Embodiment 1

[0022] as attached figure 1 As shown, the inner collar 1 is directly fixed on the residual limb, and the outer sleeve 2 is sleeved on the inner collar 1, and is connected with bolts 3 on the left and right symmetrical axes. The inner collar 1 takes the connecting bolt 3 as the center line, and the upper edge of the rear semicircle is provided with steps, and the upper edge of the front semicircle is free of obstacles, so that the outer sleeve 2 can only be lifted upwards after being stressed, and cannot be turned backwards. The lower end of the outer sleeve 2 is connected with the upper end of the prosthesis 4 .

[0023] This automatic striding device 5 heads are annular. Be fixed on the rear semicircle upper mouth edge of the inner sleeve ring 1, and the stride distance adjusting bolt 6 is provided with a round hole, and the supporting nut is fixed on the outer sleeve 2; Step distance adjustment bolt 6 is flexibly connected in two round holes, and two ends are provided with...

Embodiment 2

[0029] as attached figure 2 As shown, the automatic striding method has been introduced in Embodiment 1, and the striding method of the prosthesis wearer with high amputation of both legs is completely consistent with the automatic striding method described in Embodiment 1.

Embodiment 3

[0031] as attached image 3 As shown, it has been introduced in Embodiment 1 that when the prosthesis 4 is upright, the head of the calf power pin 16 is on the same spherical surface as the outer hemisphere 15, and the calf of the prosthesis 4 can bend now.

[0032] When the prosthesis 4 is in an upright position, sit down, and loosen the cross-legged rotating device 12 and the adjustable fixed pin 14 of the inner hemisphere 13 of the knee joint after sitting, so that the shank of the prosthesis 4 can be rotated and put on the good leg. This function not only enables the prosthesis wearer to sit on the spot, but also can change shoes and socks at any time.

Abstract

A simulated multifunctional prosthesis can not only overcomes physical defects of the disabled but help the disabled find themselves before amputation and feel regaining after prosthesis installation. For all the lower-limb disabled, the disabled can walk like normal people after installation of the prosthesis. Proper functions of the thigh can be simulated on the prosthesis, the lever principle and pressure of compressed springs can be applied on the amphiarthrosis, the purpose of automatic walking is achieved by means of shifting of weight, and the defect that existent prosthesis depends on stump muscle force is overcome. The amphiarthrosis is a neo-arthrosis additionally arranged at the root of the stump thigh and can enable the prosthesis to automatically walk and correct instable walking of a cripple, which is the core function of the prosthesis. The novel intelligent automatic walking prosthesis causes no pain and is easy to balance during walking. Crutches can be abandoned and the disabled with the prosthesis can sit on the spot. Besides, the novel intelligent automatic walking prosthesis is applicable to all the lower-limb disabled and help paraplegia people walk.

Description

technical field [0001] The invention relates to a method for driving artificial limbs to automatically stride by using the combination of lever principle and spring pressure, in particular to a new type of intelligent artificial limbs for automatic strides. Background technique [0002] Prosthetics are also called artificial limbs. The prosthetics in the initial period were stick-type, and after the lower leg was amputated, a stick could be tied to walk. After hundreds of years of innovation, prosthetics are not what they used to be, especially the artificial arms and hands imitated by the application of "sensing technology" on the upper limbs. Careful identification is difficult to see which is real and which is prosthetic. However, the lower limbs are not optimistic. For so many years, there have been innovations in the "knee joints", "soles of the feet" and sitting and standing postures, and there are no new tricks other than that. Whether the existing prosthetics are ...
