Embodiments include an end effector including an anvil, the anvil having an anvil face, an anvil blade channel defined by the anvil face, a first pocket row of first row staple pockets, a second pocket row of second row staple pockets, a third pocket row of third row staple pockets, a fourth pocket row of fourth row staple pockets, a fifth pocket row of fifth row staple pockets, a sixth pocket row of sixth row staple pockets, a cartridge having a a cartridge face defining a cartridge blade channel, the cartridge being configured to retain a plurality of staples, and a blade, the blade having a cutting edge, where the blade is movable from a first position at a distal end of the cartridge to a second position at a proximal end of the cartridge.

A surgical instrument includes a housing having a barrel defining an axis and a fixed handle extending from the barrel. The barrel includes at least one elongated indentation and the fixed handle defines a waist. A shaft extends from the barrel along the axis and couple to an end effector at a distal end thereof. A movable handle coupled to the housing is configured to manipulate the end effector. The movable handle includes a proximal leg, a distal tail, an arcuate segment defining a finger-retaining area, and a proximal foot. A deployable member is slidably disposed within the shaft. A trigger coupled to the housing is configured to deploy the deployable member. The trigger defines a saddle portion. The housing, movable handle, and trigger are configured to facilitate operable grasping by a hand of a user in at least first and second different grasping configurations.

Various embodiments for sustained drug delivery using a needle array are disclosed. A medical instrument and a method associated therewith are described for delivering drugs into tonsillar and other tissue as a way of treating tonsillar hypertrophy or inflammation, as an alternative to tonsillectomy and adenoidectomy (T&A) procedures. In some embodiments, a tonsil-accessible medical instrument is described as including a needle head having needles, or microneedles, disposed therein and capable of introducing a compound, such as a steroid, into tissue. The medical instruments enables for the delivery of various compounds, such as pharmaceuticals, for controlled and sustained release.

An end effector includes an anvil and a cartridge. The anvil can include a plurality of staple pockets positioned on an anvil face. The cartridge can be configured to retain a plurality of staples. Each of the plurality of staples includes a first staple leg, a second staple leg, and a crown connecting the first staple leg and the second staple leg, and each has an open staple configuration where the first staple leg and the second staple leg are generally perpendicular to a longitudinal axis of the crown and a closed staple configuration where a first tip of the first staple leg is bent in a first direction away from the longitudinal axis of the crown, and a second tip of the second staple leg is bent in a second direction away from the longitudinal axis of the crown, the first direction being different than the second direction.

A method of surgery includes grasping tissue between tissue-contacting surfaces of first and second jaw members of an end effector assembly, supplying energy to at least one of the tissue-contacting surfaces to treat tissue grasped therebetween, and translating and/or manipulating the end effector assembly to cut tissue in a ripping fashion.
