A positioning device for a visual navigation system of an oral implant robot

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of surgical medical instruments, and in particular relates to a positioning device for a vision navigation system of an oral implant robot. Background technique [0002] Oral implants are currently the most effective way to replace missing teeth. The technical point of dental implantology is how to accurately prepare the cavity and implant the implant according to the predetermined angle and depth at the appropriate position of the patient's jaw. With the development of computer-aided implant system (CAI), especially the application of CT technology in the field of oral implants, the problems of image distortion and overlap inherent in conventional two-dimensional perspective imaging technology have been solved, and the anatomy of the surgical area can be accurately judged from three-dimensional images. Conditions, including bone quality, bone quantity, mandibular canal and maxillary sinus position, etc., a...

Problems solved by technology

[0006] The visual navigation system of the robot is equivalent to the eyes of the robot, which can accurately locate the predetermined implant site. However, due to the narrow operating space of the oral cavity and the obstruction of the buccal soft tissue, the robot's "eyes" cannot directly locate the predetermined implant site. In order to solve this problem, it is necessary to design a positioning device, which is loaded on the dentition to be implanted and repaired, and forms a rigid connection with the marker (Marker) placed outside the mouth. The robot vision system recognizes the marker (Marker) on it. To indirectly locate the intended planting site

[0007] At present, in the clinically used oral implant surgery navigation system (such as IGI), the device loaded on the dentition in the positioning device used is made by lamination method, which needs to prepare the dentition model, lamination molding, and The steps such as grinding and polishing can only be completed, and then the self-curing resin is used to bond the external marking bracket together. Infrared markers also need a matching power supply, resulting in a complex structure
