ABSTRACT:
Disclosed is a catheter used to pick a sample of a lesion cell tissue existing in the living body, and more particularly a catheter capable of freely coupling or separating a micro biopsy tool and picking a tissue required for an examination just by inserting and extracting the biopsy tool into and from a lesion region when picking the tissue. The catheter can pick a tissue required to diagnose and treat an examinee with a minimal invasion. Accordingly, it is possible to alleviate the examinee's pain and to prevent a perforation from occurring in the picked region when picking the tissue. In addition, according to the catheter of the invention, since the micro biopsy tool can be easily mounted and separated, the catheter can be semi-permanently used by continuously replacing the biopsy tool only.
