The specific embodiment
With reference to accompanying drawing 1～3, the percussion actuating device 11 of disposable linear anastomat comprises percussion contiguous block one 11-2, percussion contiguous block two 11-4, percussion push pedal 11-6 and percussion contiguous block back-moving spring 11-7, the end of percussion contiguous block one 11-2 is movably connected in assembly train wheel bridge 1 and assembly lower plate 6-1 rear end by contiguous block pin one 11-1, the percussion contiguous block one 11-2 other end flexibly connects with the end of percussion contiguous block two 11-4 by contiguous block pin three 11-3, percussion contiguous block back-moving spring 11-7 is housed on contiguous block pin three 11-3, and the other end of percussion contiguous block two 11-4 is by contiguous block pin two 11-5 and nail supporting base train wheel bridge 1, nail supporting base lower plate 6-1 rear portion flexibly connects.Described percussion push pedal 11-6 is contained in the flexible handle 9.
Operation principle: during the supporting use of the percussion actuating device 11 of disposable linear anastomat and disposable linear anastomat, at first, the stationary positioned bar slide block that promotes percussion insurance institution 5 forward drives locating rod, locating rod is adorned in the locating rod jack that is inserted on the nail supporting base 2, again safety block is opened, push flexible handle 9, flexible handle 9 lower ends press percussion contiguous block one 11-2, percussion contiguous block two 11-4, percussion contiguous block one 11-2 and percussion contiguous block two 11-4 drive assembly clamping plate assembly 4, in nail supporting base train wheel bridge 1 and nail supporting base lower plate 6, slide mobile, the tissue that coincide so just can be adjusted to best seam between nail bin groupware 3 and nail supporting base assembly 2, the position coincide, to organize clamping, unclamp flexible handle 9, once more by depressing flexible handle 9, the indication push pedal is withstood in percussion push pedal 7 in the flexible handle 9, the indication push pedal promotes nail pushing plate 4-4, nail pushing plate 4-4 promotes pushing slice of nail the anastomosis staple penetrate tissue is formed the B font, to organize seam, kiss, drive indicator collet 8 to form hole 10-1 simultaneously, indication seam when seeing indicator collet 8, the operation of kiss tissue is finished.
Promote SR 7, SR plate 7 ejects percussion push pedal and percussion contiguous block one 11-2, percussion contiguous block two 11-4, percussion contiguous block one 11-2, percussion contiguous block two 11-4 are automatically reset, drive assembly clamping plate assembly 4 and reset to initial condition, nail supporting base 2 is separated into initial condition with nail bin 3, slide to the back with stationary positioned bar slide block and drive locating rod backward this moment, and insurance resets, and apparatus is taken out from seam, the tissue that coincide.
