    摘要： An improved surgical stapler includes a stapler body having a driver and a magazine connected to the stapler body. The magazine includes a staple track for carrying a plurality of staples and an anvil associated with the staple track. The anvil has a staple forming surface for forming each of the staples thereon. A trigger is operatively connected to the driver for advancing the driver against the anvil so as to form the staple against the staple forming surface of the anvil. A feeder for feeding each of the staples from the staple track to the anvil is movably mounted in the magazine. A pinion is operatively connected to the trigger and is movably engaged with the feeder. An indexing member is movably engaged with the pinion such that the indexing member and the pinion advance the feeder and the staples toward the anvil upon an actuation of the trigger.

    摘要： A surgical instrument that includes a distal member configured to receive a pneumatically operated tool assembly therein. The instrument may also include pneumatically powered drive member configured to generate at least one actuation motion upon receipt of at least one pneumatic signal from a source of pneumatic power fluidically coupled thereto. A drive shaft assembly communicates with the pneumatically powered drive member for transmitting the actuation motions to the distally mounted pneumatically operated tool. The device further includes a power assist member that communicates with the drive shaft assembly for transmitting additional manually generated actuation motions to the drive shaft assembly.

    摘要： A surgical instrument that includes a distal member configured to receive a pneumatically operated tool assembly therein. The instrument may also include an elongate shaft assembly that has a distal end portion that is coupled to the distal member and a proximal end portion. A drive member may be supported by the distal end portion of the elongate shaft assembly and may be configured to apply at least two actuation motions to the pneumatically operated tool assembly upon receipt of at least one pneumatic drive signal from a source of pneumatic power. The drive member may comprise a dual-acting cylinder, a single-acting cylinder, a bellows assembly, etc. The distal end portion of the elongate shaft member may articulate relative to the proximal end portion thereof and/or the distal end portion of the elongate shaft assembly may be detachable from the proximal end portion.
