A treatment device includes: an end effector that includes a pair of grippers for gripping a target region; a channel for supplying a fluid to the end effector; and a fluid source for supplying the fluid to the channel. The treatment device is capable of controlling fluid flow to the end effector based on an open or closed state of the end effector.

Treatment device

A high frequency treatment instrument can be opened and closed between a first grasping jaw and a second grasping jaw. A lumen is formed inside the first grasping jaw. The first grasping jaw includes an electrode disposed on a side toward which the first gasping jaw is closed, with respect to the lumen. The electrode has an electrode surface arranged opposite the second grasping jaw and extending from a proximal end portion to a distal end portion of the first grasping jaw. The first grasping jaw has a distal end wall disposed opposing from a distal end side of the first grasping jaw toward a distal end edge of the electrode surface, and a clearance between the distal end edge of the electrode surface and the distal end wall communicates to the lumen and opens toward the side toward which the first grasping jaw is closed.

High frequency treatment instrument

An endoscopic device includes a longitudinal member, a pair of jaws installed at a distal end of the longitudinal member and configured to be freely opened and closed, a first grasping member supported by a first jaw of the pair of jaws, a second grasping member supported by a second jaw of the pair of jaws, the second body having a wire shape, flexibility, and being curved in a loop shape, a long operating transmission member having a distal end portion connected to the pair of jaws and installed to advance and retreat along a longitudinal axis of the longitudinal member, and an open-close operating portion installed at a proximal end portion of the operating transmission member and configured to be manipulated to open and close the pair of jaws.
