Lock-switch 9.
During the use of intracavitary Endo-GIA, doctor can grasp tissue quilt at any time by observing the position of cutter
The position of cutting and state, make surgical procedure safer.Often there are cutter and retracted not in existing intracavitary Endo-GIA
In place, jaw is opened, and departs from jaw and again during clamp in tissue, the cutting edges of cutter be likely to will tissue cutting by mistake,
Cause unnecessary damage.In addition, when loading nail bin, it may appear that suturing nail is pushed out too early in nail bin, and cause apparatus has
Effect cutting stitch length shortens, and easily causes tissue damage, increases operation risk, and bring greatly operation wind to patient
Danger.
The content of the invention
The present invention is turned on so as to produce to solve jaw when the cutter of existing intracavitary Endo-GIA retract not in place
A kind of a series of technical problem of raw risks, there is provided chamber that can ensure that only jaw could be opened when cutter are retracted in place
Internal cutting stapler detects protection device with cutter withdrawing.
The technical scheme is that including solve lock-switch, unlock switch shaft, withdrawing swing rod and torsion spring, withdrawing swing rod
