AI Technical Summary

Technical Problem

Existing electric snare devices are prone to thermal damage, smoke obscuring vision, and electrical safety hazards under high-frequency current, affecting surgical outcomes and safety.

Method used

The device employs a low-temperature plasma bipolar electric snare. Through its bipolar electrode structure and annular dripping chamber design, it utilizes physiological saline to form a low-temperature plasma layer for tissue cutting and coagulation. The dripping system washes away the fumes, preventing thermal damage and the passage of current through the human body.

Benefits of technology

It reduces the extent of tissue thermal damage, improves the clarity of the surgical field and electrical safety, reduces the risk of perforation, and ensures cutting efficiency and operational stability.

Abstract

The application discloses a low-temperature plasma bipolar loop snare with water dripping, which is characterized in that a ring-shaped water dripping cavity is arranged in the loop snare, and a water outlet is arranged at the head end of the loop snare, so that physiological saline can be continuously delivered to the working area of the electrode, and a low-temperature plasma layer is formed under the joint action of the electrode and the physiological saline, thereby realizing tissue cutting and blood coagulation and effectively reducing the range of tissue thermal injury; meanwhile, the water dripping system can cool the electrode and the target tissue, and flush the smoke and carbide generated in the cutting process, so that the endoscopic vision is kept clear; in addition, the application adopts a bipolar electrode structure, so that a current loop is formed between the electrodes, and a loop through the human body is not needed, thereby improving the electrical safety during the operation; through the above structural design, the application can ensure the tissue cutting efficiency, reduce the risk of perforation and improve the operation stability, and has good clinical application value.
