Abstract
An end effector of an electrosurgical device may include a first body, a first electrode on the left side of the first body, and a second electrode on the right side of the first body. The first and second electrodes may be configured to receive electrosurgical energy to treat tissue in a target treatment zone. The end effector may also include a fluid aspiration port in fluid communication with a fluid path. The fluid aspiration port may be configured to remove a material from the target treatment zone.
Claims27
An electrosurgical instrument comprising:
- an end effector comprising:
- a first body;
- a first electrode on the left side of the first body;
- a second electrode on the right side of the first body, wherein the first and second electrodes are configured to receive electrosurgical energy to treat tissue in a target treatment zone;
- and
- a fluid aspiration port in fluid communication with a fluid path, wherein the fluid aspiration port is configured to remove a material from the target treatment zone.
An electrosurgical instrument comprising:
- a shaft;
- and
- a mesh end effector comprising:
- at least one insulated weft wire;
- and
- a plurality of insulated warp wires,
- wherein each of the plurality of insulated warp wires is alternately woven above and below the at least one insulated weft wire,
- wherein each of the plurality of insulated warp wires defines at least one high point where each of the plurality of insulated warp wires is woven above the at least one insulated weft wire,
- wherein the at least one high point in each of the plurality of insulated warp wires exposes a non-insulated conductive site to provide electrosurgical energy to a target tissue.
A method comprising:
- providing a plurality of layers, wherein each of the plurality of layers includes a signal wire disposed in a top portion of each of the plurality of layers and a plurality of dot wires extending down from the signal wire, wherein the signal wire is configured to deliver electrosurgical energy to the plurality of dot wires;
- arranging the plurality of layers;
- overmolding a molding material onto the arranged plurality of layers;
- and
- cutting a bottom portion of the overmolded plurality of layers to expose a cut end of each of the plurality of dot wires, wherein the overmolded plurality of layers define a first bottom surface that is formed after the cutting, wherein the first bottom surface of the overmolded plurality of layers forms an array of the cut ends of the plurality of dot wires.
