Abstract:
An apparatus and method to suppress vacuum surges in a surgical aspiration system is disclosed and claimed. A vacuum surge suppressor includes a first fluid path for coupling to a surgical instrument, and a filter attached to the first fluid path. A flow restrictor is coupled to the filter with the filter disposed upstream of the flow restrictor. The vacuum surge suppressor also includes a second fluid path for coupling to a vacuum pump. The second fluid path is connected to the flow restrictor and disposed downstream of the flow restrictor. The second fluid path defines a path internal pressure. A third fluid path is coupled to the filter and is connected to the second fluid path, bypassing the flow restrictor. A valve in the third fluid path obstructs flow in the third fluid path in response to the path internal pressure.
