Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a real-time dynamic reduction system for nasal bone fractures under ultrasound guidance. Background Art

[0002] Nasal bone fractures are the most common facial fractures. Without proper early diagnosis and treatment, they can leave a crooked nose and compromise ventilation. While CT has become the standard diagnostic method for nasal bone fractures, limitations such as radiation exposure and poor portability mean that closed reduction of nasal bone fractures still relies primarily on the surgeon's feel and experience, lacking real-time monitoring and objective indicators, resulting in a low overall success rate.

[0003] In recent years, ultrasound diagnosis has been considered an alternative method for diagnosing nasal bone fractures due to its lack of radiation and ease of use. Ultrasound diagnosis of facial fractures dates back to 1990, with studies demonstrating its simplicity, noninvasiveness, and rapidity. Ultrasound tissue harmonic imaging has improved image quality, allowing even delicate bones to be visible under high contrast. Enhanced lateral resolution enables detection of even the smallest dislocations. Recently, ultrasound has been considered a potentially reliable method for diagnosing nasal bone fractures due to its high sensitivity and specificity.

[0004] Currently, there is a lack of a real-time dynamic nasal bone fracture reduction system. Two technical difficulties remain to be overcome: 1. The nasal bone is shaped like a cone, and current ultrasound probes cannot simultaneously display the morphology of both nasal bones. In particular, fractures in the middle of the nasal dorsum are difficult to accurately display, making accurate bilateral nasal bone reduction difficult; 2. The nasal bone reducer is difficult to fully couple with ultrasound due to reflections from the air plane in the middle, making it difficult to dynamically display the position of the nasal bone reducer in real time, thus posing a challenge to accurate reduction. Summary of the Invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a real-time dynamic reduction system for nasal bone fractures under ultrasound guidance, which realizes the complete coupling of the ultrasound probe with the morphology of the bilateral nasal bones, fully and clearly displays the complete morphological characteristics of the bilateral nasal bones, and constructs a nasal bone reduction module that is in close contact with the inside of the nasal cavity, realizes the dynamic coupling of the nasal bone reduction module and the ultrasound system, and can accurately guide and monitor the nasal bone reduction situation in real time.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Component models, material names, connection structures, control methods, algorithms, and other features not explicitly described in this technical solution are considered common technical features disclosed in the prior art.

[0027] The ultrasound-guided real-time dynamic reduction system for nasal bone fractures of the present invention comprises an ultrasound probe module 1, a nasal bone reduction module 2 and a host computer 3, wherein the specific Figure 1 By developing various types of matching layers, this system achieves complete coupling between the ultrasound probe and the morphology of the bilateral nasal bones, fully and clearly displaying the complete morphological characteristics of the bilateral nasal bones. It also constructs a nasal bone repositioning module that is in close contact with the inside of the nasal cavity, achieving dynamic coupling between the nasal bone repositioning module and the ultrasound system, which can accurately guide and monitor the nasal bone repositioning in real time.

[0028] The ultrasound probe module 1 includes an ultrasound probe 11 and a detachable probe matching layer 12 arranged at the detection end of the ultrasound probe 11. The probe matching layer 12 can closely fit the skin surface of the nasal bone; multiple probe matching layers 12 are pre-set, that is, replaceable probe matching layers are used, and the multiple probe matching layers 12 are respectively provided with different fitting matching surfaces.

[0029] The ultrasound probe 11 and probe matching layer 12 are tightly fastened together via a fastener 13. In practice, the ultrasound probe 11 is provided with a fastening protrusion, and the probe matching layer 12 is hingedly connected to the fastener 13, which can be fastened to the fastening protrusion. This structure is easily replaceable and can accommodate different nasal bone and external nasal facial morphologies.

[0030] The nasal bone repositioning module 2 includes a nasal bone repositioner 21 and a water bladder 21 covering the insertion end of the nasal bone repositioner 21. The water bladder 21 is designed to fit tightly within the nasal cavity. Under real-time ultrasonic monitoring, the repositioner is moved upward until the collapsed area is restored. In this technical solution, the nasal bone repositioner 21 is a clamp-type structure, with an insertion end at the front, a cross-hinged portion in the middle, and a gripping end at the rear. A reset spring is connected in the middle of the gripping end. The water bladder 21 covers the insertion end and functions to fit tightly within the nasal cavity.

[0031] The host computer 3 is in communication with the ultrasound probe module 1 and displays the ultrasound fitting image of the nasal bone obtained by the ultrasound probe module 1 and the ultrasound fitting image of the insertion end of the nasal bone resetter 21. The host computer 3 is a conventional computer terminal.

[0032] The ultrasound probe module 1 also includes a first robotic arm 14, the actuator end of which is detachably connected to the ultrasound probe 11. The first robotic arm 14 is in communication with the host computer 3. The nasal bone reduction module 2 also includes a second robotic arm 23, the end of which is gripped by the gripping end of the nasal bone reduction device 21. The second robotic arm 23 is in communication with the host computer 3. The host computer 3 can also control the movements of the first and second robotic arms 14, 23 through a preset program to achieve an automated detection process.

[0033] In practice, the dynamic reduction process is as follows: the patient is instructed to lie supine. After topical anesthesia takes effect, the ultrasound probe module 1 is placed on the collapsed area of ​​the nasal dorsum fracture. Under ultrasound guidance, the nasal bone reduction module 2 is placed on the collapsed area. The reduction device is then moved upward under real-time ultrasound monitoring until the collapsed area is restored. After ultrasound confirms that the fracture ends have been satisfactorily reduced, the nasal bone reduction module 2 is removed. The reduction status is determined through multi-angle visual examination and the bone friction sound during reduction. Once the reduction effect is satisfactory, the affected nasal cavity is packed under real-time ultrasound monitoring.

[0034] Real-time ultrasound guidance can visualize the nasal bone fracture reduction process. Ultrasound can clearly show the strong echo of the reduction forceps in the nasal cavity and guide reduction. After confirming satisfactory reduction, ultrasound can also be used to observe the gauze packing process and guide it, avoiding excessive packing that may affect the position of the fracture ends. If the reduction is unsatisfactory during postoperative follow-up, ultrasound-guided reduction can be repeated.

[0035] It can be seen that the core innovation of this technical solution lies in:

[0036] The ultrasound probe is fully coupled with the morphology of both nasal bones. Existing ultrasound probes cannot simultaneously couple with both nasal bones and can only display the morphology of one side. This is particularly problematic when it comes to displaying fractures in the dorsum of the nose, where the nasal bones fuse. This system, through the development of multiple models of matching layers with a quick-detachable design, achieves personalized coupling of the ultrasound probe with the morphology of both nasal bones, fully and clearly displaying the complete morphological features of both nasal bones. This is crucial for accurately demonstrating complex nasal bone fractures.

[0037] Coupling the nasal bone repositioning module with the ultrasound system: Existing ultrasound probes, due to air interference, cannot clearly and dynamically display the position of the nasal bone repositioner, making it impossible to accurately guide repositioning. This technical solution, with the nasal bone repositioning module in close contact with the nasal cavity, achieves dynamic coupling with the ultrasound system, accurately guiding and monitoring the nasal bone repositioning process in real time.

[0039] Different from the first embodiment, in this embodiment, a buckling protrusion is provided on the probe matching layer 12 , and a fastener 13 is hinged on the ultrasonic probe 11 , and the fastener 13 can be buckled on the buckling protrusion.

[0040] Example 3

[0041] Different from the embodiment 1, both the probe matching layer 12 and the ultrasonic probe 11 are provided with buckling protrusions, and the buckle 13 is buckled on the two buckling protrusions at the same time.
