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, and the tissue of excision, detains trigger so that ring needed for anastomat head plate is posted by
Cutting knife gets at tissue and tissue can be cut off, and rotation rounded ring body completes excision operation, after the completion of excision, opens negative pressure
Device so that tissue containing cavities form negative pressure, and the tissue of excision is taken in tissue containing cavities automatically by hollow straw.
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；There is the arc of depression towards the direction of hollow straw from the one end away from hollow custom using the anastomat head plate is increased
Degree, is the skin and non-flat forms or parts of lesions tissue projection due to partial portion, can be right using flat anastomat head plate
Tissue produces extruding causes pathology, therefore is preferably fitted skin using cambered anastomat head plate, while anastomat head plate is remote
Soft silicone glue-line is provided with from the side of handle portion, the water content of resection organization needed for increasing occurs hydration, required excision
Tissue soften, it becomes possible to preferably sucked by hollow straw.
