1. A suction tip apparatus for use during surgical procedures for the removal of debris from a surgical site, the apparatus comprising: (a) a suction tip at a distal end of the apparatus, the suction tip having a suction opening at a distal end thereof and having a suction channel for the removal of debris through suction applied at the suction opening, (b) a hose attachment portion at a proximal end of the apparatus for attachment to a suction source, (c) a handle portion for handling of the apparatus, the handle portion being located between the suction tip and the hose attachment portion, (d) an ejection wire channel extending from a distal end of the handle portion and opening into the suction channel of the suction tip proximate the suction opening of the suction tip, (e) an ejection wire that is transitionable between a retracted position and an advanced position such that, (i) when the ejection wire is in the retracted position, the ejection wire is retained within the ejection wire channel and does not obstruct suctioning of debris through the suction channel of the suction tip, and (ii) when the ejection wire is in the advanced position, the ejection wire extends from the ejection wire channel through the suction channel of the suction tip to the suction opening (f) a spring element that biases the ejection wire toward the retracted position, and (g) a manually operated control located on the handle portion for transitioning the ejection wire from the retracted position to the advanced position in opposition to the spring bias while handling the apparatus, whereby debris clogging the suction tip may be removed.
2. The suction tip apparatus of claim 1, wherein the ejection wire channel extends from the handle portion to the suction tip.
3. The suction tip apparatus of claim 1, wherein the manually operated control comprises an ejection tab, wherein manually depressing the ejection tab transitions the ejection wire from the retracted position to the advanced position in opposition to the spring bias.
4. The suction tip apparatus of claim 1, wherein the handle portion comprises a vacuum tunnel opening, and wherein the manually operated control is located on the same side of the handle portion as the vacuum tunnel opening.
5. The suction tip apparatus of claim 1, wherein the ejection wire is removably attached to the apparatus.
6. The suction tip apparatus of claim 5, wherein the handle portion defines a threaded opening by which the ejection wire is attached.
7. The suction tip apparatus of claim 1, wherein the ejection wire comprises a cable.
8. The suction tip apparatus of claim 1, wherein the spring element returns the ejection wire to the retracted position from the advanced position when the manually operated control ceases acting in opposition to the spring bias.
9. The suction tip apparatus of claim 4, wherein the manually operated control is located between the vacuum tunnel opening and the distal end of the handle portion.
10. The suction tip apparatus of claim 1, wherein the handle portion is plastic.
11. The suction tip apparatus of claim 1, wherein the ejection wire occupies the ejection wire channel.
12. The suction tip apparatus of claim 3, wherein the distal end of the ejection wire does not extend more than three millimeters beyond the suction opening when the ejection wire is fully advanced by depression of the ejection tab.
13. The suction tip apparatus of claim 3, wherein the ejection tab extends within a threaded opening of the handle portion.
14. The suction tip apparatus of claim 3, wherein the ejection tab is manually depressible in a direction that is angled toward the distal end of the handle portion.
15. The suction tip apparatus of claim 14, wherein the ejection tab is located behind a proximal end of the ejection wire relative to the direction of depression of the ejection tab.
16. The suction tip apparatus of claim 1, wherein the manually operated control comprises a plunger that has a press head and that is depressible in a direction angled toward the distal end of the handle portion.
17. The suction tip apparatus of claim 16, wherein the plunger extends within a threaded opening of the handle portion.
18. The suction tip apparatus of claim 16, wherein the press head of the plunger is located behind a proximal end of the ejection wire relative to the direction of depression of the plunger.
19. The suction tip apparatus of claim 18, wherein the distal end of the ejection wire does not extend more than three millimeters beyond the suction opening when the ejection wire is fully advanced by depression of the plunger.
20. A suction tip apparatus for use during surgical procedures for the removal of debris from a surgical site, the apparatus comprising: (a) a suction tip at a distal end of the apparatus, the suction tip having a suction opening at a distal end thereof and having a suction channel for the removal of debris through suction applied at the suction opening, (b) a hose attachment portion at a proximal end of the apparatus for attachment to a suction source, (c) a handle portion for handling of the apparatus, the handle portion being located between the suction tip and the hose attachment portion, (d) an ejection wire channel extending from a distal end of the handle portion and opening into the suction channel of the suction tip adjacent the suction opening of the suction tip, (e) an ejection wire that is transitionable between a retracted position and an advanced position such that, (i) when the ejection wire is in the retracted position, the ejection wire is retained within the ejection wire channel and does not obstruct suctioning of debris through the suction channel of the suction tip, and (ii) when the ejection wire is in the advanced position, the ejection wire extends from the ejection wire channel through the suction channel of the suction tip to the suction opening, and (f) a spring loaded control located on the handle portion for transitioning the ejection wire from the retracted position to the advanced position, wherein debris clogging the suction tip may be removed while handling the apparatus by manually actuating the control against the spring loading.
