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.
Claims6
A retraction system, comprising:
- a shaft configured and dimensioned to be inserted into a body cavity;
- a retractor device selectively positionable within a lumen of the shaft, the retractor device includes a pair of resilient bands secured to one another at a first end and a second end, and a sheath encasing the pair of resilient bands, the retractor device includes a biased first configuration, wherein the pair of resilient bands each have a substantially linear configuration and wherein the retractor device is positionable within the lumen of the shaft, and at least a second configuration, wherein the pair of resilient bands each have an arcuate profile, for retraction of the body organ, wherein the retractor device automatically assumes a second configuration when withdrawn from the shaft;
- and
- at least one securement member operatively coupled to the retractor device for securing the retractor device to a wall of the body cavity, wherein the at least one securement member includes a plurality of sutures operatively coupled to each end of opposite ends of the retractor device.
1 more element
A retraction system, comprising:
- a shaft configured and dimensioned to be inserted into a body cavity;
- a retractor device selectively positionable within the shaft, wherein the retractor device is operatively connected to the shaft at a location along a length of the shaft and spaced a distance from a distal end of the shaft, wherein the retractor device has a first configuration in which the retractor device is housed within the shaft and a second configuration in which the retractor device projects outwardly from the shaft;
- and
- at least one securement member operatively coupled to the retractor device for securing the retractor device to a wall of the body cavity, 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.
1 more element
A method of retracting, the method comprising the steps of:
- inserting a retraction system 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 defined by a body organ and/or tissue to be retracted, the retraction system including:
- a shaft configured and dimensioned to be inserted into a body cavity;
- a retractor device selectively positionable within a lumen of the shaft, the retractor device includes a pair of resilient bands secured to one another at a first end and a second end, and a sheath encasing the pair of resilient bands, the retractor device includes a biased first configuration, wherein the pair of resilient bands each have a substantially linear configuration and wherein the retractor device is positionable within the lumen of the shaft, and at least a second configuration, wherein the pair of resilient bands each have an arcuate profile, for retraction of the body organ, wherein the retractor device automatically assumes a second configuration when withdrawn from the shaft;
- and
- at least one securement member operatively coupled to the retractor device for securing the retractor device to a wall of the body cavity;
- 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.
