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.

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. - View Dependent Claims (20)

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. - View Dependent Claims (22)

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. - View Dependent Claims (24, 25, 26)

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.
