Oral health measurement clamping probe, system and method
Devices, systems, and methods determine the health of oral objects by providing objective measurements using a detachable probe body. The detachable probe body may isolate reusable system components (including an electromagnetic signal detection, signal transmission, energy generation, and or energy transmitting components) from the oral cavity, optionally by encasing at least a portion of one or more of these components in a sheath or the like. A window of the probe body maintains sterile isolation and transmits electromagnetic energy to and/or signals from the oral object. Accuracy can be enhanced by a clamp or other structure for engaging a surface of the oral object so as to maintain a fixed alignment between the signal receiver and the oral object.
1. An isolating structure for oral use, comprising:
a body having a vertically-oriented rigid first element having a portion through the first element substantially transparent to electromagnetic signals, a horizontally-oriented rigid second element, and a deformable third element on a bottom surface of the second element;
a sheath surrounding the transparent portion and sealed hermetically to the body, extending away from the body and having an opening at an end furthest from the body, the sheath providing a passage from the opening to the transparent portion for a signal probe;
wherein the third element is sufficiently deformable that with the second element positioned over a tooth in an oral cavity, bite pressure deforms the third element to conform to shape of the tooth, stabilizing the body relative to the tooth, and the sheath has a length sufficient that, with the body engaging the tooth, the opening for the signal probe is outside the oral cavity.
2. The structure of claim 1 wherein the sheath comprises an interface for engaging a probe to hold the probe stationary.
3. The structure of claim 1 wherein the sheath comprises a change of direction and a mirror for reflecting an electromagnetic signal from a probe.
4. The structure of claim 1 further comprising a joint between the sheath and the body, providing for a limited change in angle for a probe.
5. A method for isolating a probe from contaminating influence of an oral cavity, comprising the steps of:
(a) engaging a patient's tooth in an oral cavity with a structure comprising a body having a vertically-oriented rigid first element having a portion through the first element substantially transparent to electromagnetic signals, a horizontally-oriented rigid second element, and a deformable third element on a bottom surface of the second element, and a sheath surrounding the transparent portion and sealed hermetically to the body, extending away from the body and having an opening at an end furthest from the body, the sheath providing a passage from the opening to the transparent portion for a signal probe;
(b) causing the patient to bite down on the body, forcing the third element onto the tooth, stabilizing the body relative to the tooth; and
(b) inserting a probe into the sheath to a position proximate the transparent portion.
6. The method of claim 5 wherein the sheath comprises an interface for engaging a probe to hold the probe stationary.
7. The method of claim 5 wherein the sheath comprises a change of direction and a mirror for reflecting an electromagnetic signal from a probe.
8. The method of claim 5 wherein the structure further comprises a joint between the sheath and the body, providing for a limited change in angle for a probe.
