摘要：
A surgical instrument for use in connection with a pneumatically powered tool having a firing mechanism operably supported therein that is movable between an unactuated position and an actuated position. A pneumatically powered drive system operably communicates with the pneumatically powered tool and is configured to selectively apply at least a firing force to the firing mechanism of the pneumatically powered tool of sufficient magnitude to cause the firing mechanism to move from the unactuated position to the actuated position in response to a flow of gas from a source of gas that is fluidically coupled to the pneumatically powered drive system. At least one feedback device communicates with the pneumatically powered drive system for providing feedback concerning at least one of: (a) the magnitude of the firing force as the pneumatically powered drive system moves the firing mechanism from the unactuated to actuated position and (b) a relative position of the firing mechanism as the firing mechanismis moved between the unactuated and actuated positions.一種搭配一氣動工具使用的外科器具,該氣動工具有一可操作地支承於其內的擊發機構,該擊發機構可在一未作動位置與一已作動位置之間移動。一氣動傳動系統可操作地與該氣動工具聯繫且經建構用以回應一來自流體耦合於該氣動傳動系統之一氣體源的氣體流向該氣動工具擊發機構選擇性地施加夠強的至少一擊發力以導致該擊發機構從該未作動位置移到該已作動位置。至少一回饋裝置與該氣動傳動系統聯繫以提供有關以下至少一者之回饋:(a)該擊發力在該氣動傳動系統將該擊發機構從該未作動位置移往該已作動位置之過程中的量;及(b)該擊發機構當該擊發機構在該未作動位置與該已作動位置之間移動時之一相對位置。10...外科釘合及切斷器具12...終端作用器100...長軸桿總成104...樞軸200...活節控制器300...把手總成302...閉合扳機310...擊發扳機320...右邊機殼構件330...左邊機殼構件340...主殼體部分342...握把部分612...選擇開關
