SURGICAL TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/130465
Kind Code:
A1
Abstract:
In order to protect blood vessel walls from unintentional surgical treatment, this surgical treatment device (1) is provided with: an energy emission unit (10) for emitting therapeutic energy; a detection laser light irradiation unit (11) for emitting detection laser light; a light detection unit (7) for detecting return light returning from within a biological tissue (X) as a result of irradiation of the biological tissue (X) with the detection laser light by the detection laser light irradiation unit (11); and a blood flow detection unit (8) for detecting blood flow in the detection laser light-irradiated region within the biological tissue (X) using the return light detected by the light detection unit (7). The detection laser light-irradiated region is set to be larger than a region exposed to the therapeutic energy emitted from the energy emission unit (10).
