Argon flow control method and system

Abstract

The invention provides an argon flow control method and system. The control method includes the steps that S1, argon is introduced into an argon jet pipe, and residual gas in the argon jet pipe is completely discharged; S2, argon is introduced into the argon jet pipe continuously, high-frequency voltage is output for ignition, and argon is ionized; S3, after ignition is finished, an argon pulse stream adjustable in flow value is introduced into the argon jet pipe, and argon ionization is maintained in the spark discharge state or between the spark discharge state and the arc discharge state. By means of the method, argon ionization is maintained in the spark discharge state or between the spark discharge state and the arc discharge state, the burning area is large, biological tissue needing inactivating can be removed at a time, and a good and fast blood coagulation effect is achieved for large-area diffuse hemorrhage.

Description

technical field [0001] The invention relates to the field of medical electrosurgery, in particular to an argon gas flow control method and control system. Background technique [0002] The Argon Flow Controller is an electrosurgical instrument used with an electrosurgical energy platform for tissue cutting or hemostasis. The argon gas flow controller can be used alone as a device, or it can be combined with the electrosurgical energy platform in a device and used as an all-in-one machine. During surgery, through the combined use of the argon gas flow controller and the electrosurgical energy platform, the temperature of the tissue can be reduced during cutting, carbonization can be reduced, and large-area blood can be coagulated without contact during blood coagulation, and the coagulation time can be shortened, especially when used under endoscopy. , this function can greatly simplify the doctor's operation and improve the efficiency when dealing with large area bleeding, ...

AI Technical Summary

Problems solved by technology

[0010] 1. The argon gas output during ionization is a constant argon gas flow rate set by the user. When the flow rate set by the user is small, it is not easy to ignite. When the flow rate is set high, it is easy to cause carbonization and eschar of biological tissues.

[0011] 2. After ignition, it quickly enters the arc discharge state, forming a slender arc to inactivate and coagulate biological tissues. The burning area is small, and it is often impossible to complete the inactivation and removal of diseased tissues at one time;

[0012] 3. The depth of arc discharge thermal injury is relatively large, and there is a certain risk of perforation when performing operations on the intestinal wall
