From early: = system and system, through continuous research and improvement, to the recent materials and shell products, the use of prosthetic limbs can be more comfortable. . Taking the lower arm limb of a human hand as an example, a small residual limb is usually reserved below the elbow joint. Therefore, as shown in the figure, the lower arm i of the prosthetic hand has an arm residual limb 2 that can be put on and set by the human body. The sleeve part u and the palm part 12 extending downward from the sleeve part U, thereby setting the lower arm of the prosthesis on the arm stump 2 so that the patient can use the hand f stump 2 to control and swing. No, while the lower arm of a human hand can be rotated relative to the upper arm, the lower arm 1 of the conventional prosthetic arm can only provide the patient with the arm stump 2 to control the lower arm of the prosthetic arm to swing forward and backward, so it cannot be used close to the natural function of the human body in use. Content] Therefore, the object of the present invention is to provide a rotatable lower arm device of the prosthetic hand, which can be used closer to the natural rotation function of the human arm. Therefore, the new rotatable lower arm device of the prosthetic hand is installed on the human hand. The stump of the lower arm includes an elbow unit, an arm arm table located below the elbow unit, and a transmission unit connected between the elbow unit and the arm unit. The elbow unit has a first Around the wall, and one The first surrounding space is 20 M253330: the surrounding space is formed by the first surrounding space for the lower limbs to pass through. The limb arms have a second surrounding wall and a second surrounding wall. The second accommodating space is provided for the lower limb stump to pass through. In addition, the transmission unit has-# provided at the near lower end edge of the first surrounding wall, and a set of 5 provided at the second A second sleeve member near the upper end edge of the wall, a set of connection pieces connected between the first sleeve piece and 4 second sleeve pieces, and a plurality of balls between each of the f sleeve pieces and the connection piece. Therefore, the stump of the lower arm is used to extend into the valley space and contact the second surrounding wall, so that the stump of the lower arm rotates 4. This linkage causes the second sleeve to rotate the second surrounding wall relative to the first surrounding wall. · 10 movements. The effect of this new model is that the second surrounding wall can be rotated relative to the first surrounding wall, so that the right + lower arm I can be placed closer to the human arm's natural rotation function when using the upper arm. [Embodiment] 15 Regarding the aforementioned and other technical contents, features and functions of the new model, one of the following reference drawings is compared with In the detailed description of the embodiment, it will be clearly understood. 丨 As shown in Figs. 2, 3, and 4, it is a preferred embodiment of the novel rotatable lower arm device of the prosthesis, which is installed on the stump of the arm below the human hand. 3 (shown in Fig. 4), the lower arm of the prosthetic arm includes an elbow unit 4, an extremity arm unit 5 located below the elbow unit 4, and an elbow unit 4 and an extremity. The transmission unit 6 between the arm units 5. The elbow unit 4 has a first surrounding wall 41 and a first receiving space 5 42 surrounded by the first surrounding wall 41 for the lower arm stump 3 to pass through. . And the limb arm unit 5 has a second surrounding wall 51 around the wall 5〗 F1, 4 Kuita's surrounding and pill can also be used for the second six of the lower limb stump. 6 There is a set of connecting pieces 61 on the second step of the upper step mountain chain step 61, a set of near second walls 42 near the second < brother of the second set of connectors 62,-connecting on the first -A connecting member 63 between the socket member 61 and the first disc member 62, a plurality of balls 64 between the socket members μ, μ :, the connecting member 63, and a plurality of positioning members. First, a set of connectors 61, 62 are ring-shaped, Ri Chu. And the first and second sets of connectors 6 and 62. ". First and second ring grooves 611 and 621 are formed, and the inner f-plane of the connecting member 6 corresponds to the first ring groove 6Π and the second ring groove 621, respectively: second and fourth ring grooves 63 and 632, thereby When the connecting piece 63 is connected to each of the sets Η and 62, each of the third and fourth ring grooved coffee and coffee beans respectively corresponds to the first ring groove 611'621 and the first chamber 633 and the chamber 634 'such balls 64 is respectively accommodated in each of the chambers 633, 63 < In addition, the connecting member 63 is further provided with two perforations 635 communicating with the third and fourth ring grooves 631 and 632, respectively, and through which the balls 64 can pass. The positioning member 65 is in the form of a bolt, and the perforation 635 is the form of a screw hole for the screw locking position of the positioning member. In addition, the lower arm of the prosthetic hand may further include a palm unit 7 provided at the lower end of the limb arm unit 5, and the palm unit 7 has a joint technology that can be engaged with the lower end edge of the second surrounding wall 51 by a combination of technical means such as flashing. The wrist part Η and a palm part 72 connected to the wrist part 71. As shown in FIG. 4, when the lower arm of the prosthetic hand is combined, the first and second sets of connectors 6 and 62 are respectively placed on the elbow unit 4 at the lower edge of the surrounding wall 41 J and the limb arm unit 5. The second surrounds the wall 51. At the same time, the driver will put the connecting piece 63 on the first and second sets of connecting pieces ... ⑽. The third and fourth ring grooves 63 and 632 points correspond to each other and constitute the first and the first. Spleen /… 611, 621 64g v Chengdi—chamber coffee, 634, and the balls 64 are put into the first and second chambers Θ33, 634 through the perforations 635, and hunting position 65 The screw is locked at the perforated coffee to achieve the sealing effect. If the combination of the lower arm device of the prosthetic hand is completed at this time, when the first and second surrounding walls 41 move in the opposite direction, the balls 64 are borrowed in the first and second furnace chambers M3. , 634 rolls to achieve the effect of relative rotation. The two-handed mouth as shown in Figure 5 'the lower arm of the prosthetic hand is combined with the lower limb stump 3, the upper section of the lower arm stump 3 will be located in the first accommodation space 42, and the: the section will be extended into the second In the accommodation space 52, when the lower arm stump 3 rotates, the lower arm stump 3 is used to link the second surrounding wall 51 and then driven by the transmission unit 6 to rotate relative to the first surrounding wall 41 as shown by the imaginary line in the figure, so that The lower arm of the prosthetic hand can be closer to the natural rotation function of the human arm in use. In addition, as shown in FIG. 6, in order to make the prosthetic lower arm device more beautiful to use, the prosthetic lower arm dress can further include a package 8 covering the outside of each unit 4, 5, 6/7, and the package 8 can be color-coded. And it is made of soft plastic shooting material, which can more closely resemble the shape of the human arm, avoiding the user's trouble of wearing short-sleeved tops in the summer because of the sleeves. Knowing the above, the new rotatable lower arm device of the prosthetic arm is connected to the transmission unit 6 between the elbow unit 4 and the limb arm unit 5 on the stump of the lower limb of the human limb and the limb arm unit 5, respectively, so that the limb arm unit 5 can be Rotate relative to the elbow unit 4, M253330 When the lower limb stump 3 rotates, it can be driven relative to the elbow unit by the transmission of unit 6: 5 'It can be closer to the natural rotation of the human arm when using the transmission ㈣: = Γ: Really achieves the above-mentioned purpose of the novel model.
