Abstract

In the prosthetic with elbow bending means and finger bending means of the prosthesis, the upper and lower guards are combined by a rotatable hinge so that the elbows of the prosthetic elbow can be bent, and alternatively in two ways made by the prosthetic elbow bending. First, the finger bending means for selecting the first and third fingers and the third wire is connected to the first connecting ring and the first connecting ring to connect the thumb and forefinger so that the thumb and index finger can be curled. Connected to the fixed guide via the first guide tube, the wire control ring and the second guide tube, and second, the second connection of the wire connected to the middle finger, the ring finger and the little finger to bend the middle finger and the ring finger It is connected to the ring through the second passage and the Habakkuk 2 ring and connected to the 3rd link and the 3rd wire. It is connected to the fixing ring via the inner pipe.

The upper arm guard and lower arm guard is the elbow of the prosthesis, characterized in that the net and through-hole.

The present invention relates to the elbow of the prosthesis, the finger is bent by the elbow bending of the prosthesis to be more convenient for the wrist-cutting disabled person wearing the number of functional associated with Utility Model No. 349089 registered by the present applicant, You don't need the power to use electronics and batteries, and you can bend your finger by the elbow bending of your severed arm to catch the object.

The upper arm guard 12 and the lower arm guard 13 is the elbow of the prosthesis, characterized in that it is made of a mesh type and a through type.

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 made to solve the above problems, an 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, problems caused by sweat or moisture in the cut wrist part or elbow and the cuff part caused by wearing the prosthesis are solved by wearing the upper and lower guards of the mesh type and the through type.

In order to achieve the above object, the elbow bending means and the finger bending means of the prosthesis, the upper and lower guards are coupled to the hinge portion 10 that can be rotated so that the elbows of the prosthetic can be bent, the elbow bending of the prosthetic The finger bending means of the prosthesis which is alternatively selected by the two methods made by the first method, first, the wire connected to the thumb and forefinger is connected to the first connecting ring 52 so that the thumb and forefinger are bent and the first passage part 31 The first guide pipe 42, the wire control ring 43, and the second guide pipe 44 are connected to the third connecting ring 54 and the third wire 22 through the lower ring 1 and the lower ring 18. Second, the wire connected to the middle finger and ring finger and the little finger so that the middle finger and ring finger and the little finger can be bent through the second connecting ring 53 through the second passage 32 3rd link past Habakkuk 2 ring (19) It is connected to the 54 and the third wire 22 is connected to the fixing ring 40 through the first guide pipe 42, the wire control ring 43 and the second guide pipe 44.

The upper arm guard and lower arm guard is the elbow of the prosthesis, characterized in that the net and through-hole.

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 connected thereto, and is caught by the second catching 64.

When the latching portion 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.

2 is a shape of the mesh upper, lower protector of the present invention, the mesh 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 through-hole upper and lower lower guard of the present invention, the through-hole upper guard 16 and the through-hole lower guard 17 formed with a large number of through holes 25 are coupled to the hinge portion 10. .

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 portion of the prosthesis 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 prosthesis are made of a mesh and a through-hole to eliminate the inconvenience of sweat or moisture.

Made from lightweight materials, there is no resistance to prosthetic wear and wearing.

Simple function, no troubles such as failure or repair.
