Patent number: 10350023Abstract: 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.Type: GrantFiled: May 31, 2016Date of Patent: July 16, 2019Assignee: SENSODRIVE GMBHInventors: Norbert Sporer, Matthias Haehnle

Patent number: 7109678Abstract: In a holding arrangement (101) for a medical-optical instrument (103), an electric motor is provided in a rotational joint (111, 119) to compensate a load torque occurring in this rotational joint. This electric motor is supplied with current in correspondence to a detected position of the rotational joint (111, 119). A current control curve required for this purpose is stored in a memory. This current control curve can be determined in that the rotational joints are deflected with the electric motor into predetermined positions and the current demand needed therefor is detected.Type: GrantFiled: June 30, 2004Date of Patent: September 19, 2006Assignee: Carl-Zeiss-StiftungInventors: Martin Kraus, Hartmut Gärtner, Martin Poxleitner, Michael Wirth, Alfons Abele, Roland Brenner, Norbert Sporer, Matthias Hähnle
