Abstract
A surgical instrument having an elongated shaft to which is attached an inflatable balloon, commonly referred to a "balloon dissector", for dissecting a desired layer of internal bodily tissue from remaining tissue layers to create an operative space is disclosed. Alternatively, an instrument without a balloon can be used to perform a manual dissection. In one embodiment, the instrument has a tissue-contacting element in communication with the shaft distal end, and at least a portion of the tissue-contacting element is transparent. The instrument is adapted to receive an endoscope through its shaft and extend to adjacent the tissue-contacting element. The endoscope is supported and positioned in an extension assembly. The instrument provides for visualization using the endoscope as the instrument is advanced through tissue, but prevents direct contact between the tip of the endoscope containing the lens and the tissue. The extension assembly also enables the endoscope to be adequately positioned and supported beyond the shaft distal end. When the instrument incorporates the balloon, the endoscope can extend into the lumen of the inflated balloon. In this way, improved visualization during use can be obtained.
