A surgical tool set for treating a collapsed lung condition employs a trocar (20), and a nested cannula including a pleural port tube (30) and a fluid suction tube (50). In operation, the trocar (20) is nested within the pleural port tube (30), and utilized to puncture a port into a pleural cavity (10) of the patient while securing the pleural port tube (30) within the port. Subsequent to removing the trocar (20) from the pleural port tube (30), a fluid suction tube (50) is advanced with a fixed orientation through the secured pleural port tube (30) in a direction of a pleural cavity (10) target location (15) and air is suctioned from the pleural air space through one or more perforated holes into the fluid suction tube (50). The fluid suction tube (50) may have a target orientation section (42) or an additional target orientation tube (40) may be used to fix the orientation of the fluid suction tube (50) relative to the pleural port tube (30). |
