A cable includes a sheath, and a coating film covering a circumference of the sheath. The coating film adheres to the sheath. The static friction coefficient of a surface of the coating film is smaller than the static friction coefficient of a surface of the sheath. The adhesion strength between the sheath and the coating film is 0.30 MPa or more.

A method of manufacturing a surgical instrument that includes an energized feature operable to apply ultrasonic energy or RF energy to tissue. The method includes forming at least one of a microscopic surface pattern or a nanoscopic surface roughness into a base surface of the energized feature to produce at least one recessed portion. The method also includes applying a hydrophobic coating that includes at least one of silicone, titanium nitride, chromium nitride, or titanium aluminum nitride to at least the recessed portion of the energized feature after forming at least one of the microscopic surface pattern or the nanoscopic surface roughness.

Provided is a surgical electrode in which an end portion capable of emitting a high frequency has a surface treatment film that includes a first coating and a second film in the order mentioned. The first coating is formed by contacting a surface treatment agent (X) with or over the entirety or a part of the surface of the end portion at least, which surface treatment agent (X) contains at least an amino group-containing compound, and the second film is formed by contacting a surface treatment agent (Y) with a part or the entirety of the surface of the first coating, which surface treatment agent (Y) contains: a silicone resin (A); a compound (B) containing a metal element selected from titanium, platinum, rhodium and palladium; and an aromatic hydrocarbon-based solvent (C), and satisfies: (I) the content of the silicone resin is in a range of 90% by mass to 99.9% by mass with respect to a total solid mass of the silicone resin and the compound; and (II) a ratio (B.sub.M/A.sub.M) of a mass (B.sub.M) of the compound to a mass (A.sub.M) of the silicone resin is in a range of 0.001 to 0.111.

An end effector assembly for use with an electrosurgical instrument is provided. The electrosurgical instrument includes a handle having a shaft that extends therefrom, an end effector disposed at a distal end of the shaft, at least one electrode operably coupled to the end effector and adapted to couple to a source of electrosurgical energy, a chromium nitride coating covering at least a portion of the electrode, and a hexamethyldisiloxane plasma coating covering at least a portion of the chromium nitride coating.

A forceps-type electrosurgical device is disclosed comprising, a fixed elongate body and a pair of moveable tips, arranged for engaging tissue in use, and extending from a forward end of the body. The tips are relatively moveable between a first position in which the tips are spaced apart and a second position in which the tips are brought together. The body further comprising an actuation member moveable relative to the body and connected to the tips such that a user may move the actuation member to result in movement of the tips between the first and second positions. The device may further comprise a suction port proximal to the tips.

An electrosurgical device can be delivered to a tissue site to provide supplemental sealing of vessels and/or vascular tissue that include suturing, stapling, or the like. The electrosurgical device is generally in the form of forceps, and includes an end effector assembly including opposing movable jaws. Each jaw includes a deformable pad or cushion including an electrode array positioned thereon. Each deformable cushion is configured to deliver a fluid, such as saline, during activation of the electrode array, thereby creating a virtual electrode which couples radiofrequency (RF) energy emitted from the electrode array into tissue in which the RF energy is converted into thermal energy. The deformable cushion and electrode array provide a controlled degree of compression upon the target tissue or vessel to maintain integrity of a suture, staple, or clip, as well as controlled energy emission for sealing, cauterizing, coagulating, and/or desiccating the target tissue or vessel.

A treatment instrument includes a treatment section treating a target of treatment such as a living tissue. The treatment section has an outer surface. A first resin film (first resin coating) covers part of the outer surface of the treatment section. A second resin film (second resin coating) covers at least a boundary between a region covered by the first resin film and a region not covered by the first resin film on the outer surface of the treatment section.

In one embodiment, the disclosure is directed to an integrated apparatus for delivering energy to a tissue. The integrated apparatus included a housing having a distal end and a tubular structure located within the housing forming a first annulus between the tubular structure and the housing. The tubular structure is configured to accept an energy delivery component and is configured to form a second annulus between the tubular structure and the energy delivery component. The first annulus and the second annulus are configured to communicate with each other proximate to the distal end of the housing.

The present disclosure relates to a surgical electrode assembly comprising: an electrode device comprising electrodes; a manipulating device; an electrode driving device configured to drive the electrodes, the manipulating device comprising an actuation mechanism; an inner tube having an inner tube proximal portion at a proximal end thereof, an inner tube distal portion at a distal end thereof, and an inner tube bending portion therebetween, the inner tube bending portion having a curvature, such that the inner tube distal portion and the inner tube proximal portion are disposed at an angle to each other; an outer tube having an outer tube proximal portion at a proximal end thereof and an outer tube distal portion at a distal end thereof, and an outer tube connecting portion therebetween, wherein the outer tube connecting portion is adapted to the inner tube bending portion, such that when manipulating the manipulating device to cause the inner tube and the outer tube to move relative to each other, the outer tube connecting portion allows the inner tube bending portion of the inner tube and the outer tube to move relative to each other in the longitudinal direction without interfering of the inner tube bending portion of the inner tube with the outer tube proximal portion and the outer tube distal portion of the outer tube. The technical effect lies in that bending tubes are provided which can greatly improve the convenience of the surgical electrode assembly entering a human body channel, and the electrode assembly may not interfere with the instrument used in conjunction therewith.
