Abstract
Disclosed is a ball-and-socket joint connection, in particular for a holding arm system for holding surgical instruments, with a joint ball sitting in a seat of a joint casing and permitting rotation in several axes and with a ball-shaped joint socket which can be axially displaced to and from the joint ball in a cylindrical section of the joint casing. A magnet is provided which produces a magnetic force between the joint ball and the joint socket such that they are drawn to one another. An actuation element is provided for displacing the joint socket and with this the joint ball is fixable in the seat of the joint casing by way of retracting the joint socket, wherein the joint ball by way of the magnet force is pressed into the seat of the joint casing, and wherein the joint ball by displacing forwards the joint socket with the actuation element is separable from the seat.
