Research On Exoskeleton System For Rehabilitation Of Injured Finger

In today’s society, people pay more and more attention to their health.this makes the rehabilitation medical technology develop rapidly. Rehabilitation is also becoming more and more diversified, more and more advanced.At the same time,the research field of robot is in constant expansion.People pay more and more attention to rehabilitation robot research.Especially in the rehabilitation of patients with physical disabilities,patients can get faster and better rehabilitation training.The rehabilitation exoskeleton that this paper studied is for the rehabilitation of stroke patients trained medical devices in the fingers.Firstly,in this paper, we study the current situation at home and abroad about the finger rehabilitation exoskeleton summary and analysis system.On the basis of this analysis,we summarize the advantages and disadvantages of the existing fingers appear rehabilitation exoskeleton design.The new design of finger rehabilitation programs exoskeleton is then raised.Under the premise of rehabilitation can be achieved,We avoid shortcomings and deficiencies of other exoskeleton designs.Secondly,before we carry out the structural design of the exoskeleton,we want to process normal finger size and finger bending motion of the experimental study.By drawing the basic dimensions of normal finger,we concluded outside the base as the size of the finger bones.Through the study of finger bending process,The relationship between the rotational speed of each finger joint will be get.Conclusion can be used for the design applied to the control part of the exoskeleton.Thirdly,by the foundation that we get about finger size and bending motion before,we propose the principle of movement rehabilitation exoskeleton finger.After we do in-depth research on the principle of movement we selected,we design the exoskeleton structure including all components.At the same time, we take the use of three-dimensional mapping software to model a finger exoskeleton.Then we do the kinematics and dynamics analysis of the finger exoskeleton we designed.Finally,we do the final design of the finger exoskeleton of driving and control parts.Thus,we can obtain relatively complete rehabilitation finger exoskeleton design.Through simulation software,we validate the finger exoskeleton we have designed and we can get the corresponding conclusions.Through simulation software we try to simulate the bending motion of the external skeletal to verify the reasonableness of the motor we selected.By the stress and strain analysis of the part which bear a larger force,we can verify that the structure of the material selected is reasonable or not.
