Abstract: A medical sliding shaft instrument includes a tool element carrier, a tubular sliding shaft surrounding the tool element carrier and defining a sliding direction, and an actuating device for moving the sliding shaft relative to the tool element carrier in the distal direction. At least one tool element is arranged or movably mounted on the distal end of the tool element carrier. The at least one tool element is arranged or formed so as to cooperate with a distal end region of the sliding shaft in such a way that the at least one tool element is moved as a result of a movement of the sliding shaft in the distal direction. The sliding shaft instrument further comprises a locking device for blocking a movement of the sliding shaft relative to the tool element carrier in at least one advancing position.

Abstract: The present invention relates to novel pyridazin-3-yl phenol compounds of Formula (I): wherein R1, R2, R3, R4, R5 and Z are defined herein, which inhibit NOD-like receptor protein 3 (NLRP3) inflammasome activity. The invention further relates to the processes for their preparation, pharmaceutical compositions and medicaments containing them, and their use in the treatment of diseases and disorders mediated by NLRP3.

Abstract: A joining method for a medical device, in particular a surgical instrument or implant, with a shaft and an attachment to be secured on the shaft, the method having the following steps: heating the attachment or cooling the shaft, such that an internal diameter of an opening of the heated attachment is greater than an external diameter of the shaft, then placing the shaft into the opening of the attachment, and then cooling the attachment, so as to shrink the attachment onto the shaft in a manner substantially free of gaps, or heating the shaft, such that the shaft and the opening are connected by an interference fit. A corresponding medical device is produced by the joining method.

Abstract: An endoscope having an endoscope shaft and a main body, which is connected to the endoscope shaft and on which a first dial that has a first contact surface is mounted in a rotatable manner, is provided. The main body has a second contact surface against which the first contact surface bears. The contact surfaces move against one another when the first dial is rotated. A first setting unit is provided, using which a pressure force with which the first contact surface is pressed against the second contact surface is settable in order to set a minimum torque that is necessary in order to rotate the first dial.

Abstract: An electric drive provides transmission oil cooling. An oil circuit supplies the transmission with oil. A cooling circuit cools a supply device and/or an electric motor with a coolant.
