Estimating the term…
The invention relates to a method and device system, which are provided for removing material or tissue or for working material or tissue and which can be used in the fields of medicine and dentistry as well as for the most varied types of material working in different areas of application and model working. The invention is particularly advantageous in that an exact removal of material or a highly precise, reproducible material working can be realized within the shortest amount of time by acquiring, storing and computer processing data pertaining to position and/or orientation of the effector and their changes relative to the position of at least one reference body. In addition, commands for controlling and/or regulating are initiated in such a manner that, according to a predetermined working volume and/or material removal volume and/or material remaining volume, the effector is switched into an on/off function or, in the on function, is controlled and/or regulated with regard to its power and/or parameterization. The inventive device system is characterized in that a first marking support (6) with markings (7) is arranged on a handpiece (1) with the effector (2), in that the handpiece (1) is connected to a control unit (22), and in that a second marking support (6) with markings (7) is attached to the material object or tissue object (5).
Method for removing material or for processing material with at least one effector by employing a navigation system and by using computer technology,
Method according to one of the preceding claims, characterized in that the difference volume between the selected or actually computed fitted piece and the actual intersecting volume is computed.
Method according to one of the preceding claims, characterized in that the effector energy is switched off when the effector is located outside the geometry of the fitted piece.
Method according to one of the preceding claims, characterized in that the effector energy is switched on when the effector is located inside the geometry of the fitted piece.
Method according to one of the preceding claims, characterized in that a soft object is substantially dimensionally stabilized by a matrix which has at least one option for a defined passage or guiding of material-removing energy or a material-removing effector.
Method according to one of the preceding claims, characterized in that the difference volume geometry is used for arranging and guiding the effector.
Method according to one of the preceding claims, characterized in that based on the position and geometry of the already removed material or tissue (10) as well as on a defined position and defined geometry of an desired object shape (12), the position and geometry of the material or tissue (13) that still remains to be removed is graphically displayed on a display screen, and that the information about the position (3) of the effector (2) relative to the boundary surface between the fitted object shape and material or tissue (13) that still remains to be removed is also displayed graphically and/or acoustically and used for manually and/or kinematically arranging and guiding the effector, whereby the processed information can be outputted via an interface for controlling a placement and guidance mechanism for the effector.
System for removing material or processing material with at least one effector by employing a navigation system and by using computer technology, wherein a first marker support (6) with markers (7) is arranged on a handpiece (1) with an effector (2) and the handpiece (1) is connected with a control unit (22) and a second marker support (6) with markers (7) is secured to the material or tissue object (5).
