摘要: The invention discloses an extractor for a pathological tissue during surgery. the surgery comprises needle tubing, piston assembled inside push-pull rod which controls to move and arranged at front end of tubing. pinpoint is circular opening. A stem provided with extraction cavity can slide along needle. connected through connecting rod. dedicated instrument rapidly conveniently carry out pathology extracting provided, structure simple, operation convenient, cost low. Due fact that designed, under condition moving not influenced, influence on other tissues possibly lowered, bleeding rate accuracy cell improved. By arranging position structures such as cavity, extracted by totally enter cannot be maintained into needle, directly taken from rear portion injector, collecting process greatly convenient.
