Technical field
The present invention relates to a kind of ultrasound knife amplitude detecting device, particularly a kind of ultrasound knife amplitude detecting device that utilizes common medical stereomicroscope as the testing platform.
Background technology
Ultra-sonic operation device is a kind of novel operation device that begins to develop rapidly the 1980s, is called as the important breakthrough of international medical community.It is compared with electric knife, laser knife, microwave coagulation treatment, have the tissue damage around operative site or the section little, hemorrhage few (even not hemorrhage), surgical field of view is clear, a series of outstanding advantages such as operation risk is little, and is safe, easy to operate, extensively applied to surgical fields such as ophthalmologic operation, neurosurgery, oncotherapy, become both at home and abroad competitively one of high-tech medical product of exploitation.
At present, generally believe both at home and abroad as judging whether qualified key parameter is the axial offset of hand-held treatment head operator point when ultrasonic generator is worked to ultra-sonic operation device, promptly treat the amplitude of head, general amplitude range is 32～350 μ m, amplitude is too small can to influence surgical effect, prolongs operating time, if amplitude is crossed hand-held difficulty and the manufacturing cost that conference increases hand-held treatment head on the other hand, reduce serviceable life, therefore generally all its amplitude is set between 200～350 μ m.
Still there is not an effective checkout equipment to the measurement of a hand-held treatment amplitude is domestic, general all continue to use method that general in the world tool microscope carries out Direct observation and measured and judge, this method is on the one hand because the cost of tool microscope is very high, the microscopical acquisition cost of separate unit is about 170,000 dollars, on the other hand owing to need manually to be judged by the dynamic image in the polariscope in the viewing microscope, error is big, and testing staff's work load is bigger.
In addition, medical institutions as the Vltrasonic device applying unit, for the operation quality is responsible for, must regularly carry out measurement verification (i.e. example inspection) to the ultrasound knife of being purchased, to judge whether it is qualified, and the employing conventional detection, expensive original equipment cost is a white elephant to general curative mechanism.
Summary of the invention
