Abstract: Systems, devices, and methods for controlling cooperative surgical instruments are provided. Various aspects of the present disclosure provide for coordinated operation of surgical instruments accessing a common body cavity of a patient from different approaches to achieve a common surgical purpose. For example, various methods, devices, and systems disclosed herein can enable the coordinated treatment of surgical tissue by disparate minimally invasive surgical systems that approach the tissue from varying anatomical spaces and operate in concert with one another to effect a desired surgical treatment.

Abstract: A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.

Abstract: A fastener cartridge can include, one, a cartridge body comprising a deck and a plurality of fastener cavities and, two, a plurality of fasteners positioned in the fastener cavities. The cartridge body can further comprise extensions extending from the deck having different sizes and/or configurations. The extensions can control the flow of tissue relative to the deck and/or support the fasteners as they are ejected from the fastener cavities.

Abstract: A surgical instrument. The surgical instrument includes an elongated channel configured to support a staple cartridge, an anvil pivotably connected to the elongated channel, a knife mechanically coupled to the staple cartridge, an electric motor and a control circuit electrically connected to the electric motor. The control circuit is configured to change a firing motion of the surgical instrument based on a combination of events.

Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Abstract: A bulk processing meat cutlet tenderizing machine is provided with multiple sets of roller cutters between which a meat cutlet is tenderized. The roller cutters of each set are arranged in parallel pairs with rotary tenderizing knives mounted on each roller cutter. The second set of roller cutters are vertically spaced with respect to the roller cutters of the first set to permit a meat cutlet to be engaged and perforated simultaneously by the rotary knives of both first and second sets as the meat cutlet advances through the roller cutter pairs. The cutlets are inverted automatically after passing through a first array of roller cutters. The cutlets then undergo further perforation and enlargement in successive cutter stations.

Abstract: A meat cutlet tenderizing machine having first and second sets of coacting roller cutters between which a meat cutlet is fed is disclosed. The coacting roller cutters of each set are arranged in parallel pairs with rotary tenderizing knives mounted in axially spaced relation on each roller cutter. The second set of roller cutters are vertically spaced with respect to the roller cutters of the first set to permit a meat cutlet to be engaged and perforated simultaneously by the rotary tenderizing knives of both first and second sets as the meat cutlet advances through the coacting roller cutter pairs. The coacting roller cutters are driven by a chain and sprocket assembly in which the drive sprocket coupled to the roller cutters of the second set has a greater number of sprocket teeth than the drive sprocket coupled to the roller cutters of the first set thereby causing the rotary tenderizing knives of the second set to rotate at a faster rate relative to the rotary tenderizing knives of the first set.
