An endoscope treatment tool includes an insertion part that is insertable into a first treatment tool channel of an endoscope of an endoscope system, an operation part, and a single operation wire pulled through operation of the operation part. The insertion part includes a distal end portion that has an openable and closable grip portion, a bending portion that is able to be bent, and a connecting-portion that connects the bending portion to the operation part. The connecting-portion is moved forward and backward along a longitudinal axis of the connecting-portion and is rotated about the longitudinal axis. As the connecting-portion is moved forward and backward or is rotated, the grip portion moves forward and backward or rotates, through the operation of the operation part. As the operation wire is pulled, the grip portion is closed, and the bending portion bends in a state where the grip portion is closed.

Hemostatic Device

A hemostatic device is provided with: a first tubular member; a positioning member having a first engagement section and engageable with an opening of a blood vessel; a hemostatic agent arranged further to a proximal end side than the first engagement section of the first positioning member; a push-out member making it possible to push the hemostatic agent out from a distal end section of the first tubular member when the push-out member is moved; a first operation unit for executing a first distal end operation for causing the first tubular member and the push-out member to move in a relative manner to a distal end side, and a second distal end operation for causing the push-out member to move in a relative manner to the distal end side; and a switching mechanism for restricting the second distal end operation until the first distal end operation is completed.

Battery-powered hand-held ultrasonic surgical cautery cutting device

A battery-powered, modular surgical device comprising an electrically powered surgical instrument that requires a pre-determined minimum amount of electrical energy to complete a surgical procedure, and a power module assembly that has a battery that powers the surgical instrument and has a current state of electrical charge, and a control circuit that is electrically coupled to the battery and the surgical instrument and has a memory and a microprocessor. The microprocessor determines the current state of electrical charge of the battery, compares the current state of electrical charge to the pre-determined minimum amount of electrical energy, permits the battery to discharge if the current state of electrical charge is above the pre-determined minimum amount of electrical energy, and maintains the battery in a non-discharge state if the current state of electrical charge is below the pre-determined minimum amount of electrical energy.

DEVICE FOR SUTURE ATTACHMENT FOR MINIMALLY INVASIVE HEART VALVE REPAIR

Disclosed herein are minimally invasive systems and methods for intravascularly accessing the heart and performing a transcatheter repair of a heart valve by inserting a suture as an artificial chordae into a heart valve leaflet. In various embodiments, such systems and methods can be employed in other heart valve repair procedures such an edge to edge repair to coapt leaflets by inserting one or more sutures that retain the leaflets in a coapted positioned or inserting a suture to repair a tear in a leaflet, for example.

Surgical stapler with end of stroke indicator

A surgical instrument and method for indicating that a cartridge has been fired includes an end effector receiving a cartridge having at least one of a knife and a plurality of staples, a shaft assembly connected to the end effector, and a handle assembly. The handle assembly has a handle housing, a firing member configured to selectively actuate from a first position to a second position as a firing stroke, and a feedback generator operatively connected to the firing member. The firing member is configured to actuate the cartridge from an unfired cartridge position to a fired cartridge position when the firing member is actuated. The feedback generator is configured to communicate an audible sound and a visual indicia to an operator indicative of the firing member completing the firing stroke for actuating the cartridge to the fired cartridge position.

Endoscopic treatment instrument, treatment instrument unit, and treatment system

An endoscopic treatment instrument includes a guide sheath. The guide sheath includes a second distal end, which has an inside diameter to insert the insertion portion therethrough so that the distal end of the insertion portion is configured to protrude relative to the second distal end. The guide sheath is inserted through the guide pipe so that the second distal end is configured to protrude relative to the first distal end of the guide pipe.
