摘要： An apparatus and method for minimally invasive surgery using a cutting tool with rotational cutting edges. The surgical instrument includes a tube having a distal end and a cutting edge at the distal end. A handle is attached to the proximal end of the tube. Within the tube is a shaft having a longitudinally extending blade at its distal end that is adjacent to the distal end of the tube. The blade is revolvable about the longitudinal axis of the instrument to provide rotational cutting action. One or both of the blade and the cutting edge on the tube can be electrically energized to provide for electrocauterization of the body tissue being cut.

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 skewed relative 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 axes of the legs, and with the loop directed away from the surgical tool. Thus, in operation, when the surgeon locates a vessel and side branch of interest, the surgeon extends the retractor to cradle the vessel in the dissection cradle. Once cradled, the retractor may be fully extended to urge the vessel away from the axis of the cannula to isolate the side branch for exposure to the surgical tool. The dissection cradle may include a forward shoulder for positioning a suture loop. A forwardly-projecting tensioner supports a length of suture from the loop to maintain the loop in tension for transport along the vein. During advancement, the suture loop is safely maintained in place due to the tension provided by the tension mount and the support provided by the shoulder. Upon reaching the surgical site of interest, the retractor is retracted, causing the suture loop to be displaced onto the vein at the desired position. In one embodiment, the loop is tightened by pulling on the length of suture near the proximal end of the cannula to constrict the suture loop about the vein near the distal end of the cannula.

摘要： A system prevents oxidation of a laser cut workpiece by utilizing a laser source that utilizes laser source with an inert gas, such as argon or helium, rather than air or oxygen, to create the slots or kerfs which form the pattern cut into the workpiece. The system introduces oxygen gas through the workpiece as it is being laser cut to oxidize any slag or dross created during the laser cutting process. Oxygen or a mixture of oxygen with other gases cools the slag and the workpiece while at the same time oxidizing the slag to either completely burn or partial burn the slag before it strikes an exposed surface of the tubular member.

摘要： A retractor and a surgical tool are positioned at the distal end of the cannula. A dissection cradle is located at the distal end of a distal portion of the retractor that is resiliently skewed relative to the cannula axis, and includes two substantially parallel, spaced legs with the retractor shaped in a loop therebetween. The procedure includes locating a vessel and side branch of interest and extending the retractor to retain the vessel in the dissection cradle to urge the vessel away from the axis of the cannula in order to isolate a side branch for exposure to the surgical tool.

Once cradled, the retractor may be fully extended to urge the vessel away from the axis of the cannula to isolate the side branch for exposure to a surgical tool. One of the legs supporting the retractor is hollow and includes a spray nozzle disposed in the distal end of the retractor to form an irrigation system. The proximal end of the hollow leg communicates with a fluid inlet which receives irrigation fluid under pressure for washing the endoscope lens. The spray nozzle on the retractor may be positioned to wash the endoscope lens, or upon selective extension of the retractor out of the cannula, the spray nozzle may be positioned to direct the spray of irrigation fluid at a remote surgical site.

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.
