Description

Technical Field

[0001] The present invention relates to the technical field of airway assessment, and particularly relates to an airway assessment device and an assessment method based on free flap transplantation for oral tumors. Background Art

[0002] The airway, that is, the breathing passage, is composed of the trachea, larynx, nasal passages, etc. to form the respiratory tract. In vertebrates that breathe air, the exhalation and inhalation passage between the pharynx and the lungs is called the airway. The part connected to the pharynx is the trachea. Most tracheas bifurcate into bronchi at the back. The opening of the trachea into the pharynx is called the glottis. The glottis is specialized into the larynx below. The nostrils, which are the passage of breathing air from the outside to the trachea, and from the nasal cavity to the pharynx are the upper respiratory tract. The following airway is the lower respiratory tract. Together, they can sometimes be called the generalized airway. However, in amphibians, air mainly enters through the mouth. In addition, the swim bladder duct (Pneumatic duct) of some bony fish is sometimes also called the airway. After free flap transplantation for oral tumors, it is necessary to evaluate the airway, so an airway assessment device is required.

[0003] Among them, the "airway assessment terminal based on artificial intelligence" disclosed in the Chinese patent with the publication number "CN115381429B" is also an increasingly mature technology. It "performs facial assessment through 3D reconstruction of the collected facial data; performs oral assessment through digital analysis and machine learning of the visible environment of the oral cavity by oral recognition technology; performs dynamic physical assessment through overall dynamic capture of the human head; performs lung function assessment on the airflow changes generated during the entire breathing process through audio frequency analysis and machine learning of the breathing airflow; performs glottis assessment through glottis recognition on the collected anatomical structure image data of the throat of the target object; and finally generates a vocal tract assessment report through comprehensive judgment of the above assessment data and basic information, and performs digital analysis according to the judgment criteria for airway assessment in the existing medical field, so as to provide a comprehensive assessment suggestion for the airway for anesthesiologists. The present invention greatly saves the duration of airway assessment and improves the accuracy of difficult airway diagnosis. It can not only greatly relieve the current practical problem of the shortage of anesthesiology practitioners, but also provide the possibility for accurate diagnosis of difficult airways.

[0004] However, in the actual application process, it is necessary to input its data according to the surgical resection range, flap position, and size, then reconstruct the three-dimensional airway of the patient after surgery, and then conduct analysis and evaluation. However, when the data is not input, it is impossible to protect the keyboard while positioning, and the keyboard cannot be cleaned after removing and adding protection, which will contaminate the keyboard and cause hand contamination of medical staff, making it difficult to keep the instruments clean. At the same time, traditional airway evaluation relies on doctors' experience and lacks multi-dimensional data integration (such as preoperative imaging, intraoperative operation, and postoperative real-time monitoring). The postoperative airway structure changes dynamically due to flap transplantation, and existing devices such as laryngoscopes and bronchoscopes cannot quantitatively predict the extubation risk. Mechanical assistive devices (such as tracheal intubation fixators) are mostly passive structures and lack intelligent linkage with the three-dimensional model of the patient's airway.

When the local pressure exceeds the threshold, the system triggers an alarm and prompts to adjust the intubation depth. The ultrasound probe and the AI ​​smart chip 9010 are linked to automatically locate the suspected edema area and mark it in the three-dimensional model.

[0057] Step 3. Generate an initial 3D airway model through maxillofacial CT. Enter the resection range and flap position / size in real time during the operation and dynamically update the model. Correct the model after the operation by integrating mechanical sensors (pressure, displacement) and endoscopic images. Use 4D printing technology to manufacture a shape memory polymer stent to match the patient's airway model reconstructed by preoperative CT. The stent has a built-in serpentine circuit sensor network that can adaptively adapt to postoperative anatomical changes within 48 hours after the operation as the temperature changes, avoiding compressive injuries caused by traditional rigid probes.

[0058] Working principle: When in use, rotate the threaded rod 701, then adjust the position of the support plate 702 on the threaded rod 701. Subsequently, the support plate 702 contacts the ground to support the device. When the bottom of the protective plate 501 fits into the U-shaped groove on the inner bottom wall of the housing 500, one end of the insertion rod 504 abuts against one side of the protective plate 501. When data needs to be input through the keyboard 4, pull up the protective plate 501. When the slot on the protective plate 501 coincides with one end of the insertion rod 504, the tension spring 506 resets the insertion rod 504 on the sliding plate 505, so that one end of the insertion rod 504 is inserted into the slot on one side of the protective plate 501. While the protective plate 501 moves, the surface of the keyboard 4 can be wiped. Subsequently, data is input through the keyboard 4. When the keyboard 4 needs to be protected, pull the sliding plate 505 on the pull rod 507, and one end of the insertion rod 504 separates from one side of the protective plate 501. The protective plate 501 drops and contacts the inner bottom wall of the housing 500, thus realizing the protection of the keyboard 4. The data is processed by the host 3. Subsequently, when data detected by an external instrument needs to be transmitted to the host 3, insert one end of the output line of the external scanning instrument into the inside of the connecting pipe 600, then tighten the screw ring 604. The pressing ring 605 on one side of the screw ring 604 squeezes one side of the annular airbag 601. The gas in the annular airbag 601 enters the inside of the movable cavity, thereby squeezing the clamping rod 603 on one side of the piston plate 602, so that one end of the clamping rod 603 is clamped to the surface of the output line, realizing the positioning connection of the output line. Subsequently, the data is transmitted into the host 3 for analysis and evaluation, and the evaluated information is displayed on the evaluation display screen 2.
