Abstract: A surgical instrument with a handle, a shaft extending from the handle into a distal direction, and an effector, preferably a (medical/surgical) forceps or a scissor, at a distal end of the shaft. The handle comprises a plurality of manual actuating members being adapted to manipulate the effector for rotating, tilting and open-closing movements. The plurality of manual actuating members comprise a first actuating member being rotatable around a rotational axis, which is a longitudinal axis of the shaft or that is parallel offset to the longitudinal axis, and a second actuating member being rotatable around a rotational axis, which is identical to the rotational axis of the first actuating member or is parallel offset thereto and being movable (axially) along the longitudinal axis of the shaft.

Abstract: A tissue clip application fitting or retrofitting set comprising a cap attachment configured to be mounted on the distal end portion of a shaft-type medical endoscope. The cap attachment has a proximal mounting or placement portion and a distal tissue clip holding portion, in the region of which a cavity open at least in the distal direction is formed inside a radially outward-pointing peripheral surface. A tissue clip is supported on the peripheral surface, and can be displaced in the distal direction by a pull-off device in the form of a pull-off ring mounted on the radial outer peripheral surface of the tissue clip holding portion so that it can axially slide and move the tissue clip. The pull-off ring is operated by a cable pull that is in direct contact with the pull-off ring for the transmission of sliding force in at least two coupling or engagement points.

Abstract: A surgical method for operating a trocar defining an access port for a surgical instrument, using a holding arm and a number of drives. The method includes: inserting the trocar through an abdominal wall of the patient body; operating at least one drive to move the surgical instrument in the patient body; operating at least one drives to actuate an effector; and moving the holding arm to generate a pivoting movement of the trocar and surgical instrument about a pivot point defined by the abdominal wall of the patient body. The trocar is freely pivotable relative to the holding device, and the pivoting movement is caused by contact between the trocar and the abdominal wall of the patient body or an elastic membrane located on the abdominal wall of the patient body.

Abstract: A device for robot-assisted surgery with at least one coupling unit (100) of a manipulator arm (16) comprising a first transmitting means (102). A sterile cover (38) comprising a sterile lock (200) serves to shield the manipulator arm (16) from a sterile area (39). The sterile lock (200) is connectable both to the coupling unit (100) and to the sterile unit (400). The sterile lock (200) has at least one lock flap (208, 210) which in a closed state shields the first transmitting means (102) in a sterile manner. The sterile unit (400) comprising a second transmitting means (406) has sterile flaps (402, 404) which in a closed state shield the second transmitting means (406) in a sterile manner. When connecting the sterile unit (400) to the sterile lock (200) the lock flap (208, 210) and the sterile flap (402, 404) are opened so that a direct transmission between the first transmitting means (102) and the second transmitting means (406) is possible.

Abstract: Particularly in hospitals, care homes or similar institutions, it is necessary to have a safely handled and reliable method for the emptying and cleaning of excretion containers, for example urine bottles or bedpans. A method and a system (110) are therefore proposed, by means of which such articles to be rinsed (112) can be treated. In this case, first, in an emptying step (210), the articles to be rinsed (112) are emptied and are rinsed out with a rinsing-out liquid. Subsequently, in a circulation step (212), the articles to be rinsed (112) are washed in circulation. Finally, a rinsing-clear step (214) is carried out, in which the articles to be rinsed (112) are rinsed with a rinsing-clear liquid. Then, in an optional disinfection step (216), preferably a chemical disinfection step (216), the articles to be rinsed (112) are disinfected, and, in an optional drying step (218), the articles to be rinsed (112) are dried by being blown off with heated air.
