Abstract

The invention provides a laser ablation system. The laser ablation system comprises a catheter, an ablation device and an OTC imaging device; the ablation device comprises a laser emitter and a first optical waveguide, and the first optical waveguide is arranged in the catheter and used for transmitting a first light beam emitted by the laser emitter to the far end of the catheter from the near end of the catheter; the OCT imaging device comprises an imaging engine, a second optical waveguide and a first optical element set, and the second optical waveguide is arranged in the catheter and used for transmitting a second light beam emitted by the imaging engine from the near end to the far end; and the first optical element set is arranged at the far end, located on the propagation path of the second light beam and used for enabling the focus point of the second light beam to be located in front of the first optical waveguide. The imaging device can provide endoscopic images of blood vessels and can help a doctor to accurately judge the position and the form of a focus so as to determine treatment parameters of laser ablation. After laser ablation, the imaging device can help a doctor to evaluate the treatment effect, so that a next operation plan can be made conveniently.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a laser ablation system. Background technique [0002] In percutaneous coronary intervention, the guiding catheter is usually sent to the coronary artery opening to be dilated, and then a balloon of the corresponding size is sent along the guide wire to the stenotic segment, and dilation is performed with appropriate pressure and time according to the characteristics of the lesion. To achieve the purpose of relieving arterial stenosis. Traditional treatments include angioplasty or stent placement. Plaque ablation is an adjuvant cardiac interventional therapy, including coronary atherectomy and laser ablation. In recent years, excimer laser intracoronary plaque ablation uses catheter design and pulsed ultraviolet cold light source, which improves the effectiveness and safety of the operation. Ultraviolet laser light source can be effectively absorbed by biological tissue, and c...
