The radius of described travelling gear is greater than the radius on a pinion left side and the pinion right side.
Operation principle
When percussion actuating device of the present invention and intracavity Endo-GIA support the use, will after the clamp tissue of cutting and stitching, firing handle is pulled to carry out firing action, now gear wheel pin be instructed to that block props up can only the right and gear wheel effect with pinion, sector right belt is moved the pinion right side and is rotated backward, the pinion right side drives gear wheel to rotate backward under the effect of gear wheel pin, gear wheel band carry-over bar travels forward, tooth bar promotes push rod, push jack, cutter, ejector pin block travels forward, when firing handle holds root, whole firing action completes, the cutting and stitching process of tissue completes.
Unclamp firing handle, now gear wheel pin is only with gear wheel effect, and a sector left side and the fan tooth right side are connected pin and springs return initial position.
Again pull firing handle, now gear wheel pin and gear wheel effect left with pinion under the action of the spring, the left band nutating gear of sector rotates backward, travelling gear rotates before driving pinion left-hand, and a pinion left side drives gear wheel to rotate forward under the effect of gear wheel pin, and gear wheel band carry-over bar moves backward, rack drives push rod, push jack, cutter move backward, when firing handle holds root, whole fallback action completes, and initial position got back to by cutter.
Unclamp firing handle, now gear wheel pin is only with gear wheel effect, and a sector left side and the fan tooth right side are connected pin and springs return initial position.
From above-mentioned operation principle, percussion actuating device of the present invention only needs shot in whole process, a fallback action can complete, and closes firing handle twice during operation, and step is simple, easy to use.
