Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0039] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a multi-joint bionic dexterous tendon-driven artificial hand includes a wrist 11 and a palm cavity 12 connected to the wrist 11. A plurality of multi-joint bionic fingers 2 are installed on the palm cavity 12. Inside the palm cavity 12 The passive part 3 is provided, and the palm cavity 12 is provided with an active part 4 that can be installed on the arm and can use the relative rotation of the arm joints as power to drive the passive part 3 to gradually advance; the multi-joint bionic finger 2 is provided with a tendon transmission part 5 and a plurality of elastic connectors 6 respectively located at each joint of the multi-joint bionic ...

Abstract

The invention discloses a multi-joint bionic dexterous tendon-transmission artificial hand which comprises a palm cavity. A plurality of multi-joint bionic fingers are mounted on the palm cavity, a passive portion is arranged in the palm cavity, and an active portion which can be mounted on an arm and can drive the passive part to gradually push by taking the relative rotation of the arm joint aspower is arranged outside the palm cavity; the active portion is linked with the passive portion and drives the multi-joint bionic fingers through a tendon transmission portion, so that all multi-joint bionic fingers on the artificial hand are gradually closed or opened along with the gradual push of the passive portion. According to the artificial hand, all the multi-joint bionic fingers on the artificial hand are gradually closed along with the gradual push of the passive portion so that the gripping strength and the gripping degree of the multi-joint bionic fingers can be freely controlledaccording to the bending degree of the arm when an object is taken, electric power is not needed, the multi-joint bionic dexterous tendon-transmission artificial hand is simple in structure and convenient to use, has a practical gripping function, and accordingly meets the higher requirement of a user for the passive artificial hand.

Description

technical field [0001] The invention relates to a mechanical bionic hand, in particular to a multi-joint bionic dexterous tendon-driven artificial hand. Background technique [0002] Various natural disasters and accidents have resulted in an increasing number of amputees. Given the various pressures they are facing in life, many amputees hope to choose to wear artificial limbs to complete some corresponding actions and improve their employability. [0003] The prosthetic hand is an important tool to assist hand disabled patients to complete the grasping of objects. The traditional claw-shaped prosthetic hand has only one degree of freedom for the fingers, and cannot use irregular shapes of objects. When grasping objects, the contact surface between the fingers and the object is small , which is not conducive to the stable grasping of objects. At the same time, due to the small contact area between fingers and objects, the clamping force of the claws is mainly concentrated o...
