摘要：
An apparatus including a housing, and a suction control valve. The housing forms a handle and a shaft, where the shaft extends from the handle. The housing defines a suction channel from a distal end of the shaft. The suction control valve is connected to the suction channel at the handle. The suction control valve includes a valve body having a first channel and a second channel connected to the first channel, where the first channel forms a portion of the suction channel； and a valve barrel rotatably connected to the valve body. The valve barrel includes a rotatable ring extending around the handle and forming a portion of the housing. The ring includes an orifice configured to be rotated into and out of registration with an end of the second channel as the ring is rotated about the valve body, where at least a portion of the orifice has a non-circular cross section, and where the orifice has a first section with a general circular cross section and a second section with general slot shape.
