[0033] To better understand the aforementioned objectives, features, and advantages of this utility model, the disclosed solutions will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments disclosed in the present invention, and not all of them.

[0035] Figures 1-8The panoramic surgical field camera described in this embodiment includes a main body 1, a surgical field camera 2, a wide-angle camera module, and a processing module 4. The main body 1 is hollow, and the processing module 4 is installed inside. The surgical field camera 2 is located at the bottom of the main body 1 and is used to capture the surgical field image. In this embodiment, the surgical field image refers to the surgical field of view, i.e., the area visible during surgery. The wide-angle camera module includes four wide-angle cameras 3 spaced apart around the circumference of the main body 1. These four wide-angle cameras 3 are used to capture environmental images. In this embodiment, the wide-angle cameras 3 are respectively positioned in the front, back, left, and right directions of the main body 1. Two adjacent wide-angle cameras 3 are set at a 90° angle to capture a complete and comprehensive environmental image of the main body 1. The environmental image referred to in this embodiment includes information about the area around the operating table, specifically including but not limited to the operations and communication information of the surgeon and their assistants, and the patient's complete position information while lying on the operating table. The processing module 4 is housed within the main body 1 and is electrically connected to the surgical field camera 2 and the wide-angle camera module, respectively. The processing module 4 can receive and transmit surgical field and environmental images, preprocessing the acquired images before transmitting them to backend devices for subsequent use. In this embodiment, the surgical field camera 2 and the wide-angle camera 3 are conventional components in the field, and the processing module 4 is a commonly used electronic module component in the field.

[0036] Furthermore, the processing module 4 in this embodiment can also stitch together the environmental images captured by each wide-angle camera 3 to form a panoramic environmental image, facilitating the display of the entire surrounding environment. The environmental video images captured by the wide-angle camera 3 are connected to the processing module 4 via a USB port or MIPI interface. In this embodiment, the processing module 4 is specifically a camera video processing board, mainly responsible for video acquisition, preprocessing, H.264 video compression, and 360-degree panoramic video stitching. It supports video push and pull streaming, enables remote display and storage of acquired video, and simultaneously provides commonly used video output interfaces such as HDMI or SDI, supporting local video display and zero-latency video transmission. Considering the requirements of miniaturization, low power consumption, and integrated design, the processing module 4 preferably uses a mature Raspberry Pi 5 or Rockchip embedded hardware platform, on which the program is designed to implement the above functions. Video panoramic stitching and other technologies are existing mature technologies in the field. The specific implementation methods and principles can be referred to existing video panoramic stitching technologies, which will not be described in detail in this embodiment.

[0037] In summary, the panoramic surgical field camera of this embodiment, by setting a surgical field camera 2 at the bottom of the main body 1 and evenly arranging multiple wide-angle cameras 3 at intervals around the outer periphery of the main body 1, and by collecting and transmitting data through the processing module 4 inside the main body 1, can achieve synchronous acquisition and transmission of surgical field images and environmental images. At the same time, the processing module 4 can also stitch together the environmental images captured by each wide-angle camera 3 to form a panoramic environmental image, thereby enriching the field of view and improving the richness and completeness of the surgical process image acquisition. This is beneficial for subsequent research and analysis of operating room procedures using surgical field images and environmental image information.

[0038] Furthermore, such as Figures 1-4 As shown, the panoramic surgical field camera in this embodiment also includes a connecting part 5, which is disposed on the main body 1 to fix the main body 1 to a wall, ceiling, surgical lamp holder, or other device, so that the panoramic surgical field camera can be installed and fixed in a suitable position. The connecting part 5 can be connected by adhesive, bolts, or other methods. Preferably, the connecting part 5 in this embodiment is a boom connector. The main body 1 is connected to a medical boom through the boom connector. The medical boom is a multi-degree-of-freedom robotic arm structure. One end of the medical boom is fixed to the operating table or wall, and the panoramic surgical field camera is installed at the other end. During surgery, the panoramic surgical field camera can be positioned in a suitable position by pushing and pulling the medical boom, so that the panoramic surgical field camera can capture both the entire surgical field and the entire environment. Optionally, the boom connector can be detached and connected to the medical boom by means of threads, plug-in fixing, or other methods. In addition, other types of detachment methods can also be used, including but not limited to the above methods.

[0039] Furthermore, to facilitate the movement and adjustment of the panoramic surgical field camera, this embodiment provides a handle 6 on the main body 1. The handle 6 is disinfected before and after the operation, making it convenient for medical staff to hold and move the panoramic surgical field camera, preventing medical staff from touching the main body 1 and contaminating the surgical field camera 2 and the wide-angle camera 3, which would result in blurred images and unusable footage.

[0040] Optionally, the panoramic surgical field camera in this embodiment also includes a heat dissipation structure 7, such as... Figure 7 As shown, the heat dissipation structure 7 is made of thermally conductive material. In this embodiment, the heat dissipation structure 7 is a block structure made of metal material, which is sandwiched between the processing module 4 and the inner wall of the main body 1. Exemplarily, one side of it is in contact with the main control chip of the processing module 4, and the other side is in contact with the inner wall of the main body 1. When the processing module 4 is running, its main control chip will generate heat. The heat of the main control chip will be transferred to the main body 1 through the heat dissipation structure 7 to achieve the purpose of cooling the main control chip of the processing module 4.

[0041] Optionally, the surgical field camera 2 in this embodiment is rotatably connected to the bottom of the main body 1. For example, the surgical field camera 2 can realize circumferential rotation adjustment and pitch angle adjustment to improve the flexibility of the surgical field camera 2. The specific circumferential rotation adjustment and pitch angle can be referred to the prior art, and will not be described in detail in this embodiment.

[0042] Preferably, the wide-angle camera 3 in this embodiment has a horizontal and vertical viewing angle of not less than 120°, and a resolution of not less than 1080P, which is conducive to shooting a wide range of scenes, can include more elements within a limited distance and produce clear images, thus improving the shooting effect.

[0043] Furthermore, such as Figure 8 As shown, the panoramic surgical field camera in this embodiment also includes a DC / DC power module 8. The external power supply provides power to the surgical field camera 2, the wide-angle camera module and the processing module 4 through the DC / DC power module 8, so as to provide stable power support to the surgical field camera 2, the wide-angle camera module and the processing module 4.

[0044] In addition, this embodiment also provides a panoramic surgical field camera assembly, including a medical boom and the aforementioned panoramic surgical field camera. The medical boom can be a multi-degree-of-freedom robotic arm structure. The medical boom provides mounting points for the panoramic surgical field camera. The panoramic surgical field camera adopts a boom suspension method to better acquire real-time images of the surgical field and the environment.
