Abstract

The invention discloses a surgical fitting nail for kidney-shape forming and a forming groove thereof, wherein the forming groove is composed of a lateral face, a bottom face and a diagonal ridge which are formed by the forming groove inwards concave on the surface of a nail anvil; M-shaped fitting nails are used; the convex degree of the M-shaped fitting nails which are arranged on an inner ring or the near side of a cutter groove on the middle parts of nail beams are larger than that of the M-shaped fitting nails arranged on an outer ring or the far side of the cutter groove on the middle parts of the nail beams; thus, when the fitting nails with same heights are used for fitting fitted tissues with different thicknesses, the M-shaped fitting nails are bent on the forming groove by a nail pushing block so as to form a kidney-shaped fitting nail; therefore, the surgical fitting nail achieves beneficial surgical effect of closing, stanching the fitted tissues and healing peripheral tissues.

Description

technical field [0001] The present invention relates to surgical staples used in various surgical staplers and their forming grooves, in particular to surgical staples capable of kidney shape forming and their forming grooves. 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 channel-forming operation and the incision-closing operation are especially suitable for anastomosis of organs and tissues that are difficult to expose and operate, which can reduce operation time and improve operation quality. [0003] As introduced in US Patent Publications 20070194082 and 20090255978, the components of the staple forming mechanisms of various known surgical staplers mainly include: a sta...
