Publication number: 20180103954Abstract: In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.Type: ApplicationFiled: October 25, 2017Publication date: April 19, 2018Inventors: William B.

Patent number: 9801648Abstract: A surgical instrument that may include a housing, a transducer engaged with the housing which can produce vibrations, and an end-effector engaged with the transducer. The surgical instrument can further include an adjustable sheath extending from the housing where the sheath is movable relative to the distal tip of the end-effector and where the distance between the distal tip of the sheath and the distal tip of the end-effector can be set such that the sheath can act as a depth stop. The sheath can be adjusted such that, when the distal tip of the sheath contacts the tissue or bone being incised, the surgeon can determine that the appropriate depth of the incision has been reached. In other embodiments, the end-effector can be moved with respect to the sheath in order to adjust the distance between the distal tip of the end-effector and the distal tip of the sheath.Type: GrantFiled: October 28, 2014Date of Patent: October 31, 2017Assignee: Ethicon LLCInventors: Kevin L.

Publication number: 20170258483Abstract: Methods and devices are provided for performing various procedures using interchangeable end effectors. In general, the methods and devices allow a surgeon to remotely and selectively attach various interchangeable surgical end effectors to a shaft located within a patient's body, thus allowing the surgeon to perform various procedures without the need to remove the shaft from the patient's body. In an exemplary embodiment, multiple end effectors can be introduced into a body cavity. The end effectors can be disassociated or separate from one another such that they float within the body cavity. A distal end of a shaft can be positioned within the body cavity and it can be used to selectively engage one of the end effectors. In particular, the device can be configured to allow each end effector to be remotely attached and detached from the distal end of the shaft.Type: ApplicationFiled: May 25, 2017Publication date: September 14, 2017Inventors: Jonathan A. Coe, James W. Voegele, Gary L. Long, Andrew M. Zwolinski, Kyle P. Moore, Robert P. Gill
