摘要：A surgical instrument utilized in a minimally invasive surgery is provided. The surgical instrument includes an end effecter configured to conduct a surgical operation, a piezoelectric driver configured to generate motive power, a power transmitting unit configured to transmit the motive power generated by the piezoelectric driver to the end effecter to operate the end effecter, and a housing which encloses the power transmitting unit and the at least one piezoelectric driver.
主权项：1. A surgical instrument comprising: at least one end effecter configured to conduct a surgical operation; at least one piezoelectric driver configured to generate motive power; a power transmitting unit configured to transmit the motive power generated by the at least one piezoelectric driver to the at least one end effecter to operate the at least one end effecter; and a housing which encloses the power transmitting unit and the at least one piezoelectric driver wherein the at least one piezoelectric driver comprises a pair of piezoelectric elements that are spaced apart from each other, a pair of elastic bodies fixed to the respective piezoelectric elements and spaced apart from each other, and a coupling tip which connects the elastic bodies and is in contact with the power transmitting unit.
