Abstract

The invention discloses a surgical instrument for traceless invisibility of a television endoscope surgery and a method thereof. The surgical instrument comprises handles (1) and an end head, wherein the handle (1) is in threaded connection with the end head or in a lock catch connection with the end head; the method comprises the following steps of: during an operation, inserting one or more handles (1) into a thoracic cavity or an abdominal cavity from a position favorable for assisting a main knife operator, and fixedly connecting an end head with the handle (1) in the thoracic cavity or the abdominal cavity through a main operation hole; the plurality of handles (1) are operated by an operation assistant by utilizing different functions of the end heads, and are matched with instruments of a main knife operator in the main operation hole to complete various operation steps.
