10. A bendable endoscopic linear cutting anastomat apparatus, comprising a handle and a bendable endoscopic linear cutting anastomat assembly connected to a front end of the handle, wherein the bendable endoscopic linear cutting anastomat assembly comprises:
an anastomat jaw, a turning connection block, an assembly inner core, a cutting blade assembly, a left and right bending sheet comprising a left side and a right side connected by a bending part; and a push-pull rod; wherein the assembly inner core comprises an inner core shell and an inner core connection block fixedly mounted in the inner core shell;
wherein a front end of the turning connection block is hinged to a rear end of the anastomat jaw, a first vertical rotation shaft is located at a first hinge to provide a first vertical rotation axis, a rear end of the turning connection block is hinged to a front end of the inner core connection block, a second vertical rotation shaft is located at a second hinge to provide a second vertical rotation axis, the cutting blade assembly penetrates through the inner core connection block, the turning connection block and the anastomat jaw, and is configured to slide forwards and backwards;
wherein the left side or the right side of the left and right bending sheet is connected to a front end of the push-pull rod, and is configured to drive the anastomat jaw to bend left and right around the first vertical rotation axis and the second vertical rotation axis under the push-pull action of the push-pull rod as the bending part slides around the inner core connection block.
