The electrosurgical device comprises at least one hollow body of elongated shape and having: a gripping portion, in turn, comprising a proximal ending part connectable to a current generator and to feeding means of an electro-conductive fluid; a contact portion comprising a distal ending part having one active electrode and one neutral electrode adapted to come into contact with the body of a patient; and at least one tubular duct passing through the hollow body and having one feeding hole of the fluid formed on the proximal ending part, and one delivery hole of the fluid formed on the distal ending part; the delivery hole is at least partially circular and extends around at least one of the electrodes.

Embodiments of the present disclosure provide a method and apparatus for filtering and surgical procedures. An exemplary apparatus includes an evacuation tube having a filter, a long axis and a hollow conduit extending through the long axis, the hollow conduit fluidly connecting a tube inlet and a tube outlet, the filter located within the hollow conduit operable to remove particles from a flow passing through the hollow conduit from the tube inlet to the tube outlet.

A knife limit for a surgical instrument includes a housing having a shaft extending therefrom configured to support an end effector at a distal end thereof, the end effector including first and second jaw members. One or both of the jaw members including a knife channel defined therein and extending therealong to a distal portion thereof. A knife assembly is disposed within the housing and cooperates with a trigger to translate a knife within the knife channel to the distal portion of the jaw member upon actuation thereof. A knife limit button is disposed within the housing and is configured to limit the distal translation of the knife within the knife channel upon selective actuation thereof. The knife limit button is movable between a first position allowing full translation of the knife within the knife channel and a second position limiting distal translation of the knife within the knife channel.

Surgical systems can include evacuation systems for evacuating smoke, fluid, and/or particulates from a surgical site. A surgical evacuation system can be intelligent and may include one or more sensors for detecting one or more properties of the surgical system, evacuation system, surgical procedure, surgical site, and/or patient tissue, for example.

An electrosurgical device having first and second poles; blade electrode with a metal shim having two opposing faces and one or more facets, a nonconductive coating which covers at least the faces and a portion of the facets of the metal shim, while a distal portion of the one or more facets remains uncovered by the nonconductive coating; a lateral electrode comprised of a broad shim having one or more conductive faces and is placed parallel to the blade electrode so that at least one of the one or more conductive faces is exposed and a distal end of the blade electrode protrudes from the lateral electrode; the lateral electrode is fixed stationary relative to the blade electrode; the nonconductive coating insulates the blade electrode from the lateral electrode; and the first pole is connected to the blade electrode and the second pole is connected to the lateral electrode.

A power supply unit for a direct-current galvanic electrolysis device has a housing configured to be held in a hand of a patient and having a conductive outer surface forming a first electrode that is adapted to make electrical contact with the hand of the patient while the housing is being held. In addition, the power supply unit has an electrical power source, an electrical connector supported for detachably coupling to a second electrode in the form of a needle handpiece, a regulating circuit coupled to the power source and having positive and negative output nodes. The regulating circuit positive output node is electrically coupled to the first electrode and the negative output node is electrically coupled to the connector and thereby, in use, to the second electrode of the needle handpiece.

This adhesion prevention film for medical devices is a single-layer or multilayer adhesion prevention film that is formed on the surface of a medical device. This adhesion prevention film for medical devices comprises an outermost layer that contains a plurality of conductive particles and a resin having a continuously usable temperature of 200° C. or higher. The surface of the outermost layer is provided with recesses and projections by having parts of the plurality of conductive particles exposed from the resin.

Lighting devices are disclosed for use with handheld surgical instruments, along with holsters for supporting surgical instruments with lighting devices thereon and kits containing surgical instruments and lighting devices.

An electrode assembly for an electrosurgical pencil includes an insulative housing. A locking plate is supported at a distal end of the insulative housing about a pivot, the locking plate including a series of locking holes defined therein. A tip assembly is coupled to a distal end of the locking plate and is configured to treat tissue. A connection is coupled to a proximal end of the insulative housing and is electrically coupled to the tip assembly. One or more locking fingers is operably disposed within the housing and is movable between a first position allowing rotation of the locking plate and the tip assembly about the pivot and a second position preventing rotation of the locking plate and the tip assembly. The finger(s) is configured to engage a corresponding one of the series of locking holes to prevent rotation of the locking plate and the tip assembly.

An electrosurgical apparatus is provided including a housing, a flexible shaft, and a distal tip. The housing may further be coupled to an electrosurgical generator and gas supply. The distal tip of the electrosurgical apparatus may be grasped by a grasping tool, such that the orientation and position of the distal tip relative to the housing may be manipulated to achieve a plurality of positions. The electrosurgical apparatus provides electrosurgical energy and inert gas to an electrode within the distal tip of the electrosurgical apparatus to generate a plasma beam. In one aspect, the electrode is a retractable blade such that the electrosurgical apparatus can be used for mechanical and electrosurgical cutting during surgery when the electrode is in an extended position and for cold plasma applications during surgery when the electrode is in a retracted position.
