[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations. Example

[0016] Please refer to Figure 1 An embodiment of the present invention provides a multi-angle adjustment imaging device for a temporomandibular arthroscopy, which relates to the field of medical device technology. The device includes: a controller 1 and a working rod 2, wherein the working rod 2 includes an outer tube 3 and an inner-driven telescopic rod 4 coaxially connected to the outer tube 3, one end of the outer tube 3 is open and the other end is connected to the controller 1, one end of the inner-driven telescopic rod 4 is connected to the controller 1, and the inner-driven telescopic rod 4 is rotatably connected to one end away from the controller 1 with an imaging component.

[0017] It is worth noting that the existing multi-angle adjustment device still has certain deficiencies in angle adjustment and test width when applied to temporomandibular arthroscopy. A multi-angle adjustment imaging device for temporomandibular arthroscopy is provided, which includes a controller 1, a working rod 2, an outer cylinder 3, an inner-drive telescopic rod 4, and an imaging component. When not in use, the imaging component is located inside the outer cylinder 3. When in use, the controller 1 is held to send the working rod 2 to the position where the patient needs to be examined, and then the inner-drive telescopic rod 4 is controlled to extend and extend out of the outer cylinder 3, thereby sending the imaging component out of the outer cylinder 3, and then the imaging component is controlled to rotate around the inner-drive telescopic rod 4 to a specified angle, thereby realizing the acquisition of images at multiple angles and multiple field of view ranges, solving the problem in the prior art that certain lesions may be ignored due to fixed angles.

[0018] Furthermore, a rotating ball 5 is rotatably connected between the inner drive telescopic rod 4 and the imaging assembly. The arrangement of the rotating ball 5 enables the imaging assembly to rotate around the end of the inner drive telescopic rod 4.

[0019] Furthermore, a semi-spherical cover 6 is movably connected to the outside of the rotating ball 5, and the semi-spherical cover 6 is connected to the imaging component. The rotating ball 5 is tightly fitted with the inner wall of the semi-spherical cover 6, so that the semi-spherical cover 6 can rotate around the rotating ball 5 at multiple angles. That is, the operator can drive the semi-spherical cover 6 to rotate around the rotating ball 5 through the controller 1 to adjust the specific angle of the imaging component, which can effectively ensure the angle adjustment flexibility of the imaging component.

[0020] Furthermore, the imaging assembly at least includes a fixing base 7 and a plurality of image acquisition heads 8 connected to the fixing base 7, and the fixing base 7 is connected to the hemispherical cover 6. The plurality of image acquisition heads 8 respectively acquire image data according to preset directions, and transmit the data to the controller 1 for processing and analysis. The orientations of the plurality of image acquisition heads 8 are different, and the optical axes of the plurality of image acquisition heads 8 have specific angles with each other. For example, the angle between the optical axis of one image acquisition head 8 and the optical axis of another image acquisition head 8 ranges from 30° to 90°, so as to ensure that each image acquisition head 8 can cover a different field of view. When the plurality of image acquisition heads 8 work together, image information from different angles can be acquired, thereby effectively improving the accuracy and comprehensiveness of the diagnosis.

[0021] Furthermore, a connection hole is opened at the bottom of the fixing seat 7 , and the hemispherical cover 6 is connected to the connection hole. The hemispherical cover 6 is fixedly connected to the fixing seat 7 through the connection hole opened at the bottom of the fixing seat 7 .

[0022] Furthermore, the outer surface of the hemispherical cover 6 is polished to maintain a low coefficient of friction between it and the rotating ball 5, thereby improving the smoothness of angle adjustment. To further optimize performance, a low-viscosity lubricant is filled between the hemispherical cover 6 and the rotating ball 5 to reduce movement resistance and extend service life.

[0023] Furthermore, the inner wall of the outer cylinder 3 is provided with a guide groove, and the outer circumference of the inner-drive telescopic rod 4 is connected to a guide block, which slides within the guide groove. To enhance the operational stability of the device, the inner wall of the outer cylinder 3 is provided with a guide groove, and the outer wall of the inner-drive telescopic rod 4 is provided with a corresponding guide protrusion. The two cooperate to form a sliding constraint relationship, which can prevent the inner-drive telescopic rod 4 from deviating during movement, ensuring that the imaging assembly always moves on the correct path.

[0024] Optionally, the outer tube 3 is made of medical grade stainless steel, which has good mechanical strength and meets the hygienic requirements of medical devices. Optionally, the inner wall of the hemispherical cover 6 is coated with an anti-reflective coating to reduce the impact of light reflection on image acquisition quality.

[0025] In some embodiments, the internally driven telescopic rod 4 is electrically driven, with its power source integrated within the controller 1. The controller 1 incorporates a micromotor and transmission mechanism, which adjust the telescopic length of the internally driven telescopic rod 4 via control signals, thereby precisely controlling the position of the imaging assembly. Furthermore, the controller 1 is equipped with a manual adjustment button to assist the operator in fine-tuning the angle and position of the imaging assembly during surgery, meeting complex clinical needs.

[0026] It should be noted that when using the imaging device: the operator first holds the device in their hand, activates the device through the controller 1, and inserts the working rod 2 into the temporomandibular joint cavity of the patient to be examined; the operator then triggers the extension of the internally driven telescopic rod 4 through the button on the controller 1. Driven by the micromotor, the internally driven telescopic rod 4 gradually extends along the axial direction of the outer cylinder 3 until the imaging component is completely exposed from the open end of the outer cylinder 3; the operator then uses the angle adjustment function in the controller 1 to send a signal to the drive mechanism between the rotating ball 5 and the semi-spherical cover 6, causing the semi-spherical cover 6 to rotate around the rotating ball 5 to a specified angle; when the semi-spherical cover 6 rotates to the target angle, the multiple image acquisition heads 8 in the fixed seat 7 begin to operate, and the image acquisition heads 8 collect image information at different angles according to the preset direction; the collected image data is transmitted via a signal line to the image processing unit within the controller 1, which integrates and analyzes the received data to generate a complete three-dimensional image model; the operator observes the generated image model through the display screen on the controller 1 and further adjusts the angle or position of the imaging component as needed to obtain more comprehensive diagnostic information.

[0027] Optionally, the angle sensor built into the controller 1 monitors the rotation angle of the hemispherical cover 6 in real time, and feeds back the data to the display screen of the controller 1 for the operator's reference. Optionally, the controller 1 supports switching between multiple working modes, including automatic mode and manual mode. In automatic mode, the controller 1 automatically adjusts the telescopic length of the internal drive telescopic rod 4 and the rotation angle of the hemispherical cover 6 according to a preset program, which is suitable for routine inspection scenarios; in manual mode, the operator can fully control the motion trajectory of the imaging component, which is suitable for complex surgical environments. Optionally, the transmission mechanism of the internal drive telescopic rod 4 adopts a high-precision ball screw structure to ensure smooth and jam-free telescopic movement, effectively improving the practicality and reliability of the device. Optionally, the controller 1 has a built-in battery module to support long-term continuous operation. The battery module is also equipped with a fast charging interface to facilitate replenishing power during surgery.

[0028] It should be noted that in the examination of temporomandibular joint lesions, this multi-angle imaging device has effectively overcome the multiple difficulties in structural exploration, lesion identification and operation implementation by breaking through the limitations of traditional fixed viewing angles, and has realized multi-angle examination of the temporomandibular joint. Its benefits include at least: 1. It is difficult for traditional single-angle arthroscopes to explore the posterior disc area (such as vascular lesions in the double plate area), the medial depression of the condyle, the posterior oblique surface of the articular tubercle and other hidden locations. This device can achieve ±30°~60° pitch, side swing and axial rotation, so that the lens can penetrate into the narrow gaps of the anterior recess, posterior recess and inferior cavity of the superior joint cavity, filling the "observation blind spot" of the traditional viewing angle, avoiding missed diagnosis of lesions due to limited field of view, and breaking through the blind spot of the complex structure of the joint cavity; 2. When the joint moves, the articular disc is displaced, the synovium is displaced, and the synovium is displaced. Incarceration and other lesions change dynamically, and fixed perspectives make it difficult to capture the instantaneous pathological state. This device supports real-time tracking of structural displacement from multiple dimensions such as the sagittal, coronal, and horizontal planes during active or passive joint movement, clearly displaying the abnormal relationship between the primary disc and the condyle and the reduction process of the terminal disc, avoiding misjudgment of the nature of the lesion based solely on static images under traditional single-perspective viewing, and solving the problem of evaluating dynamic lesions; 3. In traditional arthroscopic examinations, doctors often need to try different perspectives by repeatedly inserting and removing the lens or adjusting the patient's position, which may cause articular cartilage abrasions, synovial bleeding, or joint capsule tears. This device can achieve perspective conversion without changing the insertion depth of the lens, reducing physical stimulation to the tissues within the joint, avoiding aggravation of tissue damage due to improper operation, and thereby reducing blindness of operation and the risk of tissue damage.

[0029] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
