Abstract: A modular surgical instrument for knocking out or implanting a prosthesis that defines a prosthesis axis and which has a prosthesis neck includes a tool head with a passthrough for accommodating the prosthesis neck, a locking device for locking the mounted prosthesis neck, and a chuck, which has an axis for transferring a clamping force for the locking device. The passthrough and the chuck are arranged on opposite ends of the tool head relative to a lengthwise direction defined by the axis of the chuck, wherein the passthrough defines a passthrough axis which coincides substantially with the prosthesis neck axis when the prosthesis neck is locked in place. The axis of the chuck is at a distance from a plane defined by the lengthwise direction and the passthrough axis and/or is at a distance from a passthrough lengthwise axis that extends in the lengthwise direction and through the passthrough.

Abstract: A surgical trabecular tool for manipulating or removing bone tissue includes a tool body and at least one cutting element provided on the tool body. The cutting element includes a number of cutting edges arranged thereon, and the tool body is formed at least in part by a trabecular internal structure including a plurality of material struts forming a regular or irregular lattice structure which supports and connects the cutting elements.

Abstract: Surgical cutting tool for manufacturing of a recess in a firm body tissue, in particular in a bone and/or in a cartilage, with a milling range rotatable around a central axis of rotation, with an outside lateral surface and an internal area substantially defined by the lateral surface and turned away from the worked on body tissue. The lateral surface is formed with at least two machining cutting edges, which proceed at the lateral surface from a machining center to a machining edge of the milling range and which are in particular spiral curved. Apertures are arranged adjacent to the cutting edges for the transport of the cutting splinters into the internal area, whereby the cutting edges are interrupted by means of recesses in such a way that the cutting edges are formed by individually cutting elements.

Abstract: Surgical tool for knocking out and/or inserting of prostheses (1), in particular joint prostheses, in particular hip and/or shoulder prostheses, with in particular continuously curved head (2) of the tool, which exhibits a passage (3) for the seating of a prosthesis neck (4) and a bolt mechanism, which blocks detachably the neck (4) of the prosthesis in the passage (3), whereby the bolt mechanism exhibits an blocking element (5) intervening in the passage (3), which interference position is adaptable to different diameters of the neck (4) of the prosthesis, whereby an adjusting force is to be applied on the blocking element (5) by means of a adjustment member (6), where the manipulation of the adjustment member (5) is to be arranged by an adjustment element (7) outside of the operation field with distance to the blocking element (5).
