Abstract
A medical ligating apparatus includes a medical ligating device having a member which is made of a flexible line and ligates living tissues, and a fixing member which is movably provided at the ligating member and fixes the living tissues in a ligated state, a manipulating device having a flexible sheath and a proximal manipulating section, and a cutting member for cutting the ligating member. The cutting member is provided on the manipulating device and is movably provided on the ligating member.
Claims11
A manipulating device for manipulating a medical ligating device, comprising;
- an inner sheath, at least a distal end side of which is introduced into a body and holds the medical ligating device having a ligating section adapted to ligate a target;
- a proximal manipulating section provided on a proximal end side of the sheath;
- a manipulating wire which is inserted in the sheath, the manipulating wire having an engagement member at its distal end portion which is engageable with a proximal end portion of the medical ligating device;
- a wire operating device provided on the proximal manipulating section and connected to a proximal end portion of the manipulating wire;
- a cutter which includes at least one blade directed in a proximal end direction of the sheath, and which is movable relative to the sheath in the proximal end direction thereof, the cutter moving relative to the sheath to cut two portions of the medical ligating device between the ligating section and the proximal end portion to keep the medical ligating device in the body;
- and
- a cutting operation member provided on the proximal manipulating section and connected to the cutter to move the cutter relative to the medical ligating device in the proximal end direction of the sheath.
A manipulating device for manipulating a medical ligating device, comprising;
- an inner sheath, at least a distal end side of which is introduced into a body and holds the medical ligating device having two leg portions and a ligating section adapted to ligate a target;
- a proximal manipulating section provided on a proximal end side of the sheath;
- a manipulating wire which is inserted in the sheath, the manipulating wire connected to a proximal end portion of the medical ligating device;
- a wire operating device provided on the proximal manipulating section and connected to a proximal end portion of the manipulating wire;
- a cutter which includes at least one blade directed in a peripheral direction of the sheath, and which is rotatable relative to the sheath about a rotating axis extending a longitudinal direction of the inner sheath to cut the leg portions of the medical ligating device to keep the medical ligating device in the body;
- and
- a cutting operation member provided on the proximal manipulating section and connected to the cutter to rotate the cutter relative to the medical ligating device.
