As representative of the present invention, the Figures illustrate an apparatus 100 (FIG. 1) for use in percutaneous surgery in association with a cannula 10 (FIG. 20). The apparatus 100 includes a base 110, a structure comprising a first part 200 and a second part 300, a screw mechanism 400 connected between the base and the second part, and a cannula clamp 500 connected with the base. The first part 200 is adapted to be fixed to a camera head 99. The second part 300 is adapted to be secured to the first part. The cannula clamp 500 is adapted to be clamped to the cannula 10. The base 110, first part 200, second part 300, and camera head 99 are rotatable relative to the cannula clamp 500.
[0053]FIG. 19 shows an actuatable device 35 for expanding the second tubular portion 40 from the contracted condition to the expanded condition. The actuatable device 35 comprises a manually operated expansion tool 37. The expansion tool 37 resembles a common pair of scissors and has a pair of legs 33 pivotally connected to one another. The expansion tool 37 includes a frustoconical end section 38 formed by a pair of frustoconical halves 39. Each of the frustoconical halves 39 extends from a respective one of the legs 33 of the expansion tool 37. It is contemplated that other suitable means for expanding the second tubular portion 40 toward the expanded condition could be employed, such as an inflatable balloon (not shown).
However, if rotation of the base 110 more than 10° is desired, the manual force applied to the base can continue to rotate the base relative to the cannula clamp 500 and the cannula 10. As should be apparent, the base 110 and the camera head 99 (and the attached endoscope) may rotate at least 300° about the central axis 14 of the cannula 10 and be adjustably fixed at 10° increments. This enables the surgeon to view different parts of the surgical site, as desired. The sleeve part 600 of the cannula clamp 500 can be easily removed from the central aperture 125 for cleaning, maintenance, etc. of the parts by disengaging the set screws 357 from the groove 620 and the recesses 630, or by overcoming the biasing force applied by the ball plungers 700 to the sleeve part.
