Abstract

The invention relates to the technical field of medical treatment, in particular to a transbronchial pulmonary artery denervation device which comprises an ultrasonic probe, a bronchoscope, an operation tube, a puncture needle and an ablation catheter. The ultrasonic probe is fixed at one end of the operation tube, the bronchoscope is fixed on the operation tube, and an exchange channel with two open ends is arranged in the operation tube; the puncture needle and the ablation catheter are alternately arranged in the exchange channel in a penetrating manner. The sympathetic nerve of the pulmonary artery adventitia can be directly injured under the guidance of the bronchoscope and the ultrasonic endoscope, meanwhile, the risk of injury of the vascular intima is avoided, the operation difficulty of pulmonary artery denervation is reduced, the operation safety is improved, and a new treatment choice is provided for increasing pulmonary hypertension patients.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a transbronchial pulmonary artery denervation device. Background technique [0002] Currently, pulmonary arterial hypertension (PAH) is a fatal disease characterized by pulmonary vascular remodeling and progressively elevated pulmonary vascular resistance (PVR), which further leads to right heart failure and death. Drugs targeting a variety of different signaling pathways have significantly improved clinical outcomes in some patients with pulmonary arterial hypertension. However, for most patients, the current treatment is only to delay the progression of the disease, and the treatment is expensive, and the right heart failure and even death progress rapidly. [0003] The pulmonary vessels are innervated by 3 different nerve fibers: sympathetic, parasympathetic, and sensory fibers. Sympathetic stimulation of alpha-adrenergic receptors mediates vascular tone. Noradrenergic fib...
