摘要：
The present application provides a surgical instrument with an electric drive clamping mechanism, comprising a clamping arm and an electric drive clamping mechanism, wherein the electric drive clamping mechanism comprises a moving component, a static component and a driving component； the surgical instrument is characterized in that: the driving component comprises a magnetizing body and a magnetized body； one of the magnetizing body and the magnetized body is connected with the moving component, and the other one is connected with the static component； the moving component is connected with the clamping arm； the magnetizing body generates a magnetic force when current is connected, the direction and degree of the magnetic force can be changed by changing current direction and degree； the magnetized body is attracted or repelled by the magnetic force generated by the magnetizing body, thereby driving the moving component to get close to or keep far away from the static component and further driving the clamping arm to close or open. The surgical instrument with the electric driving clamping mechanism and a surgical system can dynamically adjust the clamping force upon the using condition so as to reach better cutting and coagulating effects； and compared with the prior art, the surgical instrument has the advantages of simple structure and low cost, can be applied to a robot operation as a terminal executor, and is convenient in operation, and good for large-scale popularization and promotion.
