 722 and the first guide rod 73 are in friction contact to fix the foot support seat 71; when the screw rod 724 is loosened, the foot support seat 71 can slide or rotate.

[0075] Leg support assembly 9: By adjusting the cooperation between the cylinder 932 and the jacket 933, the second guide rod 95 is clamped or loosened, thereby fixing or adjusting the position of the leg placement seat 91.

[0076] The trauma orthopedic support device achieves precise control of the height, angle and support force of the patient's legs through the coordinated work of multiple adjustable components.
