A gas exhaust valve for a surgical tool guider port, and more particularly, a gas exhaust valve for a surgical tool guider port for promptly releasing toxic gases or smoke generated during the surgical process through a simple one-touch manipulation of pushing a button, thereby improving the convenience of use and enabling a smooth endoscopic surgery, compared to a conventional gas exhaust port used during surgery. ## Claims ### Claim 1 An endoscopic surgical tool guider port installed in a surgical puncture site of a patient during an endoscopic surgery to safely guide various surgical tools introduced into a tube body through a tool introduction port provided at an upper portion into an abdominal cavity, the endoscopic surgical tool guider port comprising: an extraction bag formed in the tube body for containing and preserving extractions made during surgery, wherein the extraction bag protrudes to an outside. ### Claim 2 (depends on 1) The endoscopic surgical tool guider port of claim 1, wherein the extraction bag has a lower end hanging downward from an entrance of the extraction bag. ### Claim 3 (depends on 1) The endoscopic surgical tool guider port of claim 1, wherein a plurality of independent storage chambers divided by partitions for separating and preserving extractions are formed within the extraction bag. ### Claim 4 A gas exhaust valve for a surgical tool guider port installed in a surgical puncture site of a patient during an endoscopic surgery to guide various surgical tools into an abdominal cavity, the gas exhaust valve comprising: a valve body fixedly installed in an exhaust tube of the surgical tool guider port and having a gas passageway; a packing member for closing or opening the gas passageway while being attached to or separated from the valve body; and an actuating member for separating the packing member from the valve body when an external force is applied thereto, or for attaching the packing member to the valve body again when the external force is removed. ### Claim 5 (depends on 4) The gas exhaust valve of claim 4, wherein the actuating member comprises: a rod member bi-directionally protruding by passing through the valve body, the packing member being coupled to one of protruding ends of the rod member; a button member formed at the remaining end of the protruding ends of the rod member for moving the rod member forwards when an external force is applied thereto; and a resilient member installed within the valve body for moving the rod member backwards when the external force is removed by providing a resilient restoring force to the rod member. ### Claim 6 (depends on 4) The gas exhaust valve of claim 4, wherein a body head attached to an end of the exhaust tube when being inserted into and fixed to the exhaust tube protrudes from an outer surface of one end of the valve body. ### Claim 7 (depends on 4) The gas exhaust valve of claim 4, wherein the packing member is formed of a silicon material having a predetermined resiliency. ### Claim 8 (depends on 2) The endoscopic surgical tool guider port of claim 2, wherein a plurality of independent storage chambers divided by partitions for separating and preserving extractions are formed within the extraction bag. ### Claim 9 (depends on 5) The gas exhaust valve of claim 5, wherein the packing member is formed of a silicon material having a predetermined resiliency. ### Claim 10 (depends on 6) The gas exhaust valve of claim 6, wherein the packing member is formed of a silicon material having a predetermined resiliency.
