This is a prosthesis that allows the wrist-cutting disabled person wearing the elbow of the prosthesis associated with the Utility Model Registration No. 351275 registered by the present applicant to be used more safely and conveniently. It is also possible to live.

In general, the injured fingertips, which are the most needed for the handicapped person's forefinger who has a cuff cut, are inclined in a straight line so that they can be brought into close contact with each other.

The prostheses according to the prior art could not pick up a small object on the floor because each fingertip is rounded and made of a hard material.

The present invention was devised to solve the above problems, the arm or the wrist is pulled by the hand to the arm of the dismembered hand to the throttle control panel moves the wire control member and switch control member to the motor control panel connected to the wire control member and switch By pulling the wire connected to the thumb and forefinger, it is possible to use it as an alternative option.

In order to achieve the above object, the present invention has the upper arm guard and the lower arm guard is hinged, the thumb frame and index finger of the prosthesis are coupled with the hinge so that the fingers are deployed or pinched, the elbows are bent. Move towards your side to pull the wires connected to the wire control member and the motor or throttle to allow the fingers to unfold or pinch.

In addition, the index finger and the index finger and the end of the glove is formed to be inclined in a straight line to be in close contact with each other.

Hereinafter, the prosthesis for the disabled of the present invention will be described with reference to the accompanying drawings.

1 is a perspective view of a preferred use state of the present invention, the disabled person with the cuff cut off wearing a prosthesis and using the movement of the throttle plate 10 to obtain the function of the finger.

Figure 2 is a perspective view of the shape of the finger of the handicapped person according to the present invention, a model showing the function of the finger of the handicapped person to be actually used, because the finger of the hand of the hand does not actually have nerves, holding the middle finger, ring finger, pinkie Forefinger uses only thumb and black to grab or pick up objects to make the most convenient life.

Figure 3 is a perspective view of the use of the wire control member of the handicapped for handicapped according to the present invention, the arm is cut arm inserted into the upper and lower guard 60 and lower protector 61 of the handicapped for the present invention of his side When the control plate 10 coupled to the first hinge part 50 by moving toward the upper arm guard 60 moves the wire control member 35 inserted into the first support 25 and the second support 26. The first wire 30 connected to the four connecting hooks 58 detects the frame 71 through the first guide slot 42 and the first spring 20 in the first guide tube 40 and the thumb frame 70. The thumb and index finger are pinched by the rotation of the second hinge portion 51 by being connected to the first connecting ring 55 in the).

Thumb and index fingertips (80) and the glove fingertips (90) portion of the thumb and forefinger is formed to be inclined in a straight line to face each other to be in close contact with each other.

The function is returned to the elastic force of the first spring 20, the third spring 22, and the fourth spring 23 for the rotary north ear.

Figure 4 is a perspective view of the state of use of the switch adjustment member of the handicapped for handicapped according to the present invention, the arm is cut arm inserted into the upper and lower guard 60 and lower protector 61 of the handicapped for disabled according to the present invention Moving toward the first hinge portion 50, the control plate 10 is moved toward the upper arm guard 60 to move the switch adjusting member 16, the switch 15 is connected to the power of the battery 77 the first motor The 75 is operated so that the second wire 31 is connected to the detection frame 71 through the second guide port 43 and the second spring 21 in the second guide tube 41 and the thumb frame 70. The thumb and the index finger are developed by the rotation of the third hinge portion 52 by being connected to the second connecting ring 56 which is present.

Thumb and index fingertips (80) of the index finger and the glove tip (90) portion is formed to be inclined in a straight line to face each other to be in close contact.
