A high-frequency electrosurgical control system and its control method

Abstract

The invention relates to a high-frequency electrotome control system and a control method thereof. The control system includes an electric knife activation pedal, a master-slave control system and a high-frequency electrotome activation hardware arbitration module; Activate the hardware arbitration module from the control system and the high-frequency electric knife; the high-frequency electric knife activates the hardware arbitration module including a logic or circuit, several logic and circuits and switching elements, and the logic or circuit is used to activate the contact of the foot pedal to the electric knife The signal is logically ORed, and one hardware control signal output by the logic or circuit is sent to the master-slave control system for feedback, and the other hardware control signal output by the logic or circuit is logically performed with several software control signals sent by the master-slave control system. And operation, the result of logic and operation is used to control the action switching of the switching element connected to the high-frequency electrosurgical generator. The control method proposed by the invention can also realize a certain degree of fault-tolerant control while detecting a fault and alarming, and can ensure that the electric knife function can still be used in the case of a fault.

Description

technical field [0001] The invention relates to a high-frequency electric knife control system and a control method thereof, and relates to the technical field of medical instruments. Background technique [0002] High-frequency electrotome (also known as high-frequency electrosurgical tool) is an electrosurgical instrument that replaces traditional mechanical scalpels for tissue cutting. Compared with mechanical scalpels, high-frequency electric scalpels have both cutting and coagulation functions, which can greatly improve surgical efficiency and reduce surgical risks. Moreover, the high-frequency electric knife is easier to enter different surgical sites, and can be used in a wide range of operations. Therefore, in the robot-assisted minimally invasive surgery equipment, it is usually equipped with high-frequency electrosurgical tools so that doctors can complete the operation efficiently. Such as figure 1 As shown, the electrosurgical control module of traditional hig...

However, since the high-frequency power output control is completely based on the logical judgment of the software, this method introduces new risks: if the relevant software runs incorrectly, it may lead to wrong high-frequency power output, which may seriously cause the death of the patient
