Abstract

A retractor member is configured for insertion through a channel of an access member and for moving soft tissue at a treatment site that is accessible through the channel. The retractor includes a body having a proximal end and a distal end and spaced from each other along a longitudinal direction. The distal end defines a retractor blade and the body defines a first surface and a second surface opposite each other along a transverse direction substantially perpendicular to the longitudinal direction. The retractor includes an attachment device configured to selectively attach the body to a portion of the access member such that the body is extendable through the working channel while the body is attached to the portion of the access member.

First claim

What is claimed:

1 . A retractor member configured for insertion through a channel of an access member and for moving soft tissue at a treatment site accessible through the channel, comprising:
a body having a proximal end and a distal end and spaced from each other along a longitudinal direction, the distal end defining a retractor blade, the body defining a first surface and a second surface opposite each other along a transverse direction substantially perpendicular to the longitudinal direction; and an attachment device configured to selectively attach the body to a portion of the access member such that the body is extendable through the working channel and is translatable relative to the access member along the longitudinal direction while the body is attached to the portion of the access member.
