Above-mentioned purpose is to be achieved by below scheme: the percussion actuating device of intralumenal anastomosis device, including fixed handle, firing handle, left plate and the right panel of composition firing handle are separately mounted to the left and right sides at middle part on front side of fixed handle by connecting pin, connecting pin is connected with fixed handle by connecting pin spring, it is left right with fan tooth that the upper limb of left plate and right panel is respectively arranged with fan tooth, it is provided with tooth bar on fixed handle between a fan tooth left side and the fan tooth right side, tooth bar front end is connected with push rod, drive the gear wheel of tooth bar by gear wheel pin be arranged on that the left and little gear of two side pinion around is right to be connected, instruction block it is provided with on the left of gear wheel pin, right side is provided with spring, a little gear left side is engaged with travelling gear, travelling gear is left with sector to be engaged, the little gear right side is right with fan tooth engages.
The radius that the radius of described travelling gear is right more than the left and little gear of little gear.
Operation principle
When the percussion actuating device of the present invention and intracavity Endo-GIA support the use, after the clamp tissue of stitching will be cut, firing handle is pulled to carry out firing action, now gear wheel pin be instructed to that block props up can only be with little gear is right and gear wheel effect, sector right belt is moved the little gear right side and is rotated backward, little gear is right 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 sewing process of tissue completes.
Unclamping firing handle, now gear wheel pin is only with gear wheel effect, and sector is left and the fan tooth right side is connected pin and springs return initial position.
Again pull firing handle, now gear wheel pin is under the action of the spring with a little gear left side and gear wheel effect, sector left band nutating gear rotates backward, travelling gear rotates before driving little gear left-hand, and little gear is left drives gear wheel to rotate forward under the effect of gear wheel pin, gear wheel band carry-over bar rearward movement, rack drives push rod, push jack, cutter rearward movement, when firing handle holds root, whole fallback action completes, and cutter return to initial position.
Unclamping firing handle, now gear wheel pin is only with gear wheel effect, and sector is left and the fan tooth right side is connected pin and springs return initial position.
Knowable to above-mentioned operation principle, the percussion actuating device of the present invention has only to shot during whole, a fallback action can complete, and closes firing handle during operation for twice, and step is simple, easy to use.
