Problems solved by technology
In order to achieve such a surgical effect, as described in U.S. Patent Publication 20070194082, it is necessary to install U-shaped staples with different staple leg heights in the same staple cartridge, or distribute forming grooves with different depths on the same anvil, or place the staples The anvil and the staple cartridge are made into a stepped shape, and the staples and their forming grooves of this style of surgical stapler increase the difficulty of processing and installation of the instrument, thereby increasing the cost of the instrument

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 used in various surgical staplers and their forming grooves, in particular to staples and forming grooves used in straight staplers or straight cutting staplers, and particularly to arc-shaped cutting anastomoses The staples and their forming grooves used in the instrument, especially the staples and their forming grooves used in the circular stapler, and the staples and their forming grooves used in the endoscopic surgical cutting stapler, more In particular, it relates to staples used in various electric surgical staplers and their forming grooves. Background technique [0002] Various surgical staplers are used to replace the needle and thread anastomosis in surgical operations. They are being widely used for end-to-end, end-to-side and side-to-side anastomosis of human digestive tract organs, respiratory organs, urogenital organs and other organs and tissues. Channel forming surgery, closed incision surgery and ...
