Abstract

A surgical robot/instrument system comprising a holding arm whose distal end portion has a gripping or holding device arranged thereon, the latter being designed to hold a trocar or a surgical instrument in an exchangeable fashion, and a surgical instrument with a minimally invasive design comprising an instrument shaft whose distal end portion supports an instrument tip via a joint, said instrument tip supporting an effector of the surgical instrument. The surgical robot/instrument system comprises drives by means of which functions such as actuating the effector, inclining or bending of the effector at its joint to the instrument shaft, rotating the effector around its longitudinal axis and/or rotating the instrument shaft, moving the instrument shaft in its shaft direction as well as moving the instrument shaft transverse to the shaft direction can be effected. The drives for effecting at least the instrument-internal functions, such as actuating the effector, inclining or bending the effector at its joint to the instrument shaft and rotating the effector around its longitudinal axis are provided internally on or in the surgical instrument. The drives for effecting the instrument-external functions, such as moving the instrument shaft transverse to the shaft direction, are provided externally on/in the holding arm.
