Surgical system and method of use

Abstract

A surgical system for use in establishing and maintaining an opening to an anatomical space of a body, the system comprising an obturator assembly having a cutting portion at a distal end and a cannula, the cannula being detachably coupled to the cutting portion and deployable into the anatomical space of a patient, the cannula comprises a locking portion, and a lengthwise extendable body; a valve assembly comprising a passage for receiving the cannula, a first end for coupling to a fluid extraction device and a second end for placement external and adjacent the anatomical space; a base comprising a plate for placement on a patient external and adjacent the anatomical space, the plate has an aperture configured for receiving the obturator assembly and coupling means located about the aperture for coupling with the valve assembly; and wherein, in use, the locking portion of the cannula is configured to be retained in the valve assembly with the extendable body extended into the anatomical space to facilitate a path for fluid extraction, and wherein the cannula comprises means for retaining the cannula in its extended state.

The claims defining the invention are as follows: 
     
         1 . A base which, in use, receives an obturator assembly for establishing and maintaining an opening to an anatomical space of a body, the base comprising a plate for placement on a patient external and adjacent the anatomical space, the plate having an aperture configured to receive the obturator assembly. 
     
     
         2 . A base which, in use, receives an obturator assembly for the treatment of simple and/or tension pneumothorax, comprising a plate for placement on a patient above an intercostal space, the plate having an aperture configured to receive the obturator assembly. 
     
     
         3 . A base according to  claim 1 , wherein an underside of the plate is provided with adhesive means for securing the plate to the patient. 
     
     
         4 . A base according to  claim 3 , wherein the adhesive means is foam-backed adhesive. 
     
     
         5 . A base according to  claim 1 , further comprising an indicator extending from the plate for assisting a user with placement of the plate external and adjacent or above the anatomical or intercostal space. 
     
     
         6 . A base according to  claim 1 , wherein the plate further comprises coupling means located about the aperture for receiving a valve assembly operable to seal the aperture in use. 
     
     
         7 . A base according to  claim 6 , wherein the coupling means is configured to receive the valve assembly at an angle inclined to an axis perpendicular to the plane of the plate. 
     
     
         8 . A base according to  claim 1 , further comprising side portions extending in opposite directions from the plate for stabilising the plate from movement when applied to the patient. 
     
     
         9 . A base according to  claim 1 , further comprising an electrode embedded in the plate configured for outputting physiological data to an external monitoring device.
