Anti-clog suction tip apparatus and methods
Various forms of anti-clog suction tips apparatus are disclosed. An exemplary anti-clog suction tip apparatus includes a suction tip assembly having a suction tip with a suction opening at a first end thereof for removing debris through suction, a hose attachment portion for attaching the suction tip assembly to a suction source, and an ejection wire channel. The apparatus further includes an ejection wire assembly having an ejection wire extending within the channel and an ejection button integral with or connected to the ejection wire. Applying a force to the ejection button advances the ejection wire through the channel such that an end portion of the ejection wire enters the suction tip and dislodges debris clogging the suction tip. The ejection wire may include an enlarged end portion such as, for example a ball tip. One or more of the components of the apparatus may be single-use and disposable.
1. A suction tip apparatus, comprising:
(a) an ejection wire located within a stylet passage, which stylet passage opens into a suction channel of the suction tip apparatus;
(b) an inner member comprising a shaft defining part of the suction channel;
(c) an outer member extending around and mounted on the inner member for sliding movement along the inner member, the ejection wire being connected to the outer member for movement concurrent with sliding of the outer member on the inner member; and
(d) a slider that is part of the outer member and accessible on an exterior of the suction tip apparatus, the slider being manually operable to slide the outer member on the inner member and move the ejection wire within the stylet passage toward a suction opening of the suction channel.
2. The suction tip apparatus of claim 1 , further comprising a biasing spring biasing the outer member in its slidable disposition over the inner member.
3. The suction tip apparatus of claim 1 , further comprising a handle portion, wherein the handle portion defines a vacuum tunnel having a vacuum tunnel opening located on a side of the handle portion, on which side the slider is accessible.
4. The suction tip apparatus of claim 3 , wherein the vacuum tunnel opening is located on a top side of the suction tip apparatus.
5. The suction tip apparatus of claim 3 , wherein the vacuum tunnel opens into the suction channel proximate a distal end of the shaft.
6. The suction tip apparatus of claim 1 , further comprising a handle portion, wherein the inner member is located within an interior of the handle portion.
7. The suction tip apparatus of claim 6 , further comprising a biasing spring biasing the outer member in its slidable disposition over the inner member.
8. The suction tip apparatus of claim 7 , wherein the spring extends around the shaft.
9. A method of clearing debris from a surgical site, comprising the steps of:
(a) attaching a suction tip apparatus to a suction source for the removal of debris through suction applied at a suction opening of a suction tip of the suction tip apparatus, the suction tip apparatus comprising,
(i) an ejection wire located within a stylet passage, which stylet passage opens into the suction channel of the suction tip apparatus,
(ii) an inner member comprising a shaft defining part of the suction channel,
(iii) an outer member extending around and mounted on the inner member for sliding movement along the inner member, the ejection wire being connected to the outer member for movement concurrent with sliding of the outer member on the inner member, and
(iv) a slider that is part of to the outer member and accessible on an exterior of the suction tip apparatus, the slider being manually operable to slide the outer member on the inner member and move the ejection wire within the stylet passage toward the suction opening of the suction channel;
(b) activating the suction source for applying suction at the suction opening of the suction tip;
(c) placing the suction tip near the debris causing the debris to be suctioned into the suction opening of the suction tip; and
(d) transitioning the ejection wire, whereby debris clogging the suction tip may be expelled from the suction opening.
10. The method of claim 9 , further comprising biasing the outer member in its slidable disposition over the inner member with a spring.
11. The method of claim 10 , wherein the spring extends around the shaft.
12. The method of claim 9 , further comprising a handle portion, wherein the handle portion defines a vacuum tunnel having a vacuum tunnel opening located on a side of the handle portion, on which side the slider is accessible.
13. The method of claim 12 , wherein the vacuum tunnel opening is located on a top side of the suction tip apparatus.
14. The method of claim 12 , wherein the vacuum tunnel opens into the suction channel proximate a distal end of the shaft.
15. The method of claim 9 , further comprising a handle portion, wherein the inner member is located within an interior of the handle portion.
16. The method of claim 15 , further comprising biasing the outer member in its slidable disposition over the inner member with a spring.
17. The method of claim 16 , wherein the spring extends around the shaft.
