Deflection detection structure, control method of deflection detection structure, electric anastomat and medical equipment

Abstract

The invention provides a deflection detection structure, a control method of the deflection detection structure, an electric anastomat and medical equipment, wherein the deflection detection structure is applied to detection of a deflection action of an operation end of the medical equipment and comprises a driving part, an interface part and a detection part; the driving part is used for executing a rotating action so as to provide a driving force for realizing the deflection action of the operation end; the interface part is in transmission connection with the driving part and is used for converting the rotation action of the driving part into a linear movement action along the axial direction; and the detection part is arranged on the interface part and is used for detecting the moving position of the linear movement action of the interface part relative to a supporting part along the axial direction so as to complete the detection of the deflection action. Therefore, on the premise of mechanical limiting, electronic limiting position detection is added; a jaw assembly can stop deflection before impacting the mechanical limiting when executing deflection operation; and deflection impact is effectively prevented.

Description

technical field [0001] The disclosure relates to the technical field of medical devices, in particular to a deflection detection structure and a control method thereof, an electric stapler and medical equipment. Background technique [0002] After the existing electric stapler enters the human body, the front jaw assembly needs to be able to deflect, so that the staple cartridge can contact lesions at different positions and angles to complete the operation. However, due to the narrow operating space in the human body and the limited field of view, there may be problems such as collisions with internal tissues and organs during the deflection process or discontinuous deflection angles, resulting in failure to reach the location of the lesion. In mild cases, the operation cannot be effectively completed, and in severe cases, organ damage is caused, which expands the scope of the operation. . Moreover, the deflection of the front jaw assembly of the existing electric stapler ...

Problems solved by technology

However, due to the narrow operating space in the human body and the limited field of view, there may be problems such as collisions with internal tissues and organs during the deflection process or discontinuous deflection angles, resulting in failure to reach the location of the lesion. In mild cases, the operation cannot be effectively completed, and in severe cases, organ damage is caused, which expands the scope of the operation.

Moreover, the deflection of the front jaw assembly of the existing electric stapler has a maximum angle limit, but due to the precision of the mechanical structure, it is difficult to effectively set the limit mechanism, so that the deflection of the jaw assembly of the stapler tends to exceed the maximum use angle, resulting in cutting or stapling energy. Insufficient or even the cutting knife breaks, expanding the scope of surgery and causing serious secondary injuries to the patient
