Description

Laser ablation device for pulmonary artery high pressure Technical Field The utility model relates to the technical field of medical appliances, in particular to a laser ablation device for pulmonary arterial hypertension. Background Pulmonary arterial hypertension (Pulmonary Arterial Hypertension, PAH) is a serious cardiopulmonary disease characterized by elevated pulmonary arterial pressure, leading to right heart failure and other complications. Current treatments include drug therapies (e.g., endothelin receptor antagonists, phosphodiesterase-5 inhibitors and prostaglandin analogs), oxygen therapy, lung transplantation, and the like. However, these treatment regimens have certain limitations, such as: Drug side effects many drug treatments may cause serious side effects such as hypotension, headache, etc., and patient compliance is poor. The curative effect is limited, the effect of the drug treatment on partial patients is not obvious, and pulmonary arterial hypertension cannot be radically treated. Surgical risk-lung transplantation is an effective but extremely risky procedure and the donor is scarce. Patient individualization-the response of different patients to the same treatment may vary widely, lacking an individualised treatment regimen. Disclosure of utility model The utility model provides a laser ablation device for pulmonary artery high pressure, which aims to solve the problems in the prior art. The utility model aims at realizing the following technical scheme that the laser ablation device for pulmonary artery high pressure comprises: The holding part comprises a holding handle and a catheter sheath which is arranged in the holding handle in a sliding manner, and a physiological saline channel and a fiber channel are arranged in the catheter sheath in a penetrating manner in an axial direction; The ablation portion comprises a normal saline conveying pipe arranged in the normal saline channel and an optical fiber arranged in the optical fiber channel, and one end of the optical fiber is connected with an external laser generator. Further improvement, the optical fiber winding is provided with a circulating water-cooled tube. Further improvement, the catheter sheath is provided with magnetic positioning sensor far away from the end of holding the handle. Further improvement, the catheter sheath is close to one side of holding the handle is provided with fine setting mechanism, fine setting mechanism includes hollow threaded rod, piston tube and piston, the piston tube is close to one side of holding the handle is provided with the rotation base, rotation is provided with the regulating plate in the rotation base, hollow threaded rod slides and sets up in the piston tube and with regulating plate threaded connection, the piston sets up hollow threaded rod is located the one end of piston tube and with the catheter sheath is fixed to be set up. Further improvement, the outer side of the piston tube is provided with scales. Further improvement, the holding handle is provided with anti-skid grooves. Compared with the prior art, the utility model has the following beneficial effects: 1. Minimally invasive, namely, operation is performed through a percutaneous approach, so that the wound is small, and the recovery is quick; 2. The laser can accurately position the lesion area, and reduce the damage to surrounding healthy tissues; 3. the repeatability is that the treatment can be carried out for a plurality of times according to the specific condition of the patient, and the flexibility is high; 4. The treatment effect is that the pulmonary artery pressure is reduced and the life quality of the patient is improved by a denervation fusion mode.
