Description
Technical field
The present invention relates to simulation auxiliary device technical fields more particularly to a kind of change internal diameter to simulate bronchus endoscope and image processing device.
Background technique
Bronchoscope is suitable for doing the observation of the lobe of the lung, Duan Jiya segmental bronchus lesion, biopsy sampling, bacteriology, cytology
It checks, cooperation TV system can photograph, teaching and dynamically recording.The bronchoscope has biopsy sampling mechanism, can help to send out
Existing early lesion can carry out the internal surgical operations such as polyp excision, and for bronchus, lung disease research, postoperative inspection etc. is one
The good precision instrument of kind.
Endoscopy of bronchus art is the mature operation that developed recently gets up, since bronchus scope can be by electronic display
Show that equipment observes patient from glottis to endotracheal situation in real time, therefore can more intuitively carry out hand under visual pattern
Art.
Traditional simulated training is the actual conditions realized on medical dummy, but can not observe intubation, is unfavorable for seeing
Examine study.
Magnetic grid is a kind of High-precision position detection device, it by magnetic scale, pick up magnetic magnetic head and detection circuit forms.It is
With pick up magnetic principle work.Firstly, the square wave of certain wavelength or sinusoidal signal are recorded on magnetic scale with record magnetic magnetic head, so
Afterwards according to the signal for picking up magnetic magnetic head and being picked up with magnetic scale relative displacement, displacement is detected.Magnetic scale can be used for length
And angle measurement, have precision is high, is responsible for simple and mounting and adjusting to facilitate, the disadvantage is that magnetic grid and magnetic head spacing cannot mistakes
Greatly, it is usually no more than 2mm.
