Problems solved by technology

[0002] The initial configuration of the rehabilitation finger cuffs designed in the prior art is mostly a straight line, which is bent and deformed by inflation to drive the finger joints to bend, but the initial configuration of the fingers of most patients is not a straight line, but various irregular shapes
If the rehabilitation cuff cannot be designed according to the original shape of the patient's finger, the patient will feel pain and discomfort wearing the cuff

Embodiment Construction

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for both fixing and circuit communication.

[0031] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", ...

Abstract

The present invention provides a pneumatic software actuator-based auxiliary finger rehabilitation finger cot and its manufacturing method. The auxiliary rehabilitation finger cot includes at least one helical actuator, and is pasted on the Connecting ring on a solenoid actuator. The initial configuration of the rehabilitation finger cuff is helicoidal, and it can naturally produce bending deformation without inflating it to adapt to the patient's finger joints. , can more effectively and comfortably help patients to stretch their stiff and crooked fingers. Prototype experiments have confirmed that under different input air pressures, the prototype can be unfolded at different angles, and the curved fingers can be unfolded into different shapes. Since the input air pressure is distributed over the entire length of the actuator, all parts of the finger can be exercised.

Description

technical field [0001] The invention relates to the technical field of soft robots, in particular to the design of a finger-assisted rehabilitation finger cot based on a helical pneumatic soft actuator and a manufacturing method thereof. Background technique [0002] The initial configuration of rehabilitation finger cuffs designed in the prior art is mostly a straight line, which is bent and deformed by inflation to drive the finger joints to bend. However, the initial configuration of the fingers of most patients is not a straight line, but various irregular shapes. If the rehabilitation finger cot cannot be designed according to the original shape of the patient's finger, the patient will feel pain and discomfort wearing the finger cot. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a finger-assisted rehabilitation finger cot based on a pneumatic soft actuator and a manufacturing method ther...
