The present disclosure relates to a dissecting tip for use in a surgical stapler or instrument.

A medical device includes an elongate member configured to be at least partially disposed within a body of a patient. The elongate member has an outer surface. The outer surface of the elongate member has a first ridge and a second ridge.

A stapling system including a housing that has a first rotatable disk configured to transmit a first operative motion and a second rotatable disk configured to transmit a second operative motion is disclosed herein. The second rotatable disk is operable independently of said first rotatable disk. The stapling system further includes an end effector, an elongate rigid shaft, and a drive system. The drive system is responsive to the first operative motion from the first rotatable disk to perform a closing motion of the end effector and responsive to the second operative motion from the second rotatable disk to perform a firing stroke. A control system is configured to assure that the closing motion and the firing stroke are separate and distinct, wherein the control system prevents the firing stroke from occurring prior to the completion of the closing motion.

Disclosed is a surgical system, comprising an end effector configurable between an open state and a clamped state. The end effector comprises a first jaw and a second jaw moveable relative to the first jaw. The surgical system further comprises a drive system, comprising a motor and a drive assembly movable by the motor to effect a tissue-treatment motion at the end effector. The surgical system further comprises a motor control system comprising motor control electronics. The motor control system is configured to transmit a motor drive signal that causes the motor to move the drive assembly to effect the tissue-treatment motion at the end effector and control the motor control electronics to modify the tissue-treatment motion independent of the motor drive signal.

A surgical instrument including an end effector that has a selectively reciprocatable implement movably supported therein. The implement is selectively advanceable in a distal direction upon application of a rotary actuation motion thereto and retractable in a proximal direction upon application of a rotary retraction motion thereto. An elongate shaft assembly is coupled to the end effector and is configured to transmit the rotary actuation motion and rotary retraction motion to the reciprocatable implement from a robotic system that is configured to generate the rotary actuation motion and said rotary retraction motion.

A surgical instrument for use with a robotic surgical system including a drive assembly is disclosed. The surgical instrument comprises a first transmission including a first drive element configured to be driven by the drive assembly to apply a first control motion to an end effector. The surgical instrument also comprises a second transmission including a second drive element configured to be driven by the drive assembly to apply a second control motion to the end effector when the second drive element is in a first position and to apply a third control motion to the end effector when the second drive element is in a second position. The second transmission includes a shifting element that is configured to selectively switch the second drive element between the first position and the second position. The first transmission and the second transmission are operable independent of each other.

An implant insertion device is adapted for use with a shape memory implant. The shape memory implant includes a bridge interconnecting first, second, and third legs. The shape memory implant is movable between a first shape in which at least the first leg is substantially non-parallel and a second shape in which at least the first leg is substantially parallel. The implant insertion device engages the shape memory implant to maintain the shape memory implant in its second shape until the delivery of the shape memory implant into tissue or bone.
