Abstract: A head stabilization device useable for stabilizing a head of a patient during a medical procedure includes a modular design where stabilization assemblies of various configurations are interchangeable at receiving portions along a frame. The device includes a tensioning feature positioned away from the stabilization assembly but still operable to increase or decrease an amount of force the stabilization assembly applies to the patient's head. The device includes a locking feature for a stabilization assembly having a rotatable member having one or more stabilization features connected thereto. The device includes an adjustment feature to adjust a spacing between frame members with the adjustment feature providing a continuous range of adjustment rather than finite adjustment increments.

Abstract: A joint assembly and adapter couple with a head stabilization device about one or more circumferential toothed rings of the head stabilization device. This coupling provides rotatable adjustment of the head stabilization device about two degrees of freedom including a first longitudinal axis of the head stabilization device and a second longitudinal axis of the joint assembly. The toothed rings of the head stabilization device can have multiple coupling locations to allow for a third degree of freedom for adjustment along the first longitudinal axis. A locking feature is coupled with the adapter to actuate the adapter and joint assembly for selective adjustment of the head stabilization device among the various degrees of freedom for adjustment.

Abstract: A head stabilization device includes a stabilization assembly and an applicator to control an amount of force that a stabilization feature applies to the head of the patient. The applicator includes a torque control feature that ensures a desired torque setting is not exceeding during use. The applicator can be detached from the remainder of the system such that the head stabilization device is usable without having a connected torque controlling feature or structures. The applicator in one version controls torque by adjusting a bending length of a pair of arms that extend within the applicator.

Abstract: A head fixation device includes a rocker arm assembly containing one or more stabilizing features. The rocker arm is rotatably adjustable about a longitudinal axis of the rocker arm assembly to any rotational position in a non-stepped fashion. The rocker arm assembly is removable from the head fixation device for easy of cleaning. A lever of the rocker arm assembly translates a shaft and includes eccentric features to provide a camming action for moving locking features of the rocker arm assembly to an unlocked state such that the rocker arm can be rotationally adjusted.

Abstract: A surgery system comprising at least one smart instrument, a computer system, and a sensor system adapted to wirelessly sense the position of the at least one smart instrument and to transmit position information to the computer system, wherein the sensor system includes a sensor array and the sensor array includes at least three linear CCD cameras and at least one infrared transceiver.

Abstract: Compression bone screw and screwdriver blade therefor A compression bone screw is described, with a shank having two opposite shank sections along its axial extent, a first thread being connected in a rotationally fixed manner to the shank in the region of the first shank section. The shank has at least one latching element for rotatably coupling a threaded component bearing a second thread to the second shank section. The invention furthermore relates to a screwdriver blade for the compression bone screw.

Abstract: A surgery system comprising at least one smart instrument, a computer system, and a sensor system. The sensor system is adapted to wirelessly sense the position of the at least one smart instrument and to transmit position information to the computer system.

Abstract: The present invention is a system for installing bioabsorbable plates for general bone repair, as for example, facial or cranial osteosynthesis. The present invention includes an improved plate and fastener system which reduces if not eliminates stresses within the plate. It also includes an improved fastener container and driver for handling and installing fasteners. The system employs a unique water bath for heating the bioabsorbable plate so they can be deformed to the contours of the bone being repaired. Additionally, there is a hand tool for localized heating and deformation of the plate when positioned against the bone to further ensure conformity with the bone structure. These and other features are contained within a kit which is easily sterilized.

Abstract: A lattice for the fixation of bone parts or for the bridging of bone defects, particularly in the region of the skull and jaw, is made of biocompatible material with a reticular structure and with recesses for receiving bone screws, with which the lattice can be secured on the bone. The lattice does not have circular rings for receiving bone screws, but instead each lattice recess (32) can be used for receiving a bone screw. The bridges form meandering, continuous, regular bridge rows along the main axes of the lattice.
