    摘要： An electrode for an electrosurgical pencil, the electrode comprising an elongated body made of a conductive material and extending in an axial direction from a proximal end to a distal end, the proximal end configured for engaging the electrosurgical pencil and the distal end forming a blade configured for cutting or coagulation of tissue by electrosurgical energy received from the pencil, the blade being defined by two main surface portions on opposite sides of an axially extending intermediate plane and joined by an edge extending through the intermediate plane. To concentrate electrical energy at the edge and thereby facilitate a more precise cutting and less burnt tissue sticking to the electrode, the main surface portions has a first surface roughness, the edge has a second surface roughness being lower than the first surface roughness, and at least the main surface portions are covered by a surface coating comprising silicone.

    摘要： A surgical device and procedure are provided for smoothly and easily accessing tissue to perform microsurgery, including a capsulotomy of a lens capsule of an eye. The device includes a handpiece with a tip for insertion into an incision in the cornea of the eye. A sliding element is disposed within the handpiece and a suction cup is mounted to the sliding element. The sliding element can be translated to move the suction cup into and out of the handpiece. A compression mechanism associated with the suction cup and the handpiece compresses the suction cup for deployment through the tip of the handpiece. The suction cup can expand inside the anterior chamber into a cutting position on the lens capsule. A cutting element mounted to the suction cup is used to cut a portion of the lens capsule and to remove the portion from the eye. The cutting element may be mounted to a cutting element support structure in a way that prevents heating of the device.

    摘要： Electrosurgery blades for use in electrosurgical pencils used for electrosurgery. One exemplary embodiment of the electrosurgery blade includes a thin conductive member having opposing planar sides, a top, a bottom, a lead sharp cutting edge, an opposite non-cutting end and a planar horizontal opening therethrough located between the lead sharp cutting edge and the opposite non-cutting end, and a non-conductive coating covering both opposing planar sides of the thin conductive member and its planar horizontal opening such that at least a portion of the opposing planar sides adjacent to the lead sharp cutting edge remain exposed.

    摘要： This patent relates to a smoke evacuation tube and a telescopic smoke evacuation scalpel comprising the smoke evacuation tube. The smoke evacuation tube, comprises a first sleeve (6) and a second sleeve (26). An electrode (8) is mounted inside the first sleeve front section (61), and one end of the electrode (8) protrudes from one end of the first sleeve front section (61); the diameter of the first sleeve (6) is greater than the diameter of the second sleeve (26); a engaging structure used for assembling a lower conductive piece (7) is provided on or outside the second sleeve (26) and inside the first sleeve (6). The telescopic smoke evacuation scalpel comprises an upper conductive piece (10), which is embedded on the pencil body (4); the end of the first sleeve rear section (62) distant from the first sleeve front section (61) is provided with a connection hole.
