Abstract: The present disclosure relates to a fast-action clamping device includes a handle including rod recesses, a tension rod and a link lever that can apply a fast-action clamping to a portion of an object that can have a rod-shaped from. The device is formed in that sections of an object may be received in the rod recesses and clamped in a clamping position without a clamping position of the link lever, set by a user, being able to pass into a non-clamping position. It also relates to a surgical device which includes such a fast-action clamping device.

Abstract: The present invention relates to a connection set for connecting a tool to a hand-held machine tool, which consists of, or comprises, a receptacle and an insert. The receptacle is designed provided and/or suitable to be fastened to a machine tool and to receive an insert. The insert is designed, provided and/or suitable for being fastened to the tool and for being releasably, at least in sections, inserted into the receptacle. In this, both the receptacle and the insert are continuous in the longitudinal direction and circumscribe each a lumen. Furthermore, the receptacle comprises one or several stationary pins projecting from an inner wall into the lumen and one or several movable pins. The outside of the insert comprises one or several guides, which are provided, designed or suitable for guiding the pins along the outside of the insert when inserting the insert into the lumen of the receptacle.

Abstract: The present invention relates to a surgical head holding device (1000) for use in a medical treatment. The head holding device (1000) encompasses hereby a head clamp (100). The head clamp comprises a first arm (101) and a second arm (103), wherein the first arm (101) as well as the second arm (103) comprise each a pin (101s, 103s), in order to receive or to clamp the head therein. Furthermore, the head holding device (1000) comprises a first bar (401) and a first connection arrangement (301) for connecting the first bar (401) to the head clamp (100).

Abstract: The arrangement is suitable in that sections of an object may be received in the rod recesses and clamped in a clamping position without a clamping position of the link lever, set by a user, being able to pass into a non-clamping position, in particular automatically. Sie betrifft ferner eine chirurgische Vorrichtung, welche eine solche Schnellspannvorrichtung aufweist. It also relates to a surgical device which comprises such a fast-action clamping device.
