Abstract
A probe for measuring distances of clincal interest in a patient undergoing dental treatment has an end which is placed adjacent a first point and a tip which is extendable to a second point. A measurement apparatus in the housing, provides an output signal representative of the distance between the two points. An analyzer responsive to the output signal determines the distance. A friction mechanism assures that no more than a predetermined amount offorce is applied to the probe, making repetitive measurements accurate and avoiding damage to tissues. A microcomputer and printer analyze the data and present the data in a useful format. The tip of the probe is provided with storage apertures for use in delivering medication via the probe member. The probe is provided with an optical fibre cable and an optical encoder which is supported for rotary motion within the housing for eliminating cable twist evolved during manipulation. The tip of the probe is replaceable and provided with a frangible support which prevents reuse.
