Surgical access device comprising internal retractor
View Patent ↗Devices, methods, and systems provide a surgical access device comprising an internal retractor device integrated with or coupled to a body wall or wound retractor. The wound retractor retracts an opening in a body wall into a body cavity, while the internal retractor permits a user to control the positions of internal structures within the body cavity, thereby permitting a user to define a surgical field. Embodiments of the internal retractor are adjustable.
1. A surgical access device adapted to allow a user to control the position of internal structures within a body cavity, comprising:
a wound retractor comprising an outer ring having a diameter greater than an opening into the body cavity and being adapted for disposition exteriorly of the opening, an inner ring having a diameter greater than the opening into the body cavity and being adapted for disposition interiorly of the opening, and a tubular sheath extending between the outer ring and the inner ring; and
an internal retractor coupled to the inner ring in an operative state of the surgical access device, the internal retractor comprising a deformable planar frame, wherein in the operative state, at least a portion of the internal retractor extends distally of the inner ring into the body cavity.
2. The surgical access device of claim 1 , wherein the outer ring of the wound retractor is rotatable around an annular axis thereof, thereby permitting adjustment of an effective length of the tubular sheath between the inner ring and the outer ring.
3. The surgical access device of claim 1 , wherein the internal retractor and the wound retractor are integrated.
4. The surgical access device of claim 1 , wherein the internal retractor is user coupled to the wound retractor in the operative state.
5. The surgical access device of claim 1 , wherein the internal retractor further comprises a connection member, wherein the connection member couples the internal retractor to the wound retractor.
6. The surgical access device of claim 1 , wherein the internal retractor comprises at least one window therethrough.
7. The surgical access device of claim 1 , wherein the frame defines a generally rectangular shape.
8. The surgical access device of claim 1 , wherein the frame defines a generally nonrectangular shape.
9. The surgical access device of claim 1 , wherein the frame defines a generally serpentine shape.
10. The surgical access device of claim 1 , wherein the frame comprises at least one of a lattice, a mesh, a solid sheet, and a perforated sheet.
11. The surgical access device of claim 1 , further comprising a cover disposed over the frame.
12. The surgical access device of claim 1 , wherein the frame comprises a plastically deformable material.
13. The surgical access device of claim 1 , wherein the frame comprises an elastically deformable material.
