Long structure dissection and opening creation the device and method in order to do

摘要

(57) Abstract Solutions The dissection instrument which has the balloon (12) which possesses with contractile state and expansion state/the opening creation vessel device (10) is disclosed, minimum invasive characteristic surgical operation procedure is executed by drawing up the tunnel on side side of target organization of internal. The balloon (12) crossing the balloon (12) regarding the expansion state, forms the opening space (16) which extends. The balloon (12) is supported by the insertion assembly body (14). The balloon (12) being long torus form, inside that has the long opening section territory. The insertion assembly body includes with the sluggish dissection device and handle (22). At the time of use, the dissection instrument/the opening creation vessel being inserted through small incision, in body organization is inserted to position of desire the moat and others re it is sluggishly the tunnel (10) through. The balloon (12) expanding in order to draw up the space in while body organizing, the dissection of the organization which responds necessary from the organization which it should deal with does. Expanding to specified position, being left, the space opening creation it does the balloon (12). Doing the incision of other things, than first incision it is possible to offer the access to direct target organization. Target organization after that, diagnosis and/or is dealt with through direct access incision, through coating organization, through the opening space (16) of the balloon (12).
