Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A first aspect of the present application provides a laser power density adjusting method, as shown in fig. 1, which is a schematic flow chart of the laser power density adjusting method provided in the present application. The method comprises the following steps:
In embodiments of the present application, when operating with laser light (including, but not limited to, photothermal therapy using laser light), the robotic arm of the laser-operated device operates the laser-emitting optical fiber to be placed in the area to be worked. In order to ensure the accuracy of the laser action range and the safety of the action effect, the optical fiber is fixed at the preset position of the to-be-worked area through the mechanical arm. Here, the optical fiber may be placed in the working area and fixed at the preset position of the working area by manual operation of an operator. In this way, the optical fiber and the region to be acted upon maintain a fixed relative position, and data information describing this fixed relative position can also be derived by measurement.
In the embodiment of the application, the laser beam emitted by the optical fiber of the laser is acted on the plane where the region to be acted is located to form a laser spot. Taking photothermal therapy of tumor as an example, the laser beam emitted by the optical fiber acts on the surface of the tumor to form a laser spot, and the light energy of the laser spot is converted into heat energy to kill tumor cells. The perpendicular distance from the fiber tip to the plane to be acted upon can be measured by using an infrared detection method, but the distance measurement can also be performed by using other methods, which are not limited herein.
And 103, acquiring the value of the scattering angle of the laser beam emitted by the optical fiber when the laser spot of the laser beam emitted by the optical fiber completely covers the region to be acted in the plane to be acted.
In the embodiment of the application, when the laser action area is larger, the laser power required for realizing the same power density is larger. On the premise of ensuring the action effect, the action effect is realized by the laser power which is as small as possible in order to save energy. Therefore, the spot of the laser beam can completely cover the region to be affected. In the operation of photo-thermal tumor treatment, the light spot of the laser beam completely covers the surface of the tumor. The size of the laser beam spot corresponds to the scattering angle of the laser beam, and the value of the scattering angle of the laser beam when the laser spot completely covers the region to be acted is the value of the required scattering angle.
And 104, calculating the power value of the laser according to the vertical distance between the tip of the optical fiber and the plane to be acted, the scattering angle value of the laser beam and a preset target laser power density value.
In the present embodiment, the laser is applied with different materials, and the required laser power density is different. In the photo-thermal tumor treatment surgery, the laser power density required for killing different tumor cells is different. And therefore needs to be adjusted according to the power density that is actually required. In the embodiment of the application, the laser power value required for realizing the laser power density is calculated according to the measured vertical distance between the fiber tip and the plane to be acted on, the value of the scattering angle of the obtained laser beam and the required laser power density value. The required laser power density value can be preset in the processor by an operator or can be input by the operator in the actual operation process.
And 105, adjusting the power of the laser to the calculated power value to obtain the laser power density corresponding to the preset target laser power density value.
In the embodiment of the present application, the power of the laser is adjusted to the calculated power value, so that the required laser power density can be achieved. And the processor automatically adjusts the laser emitted by the optical fiber to the calculated laser power value according to the calculated laser power value. Of course, the power of the laser may be adjusted by manual operation of the operator to adjust the power of the laser to the calculated power value.
According to the laser power density adjusting method provided by the embodiment of the application, the distance between the optical fiber and the plane to be acted on and the value of the scattering angle of the laser beam when the laser beam spot completely covers the area to be acted on are automatically measured. And calculating to obtain the laser power required by realizing the preset laser power density by utilizing the distance between the optical fiber and the plane to be acted, the value of the scattering angle of the laser beam and the preset laser power density value. The target laser power density can be achieved by adjusting the laser power. The method can directly obtain the required laser power density through simple operation, and avoids manual repeated trial and adjustment. The efficiency and the precision of laser power density acquisition have been promoted.
Preferably, the obtaining of the value of the scattering angle of the laser beam emitted by the optical fiber when the laser spot of the laser beam emitted by the optical fiber completely covers the region to be affected in the plane to be affected comprises:
adjusting the scattering angle of the laser beam emitted by the optical fiber, and determining whether a laser spot formed by the laser beam emitted by the optical fiber completely covers a region to be acted in a plane to be acted;
if yes, determining the current scattering angle as the value of the scattering angle of the laser beam emitted by the optical fiber;
if not, returning to the step of adjusting the scattering angle of the laser beam emitted by the optical fiber.
In the embodiment of the application, because the relative position of the optical fiber and the plane to be acted on is fixed, the light spot formed by the laser beam emitted by the optical fiber and irradiated on the action plane can be adjusted by adjusting the scattering angle of the laser beam emitted by the optical fiber. In general, the scattering angle of the laser beam is adjusted from small to large, and the laser spot formed on the plane to be acted on by the laser beam is gradually increased. And judging in real time in the process of adjusting the scattering angle of the laser beam emitted by the optical fiber, stopping adjusting when the laser spot completely covers the region to be acted, and determining the scattering angle at the moment as the required scattering angle of the laser beam emitted by the optical fiber. If the laser spot does not completely cover the area to be affected, the adjustment is continued.
It can be understood that, here, whether the laser spot completely covers the region to be acted may be determined manually by an operator or by equipment. Such as using image comparison function determination, etc.
The method for acquiring the scattering angle value provided by the embodiment of the application can acquire the scattering angle value of the laser beam when the laser spot completely covers the region to be acted, and avoids the condition of poor action effect or resource waste caused by inaccurate acquisition of the scattering angle value.

in the formula, P is a power value of the laser, D is a preset target laser power density value, h is a vertical distance from the tip of the optical fiber to a plane to be acted on, and θ is a scattering angle value of a laser beam emitted by the optical fiber.
In the embodiment of the present application, the laser power density is a ratio of the laser power to the laser spot area. That is, D is P/S, where D is the laser power density value, P is the laser power value, and S is the laser spot area. Since the laser spot is circular, S ═ tr2And r is the radius of the laser spot circle. Fig. 3 is a schematic view of a laser in the embodiment of the present application. In the figure, r is the radius of a laser spot circle, h is the vertical distance from the tip of the optical fiber to a plane to be acted on, and theta is the value of the scattering angle of the laser beam emitted by the optical fiber. Then there is r — htan θ. Then P is not equal to D pi r2I.e. P ═ D ═ pi ═ h2*tan2θ。
