A forceps includes an end effector assembly having first and second jaw members movable between a spaced-apart position and an approximated position for grasping tissue therebetween. A knife assembly having a cutting blade disposed at a distal end thereof is also provided. The knife assembly is translatable relative to the end effector assembly between a retracted position and an extended position, wherein the cutting blade extends between the jaw members to cut tissue grasped therebetween. The knife assembly includes a proximal component and a first distal component that includes the cutting blade. The proximal and first distal components are removably coupled to one another to facilitate replacement of the first distal component. Methods of preparing such forceps for reuse are also provided.

An electrosurgical device having first and second poles; blade electrode with a metal shim having two opposing faces and one or more facets, a nonconductive coating which covers at least the faces and a portion of the facets of the metal shim, while a distal portion of the one or more facets remains uncovered by the nonconductive coating; a lateral electrode comprised of a broad shim having one or more conductive faces and is placed parallel to the blade electrode so that at least one of the one or more conductive faces is exposed and a distal end of the blade electrode protrudes from the lateral electrode; the lateral electrode is fixed stationary relative to the blade electrode; the nonconductive coating insulates the blade electrode from the lateral electrode; and the first pole is connected to the blade electrode and the second pole is connected to the lateral electrode.

Forceps that include a hand piece, a jaw assembly connected to the hand piece, and a web. The jaw assembly is moveable between an open position and a closed position. The web is adapted to block an anatomical feature from extending beyond a proximal end of a gripping section of the jaw assembly. The web remains generally stationary relative to the handpiece when the jaw assembly is moved between an open position and a closed position.

Various embodiments of tool assemblies are provided having at least one rotary input coupling and at least one linear input coupling for allowing either a rotary output or a linear output (e.g., from a tool driver on a surgical robot) to activate at least one mechanism of the tool assembly. For example, mechanisms of the tool assembly can include a clamping assembly, a firing assembly, an articulation assembly, and a roll assembly. The clamping assembly can open and close jaws of an end effector, the firing assembly can translate a knife assembly through the end effector to fire staples and cut tissue, the articulation assembly can articulate the end effector, and the roll assembly can rotate the elongate shaft and/or the end effector.

A biopsy forceps device includes a tension member and an end effector including first and second jaws movable between an open configuration, in which the jaws are separated from one another to receive target tissue therebetween, and a closed configuration, in which cutting edges of the jaws are moved toward one another to cut a portion of the target tissue. The jaws define a tissue receiving space therebetween to house the cut tissue. The jaws are pivotable relative to one another, each of the jaws including a serrated cutting edge extending therealong, the end effector further including a tension member attachment including a proximal end coupled to the tension member. The attachment is movably coupled to the jaws so that distal movement of the attachment moves the jaws to the open configuration while proximal movement thereof moves the jaws to the closed configuration.
