Humans are trying to make a lot of convenience in daily life through the improvement of the working environment and the development of transportation and medical technology. However, many workers are still working in environments exposed to the risk of safety accidents, and the frequency of cutting accidents has not changed much compared to the past due to the increase in traffic accidents.

Rather, due to an increase in life expectancy and consequent increase in diabetes and peripheral vascular disease, the frequency of amputation patients has been increasing since decades ago in each country, and Korea is also on the rise.

Upper limb cleavage is less frequent than lower limb cleavage, but functional loss is large due to the loss of hand function. In particular, in the case of bilateral upper limb amputation that cannot receive the help of the healthy upper limb, the performance of daily life is severely restricted without wearing a prosthesis.

The wills that can be selected by the disabled with upper limb amputation can be broadly divided into aesthetic prosthetics, electronic prostheses, and hook prostheses. A cosmetic prosthesis is a method used for aesthetic purposes, and is a prosthesis with only the appearance of the hand without motor function. The electronic prosthesis works by using external power (battery) to hold and stretch the hand, and the operation sensor is a method that recognizes the movement of fine muscles as signals and operates. The number of hooks is a cable-controlled prosthesis, and the range and form of motion are the same as those of the former, but it is a method that uses the thoracic muscles without external power.

The above-described prosthetics have many difficulties in use in the case of activities necessary for daily life such as shaving, brushing teeth, eating, and working activities such as cutting, sawing, and hammering, in addition to the purpose of aesthetics or the purpose of holding and placing objects. For example, the number of hooks has a shape that makes it difficult to firmly support a product with a round handle shape, and it is difficult to fix it firmly by gripping an object only with spring tension. The electronic prosthesis has problems of discoloration, abrasion, and damage of the prosthesis cover when a lot of force is applied such as sawing and hammering, and there are factors that cause problems in the durability of the product such as finger bending and gear damage. In addition, there are many operations that can be implemented more stably in the case of the electronic prosthesis, but there is a problem with a high price.

Accordingly, both upper limb cuters can use them while replacing tools or tools themselves in daily life, work, and job performance, and there is a need for working prosthetics that can replace tools at a relatively inexpensive price.

It is not desirable to do it. The fixing part 221 may have a structure that is fixedly coupled to the fixing member 240 using a bolt or the like.

The structure of the detachable pin 210 will be described later for convenience of description.

Referring to FIGS. 1 and 2, the tool coupling part 300 includes a female connector 310 and a tool 320 coupled to the distal end of the female connector 310. The tool 320 refers to all items that a user can use in daily life, such as a hammer, a saw, a knife, a spoon, and a fork.

The rear end of the female connector 310 is open to have a hollow inside. The female connector 310 is formed with a circular fastening separation hole 311 in a vertical vertical direction. Since the inside of the female connector 310 is empty, the fastening separation hole 311 is formed in the upper and lower portions of the female connector 310 on a vertical line, respectively. The female connector 310 is coupled to or separated from the detachable pin 210 through the fastening separation hole 311. A detachment hole 312 is formed at the rear of the fastening separation hole 311. It is preferable to form a plurality of detachable holes 312 along the circumference of the female connector 310 at regular intervals.

A support groove 313 is formed on the rear inner surface of the detachable hole 312 from the rear end of the detachable hole 312 toward the front end. When there are multiple detachable holes 312, the support grooves 313 are formed as many as the number of detachable holes 312, and the support grooves 313 are located on the same line as the detachable holes 312 in the coupling direction.

4 and 5, the prosthetic coupling part 400 is a male connector 410 inserted and coupled in a direction from an open rear end of the female connector 310, and an angle adjusted to the rear of the male connector 410 It is configured to include a second coupling portion 430 coupled to the means 420 and the prosthetic arm 100 or the angle adjustment portion 500, the second coupling portion 430 may further include a rubber packing 440 .

The male connector 410 has an outer diameter corresponding to the inner diameter of the female connector 310. A hole (not shown) is formed in the front end of the male connector 410, and a pressing member 411 protruding and protruding by an elastic force through the hole is formed. The pressing member 411 is normally located in a form protruding outward from the front end of the male connector 410 through the hole, and when the male connector 410 is coupled to the female connector 310, the pressing member 411 is pressed against the detachable pin 210. ) Is in contact and the pressing member 411 moves to the inner rear side of the male connector 410. The front end of the elastic member 414 is coupled to the rear of the pressing member 411, and the rear end of the elastic member 414 is supported on the inside of the male connector 410. Accordingly, the pressing member 411 appears and protrudes through the hole by compression and expansion of the elastic member 414. The circumferential portion of the male connector 410 is formed with a coupling protrusion 412 that protrudes and protrudes along with the protrusion of the pressing member 411. Fastening holes 415 are formed in the upper and lower portions of the circumference of the male connector 410, respectively, and a ball-shaped coupling protrusion 412 that moves only in the vertical direction along the fastening hole 415 is coupled to the fastening hole 415. . That is, since the tip of the pressing member 411 has a hemispherical shape rounded in the tip direction and a radius gradually increases toward the rear, the rear of the pressing member 411 when the pressing member 411 is in a protruding position. As the outer circumferential surface pushes the coupling protrusion 412 in the vertical direction, the coupling protrusion 412 protrudes outward from the upper and lower portions of the male connector 410 along the coupling hole 415. However, when the pressing member 411 is inserted into the inner side of the male connector 410, the outer circumferential surface of the pressing member 411 having a small radius is located at the inner upper and lower portions of the coupling protrusion 412, so that the coupling protrusion 412 is As the supported part is released, the coupling protrusion 412 easily moves inward by a small force.

A support protrusion 413 is formed behind the coupling protrusion 412. The support protrusion 413 is inserted into the support groove 313 of the female connector 310 while maintaining the protruding shape when the male connector 410 is coupled to the female connector 310 so that the male connector 410 is inserted into the female connector 310 It supports it so that it does not move in the left and right rotation direction in the process of being combined with it. That is, when the male connector 410 is coupled to the female connector 310, the coupling protrusion 412 is inserted into the inner upper and lower portions of the female connector 310 along the support groove 313, respectively. Is located. At this time, since the male connector 410 and the female connector 310 are formed in a circular shape, the coupling protrusion 412 is not accurately coupled to the detachment hole 312 while the male connector 410 rotates, or the originally intended detachment hole 312 It may be coupled to the detachable hole 312 in a position other than this. Therefore, the coupling protrusion 412 and the support protrusion 413 located at the rear of the same line are caught in the support groove 313 and support the male connector 410 so that it does not rotate inside the female connector 310, so that the intended coupling It assists in enabling precise and quick engagement in position.

In a state in which the male connector 410 is coupled to the female connector 310, the coupling protrusion 412 moves to the inner side of the fastening hole 415, and then the pressing member 411 protrudes to the distal end and protrudes with the female connector 310. ) Is fastened to the detachable hole 312. On the other hand, the operation in which the coupling protrusion 412 appears and protrudes through the fastening hole 415 is related to the shape of the detachable pin 210.

Referring back to FIG. 3, the detachable pin 210 may be configured to gradually decrease in thickness from the bottom to the top. That is, when the male connector 410 is inserted into the female connector 310, the pressing member 411 is inserted into the inner side of the male connector 410 while contacting the outer circumferential surface of the detachable pin 210, so the detachable pin 210 The outer diameter of the lower part is the maximum. When the male connector 410 moves in the upper direction of the detachable pin 210, the outer diameter of the detachable pin 210 gradually decreases, so the pressing member 411 gradually protrudes in the tip direction again, and at this time, the coupling protrusion ( 412 has a structure that is coupled to the detachable hole 312 while protruding together.

Alternatively, the detachable pin 210 may be composed of a pressing part 211, a pressing release part 212, and a coupling release part 213.

When first inserting the male connector 410 into the interior of the female connector 211, the pressing member 411 comes into contact with the detachable pin 210, and the pressing member 411 is brought into the inner side of the male connector 410. This is the area to be pressurized. The pressing part 211 has an outer diameter corresponding to the inner diameter of the fastening separation hole 311.

The pressure release part 212 extends to the top of the pressure release part 211, and the rear (right side) shape of the pressure release part 212 is maintained as it is, and the front end (left side) to which the pressing member 411 is in contact is cut and the overall It has a thinner shape. That is, when the male connector 410 moves upward in a state coupled to the female connector 310, the pressing member 411 inserted into the male connector 410 can be re-reduced by the thinner thickness of the pressure release unit 212. It protrudes in the direction of the outer tip of the connector 410, at this time, the coupling protrusion 412 also protrudes and is coupled to the detachable hole 312. On the other hand, the connection portion between the pressing portion 211 and the pressure releasing portion 212 is connected by an inclined surface whose thickness gradually decreases in the upper direction.

The disengagement part 213 is connected to the upper part of the pressure release part 212 and is formed to gradually decrease in thickness from the lower part to the upper part.

Therefore, as shown in FIG. 5, the male connector 410 is inserted into the rear end of the female connector 310 while the tool coupling part 300 is coupled to the detachable pin 210 through the fastening separation hole 311 As the pressing member 411 comes into contact with the lower part of the detachable pin 210 and is inserted into the inner side, the male connector 410 and the female connector 310 are inserted in the state in which the male connector 410 is inserted into the female connector 310. It is a structure in which the pressing member 411 protrudes while moving to the top of the detachable pin 210 and the coupling protrusion 412 protruding at the same time is separated from the detachable pin 210 in a state coupled to the detachable hole 312.

In addition, when the tool coupling part 300 and the prosthetic coupling part 400 are separated, the combined male connector 410 and the female connector 310 are again coupled to the detachable pin 210 through the fastening separation hole 311. . At this time, the pressing member 411 located on the vertical line of the fastening separation hole 311 is in contact with the upper portion of the detachable pin 210, and the male connector 410 and the female connector 310 move to the lower portion of the detachable pin 210. As it moves, the pressing member 411 moves rearward along the outer surface of the detachable pin 210 and is inserted into the inner side of the male connector 410 again. When positioned at the bottom of the detachable pin 210, the coupling protrusion 412 is also inserted into the inner side of the male connector 410 and is completely separated from the detachable hole 312. In such a state, when the male connector 410 is pulled to the rear of the female connector 310, the tool coupling portion 300 and the prosthetic coupling portion 400 are completely separated.

The coupling and separating operation of the above-described tool coupling part 300 and the prosthetic coupling part 400 is performed by inserting the male connector 410 into the female connector 310 and pushing it forward while slightly lifting the tool coupling part 300 and The prosthetic coupling part 400 is coupled, and the conversely coupled tool coupling part 300 and the prosthetic coupling part 400 are combined with the detachable pin 210 and lowered to the rear and have a structural mechanism that is easily separated by pulling it backward. .

As shown in Figure 4, the angle adjustment means 420 is to adjust the left and right angle of the male connector 410, and includes an angle adjustment body 421, a left and right transfer screw 422 and a left and right transfer body 423 It is composed by

The angle adjustment body 421 is located at the rear of the male connector 410, and a transfer hole 421-1 is formed in the left and right direction in which the angle is adjusted. The transfer hole 421-1 has a shape that penetrates both left and right sides of the angle adjusting body 421, and has an open front and rear surface.

The left and right transfer screw 422 is rotatably coupled to the transfer hole 421-1, and a male thread is formed in the longitudinal direction at the circumference of the left and right transfer screw 422 located in the transfer hole 421-1. One side of the left and right transfer screw 422 is exposed to the outside of the transfer hole 421-1, and a rotating member 422-1 is formed at the exposed end. The rotating member 422-1 has a radius larger than the radius of the left and right feed screw 422, and the left and right feed screw 422 rotates according to the rotation of the rotating member 422-1. That is, in the case of the upper limb cutter, especially the upper limb cutter on both sides, since the angle cannot be adjusted by itself, the rotating member 422-1 is brought into contact with the floor or wall, and the left and right feed screw 422 is rotated forward or backward while rolling in the front and rear direction. Rotate. Therefore, it is preferable to further include at least one rubber ring 422-2 on the outer circumferential surface of the rotating member 422-1 to increase friction with the floor surface or the wall surface. It shows a state in which the rubber ring 422-2 is applied.

The left and right transfer body 423 is formed extending to the rear of the male connector 410. The left and right transfer body 423 may be formed integrally with the male connector 410, or may be formed as a separate body to be configured in a form of fastening to each other. When forming the male connector 410 as a separate body, the left and right transfer bodies 423 may be coupled to each other by forming a male and female screw connection structure. The left and right transfer body 423 is rotatably coupled to the angle adjustment body 421 within a certain angle. The middle portion of the left and right transfer body 423 is rotatably coupled to the front end of the angle adjustment body 421, and the rear end of the left and right transfer body 423 is coupled to the left and right transfer screw 422 located in the transfer hole 421-1. do. That is, when the left and right transfer screws 422 are fastened to the transfer hole 421-1 while the rear end of the left and right transfer body 423 is located inside the transfer hole 421-1, the rear end of the left and right transfer body 423 is It is fastened through. A female threaded line corresponding to the male thread of the left and right transfer body 423 is formed inside the rear end of the left and right transfer body 423. Therefore, as the rotating member 422-1 rotates forward and backward, the rear end of the left and right transfer body 423 moves to the left and right in the transfer hole 421-1 along the left and right transfer screw 422, and accordingly, the rear end is moved left and right. The male connector 410 coupled to the front end of the body 423 is a structure that moves left and right.

The second coupling portion 430 is formed at the rear end of the angle adjusting means 420, that is, the rear end of the angle adjusting body 421. A first coupling portion 110 corresponding to the second coupling portion 430 is formed at the distal end of the prosthetic arm 100. That is, the first coupling portion 110 is formed of a female or male threaded portion, and the second coupling portion 430 is formed of a male or female threaded portion corresponding to the first coupling portion 110. In the drawing, as an example, a bolt (not shown in the drawing) is applied to the second coupling part 430, and the second coupling part 430 is inserted into the distal end of the prosthetic hand 100 so that the bolt is fastened. (Not shown) was applied. At this time, when the prosthetic arm 100 and the prosthetic coupling part 400 are combined with only the male and female coupling parts, it is not easy to adjust the rotation angle of the prosthetic coupling part 400 in the fastened state, so the first coupling part ( It is preferable to further couple the rubber packing 440 between the 110) and the second coupling part 430. That is, when the first coupling part 110 and the second coupling part 430 are combined, the rubber packing 440 is compressed and the rubber packing 440 is in surface contact with each other to maintain a constant frictional force. When adjusting the rotation angle, it can be adjusted while maintaining a predetermined frictional force.

Meanwhile, at least one angle adjusting unit 500 may be further connected between the prosthesis coupling unit 400 and the prosthesis 100.

Referring to FIG. 6, the angle adjusting unit 500 has a structure in which the structure of the male connector 410 is omitted from the basic configuration of the prosthetic coupling unit 400. The second coupling portion 430 of the prosthetic coupling portion 400 is fastened to the position where the male connector 410 is coupled, and the rear end of the angle adjusting portion 500 is coupled to the prosthetic arm 100. That is, the angle adjustment unit 500 is composed of an angle adjustment means 510 and a second coupling unit 520 in a similar shape to the prosthetic coupling unit 400. Since the right and left rotation angle of about 35 degrees can be adjusted through the angle adjusting means 420 of the prosthetic coupling part 400, when the angle adjusting part 500 is additionally configured, the left and right rotation angle can be adjusted up to 70 degrees. .

On the other hand, it is preferable to have the above-described effect by interposing the rubber packings 440 and 530 respectively between the prosthetic coupling part 400 and the angle adjusting part 500 and between the angle adjusting part 500 and the prosthesis 100. .

The present inventors described above will be described the state of use of the prosthetic removal device for work capable of replacing the tool as follows (see FIGS. 5 and 7 ).
