Handheld Intraoral 3D Scanner

Abstract

The present invention provides a hand-held intraoral three-dimensional scanner, which includes a detachably connected hand-held part and an endoscope part, and the endoscope part includes a main endoscope part and one or more auxiliary endoscope parts; the main endoscope part and the auxiliary endoscope part The part is selectively connected with the hand-held part, including the first end connected with the hand-held part and the second end extending into the oral cavity; the second end is provided with a light channel opening, and a reflection device is arranged in the light channel port, and the main endoscopic part The main included angle formed by the reflecting device and the main optical axis of the projection optical path is different from the auxiliary included angle formed by the reflecting device of the auxiliary endoscope part and the main optical axis of the projected optical path. In the present invention, since the endoscopic part and the hand-held part are detachably connected, and the endoscopic part includes a plurality of endoscopic parts with different angles, different endoscopic parts can be selected to be connected with the hand-held part according to actual needs, and the The object to be scanned is scanned in all directions, and it can scan the hard-to-scan dead angle area, so as to provide accurate scanning results.

Description

technical field [0001] The invention relates to the field of three-dimensional scanners, in particular to a hand-held intraoral three-dimensional scanner. Background technique [0002] Intraoral 3D scanners generally include a handheld part and an endoscope part. When in use, the user will insert the endoscope part into the customer's oral cavity to scan the teeth, upper and lower jaws or tongue in the oral cavity. According to the scan results, the operator will formulate corresponding diagnosis and treatment plans for the customers. The accuracy of the scan results is directly related to whether the diagnosis and treatment can be performed accurately. In the current 3D scanner, the hand-held part and the endoscope part are an integrated structure, and the head angle of the endoscope part is also fixed, so it is difficult to scan the dead-angle area in the cavity, and the scanning result is not accurate enough. [0003] Therefore, there is an urgent need to provide a hand-...
