Abstract: The present disclosure provides a multiple-processing device for an endoscope. The multi-processing device may comprise a plurality of processing units, a conveying component, and an operation component. The processing units may include a capsule body and clamping arms. A proximal end of the capsule body may be provided with a first limit part that may be available for deformation or failure under an external force. The distal end of a conveying pipe of the conveying component and/or the proximal end of the capsule body may be provided with a second limit part configured to expand and contract along a radial direction of the conveying pipe.
