Abstract: The invention relates to a two-part hinge device for a door or a window, comprising a first housing part (20) and a second housing part (30), which in the assembled state form a door hinge housing (19), and a rod (15) which extends in the first housing part (20) and second housing part (30) along the axial direction (60) thereof, wherein the rod (15) has at least three successive—a first, a second and a third-rod sections (16, 17, 18). The first rod section (16) is supported in the first housing part (20) by a clamping element (50), and the third rod section (18) supports the second housing part (30). In the region of the second rod section (17), the rod (15) is adjustable relative to the first housing part (20) in two directions at an angle to each other and independently of each other, and the two directions at an angle to each other are arranged transversely to the axial direction (60) of the rod (15).

Abstract: An adaptable working-channel apparatus comprising: at an external working channel attached at its proximal end to a first mounting coupling; a handle-mounting sleeve for surrounding an endoscope shaft or handle, and having on its radially outer peripheral side at least one second mounting coupling for releasable mounting engagement with the first mounting coupling. The first mounting coupling comprises two spring-loaded clamping branches that are hinged together like a clothes pin and each form a clamping portion and an actuation portion. The second mounting coupling has a mounting rail extending in the longitudinal direction of the handle-mounting sleeve and has or forms at least one undercut that can be interlockingly clasped by the clamping branches of the first mounting coupling. Also provided is a distal tissue-clip application adapter that is connectable to the adaptable working-channel apparatus; and a surgical equipping system, having the working-channel apparatus and tissue-clip application adapter.

Abstract: A treatment instrument which can be coupled to a distal end of an endoscope and has a hollow body and a gripping element. The gripping element can be operated via an actuation mechanism situated inside the hollow body. The gripping element is configured in the form of a cap with which a distal end of the hollow body can be closed. The invention also relates to an endoscope having a distal end which is coupled or can be coupled to a treatment instrument according to the invention.
