A surgical instrument with two legs movable relative to each other is provided. A tip inserted in a receiving space at the distal end of each leg is exchangeably held at the free end of the leg. A two part fixing device is provided for releasable fixation of the tip to the leg, the fixing device having on one of the parts two locking arms which are arranged next to each other and are elastically bendable apart, and on the other of the parts a locking projection extending into the leg transversely to the direction of insertion. The locking projection, when inserting the tip into the receiving space, engages between the locking arms, bending them apart, and at the end of the inserting movement, enters a recess on the inner side of the locking arms. The receiving space widens in the proximal direction from its insertion end.

In order to improve a surgical system for the preparation of an implant for filling a defect on a bone and/or a cartilage of a human or animal body formed as a result of a trauma and/or degeneration, so that the defect can be filled with the implant with as precise a fit as possible, it is proposed that the system enables a provided defect data file to be processed, which contains data in particular for the description of the shape, area and/or volume of the defect, and that the system enables the implant corresponding to the defect in shape and size to be prepared from at least one provided implant material using the defect data file. In addition, a method for filling a defect on a bone and/or cartilage of a human or animal body present as a result of a trauma and/or degeneration is proposed.

In order to connect the core undetachably to the holding element in the case of a pin-type holding element for an orthopaedic holding system with an elastically compressible, head-shaped widened portion and with a central opening, into which a core may be inserted, which prevents an elastic compression of the head-shaped widened portion by filling out the central opening in the region of the widened portion without expanding this, it is proposed that the core is displaceable in the opening between a locking position, in which it fills out the central opening in the region of the widened portion, and a release position plunging deeper into the central opening, in which it releases the central opening in the region of the widened portion and thus allows its elastic compression

In a suture anchor system for joining pieces of tissue, in particular, for repairing meniscal tears, comprising at least two arrow-shaped or pin-shaped anchor implants joined to one another by a flexible suture fastened to the anchor implants, in order to facilitate installation of the anchor implants, it is proposed that at least one of the anchor implants have a continuous longitudinal passageway for receiving a longitudinally displaceable core, that a suture guide for receiving a suture common to all anchor implants for longitudinal displacement in the suture guide be disposed on this anchor implant, that a clamping device for securing the suture in the suture guide be associated with the suture guide, and that the clamping device be inactive so long as the core is located inside the longitudinal passageway and only become active when the core is pulled out of the longitudinal passageway. An instrument for inserting such anchor implants is also described.

A device for introducing an endoscope or a surgical tool into body cavities with a feed for a flushing medium and an extractor for said flushing medium, which permits as versatile as possible an application of the endoscope or tool and maintains a higher pressure in the interior of the body as compared with the environment. The device includes a sluice, insertable into the body cavity from outside. The sluice has a cylindrical stem along whose inner wall extend two separate longitudinal grooves which have openings at their ends which pass through the wall of the stem. The openings outside the body are connected to the feed and the extractor for the flushing medium. A cylindrical endoscope or tool is inserted into the device with its outer wall tightly contacting the inner wall of the stem. The outer wall of the endoscope or tool, together with the longitudinal grooves of the stem, form sealed channels for the flushing medium.

A surgical instrument including a shank, at least one tool mounted for swivel movement at the end of the shank, a swivel element mounted for swivel movement about an axis of rotation for swivelling the tool between an open position and a closed position, and an actuating member actuatable from an end of the shank located opposite the tool for swivelling the swivel element about the axis of rotation. The high closing forces required for plastic deformation of objects can also be achieved without excessive forces being transmitted to the drive mechanisms. The actuating member is an arm which is articulatedly connected at a first articulation point to the swivel element, and that in the open position of the tool, the arm be at an incline to an axis of the swivel element extending perpendicularly to the axis of rotation through the first articulation point and in the closed position of the tool, be essentially perpendicular to the axis of the swivel element.
