    Abstract: A surgical instrument includes a housing, an inner shaft coupled to and extending distally from the housing, an end effector assembly disposed at a distal end of the inner shaft, an outer sheath that is fixed to the housing, extends distally from the housing, and is disposed about the inner shaft, and an insulative sleeve. The insulative sleeve is positioned between the inner shaft and the outer sheath. The insulative sleeve is movable relative to the inner shaft and the outer sheath between a storage position, wherein the insulative sleeve is positioned proximally of the end effector assembly, and a deployed position, wherein the insulative sleeve substantially surrounds the end effector assembly.

    Abstract: An endoscopic forceps includes a housing having a shaft attached thereto that supports a pair of jaws disposed at a distal end thereof. A drive assembly having a drive shaft with a proximal end is operable to move the jaws relative to one another from an open to closed positions. A knife assembly is operable to advance a knife through tissue disposed between the jaws and includes a flange disposed thereon. A knife lockout is included that has a flange configured to engage the proximal end of the drive shaft and a lockout arm configured to engage the flange of the knife assembly to prevent movement thereof. Movement of the jaws to the closed position causes the proximal end of the drive shaft to engage the flange on the lockout which causes the lockout arm to disengage the flange on the knife assembly to permit advancement of the knife.

    Abstract: An endoscopic instrument is provided and includes a housing including an elongated shaft assembly extending distally therefrom. The elongated shaft assembly includes inner and outer shaft members. The inner and outer shaft members are removably coupled to the housing and the outer shaft member is movable with respect to the inner shaft member. An end effector is operably supported at the distal end of the outer shaft member and includes a pair of jaw members configured for treating tissue. A bushing operably couples to the inner and outer shaft members of the shaft assembly and selectively and releasably couples to the housing. The bushing includes one or more mechanical interfaces configured to engage one or more slots defined through the inner shaft member and one or more slots defined through the outer shaft member to release the inner and outer shaft members from the housing.

    Abstract: A sphincter assist device includes a plurality of interconnected and adjacent links which define a ring. Each link includes a body section and a latch cam. The body section includes a first set of side beams and a first set of snap arms. The latch cam includes a post extending from the body section and a cam disposed at an end portion of the post. The cam is engagable with the first set of snap arms of an adjacent link. Translation of the cam displaces the first set of snap arms and the first set of side beams to transition the sphincter assist device between open and closed configurations. The first set of snap arms, in combination with the first set of side beams, exert a positive non-linear force profile on the cam, thus defining a non-linear force profile of the sphincter assist device between the open and closed configurations.

    Abstract: A surgical instrument includes a handle movable between first and second positions for transitioning an end effector assembly between states and to a third position for returning the handle. A latch arm coupled to the handle includes one or more engagement members. A latch block defines a guide track having a latching path configured to guide the engagement member(s) therealong, an engagement portion configured to engage the engagement member(s) to latch the handle in the second position, and a return path configured to guide the engagement member(s) therealong. A first step interdisposed between the latching path and engagement portion guides the engagement member(s) into engagement with the engagement portion and inhibits the engagement member(s) from returning along the latching path. A second step interdisposed between the engagement portion and the return path guides the engagement member(s) along the return path and inhibits the engagement member(s) from re-engaging the engagement portion.

    Abstract: A surgical instrument includes a first actuation assembly coupled to a first component and movable from a first position to a second position to actuate the first component. A biasing member coupled to the first actuation assembly is configured to bias the first actuation assembly towards the first position. A second actuation assembly is coupled to a second component and is selectively actuatable to actuate the second component. The second actuation assembly is coupled to the first actuation assembly such that actuation of the second actuation assembly effects movement of the first actuating assembly from the first position towards the second position. A linkage assembly is configured to reduce the bias applied to the first actuation assembly when the second actuation assembly effects movement of the first actuation assembly.
