System for evulsing elongated subcutaneous tissue

摘要

A system for evulsing subcutaneous tissue having an endoscope (20) to be inserted into subcutaneous tissue through a skin cut portion to observe tissue to be evulsed and existing under the skin, a dissecting unit to be inserted into the subcutaneous tissue through the skin cut portion so as to dissect the tissue, to be evulsed, from surrounding tissue in order to form a cavity along the tissue to be evulsed and below the skin, a cavity maintaining unit (62, 672) to be inserted from the skin cut portion into the cavity formed by the dissecting unit and to be retained in the cavity in order to maintain, around the tissue to be evulsed, a treatment space which permits the endoscope (20) to be inserted and removed and which enables treatment of the tissue to be evulsed, and at least one treatment tool (91, 92, 130) to be inserted into the treatment space maintained by the cavity maintaining unit (62, 672) in order to perform, in the treatment space, treatment required to evulse the tissue to be evulsed.
