Technical Field
The utility model relates to the technical field of high-frequency electrotomes, in particular to a high-frequency electrotome negative plate impedance monitor.
Background
The high frequency electric knife is an electric surgical instrument for cutting tissues instead of a mechanical surgical knife. The argon high-frequency electrotome heats the body tissue when contacting with the body through the high-frequency high-voltage current generated by the tip of the effective electrode, thereby realizing the separation and solidification of the body tissue and achieving the purposes of cutting and hemostasis. The high frequency electrotome negative plate (NE) is an electrode having an instant area for connection to the patient's body and is intended to provide a return path of low current density for high frequency current to prevent the high frequency current from producing undesirable physical effects of burns in human tissue.
The negative plate is usually composed of more than two pieces of conductive parts, and is usually fixed on the muscle tissue of the human body by adopting an adhesive mode when in use. The current conventional monitoring method is to add an alternating current driving signal to two conductive parts of the negative plate, and then obtain information related to contact quality through an alternating current impedance measuring circuit, so as to obtain a required result. The monitoring circuit generally comprises circuits for generating driving signals, coupling, rectifying and detecting feedback signals and the like, and sends the monitoring signals to the high-frequency electrotome controller. Because the monitoring circuit and the high-frequency working current act on the negative plate simultaneously, the voltage and the resistance of the negative plate are not monitored timely enough. The voltage and resistance of the negative plate cannot be monitored rapidly.
