An exemplary surgical stapler may include a staple holder, staples positioned within the staple holder, and at least one structure slidable within the staple holder to contact directly at least one staple, where that direct contact deploys at least one staple from the staple holder. Another exemplary surgical stapler may include a staple holder, an anvil movably connected to the staple holder, staples positioned within the staple holder; and a sled slidable within the staple holder to contact directly at least one staple, where that direct contact urges at least one staple out of the staple holder and against the anvil.

An anastomosis tool may include a tissue effector having an anvil and a staple holder movable relative to one another, where that tissue effector may be movable from an open position to a closed position. A fluid-driven actuator may be utilized to move the tissue effector between those positions, and/or to deploy connectors from the staple holder when the tissue effector is in the closed position. The fluid-driven actuator may utilize pressurized gas stored in a cylinder or reservoir within the anastomosis tool. A separate clip applier may be used to close the entry hole made by the anvil in a target vessel.

A method of performing anastomosis between a graft vessel and a target vessel, each having a circumferential wall and a lumen therethrough, may include providing an anastomosis tool including a tissue effector and a fluid-driven actuator operationally connected to that tissue effector; connecting the fluid-driven actuator to an energy source; placing an end of the graft vessel in proximity to the side of the target vessel; and actuating the fluid-driven actuator to connect the end of the graft vessel to the side of the target vessel.

A system for performing anastomosis between a graft vessel and a target vessel includes a tissue effector that may be configured to deploy a user-selectable number of connectors. The system includes an anvil that enters the wall of the target vessel through an entry hole that is spaced apart from the anastomosis site, and at least one anvil entry hole sealer may be utilized to substantially seal the anvil entry hole upon withdrawal of the anvil. The system may include a shield and a cutter, both of which are movable relative to the anvil, where the shield is configured to protect the graft vessel from the cutter. The cutter may include an incising element movable from a stowed position to an active position.

An exemplary surgical apparatus may include a flexible articulation insert and at least one feeder belt extending through the articulation insert, where at least some of the staples are frangibly connected to the feeder belt. Another exemplary surgical apparatus may include at least one movable feeder belt; staples fixed to the feeder belt; and a flexible articulation insert having at least one feeder belt passage defined therein, the flexible articulation insert configured to bend through a range of motion; where each feeder belt extends through a corresponding feeder belt passage, and where each feeder belt passage is shaped such that the corresponding feeder belt and staples fixed thereto are slidable along the passage throughout the entire range of motion of the flexible articulation insert.

One example of a surgical method of treating tissue within the body of a patient may include providing a surgical instrument that includes a handle; a shaft extending from the handle, an end effector connected to the shaft, where the shaft includes a lumen defined therethrough and an articulated region; and at least one feeder belt extending through the lumen of the shaft into the end effector, where the feeder belt includes at least one staple frangibly united therewith; inserting the end effector into the body of a patient; orienting the end effector relative to tissue to be treated within the body of the patient and relative to a remainder of the shaft; actuating the end effector to staple tissue; and removing the end effector from the body of the patient.
摘要:
An anastomosis tool includes a handle connected to a tissue effector that may be capable of being oriented in two or more positions relative to the handle. The tissue effector holds a graft vessel having at least one flap defined in at least one end thereof against the side of a target vessel. Actuation of a trigger or other mechanism on the handle causes the tissue effector to deploy one or more connectors into the flaps of the graft vessel and the side of the target vessel, thereby connecting the graft vessel to the target vessel.
摘要:
An exemplary surgical apparatus may include an end effector; a shaft extending proximally from the end effector, the shaft including an articulation region; and a handle including at least one button, where actuation of the button causes said the effector to articulate through a discrete increment relative to the shaft.

One example of a surgical apparatus may include at least one resorbable feeder belt, and a plurality of staples fixed to that feeder belt. Another example of a surgical apparatus may include at least one feeder belt and at least one resorbable carrier detachably connected to a corresponding feeder belt, where the carrier includes a plurality of staples attached to it. An exemplary surgical method of treating tissue within the body of a patient may include providing a surgical instrument that includes an end effector moveable between an open configuration and a closed configuration, where the end effector includes an anvil and a staple holder pivotally connected to one another, where the anvil holds a knife; and at least one resorbable feeder belt and a plurality of staples fixed to the feeder belt, where the feeder belt extends into said staple holder; placing the end effector in proximity to tissue; deploying a plurality of staples into tissue; separating a distal segment of at least one feeder belt from a remainder of that feeder belt; and leaving that distal segment within the body of the patient.
摘要:
An exemplary surgical apparatus may include a feeder belt; wings fixed to that feeder belt; and a die into which the feeder belt extends, where relative motion of the die and feeder belt bends at least one wing to transform at least one wing into an unformed staple. An exemplary surgical method for treating tissue of a patient may include providing a surgical instrument including an end effector; placing the end effector adjacent to tissue of a patient; and manufacturing at least one surgical staple within the end effector.
