摘要： 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. For example, a surgeon can actuate an actuation mechanism on the proximal end of the shaft to mate one of the end effectors to the distal end of the shaft without assistance from other tools and devices. After use of the end effector, the end effector can be released and another end effector can be remotely attached to the distal end of the shaft.

摘要： A surgical stapling instrument including an actuator configured to be retracted relative to the distal end of the disposable loading unit and rotate an anvil between an open position and a closed position. The actuator can include a cam, where the cam can include an arcuate profile having an apex configured to be in contact with the anvil when the anvil is in a closed position. In at least one such embodiment, the anvil can apply a clamping force to the soft tissue prior to the staples being deployed to prevent, or at least inhibit, soft tissue from flowing, or ‘milking’, out of the distal end of the disposable loading unit. In various embodiments, a surgical stapling instrument can include a disposable loading unit having an anvil which can be moved between open, closed, and/or collapsed positions to facilitate the insertion of the disposable loading unit through a trocar.

摘要： 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.
