Adaptive bionic mechanical prosthesis and the control method thereof

Abstract

The purpose of this invention is to provide an adaptable bionic mechanical prosthesis and its operation mode. To meet the wearing convenience of different users, the prosthesis of this invention has a drive element installed in the palm position so that the shape or structure of the prosthesis can be adjusted according to the user's needs. It also has a switch that the user can switch to maintain the current action or perform grasping or gripping actions.

Claims

1. An adaptable bionic mechanical prosthesis, comprising: an arm portion including a wearing opening and a control unit, wherein the wearing opening is disposed at one end of the arm portion, and the control unit is disposed in the arm portion; a palm portion connected to the arm portion and a wrist portion, wherein the wrist portion is disposed at the end of the arm portion away from the wearing opening, wherein... The palm portion also includes at least one transmission member connected to the control unit; and a finger portion connected to the transmission member, comprising a first finger portion and a second finger portion, wherein the second finger portion is disposed at one end of the palm portion away from the wrist portion, wherein the first finger portion is disposed on one side of the palm portion and located between the second finger portion and the wrist portion, and is not coplanar with the second finger portion; wherein, after the control unit acquires a muscle signal, it outputs a control signal to the palm portion and controls the finger portion to move.

2. The adaptable bionic mechanical prosthesis as claimed in claim 1, wherein the control unit further includes a detection electrode disposed on the arm, wherein the detection electrode includes a flexible resistor or an electrode patch.

3. The adaptable bionic mechanical prosthesis as described in claim 1, further comprising a switch element disposed on the wrist and signal-connected to the transmission elements, wherein, This switch can selectively stop the operation of the transmission component.

4. The adaptable bionic mechanical prosthesis as described in claim 1, wherein there are multiple transmission components, and each component transmits and controls the first finger and the second finger respectively.

5. The adaptable bionic mechanical prosthesis as claimed in claim 1, wherein the angle between the first finger and the second finger is between 60˚ and 90˚.

6. The adaptable bionic mechanical prosthesis as described in claim 1, wherein the first finger portion includes a first finger component, and the second finger portion includes a second finger component, a third finger component, a fourth finger component, and a fifth finger component, wherein, The first finger, the second finger, the third finger, the fourth finger, and the fifth finger are each connected to at least one of the transmission components; or the palm is flat, and the transmission components connecting the second finger, the third finger, the fourth finger, and the fifth finger are arranged linearly or in an arc shape with equal spacing; or the palm is arched, and the connection surfaces of the transmission components connecting the second finger, the third finger, the fourth finger, and the fifth finger with the second finger, the third finger, the fourth finger, and the fifth finger are on the same plane or a non-coplanar curved surface.

7. The adaptable bionic mechanical prosthesis as claimed in claim 1, wherein the finger portion comprises a conductive elastomer on the side away from the palm portion.

8. A control method for an adaptable bionic mechanical prosthesis, comprising the following steps: Step 1: a control unit acquires a muscle signal; Step 2: the control unit transmits a control signal to one or more transmission components; and Step 3: after receiving the control signal, the transmission component controls at least a first finger or a second finger to close to grasp an object.

9. The control method as described in claim 8, wherein the control unit further includes a detection electrode for detecting the muscle signal, wherein the detection electrode includes a flexible resistor or an electrode patch.

10. The control method as described in claim 9, wherein the muscle signal comprises a first muscle signal and a second muscle signal; wherein, When the detection electrode outputs the first muscle signal, the control unit transmits a first control signal and controls the first finger to close; when the detection electrode outputs the second muscle signal, the control unit transmits a second control signal and controls the second finger to close.
