Tooth operation.
Background technique
Intelligent operation technology combines advanced diagnostic techniques and accurate surgical procedure device, so that the effect of operation exists
Many aspects are better than the traditional operation operated by doctors experience.Currently, removing dental caries in the surgical procedure of saprodontia
The surgical procedure for becoming tissue relies primarily on the experience of doctor, there are pathological tissues in the course of surgery and removes unclean or removed
The case where more health tissues.The former leads to the risk of recurrence for it, and the latter then causes unnecessary loss to patient, therefore, more
Accurate intelligent tooth treatment operation is added urgently to develop.
The laser pulse of focusing can puncture substance and generate the effect for degrading sample, can be in sample surfaces some tens of pm
A small amount of sample is removed in magnitude.And puncture the composition information that the plasma resonance that substance generates is able to reflect out substance.Cause
This, pulsed laser technique is applied in tooth operation, can develop novel side that is a kind of while realizing diagnosis and surgical functions
Method is expected to promote and apply in manual operation intelligent operation even full automatic intelligent operation.And related device is then necessary
Consider the limitation for surgical procedure of Human Oral Cavity structure and Tooth Size shape, therefore the scheme proposed must have and be suitble to make
It is designed with the configuration design of environment and light channel structure, can just develop the intelligent operation device that can be applied and promote.
Summary of the invention:
Has focus positioning the present invention relates to one, laser focuses and the operation device of three functions of signal collection.It should
Device utilizes its positioning probe and piezoelectric triggering mechanism, realizes the positioning of intended operating location；Using its laser fiber and gather
Focus lens introduce laser pulse, puncture, degrade dental surface, and generate plasma；Using its condenser lens, dichroscope,
Collecting lens and signal optical fibre composition collect optical path, realize the collection of spectral signal, the lesion of tissue is judged according to spectral signal
Degree controls the output of laser pulse, and then realizes diagnosis and surgical procedure.
