Technical field
The present invention relates to a kind of high efficiency water-cooled Microwave Coagulation hemostasis aciculiform antenna, belong to microwave bleeding technical field.
Background technology
Along with the progress of operative treatment science, clinically require more and more higher to the hemostasis during excision of many haemal tissues such as liver, in the art used at present, hemostatic technique has high-frequency electrical, ultrasonic, radio frequency etc.Microwave bleeding utilizes microwave energy to act on blood protein, at once produces heat setting and shutoff effect and stop blooding.Due to speed fast (microsecond), effect is strong and good, temperature low (about 60-80 DEG C) during heat setting, the smog that Non-carbonized causes, and without adhesion, safety does not have antielectrode, becomes in art so have in the future the first trend selected of stopping blooding.
Existing microwave bleeding is all use low-power to export, generally only has 30-40W, the efficiency of antenna is low simultaneously, standing wave is larger, tissue hemostasis very among a small circle can only be used for, hemostasis freezing range only has 5 × 5 millimeter, in operation, can not implement effective coagulation for as many haemal tissues such as liver, spleen, kidneys.
