Surgical access assembly and method of use therefor

Abstract

A surgical access assembly includes a sleeve assembly, a base member, and a sealing assembly. The sleeve assembly includes a proximal ring, a distal ring, and a sleeve defining a passage therethrough. The base member includes an annular body including a coupling member. The annular body defines an opening in communication with the passage of the sleeve, and a circumferential groove configured to support the proximal ring of the sleeve assembly. The sealing assembly includes an annular frame and a seal dimensioned to cover the opening of the base member in a sealing relation. The coupling member of the base member releasably secures the sealing assembly to the base member. The annular frame of the sealing assembly is configured to be in registration with the annular body of the base member such that the proximal ring is interposed between the base member and the sealing assembly.

         4 . The method according to  claim 2 , wherein placing the proximal ring of the sleeve assembly includes placing the proximal ring in the circumferential groove of the annular body having adjacent lips defining a gap therebetween. 
     
     
         5 . The method according to  claim 2 , wherein placing the proximal ring of the sleeve assembly includes placing the proximal ring in the circumferential groove of the annular body having the lips disposed radially inwards of the proximal ring of the sleeve assembly. 
     
     
         6 . The method according to  claim 2 , wherein placing the proximal ring of the sleeve assembly includes placing the opening of the annular body in communication with a passage of the sleeve. 
     
     
         7 . The method according to  claim 2 , wherein placing the sealing assembly in registration with the annular body includes placing an annular frame of the sealing assembly in registration with the annular body such that the proximal ring is interposed between the annular body and the sealing assembly. 
     
     
         8 . The method according to  claim 2 , further including releasably securing the sealing assembly with the annular body. 
     
     
         9 . The method according to  claim 8 , wherein releasably securing the sealing assembly with the annular body includes hingedly coupling the sealing assembly with the annular body. 
     
     
         10 . The method according to  claim 8 , wherein releasably securing the sealing assembly with the annular body includes placing a hook of an annular frame of the sealing assembly into an aperture defined in the annular body. 
     
     
         11 . The method according to  claim 10 , wherein placing the hook of the annular frame of the sealing assembly includes placing the hook that is deflectable into the aperture of the annular body such that the hook is selectably movable through the aperture. 
     
     
         12 . The method according to  claim 2 , wherein placing the sealing assembly includes placing the sealing assembly that is formed of gel or silicone in registration with the annular body. 
     
     
         13 . The method according to  claim 2 , wherein placing the proximal ring of the sleeve assembly includes placing the proximal ring having a kidney-shaped cross-section in the circumferential groove of the annular body. 
     
     
         14 . The method according to  claim 2 , wherein rolling the sleeve of the sleeve assembly includes rolling the sleeve about the proximal ring. 
     
     
         15 . A method of accessing an internal body cavity comprising:
 positioning a sleeve assembly at least partially in the internal body cavity;   rolling a sleeve of the sleeve assembly such that proximal and distal portions of the sleeve assembly engage an outer epidermal tissue and an internal peritoneal wall of tissue, respectively;   placing a proximal ring of the sleeve assembly in a circumferential groove defined in a base member;   placing a sealing assembly in registration with the base member such that a body portion of a seal of the sealing assembly covers an opening defined in the base member in a sealing relation, and an overhang of the seal extending radially outwards from the body portion of the seal engages the proximal ring of the sleeve assembly;   releasably securing the sealing assembly with the base member; and   introducing an object into the internal body cavity through the sealing assembly.
