A surgical tool can include an outer tube, an end effector, an inner tube, and a distal plug. The outer tube can extend along a longitudinal axis and the outer tube can include a pair of outer arms. The end effector can be connected to the outer arms. The inner tube can be located within the outer tube and can extend along the longitudinal axis. The inner tube can be connected to the end effector and the inner tube can be translatable along the outer tube to operate the end effector. The distal plug can be securable to the outer tube between the outer arms proximal of the end effector. The distal plug can include a wire routing bore extending therethrough.

A surgical tool can include a shaft, a pin, an end effector, and a translating member. The shaft can define a longitudinal axis. The pin can be located at a distal portion of the shaft. The end effector can be connected to the shaft. The translating member can be positioned laterally inward of the shaft. The translating member can include a track and the pin can extend into the track to limit translation of the translating member along the longitudinal axis with respect to the end effector.

An ultrasonic surgical instrument and method of limiting an ultrasonic blade temperature includes adjusting at least one power parameter of the ultrasonic energy in response to reaching a predetermined frequency parameter change threshold in the ultrasonic blade limiting the temperature of the ultrasonic blade to an upper temperature limit. The ultrasonic surgical instrument further includes an end effector having an ultrasonic blade, a jaw, and a controller. The jaw is movably positioned relative to the ultrasonic blade and configured to move between an open position and a closed position. The controller operatively connects to the ultrasonic blade and is configured to measure an ultrasonic frequency of the ultrasonic blade. The controller has a memory including a plurality of predetermined data correlations that correlate changes in measured ultrasonic frequency of the ultrasonic blade to a blade temperature of the ultrasonic blade.

A forceps includes a pair of shaft members, a pair of jaw members each including a distal body and a proximal flange, and a pair of electrode plates. The proximal flanges are engaged with the respective shaft members and pivotably coupled to each other such that pivoting the shaft members pivots the distal jaw bodies. The electrode plates each includes a tissue-contacting portion disposed on the distal body of the respective jaw member and a proximal extension portion extending at least partially through the proximal flange of the respective jaw member. The tissue-contacting portion and proximal extension portion of the first electrode plate are disposed in perpendicular planes relative to each other. Likewise, the tissue-contacting portion and proximal extension portion of the second electrode plate are disposed in perpendicular planes relative to each other.

A forceps having a first jaw and a second jaw, where at least one of the first and second jaws is capable of moving between an open position and a closed positions. The forceps including an inner shaft located within an outer shaft and extending along the longitudinal axis, and a drive bar coupled to and extending distally from the inner shaft. The drive bar including a pair of drive bar struts extending from a distal portion of the inner shaft and positioned laterally inward of at least one of first and second set of flanges of the first and second jaws. A drive pin is securable to the pair of drive bar struts and the drive bar is translatable within the outer shaft to translate the drive pin to move the first jaw and/or the second jaw between open and closed positions.

An electrosurgical forceps includes first and second shaft members and first and second jaw members extending distally from the respective first and second shaft members. A pivot couples the first and second shaft members with one another such that the first and second shaft members are movable relative to one another between a spaced-apart position and an approximated position to move the first and second jaw members relative to one another between an open position and a closed position. The jaw members are configured to facilitate tissue treatment, tissue division, and blunt tissue dissection.

Apparatus for performing a minimally-invasive procedure, the apparatus comprising: a shaft having a distal end and a proximal end; a monopolar knife assembly attached to the distal end of the shaft, the monopolar knife assembly comprising a knife; a handle attached to the proximal end of the shaft; wherein the shaft comprises a flexible portion and an articulating portion, wherein the flexible portion extends distally from the handle and the articulating portion extends distally from the flexible portion; wherein at least one articulation cable extends from the handle to the articulating portion, such that when tension is applied to the at least one articulation cable, the articulating portion deflects; wherein an actuation element extends through the shaft from the handle to the knife, such that when the actuation element is moved, the knife is moved; and wherein the actuation element transmits electrical power from the handle to the knife.

An ultrasonic surgical instrument and method of sealing tissue includes interrogating the tissue with an electrical signal and adjusting an electrical parameter of at least one of the ultrasonic energy or the RF energy in response to the tissue feedback to inhibit transecting the tissue. The ultrasonic surgical instrument has an end effector, a shaft assembly, a body, and a power controller. The power controller is operatively connected to the ultrasonic blade and the RF electrode and configured to direct activation of the ultrasonic blade or the RF electrode. The power controller is further configured to interrogate the tissue with the electrical signal via the ultrasonic blade or the RF electrode to provide a tissue feedback and adjust an electrical parameter of the ultrasonic energy or the RF energy in response to the tissue feedback to inhibit transecting the tissue.

A surgical instrument comprising a shaft and an end effector is disclosed. The end effector is releasably attachable to the shaft by a lock biased into a locked condition to hold the end effector to the shaft.

A bipolar-microscissor forceps assembly includes a forceps having a first forceps arm having a first forceps distal tip and a first forceps proximal end and a second forceps arm having a second forceps distal tip and a second forceps proximal end. The second forceps proximal end is connected to the first forceps proximal end. A microscissors is disposed between the first forceps arm and the second forceps arm. A kit with a plurality of microscissors releasably connected to the forceps is also provided.
