The invention discloses an arc-shaped cutting anastomat, which comprises an upper bracket plate, a lower bracket plate, a nail pressing seat bracket, an arc-shaped cutting assembly, a positioning rod push rod, a resetting button, a movable hand shank, a hand shank shell, a nail pressing seat and a push rod hand shank arranged on the tail part of the positioning rod push rod, wherein the nail pressing seat is arranged on the nail pressing seat bracket; the arc-shaped cutting assembly is fixedly connected with the positioning rod push rod; the upper bracket plate and the lower bracket plate arefixedly connected with the hand shank shell; the arc-shaped cutting assembly and the positioning rod push rod are movably inserted between the upper bracket plate and the lower bracket plate; and theupper bracket plate, the lower bracket plate and the nail pressing seat bracket are integrated with one another to form an integrated structure. According to the arc-shaped cutting anastomat, the upper bracket plate, the lower bracket plate and the nail pressing seat bracket are integrated with one another to form the integrated structure, so that a staggering phenomenon caused by riveting the upper bracket plate, the lower bracket plate and the nail pressing seat bracket is avoided; therefore, the precision of a circular arc is guaranteed, and the intensity of the whole anastomat is improved.
Description
technical field [0001] The invention relates to an arc cutting stapler, which belongs to the field of medical instruments. Background technique [0002] At present, the upper and lower support plates and the anvil support of the existing arc-shaped cutting stapler are riveted by riveting pins, so that the upper and lower support plates and the anvil support are all arcs. shape, so riveting is quite difficult, and riveting is also prone to misalignment, causing the center of the arc to not be on the same central axis, which affects the accuracy of the arc and the overall strength of the stapler. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an arc-shaped cutting stapler that can not only ensure the accuracy of the arc but also increase the strength of the stapler. [0004] The technical solution to realize the object of the present invention is: an arc-shaped cutting stapler, which inclu...
