When the lighting source is turned on, the weak light of the fluorescent agent is submerged in the strong light of the lighting source. The fluorescent marked area of ​​the tumor can only be seen when the lighting source is turned off. Therefore, when the lighting source is turned on, this solution cannot display the fluorescent marked area of ​​the tumor. Summary of the invention

[0005] In order to solve the above problems, an object of the present invention is to provide a lighting device for tumor detection and a lighting device for inspection, which can display the fluorescent marking area of ​​the tumor when the lighting light source is turned on.

[0006] In order to achieve the above-mentioned object, the technical solution of the present invention is as follows: a lighting device for tumor detection comprises an endoscope body, and a light-guiding optical fiber is circumferentially arranged on the endoscope body;

[0007] The endoscope body is provided with a first cavity and a second cavity, the first cavity and the second cavity are divided by a partition, a motor is provided in the first cavity, one end of the output shaft of the motor passes through the partition and the second cavity, the output shaft of the motor rotates with the endoscope body, a camera is provided in the second cavity, the camera is installed on one side of the rotating shaft, and the camera is located at one end of the endoscope body;

[0008] A light emitting diode is installed at one end of the endoscope body away from the camera, and the light emitting diode is connected to the light guide optical fiber;

[0009] It also includes a lighting plate installed on the fixed frame, a center lamp is fixedly installed at the center of the lower part of the lighting plate, lighting lamps are arranged circumferentially at the lower part of the lighting plate, and a rotatable auxiliary lamp is provided at the center of the lighting lamp;

[0010] It also includes a processor, which is electrically connected to the motor, the camera, the center light, the lighting light and the auxiliary light.

[0011] The following beneficial effects are achieved by adopting the above scheme: First, the fluorescent substance is injected into the patient's body through a syringe, such as

[0012] The endoscope body is manually inserted into the patient's body. Because a light-guiding optical fiber is arranged circumferentially on the endoscope body, a light-emitting diode is installed at one end of the endoscope body away from the camera. The light-emitting diode is connected to the light-guiding optical fiber. Therefore, the light-emitting diode is located outside the body to avoid the heat source generated when the light-emitting diode is working to harm the human body. Because the light-guiding optical fiber can transmit the light source, the light-guiding optical fiber can map the fluorescent marking area of ​​the tumor in the patient's body.

[0013] The light emitting diode is first started by a processor (the processor includes but is not limited to a common computer, such as a computer with a model of i59600F / GT10304g), and the light emitting diode maps the fluorescent marked area of ​​the tumor in the patient's body through the light-guiding optical fiber. The processor starts the motor, and the output shaft of the motor drives the shaft. The camera rotates with the shaft, so that the camera takes a picture of the fluorescent marked area of ​​the tumor in the patient's body to obtain the fluorescent marked area A of the tumor; then the lighting lamp is started, and the camera takes a picture of the fluorescent marked area of ​​the tumor in the patient's body to obtain the blurred layer B of the tumor (such as Figure 5shown);

[0014] By overlapping A and B, the contour line C of the tumor is obtained when the illumination light source is turned on, and then the center light is turned on by the processor, and the center light will mark inside C (such as Figure 6 The outline is then marked with an auxiliary light so that when the illumination source is turned on, the fluorescent marked area of ​​the tumor can be displayed, making it easier for medical staff to view.

[0015] Furthermore, a support frame is provided between the motor and the endoscope body, and the motor is installed in the first chamber through the support frame.

[0016] Beneficial effect: The support frame facilitates the installation of the motor on the endoscope body.

[0017] Furthermore, a transparent layer is provided between the second chamber and the outside world, the transparent layer is fixedly mounted on the endoscope body, and the second chamber is sealed from the outside world through the transparent layer.

[0018] Beneficial effects: The transparent layer is common quartz glass, which can protect the camera from being damaged by external factors, such as gastric juice in the human body, making it easier for the camera to capture the fluorescently marked area of ​​the tumor in the patient's body.

[0019] Furthermore, a chamfer is provided at one end of the endoscope body away from the light emitting diode, and a side of the chamfer close to the center of the endoscope body is higher than a side of the chamfer away from the center of the endoscope body.

[0020] Beneficial effect: It can reduce the damage to the human body when the endoscope body enters.

[0021] Furthermore, it also includes a human body located between the lighting disk and the endoscope body.

[0022] Beneficial effects: The position of the human body makes it easier for the lighting disc to illuminate the human body and for the endoscope body to illuminate the tumor in the patient's body.

[0023] Furthermore, the light emitted by the LED is not consistent with the light emitted by the lighting lamp. The light emitted by the LED contains fluorescent substances that excite cancer cells in the human body, while the light emitted by the lighting lamp is common white light.

[0024] Beneficial effects: The light emitted by the LED can easily illuminate the fluorescent material of cancer cells in the human body. The fluorescent material emits fluorescence, making it easy to observe the area of ​​cancer cells; the light emitted by the lighting lamp makes it easy for medical staff to perform normal work.

[0025] Furthermore, the light emitted by the center lamp is consistent with the light emitted by the auxiliary lamp, and the light emitted by the center lamp and the light emitted by the auxiliary lamp are ultraviolet rays. The light emitted by the center lamp is located on the human body as a central bright spot, and the light emitted by the auxiliary lamp is located on the human body as an outline bright spot.

[0026] Beneficial effects: Ultraviolet rays have strong penetrating power and can penetrate human skin, making it easier for the camera to capture the bright spots left by the center light and auxiliary light on the human body, facilitating the positioning of the center bright spot, and the contour bright spot to display the outline of the tumor on the human body, making it easier for medical staff to directly observe the location of the tumor on the human body.
