摘要： The invention relates to a medical instrument having an elongated shaft, a movable tool at a distal end of the shaft, a handle with a movable grip part at a proximal end of the shaft, and a force transmission element which can be moved in the longitudinal direction of the instrument and is operatively connected to the movable grip part and to the tool such that an actuation of the movable grip part is converted into a movement of the tool. The instrument has a spring assembly that is arranged on the handle and has at least one leg spring, which has at least one winding and two legs, and a pin, wherein the at least one winding extends about the pin. When the movable grip part is actuated, a force is applied to at least one of the legs of the leg spring, said force reducing the friction between the winding and the pin such that the leg spring can be rotated about the pin and the force transmission element and the tool can be moved. When a force is transmitted from the tool to the force transmission element in the longitudinal direction thereof, the leg spring cannot be rotated about the pin such that the force transmission element and the tool cannot be moved.

摘要： A manipulation device (14) for a microinvasive medical instrument (10) comprises a first grip member (22) and a second grip member (40), that are movable relative to each other, an irrigation port (90) for receiving an irrigation liquid for cleaning the manipulation device (14) between two uses, and an irrigation channel (92, 94, 96, 98) that connects the irrigation port (90) to one or more outlets (93, 95, 33, 65). The irrigation channel (92, 94, 96, 98) is arranged in the first grip member (22).

摘要： A dilation device including a dilation instrument which includes a distal radially expandable section which is coupled via an elongate shank to a handling section, and an expandable covering with a closed distal end and an open proximal end, for the expansion section of the dilation instrument. The covering has a shank section extending along the shank of the dilation instrument. The open proximal end of the covering is detachably coupled to the distal end of the handling section of the dilation instrument. Furthermore, the covering is disclosed per se, which consists of a mesh material and has a shank section, which is connected to a coupling sleeve at the open proximal end.
