Abstract: A medical instrument comprises a shaft, a handle connected to said shaft and having a movable gripping part. An insert is guided along said shaft and connected to said movable part at its proximal end. A tool is provided at a distal end of said insert. A lock is provided for locking said movable grip part in a position. A detent is provided for releasing said locking of said lock. A rotatable stopping member is arranged on said movable grip part. A rotational plane of said rotatable stopping member lying across a longitudinal axis of a movement direction of said movable grip part. Said rotatable stopping member can be rotated between a first position not influencing said locking function of said lock and a second position keeping said lock permanently away from said locking engagement.

Abstract: A medical instrument comprises a shaft which is connected at the proximal end to a handle, and it also comprises an insert which is guided along the shaft and which is connected at the proximal end to a movable grip part of the handle. At its distal end, the insert has a tool which can be actuated by pivoting of the grip part. A lock is also provided which can be brought into locking engagement with the movable grip part. To cancel the lock function, a detent is provided which can be brought between lock and movable grip part, such that the lock function can be cancelled by the detent.

Abstract: The invention relates to a medical instrument having on its proximal end a shaft with a handle consisting of two gripping members and on its distal end a tool consisting of two jaw members and in which, to open and close the tool, at least one jaw member can rotate with respect to the other jaw member around a point of rotation by means of a push-pull rod and in which the push-pull rod is connected on the proximal side with a rotatable gripping member of the handle. To produce a medical instrument that can be used even in closely confined spaces and with sufficient transmission of force, it is proposed with the invention that the point of rotation should be configured as a variable, virtual point of rotation that is dependent on the position of the jaw members to one another.

Abstract: A medical instrument comprises a shaft whose distal end is bendable. Arranged at the proximal end of the shaft there is a handle on which a bend control mechanism for controlling the bending movement is arranged. The bend control mechanism has a pivotable control element. The pivotable control element runs over a friction element, and an actuating element is provided via which the friction element can be brought out of a locking engagement with the control element.

Abstract: A medical instrument comprises a flexible shaft which has a bendable distal end and extending along said shaft, a flexible insert which at a distal end has a tool. The flexible insert has at its proximal end a connection piece connected releasably to a grip part of a handle of the instrument. The flexible insert is secured in an axially immovable manner to a distal end of the flexible shaft and is connected to the grip part at the proximal end in an articulated manner and held in place by a catch.

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 medical-engineering coupling mechanism for connecting two medical instruments, instruments, in particular instruments for endoscopic surgery, having a coupling plug and a coupling socket for inserting the coupling plug, so that the coupling socket and the coupling plug can be secured to one another by at least one spring-loaded notching connection. To produce a medical-engineering coupling mechanism that is easy to manipulate and ensures a secure notching connection of the components that are to be connected to one another, it is proposed with the invention that the notching connection consists of at least two notching hooks that are positioned on one of the components and are in active engagement with at least one spring element configured as a spring washer, and at least one notching recess positioned on the other component for insertion of the at lest two notching hooks.
