Abstract

Various embodiments include a fastening unit for fastening a tendon to a system. The fastening unit comprises: a head with a first opening; a shaft with a second opening and an external thread; and a channel extending from the first opening along the head to the second opening at least partly along the shaft. The external thread and the channel in each case accommodate the tendon.

First claim

What is claimed is:

1. A fastening unit for fastening a tendon to a system, the fastening unit comprising:
a head with a first opening;
a shaft with a second opening and an external thread;
a channel extending from the first opening along the head to the second opening at least partly along the shaft;
wherein the external thread and the channel in each case accommodate the tendon; and
a counterpart with an internal thread for fastening the tendon to the system;
wherein the counterpart engages the shaft;
wherein, if the shaft engages the counterpart, the tendon is tightened; and
wherein if the shaft is disengaged from the counterpart, the tendon is disengaged.

2. The fastening unit as claimed in claim 1 , wherein the external thread is disposed on an end region of the shaft.

3. A fastening unit for fastening a tendon to a system, the fastening unit comprising:
a head with a first opening;
a shaft with a second opening and an external thread; and
a channel extending from the first opening along the head to the second opening at least partly along the shaft;
wherein the external thread and the channel in each case accommodate the tendon; and
wherein the shaft includes two external threads arranged on opposite end regions of the shaft.

4. The fastening unit as claimed in claim 3 , wherein the two external threads have different diameters.

5. The fastening unit as claimed in claim 1 , wherein the fastening unit is produced at least in part by a 3D-printing method.

6. The fastening unit as claimed in claim 1 , wherein the head and the shaft comprise a bolt.

7. The fastening unit as claimed in claim 1 , further comprising a drive unit driving the fastening unit in a first direction.

8. A tendon-driven system comprising:
a tendon arranged on a system;
a fastening unit for fastening the tendon to the system, the fastening unit comprising:
a head with a first opening;
a shaft with a second opening and an external thread; and
a channel extending from the first opening along the head to the second opening at least partly along the shaft;

wherein the external thread and the channel in each case accommodate the tendon; and
a drive unit for driving the system in a first direction;
wherein if the drive unit is driven, the shaft engages in a counterpart and the tendon is tightened; and
wherein if the drive unit is not driven, the shaft disengages from the counterpart and the tendon is disengaged.
