ASPIRATION IRRIGATION DEVICE FOR LAPAROSCOPIC SURGERY
A suction-irrigiation aspiration device may be provided with a tip capable of mechanical action to break up or emulsify material into smaller particles during a suction or irrigation procedure. The mechanical action in the tip may the in the form of a rotational or linear reciprocating motion to cut or emulsify the blood or tissue and thereby prevent or reduce clogging of the suction-irrigiation aspiration device.

a reciprocating suction-irrigation aspiration tip subassembly;
a suction-irrigation valve subassembly; and
a motor subassembly.
2 . The aspiration irrigation device of claim 1 , further comprising a valve to shaft coupling with outer tube subassembly.
3 . The aspiration irrigation device of claim 2 , wherein the valve to shaft coupling with outer tube subassembly includes an outer shaft with a 3.0 mm diameter.
4 . The aspiration irrigation device of claim 1 , a motor to valve coupling with inner tube subassembly.
5 . The aspiration irrigation device of claim 1 , wherein the reciprocating suction-irrigation aspiration tip subassembly includes a rotary or rotary reciprocating tip.

8 . The aspiration irrigation device of claim 5 , wherein the rotary or rotary reciprocating tip is provided with two or more openings on a distal face of the rotary or rotary reciprocating tip.
9 . The aspiration irrigation device of claim 8 , wherein the two or more openings are defined by an elongated circular or crescent-shaped slot or cutout.
10 . The aspiration irrigation device of claim 5 , wherein the rotary or rotary reciprocating tip is configured to rotate intermittently between a clockwise and a counter-clockwise direction.
11 . The aspiration irrigation device of claim 1 , wherein the reciprocating suction-irrigation aspiration tip subassembly includes a linear reciprocating tip.
12 . The aspiration irrigation device of claim 11 , wherein the linear reciprocating tip has an outer diameter of 5.0 mm to 6.0 mm.
13 . The aspiration irrigation device of claim 11 , wherein the linear reciprocating tip is provided with two or more openings on a distal face of the linear reciprocating tip.
14 . The aspiration irrigation device of claim 13 , wherein the two or more openings are defined by an elongated circular or crescent-shaped slot or cutout.
15 . The aspiration irrigation device of claim 11 , wherein the linear reciprocating tip is provided with two or more lateral openings provided on a circumferential surface of linear reciprocating the tip.
16 . The aspiration irrigation device of claim 1 , wherein the suction-irrigation valve subassembly includes a suction control valve.
17 . The aspiration irrigation device of claim 16 , wherein the suction control valve is attached to a suction source via a tube.
18 . The aspiration irrigation device of claim 17 , wherein the suction source is a portable suction pump or a hospital suction system.
19 . The aspiration irrigation device of claim 1 , wherein the suction-irrigation valve subassembly includes an irrigation control valve.
20 . The aspiration irrigation device of claim 19 , wherein the irrigation control valve is attached to a fluid IV source or a pumping system.
