Disposable flat pad device in endoscope cutting anastomat nail bin assembly

Abstract

The invention discloses a disposable flat pad device in an endoscope cutting anastomat nail bin assembly. The device comprises a rubber tube shell assembled by a rubber tube S and a rubber tube L, therubber tube shell is internally provided with a basic block, a push cutter rod assembly and a flat pad device body, and the push cutter rod assembly is driven by the basic block to move forth and back in the axial direction of the rubber tube shell; the flat pad device body is composed of a plurality of flat pads symmetrically arranged at the two sides of the push cutter rod assembly, each flat pad is made of an elastic material and provided with an arc back part, a first hook pin, a second hook pin and a third hook pin, each first hook pin and the corresponding second hook pin are located atthe two ends of the corresponding back part and extend in the direction away from the corresponding back part, each third hook pin is located between the corresponding first and second hook pins, andthe first hook pins, the second hook pins and the third hook pins are clamped with through holes correspondingly formed in the rubber tube S respectively. Under the condition that when an existing anastomat is in use, the push cutter rod assembly is deformed due to swinging of the end part, and the flat pad device provides a deformed limiting channel, so that the swinging and firing process of the instrument is smoother.

Description

technical field [0001] The invention relates to the technical field of disposable laparoscopic staplers, in particular to a flat pad device in a staple cartridge assembly of a disposable laparoscopic cutting stapler. Background technique [0002] Since there is no device that can limit the deformation of the pusher rod assembly in the existing instrument rubber hose, the deflection of the instrument head will cause a large bending deformation of the pusher rod assembly in the rubber hose. Due to the thrust, the pusher rod assembly may be deformed. Wrinkled or damaged, making the instrument unusable. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a flat pad device in the staple cartridge assembly of a disposable laparoscopic cutting stapler, which can effectively limit the deformation of the pusher rod assembly without hindering the movement of the base block in the rubber tube. [0004] In order to solve the a...
