Problems solved by technology

This method requires more parts and is complicated to install, which increases the overall weight of the prosthesis
Whether it is the motor, transmission parts, electronic components inside the prosthesis, or the external metal structural parts, waterproof and dustproof measures are required, and this method is only for the motor, and it is difficult to ensure the normal use of the powered prosthesis

Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the existing powered below-the-knee prosthesis generally includes a calf prosthesis 1, an opening 2 for charging or other purposes is arranged on the calf prosthesis 1, and a foot prosthesis 4 is connected to the lower end of the calf prosthesis 1 through an ankle 3.

[0016] Such as figure 2 As shown, the device of the present invention includes a calf covering layer 5 that fits with the calf prosthesis 1, and a through hole is opened on the calf covering layer 5 relative to the opening 2; corresponding to the through hole, a size that can be opened is slightly larger than the through hole A cap-like cladding 6 for the hole. A plug 7 is arranged on the cover-shaped cladding layer 6, and the plug 7 and the opening 2 of the calf prosthesis 1 can be sealed by interference fit, so as to play the role of waterproof and...

Abstract

A waterproof and dustproof device for a powered below-knee prosthesis and a production method thereof. The waterproof and dustproof device comprises a shank coating layer attached with a prosthesis shank, a foot coating layer attached with a prosthesis foot, and an ankle coating layer. The ankle coating layer is matched with an ankle in shape and sleeved outside the shank coating layer and the foot coating layer. The ankle coating layer is fixedly connected with the lower portion of the shank coating layer and the upper portion of the foot coating layer respectively. A through hole is arranged on the shank coating layer. An openable cover-shaped coating layer is disposed on the shank coating layer corresponding to the through hole. A plug which can penetrate through the through hole and be plugged into an opening of the prosthesis shank is disposed on the cover-shaped coating layer. The waterproof and dustproof device is widely applicable to water proofing and dust proofing for various prosthesises.

Description

technical field [0001] The invention relates to a waterproof and dustproof device and a manufacturing method thereof, in particular to a waterproof and dustproof device for a powered under-knee prosthesis and a manufacturing method thereof. Background technique [0002] According to whether the prosthesis provides energy during human walking, prosthetics can be divided into passive prostheses and powered prostheses. The powered under-knee prosthesis provides the energy needed by people during walking through active work, and can automatically adjust the angle of the ankle joint. The realization of the above functions depends on the motor, power supply and control circuit. When the motor and control circuit encounter water or dust, on the one hand, it will reduce its working efficiency or even fail to work normally. On the other hand, it will cause more energy loss and reduce the energy efficiency of the wearer when walking. At present, there is a waterproof and dustproof me...
