Abstract

A surgical device comprising (a) a tubular housing having a longitudinal bore extending therethrough, (b) a first elongate member extending through the longitudinal bore of the housing, and having a proximal and a distal segment, where at least part of the distal segment comprises an elastic material, especially a super elastic material, and wherein the distal segment assumes a first shape when extended from the longitudinal bore, and a second shape when withdrawn into the bore, (c) a second elongate member also having a proximal and a distal segment, the second elongate member extending substantially parallel to the first elongate member so that it is moved by the first elongate member, when the first elongate member changes from its first to its second shape and vice versa, the second elongate member being rotatable relative to, and substantially about, the axis of the first elongate member, and (d) an operating head secured to the distal segment of the second elongate member so that it (i) is moved with the second elongate member when the first elongate member changes from its first to its second shape and (ii) can be rotated by the second elongate member substantially about the axis of the first elongate member.
