摘要： A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A traction biased firing mechanism avoids binding in driving this straightened linked rack in cooperation with an anti-backup mechanism, with a lockout mechanism that prevents releasing the closure trigger during firing. Furthermore, an external indicator gives feedback to the surgeon as to how far firing has progressed, as well as providing a manual retraction capability.

摘要： A surgical instrument particular suited to endoscopic use is disclosed. Various embodiments include an end effector that is sized to be inserted through a trocar. An elongated shaft assembly is coupled to the end effector and a control handle. The elongated shaft assembly has a distal portion that is adjacent to said the effector for insertion into the trocar. The elongated shaft assembly further has a proximal portion that is remote from the distal portion such that the proximal portion protrudes from the trocar when the end effector and distal portion are inserted therethrough. The control handle is articulatably coupled to the proximal portion of said elongated shaft assembly to enable the surgeon to move the handle portion to a more ergonomically comfortable position while carrying out the endoscopic procedure. Various articulation joint embodiments and locking arrangements are disclosed.

摘要： A surgical instrument for being endoscopically or laparoscopically inserted into a surgical site for simultaneous stapling and severing of tissue includes force adjusted spacing between an upper jaw (anvil) and a lower jaw (staple cartridge engaged to an elongate staple channel) so that the height of staple formation corresponds to the thickness of the tissue, yet does not exceed the height range that may be accommodated by the length of the staples. In particular, collapsible staple drivers may be supported within the cartridge for driving a staple or staples supported thereon into forming contact with an underside of an anvil attached to the instrument. As the staples contact the anvil, the drivers can compress or collapse to control the overall formed height of the staple or staples based upon the amount of compression forces experienced by the drivers during the stapling process.

摘要： A surgical severing and stapling instrument clamps tissue in a staple applying assembly comprising a lower jaw of an elongate channel holding a staple cartridge and a pivotally opposed upper jaw (anvil). A firing handle drives a rack in a handle connected to a firing rod and bar that pass through an elongate shaft and into the staple applying assembly to sever and staple tissue. Upon release of the firing handle, a retraction spring assists in withdrawing the rack and other firing components. To advantageously assist in firing, a spring biased plunger is cocked prior to firing to impart assistance upon depression of the firing trigger. Alternatively, a torsion coil spring ratchet mechanism is preloaded to act through a gear into the rack to assist. As a further alternative, a retraction spring is preloaded and disengaged until the rack is fully fired.

摘要： Methods and devices are provided for actuating and/or articulating a grasping device. In one exemplary embodiment, a grasping device is provided having a shaft with an end effector having opposed jaws coupled to the shaft. An electrically expandable and contractible actuator, such as an electroactive polymer actuator, can be used to actuate the end effector to open and close the opposed jaws to grasp tissue or other objects. In another embodiment, an electroactive polymer actuator can be used to pivotally or angularly adjust a position of the end effector relative to the shaft by delivering energy to the electroactive polymer actuator.

摘要： Methods and devices are provided for actuating and/or articulating a surgical stapler. In one embodiment, a surgical stapler is provided having a stapling mechanism or end effector that is movably coupled to a distal end of an elongate shaft. An electrically expandable and contractible actuator, such as an electroactive polymer actuator, can be used to pivotally or angularly adjust a position of the stapling mechanism relative to the elongate shaft by delivering energy to the electroactive polymer actuator. In another embodiment, an electroactive polymer actuator can be used to actuate the staple applying assembly, thereby driving one or more staples, and preferably at least two linear rows of staples, into tissue. The actuator can alternatively or additionally drive a blade distally to cut tissue being stapled.
