Method for operating an electrical surgical instrument with optimal tissue compression
First Claim
1. A method of configuring a surgical instrument having a surgical tissue-compressing device including opposing compression surfaces with a tissue-compression-measuring mechanism, the method comprising:
- providing a switching element having first and second switching states changed solely by mechanical movements;
mechanically coupling the switching element with a biasing element retaining the switching element in one of the first and second switching states until a pre-determined force is imparted to the switching element, the pre-determined force being an amount of force proportional to an optimal tissue compression force of compressed tissue disposed between the opposing compression surfaces; and
positioning the switching element in line with the surgical tissue-compressing device to cause the pre-determined force, proportional to a force placed upon compressed tissue disposed between the opposing compression surfaces, to be placed upon the switching element.

10. A method for configuring a surgical instrument having a surgical tissue-compressing device including opposing compression surfaces with a tissue compression-measuring mechanism, the method comprising:
-
providing a switching element having first and second switching states changed solely by mechanical movements; mechanically coupling the switching element with a biasing element imparting a pre-determined force on the switching element to retain the switching element in one of the first and second switching states until a switching force at least as great as a force imposed by the biasing element is imparted to the switching element and causes a change of the switching state to occur, the switching force being an amount of force proportional to an optimal tissue compression force of compressed tissue disposed between the opposing compression surfaces; and positioning the switching element in line with the surgical tissue-compressing device to cause an amount of force, proportional to the force placed upon compressed tissue disposed between the opposing compression surfaces, to be placed upon the switching element. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
