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.

Surgical stapling instrument with an articulatable end effector

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.

Articulating surgical stapling instrument incorporating a two-piece e-beam firing mechanism

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.

Powered surgical instrument

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.

Motor-driven surgical cutting and fastening instrument with tactile position feedback

A device for retracting edges of an incision in a surface to form an opening including: a flexible, tubular skirt having an upper end, a lower end, and a channel therebetween; a ring connected to the lower end of the skirt for maintaining the lower end in an open configuration and defining an exit opening to the channel; and an inflatable collar connected to the skirt and surrounding the upper end. The ring is designed to fit through the incision and remain under the surface when it is oriented parallel to surface. The collar, when inflated, maintains the upper end in an open configuration and defines an entry opening to the channel. During use, the ring is inserted through the incision and the collar is inflated while remaining outside of the incision, thereby drawing the skirt against the edges of the incision and retracting the edges of the incision to form the opening. The retracting device can be included in a surgical access port, which further includes a flexible sleeve connected to at least one of the inflatable collar and the skirt, extending the channel from the exit opening of the skirt to an open end of the flexible sleeve distal to the skirt. The device can include a light source in the vicinity of the exit opening.

Surgical access port and laparoscopic surgical method

A lens warming and cleaning device (110, 210, 310, 410) is used to warm and clean the lens (14) and/or distal portion (16) of an optical instrument such as a laparoscope (10). The warming and cleaning device includes a heat conducting tube (114, 214, 314, 414) sized and shaped to receive the lens of the optical instrument, a heating pad (120, 220, 320, 420) thermally coupled to an exterior of the tube, and a cleaning member in the form of a sponge (116, 216, 316, 416) disposed within the tube such that when the lens of the optical instrument is inserted into the tube, the lens contacts the sponge. A moistening mechanism in the form of a squeeze bottle (118, 418) containing a saline solution can be in contact with the sponge so that a surgeon can squeeze the bottle to moisten the sponge.

Surgical access port and method for accessing a patient's body cavity

PROBLEM TO BE SOLVED: To provide a hermetical seal of a hand or an implement to be inserted into a patient's body cavity through an opening. SOLUTION: A device for retracing edges of an incision in a body surface to form an opening has a flexible tubular skirt having an upper end, a lower end and a channel, therebetween, a ring connected to the lower end of the skirt for maintaining the lower end in an open configuration and defining an exit opening to the channel, and an expandable collar connected to the skirt and surrounding the upper end. In this case, the ring is designed to fit through the incision and remain under the surface when it is oriented parallel to the body surface. When expanded, the collar holds the upper end of the skirt in an open configuration and defines an inlet opening to the channel. During use, the ring is inserted through the incision. The collar is expanded while remaining outside of the incision to draw the skirt against the edge of the incision and to retract the edge to from the opening. COPYRIGHT: (C)2001,JPO
