Abstract
A surgical apparatus is provided having a first instrument and a second instrument which are independently operable, but may be used in tandem. The first instrument may comprise a needle and the second instrument may comprise a snare for cutting, excising, or trapping tissue. An actuator extends the needle a fixed first length relative to a distal end of the catheter for independently extending or retracting the second instrument a variable second length relative to the catheter distal end. The needle may be biased to retract relative to the distal end of the catheter. The actuator has a support and a slider. The slider is connected to the support for movement in opposite directions relative the support to allow freedom of action. The first instrument is secured to the support and rail, and the second instrument is secured to the slider. A rail enables independent but non-simultaneous sliding movement of the first instrument, or needle, while the slider facilitates independent operation of the second instrument, or snare.
