Abstract

The invention belongs to the technical field of rehabilitation medical apparatuses and instruments, and provides an artificial hand. The artificial hand comprises a supporting structure, a thumb structure, a finger structure and at least one first drive structure; each first drive structure comprises a first drive component, a first transmission assembly, a lead screw, a lead screw sliding block,a guiding rod and a first wiring base which are arranged on the supporting structure; the head end of the first transmission assembly is connected with the output end of the first drive component, thetail end of the first transmission assembly is connected with the lead screw and used for transmitting power of the first drive component to the lead screw; the lead screw sliding block sleeves the lead screw and the guiding rod so that rotation of the lead screw can be converted into linear motion of the lead screw sliding block in the axial direction of the lead screw; linear motion of the leadscrew sliding block drives a thumb tendon rope and a finger tendon rope to be stretched or released so that the index finger, the middle finger, the ring finger, the little finger and the thumb finger can perform coupling flexion and extension motions. The finger structure and the first drive structure adopt the modularized design, individual design is performed, and the structure of the artificial hand of various degrees of freedom can be achieved.

Description

technical field [0001] The invention relates to the technical field of rehabilitation medical equipment, in particular to a prosthetic hand. Background technique [0002] The humanoid prosthetic hand provides convenience for the daily life of disabled persons with missing upper limbs, and is an important research direction in the field of rehabilitation engineering. Currently commercialized prosthetic hands are The company's safe proportional control myoelectric hand, the high-precision myoelectric control prosthesis iLimb produced by the British Scottish company (Touch bionics), etc. Among them, the safe proportional control myoelectric hand has three fingers (thumb, index finger and middle finger), which can complete the opening and closing of the hand to realize the grasping function, but its fingers are integral and cannot realize multi-knuckle coupling movement; iLimb has five The prosthetic hand with only one finger can independently control the movement of each fin...
