Problems solved by technology

In the actual process, some heat will cause thermal damage to the tissue, and the degree of thermal damage will directly affect the effect of the operation
However, at present, doctors make judgments based on experience, which is highly subjective and the results are relatively conservative.

Embodiment Construction

[0034] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0035]The invention provides a method for clinical intelligent percutaneous laser myocardial revascularization, which specifically includes the following steps:

[0036] Step 1, determine the ischemic extent of myocardial tissue, and assess the total blood flow required.

[0037] Before the operation, the left ventricular pressure Δp of the heart was detected by hemodynamics, the blood viscosity η was measured by hemorheology, and the range of myocardial ischemia was detected by positron emission tomography, and the range of total blood flow required for ischemic myocardium was quantitatively evaluated according to clinical experience And set the perfusion volume range of a single laser channel according to clinical experience [V smin ,V smax ], and the aperture range of a single laser channel [d min , d max ].

[0038] In step 2, the ischemic region...

Abstract

The invention discloses a method for carrying out clinical intelligent PMLR (Percutaneous Myocardial Laser Revascularization). By using the method for carrying out the clinical intelligent PMLR, disclosed by the invention, the punching position, the punching number, the punching depth, the pore diameter and the energy during a PMLR process can be integrally optimized, and the method has the effects that under the situation that ischemic myocardium perfusion is met, the myocardium punching number is least, the distribution is uniform, and the heat injury to myocardium around laser punching positions is smallest. The method comprises the following steps of firstly determining an ischemia region of myocardial tissues and a needed total blood flow range; then carrying out grid partition on the ischemic region of the myocardial tissues; then computing the punching position, the punching number, the laser energy, the punching time, the depth and the pore diameter of a laser hole channel aiming at each grid, wherein an optimization method is provided.

Description

technical field [0001] The invention relates to the technical field of medical information, in particular to a clinical intelligent percutaneous laser myocardial revascularization method. Background technique [0002] Coronary heart disease (Coronary heart disease) is one of the most common physical diseases in middle-aged and elderly people, also known as coronary heart disease. In the past 50 years, the incidence of coronary heart disease has continued to increase worldwide, becoming one of the main causes of death, and the incidence of coronary heart disease tends to be younger. 80% of patients with coronary heart disease use traditional drug therapy, percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass grafting (CABG) to relieve their symptoms. But for diffuse coronary lesions, small vessel lesions, distant lesions, late complex cases after multiple PTCA or CABG, and postoperative stent or restenosis cases, the above treatment methods are oft...
