Description

An elbow of artificial limb}

The present invention relates to the elbow of the prosthetic arm, more specifically, in the elbow of the prosthesis (義 手) consists of the elbow bending means and finger bending means of the prosthetic arm, the upper arm guard and lower guard to bend the elbow of the prosthesis The two ways of the finger bending means coupled to the hinge portion 10 is formed by the elbow bending of the prosthesis, First, the wires connected to the thumb and index finger so that the thumb and index finger can be bent first connection Connected to the third connecting ring 54 via the first passage 31 and the lower ring 1 ring 18 by the first wire 20 connected to the ring 52 and coupled to the first connecting ring 52. And connected to the fixing ring 40 by passing through the first guide pipe 42, the wire control ring 43, and the second guide pipe 44 by the third wire 22 connected to the third connecting ring 54. Second, stop, ring finger, pinkie can be bent The second passage part 32 and the lower night 2 by the second wire 21 connected to the second connecting ring 53 and coupled to the second connecting ring 53, respectively. The first guide pipe 42 and the wire control ring 43 and the third cable are connected to the third connecting ring 54 via the ring 19 and connected by the third wire 22 connected to the third connecting ring 54. It is connected to the fixing ring 40 through the guide pipe 44.

The upper arm guard and the lower arm guard is made of a net shape, the elbow of the prosthesis, characterized in that also made of a space portion with a space.

In general, the wrist-disabled people with disabilities have been inconvenient economically and timely due to frequent breakdowns and difficult repair problems when using prostheses using chemical or electrical energy.

The present invention has been devised to solve the above problems, the object of the present invention is a simple prosthesis that allows five fingers to be bent by the elbow bending of the prosthesis worn by the disabled person with his wrist cut below the elbow.

In addition, a lot of sweat or moisture in the cut wrists, elbows and cuffs caused by wearing the prosthetic hand was solved by wearing the upper and lower body guards of the mesh and space shape.

In order to achieve the above object, the present invention is composed of the elbow of the prosthesis (義 手), the elbow bending means and the finger bending means of the prosthesis, the upper arm guard and the lower guard to rotate the elbow of the prosthesis is rotated The prosthetic finger bending means of the two ways coupled to the possible hinge portion 10 and made by the elbow bending of the prosthesis is, firstly, a wire connected to the thumb and forefinger so that the thumb and forefinger can be bent, the first connecting ring ( 52 connected to the third connecting ring 54 through the first passage 31 and the lower ring 1 ring 18 by the first wire 20 coupled to the first connecting ring 52 and the first connecting ring 52. It is connected to the fixing ring 40 by passing through the first guide pipe 42, the wire control ring 43 and the second guide pipe 44 by the third wire 22 connected to the three connection ring 54, Second, stop, ring finger, stop finger, ring finger to bend, Each of the wires connected to the little finger is connected to the second connecting ring 53, and the second passing part 32 and the lower night ring 2 are connected by the second wire 21 coupled to the second connecting ring 53. The first guide pipe 42, the wire control ring 43, and the second guide pipe 44 are connected to the third connecting ring 54 by the third wire 22 connected to the third connecting ring 54. It is connected to the fixing ring 40 through).

The upper arm guard and the lower arm guard is made of a net shape, the elbow of the prosthesis, characterized in that also made of a space portion with a space.

Hereinafter, the present invention will be described through preferred embodiments.

1 is a perspective view of a finger movement by elbow bending according to the present invention, the upper and lower guard 12 and the lower guard 13 is coupled to the hinge portion 10 that can be rotated.

In order to bend the thumb and forefinger, wires respectively connected to the thumb and forefinger are connected to the first connecting ring 52, and the first passage part is connected by the first wire 20 coupled to the first connecting ring 52. 31 and the first guide pipe 42 and the wire control ring by a third wire 22 connected to the third connecting ring 54 through the lower ring 1 18, and connected to the third connecting ring 54. Passing through the 43 and the second guide tube 44 is connected to the fixing ring 40 to the first elastic member 48.

In addition, the fourth wire 23 coupled to the first connecting ring 52 is connected to the locking portion 63 of the first latch and is caught by the first latch 62.

To connect the middle finger, ring finger, and little finger, the wires connected to the middle finger, ring finger, and little finger are respectively connected to the second connecting ring 53 and to the second wire 21 coupled to the second connecting ring 53. The first guide pipe (3) through the second passage 32 and the lower ring 2 (19) by the third wire (22) connected to the third connecting ring (54), connected to the third connecting ring (54) 42 and the wire control ring 43 and the second guide tube 44 to the first elastic member 48 is coupled to the fixing ring 40.

In addition, the fifth wire 24 coupled to the second connecting ring 53 is connected to the catching portion 65 of the second catching portion and is caught by the second catching 64.

When the hook 65 of the second latch is pulled and hooked to the rear of the second latch 64, the middle finger, the ring finger, and the little finger are bent and held by the fifth wire 24.

By pulling the stopper 65 of the second latch, the middle finger, ring finger, and little finger is bent and fixed, it is more effective to use only the bending means of the thumb and index finger by elbow bending.

Figure 2 is a shape of the upper mesh net, the lower protector of the present invention, the mesh upper upper protector 14 and the mesh lower protector 15 is coupled to the hinge portion (10).

There is a net guard 11 between the net and the net so that the shape of the net upper guard 14 and the net lower guard 15 is maintained.

3 is a view showing the upper and lower guards formed with a space portion of the present invention, the space-type upper arm guard 16 and the space-type lower arm guard 17 formed with a large number of spaces 25 are hinge portions 10. Are combined.

Figure 4 is a perspective view of the wrist function in the manner of Figure 1 of the present invention, five fingers are bent by the bending of the elbow.

The wrist support 50 and the palm frame 35 are rotated by the rotation of the cut wrist end 70 of the cut wrist and the wrist rotating disc part 30 of the right hand coupled with the palm frame 35 is rotated, and the whole wrist is rotated. Will rotate.

Wrist rotation disc portion 30 is coupled by a hook 33 at the lower end of the lower protector (13).

The wrist of the prosthetic hand rotates only as much as the margin of the rotary space portion 34 at the lower end portion of the wrist rotating disk 30 and the lower protector 13 and returns to its original position by the second elastic member 49.

Glove finger joint position of the prosthetic wrinkles 68 is formed is a smooth bending of the finger.

As described above, the five fingers are bent and the wrist is rotated by the rotation of the elbow and the cut wrist portion of the arm worn by the prosthetic arm.

In addition, the lower and upper arm guards forming the elbow of the prosthetic elbow are made of a net shape and made up of a large number of spaces to eliminate the inconvenience of sweat or moisture.

Made from lightweight materials, there is no objection to wearing clothes.

Simple function, no troubles such as failure or repair.
