[0002] Surgical lights, which are one of the medical lighting devices, are designed to illuminate a patient's affected area on an operating table or treatment table with uniform brightness without creating shadows. In order to perform surgery smoothly depending on the location of the affected area, the depth or area of ​​the incision, the position, area, and angle of the lighting of the surgical light must be easily adjustable. In other words, it was necessary to adjust the lighting position to illuminate the area where surgery is being performed according to the surgical situation and the three-dimensional shape of the incision, to adjust the angle of light from the light source toward the light-collecting plane (surgical area or incision area), and to adjust the area of ​​light illuminated to suit the size of the surgical area.

[0025] Now, the configuration and operation of a medical lighting device that provides patient-customized lighting according to a preferred embodiment of the present invention will be described.

[0026] <Composition of a medical lighting device providing patient-customized lighting>

[0027] FIG. 1 is a configuration diagram of a medical lighting device providing patient-customized lighting according to a preferred embodiment of the present invention. Referring to FIG. 1, the medical lighting device providing patient-customized lighting is composed of a wall controller (100), a lighting device (200), and an RFID card (300).

[0028] The above wall controller (100) is responsible for the interface between the user and the lighting device (200) and consists of an RFID reader (102), a user input unit (104), and a display unit (106).

[0029] When the RFID card (300) approaches within a valid range, the RFID reader (102) reads the RFID card information stored in the RFID card (300) and provides it to the control device (202) of the lighting device (200), or writes the RFID card information provided by the control device (202) to the RFID card (300).

[0030] The above user input unit (104) and the above display unit (106) employ a touch screen, etc., to receive various input information from the user and provide it to the control device (202) of the lighting device (200), or receive various display information from the control device (202) and display it to guide the user.

[0031] The above lighting device (200) is composed of a control device (202), a memory unit (204), a lighting unit (208), and an imaging unit (210).

[0032] The above control device (202) controls each part of the wall controller (100) and the lighting device (200) to provide patient-customized lighting according to a preferred embodiment of the present invention.

[0033] The memory unit (204) stores various information including a processing program of the control device (202).

[0034] The sensor devices (206) are composed of sensors for performing the function of the lighting device (200), and such sensors may include one or more of the following: an illuminance sensor for measuring the brightness of the light reaching the surgical site, a color temperature sensor for monitoring the color temperature of light to provide light close to natural light, an infrared sensor for non-contact control and detection, a temperature sensor for monitoring the heat generated by the lighting device, a motion sensor for detecting the movement of a user, a gyroscope and accelerometer for detecting the angle and position of the lighting head, and a proximity sensor for measuring the distance between the lighting device and the surgical site.

[0035] The lighting unit (208) generates and emits medical lighting of surface light by combining multiple LED arrays (LA) in which multiple LED modules are arranged as shown in FIG. 2, under the control of the control device (202).

[0036] The above imaging unit (210) images the affected area of ​​the patient within the illumination emission area of ​​the above illumination unit (208) and provides the corresponding imaging information to the control device (202).

[0037] The operation of the control device (202) of the lighting device (200) described above is explained further.

[0038] The above control device (202) extracts lighting control information included in the RFID card information when the RFID reader (102) reads and provides RFID card information stored in the RFID card (300) that is within effective range, and drives the lighting unit (208) by controlling the lighting output state of the lighting unit (208) according to the lighting control information, and the lighting output state is configured to include one or more of the PWM adjustment state, intensity adjustment state, sensor data, and driving mode of the lighting driving signal provided to the lighting unit (208).

[0039] Additionally, when the RFID card (300) is activated through the RFID reader (102) while the lighting unit (208) is in operation, the control device (202) includes lighting control information corresponding to the current lighting output state of the lighting unit (208) in the RFID card information and lights the RFID card (300), and at the same time stops the operation of the lighting unit (208).

[0040] In addition, the control device (202) extracts imaging control information included in the RFID card information and controls the imaging state of the imaging unit (210) according to the imaging control information to drive the imaging unit (210), and the imaging state is configured to include one or more of a zoom state, a focus state, an aperture value, and an imaging direction.

[0041] In addition, the control device (202) receives the image information captured by the imaging unit (210) after controlling the imaging state, and stores it in the memory unit (204) in correspondence with the patient identification information included in the RFID card information. In this way, the present invention enables the imaging information captured during surgery or procedure to be classified and stored by patient using only RFID tagging.

[0042] In addition, when the RFID card (300) is activated through the RFID reader (102) while the lighting unit (208) is in operation, the control device (202) includes imaging control information corresponding to the imaging state of the current imaging unit (210) in the RFID card information and writes to the RFID card (300), and stops the operation of the imaging unit (300).

[0043] The software configuration provided in the above-described control device (202) is as illustrated in FIG. 3. Referring to FIG. 3, the control device (202) is provided with a lighting control unit (250) and an imaging control unit (260).

[0044] The lighting control unit (250) comprises a PWM control unit (252) that adjusts the PWM of the lighting driving signal provided to the lighting unit (208), an intensity adjustment unit (254) that adjusts the intensity of the lighting, a sensing processing unit (256) that processes sensing data from the sensors of the sensor devices (206), and a mode processing unit (258) that controls the driving mode of the lighting unit (208). Here, the driving modes of the lighting unit (208) include a general lighting mode used for surgical preparation and general activities, a surgical spot mode that concentrates strong light on a specific area to allow the surgical site to be recognized more clearly, an endoscopy mode which is a low-brightness lighting mode to support laparoscopic or endoscopic surgery, a color adjustment mode that allows the color of the tissue to be accurately distinguished, and a shadowless mode that minimizes shadows caused by the movement of medical staff or equipment.

[0046] A procedure for a patient-customized lighting provision method applicable to a medical lighting device providing patient-customized lighting according to a preferred embodiment of the present invention described above is explained.

[0047] <Procedure for Providing Patient-Customized Lighting>

[0048] FIG. 3 is a flowchart of a method for providing patient-customized lighting according to a preferred embodiment of the present invention. Referring to FIG. 3, a control device (202) of a medical lighting device providing patient-customized lighting checks whether the lighting unit (208) is in a lighting driving state that emits light (step 400).

[0049] When the above lighting operation state is not active, the control device (202) checks whether the RFID card (300) approaches within the effective range of the RFID reader (102), i.e., whether it is tagged (step 404). When the RFID card (300) approaches while the above lighting operation state is not active, the RFID card information stored in the RFID card (300) is read through the RFID reader (102) (step 404).

[0050] When the RFID reader (102) reads RFID card information, the control device (202) extracts patient information, lighting control information, and imaging control information from the RFID card information (step 406). Here, the patient information is composed of information such as patient identification information, name information, age, gender, and medical history, the lighting control information is composed of one or more of the PWM adjustment state, intensity adjustment state, and driving mode of the lighting driving signal, and the imaging control information is composed of one or more of the zoom state, focus state, aperture value, and imaging direction.

[0051] The above control device (202) controls the lighting unit (208) so that the lighting unit (208) is driven according to the lighting control information extracted from the RFID card information (step 408), thereby enabling the lighting to be turned on without manual operation by the user, and also enables the lighting to be output in a controlled lighting output state according to the lighting control information included in the RFID card information.

[0052] In particular, the lighting control information is configured to correspond to the lighting output state used during the patient's surgery or treatment and is stored in an RFID card (300). By simply tagging the RFID card (300) to the RFID reader (102), the user turns on the lighting and outputs the lighting in the same state as used during the previous surgery or treatment, thereby providing customized lighting for the patient and minimizing manual operation of the lighting device (200), thereby preventing the risk of contamination caused by manual operation.

[0053] In addition, the control device (202) controls the imaging unit (210) so that the imaging unit (210) is driven according to the imaging control information extracted from the RFID card information (step 410), thereby enabling imaging to be initiated without manual operation of the imaging unit (210) by the user, and also enables imaging to be performed in an imaging state according to the imaging control information included in the RFID card information. In addition, after controlling the imaging state, the control device (202) receives the imaging information captured by the imaging unit (210) and stores it in the memory unit (204) in correspondence with the patient identification information included in the RFID card information.

[0054] In addition, the control device (202) outputs patient information extracted from the RFID card information through the wall controller (100) via the display unit (106) of the wall controller (100) to guide the medical staff.

[0055] In addition, the control device (202) checks whether the RFID card (300) approaches within the effective range of the RFID reader (102) even in the lighting operation state, that is, whether it is tagged (step 414). When the RFID card (300) approaches within the effective range of the RFID reader (102) in the lighting operation state, the control device (202) configures information regarding the current lighting control state as lighting control state information and information regarding the current imaging control state as imaging control information, combines this with patient information to generate RFID card information indicating the lighting output state and imaging state used during surgery or treatment for the patient, and writes it to the RFID card (300) (step 416).

[0056] Afterwards, the control device (202) initializes the control state of the lighting unit (208) and the imaging unit (210) and turns them off to terminate operation (step 418).

[0057] The above control device (202) stores information about the control state of the lighting unit (208) and the imaging unit (210) in real time whenever the control state of the lighting unit (208) and the imaging unit (210) changes, so that when the RFID card (300) is tagged, the RFID card information can be quickly generated and written.

[0058] In the preferred embodiment of the present invention described above, when an RFID card is tagged, lighting corresponding to the lighting output state and imaging state used during the previous surgery or treatment of the patient recorded on the RFID card is output, and imaging is performed. However, if the lighting device is equipped with a function to vary the angle or position of the lighting using a robot arm, information regarding the robot arm state is configured as robot arm control information and added to the RFID card information and stored. When the RFID card is tagged, the robot arm is also controlled according to the robot arm control information to drive the robot arm according to the state of the robot arm used during the previous surgery or treatment, and this is obvious to those skilled in the art by the present invention.

[0059] The embodiments of the present invention described above are disclosed for illustrative purposes only, and those skilled in the art will be able to make various modifications, changes, and additions within the spirit and scope of the present invention, and such modifications, changes, and additions should be considered to fall within the scope of the claims.
