Abstract: A quick stop drilling tool for use with a medical or dental treatment device includes a drilling tool having a body extending between a connection end and a working end and having a longitudinal extension along a longitudinal axis of the drilling tool. The drilling tool has a hollow outer shell in which a probe is held that can be moved along the longitudinal axis so that a part of the probe can be moved out of the shell through an opening. The probe is designed as an elongated pin, and its first end facing the connection end is held in the interior of the hollow outer shell. An electromagnetic sensor for detecting relative movement between the shell and the probe is arranged along the longitudinal extension of the body. The drilling tool has a channel for a treatment fluid extending along the longitudinal axis.

Abstract: The invention relates to a bone screw set for fixing two bone fragments, especially for treating a scaphoid bone fracture or a scaphoid bone pseudoarthrosis, comprising a first bone screw (1) and at least one second bone screw (2). The first bone screw (1) is preferably embodied as a compression screw, and the first and second bone screws (1, 2) comprise interacting engagement means for fixing the second bone screw (2) in a position, in relation to the first bone screw (1), wherein at least part of the second bone screw protrudes from the cross-section of the first bone screw (1).

Abstract: The invention relates to a bone screw set for fixing two bone fragments, especially for treating a scaphoid bone fracture or a scaphoid bone pesudoarthrosis, comprising a first bone screw (1) and at least one second bone screw (2). The first bone screw (1) is preferably embodied as a compression screw, and the first and second bone screws (1, 2) comprise interacting engagement means for fixing the second bone screw (2) in a position, in relation to the first bone screw (1), wherein at least part of the second bone screw protrudes from the cross-section of the first bone screw (1).

Abstract: The invention relates to a method for carrying out a percrestale sinus lift, wherein a bore channel is created with the aid of a boring, milling and/or hammering method, the Schneider membrane is lifted from the jaw bone using a flowable medium that is supplied via the opened bore channel, bone replacement material is introduced, a supply line is introduced into the bore channel prior to introducing the flowable liquid and is sealingly fixed in a detachable manner to the bore channel or onto the edge thereof and the flowable medium in introduced through the supply line. The invention also relates to a surgical instrument (1) for introducing a flowable medium for lifting the Schneider membrane from the jaw bone whilst carrying out a percrestale sinus lift.

Abstract: An implant for fastening ligaments or tendons to a bone or bone replacement, generally referred to as a bone member. The implant has a housing, a device for fixing or attaching a ligament or tendon, and a device for being fastened to the bone member. The fixing device can be displaced relative to the fastening device. At least one motor is provided for displacing the fixing device relative to the fastening device. The motor is connected to a receiver for telemetrically triggering the motor. The implant allows the tension of the ligament or tendon and the position of the attachment of the ligament or the tendon to be post-operatively adjusted in an optimal fashion.

Abstract: A drainage implant for draining chamber water from the eye, comprising a tube-shaped part (1) which has at least one lumen, whose open distal end (3) can be introduced into an episcleral vein and whose open proximal end (2) can be introduced into the front eye chamber for draining the chamber. The proximal and center areas of the tube are covered with silicon. Said covering is embodied in the center area in the form of a plate (6) with eyelets (6) in order to stabilize and fix the implant by means of sutures on the sclera. The implant contains a guide wire (8) inside the tube (1), the front of said guide wire being acutely sharpened. The guide wire is used to puncture the vein and also stabilizes the very thin tube (1) for implantation.

Abstract: An instrument for the surgical closure of a trocar puncture through a posterior fascia introduced during a laparoscopic operation comprises a tube (1) with a forward insertion end (2) and a rearward end (3), in whose shell wall (5) opposing window openings (7) are formed, in which terminates at its margins remote from the insertion end (2) of the tube (1) at least one bore (8) extending in the shell wall (5) in the longitudinal direction of the tube (1), hollow needles (10), each disposed in one of the bores (8) and displaceable between a retracted position, in which they clear the particular window opening (7), and an end position, in which they cross the window opening (7), and each having an inner channel (17), wherein each of the inner channels (17) of the hollow needles (10) forms a section of a guide channel for guiding through a suture thread (36), and this guide channel further includes at least one curved connecting section (18), which connects the front ends of the inner channels (17) of two holl
