The invention discloses a positioning device of an oral implanting
robot vision
navigation system. The positioning device comprises a tray, a marking plate, a connecting rod, an opening
retainer, an
endoscope support and retaining screws. A tray
handle of the tray is fixed through one retaining screw after being matched with a tray inserting portion of the connecting rod in position through a connecting rod inserting hole. A retaining screw hole B in the marking plate is fixed through one retaining screw after being matched with a retaining screw hole C of a connecting portion A of the connecting rod in position. The opening
retainer is meshed with the interior of an opening
retainer clamping groove in the tray through a toothed opening in the lower portion of the opening retainer. The
endoscope support is fixed through one retaining screw after being matched with a retaining screw hole D in the
endoscope support in position through an endoscope support inserting hole. According to the scheme, the operation steps are simplified, after the appropriate tray is selected according to clinic requirements, the tray can be stably fixed to a
dentition by the adoption of a
silicone rubber impression film preparation method, the tedious steps needed by manufacturing a device loaded on the
dentition through a membrane pressing method are omitted, and preoperative preparation time and the
patient treatment frequency are reduced.
