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.

A holding apparatus, in particular a holding arm and/or tripod, for medical purposes, comprises a proximal end for attaching the holding apparatus to a base and a distal end for receiving an add-on device; at least one first and one second arm segment, wherein the first arm segment is connected to a first joint and the second arm segment is connected to a second joint, wherein each joint is releasable and lockable; an operating device for releasing and/or locking the respective joint for putting the holding apparatus into a desired pose; and a first display unit which is arranged on the first joint and a second display unit which is arranged on the second joint. The first and/or second display unit is configured to display at least one status of the holding apparatus and/or of an add-on device that is different from the releasing and/or locking of the respective joint. The invention further relates to a method.

A displacement mechanism for placing an optical device onto a patient's eyes and removing the optical device from the patient's eyes when the patient is located in a patient bore of a medical imaging system. The mechanism includes a pneumatic device and a resilient element attached between an inner surface of the patient bore and the optical device wherein the resilient element extends through the pneumatic device and wherein the optical device is spaced apart from the patient's eyes in a first position. A pump inflates the pneumatic device to move the optical device to a second position wherein the optical device is placed on the patient's eyes. Inflation of the pneumatic device extends the resilient element and biases the resilient element to return to the first position. A vent valve vents air from the pneumatic device to return the optical device to the first position.

A method of placing an optical device onto a patient's eyes and removing the optical device from the patient's eyes when the patient is located in a patient bore of a medical imaging system having a confined headspace. The method includes providing a pneumatic device and a resilient element attached between an inner surface of the patient bore and the optical device wherein the resilient element extends through the pneumatic device and wherein the optical device is spaced apart from the patient's eyes in a first position. The pneumatic device is inflated to move the optical device to a second position wherein the optical device is placed on the patient's eyes. Inflation of the pneumatic device extends the resilient element and biases the resilient element to return to the first position. Air is vented from the pneumatic device to return the optical device to the first position.
