Disclosed are an anastomotic nail of a surgical anastomat and a combined forming groove. A nail anvil forming groove and a nail push block forming groove approach each other to form the combined forming groove. When the anastomotic nail is matched with tissues with various thicknesses, the distance between the nail anvil forming groove and the nail push block forming groove of the combined forming groove is continuously shortened, and two nail legs of the anastomotic nail are respectively bent to be helical along the combined forming groove with the continuously shortened distance to form a double helical anastomotic nail until the forming height of the anastomotic nail can meet the requirements of clamping thicknesses matched with the tissues with the various thicknesses. Therefore, to-be-matched tissues needing different clamping thicknesses can be matched without replacing a nail magazine containing anastomotic nails with different nail leg lengths.
Description
technical field [0001] The present invention relates to staples and their forming grooves used in various surgical staplers, in particular to staples and their forming grooves used in straight staplers or straight cutting staplers, and especially to arc cutting anastomosis Staples and their forming grooves used in circular staplers, especially staples and their forming grooves used in circular staplers, especially staples and their forming grooves used in laparoscopic surgical cutting staplers, and more In particular, it relates to staples and forming grooves thereof used in various electric surgical staplers. Background technique [0002] Various surgical staplers are used to replace the manual anastomosis operation with needles and threads in surgery, and are being widely used in end-to-end, end-to-side and side-to-side anastomosis operations of organs and tissues such as human digestive tract organs, respiratory tract organs, and urogenital organs. The operation of formi...
