A holding device for surgical instruments, in particular for minimally invasive surgery, is provided. The device includes a holding arm that holds an instrument support at the distal end of the holding arm. The instrument support can have which a surgical instrument is mounted thereon. The surgical instrument is operated by way of a drive device. To permit a simple replacement of the instrument support, the drive device is connected to the holding arm by way of a holding device, such that the drive device can easily be changed from a drive position to a replacement position.

Holding device for a surgical instrument

Minimally invasive instrument for robotic surgery including a functional element, a force, torque and/or pressure transmission device for transmitting force, torque and/or pressure from a drive to the functional element, a coupling device for coupling the instrument to a medical robot such that the functional element can be actuated by the drive, wherein an operating element for manually operating the functional element in a state in which the instrument is uncoupled from the medical robot.

Minimally invasive instrument for robotic surgery

A surgical manipulation instrument which is particularly suitable for minimal invasive surgery, comprising an extra-corporeal drive device to which several axially displaceable first actuation elements are connected. The disclosure also relates to a partial intra-corporeal manipulator part which comprises several axially displaceable second actuation devices for actuating an end effector. Pairs of actuation elements are detachably connected together by means of a coupling device. A pivotable intermediate element is provided between the second coupling element and the second actuation element.

Surgical manipulation instrument

A robot structure, in particular for minimally invasive surgery, is provided with a first robot element and a second robot element that can be moved relative to the first robot element, said second robot element having two grasping and/or cutting elements which can be uniformly moved with respect to each other and which are connected to the first robot element via a hinge axis. The robot structure further has a force transmitting device for moving the grasping and/or cutting elements of the movable robot element and at least one sensor element comprising a sensitive end for receiving forces and/or torques that occur on the movable robot element and includes a base element that is fixed to the first robot element.

A force/moment sensor for measurement of three orthogonal forces and three orthogonal moments, comprises an inner holding element which is surrounded by an outer holding element. The two holding elements are connected to each other by deformation elements. For each deformation element, at least one deformation transducer is provided. The force/moment sensor is preferably monolithic, and the deformation transducers, formed as strain gauges, are preferably arranged in one plane or in two preferably parallel planes.

Force/moment sensor for measurement of forces and moments

A surgical manipulation instrument which is particularly suitable for minimal invasive surgery, comprising an extra-corporeal drive device and a partial intra-corporeal manipulator part. The drive device comprises several axially displaceable first actuation elements. The first actuation elements are detachably connected to axially displaceable second actuation elements, by a coupling device, the second actuation elements being used to actuate an end effector. The coupling device comprises two coupling elements, one of the coupling elements having undercut recesses in which the second coupling element engages.

A robot structure, suited especially for minimally invasive surgery, comprises two robot elements interconnected by a hinge. Using a force transmission the movable robot element of said robot structure, notably comprising two gripping elements, can be moved. A sensor element is provided for picking up forces occurring. To reduce the influence of motional forces, said force transmission is connected with a base element of said sensor element such that motional forces transmitted by said force transmission element are supported at the base element.

A surgical robotic system includes a robotic arm, an end effector movably connected thereto and provided with a movable end effector element driven by an actuator, and a force sensor arranged between the robotic arm and the end effector. The actuator is formed by a hydraulic cylinder. The robotic arm is provided with a hydraulic line connected to said hydraulic cylinder of the end effector.
