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. In various embodiments, a drive system operably communicates with the pneumatically powered tool and is configured to selectively apply at least a drive system generated firing motion to the firing mechanism of the pneumatically powered tool 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 fluidically coupled to said drive system. A retraction member communicates with the drive system to enable a manually generated retraction motion to be applied thereto to manually move the firing mechanism in a distal direction from the actuated position to the unactuated position.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。在各實施例中,一傳動系統與該氣動工具可操作地聯繫,且經建構用以選擇性地施加至少一傳動系統產生的擊發運動至該氣動工具擊發機構以導致該擊發機構從該未作動位置移到該已作動位置以回應一來自流體耦合於該傳動系統之一氣體源的氣體流。一回縮構件與該傳動系統聯繫以讓一手動產生的回縮運動能夠施加於該傳動系統,藉此手動地使該擊發機構依一近側方向從該已作動位置移到該未作動位置。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
