Measuring probe. |
摘要 |
<p>A probe (20) for measuring distances of clinical interest in a patent undergoing dental treatment comprises a probe member (78; 306) which is extendable from a first to a second point. A measurement (136; 182) apparatus in a housing (68; 300) provides an output signal representative of the distance between the two points. An analyzer (32, 48) responsive to the output signal determines the distances. A friction mechanism (69, 94, 96) assures that a predetermined amount of force is applied to the probe, making repetitive measurements accurate and avoiding damage to tissues. A microcomputer (32) and printer (48) analyze the data and present the data in a useful format. The tip (64; 308) of the probe (20) is provided with storage apertures (314) for use in delivering medication via the probe member (78; 306). The probe (20) is provided with an optical fibre cable and an optical encoder (182) which is supported for rotary motion within the sleeve (69) of (68; 300) the housing for eliminating cable twist evolved during manipulation. The tip (64; 308) of the probe (20) is replaceable and provided with a frangible support (338) which prevents reuse.</p> |
