Debrider with multiple flushing orifices

1. A surgical apparatus, comprising:

(a) a debriding device, which is fitted at a distal end of the surgical apparatus and is configured to debride tissue from a debriding site in a patient body;

(b) a hollow tube, configured to evacuate the debrided tissue away from the debriding site, wherein the hollow tube includes an inner surface; and

(c) an irrigation assembly, configured to apply irrigation fluid, via one or more orifices, to the debrided tissue being evacuated, the irrigation assembly comprising an elongate member, wherein an outer surface of the elongate member is fixably coupled to the inner surface of the hollow tube to prevent relative movement between the elongate member and the hollow tube, wherein the one or more orifices are formed in the elongate member,

wherein the one or more orifices comprise multiple orifices that are distributed along the elongate member, wherein the multiple orifices comprise at least first and second orifices, wherein the first orifice is configured to apply the irrigation fluid at a first irrigation angle, wherein the second orifice is configured to apply the irrigation fluid at a second irrigation angle that is different from the first irrigation angle, wherein the second irrigation angle is orthogonal to a longitudinal axis of the hollow tube.

2. The apparatus according to claim 1 , wherein each orifice is configured to regulate a selected irrigating pressure of the irrigation fluid delivered via the orifice.

3. The apparatus according to claim 1 , and comprising a suction assembly, which is configured to assist in evacuating the debrided tissue by applying vacuum along the hollow tube.

4. The apparatus according to claim 1 , wherein the first orifice is located closer to the debriding device than the second orifice, and wherein the irrigation assembly is configured to apply the irrigation via the second orifice to the debrided tissue that was previously irrigated via the first orifice.

5. The apparatus according to claim 4 , wherein the first irrigation angle is non-orthogonal to the longitudinal axis of the hollow tube.

6. The apparatus according to claim 1 , wherein the irrigation assembly is configured to determine a distribution of irrigating pressures of the irrigation fluid along the hollow tube.

7. The apparatus according to claim 1 , wherein the multiple orifices are arranged in a line.

8. The apparatus according to claim 1 , wherein the elongate member is an elongate tube that is configured to circumferentially surround the irrigation fluid, wherein the one or more orifices are formed in the elongate tube.

9. The apparatus according to claim 1 , wherein the hollow tube defines an internal lumen extending along a central axis, wherein the elongate member is laterally offset from the central axis within the internal lumen.

10. The apparatus according to claim 1 , wherein the elongate member and the hollow tube are non-concentric.

11. A surgical apparatus, comprising:

(a) a debriding device, which is fitted at a distal end of the surgical apparatus and is configured to debride tissue from a debriding site in a patient body;

(b) a hollow tube, configured to evacuate the debrided tissue away from the debriding site, the hollow tube defining an internal lumen extending along a central axis; and

(c) an irrigation assembly, configured to apply irrigation fluid, via one or more orifices, to the debrided tissue being evacuated, the irrigation assembly being positioned inside of the hollow tube, the irrigation assembly comprising an elongate tube that is laterally offset from the central axis within the internal lumen, wherein the elongate tube is configured to circumferentially surround the irrigation fluid, wherein the one or more orifices are formed in the elongate tube,

wherein the one or more orifices comprise multiple orifices that are distributed along the elongate tube, wherein the multiple orifices comprise at least first and second orifices, wherein the first orifice is configured to apply the irrigation fluid at a first irrigation angle, wherein the second orifice is configured to apply the irrigation fluid at a second irrigation angle that is different from the first irrigation angle, wherein the second irrigation angle is orthogonal to the central axis of the hollow tube.

12. The apparatus according to claim 11 , wherein the elongate tube and the hollow tube are non-concentric.

13. A surgical apparatus, comprising:

(a) a hollow tube configured to evacuate tissue away from a debriding site, wherein the hollow tube defines an internal lumen extending along a central axis;

(b) an elongate shaft disposed within the internal lumen, wherein the elongate shaft comprises a debriding device that is fitted at a distal end of the elongate shaft and is configured to debride the tissue from the debriding site in a patient body; and

(c) an irrigation assembly that includes an elongate tube that is laterally offset from the central axis within the internal lumen, the irrigation assembly being positioned inside of the hollow tube, wherein the irrigation assembly includes at least first and second orifices configured to apply irrigation fluid to the debrided tissue being evacuated, wherein the first orifice is configured to apply the irrigation fluid at a first irrigation angle, wherein the first irrigation angle is orthogonal to the central axis of the hollow tube.

14. The apparatus according to claim 13 , wherein the hollow tube is straight, wherein the central axis runs along the entire length of the hollow tube.

15. The apparatus according to claim 13 , wherein the first orifice located is closer to the debriding device than the second orifice, and wherein the second orifice is configured to apply the irrigation fluid to the debrided tissue that was previously irrigated via the first orifice.
