摘要： An autoclavable handle (5) includes a handle housing (9) and with at least one switch element (11) mounted to the handle housing (9). The autoclavable handle (5) is permanently resistant to the effects of machine cleaning and of steam sterilization. The at least one switch element (11) is resiliently pressable into the handle housing (9). The switch element (11) is mounted in the handle housing (9) via at least one web (16) arranged on an underside of the switch element (11). The switch element (11) is sealed off from the handle housing (9) via a circumferential sealing element (12).

摘要： An optical instrument (1) for minimally invasive surgery includes an instrument housing (2) for receiving optical elements, wherein the instrument housing (2) is sealed in fluid tight fashion by way of at least one end window (7) on the distal side and/or proximal side. The end window (7) is arranged in a window frame (8) that surrounds the end window (7) around the entire circumference thereof. The end windows (7) is able to be attached with little stress in the associated window frame (8) based on at least two portions (12) that project radially to the inside from the window frame (8). The at least two portions (12) are formed on the inner circumferential surface of each window frame (8) facing the respective end window (7).

摘要： A coupling mechanism for mechanically connecting a first structural part and a second structural part of a medical instrument includes a first component and a second component, which are designed to be connected to each other by a bayonet connection that permits a rotation of the second component relative to the first component about a rotation axis, and a detent mechanism for alternately locking the second component in several alternative and mutually different predetermined angle positions relative to the first component.

摘要： An endoscope includes an endoscope shaft (3), which has a cylindrical shaft tube (4), and an endoscope head (2), which is arranged at a proximal end of the endoscope shaft (3). A distal end region (11) of the endoscope head (2), has a cylindrical interior (13) with a peripheral groove (15). The shaft tube (4) is inserted into the cylindrical interior (13) and folded into the peripheral groove (15). The groove (15) is not rotationally symmetrical. An endoscope head and a method for producing an endoscope are also provided.
