3D scanner with steam autoclavable tip containing a heated optical element

摘要

A 3D scanner for recording topographic characteristics of a surface of at least part of a body orifice, where the 3D scanner includes a main body having a mounting portion; a tip which can be mounted onto and un-mounted from the mounting portion, where the tip is configured for being brought into proximity of the body orifice surface when recording the topographic characteristics such that at least one optical element of the tip is at least partly exposed to the environment in the body orifice during the recording; and a heater for heating the optical element, where the heat is provided by way of thermal conduction; where the tip can be sterilized in a steam autoclave when un-mounted from the main body of the 3D scanner such that it subsequently can be reused.

主权项

1. A tip for a 3D scanner for recording topographic characteristics of a surface of at least part of an orifice of a patient, where the tip comprises:
a framework comprising a first opening configured for engaging a mounting portion of a main body of a 3D scanner, and a second opening configured for allowing light received from a surface to enter the tip; an optical element which at least partly is exposed to the environment in the orifice during said recording; and means for providing heat to the optical element, wherein the means for providing heat to the optical element comprises a heat conducting element arranged for conducting heat to said optical element, and the heat conducting element is arranged such that a thermal connection can be made between the heat conducting element and an electrical heater element of the mounting portion of the main body; where the tip is configured to be sterilized when un-mounted from a mounting portion of the 3D scanner such that the tip subsequently can be reused.
