Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0025] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0026] The present application will be further described below with reference to the drawings and specific embodiments, but is not limited to the present application.

[0027] EMBODIMENT

[0028] The present embodiment provides an anastomat not easy to be mistaken, comprising: a staple cartridge base 1, a sleeve part 2 connected to the proximal end of the staple cartridge base, and a driving part arranged at the proximal end of the sleeve part 2.

[0029] The staple cartridge base 1 comprises: an anvil abutting seat 11, a staple cartridge base 12 hingedly connected to the proximal end of the anvil abutting seat 11, and a staple cartridge assembly 13 detachably connected to the staple cartridge base 12.

[0030] The proximal end of the staple cartridge base 12 is limited by two inwardly protruding limiting blocks 111 on the inner walls on both sides, and the proximal end of the staple cartridge assembly 13 is limited; a through groove 121 is formed in the middle of the staple cartridge base 12 for sliding of the cutting part 21.

[0031] The staple cartridge assembly 13 comprises a staple cartridge body 131, a pusher block 132 slidingly arranged in the middle of the staple cartridge body 131, a staple cartridge holder 133 and a staple cartridge protective cover 134; the staple cartridge body 131 comprises two parallel arranged staple cartridges 1311 and a connecting portion 1312 connecting the two staple cartridges 1311; the distal end of the staple cartridge 1311 is fixedly connected with the proximal end of the connecting portion 1312; the bottom end of the staple cartridge 1311 is provided with a sliding groove along the length direction; the pusher block 132 comprises an insurance portion 1321 matched with the cutting portion 21 and pusher portions 1322 located on both sides of the insurance portion 1321; the pusher portions 1322 are slidingly arranged in the sliding groove of the bottom end of the staple cartridge 1311; the insurance portion 1321 is slidingly arranged between the two staple cartridges 1311; the plane where the proximal end of the insurance portion 1321 is located is parallel to and does not coincide with the plane where the proximal end of the pusher portion 1322 is located; the staple cartridge holder 133 and the staple cartridge protective cover 134 are arranged on both sides of the staple cartridge body 131 respectively.

[0032] The sleeve portion 2 is provided with a cutting portion 21 and a push rod driving the cutting portion 21 to perform linear reciprocating motion; the proximal end of the push rod extends to the driving portion and is driven by the driving portion to perform linear reciprocating motion.

[0033] The medical staff needs to install the staple cartridge assembly 13 on the cartridge base 12 first; when installing, the medical staff needs to pay attention to the installation direction; the staple cartridge holder 133 is in contact with the cartridge base 12, and the connecting portion 1312 is outside; the size of the staple cartridge assembly 13 matches the size of the cartridge base 12; because the inner walls on both sides of the proximal end of the cartridge base 12 are inwardly protruded to form limiting stoppers 111, the width of the proximal end of the cartridge base 12 is smaller than the width of the staple cartridge assembly 13, so that when the medical staff feels that the staple cartridge assembly 13 cannot be pushed inwardly, it indicates that the staple cartridge assembly 13 has been installed in place; after the installation is completed, the medical staff removes the staple cartridge protective cover 134, and then the subsequent operation can be performed; during the operation, the driving portion drives the push rod and then drives the cutting portion 21 to perform linear motion, the cutting portion 21 pushes the pusher block 132 to move forward and then realizes the cutting and anastomosis of the target portion.

[0034] In summary, the anastomat of the present application improves the cartridge base, makes the inner wall protrude to form limiting stoppers, limits the staple cartridge assembly, so that the staple cartridge assembly will not be installed excessively during operation, and avoids the mis-touching of the pusher block and the cutting portion; the present application also adjusts the size of the insurance portion in the middle of the pusher block, increases the safety distance between the insurance portion and the cutting portion, and cooperates with the limiting stoppers to avoid mis-touching.

[0035] The above merely describes preferred embodiments of the present application, and is not intended to limit the implementation and protection scope of the present application. For those skilled in the art, it should be understood that any equivalent substitutions and obvious changes made according to the content of the present application description and drawings should be included in the protection scope of the present application.
