<p>The invention includes a multiple action surgical endoscopic instrument comprising first (7) and second (8) blades. A support carries first (15) and second (16) adjusting mechanisms which provide independent angular adjustment of the first (7) and second (8) blades, respectively. The support also carries a third adjusting mechanism (4) which provides adjustment of the separation between the first (7) and second (8) blades. The invention also includes a diagnostic surgical endoscopic instrument comprising a tapered tube (31) and a handle (35) which is detachably secured at the proximal end of the tube (31) to a selected one of diametrically opposed positions relative to the axis of the tube (31). A process according to the invention includes inserting the distal ends of the first (7) and second (8) blades through an incision in a patient; adjusting the first (15), second (16), and third (4) adjusting mechanisms; and inserting instruments through the first (7) and second (8) blades and the incision into the patient.</p> |
