Problems solved by technology

But this method has many disadvantages: First, the safety of photothermal enhanced substances is a difficult problem
Most of the photothermal enhancement substances reported so far have toxic and side effects, especially at higher doses, which bring risks and burdens to the metabolic organs of the body, such as liver, kidney, etc.
Secondly, it is difficult for photothermal enhancement substances to achieve specific uptake in the target area
And any uptake outside the target area brings the risk of damage to healthy tissues and organs for photothermal therapy

Abstract

The present invention discloses an imaging-based light heating device. The imaging-based light heating device comprises an optical imaging component for imaging an object irradiation area, a projection component for light irradiating the irradiation area, a heating light source and a control device; the optical imaging component is electrically connected to the control device by an imaging deviceand the projection component is electrically connected to the control device; light of the object irradiation area is imaged in the imaging device via the optical imaging component to obtain an imageof a target irradiation area; the image of the object irradiation area is transmitted to the control device; and the control device selects a portion of the image to be heated according to the image and controls the projection component according to the selected partial image, so that the projection component enable heating light of the heating source to return along the original path of an imaging optical path of the optical imaging component to heat the corresponding object area of the selected partial image. The above device can be applied to the fields of medical treatment, physiotherapy and cosmetology, and is safe and controllable in use and also low in cost.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to an imaging-based light heating device. Background technique [0002] The photothermal effect has a wide range of applications in the fields of medicine, rehabilitation, and cosmetology. It has a large number of applications in the fields of tumor hyperthermia, laser irradiation coagulation, physical therapy to promote tissue regeneration, wrinkle removal and beauty, and meridian acupoint irradiation therapy. In these applications, the controllability of lighting has always been the biggest problem. [0003] Hyperthermia is a method of using excessive heat for the treatment of diseases such as tumors. High temperatures can cause cell death. When the temperature rises above 42°C, the heat energy begins to damage human cells. The degree of thermal energy damage to cells depends on the temperature and duration of action, and this phenomenon is especially evident for ...
