Suction capability in neurosurgery is a critical tool utilized to clear the field and improve visualization of anatomical structures. It is also used for fragmentation and debulking of pathological tumor masses [1]. Prior to the Frazier cannula, there was no orifice bent pressure relief valve associated with suction; this tool provides independent dual suction force [2]. The Frazier cannula has the capability to reach absolute suction or zero suction instantaneously [3]. In this article, we introduce a new concept, how to obtain zero suction with the Frazier orifice bent pressure relief valve without any equipment modification. This technique is obtained by decreasing the suction value to 10 mmHg of Mercury per the vacuum pressure monitoring gage while removing the surgeon's finger from the orifice pressure relief valve.
