The production method for piercing training pattern.
Background technology
It is to apply a kind of special puncture needle with flexible conduit through Aspiration-needle biopsy art, passes through fiber branch
The biopsy duct of airway wall is sent into air flue, is then penetrated airway walls to lesion outside trachea-bronchial epithelial cell chamber, such as tubercle, lump, is swollen
The lesion of big lymph node and lung is drawn into hand-manipulating of needle piercing and sucking, is obtained cell or tissue sample and is carried out cytology and pathological examination
A kind of new technology.It is widely used in being close to the etiologic diagnosis of lesion around trachea-bronchial epithelial cell through Aspiration-needle biopsy art,
And bronchoscope technology is made to participate in the clinical stages of malignant tumour, but before the grasp that is skilled in technique to this, do not allow
Patient body directly operates.And training at present mostly virtual bronchoscopic analogue technique and fabric bronchoscope training box, these
Though the prior art can carry out operation training, each tissue of respiratory system, organ model specific form and true also have
Gap, relative tertiary location and adjacent structure are not definite enough, and the selection of material is also unreasonable, and training pattern bronchus structure thousand
A piece without exception, does not have difficulty difference, so cannot reach clinical practice requirement well, trainer cannot skillfully grasp through bronchus
Flow, skill and the gimmick of mirror needle biopsy art operation.
3-D scanning is mainly used for being scanned object space shape and structure and color, to obtain the sky of body surface
Between coordinate, the data collected can be used for three-dimensional reconstruction calculating, create the digital model file of actual object, have height
Efficiency, high-precision feature.Three-dimensional printing technology can be glued based on digital model file with powdery metal or plastic etc.
Condensation material constructs object by layer-by-layer printing.
Invention content
