Abstract
A support arm system (10) has at least one lockable articulated connection (16). A locking device (20) is associated with the articulated connection (16). The locking device (20) includes a passive drive (32) as well as an actuating device (36) associated with the locking device (20) with an active drive (38). The active drive (38) acts in the same plane as the passive drive (32).
Claims20
A support arm system comprising at least one lockable articulated connection with a pivot axis, the articulated connection comprising a locking device associated with the articulated connection, the locking device comprising:
- at least one brake shoe lever applying a braking force at the articulated connection, the braking force being applied perpendicular to the pivot axis;
- a passive drive, passively applying a passive drive force on the at least one brake shoe lever;
- and
- an actuating device associated with the locking device, the actuating device comprising an active drive applying an active drive force relative to the passive drive force, upon being actuated, wherein the active drive force acts in a same plane as the passive drive force and the braking force is applied in said same plane or in a plane which is parallel to said same plane and closely adjacent to said same plane.
A medical device system comprising:
- a medical device;
- and
- a support arm system connected to the medical device, the support arm system comprising a first arm segment, a second arm segment and an articulated connection connecting the first arm segment to the second arm segment and having a pivot axis, the articulated connection comprising a locking device associated with the articulated connection, the locking device comprising:
- at least one brake shoe lever applying a braking force at the articulated connection, the braking force being applied perpendicular to the pivot axis;
- a passive drive, passively applying passive drive force on the at least one brake shoe lever;
- and
- an actuating device associated with the locking device, the actuating device comprising an active drive applying an active drive force relative to the passive drive force, upon being actuated, wherein the active drive force acts in a same plane as the passive drive force and the braking force is applied in said same plane or in a plane which is parallel to said same plane and closely adjacent to said same plane.
A method for operating a support arm system comprising:
- providing the support arm system with at least one lockable articulated connection with a pivot axis, the articulated connection comprising a locking device associated with the articulated connection, the locking device comprising at least one brake shoe lever applying a braking force at the articulated connection, the braking force being applied perpendicular to the pivot axis, a passive drive, passively applying a passive drive force on the at least one brake shoe lever and an actuating device associated with the locking device, the actuating device comprising an active drive applying an active drive force relative to the passive drive force, upon being actuated, wherein the active drive force acts in a same plane as the passive drive force and the braking force is applied in said same plane or in a plane which is parallel to said same plane and closely adjacent to said same plane;
- and;
- providing an operating element for actuating a circuit component;
- and
- generating a control signal upon actuation of the operating element for actuating the circuit component wherein the active drive of the actuating device is activated by the circuit component.
