Device and method for extraction of tissue from a subject

1 . A surgical device for extraction of a resected tissue or the like from a body comprising an elongate portion having a substantially rounded end; a sleeve assembly comprising an anchor portion for contacting a region around the resected tissue when inflated or extended to a sufficiently rigid state, and a body portion shaped and dimensioned to receive the resected tissue; the body portion comprises a first end, a second end and a pliable sleeve; the first end and the second end each having a respective diameter greater than a desired diameter of the natural orifice or tissue opening; wherein the pliable sleeve is disposed between the first end and the second end in a manner which a distance between the first end and the second end is adjustable; and a crimping mechanism disposed between the first end and the second end of the pliable sleeve, wherein the crimping mechanism is configured to slide in a longitudinal direction of the pliable sleeve, the crimping mechanism comprising a crimping ring disposed circumferentially around the pliable sleeve, and a support ring disposed along an inner wall of the pliable sleeve, such that the sleeve is sandwiched between the crimping ring and the support ring.

2 . The surgical device of claim 1 , wherein the elongate portion of the device comprises a cavity adapted to receive the sleeve assembly or part thereof.

3 . The surgical device of claim 1 , wherein the elongate portion may comprise a first elongate part and a second elongate part, the first elongate part and the second elongate part joined at an angle.

4 . The surgical device of claim 1 , wherein the elongate portion is formed of or from biocompatible materials.

5 . The surgical device of claim 1 , wherein the anchor portion is configured to inflate or extended to a sufficiently rigid ring in a body cavity and at a pre-determined temperature.

6 . The surgical device of claim 1 , wherein the resected tissue is a resected human or animal colon tissue.

7 . The surgical device of claim 1 , further comprising a spine portion connecting the first end and the second end or positioned between the first end and the second end, the spine portion comprises at least one releasable lever mechanism to move at least one of the first end and the second end between a collapsed state and a non-collapsed state.

8 . The surgical device of claim 1 , wherein the crimping ring comprises a lever operable to compress the crimping ring, such that longitudinal movement of the locking means, with respect to the first and second ends, is prevented.

9 . The surgical device of claim 1 , wherein the support ring has a plurality of bumps or other textures disposed along a circumference of the support ring.

10 . A method of using the device of claim 1 to extract a resected specimen, comprising the steps of:

a. collapsing and packing the sleeve assembly into a cavity formed on the elongate device;

b. inserting, via the substantially rounded end, the elongate device into a natural canal of a mammalian subject;

c. moving the elongate device towards a body cavity where the resected specimen is located;

d. inflating or extending the anchor portion for attachment to a surface of an inner wall of the body cavity of the mammalian subject, extending the pliable sleeve in a manner to define a channel between the first end and second end;

e. sliding the crimping mechanism along the longitudinal direction of the pliable sleeve prior and clamping the pliable sleeve between the support ring and the crimping ring; and

f. removing the resected specimen through the channel.

11 . The method of claim 10 , wherein the step of removing the resected specimen includes a step of inserting a grasping or crimping device and pulling the resected specimen through the channel.
