Minimally invasive surgery inflow cannula device

A system, comprising:

• a powered hand-piece comprising a working end;
• a cutting tool operatively coupled to the working end of the powered hand-piece;
• and
• an irrigation system coupled to the working end of the powered hand-piece, the irrigation system comprising:
• a body defining a proximal portion and a distal portion, wherein the proximal portion defines a cavity sized and configured to receive a working end of a hand-piece therein, and wherein the distal portion defines a tool channel sized and configured to receive the cutting tool therethrough;
• an inlet tube extending through a portion of the body, the inlet tube configured to receive a fluid flow therethrough;
• an outlet tube assembly coupled to the distal portion of the body, wherein the outlet tube assembly extends at least partially through the tool channel, wherein the outlet tube assembly comprises:
• an inner tube;
• and
• an outer tube, wherein the inner tube and the outer tube define a fluid path therebetween,
• wherein the inlet tube is in fluid communication with the outlet tube assembly such that the fluid flow received through the inlet tube flows through the fluid path of the outlet tube assembly and exits the outlet tube assembly at a distal end, and wherein the distal end of the outlet tube assembly provides the fluid circumferentially about the tool.

A method, comprising:

• coupling an irrigation system to a powered hand-piece, wherein the irrigation system comprises:

• an inlet tube extending through a portion of the body;
• an outlet tube assembly coupled to the distal portion of the body, wherein the outlet tube assembly extends at least partially through the tool channel, wherein the outlet tube assembly comprises:
• an inner tube;
• and
• an outer tube, wherein the inner tube and the outer tube define a fluid path therebetween,
• wherein the inlet tube is in fluid communication with the outlet tube assembly;
• coupling a cutting tool to the powered hand-piece, wherein the cutting tool is received through a tool channel defined in the distal portion of the body;
• providing fluid flow to a distal end of the tool, wherein the fluid flow is provided through the inlet tube and the fluid path of the outlet tube assembly, and wherein the distal end of the outlet tube assembly provides the fluid circumferentially about the tool.
