Abstract: A device (10) is used for moving a thread of a surgical sewing instrument (60). The device comprises a clamp (18) for detachably clipping said device (10) on the surgical sewing instrument (60). The device has an arm (24) having a first end connected to said clamp (18). A freely rotatable roller (50) being arranged at a second end of said arm (24), said roller (50) resting on the thread of the surgical instrument (60) having clipped on the device (10).

Abstract: The invention relates to a surgical instrument system, which comprises a hollow shaft as well as a shaft-type instrument that can be inserted into the hollow shaft. To create a surgical instrument system that consists of a hollow shaft and of a medical instrument that can be inserted into the hollow shaft and that is both simple in construction and capable of a range of uses, it is proposed according to the invention that at least one cam that reduces the inside diameter of the hollow shaft should be positioned on the interior of the hollow shaft.

Abstract: A device for securing a surgical suture to a bone comprises a first element, which can be introduced into a bone, and a second, movable element, which can be introduced into said bone in such a way that it meets said first element. A channel being formed in said bone as a result of introducing said first and said second elements into that bone. One of said two elements carries a surgical suture. A suture catcher is arranged within that element of the two elements not carrying said suture, by means of which suture catcher said suture can be taken hold of and said suture can be withdrawn via said element not carrying said suture.

Abstract: The invention relates to coupling mechanism, in particular for medical instruments, having a coupler plug and a coupler socket for inserting the coupler plug, where the coupler socket and coupler plug can be secured to one another by at least one spring-loaded catch connection, where the catch connection can be actuated by a safety mechanism and can be released by the coupler plug inserted into the coupler socket. To create a coupling mechanism that is simple to operate and ensures secure catching connection of the components and that are to be connected with one another, it is proposed with the invention that the safety mechanism should be configured as a spring-loaded catch element positioned in the coupler socket.

Abstract: The invention relates to a device for affixing to cylindrical components of medical instruments, for instance an instrumental shaft, having at least one intake part that can be mounted on the cylindrical component and can be affixed to the cylindrical component, wherein a sleeve-shaped collet chuck that essentially coaxially surrounds the cylindrical component is positioned in the intake part and whose inner diameter can be displaced between a span that can slide along the cylindrical component and a span that is in form-locking contiguity on the cylindrical component. To allow for a stationary clamping on the one hand and ensure a non-harmful clamping of the cylindrical component on the other hand, it is proposed with the invention that the inner diameter of the collet chuck can be displaced by a slider that can slide essentially diagonally to the cylindrical component and is mounted so that it can slide in the housing of the intake part.

Abstract: The invention relates to a medical-engineering coupling mechanism for connecting two medical instruments, instruments, in particular instruments for endoscopic surgery, having a coupling plug and a coupling socket for inserting the coupling plug, so that the coupling socket and the coupling plug can be secured to one another by at least one spring-loaded notching connection. To produce a medical-engineering coupling mechanism that is easy to manipulate and ensures a secure notching connection of the components that are to be connected to one another, it is proposed with the invention that the notching connection consists of at least two notching hooks that are positioned on one of the components and are in active engagement with at least one spring element configured as a spring washer, and at least one notching recess positioned on the other component for insertion of the at lest two notching hooks.
