The invention relates to a medical instrument with an elongated element and an end effector (200) arrangeable at one end of the elongated element. The end effector (200) is operable by means of a hydraulic actuating mechanism (100), and the hydraulic actuating mechanism (100) has a cylinder body (110) with at least one, preferably two, three, four or five, overflow channels (112a, 112b, 112c) for a hydraulic fluid, the overflow channels being connected via at least one bore to the interior of the cylinder body (110). A piston (140) movable along the longitudinal axis (A) of the cylinder body (110) is provided in the cylinder body (110). The piston (140) subdivides the interior of the cylinder body (110) into a first cylinder chamber and a second cylinder chamber and is connected via a piston rod (141) to the end effector (200). At least one connection (123) for introducing hydraulic fluid into the first cylinder chamber and at least one further connectinion (124a, 124b, 124c, 124d, 124e), connected to at least one first overflow channel (112a, 112b, 112c) of the cylinder body (110) are provided, and at least one passage (130) for a surgical or optical instrument, the longitudinal axis of which substantially coincides with the longitudinal axis (A) of the cylindrical body (110), is arranged in the interior (113) of the cylinder body (110).
A medical instrument with an elongated element and an end effector arrangeable at one end of the elongated element, wherein the end effector is operable by means of a hydraulic actuating mechanism, the hydraulic actuating mechanism has a cylinder body with at least one, preferably two, three, four or five overflow channels for a hydraulic fluid, which are connected via at least one bore to the interior of the cylinder body, a piston arranged in the cylinder body and movable along the longitudinal axis of the cylinder body is provided, wherein the piston subdivides the interior of the cylinder body into a first cylinder chamber and a second cylinder chamber and is connected via a piston rod to the end effector, and at least one connection for introducing hydraulic fluid into the first cylinder chamber and at least one further connection which is connected to at least one overflow channel of the cylinder body are provided, wherein at least one passage for a surgical and/or optical and/or therapeutic instrument is arranged in the interior of the cylinder body.
