An ultrasonic surgical system is disclosed comprising a surgical instrument and a wrench assembly. The surgical instrument comprises a handle assembly and a body member pivotably coupled to the handle assembly. The handle assembly comprises a first finger grip, an ultrasonic blade, and a waveguide extending proximally from the ultrasonic blade. The body member comprises a second finger grip, a clamp arm movable relative to the ultrasonic blade to capture tissue therebetween, a first body surface defined on a first side of the body member, and a second body surface defined on a second side of the body member. The wrench assembly comprises a wrench and an adapter operably coupled to the wrench. The adapter comprises a first wrench surface configured to engage the first body surface and a second wrench surface configured to engage the second body surface.

Ultrasonic device for cutting and coagulating

Circular stapling instruments and anvil assemblies. The anvil assemblies may have collapsible anvil support members that may be inserted through an opening in a patient and then expanded to be attached to an anvil plate assembly that has a staple-forming surface thereon. The anvil support member is attachable to the anvil plate assembly in such a way that when the anvil assembly is coupled to the stapling head of a circular stapler, the staple-forming surface is in substantial registry with the staples supported in the stapling head. A variety of different anvil support members and anvil plate assemblies are disclosed.

Anvil assemblies for circular staplers

A surgical instrument can include an anvil and, in addition, a staple cartridge support configured to support a staple cartridge. In various embodiments, the jaw can be moved toward the staple cartridge to deform staples contained within the staple cartridge. The anvil can be configured to be translated and/or rotated as the anvil is moved toward the staple cartridge. In certain embodiments, the anvil can be configured to float and adjust such that the anvil is moved downwardly in a level manner.

Apparatus and method to permit selective cutting and coagulation required in fine and delicate surgical procedures. The apparatus includes two body members having proximal ends and distal ends with jaw members located adjacent the body member's distal ends. The body members are joined at a pivot located adjacent to the first and second jaw members joining the first and second body members where the body members' rotation about the pivot defines a plane of rotation. The scissors are adapted for selective application of energy to at least one jaw member by a switch located in the plane of rotation.

A surgical instrument includes an anvil selectively coupleable to a stapling head assembly and a trigger operable to fire staples into tissue compressed between the anvil and the stapling head assembly. In some versions, a lockout member may engage a securing feature to prevent actuation of the anvil relative to the stapling head assembly. For instance, a tab may engage a slot on an actuator, a screen door lock may provide frictional resistance or engage teeth on the actuator, a door may actuate into engagement with one or more recesses, geared teeth may mesh with teeth on the actuator, the lockout member may include a ratcheting assembly to engage actuator, and/or a push button may actuate into a recess while disengaging the lockout member. Alternatively, in some versions, the trigger actuation assembly may be disengaged prior to firing. An anvil position indicator may restrict engagement of the trigger actuation assembly.

Feature to reengage safety switch of tissue stapler

A surgical stapler configured to clamp, staple, and cut tissue is disclosed. The surgical stapler comprises a housing, a shaft, a staple cartridge, an expandable anvil, and a distal head portion. The shaft extends from the housing and comprises three concentric actuators. The three concentric actuators are operable independently of each other. The three concentric actuators are actuatable relative to the housing and are configured to perform three separate and distinct end effector functions. The staple cartridge comprises a unitary cartridge body. The distal head portion is configured to rotate relative to the shaft. One of the separate and distinct end effector functions comprises rotating the distal head portion to expand the anvil.

A surgical stapling system for stapling patient tissue is disclosed. The stapling system comprises a handle, a shaft, an end effector, and a firing system. The end effector comprises an anvil, a staple cartridge, an implantable layer, and anchors. The staple cartridge comprises a cartridge body comprising a deck surface including a plurality of staple cavities. The staple cartridge further comprises a plurality of staples and a longitudinal slot. The staples comprise a first longitudinal row of staples having a first unformed height and a second longitudinal row of staples having a second unformed height. The firing system comprises a tissue cutting edge and is configured to translate within the longitudinal slot such that the anchors are progressively transected by the tissue cutting edge to progressively release the implantable layer from the cartridge body while the staples are progressively ejected from the staple cavities to staple the patient tissue.

Surgical stapling system comprising an end effector including an implantable layer

A surgical instrument includes a handle assembly having a trigger operable to fire a staple driver to staple tissue. The instrument includes a pointed rod to which an anvil may be coupled. An anvil detection feature is included to determine when the anvil is coupled to the rod. In some versions, the anvil detection feature comprises a translatable rod that inhibits a lockout feature from disengaging. In other versions, an anvil sensing tube is disposed about the pointed rod and interferes with actuation of the trigger in a first position. A recess in the tube permits trigger to actuate when the anvil sensing tube is in the second position. Alternatively, a resilient tab is coupled to the pointed rod and resists actuation of the staple driver. A trigger lockout assembly may include a spring-loaded button that 'pops' out when a push rod is actuated, thereby freeing a pivotable lockout feature.

Tissue stapler anvil feature to prevent premature jaw opening

A surgical stapling system for stapling patient tissue is disclosed. The surgical stapling system comprises an end effector and an actuation system. The end effector comprises a first jaw, a movable jaw operably attached to the first jaw, and a plurality of staples. The actuation system is configured to actuate the movable jaw toward the first jaw to clamp the patient tissue against the first jaw while the movable jaw progressively drives the staples against the first jaw to staple the patient tissue.

Stapling system including an actuation system

An end effector for stapling patient tissue is disclosed. The end effector comprises a frame comprising a proximal end and a distal end, a plurality of staples, a firing system configured to implant the staples into the patient tissue, an implantable layer comprising a tissue-contacting surface and a support surface, and an array of securement members extending above and below the support surface of the implantable layer. The securement members are detached from the frame concurrently with the firing system being actuated to implant the staples.
