Walking aid capable of replacing shank load bearing

Abstract

A walking aid capable of replacing shank load is designed to embrace and fix the thigh of an affected limb, be connected with a movable chuck and be connected with a walking aid body, plays a role in replacing shank load, and is used for assisting walking of patients with tibia trunks and fractures below the tibia trunks and used for assisting walking in the rehabilitation period when the fractures are not healed.

Description

Technical Field

[0001] Medical auxiliary equipment. Background Art

[0002] During the period from internal fixation of orthopedic trauma fractures to fracture healing, the affected limb is prohibited from bearing weight, restricting the patient's out-of-bed activities and losing self-care ability. Therefore, a walking aid that replaces the weight-bearing of the calf is designed. By surrounding and fixing the thigh of the affected limb, connecting a movable chuck, and connecting the main body of the walking aid, the thigh and knee jointly serve as the supporting force points, playing the role of replacing the weight-bearing of the calf. It is used for patients with fractures in the tibial shaft and below, assisting walking during the rehabilitation period when the fracture has not healed, increasing the patient's self-care ability, helping to reduce bedridden complications, muscle atrophy, and the risk of lower limb venous thrombosis. Summary of the Invention

[0003] A walking aid that replaces the weight-bearing of the calf is composed of two ends at the upper part of the "Y"-shaped walking aid main body (1) connected to two limit chucks (2), and then connected to the thigh surrounding and fixing device (5) and the knee fixing device (6). The lower end of the "Y"-shaped walking aid main body (1) is installed with rubber feet (9) in contact with the ground. Brief Description of the Drawings

Detailed Description of the Invention

[0005] A walking aid that replaces the weight-bearing of the calf is composed of two ends at the upper part of the "Y"-shaped walking aid main body (1) connected to two limit chucks (2), and then connected to the thigh surrounding and fixing device (5) and the knee fixing device (6). The lower end of the "Y"-shaped walking aid main body (1) is installed with rubber feet (9) in contact with the ground.

[0006] The connection method between the two ends at the upper part of the Y-shaped walking aid main body (1) and the two limitable chucks (2) is as follows: the rotating shaft (3) in the central bearing (4) of the limitable chuck (2) is clamped into the "U" groove (17) at the upper end of the Y-shaped walking aid main body (1), the placeholder (13) is installed, and the fixing bolt (10) is inserted for connection. During installation, it needs to be tilted backward by 45° and the fixing column (8) is inserted along the opening (14) of the limitable chuck (2) so that the fixing column (8) can slide limitedly in the sliding groove (16) of the limitable chuck (2). Fixing holes (15) are designed on the sliding groove (16) to facilitate the installation of bolts to adjust the sliding range of the fixing column (8), thereby changing the limiting angle.

[0007] Nested telescopic devices (11) are installed at both the upper and lower ends of the Y-shaped walking aid main body (1) to adapt to different body sizes and limb lengths.

[0008] A handle (7) is designed on the Y-shaped walking aid main body (1).

[0009] A leg rest (12) conforming to the shape of the calf is designed behind the fork of the Y-shaped walking aid main body (1).

[0010] Mirror symmetry design is made according to the left and right limbs.

[0011] The design material is steel, aluminum alloy or other materials with suitable strength.

Claims

1. A walker that replaces calf weight bearing, characterized in that a Y-shaped walker body (1) is designed, and a limitable chuck (2), a thigh encircling fixing device (5) and a knee fixing device (6) are connected to form a walker structure in which the thigh bears gravity.

2. The design of connecting the Y-shaped walking aid body (1) and the limitable chuck (2) is characterized in that the rotating shaft (3) in the central bearing (4) of the limitable chuck (2) is inserted into the "U"-shaped groove (17) at the upper end of the Y-shaped walking aid body (1), the placeholder (13) is installed, and the fixing bolt (10) is inserted to connect.

3. The Y-shaped walker body (1) is connected to the limitable chuck (2) and then the limitable movable design is adopted. The feature of the design is that the opening (14) of the limitable chuck (2) is embedded in the fixed column (8), so that the fixed column (8) can slide limitedly in the sliding groove (16) of the limitable chuck (2). The sliding groove (16) is provided with a fixing hole (15) for conveniently installing a bolt therein to adjust the sliding range of the fixed column (8), thereby changing the limit angle.

4. The Y-shaped walker body (1) is designed with some accessories, and the upper and lower ends are installed. The feature is that the Y-shaped walker body (1) has a telescopic and retractable device (11), so that it can adapt to different body shapes and limb lengths. The Y-shaped walker body (1) is designed with a handle (7). The Y-shaped walker body (1) is designed with a leg support (12) that fits the shape of the calf behind the bifurcation.

5. Make mirror image design based on the left and right limbs.

6. The design of the present invention is not limited to materials.
