ABSTRACT:
An improved surgical snare apparatus includes an elongated tubular tip extending from a control handle. The ends of a single U-formed snare wire extend through the tip and out of its proximal end where they are secured to a control element in the handle that enables moving of the wire. The distal end is modified from conventional snares to allow the contracted snare loop to be substantially nested within the tip. In the fully contracted nested position, the wire substantially closes the modified distal end so that the sharp cutting edges of the distal end are not exposed to contact with body tissue during insertion into an incision or opening. Thus, the combination of the modified distal end and the single wire nested within presented a tip the minimizes trauma during insertion.
The configuration of the expanded single wire loop is modified from conventional dual wire snare loops into a more rounded form which is easier to manipulate around tissue to be severed, a polyp for example.
