Disclosed is a surgical instrument comprising an end effector with energy sensitive resistance elements.

A surgical instrument assembly is disclosed. The surgical instrument assembly comprises a shaft, an articulation region, and an end effector attached to the shaft by way of the articulation region, wherein the end effector is configured to be articulated relative to the shaft. The shaft comprises an outer housing, an inner spine positioned with the outer housing, and a core member positioned within the inner spine. The core member comprises a distal end attached to a component the end effector and a proximal end attached to the proximal housing, wherein the core member comprises a material different than a material of the inner spine, and wherein the core member defines a maximum system stretch of the inner spine.

A surgical system for osteosynthesis of femoral fractures, individual parts of such system, and a related surgical procedure is provided. Two different osteosynthesis methods are combined: the intramedullary hip screw for hip fractures and the retrograde femoral nail for femoral shaft fractures. The system includes a new jig for the insertion of the retrograde intramedullary nail and the femoral neck screw. The surgical system makes it possible to osteosynthesize obese patients with trochanteric hip fractures in a safer and improved controlled surgery with the aim of reducing complications to this type of surgery.

A surgical instrument assembly is disclosed. The surgical instrument assembly comprises a shaft, an end effector, and a drive member configured to actuate a function of the end effector. The surgical instrument assembly further comprises an articulation member configured to be actuated to articulate the end effector and an articulation region, wherein the articulation member is configured to articulate the end effector relative to the shaft by way of the articulation region, wherein the drive member extends through the shaft, the articulation region, and the end effector. The articulation region comprises an articulation support pivot positioned within the articulation region, wherein the articulation member is coupled to the articulation support pivot, wherein the articulation member is actuatable to rotate the articulation support pivot, and wherein the drive member extends through the articulation support pivot.

Disclosed is a surgical staple for a combination energy stapler surgical instrument. The staple includes a crown defining a base, first and second deformable legs extending from the each end of the base and an electrically insulative material disposed on at least a portion of the base.

A surgical instrument comprising an elongate shaft, an articulation joint, and a channel extending from the elongate shaft at a point distal to the articulation joint is disclosed. The surgical instrument further comprises an end effector assembly comprising an anvil and a cartridge pivotally coupled to the anvil. The anvil is configured to move relative to the cartridge between an open position and a closed position. The cartridge is configured to be replaceably seated in the channel A drive screw is mounted in the channel before the cartridge is seated therein, and a firing member is positioned on the drive screw before the cartridge is seated in the channel. The firing member is configured to translate through the end effector assembly during a firing stroke.

Disclosed is a method of detecting a short circuit in the jaws of an end effector of a surgical instrument. The method includes applying a sub-therapeutic electrical signal to an electrode located in the jaws of the end effector. The sub-therapeutic electrical signal comprises a sequence of exploratory waveforms comprising pulsed current and voltage waveforms. The method includes detecting a shorted electrode when a measured electrical parameter in the jaws of the end effector is less than a predetermined value and modifying electrical current applied to the shorted electrode by the RF generator.

Disclosed are surgical instruments configured to control therapeutic energy application to tissue based on cartridge and tissue parameters.

A surgical instrument comprising a translatable closing bar and a translatable firing bar is disclosed.

Disclosed is a surgical system for tissue treatment using therapeutic energy and stapling.
