Novel passive traction and stretch finger joint rehabilitation apparatus

Abstract

The invention provides novel passive traction and stretch finger joint rehabilitation apparatus. The apparatus comprises a hand back plate assembly, a proximal phalanx assembly, a distal phalanx assembly, a proximal phalanx adjusting assembly, a distal phalanx adjusting assembly and a bandage, the hand back plate assembly comprises a hand back plate, a back plate sliding block and a locking rod, the proximal phalanx assembly is fixed to a proximal phalanx of a finger in a matched mode and comprises a proximal phalanx fixing block, a proximal phalanx fixing sliding block and a locking rod, thedistal phalanx assembly is fixed to a distal phalanx of a finger in a matched mode and comprises a distal phalanx fixing block, a distal phalanx fixing sliding block and a locking rod, the proximal phalanx adjusting assembly comprises a movable jacking block, a movable nut block and a first lead screw, and the distal phalanx adjusting assembly comprises an outer connecting rod, an inner connectingrod and a second lead screw. The invention provides the novel passive traction and stretch finger joint rehabilitation apparatus which is simple in structure, capable of conducting flexion and stretch rehabilitation training on four fingers including index finger, middle finger, ring finger and little finger at the same time, capable of meeting the use requirements of different patients and widein application range.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a novel passive stretching finger joint rehabilitation device. Background technique [0002] The function of the knuckle rehabilitation device is to provide a full range of joint range of motion treatment for the fingers, so that the disabled can recover a certain ability to take care of themselves and work. [0003] At present, finger rehabilitation devices basically adopt exoskeleton structure, and the structure is relatively complicated, which can only be applied to some patients with not very weak muscle strength. Patients cannot perform rehabilitation training step by step during use, have no adjustment function, and cannot control the stretching force, especially those patients who need slight stretching of finger tendons cannot use the knuckle rehabilitation training device currently available on the market. [0004] Finger joints are generally caused ...

AI Technical Summary

Problems solved by technology

[0003] At present, finger rehabilitation devices basically adopt exoskeleton structure, and the structure is relatively complicated, which can only be applied to some patients with not very weak muscle strength

Patients cannot perform gradual rehabilitation training during use, have no adjustment function, and cannot control the stretching force, especially those who need slight stretching of finger tendons, cannot use the knuckle rehabilitation training device currently available on the market

[0004] Finger joints are generally caused by stroke, cerebral hemiplegia, hemiplegia, finger burns, etc., which lead to the inability of the finger joints to flex and extend independently. If the patient is in this state for a long time, it will lead to tendon atrophy, which will have a certain impact on the patient's rehabilitation.

Another one, the passive knuckle rehabilitation devices currently on the market can only perform rehabilitation training for one finger on one hand, and most patients need 2-5 fingers to do rehabilitation training at the same time, which will also put pressure on virtually Slow down the treatment progress, affecting the treatment effect
