Title:
DEFLECTION DETECTION STRUCTURE AND CONTROL METHOD THEREFOR, ELECTRIC STAPLER, AND MEDICAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/045562
Kind Code:
A1
Abstract:
A deflection detection structure and a control method therefor, an electric stapler, and a medical apparatus. The deflection detection structure is applied to the detection of a deflection action of an operating end of a medical apparatus, and comprises a driving portion, an interface portion, and a detection portion. The driving portion is used for performing a rotating action to provide a driving force for achieving the deflection action of the operating end; the interface portion is transmittingly connected to the driving portion, and used for converting the rotating action of the driving portion into a linear movement along the axial direction; and the detection portion is disposed on the interface portion, and used for detecting the movement position of the linear movement of the interface portion along the axial direction relative to a support portion, so as to complete the detection of the deflection action. Therefore, electronic limit position detection can be added while there is a mechanical limit, so that a jaw assembly can stop deflection before hitting the mechanical limit when performing a deflection operation, thereby effectively preventing deflection impact.
