Abstract
The present disclosure provides for a microwave forceps for sealing tissue. The forceps includes a shaft member having an end effector assembly disposed at a distal end thereof. The end effector assembly includes opposing jaw members movable from a first position in spaced relation relative to one another to at least one subsequent position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members includes a sealing surface, wherein one of the sealing surfaces includes one or more microwave antennas coupled to a source of microwave energy.
Claims20
A microwave forceps for sealing tissue, comprising:
- at least one shaft member having an end effector assembly disposed at a distal end thereof the end effector assembly including opposing jaw members movable from a first position in spaced relation relative to one another to at least one subsequent position wherein the jaw members cooperate to grasp tissue therebetween, each of the jaw members including a sealing surface, at least one of the sealing surfaces including a microwave antenna assembly coupled to a source of microwave energy.
A microwave forceps for sealing tissue, comprising:
- at least one shaft member having an end effector assembly disposed at a distal end thereof, the end effector assembly including a first and second opposing jaw members movable from a first position in spaced relation relative to one another to at least one subsequent position wherein the jaw members cooperate to grasp tissue therebetween, each of the jaw members including a seating surface;
- a microwave antenna assembly coupled to a microwave energy source, the microwave antenna assembly disposed on the sealing surface of the first jaw member, wherein the microwave antenna assembly includes:
- a grounding member coupled to a ground reference of the microwave energy source and disposed within the first jaw member;
- a dielectric substrate disposed on the grounding member;
- and
- a patch antenna coupled to an active element of the microwave energy source and disposed on the dielectric substrate.
A microwave forceps for sealing tissue, comprising:
- at least one shaft member having an end effector assembly disposed at a distal end thereof, the end effector assembly including a first and second opposing jaw members movable from a first position in spaced relation relative to one another to at least one subsequent position wherein the jaw members cooperate to grasp tissue therebetween, each of the jaw members including a sealing surface;
- a microwave antenna assembly coupled to a microwave energy source, the microwave antenna assembly disposed on the sealing surface of the first jaw member, wherein the microwave antenna assembly includes:
- a slot antenna having a substantially rectangular slot defined therethrough, the rectangular slot having a first longitudinal side coupled to a ground reference of the microwave energy source and a second longitudinal side coupled to an active element of the microwave energy source.
A microwave forceps for sealing tissue, comprising:
- at least one shaft member having an end effector assembly disposed at a distal end thereof, the end effector assembly including opposing jaw members movable from a first position in spaced relation relative to one another to at least one subsequent position wherein the jaw members cooperate to grasp tissue therebetween, each of the jaw members including a sealing surface, at least one of the sealing surfaces including a microwave antenna assembly coupled to a source of microwave energy, wherein the microwave antenna assembly is configured to operate in a therapeutic mode to deliver microwave energy to tissue and in a detection mode to measure at least one tissue property.
