[0002] With the continuous development of modern medical technology, more and more information equipment has entered the surgical operating room, including surgical video recording equipment. This type of equipment is mainly used to shoot the doctor's surgical process and record surgical operations. And due to the continuous development of the current 5G communication technology, the transmission speed of video information has been greatly improved, and it is no longer limited by the distance in space. Surgical videos can also be further used for remote consultations to solve the problem of unbalanced surgical resources between regions. However, in order to make the surgical video realize the above functions, it is necessary to record high-definition, unobstructed, and appropriately shot surgical videos, but the existing surgical video recording equipment is difficult to meet the above requirements.

[0003] Most of the surgical video recording equipment currently in use requires manual adjustment of the shooting angle. Due to the sterility requirements of the operating room, the surgeon is often unable to adjust it by himself and needs the assistance of the nurses around him. This method of assisting others in shooting often results in the recorded surgical video not being able to highlight the key points. In addition, some surgical video recording equipment is difficult to operate and requires a certain degree of prior learning, which is not convenient for medical staff to use and operate.

DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] The present invention aims at the problems of the existing surgical video recording equipment and provides a handheld posture indicator that meets the hospital's disinfection requirements. After the posture indicator is disinfected, the doctor can move the handheld posture indicator to the sterile area of ​​the operating room and control it to point to the desired shooting target at the desired shooting angle; then press the designated button, and the posture indicator will send instructions to the surgical video recording equipment; finally, the surgical video recording equipment recognizes the posture of the indicator and controls the camera to shoot the desired target. This handheld small posture indicator solution solves the problem that the shooting angle of the existing surgical video recording equipment is difficult to adjust and the surgeon cannot directly adjust it.

[0023] like Figure 1-3 As shown, the overall structure of the posture indicator of the embodiment of the present invention mainly includes a QR code housing 1 and an indicator handle; the indicator handle is composed of three parts: an indicator handle bracket 10, an indicator handle housing 3, and an indicator handle battery housing 5. An indicator wireless communication module 2 and an indicator main control board 12 are arranged inside the QR code housing 1. A laser light 4, a battery, a laser light control switch, and an indicator main power control switch are installed on the indicator handle.

[0024] In the position indicator, the main component related to visual processing is the QR code shell 1. The basic shape of the QR code shell 1 is a hollow prism, and there are a total of 5 faces on the shell with QR codes drawn. The QR code used is the AprilTag tag. By collecting and processing the image of this QR code tag through the surgical video recording equipment, the position of the indicator in three-dimensional space can be calculated. Figure 1-4 As shown, a QR code is attached to the upper surface and four sides of the QR code shell 1 of the embodiment of the present invention. The QR code shell 1 of the embodiment of the present invention is processed on the basis of a regular prism structure, and the excess area of ​​the side trapezoid is processed on each edge of the side, so that the side trapezoid becomes a square for attaching a square QR code, and also reduces the volume of the prism. The prism bevel design of the QR code shell 1 of the present invention takes into account the hand-holding method of medical staff and the fact that the surgical video acquisition equipment is often located above the surgical space, so that the QR code has a specific inclination angle, which is convenient for the surgical video recording equipment to record the most QR codes, so as to improve the recognition accuracy; at the same time, in order to ensure that the indicator is small in size, the degree of inclination should not be too large, and 10° is more appropriate. The QR code pattern of the present invention is treated with a special matte spray paint, and there will be no reflection problem under the strong light of the operating room.

[0025] like Figure 1-2As shown, the upper end of the indicator handle bracket 10 is a platform with a central through hole, which will be fixedly connected to the bottom of the QR code housing 1. The indicator wireless communication module 2 and the indicator main control board 12 are located above the platform and installed on the top surface inside the QR code housing 1. The power connection lines of the indicator wireless communication module 2 and the indicator main control board 12 are connected to the power supply of the handle bracket through the central through hole. After the upper end of the handle bracket 10 is fixedly connected to the bottom of the QR code housing 1, the contact surface is sealed to isolate the hardware circuit inside the QR code housing 1 from the outside.

[0026] The posture indicator is controlled by two buttons, namely the laser light control button 7 and the power control switch 8. The laser light control button 7 is used to control the on and off of the laser light 4. The laser light 4 located at the bottom of the indicator handle can emit a green laser dot, which is convenient for the user to determine whether he is pointing to the desired shooting position correctly. The power control switch 8 is used to control the power on and off of the entire posture indicator. Two buttons 7, 8 and openings for the laser light 4 are set at corresponding positions of the indicator handle housing 3 for assembly. After assembly, the contact surface between the housing 3 and the indicator handle bracket 10 is sealed with sealant.

[0027] The hardware circuit part of the indicator is mainly composed of an indicator wireless communication module 2, an indicator main control board 12, an indicator button control board 9, a battery shrapnel 11 and an indicator battery 6. The indicator main control board 12 is used to process the information sent and received by the posture indicator, and a buzzer is also integrated therein, which will emit a specified prompt tone for the control status of the posture indicator. The indicator wireless communication module 2 is used for communication between the posture indicator and the surgical video recording device. The indicator button control board 9 is connected to the indicator main control board 12, the laser light control button 7 and the power control switch 8. The indicator button control board 9 is used to identify the button information of the posture indicator and send it to the indicator main control board 12 for processing. The battery shrapnel 11 is arranged in the battery compartment to facilitate the user to disassemble and install the battery. The indicator battery 6 in the embodiment of the present invention uses a 14500 lithium battery with a supply voltage of 3.7V.

[0028] The indicator button control board 9 identifies the button information of the posture indicator and sends it to the indicator main control board 12. The button information includes which button is pressed or released, and the pressing time. In the embodiment of the present invention, the button information for starting and shutting down the posture indicator is set in advance in the indicator main control board 12, and the button information for turning on the laser light 4 and the button information for positioning the laser light 4 are set, as well as the processing operation of the corresponding button information. The indicator button control board 9 sends the identified button information to the indicator main control board 12 for processing. When the indicator main control board 12 obtains the on button information of the power control switch 8, it starts the posture indicator and prompts through the buzzer. When the off button information of the power control switch 8 is obtained, the posture indicator is turned off. When the indicator main control board 12 obtains the button information for turning on the laser light 4, it controls the laser light 4 to light up. When the button information for positioning the laser light 4 is obtained, the identification instruction is sent to the surgical video recording device, and the laser light 4 is controlled to turn off.

[0029] The recognition instruction of the posture indicator is used to notify the surgical video recording device that the indicator is now correctly pointing to the shooting target, and the QR code pattern on the indicator can be recognized and processed. The recognition instruction of the posture indicator is continuously sent to the surgical video recording device from the moment it is confirmed to be sent, and the posture indicator stops sending the recognition instruction after receiving the message from the surgical video recording device that the recognition instruction has been successfully received. The purpose of such communication is to ensure that the recognition instruction of the posture indicator can be transmitted to the surgical video recording device.

[0030] In an embodiment of the present invention, in the off state, long press the power control switch to start the device; in the on state, long press the power control switch to shut down the device; in the laser light off state, short press the laser light control button to light up the laser light; in the laser light on state, short press the laser light control button to turn off the laser light; in the laser light on state, long press the laser light control button, and the indicator sends an identification instruction to the surgical video recording device.

[0031] The overall structure of the posture indicator is connected and fixed by bolts, and sealing rings are installed on the contact surfaces of each component for isolation. Sealing glue is also applied on the contact surfaces of the indicator handle bracket 10 and the indicator handle housing 3 to isolate the external environment so that it will not affect the internal circuit hardware during disinfection.

[0032] like Figure 4 , which is a rendering of a posture indicator obtained according to an embodiment of the present invention.

[0033] A step of using the posture indicator of an embodiment of the present invention is as follows:

[0034] (1) The operator presses and holds the power control switch 8 of the posture indicator for three seconds until the posture indicator emits a "beep, beep" prompt sound and then releases it. At this time, the posture indicator has been started normally. The operation of shutting down the posture indicator is the same.

[0035] (2) The operator short presses the laser light control button 7 of the posture indicator, and the laser light 4 at the bottom of the posture indicator lights up and emits a green laser dot.

[0036] (3) The operator holds the posture indicator and points it at the desired shooting target at the desired shooting angle, so that the green laser dot falls on the desired shooting position. At this time, it means that the posture indicator is correctly pointing to the shooting target.

[0037] (4) After confirming that the posture indicator is correctly pointing to the shooting target, press and hold the laser light control button 7 until the posture indicator emits a "beep" prompt sound and then release it. At this time, the laser light 4 at the bottom of the posture indicator will also automatically turn off, and the recognition command of the posture indicator has been sent to the surgical video recording device.

[0038] The surgical video recording device obtains the desired shooting posture by identifying the QR code on the posture indicator, controls the camera movement and shoots the desired target.

[0039] Except for the technical features described in the specification, all of them are known technologies to those skilled in the art. The present invention omits the description of known components and known technologies to avoid redundancy and unnecessary limitation of the present invention. The implementation methods described in the above embodiments do not represent all implementation methods consistent with the present application.
