Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, and particularly to a visual epiglottic inversion pharyngeal treatment instrument. BACKGROUND

[0002] Currently, the non-surgical treatment methods for patients with dysphagia in clinical practice mainly include two types: one is rehabilitation training such as swallowing function training and compensatory skill training, which can improve muscle coordination through intensive exercise of tongue muscles and laryngeal muscles, and help the epiglottis to close better by adjusting the eating posture. The second is drug treatment, which uses drugs according to the cause, such as neurotrophic agents to improve nerve function, or proton pump inhibitors to control gastroesophageal reflux, or muscle relaxants to relieve laryngeal muscle spasm. However, traditional swallowing training requires patients to spend a long time under the supervision of a rehabilitation therapist, which has problems such as insufficient standardization of training and subjective evaluation errors. In addition, compensatory posture adjustment lacks visual feedback, and patients have difficulty in real-time perception of the epiglottic inversion angle. Moreover, drug treatment also has some defects, such as slow onset of neurotrophic agents, limited improvement of acute epiglottic movement disorders, proton pump inhibitors only suitable for reflux-related cases, and muscle relaxants that may cause excessive relaxation of the laryngeal muscles, thereby exacerbating epiglottic closure.

[0003] In order to solve the above problems, the utility model patent with publication number CN220801431U provides a swallowing treatment tool capable of deep pharyngeal stimulation, which comprises a fixed rod, one end of the fixed rod is provided with a handle, the other end of the fixed rod is fixedly connected with a mounting handle, the mounting handle is internally provided with a vibration motor, a plurality of damping springs are uniformly arranged on one side of the vibration motor; a vibration shaft is arranged on one side of the vibration motor, one end of the vibration shaft is mounted with a mounting rod, the mounting handle and the mounting rod are threadedly connected through a second tightening screw thread and a third tightening screw thread, thereby achieving a dismounting function, one side of the mounting rod is fixedly connected with a head end contact seat, the head end contact seat is provided with a concave-convex block, the concave-convex block is beneficial to increasing the oral pharyngeal sensation during vibration treatment; through the above structure, the vibration motor can drive the mounting rod and the head end contact seat to vibrate, and the vibration stimulation is used to stimulate the surface of the patient's tongue and the laryngeal muscles; the vibration frequency and intensity of the tool are adjusted to increase the sensation intensity of the patient's oral pharynx. Although this tool can improve muscle sensation, it still cannot be used for effective treatment of epiglottic movement disorders (such as inversion delay or muscle weakness) during swallowing, which leads to the risk of saliva and food aspiration in patients and may cause complications such as repeated aspiration pneumonia.

The following description of the embodiments with reference to the accompanying drawings is illustrative and intended to explain the present invention, but is not to be construed as limiting the present invention.

[0024] Reference Attachment Figure 1 、 3 4. A visual epiglottal rotation pharyngeal therapeutic device according to this embodiment includes a therapeutic host 1, a therapeutic handle 2, and an image acquisition module. The therapeutic host 1 is provided with an air pump and a control module. The therapeutic handle 2 includes a therapeutic head 2-1, a flexible connecting tube 2-2, a bending component, and a handheld portion. The bending component is provided in the handheld portion. Both the air pump and the bending component are electrically connected to the control module. The two ends of the flexible connecting tube 2-2 are respectively connected to the output end of the bending component and the therapeutic head 2-1. The bending component is used to drive the flexible connecting tube 2-2 to perform bending motion. An annular airbag 2-12 is provided on the outside of the treatment head 2-1. The annular airbag 2-12 is connected to the output end of the air pump through the trachea 2-22. When the treatment head 2-1 reaches the patient's vallecula, the air pump is controlled to inflate the annular airbag 2-12, causing the annular airbag 2-12 to expand and assist in epiglottal reversal. The image acquisition module is located at the head end of the treatment head 2-1 and is used to acquire images of the patient's pharynx; The control module is used to receive and process the pharyngeal image data obtained by the image acquisition module; to control the air pump to inflate and deflate the annular airbag 2-12; and to output execution instructions to the bending component.

[0025] This embodiment integrates an image acquisition module into the treatment head 2-1 of the treatment handle 2 to capture dynamic images of the epiglottis and pharynx in real time, resolving the reliance on subjective assessment in traditional training. Doctors can visually observe the epiglottal reversal angle and delay, and control the timing of airbag inflation and deflation based on the image data, achieving personalized treatment. An annular airbag 2-12 is provided on the outside of the treatment head 2-1. During treatment, when the treatment head 2-1 reaches the vallecula, the air pump controls the inflation of the annular airbag 2-12, thereby applying thrust to the epiglottis. This effectively improves delayed epiglottal reversal or weakened muscle strength, reducing the risk of aspiration. Operation is simple, and the inflation pressure can be dynamically adjusted to suit different patient needs. A curved component and a flexible connecting tube 2-2 are provided to connect the treatment head 2-1, allowing the treatment head 2-1 to adjust its angle in multiple directions within the pharynx, facilitating the positioning of the treatment head 2-1 and the annular airbag 2-12 within the vallecula.

[0026] Preferably, the flexible connecting tube 2-2 includes a silicone outer tube 2-26, a transmission line 2-21 and a silicone inner tube 2-27. The silicone tube is arranged on the outside of the transmission line 2-21 and the silicone inner tube 2-27. A ring-shaped air tube 2-22 is formed between the silicone outer tube 2-26, the transmission line 2-21 and the silicone inner tube 2-27. The image acquisition module is electrically connected to the control module through the transmission line 2-21, and the air tube 2-22 is connected to the ring-shaped airbag 2-12 and the air pump.

[0027] The flexible connecting tube 2-2 is a multi-layer structure, and its outer layer 2-15 is made of a silicone outer tube 2-26, which not only protects the interior, provides flexibility and biocompatibility, and ensures safe contact with the patient's pharynx; by integrating the transmission line 2-21 inside the silicone outer tube 2-26, the image acquisition module and the control module are connected, thereby realizing real-time image transmission; the silicone inner tube 2-27 is used to be sleeved on the outer periphery of the flexible stainless steel wire 2-23 of the bending part, which protects the flexible stainless steel wire 2-23 and plays a certain supporting role, maintaining the structural stability of the flexible connecting tube 2-2 and preventing collapse when bending; by arranging the annular trachea 2-22 around the silicone inner tube 2-27 and the transmission line 2-21, the annular airbag 2-12 is connected to the air pump through the trachea 2-22, ensuring rapid inflation and deflation of the annular airbag 2-12 and controlling the airbag pressure. Thus, the multi-layered flexible connecting tube 2-2 not only avoids entanglement of multiple independent pipelines, improving operational fluidity, but also reduces its outer diameter, enhancing patient comfort and reducing pharyngeal irritation. Furthermore, the multi-layered structure improves the flexible connecting tube 2-2's resistance to breakage, preventing deformation or breakage after long-term use. Both the silicone outer tube 2-26 and the silicone inner tube 2-27 are made of silicone, giving the flexible connecting tube 2-2 excellent bending properties. The bending components enable flexible angle adjustment, ensuring that the treatment head 2-1 reaches the epiglottic vallecula.

[0028] Preferably, refer to the attached Figure 2 The bending component includes a micro-servo 2-31 and a flexible stainless steel wire 2-23. One end of the flexible stainless steel wire 2-23 is wound around the output shaft of the micro-servo 2-31 for 3-5 turns to ensure that the flexible stainless steel wire 2-23 can closely follow the rotation of the micro-servo 2-31 without slipping. To further secure the micro-servo 2-31, medical-grade glue is used to reinforce the winding. The other end of the flexible stainless steel wire 2-23 passes through the silicone inner tube 2-27 and is connected to the treatment head 2-1. Thus, by winding one end of the flexible stainless steel wire 2-23 around the output shaft of the micro-servo 2-31, the micro-servo 2-31 can be used to control the bending direction and degree of the flexible stainless steel wire 2-23, thereby achieving multi-angle adjustment of the treatment head 2-1, adapting to the anatomical differences of different patients and facilitating the annular airbag 2-12 to reach the target position. By passing the flexible stainless steel wire 2-23 through the silicone inner tube 2-27, entanglement with the trachea 2-22 and transmission line 2-21 is avoided. The stainless steel wire has high strength and low ductility, and can provide support for the flexible connecting tube 2-2. By placing the micro-servo 2-31 within the handle, the operator can easily grasp the handle to insert the treatment head 2-1, making operation easier. The micro-servo 2-31 is also relatively small, which does not affect the overall grip comfort.

[0029] Preferably, the curved component further comprises a connecting block 2-25, which is disposed at the end of the treatment head 2-1. The connecting block 2-25 is provided with a connecting hole, the end of the flexible stainless steel wire 2-23 corresponding to the connecting hole, and a locking screw 2-28 is provided on one side of the connecting block 2-25. The end of the locking screw 2-28 extends into the connecting hole, and the locking screw 2-28 locks the flexible stainless steel wire 2-23 to the connecting block 2-25. The provision of the connecting block 2-25 provides a connection structure for the connection between the flexible stainless steel wire 2-23 and the treatment head 2-1. The locking screw 2-28 locks the flexible stainless steel wire 2-23, thereby preventing the treatment head 2-1 from accidentally falling out and preventing the treatment head 2-1 from moving uncontrollably in the patient's pharynx and causing damage. A silicone sheath 2-29 is provided on the outside of the connecting block 2-25 to prevent the connecting block 2-25 and the locking screw 2-28 from directly contacting the patient's pharynx and causing damage to the pharynx.

[0030] Preferably, a plurality of guide rings 2-24 are embedded axially on the inner side of the silicone inner tube 2-27. The guide rings 2-24 are made of medical-grade silicone material, and the other end of the flexible stainless steel wire 2-23 passes through the guide ring 2-24.

[0031] By setting multiple guide rings 2-24 in the inner tube 2-27 of the silica gel, multiple-point constraints are formed on the flexible stainless steel wire 2-23, preventing the flexible stainless steel wire from being radially offset or wound when bending, ensuring that the traction force is transmitted linearly and improving the accuracy of angle control. The guide ring 2-24 also disperses the contact stress between the wire and the tube wall, reducing the risk of wear or fatigue fracture after long-term use.

[0032] Preferably, the handheld part is provided with a handheld controller 2-3, which is electrically connected with the control module, and the handheld controller 2-3 is provided with a first operation button and a second operation button. The first operation button is used to control the movement direction of the bending part, and the second operation button is used to control the inflation and deflation operation of the air pump.

[0033] Preferably, the treatment head 2-1 includes an inner cylindrical body 2-13, a middle layer 2-14, and an outer layer 2-15. The inner cylindrical body 2-13 is made of polyurethane elastomer with a Shore hardness of 40A. The middle layer 2-14 is made of a woven polyester fiber reinforced net, and the outer layer 2-15 is a silica gel anti-sticking layer with a thickness of 0.1mm. The inner cylindrical body 2-13 is provided to provide flexible support, ensuring that the treatment head 2-1 can be placed in the patient's pharynx. The middle layer 2-14 is a woven polyester fiber reinforced net and is coated on the outside of the inner tube body, which is used to enhance the structural strength and limit excessive deformation. The outer layer 2-15 is a silica gel anti-sticking layer with a thickness of 0.1mm, which is coated on the surface of the middle layer 2-14, used to reduce tissue friction and prevent mucosa adhesion.

[0034] Preferably, the outer side of the annular air bag 2-12 is provided with a protrusion 2-16. By setting regular protrusions 2-16 on the outer side of the annular air bag 2-12, the actual contact area between the air bag and the pharyngeal tissue is reduced, and the friction and irritation are reduced.

[0035] Preferably, the host 1 is further provided with a display screen 1-1, operation setting buttons, a pressure sensor, and a pressure relief valve, all of which are electrically connected to the control module. The display screen 1-1 is used to display in real time the pharyngeal image and treatment parameters acquired by the image acquisition module. The pressure sensor is used to monitor the pressure values ​​within the annular airbag 2-12 and the trachea 2-22. The operation setting buttons are used to set the output pressure of the air pump. The pressure sensor and the pressure relief valve are located between the air pump and the trachea 2-22. When the pressure sensor detects that the pressure within the annular airbag 2-12 exceeds a set value, the pressure relief valve releases pressure until the pressure within the annular airbag 2-12 falls below the set value. By providing the display screen 1-1 on the host 1 to display the real-time image acquired by the image acquisition module, the epiglottis flipping dynamics can be displayed, assisting the physician in determining the position of the airbag and the treatment effect. By setting a pressure sensor to monitor the pressure in the annular airbag 2-12 and the trachea 2-22 in real time, combined with the setting of the pressure relief valve, when the pressure of the annular airbag 2-12 exceeds the set value or safety threshold, the pressure relief valve immediately starts to relieve pressure to avoid mucosal compression damage.

[0036] Preferably, the image acquisition module includes a micro camera 2-11 and an LED illumination light source. The LED illumination light source is arranged in a ring around the periphery of the micro camera 2-11 and uses a medical-grade cold light source. The use of the micro camera 2-11 avoids affecting the passability of the treatment head 2-1. By arranging the LED illumination light source around the periphery of the micro camera 2-11, the clarity of the pharyngeal image is improved.

[0037] Treatment host 1 uses an AC-DC power module to power the air pump, which can be a micro-diaphragm air pump with advantages such as small size, low noise, and stable flow rate. The air pump is connected to an N-channel MOSFET driver circuit, which uses PWM (pulse width modulation) to precisely control the air volume. The control module adjusts the duty cycle of the PWM signal based on preset treatment parameters and the pressure value fed back by the pressure sensor, thereby controlling the conduction time of the N-channel MOSFET and accurately adjusting the air volume of the air pump. The pressure sensor can be an MPM281 pressure sensor for real-time monitoring of airway pressure. The pressure sensor is connected to the control module of host 1 via an ADC (analog-to-digital converter) interface, converting the analog signal output by the pressure sensor into a digital signal for processing and analysis by the control module. Based on the collected pressure data, the control module adjusts the air volume of the air pump in real time to ensure that the pressure remains stable within a safe range during treatment. Host 1 also includes a pressure sensor interface circuit that amplifies and conditions the weak analog signal output by the MPM281 pressure sensor for accurate acquisition by the ADC interface. The interface circuit, including components such as operational amplifiers and filter capacitors, effectively suppresses noise interference and improves signal quality. The control module, which can utilize an ARM microcontroller such as the STM32 series, implements system control, data processing, and signal transmission for the entire therapeutic device. This includes receiving input signals from the handheld controller 2-3, processing pressure data collected by the pressure sensor, controlling the air pump's inflation volume and the rotation angle of the microservo 2-31, and driving the display screen 1-1 to display images. To provide a stable operating voltage for circuit modules such as the main control chip, pressure sensor, and microservo 2-31, a voltage stabilization circuit is constructed using either a linear or switching voltage regulator chip.

[0038] The working process of the therapeutic apparatus of this embodiment is as follows: Power-on initialization: After power is turned on, the host 1 performs a self-test to check whether each circuit module and component is working properly. At the same time, the display 1-1 shows the welcome interface and device status information; Parameter setting: The medical staff sets the treatment parameters, such as treatment mode, inflation volume, pressure threshold, etc., through the operation setting buttons 1-2 on the host 1. The control module stores the set parameters in the internal memory.

[0039] Inserting the treatment head 2-1: Slowly insert the treatment head 2-1 through the patient's nasal cavity. During the insertion process, the doctor observes the image captured by the micro camera 2-11 module through the display screen 1-1 and adjusts the position and angle of the treatment head 2-1 in real time by operating the first operation button on the handheld controller 2-3; Treatment process: When the treatment head 2-1 reaches the epiglottic valley, the second operating button on the handheld controller 2-3 is operated to make the control module control the air pump to start inflation according to the preset parameters, and inflate the annular airbag 2-12 outside the treatment head 2-1 through the trachea 2-22. At the same time, the pressure sensor monitors the air circuit pressure in real time and feeds back the air pressure data to the control module. The control module adjusts the inflation volume of the air pump and the working status of the pressure relief valve according to the pressure feedback value to ensure that the pressure of the annular airbag 2-12 is stable within a safe range. During the treatment process, the doctor can adjust the treatment parameters by operating the setting button 1-2 as needed, or adjust the bending angle of the treatment head 2-1 through the control device of the treatment head 2-1; End of treatment: After the treatment is completed, the air pump is controlled to stop working, and after the gas in the annular airbag 2-12 is discharged, the treatment head 2-1 can be slowly pulled out from the patient's nasal cavity; Data saving and shutdown: The host 1 stores the relevant data of the treatment process (such as pressure curve, treatment time, etc.) in the internal memory for subsequent viewing and analysis.
