    • Endoscopic apparatus is provided, having a distal end (102) for insertion into a body of a patient and a proximal end that is held outside the body of the patient. The apparatus includes a proximal cylinder (404), disposed in a vicinity of the proximal end of the endoscopic apparatus. A proximal piston (406) is slidably contained within the proximal cylinder. A distal cylinder (328) is disposed in a vicinity of the distal end of the endoscopic apparatus, and a distal piston (310) is slidably contained within the distal cylinder. A tube (402) for containing a liquid is coupled between the proximal and distal cylinders. A tool (e.g., biopsy tool 115) is coupled to be actuated by displacement of the distal piston, so as to perform a mechanical action on tissue of the body or contents of the body, responsive to displacement of the distal piston.
    • 提供内窥镜装置,其具有用于插入患者体内的远端(102)和保持在患者身体外部的近端。 该装置包括设置在内窥镜装置的近端附近的近端圆柱体(404)。 近端活塞(406)可滑动地容纳在近端气缸内。 远端圆筒(328)设置在内窥镜装置的远端附近,并且远侧活塞(310)可滑动地容纳在远端圆筒内。 用于容纳液体的管(402)联接在近端和远端圆筒之间。 联接工具(例如,活组织检查工具115)以通过远端活塞的移位来致动,以响应于远端活塞的位移对身体的组织或身体内容物进行机械作用。
