The burden to doctor can be increased, so need to provide a kind of simple to operate, and the medical care precess apparatus of precise structure.
The content of the invention
Goal of the invention：It is an object of the invention to solve to need to be accomplished manually operation in present cutting tissue operation, it is multiple
Miscellaneous and big to the mental burden of doctor problem.
Technical scheme：The present invention provides technical scheme below：A kind of cutting tissue circular staplers, including gun shaped body,
The gun shaped body includes barrel portion and handle portion, and the muzzle of barrel portion is provided with anastomat head plate, and anastomat head plate is towards gun shaped
There is the hollow straw extended at body side center, in the tissue containing cavities of hollow straw afterbody insertion barrel portion；The gun barrel
Hydraulic means is provided with the close handle portion in portion, hydraulic means includes hydraulic cylinder, has been able to the piston advanced in hydraulic cylinder, it is living
Plug is provided with a piston rod that the convenient promotion piston outside barrel portion is extended to through barrel portion away from the side of anastomat head plate,
Expansion link is fixed with piston, expansion link is fixed with circular cutter away from the top of barrel portion.
Used as optimization, the expansion link includes at least two cracking connecting rods, has the screw hole being mutually adapted on two sections of connecting rods, makes to stretch
Contracting bar can be fixed after flexible.
Used as optimization, the anastomat head plate is installed on the head of hollow straw, and anastomat head plate center has can allow sky
The installing hole that heart suction pipe exposes.
Used as optimization, the tissue containing cavities are connected with negtive-pressure implement.
Used as optimization, the hydraulic means is provided with the oil conservator connected with hydraulic cylinder near one end of anastomat head plate.
Operation principle：The tissue size cut off according to needed for operation, chooses the anastomat head plate of designated diameter, then basis
The size of anastomat head plate, the length of adjustable telescopic rod so that the air line distance of circular cutter to anastomat head plate center with coincide
The radius error of device head plate is less than 1mm, the tissue of excision needed for anastomat head plate is posted by, and being slowly advanced piston rod makes
Piston is obtained along barrel portion axially-movable until the tissue of excision needed for circular cutter is propped up, in slow rotation piston rod piston edge is caused
Barrel portion is rotated, and tissue is cut off.
Beneficial effect：The present invention is relative to prior art：Because the waste motion of hand influences whether the accurate of cutting tissue
Property, and it is very high for the requirement of doctor accurately to perform the operation, that is, allow to perform an operation, institute also very big for the mental burden of doctor
With using the design of the present invention, by the operation of this part, the operation of machinery is converted to so that obtain the characteristics of the high precision of machinery
Play；By the way of hydraulic drive circular cutter so that it is slow that the speed of propulsion becomes, position more accurate.
