TL;DR: In this paper, a surgical instrument can comprise a channel configured to support a staple cartridge and, in addition, an anvil pivotable between open and closed positions relative to the channel.
Abstract: A surgical instrument can comprise a channel configured to support a staple cartridge and, in addition, an anvil pivotable between open and closed positions relative to the channel. The surgical instrument can further comprise a cutting member configured to incise tissue positioned captured between the staple cartridge and the anvil and, in addition, means for stopping the cutting member prior to a distal end datum, wherein the distal end datum can be defined by the distal-most staple cavity in the staple cartridge. In such embodiments, the incision within the tissue may not extend beyond the portion of the tissue that has been stapled.

TL;DR: In this article, an E-beam firing bar is used to drive staples on each side of the cut in a surgical severing and stapling instrument, which is suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil.
Abstract: A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

TL;DR: In this paper, a handle assembly, a first endoscopic portion, a motor, and a first effector are described, and the first end effector is configured to perform a first stapling function.
Abstract: A surgical instrument including a handle assembly, a first endoscopic portion, a motor, and a first end effector is disclosed. The first endoscopic portion is selectively connectable to a distal portion of the handle assembly and defines a longitudinal axis. The first endoscopic portion includes a housing adjacent its proximal portion and includes an actuation member. The motor is disposed in mechanical cooperation with the housing of the first endoscopic portion and is operatively connected to the actuation member for moving the actuation member substantially along the longitudinal axis. The first end effector is selectively connectable to a distal portion of the first endoscopic portion and is configured to perform a first stapling function.

TL;DR: In this article, a surgical cutting and fastening instrument is described, which includes an end effector comprising an elongate channel, a clamping member pivotably connected to the channel, and a moveable cutting instrument for traversing the channel to cut an object clamped in the end-effector by the clamped member when the member is in a clamped position.
Abstract: A surgical cutting and fastening instrument is disclosed. According to various embodiments, the instrument includes an end effector comprising an elongate channel, a clamping member pivotably connected to the channel, and a moveable cutting instrument for traversing the channel to cut an object clamped in the end effector by the clamping member when the clamping member is in a clamped position. The instrument may also comprise a main drive shaft assembly for actuating the cutting instrument in the end effector, a gear drive train connected to the main drive shaft assembly, and a motor for actuating the gear drive train. The instrument may also includes a closure trigger and a firing trigger, separate from the closure trigger, for actuating the motor when the firing trigger is retracted. Also, the instrument may comprise a mechanical closure system connected to the closure trigger and to the clamping member for causing the clamping member to pivot to the clamped position when the closure trigger is retracted.

TL;DR: An electrically powered tool having a hollow metallic, usually elongated handle secured at one end to a motor-receiving and tool-supporting housing, an inner, relatively rigid tube extending axially through the metallic in spaced apart relation thereto, and one or more electrical conductors each having an electrical insulation covering extending through the inner insulating tube and into the housing for connection to the tool driving motor therein for supplying operating current.
Abstract: An electrically powered tool having a hollow metallic, usually elongated handle secured at one end to a motor-receiving and tool-supporting housing, an inner, relatively rigid tube extending axially through the metallic in spaced apart relation thereto, and one or more electrical conductors each having an electrical insulation covering extending through the inner insulating tube and into the housing for connection to the tool driving motor therein for supplying operating current thereto. A handle grip may be provided at the end of the handle remote from the housing. The inner insulation tube and the insulation covering on the conductors provide a double insulation construction in the handle. The handle and insulating tube are supported in such a manner that no metallic fasteners are inserted through the walls of the handle and the insulating tube.
