A universal drill guide system includes a universal drill guide, interchangeable drill tubes, and interchangeable drill bits. Each interchangeable drill tube corresponds to one of the interchangeable drill bits, and can be detachably coupled to the universal drill guide. A cannulated drill with K-wire retention features a drill bit with a retention mechanism that prevents axial advancement of a K-wire during drilling. A drill removal tool includes a drill remover that can be placed around a drill bit to remove it from bone after a hole is drilled, while leaving a K-wire in place in the bone. A bone screw driver with K-wire retention includes a shaft that can be passed over a K-wire, a distal end for attachment to a cannulated bone screw, and a K-wire retention module for preventing advancement of the K-wire as the screw driver drives the cannulated bone screw into bone.

Surgical instrumentation for fixation of cervical spine

The invention relates to a spinal implant composed of a plurality of parallel plates. The deliberate introduction of contours in the plates allows for the creation of biomechanically advantageous functions and adjustment options. The elasticity of the anchoring elements enables the disclosed implant to be adjusted to the osseous endplates, resulting in uniform force distribution and thus prevention of the risk of compaction or endplate compression fracture. The plate structure allows for the use of production methods in which hook-like undercut contours can be created, thus enabling the implant to be superbly anchored in the bone without causing damage thereto. Furthermore, the plates can be interconnected by an actuator in such a way that the height and/or the angular position can be adjusted. The vertical adjustment can vary along the length of the implant such that the segment can also be angularly adjusted.

Intervertebral medical implant

The invention relates to an implant in the form of a bone-connecting device with an implant carrier, having at least two structure carriers for stimulating bone growth, the structure carriers can move relative to one another so that, due to a loading of the implant, a relative movement of the structure carriers occurs, the structure carriers furthermore contain structure elements that are arranged so that they define a plurality of partially open intermediate spaces, wherein a volume defined by these intermediate spaces and an immediate environment is deformed by the implant load, and a strain in the intermediate spaces and its immediate environment resulting from the deformation lies in the physiological range for bone growth.
