Abstract
Certain aspects relate to systems, devices and techniques for vessel sealing and cutting. In particular, an instrument is provided that is capable of performing multiple functions, including sealing and cutting. The instrument can be robotically controlled, and can include a shaft, a multi-DOF wrist, and an end effector. The end effector is capable of generating and delivering heat via different energy modalities to perform the various functions at different temperatures.
Claims14
A multi-functional medical instrument comprising:
- a shaft;
- a wrist coupled to the shaft, wherein the wrist is movable in at least two degrees of freedom;
- and
- an end effector configured to generate heat to perform sealing or cutting, the end effector comprising:
- a non-bladed first jaw comprising a first pad;
- a non-bladed second jaw comprising a second pad;
- and
- a conductive line disposed adjacent to the first pad and forming a loop substantially around a perimeter of the first pad and adjacent to the second pad and forming a loop substantially around a perimeter of the second pad, wherein the conductive line is coated with a ferromagnetic coating.
A medical system comprising:
- a robotic arm;
- an instrument coupled to the robotic arm, the instrument comprising:
- a shaft;
- a wrist coupled to the shaft;
- and
- an end effector configured to generate heat to perform sealing and cutting functions, the end effector comprising:
- a non-bladed first jaw comprising a first pad;
- a non-bladed second jaw comprising a second pad;
- and
- a conductive line disposed adjacent to the first pad and forming a loop substantially around a perimeter of the first pad, wherein the conductive line is coated with an intermittent ferromagnetic coating;
- and
- a processor configured to modulate a temperature of the end effector to enable two different functions to be performed.
A medical method comprising:
- operating a multi-functional instrument to perform a heat-generating function, wherein the instrument comprises a shaft, a wrist having movement in two or more directions, and an end effector, the end effector comprising:
- a non-bladed first jaw comprising a first pad;
- a non-bladed second jaw comprising a second pad;
- and
- at least one conductive line for performing the first heat-generating function disposed adjacent to the first and second pads and forming a loop substantially around a perimeter of the first and second pads;
- modifying the instrument to perform a second heat-generating function that is different from the first heat-generating function, wherein the second heat-generating function is performed by the conductive line.
