ELECTRIC DRIVE MECHANISM OF FINGER OF BIONIC BRUSH Russian patent published in 2023 - IPC A61F2/54 

FIELD: medical equipment.

SUBSTANCE: invention relates to drive mechanisms for the fingers of bionic multi-grip hands. The electric drive mechanism of the bionic hand finger contains a gearbox housing, a motor, a motor gearbox installed in the gearbox housing, a worm installed inside the gearbox housing on the motor gearbox shaft, a worm ring made to engage with the worm and fixed to the axis of the gearbox housing, lower and upper rods, as well as a finger in which the first and second axes of the finger are made. The upper link is pivotally connected at one end to the axis of the gearbox housing, and at the other end it is pivotally connected to the first axis of the pin. The lower link is pivotally connected at one end to the axis of the gearbox housing, and at the other end it is pivotally connected to the second axis of the pin. A compression spring is installed inside the pin. The upper rod and the lower rod are designed to form a lever for bending the finger.

EFFECT: increasing the reliability of the mechanism, preventing the possibility of breakdowns as a result of a collision of a finger with an obstacle, and increasing the durability.
