When tissue is clamped between the moving plate 41 and the staple abutting seat 22, the staples 211 are fired to pass through the group, the end parts of the two sides of the staples 211 enter the staple abutting grooves 221, the end parts of the staples 211 are bent under the limitation of the arc-shaped groove bottoms of the staple abutting grooves 221, and finally the end parts of the staples pass through the tissue and are bent on the other side of the tissue, so that part of the tissue is clamped by the staples 211 and is fired sequentially through the plurality of staples 211 to anastomose the tissue.

Further, referring to fig. 15, a placement groove 321 is formed on the pushing block 32, and a portion of the staple 211 away from the end is disposed in the placement groove 321.

When the pushing block 32 pushes the staples 211 to move, the staples 211 are not prone to tilting, so that the staples 211 can accurately enter the bending groove 43 or the staple abutting groove 221 to be bent, and the staples 211 are more stable.

Further, the staple outlet holes 212 and the staples 211 are matched with each other, when the staples 211 are unfired, the staples 211 are disposed in the staple outlet holes 212, and the staple outlet holes 212 limit the staples 211 from tilting, so that the staples 211 cannot tilt in the staple outlet holes 212 and in the staple outlet holes 212.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some technical features, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
