Embodiment Construction

[0029] in figure 1 Shown therein is a front view of a prosthetic knee joint 1 with an upper part 2 with an upper connecting device 3 in the shape of a fixed tower. The upper connecting device 3 is used to fix the upper part 2 and thus the entire prosthetic knee joint 1 on a thigh tube not shown, and the prosthetic knee joint 1 is fixed to the prosthetic user through the thigh tube physically. The thigh tube is usually used to receive the thigh stump, and other fixation possibilities can also be provided. Generally, the thigh tube is provided with a substantially closed, open upper sleeve, into which the stump is inserted. Before inserting the stump, a so-called gasket (usually a silicone gasket) is put on the stump. Then the liner is inserted into the outer cylinder and folded at the upper edge of the outer cylinder, thereby creating a substantially airtight cavity on the outside of the liner and the inner side of the outer cylinder. The application of negative pressure can ...

Abstract

The invention relates to a prosthetic knee joint with an upper part (2) and a lower part (4) pivotably supported on said upper part (2), said upper part having an upper connection means (3), the The lower part has a lower connection means (5), wherein a vacuum pump (20) driven by the relative movement of the upper part (2) relative to the lower part (4) is assigned to the prosthetic knee joint, the The vacuum pump has an inlet (6) and an outlet (8).

Description

Technical field [0001] The invention relates to a prosthetic knee joint with an upper part and a lower part pivotally supported on the upper part, the upper part having an upper connecting device, and the lower part having a lower connecting device. The upper connecting device and the lower connecting device are used to fix the prosthetic knee joint on the components connected to the distal end and the proximal end. The lower connecting device is usually used for fixing on the calf tube, and the prosthetic foot is also fixed on the calf tube. These upper connecting devices or this upper connecting device are generally used to be fixed to the thigh tube, which is used to receive the thigh stump. Background technique [0002] In order to provide the prosthesis wearer with sufficient safety during the wearing of the prosthesis, the prosthesis needs to be reliably and fixedly arranged on the stump of the broken limb. The fixation by straps, hoses and buckles has the disadvantage th...
