Surgical operating instrument and guiding assembly and disassembling tool thereof

According to the surgical operating instrument and the guiding assembly and the disassembling tool thereof, the guiding assembly comprises a body part and a movable limiting part, the body part comprises a joint part and a guiding part, the movable limiting part comprises a sliding clamping part, and the movable limiting part is used for enabling the joint part and the tail end of an actuator assembly to be switched between a separation state and a joint state. An operator can meet the operation requirement only through one surgical operation instrument with the guiding assembly, another instrument does not need to be started, and therefore medical cost and expenses can be reduced easily. When the movable limiting piece is subjected to acting force in the joint direction, the movable limiting piece is subjected to non-flexible deformation under abutting of the sliding guide part, and the non-flexible deformation is released when the movable limiting piece slides to the joint position so that the movable limit
