A surgical scalpel for cutting the tissue of a patient and for selectively applying an electrosurgical cutting current or an electrosurgical coagulation current from an electrosurgical generator to the patient, includes a scalpel body defining a contoured external surface configured to be held comfortably in the hand of a surgeon, and an electrically conductive blade, mounted on and extending from the scalpel body, for cutting the tissue of a patient and for selectively applying electrosurgical cutting current or electrosurgical coagulation current to the tissue of a patient. The scalpel further includes a cable having an electrical connector for electrical connection to the electrosurgical generator, and manual switch means, mounted on the scalpel body, for controlling the application of electrosurgical cutting current and electrosurgical coagulation current to the tissue of a patient.

Electrosurgical scalpel

Mechanism for attaching a high pressure tube to an opening in a housing using a tapered opening into which a high pressure tube is inserted. A fitting has one end positioned about the tube end and is then press fitted not only to the housing on an outer diameter fitting section but also inwardly against the tube end as well as the other fitting end being press fitted to the housing to further secure the fitting to the housing, all of the press fits providing high pressure seals. The fitting other end also provides for prealignment of a fitting cross passage with a housing side passage so that high pressure fluid flowing between the tube and the side passage has minimal directional change in passing from the cross passage to the side passage. The fitting other end is adapted to receive press fitting force in axial alignment with the fitting.

High pressure tube attachment mechanism

Various embodiments of mechanism for attaching a high pressure tube to an opening in a housing using a tapered opening into which a high pressure tube end is inserted. A securing device is positioned about the tube end and the securing device is press fitted into place in the opening so that it is press fitted not only to the housing on an outer diameter portion but also inwardly against the tube end, sealing the opening and the tube so as to hold about 5,000 p.s.i. pressure and also securing the tube against forces tending to move the tube axially or rotationally so as to loosen the tube.
