Abstract

The present disclosure relates to a retraction system for retracting body organs and/or body tissue in a body cavity. The retraction system includes an elongate shaft configured and dimensioned to be inserted into the body cavity, a retractor device operatively associated with the elongate shaft, the retractor device having a first configuration for insertion into the body cavity and at least a second configuration for retraction of the body organ, and at least one anchor member operatively coupled to the retractor device for anchoring the retractor device to a wall of the body cavity.

Claims

1. A retraction system, comprising:

a shaft configured and dimensioned to be inserted into a body cavity;

a retractor device operatively associated with the shaft, the retractor device having a first configuration for insertion into the body cavity and at least a second configuration for retraction of the body organ; and

at least one securement member operatively coupled to the retractor device for securing the retractor device to a wall of the body cavity.

2. The retraction system of claim 1, wherein the at least one securement member includes at least one suture operatively coupled to the retractor device.

3. The retraction system of claim 2, further comprising:

a plurality of anchors operatively couplable to the at least one suture, wherein each anchor is configured and adapted to anchor the sutures with respect to the wall of the body cavity.

4. The retraction system of claim 1, wherein the retractor device includes a pair of resilient bands having distal ends operatively connected to one another, the bands being movable between an open position forming a retracting surface and a closed position.

5. The retraction system of claim 4, wherein the shaft defines a lumen and wherein the retractor device is positionable within the lumen when in the closed position.

6. The retraction system of claim 1, wherein the retractor device is a sling having a pair of opposed ends.

7. The retraction system of claim 1, wherein the retractor device is operatively connected to the shaft at a location along a length of the shaft.

8. The retraction system of claim 7, wherein the at least one securement member is a suction device operatively connected to a distal end of the shaft, the suction device being configured and adapted to transmit a vacuum effect to the wall of the body cavity.

9. The retraction system of claim 1, wherein the retractor device comprises a plurality of blade members movable to a fanned-out position.

10. A method of retracting, the method comprising the steps of:

inserting a retraction system having a retraction device and a securement member into the body cavity through an insertion point on a first side of the body cavity, the insertion point being located at a position which is spaced a longitudinal distance from a transverse plane defmed by a body organ and/or tissue to be retracted;

securing the at least one securement member to a wall of the body cavity opposite the first side, the at least one securement member being secured to the wall at a position spaced a longitudinal distance from the transverse plane; and

urging the retractor device against the body organ and/or tissue so as to displace the body organ and/or tissue in the longitudinal direction.
