Abstract

The invention relates to a laser catheter with adjustable light spots, which comprises a laser emitter, a transmission fibre core and a catheter main body; the laser transmitter is used for generating multiple paths of laser pulses; the transmission fibre core is coupled with the laser emitter and is used for transmitting the laser pulse emitted by the laser emitter so as to output a laser spot; at least two transmission channels which are coaxially arranged are formed in the transmission fibre core; furthermore, a refraction area is formed between every two adjacent transmission channels; the refractive index of the refraction area is smaller than that of each transmission channel; the catheter main body is used for receiving and transmitting the laser spots; the transmission fibre core emits laser spots with different shapes by controlling the opening and closing of different laser pulses; therefore, laser ablation can be carried out on focuses in different shapes; and in addition, in the process, different laser catheters do not need to be replaced, so that the operation is relatively convenient.

Description

technical field [0001] The invention relates to the technical field of laser catheters, in particular to laser catheters with adjustable light spots. Background technique [0002] With the development of laser technology and medical technology, laser ablation technology has gradually become an important means of treating cardiovascular diseases. In laser ablation technology, laser catheters are used to guide laser pulses to lesions in blood vessels for irradiation, thereby achieving the effect of eliminating plaque tissue and dredging blood vessels. [0003] During the actual operation of traditional laser catheters, since the shape of the lesion is irregular, in the process of laser ablation treatment, fiber optic catheters of various sizes are usually used for multiple times of laser ablation to eliminate the lesion. [0004] However, during the operation of the above-mentioned laser catheter, since the optical fiber catheter needs to be replaced many times, the operation...
