Abstract

The invention provides a nail cartridge for an intracavity cutting anastomat, and the nail cartridge for the intracavity cutting anastomat solves the technical problems of poor anastomosis effect, more bleeding and high surgery risk in the existing ail cartridge for the intracavity cutting anastomat; the nail cartridge for the intracavity cutting anastomat is provided with a nail cartridge body, the nail cartridge body is provided with a cutting slot and suture nail slots, the nail cartridge body is also provided with a first tissue contacting surface and a second tissue contacting surface, wherein the first tissue contacting surface is located in the middle of the nail cartridge body in transverse direction, the second tissue contacting surface is located on the outside of the first tissue contacting surface; the second tissue contacting surface is higher than the first tissue contacting surface by 0.35mm, the suture nail slots are arranged in the first tissue contacting surface and the second tissue contacting surface, and the nail cartridge for the intracavity cutting anastomat can be widely used for intracavity cutting anastomats.

Description

technical field [0001] The invention relates to a medical device, in particular to a staple cartridge for an intracavity cutting stapler. Background technique [0002] At present, endovascular cutting staplers have been widely used in a variety of open or minimally invasive general surgery, obstetrics and gynecology, urology, thoracic surgery and pediatric operations. To clamp or flip tissue, you need to hold the closing handle to close the jaws when entering, and open the jaws to operate after entering. [0003] During the operation, the staples are driven into the tissues that have been aligned and need to be anastomosed together. After passing through the tissues, the staples are blocked by the anti-staple seat on the opposite side, and bend inward, forming a "B" that is misaligned with each other. shape to permanently staple tissue together. Since small blood vessels can pass through the gaps of the "B"-shaped staples, it does not affect the blood supply of the suture ...
