ABSTRACT:
A system, method and apparatus for regulating vacuum applied to surgical suction devices allowing the use of a single vacuum regulator and associated canister to provide vacuum to two suction devices, such as a suction stabilizer and a suction retractor. Vacuum controllers may be placed in the vacuum lines provided to each of two or more suction devices, or may be placed only in the vacuum line of the suction device believed most likely to detach during the procedure. Each vacuum controller is provided with a primary vacuum line, coupling its associated suction device to the output of the vacuum regulator and a pilot passage, also coupling the suction device to the vacuum regulator. The controller closes a valve in the main vacuum line in response to loss of vacuum attachment, which valve remains closed until attachment is reestablished. Closure of the valve results in substantial or complete blockage of the main vacuum line. The pilot passage, which may be part of the valve or a separate vacuum line, serves to allow reestablishment of vacuum attachment while the valve is closed. The pilot passage is configured so that airflow through the pilot passage is low enough that the other suction device or devices coupled to the vacuum regulator can still maintain vacuum attachment.
