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.

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.

In various embodiments, a surgical stapler (1) is provided that may comprise a body (10), a stapling head (30) operably coupled to the body, an anvil (50) movably supported relative to the stapling head for selective travel toward and away from the stapling head, and an anvil adjustment shaft (70) supported by the body for selectively adjusting a position of the anvil relative to the stapling head. The adjustment shaft and/or the body may be configured to establish at least one predetermined staple forming height between the anvil and the stapling head irrespective of adjustment shaft rotation. Additionally, the adjustment shaft and/or the body may be configured to provide tactile feedback to a user rotating the anvil adjustment shaft, thereby providing the user of an indication of when an appropriate staple forming height has been reached. Various integrations of components described herein may also reduce the part count required for a surgical stapler, thereby reducing assembly time and manufacturing cost.

In various embodiments, a surgical stapling head is provided that may comprise a staple cartridge for supporting one or more staples, a core movable relative to the staple cartridge, at least one staple driver extending from the core, and a casing configured to at least partially hold the staple cartridge and movably receive the core and the staple driver(s). The casing may further comprise at least one retention member that is configured to move from a first position to a second position when sufficient external force is applied to the retention member, such as that provided by a shaft of a surgical stapler during insertion of the stapling head assembly into the shaft. When the retention member(s) are at the second position, the staple driver(s) may be prevented from driving staples from the staple cartridge, thereby providing a firing lockout feature to the stapling head assembly during insertion into at least a portion of a surgical stapler.

An electrosurgical device comprises an end effector, a cutting member, and en electromechanical driver. The end effector comprises a pair of jaws that clamp tissue. The jaws include electrodes that deliver RF energy to clamped tissue. The cutting member cuts tissue clamped between the jaws. The electromechanical driver drives the cutting member. A control module commands the electromechanical driver, and regulates the delivery of RF energy to the electrodes, based on a combination of user input and feedback signals from the electrodes and from the electromechanical driver. The device may provide tactile feedback to the user through the user input feature, based on a load encountered by the cutting member. The device may alert the user when the exterior of end effector makes incidental contact with tissue, to avoid inadvertently burning the tissue. The device may include a removable battery pack to power the electromechanical driver and the electrodes.

Motor driven electrosurgical device with mechanical and electrical feedback

Hand-held surgical instruments that have and end effector attached to an elongate shaft are disclosed. The end effector is articulatable and rotatable relative to the shaft by a nozzle arrangement supported by a handle from which the elongate shaft extends. In various embodiments, the nozzle is operable by the same hand that is used to support the handle.

Surgical instruments with articulatable and rotatable end effector

Modular surgical instruments are disclosed. In various embodiments, a modular surgical instrument t is disclosed for use with a plurality of interchangeable surgical tool heads that are configured to perform different surgical actions. The instrument is configured to apply a plurality of different rotary drive motions and axial drive motions depending upon the type of surgical tool head attached thereto.
