Staple cartridge component and medical anastomat using staple cartridge

Abstract

The invention provides a staple cartridge component and a medical anastomat using the staple cartridge component, wherein the staple cartridge component comprises a staple cartridge connecting piece and a knife pushing rod, and further comprises a limiting block which is accommodated inside the staple cartridge connecting piece so as to limit the plurality of the thin sheets from mutually separating in the overlapping direction of the plurality of the thin sheets; the knife pushing rod is formed by overlapping a plurality of thin sheets; and in a process of triggering the knife pushing rod, the limiting block, following the knife pushing rod, moves towards the far end of the staple cartridge component from the near end of the staple cartridge component and constantly limits the plurality of the thin sheets from mutually separating in the overlapping direction of the plurality of the thin sheets. The staple cartridge component disclosed by the invention has the beneficial effects that the staple cartridge component is provided with the limiting block, and the limiting block moves along with the knife pushing rod at least in the process of triggering the knife pushing rod so as to constantly limit the plurality of the thin sheets; therefore, the plurality of the thin sheets of the knife pushing rod are prevented from mutually separating in the overlapping direction.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a staple cartridge assembly and a medical stapler using the staple cartridge assembly. Background technique [0002] A medical stapler is a medical device often used in surgery, and it is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of production technology, the medical staplers currently used in clinical practice are reliable in quality, easy to use, tight, and suitable for tightness, especially their advantages such as fast suturing, easy operation, and few side effects and surgical complications. It is favored and respected by clinical surgeons at home and abroad. [0003] At present, the pusher bar of a medical stapler can be composed of multiple thin slices, and the thickness of each slice is about 0.25mm. Since the slices are thin and elastic, the pusher bar composed of multiple slices will ...

AI Technical Summary

Problems solved by technology

In actual application, during the firing process of the medical stapler and when the pusher rod is bent, the multiple slices are subjected to a huge external force, which makes the multiple slices easy to deform or separate from each other in the direction of the stacking of multiple slices, which leads to the firing of the medical stapler.
