device for endoluminal or laparoscopic grasp a tissue sample from the body and cut of a patient

摘要

A surgical device for endoluminally or laparoscopically grasping and excising a target tissue (1) sample from areas in a patient's body comprises a surgical stapling device (4) having a distal staple fastening assembly (5) connected via one or more flexible force transmitters (25) to a proximal handle, wherein the staple fastening assembly (5) comprises a cartridge device (8) containing one or more curved open rows of staples as well as a knife, a curved anvil (7) having a staple forming face adapted to cooperate with the cartridge device (8) to form the ends of the staples expelled from the cartridge device (8). The anvil (7) is movable with respect to the cartridge device (8) along a longitudinal axis (L) of the staple fastening assembly (5) and the staple fastening assembly (5) is curved about the longitudinal axis (L). A lateral end of the anvil (7) and a corresponding lateral end of the cartridge device (8) are connected by a longitudinally extending lateral shaft (9) so that a substantially C shaped frame is formed which defines a window (6) for receiving the target tissue (1) and a lateral opening (10) opposite the lateral shaft (9) configured to provide lateral access to the window (6).
