A robot assembly includes at least four load-bearing structural parts connected by joints between each two adjacent structural parts to form a chain, and a joint motor associated with each joint for the driven movement of the structural parts connected by the joint relative to each other. A control device is provided in one of the structural parts which is connected at both ends to an adjacent structural part via an associated joint. The control device is designed to control at least three of the joint motors, and the electrical connection of the control device to each of the joint motors necessary for the controlling process is provided by a separate control line dedicated to the associated joint motor.

Robot assembly

A robot gripper includes a main gripper body that has a connection flange designed to secure the rotational gripper to a tool flange of a robotic arm; a base element that is mounted on the main gripper body such that it can rotate about a first rotational axis by a first rotational joint able to be adjusted automatically by a first drive motor; a first gripper finger mounted such that it can rotate about a second rotational axis aligned parallel to the first rotational axis, relative to the base element, by a second rotational joint which can be adjusted automatically by a second drive motor; and at least one additional gripper finger. The second rotational joint is configured to adjust the first gripper finger individually, using the second drive motor, independently of the at least one additional gripper finger.

A robotic surgery system includes a robot and an instrument assembly. The instrument assembly includes a drive unit with at least one rotary drive having an electric motor and a drive shaft that has a coupling part for coupling to a drive shaft of the instrument; an instrument including an instrument shaft and a drive shaft that has a coupling part for coupling to a drive shaft of the drive unit; and an instrument interface including a sheath that encompasses the drive unit. In order to detachably couple an instrument module to an instrument part of a surgical instrument, an electromagnet in a magnet assembly of the instrument module is activated or deactivated, a permanent magnet of said magnet assembly is moved into a locking position and/or an angular position of a coupled counter element assembly of the instrument part is detected by an angle sensor of the instrument module.

Robotic surgery system and surgical instrument

A surgical instrument arrangement has a modular motor drive unit which has a drive arrangement having at least one output element, an instrument shaft that can be detachably connected to the drive unit, and a drive arrangement having at least one input drive element. The output drive arrangement and the input drive arrangement can be coupled to each other by a mechanical interface that has at least one single-sided linkage, a pin, and a cut-out, wherein the pin can be radially expanded in the cut-out. Alternatively, a gap may be formed between the pin and the cut-out, which gap is wavy in the radial direction, and in which a radially displaceable, axially fixed intermediate element arrangement is arranged. The surgical instrument arrangement may also include a sterile barrier, which is provided to envelop the drive unit and to be arranged between the drive unit and the instrument shaft.

One aspect of the robotic surgery system according to the invention relates to a robot assembly comprising at least one robot and an instrument assembly comprising at least one instrument that is guided by said robot assembly. Said instrument assembly comprises at least one instrument housing having at least one drive unit housing part containing a cavity designed to hold the drive unit, said drive unit housing part having a seal for the sterile sealing of an insertion opening of the cavity in addition to a dynamic sterile barrier which delimits the cavity in a sterile manner and across which the drive train arrangement can be actuated; and/or the drive unit is offset laterally in relation to a longitudinal axis of the instrument shaft towards a connection between the instrument housing and the robot assembly.
