4. The electrical yaw failure remedy device according to claim 3, characterized by manual rotation of the swivel head (7) bringing the intermediate gear (4) into rotational motion, whereby manual yaw is achieved by bringing the yaw linkage (8) back and forth via the yaw screw (9) and the yaw nut (6).
5. The electric steering failure remedy device according to claim 1, characterized in that the intermediate gear (4) is fixedly connected with the steering screw (9), the steering screw (9) is in threaded fit with the steering nut (6), the steering nut (6) is provided with a steering nut protrusion (62), the steering link (8) is provided with a steering link hole (81), and the steering nut protrusion (62) is in fit connection with the steering link hole (81).
6. The electrical yaw failure remediation device of claim 2 further comprising a manual yaw gear (3), the rotating head (7) meshing with the manual yaw gear (3), the intermediate gear (4) meshing with the manual yaw gear (3).
7. The device for remedying the failure of the electric bending according to claim 6, wherein when the electric bending of the electric stapler fails, the rotary head (7) is manually driven to move forwards or backwards, so that the internal teeth (71) of the rotary head are engaged with the manual bending gear (3), and the rotary head (7) is engaged with the intermediate gear (4) through the manual bending gear (3) to realize the manual bending.
8. The device for remedying the failure of the electric bending according to claim 6, further comprising an internal gear (5), wherein the internal gear (5) is fixedly connected with the rotating head (7), when the electric bending of the electric anastomat fails, the rotating head (7) is manually driven to move forwards or backwards to enable the rotating head (7) to be meshed with the manual bending gear (3) through the internal gear (5), and meanwhile, the forward or backward movement of the rotating head (7) drives the motor gear (2) to move forwards and backwards to be disengaged from the intermediate gear (4), so that the manual bending is realized.
9. The electrical yaw failure remedy device according to claim 8, characterized in that the inner gear (5) is provided with inner gear protrusions (51), the rotary head (7) is provided with rotary head grooves (73), and the inner gear (5) is fittingly connected with the rotary head grooves (73) of the rotary head (7) through the inner gear protrusions (51).
10. A motorized stapler, characterized in that it comprises a motorized flexion failure remedy according to any one of claims 1 to 9.
