Publication number: 20190321126Abstract: Systems, methods and software are provided for aiding in positioning of a camera relative to objects in a surgical environment. The camera has a 3D field of view and senses positions of the objects in the field of view. A controller is coupled to the camera and defines a first zone and a second zone within the field of view. Each zone defines a range of acceptable positions for one of the objects relative to a position of the camera. The controller receives the position of the objects. A graphical user interface displays image representations of: the field of view, the first zone relative to the field of view, the second zone relative to the field of view, the position of one object relative to the first zone, and the position of another object relative to the second zone.Type: ApplicationFiled: April 22, 2019Publication date: October 24, 2019Applicant: MAKO Surgical Corp.Inventors: Jason Karl Otto, Matthew Thompson, Mark Ellsworth Nadzadi, Roberto Montane, Jonathan Morgan, Bojan Gospavic

Patent number: 10410837Abstract: A plasma-treatment instrument for treating a surface with a dielectric-barrier plasma field generated between an electrode and the surface has a high a.c. voltage supplied to the electrode by a controller. The electrode forms with a dielectric surrounding the electrode a cylindrical roller that is rotatably supported in a grip housing. The plasma-treatment instrument has a shell surface and is capable of being rolled along the surface. The plasma-treatment allows an efficient and safe treatment of the surface by virtue of the fact that the electrode includes at least two partial electrodes arranged alongside one another at equal intervals from the shell surface and which are insulated from one another by the dielectric. The at least two partial electrodes are connected to different terminals of a source of high a.c. voltage.Type: GrantFiled: December 10, 2018Date of Patent: September 10, 2019Assignee: CINOGY GMBHInventors: Melanie Ricke, Dirk Wandke, Leonhard Trutwig, Karl-Otto Storck, Mirko Hahnl
