    摘要： There are provided pressurized surgical instruments for use in pressurized surgical environments. The pressurized surgical instruments include pressurizing systems for maintaining a neutral or positive pressure flow within the surgical instrument during use. The pressurizing systems include a primary sensor for detecting the pressure of the surgical environment and a pressurizing mechanism for balancing the pressure of the surgical instrument with the surgical environment. The pressurizing mechanism includes a controller to receive and compare the signal sent from the primary sensor to the ambient or internal instrument pressure and a pressure delivery system to provide positive pressure to the interior of the surgical instrument in response to a signal received from the controller. The sources of pressure for the pressure delivery systems may be external or self contained within the surgical instrument.

    摘要： The present disclosure provides for a surgical instrument which includes a housing and an endoscopic portion extending distally from the housing and defining a first longitudinal axis. The surgical instrument also includes an end effector disposed adjacent a distal portion of the endoscopic portion. The end effector includes an anvil assembly and a cartridge assembly. The anvil assembly is pivotally coupled to the cartridge assembly to be movable from a first actuation position to at least one other second actuation position. The surgical instrument further includes a firing rod having a shaft defining a second longitudinal axis, the shaft having a cam member which is in mechanical cooperation with the anvil assembly and is configured to move the anvil assembly from the first actuation position to the at least one other second actuation position upon rotation of the firing rod about the second longitudinal axis.
