    摘要: A method for collecting and filtering biological material from blood and other fluids during a surgical procedure includes: attaching a first cover including a suction port and an intake port to a collection trap; attaching a suction source to the suction port; attaching an instrument to the intake port, through which blood and tissue are suctioned and received into the collection trap; filing the collection trap with blood and tissue; removing the collection trap from the first cover; attaching a second cover to the collection trap in place of the first cover, the second cover including a suction port and a plunger, the plunger including a press head having a screen portion permitting blood and other fluids to pass; attaching a suction source to the suction port of the second cover; separating the blood from the tissue by deploying the plunger; and drawing off the blood through the suction port.

    摘要: 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.
