PIVOTING THREE-DIMENSIONAL VIDEO ENDOSCOPE A surgical camera assembly (10) includes a proximal member (110) defining a longitudinal axis ("X-X") and a distal member (120) defining a pointed tip (122) configured to puncture tissue ("T") to permit insertion of the surgical camera assembly (10) therethrough. The distal member (120) is pivotably coupled to the proximal member (110) and is movable relative thereto between a first position and a second position. First and second surgical cameras (300, 400) are disposed within the distal member (120) in fixed position and longitudinally-spaced relative to one another. Each of the cameras (300, 400) is oriented to define a viewing area ("Al", "A2") in a direction extending from an outer lateral periphery of the distal member (120). The cameras (300, 400) are configured to produce video images that are used in conjunction with one another to provide a three-dimensional video image of the internal surgical site "IX" _ -112 "A1" "A21 'X" t T A---10 126 120 -132 )4 (300 /T 130 |
