Radio-frequency ablation clamp and application thereof

Abstract

A radio-frequency ablation clamp is provided with a holding portion, an expansion link, a clamp arm and a clamp body, wherein the clamp body is straight or cambered, and 5-7 cm long; and an included angle between the clamp body and the clamp arm is 90-110 degrees. The invention also provides an application of the radio-frequency ablation clamp as a medical instrument in venous ablation of atrial fibrillation treatment. According to the preceding medical device, the radian of the clamp body, the size of the opening of the clamp body, the angle of the clamp body with the clamp arm and the length of the clamp body are improved, so that the problems of the radio-frequency ablation clamp encountered in operation applications are solved and the radio-frequency ablation clamp well meets the requirements in operation. In use of the radio-frequency ablation clamp, only one radio-frequency ablation clamp is needed to complete double-side venous ablation; therefore, the number of the radio-frequency ablation clamp used can be reduced and the operation cost can be also saved for a patient. Besides, the radio-frequency ablation clamp is used with a new atrial fibrillation treatment operation method, so that the operation effect can be improved and operation wounds can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a radiofrequency ablation forceps for radiofrequency ablation and an application thereof. Background technique [0002] Atrial fibrillation (AF) is the most common clinical arrhythmia. According to statistics, there are about 8 million patients with atrial fibrillation in China, and the high-risk group is over 60 years old. Atrial fibrillation can cause many harms to the human body. In atrial fibrillation, the frequency of the atrial beat is extremely fast and irregular. In mild cases, the patient will feel flustered, shortness of breath, and fatigue, which will more or less damage the heart function. If combined with high blood pressure or coronary heart disease, these heart diseases will be aggravated risks of. Atrial fibrillation can also produce serious complications such as atrial thrombus dislodging leading to ischemic stroke, which can cause disability and death....

AI Technical Summary

Problems solved by technology

There are many disadvantages in the original ablation forceps: the length of the forceps body is too short, and the effect of comprehensive ablation cannot be achieved when used; the angle between the forceps body and the forceps arm is too large, which makes the operation inconvenient; For the ablation of the side ring venous ostium, two radiofrequency ablation forceps are required to complete the operation, which increases the burden on the patient; the opening between the two forceps is too small, and the operation is easily interfered by other tissues, which affects the operation process

[0009] Therefore, there is an urgent need for a radiofrequency ablation forceps that can be suitable for a new surgical method for the treatment of atrial fibrillation, but there is no report about this radiofrequency ablation forceps
