Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to a composite balloon catheter system with a real-time monitoring function.
Background
With the aggravation of population aging and the influence of factors such as environment, diet, life habit and the like, the incidence of vascular calcification and/or valve calcification is increasing year by year. When calcification of a blood vessel is required to be opened or a thin film formed by slight calcification is required to be repaired, it is common practice to use an inflatable balloon for pre-inflation. This typically requires significant pressure, and the inflatable balloon is gradually inflated under internal pressure until the pressure within the balloon ruptures or bursts the calcified lesions, which may also cause damage to the blood vessel. In order to solve the problems of vascular injury, such as interlayer, vascular stress fracture, hole breakage and the like, caused by the pre-expansion of a simple high-pressure balloon, a device with a function of generating shock waves starts to appear, so that atherosclerosis or calcified lesions of stenosed diseased blood vessels are reshaped and then communicated, the electrodes form cavitation bubbles to generate shock waves by emitting ultrasound into the balloon filled with a fluid medium, and the shock waves impact calcified areas to crush calcified lesions.
In the prior art, the calcified position is usually detected firstly and then the balloon is put into the position to break the calcified position, and as the balloon and the detection element are not integrated together, the detection can not be carried out while the shock and impact are carried out, and whether the balloon is opened or not can be judged only by moving the balloon, or the balloon is taken out for detection again, so that the operation process is complicated.
A balloon catheter with a sensing fiber is disclosed in patent number CN201780043851, which, although giving a suggestion of a balloon catheter in combination with a sensing fiber, is still a pre-detection solution and not a solution where detection is synchronized with shredding calcified sites.
In the prior art, the calcified part is still detected first, then the detection device is taken out, the calcified lesion is broken by using the inflatable air bag, the action time of the shock wave can be judged through the bending degree or thickness of the calcified part, but as the action time of the shock wave is obtained through calculation, certain errors still exist in the actual operation process, if the action time of the shock wave is too long, the shock wave can act on the surface of normal skin to cause discomfort to a patient, if the action time of the shock wave is too short, residual calcified lesion exists, and the errors are often smaller, so that the basic operation requirement can be met in general, along with the development of science and technology and the increase of the requirements of people on life quality, the medical field also needs to be continuously improved, and people more pursue the accuracy and comfort of the operation.
In addition, the balloon catheter in the prior art is only provided with the vibration wave element on the circumferential surface of the catheter, the crushing effect on annular calcification is good, the crushing effect on axial calcification is poor, when the calcification part is reached initially, the calcification part in front of the axial calcification part needs to be crushed firstly, because the vibration wave element on the circumferential surface is only provided, the accurate positioning crushing cannot be realized, the time consumption in the elimination process is long, and normal skin tissues can be damaged.
Therefore, how to design a balloon catheter system capable of precisely smashing calcified parts and realizing the integrated primary monitoring-shock wave treatment-real-time retesting process of calcified blood vessels is a technical problem to be solved at present.
