Abstract: An assembly may include a medical device, an introducer sheath connected to the medical device, and a surgical instrument. The medical device may include a cage, a screw, a bone screw, a pedicle screw, and/or an implant. The introducer sheath may be connected to the medical device at a pre-determined breaking point. The introducer sheath may be hollow. The surgical instrument may comprise an extension. The extension may be configured to be inserted into the introducer sheath. The surgical instrument may comprise a pin. The surgical instrument may comprise a separator. The separator may be configured for breaking off the introducer sheath from the medical device at the pre-determined breaking point by rotating the extension about a longitudinal axis of the extension. A part of the medical device may be configured serve as a counter bearing to the rotation by accommodating the pin during rotation.

Abstract: A surgical instrument for separating an introducer sheath from a device connected to the introducer sheath is disclosed. In embodiments, the surgical instrument includes an extension extending in a longitudinal direction; a pin; and a separator connecting the extension and the pin.

Abstract: In a surgical instrument including a reduction instrument (2) and an adapter (3) for a pedicle screw unit (4), the pedicle screw unit (4) including a pedicle screw (5), a tulip (6) and an insertion sleeve (7), the reduction instrument (2) is to have a first coupling point (8) and the adapter (3) is to have a second coupling point (9), it being possible for the first coupling point (8) and the second coupling point (9) to be connected to one another in a force-locking and/or form-fitting manner.

Abstract: A surgical instrument includes an implant, a grip, and a pre-set breaking point connecting the implant and the grip. The implant has a joining profile.

Abstract: The invention relates to a surgical instrument comprising a bone screw having a screw head, and a shaft for rotating the bone screw in a bone, the shaft and/or head forming a single element with the bone screw and having a predetermined breaking point. A driving element is inserted into the bone screw by the shaft, said driving element screwing the screw further in or out once the shaft has broken off from the screw.

Abstract: A surgical instrument includes an implant, a grip, and a pre-set breaking point connecting the implant and the grip. The implant has a joining profile.

Abstract: A surgical instrument (1, 12) for introducing an implant, comprising a shaft (2), wherein the shaft is suitable for accommodating the implant, in particular a screw (9, 15) having a cannula (4), at the proximal end of the shaft, wherein the shaft (2) has a cannulation, and a handle (3), which is connected to the shaft (2) at a distal end of the shaft (2). The shaft (2) is provided with a slit (6).

Abstract: A surgical instrument includes an implant, which may include a cannulated pedicle screw having a screw head, a tulip connected to the screw head, an extension connected to the tulip, an ini threadedly engaged with at least one of the tulip and the extension, and/or a guide wire disposed in at least one of the extension, the tulip, and the implant.
