Abstract
The invention relates to an orthopedic joint device having an upper part and a lower part which is hinged about a pivot axis to said upper part, having a flexion moment-controlled retainer device that is positioned between the upper part and the lower part, blocks a flexion and releases the flexion when a predefined flexion moment is exceeded, wherein a control element is associated with the retainer device and is coupled to a delaying element.
Claims21
An orthopedic joint device having an upper part and a lower part which is fastened to the upper part in an articulated manner about a pivot axis, with a flexion-moment-controlled retaining device which is arranged between the upper part and the lower part and which blocks flexion and releases the flexion when a predetermined flexion moment is exceeded, characterized in that the flexion-moment-controlled retaining device is assigned a control element which is coupled to a delay element which causes a time-delay activation of the control element, wherein the control element comprises a pneumatic or hydraulic actuator which is connected in terms of flow to at least one chamber, and wherein the control element comprises a spring-loaded actuator and the delay element comprises a valve or a throttle.
An orthopedic joint device having:
- an upper part;
- and
- a lower part which is fastened to the upper part in an articulated manner about a pivot axis with a flexion-moment-controlled retaining device which is arranged between the upper part and the lower part, and which blocks flexion and releases the flexion when a predetermined flexion moment is exceeded;
- wherein the flexion-moment-controlled retaining device is configured as a pneumatic or hydraulic damper device, and wherein the flexion-moment-controlled retaining device is assigned a control element which is coupled to a delay element, the delay element causes a time-delay activation of the control element, wherein the control element comprises a pneumatic or hydraulic actuator which is connected in terms of flow to at least one chamber, and wherein the control element comprises a spring-loaded actuator and the delay element comprises a valve or a throttle.
