Surgical probe adapted for smoke evacuation

A valved device adapted for controlling flow into or out from a surgical patient, said valved device comprising:

• a body defining a flow passageway;
• a valve connected to said body for flow communication with said flow passageway, said valve comprising a barrel and a piston extending into said barrel;
• said piston being mounted for selectively displacing said piston longitudinally within said barrel in a direction along the axis of said barrel to select primary passage flow into or out of said surgical patient;
• and
• said piston also being mounted to occupy a longitudinal position in said barrel wherein said means for selective rotational movement can be accomplished independent of said axial movement between a radial position with respect to said barrel in which secondary flow is prevented and a rotated radial position with respect to said barrel in which secondary flow is permitted, wherein said secondary flow is selectively permitted or prevented, all without further axial displacement of said piston in said barrel.

A valved device adapted for controlling flow into or out from a surgical patient, said valved device comprising:

• a body defining a flow passageway;
• a valve connected to said body, said valve comprising a barrel mounted to said body for flow communication with said flow passageway defined in said body, a port defined in said barrel for flow into or out from said barrel, and a piston extending into said barrel and mounted for selective longitudinal movement in a direction along an axis of said barrel and for selective rotational movement in a direction about said axis of said barrel;
• means forming a primary flow path through said valve between said flow passageway defined in said body and said port defined in said barrel upon said selective longitudinal movement of said piston along said axis of said barrel;
• and
• means forming a substantially separate secondary flow path through said valve between said flow passageway and said port upon said selective rotational movement of said piston about said axis of said barrel,
• said piston being mounted to occupy a longitudinal position in said barrel wherein said piston is rotatable to selectively prevent or allow flow through said secondary passage without further axial displacement of said piston in said barrel.

• wherein said piston is mounted to occupy a longitudinal position in said barrel wherein said piston may be rotated to allow or prevent said secondary flow independently of axial movement of said piston;
• and
• a seal positioned to prevent flow out from said barrel through a port when said piston is in said radial position and to permit flow out from said barrel when said piston is in said rotated radial position;
• wherein said seal is oriented at an angle to a plane perpendicular to said axis of said barrel, and wherein selective rotational movement of said piston causes a potion of said seal to traverse a portion of said port.
