System method includes enzyme digestion and tissue mass cell culture.Since both approaches usually need to sacrifice donor to obtain complete gas
Pipe epithelial tissue, causes the subsequent experimental process such as orthotopic transplantation to be affected.
Airway epithelium is obtained using bronchoscope combination auxiliary device, is the new of noninvasive acquisition primary cell in recent years
Method.Under the branchofiberoscope being commonly used, the method that is gripped by conventional bronchoscope biopsy forceps.This method has
There is the features such as easy to operate, damage is small, postoperative care is easy, it is gradually widely used by educational circles.Its cardinal principle is：Through Bronchofiberscope
Into patient airway, after searching out preferable materials position, first degermed and mucus with a large amount of normal saline flushings with removing, Ran Houjing
Respective channel is inserted into conventional bronchoscope biopsy forceps on bronchoscope.The simple structure of this kind of biopsy forceps, mainly by caliper, seal wire
Formed with handle, itself do not possess any steering, absorption, apply external force function.When the caliper that opening is seen under Bronchofiberscope arrives
Up to after being satisfied with position, the folding of caliper is controlled by drawing handle draw ring.Airway mucus tissue firmly " is bitten ", will through former passage
Seal wire, caliper take out together with tissue, give laboratory cultures.
And currently available technology is primarily present following defect：A, the group taken in the big airways such as tracheae, main bronchus can not be clamped
Knit, since tracheae wall surface is straight and smooth, the bending only according to camera lens is difficult to make biopsy forceps put forth effort on tube wall, when closure pliers
Shi Changchang is sliped off, and is lived smooth tracheal wall so as to " can not sting ", is caused operation failure；B, bronchus crotch is damaged repeatedly, carefully
Cytoactive is poor, due to cannot draw materials on straight tube wall, the natural bronchus crotch (bronchus ridge) in bulge-structure into
The position drawn materials repeatedly, since bronchus ridge numbers at different levels are very limited, after drawing materials repeatedly the position occur scar hyperplasia,
Epithelial cell is reduced, squamous metaplasia even has canceration may；C, precision of drawing materials is low, and materials position is random, due to respirometric
Influence and the limitation of bronchoscope performance accuracy itself, it is difficult to take position to accomplish to be accurately positioned for pincers, cause materials to have
Very big randomness, often clamps the tissue block got and contains a large amount of clots or mix cell, add research cost, reduce and grind
Study carefully quality.
Therefore, for that can not put forth effort for straight smooth (branch) tracheal wall in traditional biopsy forceps the problem of, how to provide
A kind of materials on tracheal wall simultaneously improve the precision of materials, are that the technology that those skilled in the art are faced at this stage is difficult
Topic.
