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.

Abstract: A medical instrument for cutting tissue has a tubular outer shaft, which comprises at least one window in the region of its distal end. The medical instrument further comprises a tubular inner shaft which is rotatable about a longitudinal axis and housed in the outer shaft and which has at its distal end a window arranged in the region of the at least one window of the outer shaft and provided with at least one cutting element. The medical instrument has a fixing element for unrotatably holding of the inner shaft relative to the outer shaft in a preset position. The fixing element is irreversibly detachable through rotational movement of the inner shaft.

Abstract: A device serves for guiding a drilling tool for forming a second bore in a bone, which second bore intersects an already existing first bore. A frame, having a first end and a second end has a rod-shaped body arranged at its first end. Said rod-shaped body is designed to be inserted into said already existing first bore. A guide sleeve is arranged at said second end of said frame and has a longitudinal axis intersecting said rod-shaped body in an area of its distal end. A fixing device is provided at said guide sleeve, said fixing device protrudes distally from said guide sleeve, said protruding fixing device can be placed on a body of a patient to be treated in an area where said second bore is to be formed.

Abstract: A device serves for introducing an anchor element into a bone. A loop of a thread extends laterally from said anchor element. Said device comprises an elongate body having a distal end which can be inserted into said anchor element in a rotationally locked manner. A distal end portion of said elongate body has at least one cutting for inserting said loop protruding laterally from said anchor element. Said cutting being designed in such a way that said loop when inserted into said cutting is prevented from falling laterally away. Said elongate body further has a longitudinally extending recess in an area of said cutting. Said recess is designed as an opening extending right through said elongate body, such that said loop inserted into said cutting can be gripped from the outside.

Abstract: A device serves for blocking a tendon graft in a drilled hole. An element is connected to said tendon graft which can be expanded radially. The element has a cylindrical body which is divided by an oblique cut into two wedge-shaped bodies initially connected to one another via a predetermined break point.

Abstract: A partial aiming device for targeting an arthroscopic operation site for a medical intervention, with a circularly arcuate element and with a first, radially extending aiming rod which can be moved along the circularly arcuate element. It is proposed that on the circularly arcuate element there is a connecting device by means of which a medical instrument with a shaft can be connected to the partial aiming device in such a way that the shaft is orientated as a second aiming rod that extends radially towards the first aiming rod.

Abstract: A medical instrument for cutting tissue comprises a tubular outer shaft which, in the area of its distal end, has at least one window with at least one blade, and further comprises a tubular inner shaft which is rotatable about a longitudinal axis, is received in the outer shaft and has, at its distal end, a cutting element which is arranged in the area of the at least one window of the outer shaft and is provided with several circumferentially arranged openings, each of the openings of the cutting element having at least one blade which, when the cutting element is moved in rotation, cooperates in a cutting action with the at least one blade of the outer shaft. It is proposed that at least some of the openings of the cutting element should have different widths, seen in a circumferential direction.

Abstract: An anchor element serves for knotless fixing of a tissue to a bone by means of at least one suture threaded through said anchor element. A body of that anchor element has an outer surface with projections. A transverse bore is arranged in a distal end section of said body for receiving a threading passing therethrough. A clamp element serves for clamping the suture threaded transversely through the bore. The clamping element has a portion arranged within the body and is movably within the body towards that transverse bore.

Abstract: A device for punching out tissue areas from bone has a blade whose circumferential cutting edge corresponds to the contour of a tissue area that is to be punched out. The blade is composed of a plurality of blade segments that are each movable in an axial direction counter to the force of a spring.
