摘要： A retractor and a surgical tool are positioned within a cannula, and a dissection cradle of the retractor is positioned at the distal end of the cannula. The retractor includes a first portion with an axis approximately parallel to the axis of the cannula and a second portion with an axis at an angle to the axis of the cannula. The dissection cradle is located at the distal end of the second portion of the retractor, and may include two substantially parallel, spaced legs with the retractor shaped in a loop between and in a plane skewed relative to the axis of the legs, and with the loop directed away from the surgical tool. Thus, in operation, when the surgeon locates a vein and side branch of interest, the surgeon extends the retractor to cradle the vein in the dissection cradle. Once cradled, the retractor may be fully extended to urge the vein away from the axis of the cannula isolate the side branch for exposure to the surgical tool. In another embodiment, the cannula includes a sheath which encases the curved, resilient retractor at a first position to retain the retractor in substantially straight orientation, and which encases the retractor at a second position that allows the retractor to extend at an angle relative to the axis of the cannula.

The retractor includes a dissection cradle that is resiliently supported along an axis skewed relative to the axis of the cannula. The dissection cradle, in operation, is extended to cradle the target vessel, and the retractor may be fully extended to urge the vessel away from the axis of the cannula to isolate a side branch for exposure to a surgical tool. The retractor includes a hollow support and a spray nozzle disposed in the distal end of the retractor to form an irrigation system and lens washer that can be selectively positioned to direct the spray of irrigation fluid at a remote surgical site or at an endoscopic lens.

摘要： An assembly of cannula and endoscope and dissection tip facilitate surgical procedures at remote surgical site in tissue of a patient. Relative rotation of the cannula about the endoscope from clamped rotational fixation of the cannula and endoscope is made possible by flexing a resilient clamping segment, and such relative rotation promotes convenient positioning of an eccentric tissue-dissecting tip about a vessel being harvested from within tissue of a patient. Color tinting of the tip or color-tinted illumination of tissue at a remote surgical site enhances contrasting visualization through the tip via the endoscope among the tissue types encountered at the surgical site within a patient. A tool bridge or lateral support mounts to a more rigid component such as an endoscope that extends from the proximal end of a cannula to support a more flexible surgical instrument also extending from the proximal end of the cannula.
