Abstract: A medical cutting instrument for cutting muscles and tendons, having a shaft on whose distal end a tool is mounted consisting of two jaw members, such that at least one jaw member can move with respect to the other jaw member, and on whose proximal end a handle is mounted, such that the movable jaw member and the handle operatively interact with one another by way of an actuation element mounted in the shaft in such a way that the movable jaw member can be shifted between a closed position and an opened position of the tool by actuating the handle and whereby the tool is configured for simultaneous severing and holding of one end of the severed muscle/tendon tissue. At least in the other jaw member, a guide is configured for controlled insertion of the muscle/tendon tissue that is to be severed.

Abstract: A tool according to the invention for generating an undercut in a bone including a core with a shank and a stamp mounted on a distal end of the shank, wherein the stamp, in a transition area to the shank, has a run-on bevel ascending in the distal direction, and a cutting sleeve which is arranged to be longitudinally movable on the shank and of which the distal end is formed by at least one segment that can be spread open when pushed onto the run-on bevel, wherein the at least one segment has at least one laterally arranged cutting edge. The invention also relates to a method for generating an undercut in a bone.

Abstract: A medical instrument serves for cutting off tissue and cartilage from a body. It comprises an outer shaft having at least a first window in a distal end area thereof. A hollow inner shaft is received within the outer shaft and can be rotated about a longitudinal axis of the outer shaft. The hollow inner shaft has at least one opening cooperating with the at least one window of the outer shaft in a cutting action when turning the inner hollow shaft. A further window is provided in the distal end area of the outer shaft which further window is surrounded by a curette having a separating edge. Tissue and cartilage separated by the curette can be cut into small pieces by the cutting edges of the rotatable inner shaft and then be sucked in through an opening of the inner hollow shaft.

Abstract: A device for preparing multiple channels in a bone comprises a handle, a single guiding sleeve mounted removable at said handle and an arm projected from said handle. Said single guiding sleeve comprises a central first guiding channel for receiving a first aiming wire, a second guiding channel for receiving a further aiming wire, said channels have parallel axes. At least one cannulation is provided, a central longitudinal axis thereof runs at a distance and parallel to the guiding channels. Said at least one cannulation being arranged offset in a circumferential direction to said second channel. An aiming wire introduced in said second channel can be replaced into a cannulation by pulling off the guiding sleeve turning it about the first aiming wire and reinserting the turned guiding sleeve into said handle.

Abstract: An apparatus for targeting and forming drill channels in the tibia in the area of a knee joint during reconstruction of an anterior cruciate ligament, having a handle, which includes a drill sleeve for configuring a first target point on the tibia and an arm extending beyond the distal end of the drill sleeve for determining a second target point on the tibial plateau. To provide an apparatus for targeting and forming drill channels in the tibia that is adaptable to the patient's individual anatomical idiosyncrasies, it is proposed that at least one portion of the arm should be configured as elastically reshapable.

Abstract: A medical puncturing serves for penetrating into a bone or a cartilage. It has a shaft and a tool carrier connected with its proximal end to a distal end of the shaft. The tool carrier has a puncturing tool being a punch or a multi-fracture chisel. The tool carrier is connected at its proximal end via a freely articulated joint to the distal end of said shaft. A stop limits a laterally pivoting movement of said tool carrier to a maximum angle of 45°.

Abstract: A medical cutting instrument for cutting muscles and tendons, with an instrument body that includes a handle on its proximal end and at least one cutting knife in the area of its distal end. To provide a medical cutting instrument that guarantees ease of handling and simple structure along with secure cutting of the muscle/tendon tissue, the instrument body should be of grooved configuration in the area of its cutting knife in such a way that the instrument body includes a hollow space extending in the longitudinal direction of the instrument body to receive and guide the muscle/tendon tissue that is to be cut, such that the instrument body includes an opening extending in the longitudinal direction of the instrument body and the cutting knife constitutes a side of the instrument body.

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 medical tool for removing tissue includes a removing device for the mechanical removal of tissue, and a magnet for the magnetic attraction and collection of magnetic or magnetizable particles.

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 are distally connected with one another.

Abstract: An anchor element serves for knotless fixing of a tissue to a bone by at least one suture threaded through the 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 the 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 movable within the body towards that transverse bore.

Abstract: A medical tool for removing tissue includes a removing device for the mechanical removal of tissue, and a magnet for the magnetic attraction and collection of magnetic or magnetizable particles.

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.
