As a key component of endoscopic stapler, the fastener assembly plays a vital role in minimally invasive surgery, which is directly related to the success or failure of surgery and the prognosis of patients.
From the appearance of the structure, the nail base is usually round or oval, its surface design is fine, with a certain arc to better fit the human tissue. A number of card slots are arranged around the assembly for installing the anastomosis nails. The card slots are arranged in an orderly manner and the spacing is uniform, which accurately corresponds to the position of the anastomosis nails, ensuring that the anastomosis nails can be accurately positioned during the surgical operation to achieve efficient and accurate anastomosis. In order to facilitate coordination with the main body of the stapler, the pin holder is also equipped with a connection structure, such as a special interface, a buckle, etc., which can be closely connected with the rod body to ensure that there will be no loosening, displacement and other conditions in the complex endoscopic surgery environment, and the stable transmission of operating instructions.
