RETAINING DEVICE FOR AN INSTRUMENT

摘要

The invention relates to a retaining device for an instrument, comprising at least one joint having at least two parts that can be moved relative to each other and at least one drive unit associated with the joint. The drive unit is designed to move the joint by driving at least one of the parts of the joint that can be moved relative to each other. The retaining device also comprises a securing device, which has a locking mechanism associated with the joint and a release unit that can be activated, wherein the locking mechanism interacts with the release unit in such a way that the locking mechanism holds the joint in a locked position as long as the release unit is not activated. The securing device is designed to permit a motion of the joint out of the particular locked position within a specified range of motion even if the release unit is not activated. The invention further relates to a corresponding securing device for a retaining device and to an operating method for said securing device.

1. A retaining device for an instrument, comprising:
a securing mechanism including:
at least one joint, with at least two parts which are movable relative to one another;at least one drive unit; anda lock assigned to the at least one joint and with a release unit adapted to be selectively activated, the lock being configured to hold the at least one joint in a locking position so long as the release unit has not been activated, the at least one joint being assigned to the at least one drive unit, and the at least one drive unit being configured to move the at least one joint by driving at least one of the parts of the at least one joint which are movable relative to one another, wherein: the securing mechanism is configured to permit a movement of the at least one joint out of the respective locking position within a predetermined range of movement even when the release unit has not been activated to enable vibration damping, in a case where the release unit has not been activated and the lock has been disengaged, the securing mechanism limits the movement of the at least one joint to the predetermined range of movement, and in a case where the movement of the at least one joint departs from the predetermined range of movement, the securing mechanism activates the lock.
