Hand knuckle rehabilitation training mechanism

Abstract

The invention discloses a hand knuckle rehabilitation training mechanism and relates to the technical field of rehabilitation devices. The hand knuckle rehabilitation training mechanism comprises a hand training mechanism and a transmission mechanism, wherein the hand training mechanism comprises a four-finger training mechanism and a thumb knuckle plate. According to different physiological structures of five fingers of the hand, the four-finger training mechanism and the thumb knuckle plate are adopted for independent training, motion interference in a narrow space is avoided, holding actions of four fingers and local rotation of the thumb are achieved, the lengths of knuckle plates can be adjusted, and personalized training is achieved. A parallel six-rod mechanism is adopted in the four-finger training mechanism, fast first and last slow rehabilitation training stable in drive is achieved, and the actual holding rule of the hands is greatly recovered. Quick and convenient dismounting of a drive rod and adjustment of a drive rod installing position are achieved through exercise and limiting of a secondary slide block, thus the exercise angles of knuckles are adjusted in a certain range, meanwhile the length of the driven rod is adjustable, the exercise angles of the knuckles can be further adjusted, and the purpose of meeting different rehabilitation training demands is achieved.

Description

technical field [0001] The invention relates to the technical field of rehabilitation equipment, in particular to a rehabilitation training mechanism for hands. Background technique [0002] The finger joints are the connection points between the bones of the human finger bones, the joints between the bones and the cartilage, and are also the links that play a key role in hand movements. Due to the special position and structure of the finger joints, they are prone to damage during daily exercises and sports. For the elderly, the finger joints not only have sports injuries, but also tend to suffer from decreased joint mobility and coordination as they age. In addition, the incidence of stroke in my country has increased year by year in recent years, and a large number of stroke patients have symptoms of hemiplegia, which in turn leads to hand dysfunction. At present, the structure of the training institutions of hand rehabilitation equipment in hospitals and community reha...

AI Technical Summary

Problems solved by technology

At present, the structure of the training institutions of hand rehabilitation equipment in hospitals and community rehabilitation departments is not simple enough, which is very easy to cause movement interference during exercise, which affects the normal progress of rehabilitation training

At the same time, its training mode is not ideal for restoring the law of human grasping, and it is difficult to stimulate the potential recovery ability of patients
