Publication number: 20170172690Abstract: A method for performing a stereotactic brain surgery. The method includes first interposing a left and a right anthropological baselines on a patient's face, each trago-orbital anthropological baseline connecting an orbitale point and an auricular point on a corresponding side of the patient's face. A headgear unit having a pair of temple elements and a front housing, where the front housing includes at least two cameras and a 3D compass, is then positioned on a patient's head. Each of the two cameras is adjusted such that its view field picks up one of the two trago-orbital anthropological baselines on the patient's face. These view fields of the two cameras are then used to construct a Human Skull Base Plane as a plane formed by the left and right anthropological baselines when these anthropological baselines are parallel and aligned.Type: ApplicationFiled: February 28, 2017Publication date: June 22, 2017Inventor: Albert Davydov

Publication number: 20170172691Abstract: An ophthalmic illumination apparatus can include a movable support. The apparatus can also include an optical array coupled to the movable support and positioned to interact with a light beam from a light source. The optical array can include first and second optical elements. The first optical element can be configured to reflect and transmit first associated amounts of the light beam. The second optical element can be configured to reflect and transmit second associated amounts of the light beam different than the first optical element. The apparatus can further include a drive mechanism coupled to the movable support. The drive mechanism can be configured to cause the movable support to selectively move the optical array such that the light beam is selectively incident upon one of the first optical element or the second optical element. Associated devices, systems, and methods are also provided.Type: ApplicationFiled: December 17, 2015Publication date: June 22, 2017Inventors: Vit Ulinskas, Michael J. Papac

Publication number: 20170172693Abstract: Systems, apparatuses, and methods of and for an ophthalmic illumination system are disclosed. In an exemplary implementation, an ophthalmic illumination system includes a collimator having at least one lens. The system includes a first mirror arranged to reflect light towards the collimator. The first mirror is configured for use with a first light source that emits a first light beam having a first parameter. The system includes a second mirror arranged to reflect light towards the collimator. The second mirror is configured for use with a second light source emitting a second light beam having a second parameter that is different than the first parameter. The second mirror is shaped and arranged to cause a reflected portion of the second light beam to have the first parameter. The first mirror and the first light source, and the second mirror and the second light source, are separately usable with the collimator.Type: ApplicationFiled: February 23, 2016Publication date: June 22, 2017Inventors: Ronald T.
