发明名称 END EFFECTOR WITH REDUNDANT CLOSING MECHANISMS
摘要 End effectors with redundant closing mechanisms, and related tools and methods are disclosed. The disclosed end effectors may be particularly beneficial when used for minimally invasive surgery. An example surgical tool comprises an elongate shaft having a proximal end and a distal end, a tool body disposed at the distal end of the shaft, a jaw movable relative to the tool body between a clamped configuration and an open configuration, a first actuation mechanism coupled with the jaw and operable to vary the position of the jaw relative to the tool body between the clamped configuration and the open configuration, and a second actuation mechanism coupled with the jaw. The second actuation mechanism has a first configuration where the jaw is held in the clamped configuration and a second configuration where the position of the jaw relative to the tool body is unconstrained by the second actuation mechanism.

主权项 1. A minimally invasive surgical method comprising: introducing a jaw of a tool to an internal surgical site within a patient through a minimally invasive aperture or natural orifice, the jaw being configured to open and close on a distal side of a jaw pivot point; manipulating tissue at the internal surgical site with a grasping force by articulating the jaw with a first actuation mechanism, the first actuation mechanism extending along a shaft from outside the patient to the jaw; and treating a target tissue at the internal surgical site using a clamping force by applying a force to the jaw of the tool at a proximal side of the jaw pivot point with a second actuation mechanism, the second actuation mechanism extending along the shaft from outside the patient to the jaw, the clamping force being greater than the grasping force.
