Abstract
A laparoscopic tissue removal device for use by fingers of a hand comprising an elongate tubular member with proximal and distal extremities and having a bore extending therethrough. An elongate tubular member has an outer diameter and an elongate tubular sheath is formed of a tubular woven braid material having proximal and distal extremities. A length extends between the proximal distal extremities. The elongate tubular sheath has a passage extending from the proximal extremity to the distal extremity. The tubular woven braid material of the elongate tubular sheath has an initial configuration and an open weave construction permitting the elongate tubular sheath to enlarge beyond its initial diameter to a diameter substantially greater than the initial diameter. The proximal extremity of the elongate tubular sheath is secured to the elongate tubular member. The distal extremity of the elongate tubular sheath has a distal portion capable of assuming an outwardly flared configuration which when free has an open end that has a diameter substantially greater than the initial diameter of the passage extending through the elongate sheath. An outer sleeve is slidably mounted on the elon…
