Problems solved by technology

Currently existing finger rehabilitation training equipment can already be used for active or passive rehabilitation training of fingers, but because the thumb is the most delicate and dexterous of the five fingers, it has a high degree of freedom, a small range of motion, and is susceptible to damage. Secondary injury, the design requirements for the rehabilitation training sys

Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention is described in detail:

[0024] Such as figure 1 As shown, the three-degree-of-freedom thumb rehabilitation training mechanism of the present invention is composed of a finger movement mechanism, a transmission mechanism and a support seat. Wherein the support seat is composed of a base 20 and a first support plate 15 and a second support plate 19 arranged thereon.

[0025] Transmission mechanism of the present invention such as figure 2 As shown, it consists of a linear motion mechanism and a guide mechanism for generating linear motion, wherein the linear motion mechanism includes a ball screw 7, a ball screw slider 8 and a slider-linear bearing connecting block 9, wherein the ball screw slider 8 are set on the ball screw 7, and the ball screw slider 8 is connected with the slider-linear bearing connection block 9. The guide mechanism includes an optical shaft 10, a linear bearing 11, a roller ...

Abstract

The invention discloses a three-degree-of-freedom thumb rehabilitation training mechanism. The mechanism comprises a support seat as well as a transmission mechanism and a finger movement mechanism which are arranged on the support seat, wherein the finger movement mechanism comprises a joint I, a joint II, a joint III, a joint IV, a front-end finger sleeve and a back-end finger sleeve, the joint II comprises two end hinge points and one middle hinge point, the two end hinge points are connected with the joint I and the joint III respectively, the middle hinge point is connected with the joint IV, the front-end finger sleeve is connected to one end of the joint III, and the back-end finger sleeve is connected to one end of the joint IV; the transmission mechanism comprises a linear motion mechanism and a guide mechanism connected with the linear motion mechanism. The transmission mechanism combines a ball screw, a linear bearing and a rail and converts rotation into arc motion on the rail, so that fingers can swing laterally in space, and finger moves more flexibly and comfortably.

Description

technical field [0001] The invention relates to an active and passive combined three-degree-of-freedom thumb rehabilitation training mechanism. Background technique [0002] The hand is one of the most distinctive organs on the human body. Scientists believe that the hand is one of the three important organs that enable people to have a high degree of intelligence. It is an important tool for human beings to understand and transform the world. It is the most dependent part of people's daily life and one of the most vulnerable parts. Among the five fingers of a person, the thumb is particularly important. It can move in coordination with the other four fingers to complete actions such as holding and pinching. It is very common for various neuromuscular disorders such as stroke to cause loss of hand hemiplegia, and hand flexion and extension is the most frequently damaged motor function, which seriously affects the patient's personal self-care ability and brings social and fa...
