Abstract

A universal retractor and sealing system used in conjunction with surgical instruments such as cannulas, endoscopes surgical or non-surgical instruments or other tools. The user manipulates the instrument so as to create a projecting surface located inside the cavity. An outward force applied to the instrument body seats the projecting surface against the inner wall of the cavity, which can be used to form at least a partial seal against fluid. With the projecting surface positioned against the cavity wall, the instrument can be manipulated so as to act as a retractor, expanding the workable area and/or the field of view as required.

Claims

1. A system for sealing and affixing an instrument body within an opening comprising:

a body having proximal and distal ends;

an expandable portion that increases in effective size to form a projecting surface in proximity to a distal end of the body.

2. The system of claim 1, further comprising an outer sleeve located on the body that is moveable between an installation state and a deployed state, in the installation state the projecting surface is in a retracted position against the body and in the deployed state the projecting surface extends away form the body.

3. The system of claim 2, wherein the projecting surface is annular.

4. The system of claim 2, wherein the projecting surface comprises a plurality of fingers.

5. The system of claim 2, wherein a distal end of the sleeve is fixed proximate to the distal end of the body.

6. The system of claim 2, wherein the body has a stop attached in proximity to the distal end.

7. The system of claim 2, wherein the sleeve has at least one folding line formed therein.

8. The system of claim 2, wherein the sleeve is lockable in at least one position relative to the body.

9. The system of claim 2, wherein the sleeve further comprises a handle.

10. The system of claim 9, wherein the handle is annular.

11. The system of claim 2, wherein the body is connected to a cannula.

12. The system of claim 2, wherein the body is connected to an endoscope.

13. The system of claim 2, wherein the body is connected to a surgical or non-surgical instrument or tool.

14. The system of claim 1, further comprising a seal located in the body.

15. The system of claim 1, further comprising a pierceable sealing cap attached to a proximal end of the body.

16. The system of claim 1, further comprising an outer clamp that is connected to the body.

17. The system of claim 1, further comprising a seal located at a proximal end of the body, and openings through a sidewall of the body located distal to the seal.

18. The system of claim 1, further comprising a baffle located at or above a proximal opening of the body.

19. A method of using an instrument inserted into a surgical site comprising the steps of:

providing an instrument to be inserted into a surgical opening having a stop attached thereto with a sleeve, the sleeve having an installation and deployed state, in the installation state the projecting surface is in a retracted position against the body and in the deployed state the projecting surface extends away form the body;

inserting the instrument and sleeve through tissue into a surgical site;

sliding the sleeve against the stop thereby altering the sleeve profile to the deployed state.

20. The method according to claim 19, further comprising:

pulling on the instrument as a retractor to provide additional space for surgical operations.

21. A method of using an instrument inserted into a surgical site comprising the steps of:

providing an instrument with first and second end to be inserted into a surgical site;

providing a sleeve, the sleeve having an alterable profile with a projecting surface pre-formed therein,

placing the sleeve over the instrument;

attaching the sleeve proximate to the first end to the instrument;

placing tension on the sleeve so as alter its profile to a generally cylindrical form;

inserting the instrument and sleeve into a surgical site;

releasing the sleeve thereby allowing the sealing surface to reform inside the bodily cavity.

22. The method according to claim 21, further comprising:

using the instrument as a retractor to provide additional space for further surgical operations.

23. A system for sealing and affixing a body within an opening comprising:

an elongated body having proximal and distal ends;

the body having at least one projecting surface attached thereto;

the projecting surface being movable between a stowed and a deployed state so as to form a projecting surface in proximity to a distal end of the body.

24. The system of claim 23, wherein the projecting surface is deployed by a handle.

25. The system of claim 23, wherein the projecting surface is deployed by a rotatable collar located near the proximal end of the body.

26. The system of claim 23, wherein the sealing surface is an inflatable bladder.

27. A method for sealing and affixing a body within an opening comprising:

providing an elongated body having proximal and distal ends;

the body having at least one projecting surface in contact therewith;

inserting the body into the opening and deploying the projecting surface in proximity to a distal end of the body.

28. A cap for sealing an end of a cannula, comprising:

an upper surface with a drip-proof opening for insertion of an instrument therethrough located in a top thereof;

a side wall with at least one channel having an undercut section; and

a sealing lip located along a bottom edge of the side wall.
