Ligation device having structure for moving retracting member configured to draw thread into device body to ligate ligation target with the thread

Abstract

A ligation device includes: a body having a cylindrical shape and extending in a longitudinal direction; a holder disposed at one end of the body in the longitudinal direction; a retractor having a part accommodated inside the body; and a drive unit connected to an other end of the body in the longitudinal direction. The holder is configured to hold a ligation target. The part of the retractor is movable toward the other end of the body in the longitudinal direction to draw a thread into an interior of the body for ligating the ligation target held by the holder. The drive unit includes a first motor for moving the retractor in the longitudinal direction relative to the body.
