Surgical Instrument with Flexible Shaft
First Claim
1. A surgical instrument comprising:
- an elongate body defining a longitudinal axis and a lumen therethrough, the elongate body defining an aperture in communication with the lumen;
an elongate shaft disposed at least partially within the lumen of the elongate body;
a collar mounted at least partially on the elongate shaft; and
an end effector coupled with the elongate shaft, wherein the elongate shaft is transitionable between a first position in which the elongate shaft is aligned with the longitudinal axis and a second position in which a portion of the elongate shaft having the collar mounted thereon transversely bends and protrudes through the aperture, thereby causing the end effector to move along the longitudinal axis with respect to the elongate body.

Abstract
A surgical instrument includes an elongate body, an elongate shaft, a collar, and an end effector. In particular, the elongate body defines a longitudinal axis, a lumen therethrough and an aperture in communication with the lumen. The elongate shaft is disposed at least partially within the lumen of the elongate body. The collar is mounted at least partially on the elongate shaft. The effector is detachably coupled with the elongate shaft. The elongate shaft is transitionable between a first position in which the elongate shaft is aligned with the longitudinal axis and a second position in which a portion of the elongate shaft having the collar mounted thereon transversely bends and protrudes through an aperture, thereby causing the end effector to move along the longitudinal axis with respect to the elongate body.
