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： One embodiment relates to a medical instrument (1) with a hollow shaft (2), an actuating unit (4) arranged at the proximal end (3) of the shaft (2) and an instrument tip (6) with an instrument (7) arranged at the distal end (5) of the shaft (2), wherein the instrument (7) can be actuated via an actuating element (8) which is mounted in the shaft (2) in an axially displaceable manner, and wherein the actuating element (8) is operatively connected to the actuating unit (4) on the proximal side, and wherein the instrument tip (6) can be pivoted relative to the longitudinal axis (10) of the shaft (2) via a joint mechanism (9). According to one embodiment, the instrument tip (6) can be rotated endlessly, wherein a fixing device is provided on the instrument tip (6) with which the loose end (17, 23) of a sewing material (18, 24) can be fixed on the instrument tip (6).

摘要： An endoscopic instrument is disclosed that includes an elongate shaft and an instrument insert releasably connected to a distal end portion of the shaft, the distal end portion of the shaft being in the form of a sleeve and a proximal end region of a base of the instrument insert being in the form of a coupling shaft, or the distal end portion of the shaft being in the form of a coupling shaft and a proximal end region of a base of the instrument insert being in the form of a sleeve, with the coupling shaft being releasably held in the sleeve and the sleeve and/or the coupling shaft at least in portions having a cross-sectional profile which is reversibly changeable for detaching the coupling shaft from the sleeve. The invention also relates to a shaft for an endoscopic instrument, and to an instrument insert for an endoscopic instrument.

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.
