Orthopedic joint device
An orthopedic joint device having a lower leg part, a foot part that is arranged on the lower leg part about a swivel axis such that it can be swivelled, at least a first energy store, and a coupling element. The coupling element can be brought into a coupling position, in which a swivelling of the foot part relative to the lower leg part about the swivel axis in a plantar flexion direction leads to an increase in the amount of energy stored in the first energy store, and a de-coupling position. The orthopedic joint device also has at least one release element, which can be brought into a release position and a locked position. The energy stored in the first energy store can be released by bringing the release element into the release position.
1. An orthopedic joint device comprising:
a lower leg part;
a foot part that is arranged on the lower leg part about a swivel axis such that the foot part is swivelled;
at least a first energy store;
a coupling element arranged in a coupling position, in which a swivelling of the foot part relative to the lower leg part about the swivel axis in a plantar flexion direction leads to an increase in the amount of energy stored in the at least a first energy store, and a de-coupling position;
at least one release element arranged in a release position and a locked position, wherein the energy stored in the at least a first energy store is released by bringing the at least one release element into the release position; and
an electric control system that is configured to bring the at least one release element out of the locked position and into the release position, and vice-versa.
2. The orthopedic joint device according to claim 1 , wherein the energy stored in the at least a first energy store cannot be influenced by the swivelling of the foot part relative to the lower leg part when the coupling element is in the de-coupling position.
3. The orthopedic joint device according to claim 1 , further comprising at least one pressure, position, force or acceleration sensor, which is configured to record at least one measured value and to transmit the at least one measured value to the electric control system.
4. The orthopedic joint device according to claim 3 , wherein the electric control system is configured to bring the at least one release element out of the locked position into the release position, depending on the at least one transmitted measure value.
5. The orthopedic joint device according to claim 3 , wherein the electric control system is configured to detect a loss of ground contact of the orthopedic joint device using the at least one transmitted measured value, and to bring the at least one release element out of the locked position into the release position when the loss of ground contact has been detected.
6. The orthopedic joint device according to claim 1 , wherein the electric control system is configured only to bring the coupling element from the coupling position into the de-coupling position when the at least one release element is in the locked position.
7. The orthopedic joint device according to claim 1 , further comprising a second energy store, which is configured in such a way that the swivelling of the foot part relative to the lower leg part about the swivel axis in a dorsal flexion direction leads to an increase in the amount of energy stored in the second energy store.
8. The orthopedic joint device according to claim 7 , wherein the at least a first energy store or the second energy store include a spring element or a hydraulic device or a pneumatic device.
9. The orthopedic joint device according to claim 8 , wherein two rotary hydraulics are allocated to the joint device.
10. The orthopedic joint device according to claim 1 , wherein the coupling element is designed as a fluid-valve combination.
11. An orthopedic joint device comprising:
a lower leg part;
a foot part that is pivotally mounted to the lower leg part about a rotation axis;
at least one energy store;
a coupling element arranged in a coupling position, in which a pivoting of the foot part relative to the lower leg part about the rotation axis in a plantar flexion direction leads to an increase in the amount of energy stored in the at least one energy store, and a de-coupling position;
at least one release element movable between a release position and a locked position, wherein the energy stored in the at least one energy store is released by bringing the at least one release element into the release position; and
an electric control system that is configured to bring the at least one release element out of the locked position and into the release position, and vice-versa.
12. The orthopedic joint device according to claim 11 , wherein the energy stored in the at least one energy store is independent of the pivoting of the foot part relative to the lower leg part when the coupling element is in the de-coupling position.
13. The orthopedic joint device according to claim 11 , further comprising at least one sensor, the at least one sensor including a pressure, position, force or acceleration sensor, the at least one sensor is configured to record at least one measured value and to transmit the at least one measured value to the electric control system.
14. The orthopedic joint device according to claim 13 , wherein the electric control system is configured to bring the at least one release element out of the locked position into the release position, depending on the at least one transmitted measure value.
15. The orthopedic joint device according to claim 13 , wherein the electric control system is configured to detect a loss of ground contact of the orthopedic joint device using the at least one transmitted measured value, and to bring the at least one release element out of the locked position into the release position when the loss of ground contact has been detected.
16. The orthopedic joint device according to claim 11 , wherein the electric control system is configured to bring the coupling element from the coupling position into the de-coupling position when the at least one release element is in the locked position.
17. The orthopedic joint device according to claim 11 , further comprising a second energy store, which is configured in such a way that the pivoting of the foot part relative to the lower leg part about the rotation axis in a dorsal flexion direction leads to an increase in the amount of energy stored in the second energy store.
18. The orthopedic joint device according to claim 11 , wherein the at least one energy store includes a spring element or a hydraulic device or a pneumatic device.
