Hand prosthesis with microprocessor control

Prosthetic hand with microprocessor control. The prosthesis is designed for partial compensation of congenital or acquired injuries resulting in amputation of upper limbs at the finger/wrist level.
The prosthesis consists of two main parts: hand and forearm. The hand consists of an internal sleeve in which electrodes are optionally installed, finger modules consisting of a gearmotor and kinematic mechanism housed in the finger housing. The forearm consists of an optional inner sleeve made in two variations: with electrodes on the forearm or in the hand, a power system including a battery and power management board, a charging and switching module, a control system, and an outer sleeve. The prosthesis is retained on the residual limb by anatomical features of the residual limb and/or by a tie strap. The prosthesis is controlled by recording an electromyographic signal on the skin surface of the forearm or hand by means of myo-sensors located in the inner sleeve.
