This invention is about a kind of Spring-striking Mechanism for Endoscope Attachment’s Application. This striking mechanism consists of an outer shell, cover body, bottom cap, driver assembly, buffering assembly and spring pipelines. A putter inside the spring pipelines is connected to a sensor. The driver assembly has a striking spring and a restoring spring. The two springs are set with different degree of rigidity forming the striking apparatus’ reciprocating mechanism. Through the restoring spring’s elasticity, the striking spring recompresses to its striking length after the striking mechanism’s sensor is emitted. The restoring motion can be done at a single driving point hence the striking operation can be done using one hand. This can simplify doctor’s operation to enhance convenience and efficiency.本發明係有關於一種應用於內視鏡附件之彈簧式擊發機構,該擊發機構包含外殼、蓋體、底蓋、驅動組件、緩衝組件以及彈簧管線,並於彈簧管線內設一連接有感測器之推桿,其中,該驅動組件具有一擊發彈簧及一復位彈簧,並使兩彈簧具不同程度之剛性,以構成該擊發裝置之往復結構,藉此,使擊發機構之感測器擊發後,能透過復位彈簧之彈力將擊發彈簧重新壓縮至擊發長度,而能以單一驅動點完成復位動作,並能單手完成擊發之操作,進而簡化醫生操作動作,提高便利性與效率。1‧‧‧擊發機構2‧‧‧外殼21‧‧‧外嵌垣22‧‧‧內嵌垣23‧‧‧固定座3‧‧‧蓋體4‧‧‧底蓋42‧‧‧管線51‧‧‧按壓裝置511‧‧‧觸發桿512‧‧‧凸垣52‧‧‧拉桿521‧‧‧凸塊53‧‧‧復位彈簧54‧‧‧扳機541‧‧‧彈性撐桿55‧‧‧擊發彈簧61‧‧‧座體611‧‧‧貫通孔612‧‧‧凸塊62‧‧‧緩衝彈簧7‧‧‧彈簧管線71‧‧‧推桿8‧‧‧金屬導線9‧‧‧感測器
