Abstract: An impactor and methods of operation of an impactor. The impactor includes an electromagnetic component that has a stationary electromagnetic housing and a moving magnet actuator, a striker, and one or more strike plates. The striker is coupled to an object. The stationary electromagnetic housing includes a coil that receives an electric current. The moving magnet actuator includes one or more magnets. The magnets generate a high potential magnetic field that interacts with the electric current applied to the coil disposed within the stationary electromagnetic housing and trigger translation movement of the moving magnet actuator. The electromagnetic field, generated as a result of application of the electric current to the coil, forces the moving magnet actuator to translate. Translation of the moving magnet actuator causes the moving magnet actuator to strike at least one of the strike plates to thereby translate the striker.

Abstract: A bone cutting device, such as a burr or saw blade, is irrigated to cool not only the bone cutting device itself, but also the bone of the subject on which a bone resection procedure is being performed. The bone cutting device can have one or more (e.g., a plurality of) internal flow channels that eject a cooling medium (e.g., water or an inert gas) from the bone cutting device. This emission of the cooling medium can not only flush bone chips from the resection site, thereby reducing frictional heating of the bone cutting device, but can also provide internal cooling to the bone cutting device while flowing through the one or more internal flow channels and also can cool the surface of the bone via conductive heat transfer (e.g., by the flow stream of the cooling medium impinging on the bone surface).

The outer sleeve includes at least one electrode for electrosurgically treating tissue. The reusable handle includes at least one control switch for controlling a parameter associated with the rotation of the inner shaft. The blade also may include a switch assembly in electrical communication with the at least one electrode, the switch assembly including attachment means for selective attachment of the switch assembly to the reusable handle.

Abstract: A method of generating a custom three-dimensional (3D) model of a patient bone from one or more 2D images is disclosed. The method includes obtaining a 2D image of a bone, optionally of a joint, and identifying a 3D bone template for a candidate or representative bone from a pre-aligned library of representative bones. The method further includes repositioning one or more views of the 3D model or 2D images (e.g., with respect to rotation angle or caudal angle). In an iterative process, another 3D bone model for another candidate bone can be identified based on the repositioning until an accuracy threshold is satisfied. When the accuracy threshold is satisfied, surface region(s) of the current 3D bone model can then be modified to generate the resulting 3D model for the patient bone. The process can then be repeated for other bone(s) associated with the joint of the patient.

Abstract: Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a driving circuit that supplies a driving signal to a negative pressure source to cause the negative pressure source to provide negative pressure via a fluid flow path to a wound dressing. The apparatus furthers include a controller that adjusts a frequency of the driving signal supplied by the driving circuit according to a comparison of a previous magnitude and a subsequent magnitude of the driving signal while the negative pressure source provides negative pressure. The transfer of power to the negative pressure source can thereby be tuned to maximize an amount of power transferred to the negative pressure source.
