Prosthetics is a recovery of the got out of shape and functions of separate bodies or parts of a body.
Prosthetic engineering is engaged in development and production of artificial technical means of recovery.
The disabled people who transferred such amputation lose first of all an opportunity to self-service, and in most cases also lose a profession.
Therefore purpose of prosthetics of upper extremities: return of the disabled person to a possibility of self-service and to work. As artificially it is difficult to reproduce all functionality of a healthy human hand at the present stage of technical development, the main objective of prosthetic engineering is a creation of an engineering device capable as much as possible to fill the lost functions, that is to return to the disabled person an opportunity to make the main household movements. Such movements are: gripper and manipulation of a subject.
