Abstract: A method for manufacturing a micromechanical component having a disengaged pressure sensor device includes: configuring an electrically conductive sacrificial element in or on a first outer surface of a first substrate; applying a second substrate on or upon the outer surface of the first substrate over the sacrificial element; configuring a pressure sensor device by anodic etching of the second substrate; configuring in the second substrate at least one trench that extends to the sacrificial element; and at least partly removing the sacrificial element in order to disengage the pressure sensor device.

Abstract: A shaft for a micro-invasive surgical instrument includes a shaft tube with a proximal end portion and a distal end portion, a coupling device for detachable mechanical coupling of the shaft with a tool, and a rotation bearing, which mechanically connects the coupling device with the distal end portion of the shaft tube. The rotation bearing is configured in order to allow rotation of the coupling device with respect to the shaft tube about the longitudinal axis of the shaft on the distal end portion of the shaft.

Abstract: An articulation device for a medical instrument includes a coupling for releasable mechanical connection of the articulation device to a tool or to the distal end of a shaft, a locking device on the coupling for locking the mechanical connection, and an articulation, which enables the coupling to be angled relative to an end of the articulation device remote from the coupling. The locking device is designed such that the mechanical connection is locked in a predetermined working angular position of the articulation and is releasable in a predetermined release angular position of the articulation.

Abstract: A medical instrument according to the invention has an elongate shank, and a tool which is arranged on a distal end portion of the shank and which comprises two tool elements interacting with each other, of which at least one tool element is movable by a longitudinally displaceable first transmission element. A distal end portion of the first transmission element has a surface inclined with respect to a direction of displacement, and the distal end portion of the shank, or an element connected non-displaceably thereto, has a mating surface which is inclined with respect to the direction of displacement and which, with the inclined surface, forms an interspace dependent on a displacement of the distal end portion of the first transmission element.

Abstract: A tool for a dismantlable medical instrument includes a first component, which surrounds a cavity for receiving a distal end of a shank, and a second component with a catch, which protrudes into the cavity surrounded by the first component to form a bayonet connection with a distal end of a shank protruding into the cavity, by engagement of the catch in a slit or a groove at the distal end of the shank. The first component has a recess into which the second component is fitted.

Abstract: A transmission adapter for a medical instrument with a shaft, a transmission device movable in the shaft, and a manipulating device with a first part, which can be coupled mechanically rigidly to a proximal end of the shaft, and a second part, which is movable relative to the first part, includes a first coupling element for releasable mechanical coupling to the second part of the manipulating device, and a second coupling element for releasable mechanical coupling to a proximal end of the transmission device.

Abstract: A medical instrument includes an outer shaft, a manipulation device at the proximal end of the outer shaft, a tool at the distal end of the outer shaft, with a first effecting device for a first function and a second effecting device for a second function, a first transmission device in the outer shaft for transmitting at least either a force or a torque for controlling the first effecting device, and a second transmission device in the outer shaft for transmitting at least either a force or a torque for controlling the second effecting device. The outer shaft is at least either curved or able to be curved or has a pivot joint. The first transmission device and the second transmission device are each designed to be flexible at least in sections.
