  • Patent number: 10568629
    Abstract: A stapling system comprising an anvil, a channel, a firing member, a lock recess, a replaceable staple cartridge, and an articulation joint is disclosed. The firing member comprises a lock shoulder and a coupling portion configured to couple the anvil and the channel. The replaceable staple cartridge comprises staples and a sled movable between a proximal unfired position and a distal fired position during a firing stroke of the firing member to eject the staples. The lock shoulder is engageable with the lock recess when the sled is not in the proximal unfired position to block the firing stroke from being performed. The sled prevents engagement between the lock shoulder and the lock recess when the sled is in the proximal unfired position to permit the firing stroke to be performed. The staple cartridge is attached to the stapling system distal to the articulation joint.

  • Patent number: 10569071
    Abstract: Various exemplary devices and methods are provided for performing surgical procedures. In general, one or more adjuncts can be used in conjunction with surgical instruments. The adjunct(s) can have medicant(s) thereon and/or therein. The medicant(s) can vary depending on the desired effect of the medicant(s) on surrounding tissue. As a non-limiting example, medicant(s) can be provided to influence hemostasis, inflammation, macrophages, and/or fibroblasts. When used in conjunction with a surgical stapler, the adjunct(s) can be disposed between and/or on jaws of the stapler, incorporated into a staple cartridge disposed in the jaws, or otherwise placed in proximity to the staples. When staples are deployed, the adjunct(s) can remain at the treatment site with the staples.

  • Patent number: 10568566
    Abstract: Biomarkers are collected and used to determine biological propensities of a patient, to determine the efficacy of medical devices, to select and administer therapeutic agents, to select medical devices, to make adjustments to medical devices, and/or to adjust surgical techniques. An apparatus includes a port to draw a biological fluid (e.g., a mist) from a surgical site. The apparatus includes a sensor having a cantilevered beam. The beam includes substances selected to attract certain biomarkers as the fluid is communicated across the beam. The same apparatus or another apparatus is used to administer a therapeutic agent based at least in part on collected biomarker data. The therapeutic agent delivery apparatus may include a device that is also used to create a wound at a surgical site. For instance, a harmonic surgical instrument may be used to both collect biomarkers and administer a therapeutic agent (e.g., gene therapy using sonoporation).

  • Patent number: 10568624
    Abstract: A surgical instrument with first and second jaws that are pivotally supported relative to each other for pivotal travel about a fixed pivot axis between open and closed positions. A firing member is movably supported for selective axial travel between starting and ending positions within at least one the jaws and is configured to engage both jaws when the jaws are in a closed position. A firing system operably interfaces with the firing member to selectively axially move the firing member between the starting and ending positions and a closure system that operably interfaces with at least one of the jaws to move the jaw between the open and closed positions without actuating the firing system.

  • Publication number: 20200054320
    Abstract: A method for operating a surgical instrument. The method includes linking a second drive member to a first drive member such that the second drive member moves with the first drive member. The method further includes applying first control motions to the first drive member to cause the second drive member to apply actuation motions to a surgical end effector. The method also includes discontinuing application of the first control motions to the first drive member and de-linking the second drive member from the first drive member such that the second drive member is locked in place by a locking system. The method also includes re-applying control motions to the first drive member.

  • Publication number: 20200054321
    Abstract: A surgical instrument that includes a first jaw and a second jaw that are movable between a closed position and an open position. An axially movable closure member is supported relative to the jaws to apply closing and opening motions thereto. A closure actuator operably interfaces with the closure member and is movable from an unactuated position corresponding to the open position in a closure direction during a closure procedure. A first control system is configured to apply an opening control motion to the closure actuator to return the closure actuator to the unactuated position upon completion of the closure procedure. A second control system is configured to apply a variable closure force to the closure member as the closure actuator is moved in the closure direction.
