Description

Technical Field

[0001] This invention belongs to the field of medical assistive devices, specifically a bronchial tube closure device. It utilizes integrated innovation to solve the above-mentioned clinical problems by incorporating a balloon imaging monitoring module and a bendable design to expand its applicability. This allows for flexible adjustment of the angle to the required position during intubation and real-time monitoring of the balloon closure status, significantly reducing the risk of surgical interruption. Prior Technology

[0002] Note that a endotracheal tube is a tube inserted into the trachea. Its main purpose is to establish and maintain a clear airway and ensure adequate exchange of oxygen and carbon dioxide, thereby ensuring sufficient oxygenation and ventilation for the patient. It is inserted through the mouth or nose, travels along the trachea to the bronchi, and then supplies air. However, in the past, during intubation, medical personnel had to ensure the endotracheal tube was accurately inserted into the designated position. Therefore, an imaging monitor was used to observe and ensure the correct insertion position and depth. However, patient movement or violent shaking during transport could cause the endotracheal tube to be pulled out or even dislodged.

[0003] Therefore, the so-called endobronchial blocker has appeared on the market. It is similar to the endobronchial tube in terms of its setting method. However, because the endobronchial blocker has an inflatable cuff at the front end for fixing to the bronchial wall, it can only be placed inside the endobronchial tube to reach the set position in the bronchus. After reaching the set position, it is inflated to fix it to the inner wall of the bronchus. However, during thoracic surgery, the endobronchial blocker cuff often shifts due to surgical pulling, causing the interruption of the single-lung breathing state and requiring readjustment of the blocker position. Therefore, it is still necessary to use it in conjunction with an imaging bronchoscope. The endobronchial blocker has a bend at the front end as a guide for insertion, allowing medical personnel to rotate and change the direction. However, the existing endobronchial blocker has two major drawbacks: (1) It does not have an imaging bronchoscope function. If it is necessary to confirm the insertion position or reposition it during surgery, a small bronchoscope must be placed for confirmation. However, the narrow space inside the trachea often causes inconvenience in operation. According to clinical statistics, more than 90% of physicians believe that this problem exists; (2) The existing products are made of plastic and cannot be rotated flexibly. Readjustment during the operation often causes the operation to be interrupted. Therefore, the medical community urgently needs to improve these defects. Summary of the Invention

[0004] One objective of this invention is to provide an endobronchial tube closure device that utilizes an operating box, an extension tube, a closure cuff, an inflation module, and a bend module. The operating box, in conjunction with the extension tube and the bend module, controls the movement and orientation of the closure cuff during placement. Furthermore, the cuff imaging monitoring module provides internal illumination and image capture to confirm the correct positioning of the extension tube and the closure cuff within the bronchus. The inflation module supplies air to the closure cuff, causing it to expand and lock securely within the bronchus. During the surgical procedure, the cuff imaging monitoring module continuously monitors the closure status of the closure cuff, preventing problems and minimizing surgical interruptions, significantly improving the accuracy, stability, and safety of closure device placement.

[0005] To achieve the above objectives, the present invention provides an endobronchial tube closure device for insertion into the bronchus for medical procedures.

This invention can also include an airbag image monitoring module, comprising an illumination element, an image capturing element, and a control signal element. The illumination element and the image capturing element are electrically connected to the control signal element. The illumination element and the image capturing element are spaced apart on the mounting portion. The control signal element is located inside the control box at the position corresponding to the connection hole. In this way, the airbag image monitoring module and the elbow module control the extension tube to enter a predetermined position of an air tube. The inflation module inflates the locking airbag to form a locking and fixed position, and monitors the locking status of the locking airbag at any time. In addition, to increase the safety and convenience of its operation, this invention also has an alarm module. The alarm module is located on the surface of the operating box and is electrically connected to the image capturing element. The alarm module includes an image analysis element, an image database, at least one light warning device and a buzzer. After the image analysis element analyzes the image obtained by the image capturing element and compares it with the image database, if an abnormality occurs, the light warning device and the buzzer will issue an alarm.

[0006] In one embodiment, the elbow module of this invention includes two pull ropes, a control handle, and a turntable. Each pull rope is respectively inserted into each second channel, with one end fixed to the first end, and the other end passing through the connecting hole and connected to the two mounting holes of the turntable. The control handle is linked to the turntable. By operating the control handle, the two pull ropes can be extended and retracted respectively, so that the extension tube can achieve the effect of bending or straightening. Furthermore, the two mounting holes are located at two opposite corners of the turntable, with the two opposite corners forming a 180-degree angle, and each opposite corner forming a 90-degree angle with the pull rope entry point.

[0007] In another embodiment, the control box of this invention includes a main body, a first side cover, and a second side cover. The first side cover is assembled onto one side of the main body to form the first accommodating space, and the second side cover is assembled onto the other side of the main body to form the second accommodating space. It should be noted that the extension tube of this invention extends out of the control box from the second accommodating space, and the extension tube has a first channel and a pair of second channels inside. The pair of second channels are respectively located on opposite sides of the first channel. During installation, the two second channels are located in the horizontal direction corresponding to the operation of the control box. In addition, an air supply tube is used in conjunction, which extends into the extension tube along the second accommodating space, and one end of the air supply tube is located at the first end to form an air supply port. The air supply port is separated from the locking airbag to supply air over the locking fixing point.

[0010] To ensure that your review committee can clearly understand the content of this work, please refer to the following explanations and illustrations.

[0011] Please refer to Figures 1, 2, 3-8, and 9-11, which are exploded perspective views of the preferred embodiment of this invention, as well as perspective views of its assembled appearance, state diagrams and structural diagrams corresponding to various operations, and diagrams corresponding to monitoring various closure states. As shown in the above figures, the bronchial tube closure device 1 of this invention includes an operation box 11, an extension tube 12, a closure airbag 13, an inflation module 14, a bend module 15, and an airbag image monitoring module 16, for insertion into the bronchus 2 for medical procedures.

[0012] The operation box 11 has a first accommodating space 111 and a second accommodating space 112 inside, with a connecting hole 113 between the first accommodating space 111 and the second accommodating space 112. The first accommodating space 111 has an operation hole 114 relative to the top of the operation box 11 and a connecting hole 115 relative to the bottom of the operation box 11. It should be noted that the operation box 11 of this invention includes a body 116, a first side cover 117 and a second side cover 118. The first side cover 117 is assembled to one side of the body 116 to form the first accommodating space 111, and the second side cover 118 is assembled to the other side of the body 116 to form the second accommodating space 112.

[0013] The extension tube 12 is connected to the second accommodating space 112, and the extension tube 12 has a first channel 121 and at least one second channel 122 inside, and the extension tube 12 has a first end 123 and a second end 124. In addition, the extension tube 12 has a mounting part 125 on the outer surface near the first end 123. It should be noted that the extension tube 12 of this invention passes through the second accommodating space 112 and exits the operation box 11. In its specific implementation, the extension tube 12 has a first channel 121 and a pair of second channels 122 inside the extension tube. The pair of second channels 122 are respectively located on opposite sides of the first channel 121. During installation, the two second channels 122 are located in the horizontal direction corresponding to the operation of the operation box 11.

[0014] The locking airbag 13 is disposed on the surface of the first end 123, so that the locking airbag 13 is connected to the first channel 121, and the locking airbag 13 remains in a contracted state during movement.

[0015] The inflatable module 14 has an inflation tube 141 connected to the first channel 121 of the second end 124 to deliver gas to the locking airbag 13 to inflate its volume.

[0016] The elbow module 15 includes a pulling means 151 and a control handle 152. The pulling means 151 is connected from the inside of the extension tube 12 to the first end 123 and is linked with the control handle 152. By operating the control handle 152, the extension tube 12 can be bent or straightened. In specific implementation, the elbow module 15 includes two pull ropes 1511, a control handle 152, and a turntable 1512. Each pull rope 1511 is respectively inserted into each second channel 122, with one end fixed to the first end 123 and the other end passing through the connecting hole 113 and connected to... Within the two mounting holes 15121 of the turntable 1512, the control handle 152 is linked to the turntable 1512. By operating the control handle 152, the two pull ropes 1511 can be extended and retracted respectively, so that the extension tube 12 can achieve the effect of bending or straightening. Furthermore, the two mounting holes 15121 are located at two opposite corners of the turntable 1512, and the two opposite corners are 180 degrees apart, and each opposite corner is 90 degrees from the entry point of the pull rope 1511. In addition, the operating hole 114 is linearly opened, and the control handle 152 swings along the extension direction of the operating hole 114.

[0017] The airbag image monitoring module 16 includes an illumination element 161, an image capturing element 162, and a control signal element 163. The illumination element 161 and the image capturing element 162 are electrically connected to the control signal element 163. The illumination element 161 and the image capturing element 162 are spaced apart on the mounting portion 125. The control signal element 163 is located inside the operation box 11, corresponding to the connection hole 115. The airbag image monitoring module 16 has two illumination elements 161 spaced apart, both of which are LED lighting sources. The image capturing element 162 is a complementary metal-oxide-semiconductor (CMOS) chip. For convenient connection and monitoring, the bronchial tube closure device 1 further includes a signal interface 164 electrically connected to the control signal element 163. The signal interface 164 is located on the connection hole 115 for connecting to a monitoring screen 165.

[0018] To enhance safety and convenience during operation, the endobronchial tube closure device 1 of this invention further includes an alarm module 17. The alarm module 17 is located on the surface of the operating box 11 and electrically connected to the image capturing element 162. The alarm module 17 includes an image analysis element 171, an image database 172, at least one light warning device 173, and a buzzer 174. After the image analysis element 171 analyzes the image obtained by the image capturing element 162 and compares it with the outline circumference of the airbag 13 in the image database 172, an abnormality occurs when the exposed circumference of the airbag 13 is greater than one-sixth to one-twelfth, and an alarm is issued through the light warning device 173 and the buzzer 174.

[0019] In addition, this invention provides an air supply tube 18 for the convenience of surgery. It passes through the first channel 121 inside the extension tube 12 along the second accommodating space 112. One end of the air supply tube 18 is located at the first end 123 to form an air supply port 181. The air supply port 181 is separated from the locking airbag 13 so as to supply air over the locking fixation point. Figures 9-11 are schematic diagrams of the monitoring of the closure state of this invention. Figure 9 shows the fully closed state. When the image analysis element 171 analyzes and compares the tissue on the surface of the bronchus 2 and finds that it is tightly bound by the closure airbag 13, the circumference of the exposed outline of the airbag 13 is less than 1 / 24 to 0, indicating that it is blocked by the tissue on the surface of the bronchus 2, making the outline of the airbag 13 almost invisible. Therefore, the outline of the airbag 13 in Figure 9 is represented by a dashed line, so the alarm module 17 will not issue any warning notification. Figure 10 shows the unclosed state. When the image analysis element 171 analyzes and compares the tissue on the surface of the bronchus 2 and finds that the closure airbag 13 has slightly shifted, the airbag is exposed. If the circumference of the airbag 13 is greater than one-twelfth, the alarm module 17 will illuminate one of the indicator lights 173 and emit a low-frequency warning signal with the buzzer 174 to remind medical personnel to pay attention or make adjustments. Figure 11 shows a state of significant deflation or displacement. When the image analysis element 171 analyzes and compares the circumference of the airbag 13 and shows more than one-sixth, the bronchus 2 cannot be completely closed. At this time, the alarm module 17 will illuminate the two indicator lights 173 and emit a high-frequency warning signal with the buzzer 174 to notify medical personnel that the airbag 13 has shifted significantly, deflated, or that the inflation device is damaged, making surgery impossible.

[0020] Accordingly, the endobronchial tube closure device 1 of this invention utilizes the extension tube 12 combined with the closure cuff 13 and the cuff image monitoring module 16 for internal illumination and image acquisition during intubation. The cuff image monitoring module 16 is operated through the operation box 11, and the inflation module 14 provides air to the closure cuff 13 to expand its volume. The cuff image monitoring module 16 further confirms whether the movement and direction of the extension tube 12 are correct, and the elbow module 15 controls the correct position of the extension tube 12 entering the bronchus 2. After the closure cuff 13 is inflated by the inflation module 14, it forms a lock and fixation at the predetermined position of the bronchus 2. The locking status of the closure cuff 13 is monitored at any time to avoid problems and reduce surgical interruptions, thereby improving the accuracy, stability and safety of intubation surgery.
