Abstract
An optical obturator apparatus includes an obturator sleeve defining a longitudinal axis and having a longitudinal bore for receiving surgical instrumentation and a transparent window mounted to the obturator sleeve and being dimensioned and configured to pass through tissue. The transparent window is mounted for movement between a first position in general alignment with the longitudinal axis of the obturator sleeve and a second position radially displaced from the longitudinal axis to thereby expose the longitudinal bore of the obturator sleeve to permit passage of the surgical instrumentation. The transparent window may include a cutting blade, or alternatively two cutting blades, adapted to penetrate tissue
Claims25
An optical access apparatus, which comprises:
- a sleeve having open proximal and distal ends for receipt of surgical instrumentation and defining a longitudinal axis;
- and
- a translucent window mounted to the sleeve and being dimensioned and configured to separate tissue, the translucent window being mounted for movement between a first position in general alignment with the longitudinal axis of the sleeve and a second position radially displaced from the longitudinal axis to thereby expose the distal end of the sleeve to permit passage of the surgical instrumentation.
A surgical optical access system, which comprises:
- a cannula assembly having a cannula with open proximal and distal ends and a seal housing having a seal and being mounted on the proximal end of the cannula, the cannula defining a longitudinal bore for reception of surgical instrumentation;
- a window for permitting passage of light into the cannula and being mounted on the distal end of the cannula;
- and
- locking structure for securing an endoscope within the cannula assembly, the window permitting the passage of light to the endoscope when the endoscope is disposed within the cannula.
