Description

Nondestructive auricle tissue grasping forceps

Technical Field

The utility model relates to a medical instrument especially relates to a not damaged auricle tissue nipper.

Background

Atrial fibrillation is the most common cardiac arrhythmia in the clinic, and the most serious complication of atrial fibrillation is a vaso-embolic event. Stroke due to atrial fibrillation is more severe than arteriosclerotic stroke, with higher mortality, longer hospital stay and more serious remaining limb dysfunction. In addition, patients with atrial fibrillation combined with a high ventricular rate also suffer from palpitation and chest distress discomfort, which seriously affect the quality of life of the patients. Long-term atrial fibrillation affects cardiac output and more directly leads to a decrease in cardiac function. Atrial fibrillation is a major public health problem facing today, and its prevalence is increasing, which can cause serious complications and increased mortality. At present, no medicine with a positive curative effect exists, side effects may exist when the anti-arrhythmia medicine is applied for a long time, the recurrence rate of atrial fibrillation is high, the cardiovascular medical catheter ablation has a low success rate of continuous atrial fibrillation, and the minimally invasive maze operation (Cox maze operation) of the cardiovascular surgery is a new hope for radically treating atrial fibrillation at present.

The Cox III type labyrinth cutting suture operation is the best method at present, and the cure rate reaches 99%. However, the incisional suture operation cannot be widely performed all over the world due to the complexity of the operation. Currently, most centers use energy instead of part of the kerf, also known as maze IV surgery. The most important link of the minimally invasive maze operation in cardiovascular surgery is the treatment of the left auricle, and when the left auricle is cut in a tiny incision of 4-5cm, how to grasp and fix the left auricle and avoid the great bleeding caused by the injury of the left auricle is a common embarrassment in the operation process. At present, the adopted method is to use common tweezers or oval forceps to directly clamp the left auricle, however, the auricle tissues are fragile, too strong, and the occurrence of tissue injury and bleeding can occur by carelessness, which affects the next cutting operation.
