Emitted on the alignment pin provided with reset, the reset, which emits, left rotation and right rotation and to drive left reseting plate and right reset on alignment pin
Piece alternately and repeatedly moves up and down, and drives rollback ratchet and percussion ratchet alternately and repeatedly to move up and down, and rollback ratchet and percussion
Ratchet is able to alternately and repeatedly engage with the rollback tooth of two-way ratchet and advance tooth.
In the present invention, the percussion ratchet of traditional Endo-GIA is not only provided with, and rollback ratchet is set on trigger, and
Rollback tooth corresponding to being set on corresponding two-way ratchet, and by left reseting plate on two-way ratchet and right reseting plate and by fixed
The synergy that resets of the position pin connection on left reseting plate and right reseting plate emits realize rollback ratchet and percussion ratchet and time
The alternately and repeatedly engagement of tooth and advance tooth is moved back, so as to make the present invention only need a hand can to realize cutting in operation
The feed of stapler and withdrawing.
Wherein, in order that rollback ratchet is connected more stable with trigger, rollback connecting rod rack, rollback connecting rod rack are also set up
On be also cased with rollback ratchet torsion spring and rollback connecting rod；Rollback ratchet is connected on trigger by rollback connecting rod rack.Wherein retract
Connecting rod increases the stability of structure, and rollback ratchet torsion spring is arranged between rollback ratchet and trigger, there is provided rollback ratchet is pressed against
Rollback tooth and rollback ratchet power required when returning.
Wherein, in order to provide percussion ratchet extruding advance tooth and fire power required when ratchet is carried out, percussion spine is also set up
Pawl torsion spring, the percussion ratchet torsion spring are arranged on be connected position of the percussion ratchet with trigger.
Wherein, in order to increase the security of mechanism, percussion safety device is additionally provided with two-way ratchet.
Wherein, in order that the singlehanded more convenient operation of the present invention, reset is emitted and is arranged to detachable block, and is set
Put the rearmost end in left reseting plate and right reseting plate.So in one hand in use, reset only, which need to be pinned, with thumb emits left-right rotary
Turn that work can be completed.
Wherein, the reset, which emits, is additionally provided with limited block.
Beneficial effect：The present invention compared with prior art, has the advantages that：The present invention not only has tradition cutting
The cutting of stapler, which coincide, to be acted on, and can not needed under another hand or other people assistance in withdrawing, singlehanded complete
Into tool backlash movement, and the withdrawing bar of traditional Endo-GIA is eliminated, the present invention is taken up space smaller, simple to operate, peace
It is complete reliable and stable, it is possible to reduce to the secondary injury of human body.
