Steerable surgical stapler

Abstract: Embodiments include a surgical device and a method. An embodiment of the surgical instrument includes at least one grasping jaw, the at least one grasping jaw being adapted to deliver surgical staples by a force generated from a force generator mechanism that is contained within the at least one grasping jaw or is in a proximity to the at least one grasping jaw. Another embodiment includes at least one grasping jaw, at least one delivery mechanism adapted to deliver surgical fasteners, the delivery mechanism being located in a proximity to or contained within the at least one grasping jaw, the surgical fasteners containing at least one shape-transforming material, at least one sensor, at least one chemical tissue sealant and at least one cutter. A method includes: grasping a body organ/tissue with at least one grasping jaw, adjusting a configuration of the grasping in response to a signal or a datum or an image, and releasing a surgical staple/fastener in response to the signal, datum or image.

Vasculature and lymphatic system imaging and ablation associated with a reservoir

Abstract: In an embodiment, a system includes one or one or more reservoirs responsive to control circuitry for receiving target(s) associated with one or more blood or lymph vessel of a subject. The system includes one or more first energy source associated with the one or more reservoirs for providing energy to elicit image response(s) associated with the target(s). The system includes one or more sensors associated with the one or more reservoirs for capturing the image response(s). Control circuitry is provided and coupled to the sensors for at least partially identifying the target(s) based at least partially on the captured image response(s) during an expected transit time of the target(s) through a detection area. Attachment unit(s) responsive to the control circuitry are provided for attaching the one or more reservoirs to the blood or lymph vessel.

Active tremor control in surgical instruments

Abstract: Described embodiments include a handheld or hand operated surgical instrument. The instrument includes an elongated member having a longitudinal axis and a handle portion. The instrument includes a working tip coupled to the elongated member. The instrument includes a sensor configured to detect a user-imparted hand tremble motion. The instrument includes a flexible beam element of the elongated member located in-between the handle portion and the working tip, and configured to reversibly bend, extend, or rotate with respect to the longitudinal axis. The instrument includes an actuator physically coupled to the flexible beam element and configured to reversibly bend, extend, or rotate the flexible beam element with respect to the longitudinal axis. The instrument includes a controller configured to stabilize the working tip by activating the actuator in a manner responsive to the detected user-imparted hand tremble motion in at least one degree of freedom.

Surgical Stapling Apparatus

Abstract: A surgical stapling device particularly suited for endoscopic procedures is described The device includes a handle assembly and an elongated body extending distally from the handle assembly The distal end of the elongated body is adapted to engage a disposable loading unit A control rod having a proximal end operatively connected to the handle assembly includes a distal end extending through the elongated body A control rod locking member is provided to prevent movement of the control rod until the disposable loading unit is fully secured to the elongated body of the stapling device

Surgical stapling instrument with an articulatable end effector

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.

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

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.

Surgical instrument having recording capabilities

Abstract: A surgical instrument. The surgical instrument has an end effector and a trigger in communication with the end effector. The surgical instrument also has a first sensor and an externally accessible memory device in communication with the first sensor. The first sensor has an output that represents a first condition of either the trigger or the end effector. The memory device is configured to record the output of the first sensor. In various embodiments, memory device may include an output port and/or a removable storage medium.
