Abstract: A double cutting blade with a center vertical blade, which slices a margin of tissue around the surgical site. This blade permits thereby the positive establishment of tumor or diseased tissue limits by delineating the margin of normal tissue that is free of tumor or diseased tissue.The vertical blade of the margin blade cuts a strip of skin or tissue out to form a trench of a width the same as the width between the knives wherever the margin blade, sometimes called a trenching blade, travels so that the resultant trench conforms exactly to the normal tissue surrounding the diseased tissue or tumor, thereby saving as much normal tissue as possible.

Abstract: A method is disclosed for implanting hair into human skin comprising the steps of inserting an end of a hollow outer needle into skin to form a pit in the surface thereof, sliding an inner needle within the outer needle to position an end of the inner needle supporting a bulbous end of a hair within the skin pit adjacent the end of the outer needle, and extracting the outer and inner needles from the skin pit.Apparatus is also disclosed for implanting hair into human skin which apparatus comprises a hollow outer needle having a relatively sharp end for piercing skin, a hollow inner needle slidably disposed within the hollow outer needle and having a centrally apertured relatively blunt end for receiving a hair therethrough and for supporting a bulbous hair end on the surface thereof, and means for moving the inner needle blunt end between positions remote and positions closely adjacent the outer needle sharp end.

An outside cutting sleeve receives the hollow tube therein and is provided with a rotary cutting edge which is adapted to angularly turn about the axis of the hollow tube to sweep at least a portion of the hook face to thereby cut an object clamped at the hook by the rod.

Abstract: A device for intubation of the tracheal passage comprising a tube through which gas can be administered and an occlusion means to seal the annular space around the tube when it is positioned in a tracheal passage. The occlusion means is formed as a canopy of flexible material having a top part traversed by said tube in an air-tight junction with an inflatable annular chamber extending around the wall of the canopy. Inflation of this chamber distends the canopy against the tracheal wall and simultaneously creates a second annular chamber between the inner surface of the canopy and the outer surface of the tube. The bottom of the canopy is open during positive pressure ventilation, for allowing an upward flow of gas via the annular space into said second chamber to inflate and distend the canopy against the tracheal wall independently of inflation of said first annular chamber.
