Abstract

The invention discloses a freezing defibrillator for cardiac surgery, which belongs to the technical field of medical instruments, and aims to solve the problems that tissues are easily burnt, disability is caused and thrombus risks are caused in an electric shock treatment method in the prior art. The freezing defibrillator comprises a freezing airflow guide pipe, the freezing airflow guide pipeis of a cylindrical structure, and an opening in one end of the freezing airflow guide pipe serves as an outflow opening; an inflow adjusting structure is connected with the other end of the freezingairflow guide pipe, the inflow adjusting structure is connected with external freezing air supply equipment through a flow guide pipe, and the amount of freezing air flowing into the freezing airflowguide pipe is adjusted through the inflow adjusting structure; a backflow body is coaxially arranged outside the freezing airflow guide pipe; wherein a freezing cap is detachably connected with the end, close to the flow outlet of the freezing airflow guide pipe, of the backflow body in a sealed mode, the interior of the freezing cap is communicated with the interior of the freezing airflow guidepipe through the flow outlet of the freezing airflow guide pipe, and freezing air in the freezing cap is transmitted to the end, away from the freezing cap, of the backflow body from the end close tothe freezing cap.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a cardiac surgery freeze-defibrillator. Background technique [0002] In recent years, medical technology has developed rapidly, but my country's medical equipment is relatively backward. A large amount of medical equipment needs to be imported every year, which is expensive and has a particularly limited number of uses. Aiming at the problem of atrial fibrillation, surgical ablation of atrial fibrillation is the overall trend now. At present, Atrcure's dual radiofrequency ablation isolation forceps from the United States are popular in China. The dual-radiofrequency ablation isolation forceps adopt electric shock therapy. During the electric shock therapy, if the emergency treatment is too late for anesthesia, the electric defibrillation patient will experience more pain instantly, and there is a risk of thrombosis, which may cause disability and burn tissue...
