Embodiment Construction

[0045] exist figure 1 The orthopedic device in the form of a prosthesis of the lower extremity with a foot part 10 , a lower leg part 20 and a thigh part 30 is shown in a side view. The thigh member 30 is configured as a prosthetic barrel with a tube positioned for connection with the upper portion of the prosthetic knee joint. The lower leg part 20 has the lower part of the lower leg tube and the prosthetic knee joint and is connected to the thigh part 30 so as to be pivotable about the second pivot axis 23 . The foot part 10 with the prosthetic foot, which is inserted into the shoe, is connected to the lower leg part 20 so as to be pivotable about the first pivot axis 12 . The orthopedic device is in a straightened, maximally extended position. The first bracket 11 is rigidly fixed to the foot 10 . The first swing shaft 12 extends within the bracket 11 so that when the foot member 10 is flat on the floor, the lower leg member 20 can swing relative to the foot member 10 ab...

Abstract

The invention relates to an orthopedic device, comprising a foot part (10), a lower-leg part (20) and a thigh part (30). The foot part (10) is connected to the lower-leg part (20) for pivoting about afirst pivot axis (12) by means of an ankle joint (15). The lower-leg part (20) is connected to the thigh part (30) for pivoting about a second pivot axis (23) by means of a knee joint (25). The footpart (10) is connected to the thigh part (30) by means of a force-transmitting apparatus (40). The force-transmitting apparatus (40) causes a dorsal flexion of the foot part (10) in the event of a knee flexion over a first knee flexion angle range and causes a plantar flexion of the foot part (10) in the event of further knee flexion after a knee flexion limit angle ([alpha]Lim) has been exceeded.

Description

technical field [0001] The invention relates to an orthopaedic device comprising a foot part, a lower leg part and a thigh part, wherein the foot part is connected to the lower leg part via an ankle joint so as to be pivotable about a first pivot axis, and the lower leg part can be pivoted around a knee joint The second pivot shaft is pivotally connected to the thigh piece. Furthermore, the foot part is connected to the thigh part by means of a force transmission device. The orthopaedic device is designed in particular as a prosthesis or an orthosis. In the configuration as a prosthesis, the thigh piece is preferably configured as a thigh barrel for receiving the residual limb or as a prosthetic upper knee joint, with which the upper prosthetic knee joint can be connected. In the configuration of the orthopaedic device as an orthosis, at least one fixing device is arranged on the thigh part, by means of which the thigh part, eg a thigh splint or a thigh sheath can be placed ...
