Abstract

A surgical device for stabilizing tissue or positioning organs, or for positioning and holding surgical instruments and devices during a surgical intervention, includes a main body and a flexible arm. The flexible arm can be fastened to the main body, which can be brought into different positions and/or locations and which can be locked in a desired positioning by a tightening mechanism. The tightening mechanism can be tightened and/or released self-actingly and/or by an energy source. In a locked state of the flexible arm, the tightening mechanism has a retightening reserve, and the flexible arm can be automatically retightened in order to maintain its locked state, in particular by an introduction of energy from the energy source or self-actingly, by utilization of the retightening reserve. A retightening mechanism for use in the surgical device automatically retightens a flexible arm when in a locked state to maintain its locked state.
