Abstract: A screwdriver serves for handling a screw in the body of a person or an animal. The screwdriver has a handle, and a stem permanently connected to said handle. An outer tube surrounds the stem. A locking mechanism has a locking element engaging into a locking point in at least three different axial displacement positions of said outer tube. The locking element is prevented from moving further in an axial direction at a locking position by a barrier, which barrier can be overcome only by rotating said outer tube and said stem relative to one another about a longitudinal axis.

Abstract: A medical instrument, especially a uterus manipulator, comprises a shaft, an actuator movable relative to said shaft in order to move a tool and a locking device to lock the actuator relative to the shaft. It is now proposed that the locking device comprises a clamping element which is slidably arranged therein.

Abstract: A device for fixing and tensioning at least one pulling thread for applying a neovagina comprises a base body on which at least one fixing element is arranged for fixing the at least one pulling thread with tensioning. The fixing element is able to turn about an axis of rotation in order to tension the at least one pulling thread, and a blocking device is provided for the fixing element, by means of which blocking device the fixing element can be blocked at least in a direction of rotation opposite to the direction of rotation for tensioning the at least one pulling thread.

Abstract: The invention relates to a surgical instrument system encompassing a morcellator with a hollow shaft on whose distal end a cutting blade is configured, as well as a gripping instrument with a shaft on whose distal end a tool consisting of at least two jaw members and on whose proximal end a handle consisting of at least two gripping members is configured to activate the tool, in such a way that the gripping instrument can be inserted into the hollow shaft of the morcellator so that it can slide in the longitudinal direction of the morcellator shaft. To ensure versatile application along with simple structure, it is proposed with the invention that the morcellator with the insertable gripping instrument can be inserted into a hollow shaft of an additional medical instrument, in particular a resectoscope, and that an additional irrigation and/or suction canal is configured between the shaft of the morcellator and the inside of the hollow shaft of the additional medical instrument.

Abstract: The invention relates to a medical instrument with a handle on which at least one gripping part, in particular a finger ring, is secured by a connecting clamp in a removable manner and is mounted in rotatable fashion on one handle part, and the connecting clamp consists of a shaft configured on one of the components that are to be connected to one another and of a sheath configured on the other component and where the outer diameter of the shaft, forming an undercut in the area of the free end of the shaft, exceeds the core diameter of the shaft and the inner diameter of the sheath correspondingly has an area forming an undercut and serving to receive the free end of the shaft, with a larger inner diameter, and an area extending in the direction of the sheath opening with a lesser inner diameter.

Abstract: An endoscopic instrument is provided comprising a shaft having an endoscope optical system arranged therein, which has a distal front face. The instrument also comprises a working element arranged in the shaft. The shaft provides for the supply of an irrigation fluid. Flow-influencing means are provided, such that the irrigation fluid reaches in front of the front face of the endoscope optical system and can eliminate contaminations, which obstruct the view through the endoscope optics.

Abstract: The invention relates to a medical instrument with a handle (3) on which at least one gripping part (7), in particular a finger ring, is secured by a connecting clamp in a removable manner and is mounted in rotatable fashion on one handle part (4, 5), and the connecting clamp consists of a shaft (10) configured on one of the components (4, 5, 7) that are to be connected to one another and of a sheath (11) configured on the other component (7, 4, 5) and where the outer diameter of the shaft (10), forming an undercut (13) in the area of the free end of the shaft (10), exceeds the core diameter of the shaft (10) and the inner diameter of the sheath correspondingly has an area forming an undercut (14) and serving to receive the free end of the shaft (10), with a larger inner diameter, and an area (15) extending in the direction of the sheath opening with a lesser inner diameter.

Abstract: The invention relates to a medical instrument for removing tissue comprising a tool at its distal end which can be supplied with high frequency power. The instrument includes an HF power terminal and an HF power supply line extending frown a proximal end region of the instrument to its distal end. In the present instrument, the HF power supply is configured as a drive shaft for rotary drive of the tool. Furthermore, contact means are provided electrically connected to the HF power terminal, which electrically contact the drive shaft.
