    摘要： A target apparatus for aligning a surgical drilling instrument that includes a pointer mechanism for arranging at a location on a bone where a drilled hole that is to be formed is intended to emerge, a guide mechanism for guiding the surgical drilling instrument, and an adjustable connection mechanism with a first end, which is connected to the guide mechanism, and a second end, which is connected to the pointer mechanism. The adjustable connection mechanism comprises a first component, a second component and a locking mechanism. The second component is movable relative to the first component along a predetermined path. The first component is elastically deformable by the locking mechanism such that the second component can be locked relative to the first component by clamping.

    摘要： A device for providing an access opening in a body, in particular for a spinal operation, comprised of a tubular device body (12) that extends along a longitudinal axis (L) of a device body, said body having a distal end (14) that is to be positioned inside a body and a proximal end (16) that is to be positioned outside a body, wherein in the region of the proximal end (16) an optics-carrier arrangement (28) with a movable optics-carrier (36) is positioned or can be positioned to have a path of motion (B) about the longitudinal axis of the device body, characterized in that that the optics carrier arrangement (28) comprises a guideway element (30) that carries the optics carrier (36), said guideway element having a guideway region (34) that can be positioned by means of pivoting about a swivel axis (S) in an operating position in the region of the proximal end (16) of the device body (12).

    摘要： A medical instrument according to the invention has an elongate shank, and a tool which is arranged on a distal end portion of the shank and which comprises two tool elements interacting with each other, of which at least one tool element is movable by a longitudinally displaceable first transmission element. A distal end portion of the first transmission element has a surface inclined with respect to a direction of displacement, and the distal end portion of the shank, or an element connected non-displaceably thereto, has a mating surface which is inclined with respect to the direction of displacement and which, with the inclined surface, forms an interspace dependent on a displacement of the distal end portion of the first transmission element.
