Document Type and Number:
WIPO Patent Application WO/2015/133230
Kind Code:
A1
Abstract:
A cap (10) for a medical device includes a base member (11). The base member (11) is attached to a distal portion (2a) of an insertion part (2) of a medical device (1) having an endoscope (4). On the base member (11), two linking members (13) are swingably supported by shaft members (12). On distal ends of the linking members (13), a blade (15) is rotatably supported by coupling members (14). The blade (15) has a treatment hole (15a). A treatment part (3) that is inserted through the medical device (1) has a treatment distal portion (33). The treatment distal portion (33) is inserted through the treatment hole (15a). In an endoscopic submucosal dissection, the treatment distal portion (33) makes an incision between a submucosa (101) and mucous membrane (102). The blade (15) pushes up the mucous membrane (102) that is dissected from the submucosa (101), thereby enabling the treatment part (3) to be slipped under the mucous membrane (102).
