Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of single negative pressure source list air flue rotary cutting apparatus.
Background technology
During clinical treatment, generally require to internal pathological tissues (or other tissues to be detected) sample detecting, with
Assign a cause for an illness, be mainly vacuum (negative pressure) rotary cutter using most internal pathological tissues sample devicess.Vacuum rotary cutter
During rotary-cut, both sides negative pressure is needed：One is negative pressure that peeling knife Gutron crosses that sample room obtains, in rotary-cut
Tissue sample is sucked into knife pipe, and tissue sample is sucked into sample room after rotary-cut is complete；Another is the lateral of rotary-cut sampling storehouse
Negative pressure, for adsorbing in rotary-cut sampling storehouse pathological tissues in order to cutter rotary-cut in rotary-cut.
But the negative pressure source of the above-mentioned two air flue of existing rotary cutter is independently arranged, in actual samples process mistake, it is difficult to
Hardness and adhesiveness in advance by the design of pressure of two air flue negative pressure sources with pathological tissues is matched.If the connection of sampling storehouse
Air flue negative pressure it is too small, then it is weaker to the absorbability of pathological tissues to sample storehouse, and then causes the pathological tissues of absorption can not
Die cavity full of peeling knife pipe, (in the effect of negative pressure source when the pathological tissues for cutting away do piston movement in the air flue of peeling knife
Under, the pathological tissues for cutting away along the air flue of peeling knife to sample collection box in move) often because gas leakage rests on rotary-cut
Can't pump out in the air flue of knife；If the negative pressure of the air flue of sampling storehouse connection is excessive, the pathological tissues in suction sampling storehouse can be made
Excessively, the airway blockage of peeling knife pipe is easily caused when moving in the atherectomy catheter after cutting away；Therefore, this rotary cutter takes
