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 invention provides a finger auxiliary rehabilitation finger cot based on a pneumatic soft-bodied actuator and a manufacturing method of the finger auxiliary rehabilitation finger cot. The auxiliary rehabilitation finger cot comprises one or more spiral actuators and a connecting ring stuck to the corresponding spiral actuator according to the position of a finger joint of a patient. The initial configuration of the rehabilitation finger cot is spiral, the rehabilitation finger cot can naturally produce bending deflection without inflation to be adapted to the finger joint of the patient so as to bend into a spiral shape; and according to the shape, configuration space parameters of the spiral actuator are selected, so that the finger cot can effectively help the patient to unfold rigid bent fingers in a manner that the patient can feel comfortable. Through experiment confirmation by a prototype machine, under different input air pressure, the prototype machine can be unfolded to different angles, and the bent finger can be unfolded to different shapes. Because the input air pressure is distributed in the entire length of an executing mechanism, the finger cot can be used for all of parts of the finger.

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...
