Abstract
645,492. Surgical optical instruments. FOSSATI, R. Sept. 10, 1947, Nos. 24845 and 24846. Convention dates, May 4, 1946 and Sept. 27, 1946. [Class 81(ii)] A surgical appliance comprising a cannula which is introduced into the body by means of a trocar or perforator is characterized by a longitudinal slot in its wall so that an endoscope or similar optical device together with a surgical instrument can be simultaneously passed through the hole in the anatomical wall. In one form of the device a trocar 2, of substantially the same diameter as the cannula 1 is placed in the cannula as shown and then inserted through the anatomical wall. The trocar is then withdrawn, leaving the cannula in position, into which a telescope may be inserted. A slot extending along one side of the cannula, at its outer end, is opened by means of a hinged flap 7 operated by a knob 8, thereby slightly stretching the hole in the wall, and any desired surgical instrument is introduced through a corresponding keyhole slot in the end plate 6. In modified forms the flap is not used but the instrument is introduced first and pressed into the narrow part of the keyhole slot, after which the telescope is inserted. More convenient separation of the instrument from the endoscope may be provided by having a pivoted lever between the two, Fig. 8, (not shown), or by having two concentric tubes, both slotted, which may be rotated relatively to each other after the instrument has been inserted; Figs. 6 and 7, (not shown).
