Abstract: A shaft for a medical instrument includes a controlled curvable portion or a hinge, an uncontrolled flexible portion, and a shaft coupling device for the releasable mechanical connection of the shaft to a maneuvering device.

Abstract: A medical instrument is provides that includes a handle, a shaft, and a tool insert. The tool insert is attachable to the shaft by a threaded connection which engages a slot connection and to the handle and by a retaining member for actuation of the tool.

Abstract: An endoscopic instrument system for performing endoscopic interventions via a natural access path, including a flexible endoscope with an endoscope handle and an elongate endoscope shaft introducible into a hollow space in a body, wherein the endoscope shaft includes a steerable end section and at least one instrument channel, and also includes an endoscopic instrument with a handle, an elongate instrument shaft and a tool which can be actuated by a pull and/or push element arranged within the instrument shaft and connected to the handle and to the tool, wherein the endoscopic instrument can be introduced into the instrument channel for conducting manipulations in the hollow space in the body, and wherein the instrument shaft includes a continuous flexible tube that is connected, such that it is rotationally fixed, to the handle and to the tool with respect to a longitudinal direction of the tube.

Abstract: A medical instrument includes 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 includes a shaft which is connected at the proximal end to a handle, and it also includes 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: A medical-engineering coupling mechanism for connecting two medical instruments 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 least two notching hooks.

Abstract: A shank for a medical instrument includes a controlled curvable portion or a hinge, an uncontrolled flexible portion, and a shank coupling device for the releasable mechanical connection of the shank to a maneuvering device.
