a gas orifice disposed in the tube portion of the main body between the wash orifice and the distal end of the main body, and configured to allow the pressurized gas to flow toward the cavity, the gas orifice including a raised elevation relative to an adjacent portion of a wall of the main body; and
a fluid orifice disposed in the tube portion of the main body adjacent the wash orifice and configured to receive fluid from the cavity.
2. The trocar of claim 1 , further comprising a fluid channel coupled between a fluid inlet port and the wash orifice to provide fluid communication there between.
3. The trocar of claim 1 , further comprising a fluid channel coupled between a gas inlet port and the gas orifice to provide fluid communication there between.
4. The trocar of claim 1 , further comprising a wash channel coupled between a fluid inlet port and the wash orifice to provide fluid communication therebetween and a gas channel coupled between a gas inlet port and the gas orifice to provide fluid communication therebetween, wherein at least a portion of the gas channel is parallel to a portion of the wash channel.
5. The trocar of claim 1 , wherein the distal end of the tube portion of the main body comprises a shaped end having a first edge and a second edge opposite the first edge, wherein the first edge extends further from the head portion than the second edge.
6. The trocar of claim 1 , wherein the wash orifice comprises an angled port formed through at least part of the tube portion of the main body.
7. The trocar of claim 1 , wherein the gas orifice comprises an angled port formed through at least part of the tube portion of the main body.
8. The trocar of claim 1 , further comprising one or more seals disposed adjacent the cavity and configured to seal against a portion of the endoscope while the endoscope is disposed in the cavity.
9. The trocar of claim 8 , wherein the one or more seals comprise a lip seal.
10. The trocar of claim 8 , wherein the one or more seals are disposed between the gas orifice and the wash orifice.
11. The trocar of claim 8 , wherein the one or more seals are disposed adjacent the wash orifice and spaced from the gas orifice.
12. The trocar of claim 1 , further comprising one or more vent apertures formed through the main body.
13. The trocar of claim 12 , further comprising a protrusion formed on the main body and extending inwardly into the cavity, wherein the protrusion is disposed adjacent the one or more vent apertures.
14. An intraoperative endoscope cleaning system comprising:
the trocar of claim 1 ;
a control unit configured to control a flow of fluid to the trocar;
a wash solution reservoir in fluid communication with the wash orifice; and
a gas supply in fluid communication with the gas orifice.
15. The trocar of claim 1 , wherein the gas orifice is a first gas orifice, and the trocar further comprises:
a second gas orifice disposed in the tube portion of the main body adjacent the wash orifice and configured to allow the pressurized gas to flow toward the cavity and to atomize at least a portion of the wash solution in the cavity.
16. The trocar of claim 15 , wherein the second gas orifice is configured to cause a higher gas flow distally than the gas flow proximally.
17. The trocar of claim 1 , further comprising a wash channel coupled between a fluid inlet port and the wash orifice to provide fluid communication therebetween and a gas channel coupled between a gas inlet port and the gas orifice to provide fluid communication therebetween, wherein at least a portion of the gas channel is shaped to surround at least a portion of the wash channel.
18. The trocar of claim 17 , further comprising one or more third gas orifices disposed in communication with the gas channel.
19. A method for cleaning an endoscope during a procedure, the method comprising utilizing a trocar, the trocar including:
a main body comprising an elongate hollow tube portion extending terminating at a distal end, wherein the tube portion defines a cavity configured to receive an endoscope;
a wash orifice disposed in the tube portion of the main body and configured to allow the wash solution to flow toward the cavity;
a gas orifice disposed in the tube portion of the main body between the wash orifice and the distal end of the main body, and configured to allow the pressurized gas to flow toward the cavity, the gas orifice including a raised elevation relative to an adjacent portion of a wall of the main body; and
a fluid orifice disposed in the tube portion of the main body adjacent the wash orifice and configured to receive fluid from the cavity;
the method comprising:
washing the endoscope;
drying the endoscope; and
managing residual fluids on the endoscope or in the cavity, or both.
20. The method of claim 19 , wherein the managing residual fluids comprises using physical seals to compartmentalize the wash solution during the washing and drying phases of the method.
21. The method of claim 19 , wherein the managing residual fluids comprises using suction to extract residual wash solution that ingresses the trocar during the washing and drying phases of the method.
22. The method of claim 19 , wherein the managing residual fluids comprises using rear gas pressure to prevent wash solution ingress during the washing and drying phases of the method.
23. The method of claim 19 , wherein the managing residual fluids comprises using a rear gas seal to prevent wash solution ingress during the washing and drying phases of the method.
24. The method of claim 19 , wherein the managing residual fluids comprises using vents to passively allow wash solution to pass out of the trocar during the washing and drying phases of the method.
25. The method of claim 19 , wherein the managing residual fluids comprises using drains and ribs to passively allow wash solution to pass out of the trocar during the washing and drying phases of the method.
