마이크로 스파이크로 채취한 조직의 진단을 위한 미세 조직회수도구

Abstract

We have developed and reported several micro-spikes for minimally invasive biopsy. In this paper, a micro-tissue collecting tool for tissue diagnosis extracted by micro-spike is presented. Using proposed polydimethy-siloxane (PDMS) micro-tissue collecting tool, which has a negative micro-spike structure in a porous chamber, the extracted tissue in a micro-spike is effectively detached. The gastro-intestinal tissue of a pig is extracted in an in vivo environment, and then it is detached from a micro-spike using the PDMS micro-tissue collecting tool. A fine clinical picture of the detached tissue is acquired
