Abstract: An anchor device serves for knot-free attachment of a tissue to a bone by means of at least one suture threaded through that anchor device. The device comprises an anchor body and a transverse bore for receiving a suture passing through said anchor body in a distal end region. The anchor body is provided with a longitudinal bore extending axially from a proximal end up to said transverse bore, and an axially displaceable clamping element is held in said longitudinal bore. An expanding element is provided for radially expanding at least one section of a wall surrounding said longitudinal bore.

Abstract: A medical instrument for grasping surgical suture material, with a shaft on whose proximal end a handle is positioned consisting of at least two gripping members and on whose distal end a tool is positioned consisting of a rigid jaw member and a pivotable jaw member and where the pivotable jaw member can be pivoted with respect to the rigid jaw member for opening and closing with a moveably configured gripping member of the handle, for which purpose the pivotable jaw member and the moveable gripping member are in active connection with one another by means of an actuating element mounted in the shaft. To create a medical instrument that is both easy to operate and makes possible a safe grasping and guiding of the suture material, it is disclosed that in the rigid jaw member there should be configured an indentation that opens toward the pivotable jaw member and that can be covered, with the tool in closed position, only in the center area by the pivotable jaw member.

Abstract: A medical instrument for cutting tissue has a tubular outer shaft having at least one outer shaft opening provided with at least one outer shaft blade. A tubular inner shaft is rotatable housed in the tubular outer shaft, the tubular inner shaft has at least one inner shaft opening provided with at least one inner shaft blade cooperating in a cutting action with said outer shaft blade. Said at least one inner shaft opening being curved and has a curved longitudinal central axis when viewed on a plane of projection running parallel to said rotation axis.

Abstract: A thread catcher for surgical sewing material consisting of a handle, a hollow shaft positioned on the distal side of the handle, and a catching device that is mounted so that it can be slid lengthwise within the hollow shaft by means of a drive element and whose distal end, which can slide out of the distal end of the hollow shaft, is configured as a catcher loop. To create a thread catcher for surgical sewing material that is simple to operate and ensures rapid and secure grasping of the surgical sewing material, it is proposed with the invention that the catcher loop should consist of at least three segments that re distally connected with one another.

Abstract: A device (10) serves to target and introduce bore channels into a tibia in the vicinity of a knee joint during reconstruction of the front cruciate ligament. It has a handle (12), a guide sleeve (18) removably attached to said handle, said guide sleeve having a longitudinal axis (44). A distal end of said guide sleeve (18) constitutes a first aiming point. An arm (28) protrudes from said handle (12). A distal end of said arm constitutes a second aiming point. A first opening (42) is provided in a distal end region of said arm, said opening (42) being in alignment with said longitudinal axis (44). A second opening (50) is provided in that distal end region of said arm, said second opening (50) is at a distance from said first opening (42).

Abstract: The invention relates to a surgical instrument system, which comprises a hollow shaft as well as a shaft-type instrument that can be inserted into the hollow shaft. To create a surgical instrument system that consists of a hollow shaft and of a medical instrument that can be inserted into the hollow shaft and that is both simple in construction and capable of a range of uses, it is proposed according to the invention that at least one cam that reduces the inside diameter of the hollow shaft should be positioned on the interior of the hollow shaft.
