Document Type and Number:
WIPO Patent Application WO/2024/066367
Kind Code:
A1
Abstract:
Provided is an apex radicis dentis positioning and measuring device, which belongs to the technical field of dental auxiliary tools. The device comprises a host (11), a display screen (15) being arranged on the host (11); and a base assembly (20) comprising a housing (21), a placement block (22) provided on the housing (21), and a distance measurement mechanism (23) provided corresponding to the placement block (22). The distance measurement mechanism (23) comprises a sliding member (23a) set parallel to the placement block (22), a driving member (23b) for driving the movement of the sliding member (23a), and a marking member (23c) fixed on the sliding member (23a). The distance measurement mechanism also comprises a PCB circuit board (23d) set opposite to the sliding member (23a), with a distance measurement unit (23e) connected to the sliding member (23a) and/or the PCB circuit board (23d). By means of the method where a file needle remains stationary while the distance measurement mechanism (23) moves and the movement distance of the making member (23c) is recognized by means of an electronic control distance measurement unit (23e) and displayed on the display screen (15), the problems of poor precision and large errors caused by manual holding in existing rulers are resolved, thereby improving the precision and efficiency of surgical treatment.
