A ligating apparatus including a thread receiving portion movably disposed at a distal end of an inserting part body. An outer circumference of the thread receiving portion forms the loop holding portion around which a knot forming loop formed from a ligature is disposed. When a first end of the ligature is pulled into the thread receiving portion, the knot forming loop is pushed out of the loop holding portion by a delivery portion of the knot pusher. The knot forming loop is further pushed by the delivery portion along the ligature toward tissue and ligated. Such ligating apparatus is capable of reducing a load on the tissue to be ligated during a ligating operation.

Ligating apparatus

The endoscopic treatment instrument includes an insertion portion; a treatment portion; and a control portion. The treatment portion includes a pair of forceps members; a tip cover; a distal end holding portion that is fixed to a distal end of the insertion portion; a distal end locking member that restrains a relative movement by locking the tip cover onto the distal end holding portion; and a distal end release member that is provided on an operational member by which the pair of forceps members is opened and closed and that releases an engagement made by the distal end locking member between the tip cover and the distal end holding portion at least when the pair of forceps members is closed.

Endoscopic treatment instrument and retaining device

There is provided an endoscopic system. The system comprises a flexible endoscope insertable into a first tubular organ from a natural opening of a human body. The system further comprises an opening member which forms on a wall part of the first tubular organ an opening used to insert the endoscope into an abdominal cavity from the first tubular organ in the body, an anastomosing member which is able to anastomoses the first tubular organ with a second tubular organ in the abdominal cavity, and a cutting member with which the second tubular organ is able to be cut.

Anastomosis system

An endoscopic treatment instrument having a treatment portion having: an input member; a first link disconnectably connected to the input member; a first control plate disposed in a first connecting portion, inserting the input member through the first control plate, and engaging the input member by inclination of the first control plate; a first forceps member opening and closing according to advancing and retracting motions of the first link; a second link disconnectably connected to the input member; a second control plate disposed in a second connecting portion, inserting the input member through the second control plate, and engaging the input member by inclination of the second control plate; and a second forceps member opening and closing according to advancing and retracting motions of the second link, the opening-and-closing angle of the second forceps member being less than that of the first forceps member.

Endoscopic treatment instrument
