Abstract: A gear arrangement including two drive units (210, 220, 310, 320, 410), and two translatory transmission elements (151, 152, 251, 252, 351, 352), to each of which a rotationally movable function unit (141, 142) of a distally arranged two-part end effector (140) can be coupled. The first drive unit (210, 310, 410) has at least one proximally arranged rotation element (311, 411) or a thrust element (210) for opening or closing the end effector (140) by rotation of at least one function unit (141, 142). The second drive unit (220, 320), with which the translatory transmission elements (151, 152, 251, 252, 351, 352) are movable in opposite directions, has at least one proximally arranged rotation element (224, 320, 421) for simultaneous and unidirectional pivoting of the function units (141, 142) of the end effector (140). A surgical instrument includes the gear arrangement (200, 300, 400) in the handle (180).

Abstract: The invention concerns a handle for a video endoscope including a housing and an interface portion rotatably supported relative to the housing where the interface portion includes a first connector element at its distal end section that is connectable to a second connector element of an associated elongate shaft of the video endoscope. Thereby a detachable, rotatable electrical and/or mechanical connection between the handle and the associated shaft is achieved. The coupling includes an electrical connection assembly arranged at an exterior of the interface portion forming an electrical connection to a stationary electric component of the handle. The handle includes a mechanical rotation stop for a rotation of the interface portion relative to the housing such that a rotation range is limited and damage to the electrical connection assembly is prevented.

Abstract: The application relates to a medical instrument with a hollow shaft, with a handle at the proximal end and a tool with two jaw parts at the distal end, of which at least one jaw part is pivotable, wherein a distal end region of the shaft is configured as a deflectable, rotatable tool tip, and wherein the jaw parts are adjustable between closed and open positions, wherein rotation of the tool tip and actuation of the jaw parts take place via actuation elements coupled at the proximal end to the handle. The distal end of the shaft and the proximal end of the tool tip are arc-shaped, and roll on each other for the deflection of the tool tip, and are conveyed from the shaft into the deflectable tool tip via at least two identical joints, which are connected in series and which can transmit rotation and translatory movements.
