Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to an ablation system.
Background
Ablation techniques such as radiofrequency ablation have been widely used in interventional procedures including cardiac arrhythmias, refractory hypertension, tumors, etc. In arrhythmia treatment, an ablation catheter enters the heart through a blood vessel, an abnormal electric signal path or a point emitting an abnormal electric signal is found based on mapping of an electric signal in the heart, ablation is carried out in the heart, transmission of the abnormal electric signal is prevented, a patient is enabled to recover sinus rhythm, and the treatment effect is achieved.
In refractory hypertension treatment, a monopolar renal artery radiofrequency ablation catheter has been presented to perform renal artery radiofrequency ablation procedures. The renal artery radio frequency ablation operation is an interventional technique for removing nerves by sending an electrode catheter to a specific position in a renal artery through a blood vessel and releasing radio frequency energy to cause local coagulative necrosis of sympathetic nerves of the renal artery. The damage range of the radio frequency energy is small, and the damage to the body can not be caused, so the radio frequency ablation operation of the renal artery becomes an effective method for removing the sympathetic nerve of the renal artery. At present, it is considered by the surgeon that damage to the sympathetic nerve in the aorta can also play a role in treating hypertension.
The radio frequency ablation system for the renal artery radio frequency ablation operation generally comprises a radio frequency ablation instrument for generating radio frequency energy and a radio frequency ablation catheter for transmitting the radio frequency energy into the renal artery, wherein an electrode is carried on the radio frequency ablation catheter, the radio frequency ablation catheter enters a human body through a femoral artery and reaches the inside of the renal artery, the radio frequency ablation instrument is started to generate the radio frequency energy, and the radio frequency energy is transmitted to a part needing ablation through the electrode to work. For ease of operation, rf ablators typically include an rf ablator faceplate and foot pedals that an operator controls the output and interruption of rf energy by depressing and releasing.
However, the radio frequency ablation instrument in the radio frequency ablation system only provides radio frequency energy to ablate an ablated part, and the ablated part in the radio frequency ablation operation is judged and operated only by the experience of an operator, and for the operator with insufficient experience, the ablation target point may not be accurately judged, so that excessive ablation or a satisfactory operation effect result cannot be achieved, and a great risk is generated for the patient.
