1、Before inserting the needle to biopsy hole, pull the steel wire cap outward, and confirm the needlepoint is located in metal helmet on end section.
2、Withdraw the needle in the puncture needle tube under direct vision of endoscope, and the assistant fixes steel wire cap at the joint of needle tube and steel wire cap.
3、Send needle to lesion.
4、The assistant sucks the work drum to position of 10ml with negative pressure, lock and fix piston, then take sample.
5、Remove negative pressure.
6、Release fixing of steel wire cap and needle tube, withdraw the needlepoint to the back of needle tube helmet, take puncture needle out of body through tong passage cavity.
7、Align needle to slide, thrust out needlepoint, push sample on slide through injecting gas in work drum, then fix the sample to 95% alcohol for inspection.
