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: A tool head for a surgical tool for knockout and/or insertion of prostheses is disclosed, comprising a tool body (10, 11, 12) having at least two clamping jaws (14, 14a, 14b, 14c, 15, 15a, 15b, 41) for clamping a prosthetic part, wherein at least one of the clamping jaws is mounted to be movable in relation to the tool body (10, 11, 12); wherein at least one of the movable clamping jaws has at least one pressure area (16), which is arranged so that applying a pressure to the pressure area (16) of the at least one clamping jaw causes a movement of the clamping jaws (14, 14a, 14b, 14c, 15, 15a, 15b, 41) toward one another or away from one another, to thereby clamp the prosthetic part between the holding areas of the clamping jaws.
