3Dprinting myoelectricity bionic artificial limb arm

Abstract

A 3Dprinting myoelectricity bionic artificial limb arm belongs to the technical field of medical apparatuses. The artificial limb arm comprises an upper arm, a forearm, an elbow joint and a palm; the upper arm is connected with the forearm through the elbow joint; the elbow joint is provided with a rotary motor and a bending motor therein; a top end of the elbow joint is buckled with a bottom of the upper arm; the forearm comprises an upper segment arm, a middle segment arm and a lower segment arm which are communicated; a top end of the upper segment arm is movably connected with a bottom end of the elbow joint; a bottom end of the lower segment arm is movably connected with the palm; a circuit board is built in the upper segment arm; a control motor is built in the middle segment arm; a branching hole is built in the lower segment arm; the control motor, the bending motor and the rotary motor are connected to the circuit board; the palm comprises five fingers, a pull wire fixing part which is used for fixing pull wires is built in a finger tip of each finger; the pull wire in each finger passes through two branching holes and surrounds between the corresponding pull wire fixing part and control motor. The bionic artificial limb arm of the invention is obtained through 3D printing so that the outlook of the bionic artificial limb is matched with patients and the wearing fitness is high.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a 3D printed myoelectric bionic prosthetic arm. Background technique [0002] Physical disabilities will cause great troubles to people's lives. At present, the demand for prosthetic limbs in my life is extensive, but what is embarrassing is that the number and variety of prosthetic limb products in my country are scarce, the performance is single, and they lack timely innovation. There is a large gap between. my country's prosthetic product market is mainly occupied by foreign companies, but imported products are often expensive, and 75% of my country's handicapped people are distributed in vast cities and rural areas. Because most of the amputees are poor people, the penetration rate of artificial limbs is not high. It is estimated that about 70% of the people have not installed artificial limbs; and the upper limb artificial limbs currently on the market mainly include...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a 3D printed myoelectric bionic prosthetic arm to solve the problems that the existing myoelectric simulation arm is difficult to control the grip force, the grasping method is not bionic enough, and cannot rotate.
