Abstract
(EN)
The utility model provides a closing driving mechanism and a medical anastomat comprising the same. Wherein the closing driving mechanism comprises a first sliding block, a maintaining piece, a closing driving piece and a pushing block, the first sliding block is connected with the closing driving piece, the first sliding block comprises a first embedding part, the maintaining piece comprises a second embedding part and a first lifting part which are connected, and the pushing block comprises a second lifting part located below the first lifting part. When the nail head part of the anastomat is closed; the first embedding part of the first sliding block is positioned below the second embedding part of the retainer; the first embedding part is embedded with the second embedding part; underthe action of the retaining piece; the closing driving piece is kept at the closing position; after the anastomat is fired, the push block is lifted upwards, the second lifting part of the push blocklifts the first lifting part of the retainer upwards, the second embedding part is lifted upwards to be separated from the first embedding part, the closing driving part loses the retaining effect ofthe retainer and can move towards the far end side, and therefore the nail head part is opened.
