Description

[Technical Field]

[0001] This disclosure relates to medical devices. More specifically, this disclosure relates to medical visualization and intubation systems. [Background technology]

[0002] Laryngoscopy may be performed for many reasons, such as to view the internal structures of the pharynx, including the larynx; to facilitate endotracheal intubation using an endotracheal tube (ETT); and to perform biopsy procedures. Generally, direct laryngoscopy refers to the use of a portable laryngoscope to view the internal structures of the pharynx along a direct line of sight, while indirect laryngoscopy refers to the use of a laryngoscope combined with an optical device to visualize the larynx or trachea along an indirect line of sight, such as a mirror or prism, fiber optic stylet, or video laryngoscope. [Overview of the project] [Problems that the invention aims to solve]

[0003] However, for some medical procedures, direct laryngoscopy presents challenges because, due to unplanned scenarios, it is often difficult to visualize directly, such as the anterior vocal cords, obesity, a large tongue, or other irregular airway anatomical features.

[0005] Embodiments of the present disclosure are described herein with reference to the drawings, where the same reference numerals refer to the same parts consistently.

[0006] The embodiments of this disclosure provide a system that extends the use of standard laryngoscopes beyond direct laryngoscopy to video-based indirect laryngoscopy for various medical procedures such as intubation and visualization, and are advantageous in this respect.

[0007] In one embodiment, the laryngoscope enhancement system includes a holder and a video stylet. The holder includes an adjustable mount and an end cap. The adjustable mount is configured to detachably mount an electronic device having a display. The end cap is fixedly coupled to the adjustable mount and defines a central cavity having a lower opening. The end cap is configured to detachably mount the holder to the upper end of the laryngoscope handle, and the lower opening has a diameter that matches the diameter of the upper end of the laryngoscope handle. The video stylet includes several wires, connectors connected to the wires, a flexible portion, a malleable portion, and a video camera connected to one or more of the wires. The connectors are detachably mountable to the electronic device. The flexible portion includes a flexible sheath surrounding the wires. The malleable portion includes a malleable sheath surrounding the malleable wire and the wires. The malleable sheath has a smaller diameter than the flexible sheath.

[0008] Figure 1 shows an IS100 according to an embodiment of the present disclosure.

[0009] In many embodiments, IS100 includes a laryngoscope 110, an electronic device 120, an ETT 130, and an LES 200.

[0010] The laryngoscope 110 includes a handle 112, a blade 114, and a connector 116 for attaching the blade 114 to the lower end of the handle 112. The connector 116 may be fixed or detachable to support blades 114 of various sizes and types. For example, part of the connector 116 may be fixed to or incorporated into the lower end of the handle 112, and the mating portion of the connector 116 may be fixed to or incorporated into the proximal end of the blade 114. The blade 114 may be a Macintosh (curved) blade, a Miller (straight) blade, etc., and generally includes a spatula for passing over the lingual surface of the tongue, a flange for shifting the tongue, and a tip for lifting the epiglottis. The handle 112 is cylindrical in shape with a generally uniform diameter and has an upper end and a lower end.

[0011] The electronic device 120 includes a display 122 for displaying an image from the video stylet 210. More specifically, the electronic device 120 is a mobile portable computer-based electronic device having a touch screen interface and a data / charging port (e.g., a Lightning port, a USB-C port, etc.), such as a smart phone (e.g., Apple iPhone (registered trademark), Samsung Galaxy S / A / Z, etc.), a tablet (e.g., Apple iPad (registered trademark) mini, Samsung Galaxy Tab, etc.). In some embodiments, the electronic device 120 may include a network interface for connecting to a cellular network, a WiFi network, etc.

[0012] The ETT 130 particularly includes a tube 132, a proximal end cap 133 defining a proximal opening, and an inclined distal end 134 defining a distal opening.

[0013] The LES 200 includes a video stylet 210 and a holder 220 for the electronic device 120. The video stylet 210 particularly includes a connector 216 removably attachable to the data / charging port of the electronic device 120, a flexible portion (shown in solid lines) disposed generally outside the tube 132, a malleable portion (shown in dotted lines) disposed generally inside the tube 132, and a video camera 214. The malleable portion of the video stylet 210 is deformable into a preferred shape or curvature and may extend beyond the proximal end of the ETT 130, i.e., outside the tube 132. The combination of the flexible portion and the malleable portion in the video stylet 210 is lightweight and is advantageous in that it can be easily manipulated when advancing the ETT 130 into the patient's airway with one hand.

[0014] FIG. 2 shows an in-situ surgery of the IS 100 according to an embodiment of the present disclosure.

[0015] During the intubation procedure for patient 104, healthcare provider 102 holds the handle 112 of the laryngoscope 110 in one hand and the tube 132 of the ETT 130 in the other hand. More specifically, healthcare provider 102 first manipulates the video stylet 210 to a preferred curvature and then inserts the video stylet 210 into the opening defined by the proximal end cap 133 of the ETT 130 such that the video camera 214 is positioned near the opening defined by the angled distal end 134 of the ETT 130. Once inserted, the ETT 130 generally conforms to the curvature of the malleable portion of the video stylet 210. With the assistance of the laryngoscope 110, healthcare provider 102 introduces the ETT 130 into the mouth of patient 104. After initially placing the ETT 130, healthcare provider 102 uses indirect laryngoscopy to advance the ETT 130 toward the vocal cords of patient 104 while an image of the upper airway captured by the video camera 214 is presented on the display 122 for healthcare provider 102 to view.

[0016] During the visualization procedure for patient 104, the ETT 130 is not used and healthcare provider 102 holds the handle 112 of the laryngoscope 110 in one hand and the video stylet 210 in the other hand. More specifically, with the assistance of the laryngoscope 110, healthcare provider 102 introduces the video stylet 210 into the mouth of patient 104. After initially placing the video stylet 2, healthcare provider 102 uses indirect laryngoscopy to advance the video stylet 210 toward the vocal cords of patient 104 while an image of the upper airway captured by the video camera 214 is presented on the display 122 for healthcare provider 102 to view.

[0017] IS100 is advantageous in that it incorporates the same portable laryngoscope for these procedures, enabling healthcare provider 102 to integrate indirect line-of-sight capabilities while performing the same physical motions as before.

[0018] FIG. 3 shows the ETT 130 according to an embodiment of the present disclosure.

[0019] The ETT130 includes a tube 132, a proximal end cap 133 defining a proximal opening, an inclined distal end 134 defining a distal opening, an air supply connector 136, and an inflatable cuff / balloon 138. An opening 137 (e.g., a "Murphy eye") may also be provided at the distal end of the tube 132 to prevent occlusion if the distal opening defined by the inclined distal end 134 is blocked by mucus or sealed by contact with the patient's tracheal wall.

[0020] The proximal opening allows the video stylet 210 to pass through the tube 132, and the distal opening allows the video camera 214 to extend beyond the inclined distal end 134 (if necessary). Generally, the tube 132 has an outer diameter and an inner diameter, and the ETT 130 has a size (in millimeters) based on the inner diameter of the tube 132, generally ranging from 3.5 (i.e., for infants, an inner diameter of 3.5 mm) to 8.5 (i.e., for adult males, an inner diameter of 8.5 mm) and above. Typically, the size is specified in 0.5 mm increments.

[0021] Figure 4 shows the LES200 according to an embodiment of the present disclosure.

[0022] The LES200 includes a video stylet 210 and a holder 220 for an electronic device 120.

[0023] Generally, the video stylet 210 includes a connector 216 that is detachably attached to the data / charging port of an electronic device 120, a flexible section, i.e., a tube or sheath 212, a malleable section, i.e., a tube or sheath 213, and a video camera 214. In many embodiments, a light source (not shown for clarity) may be placed alongside the video camera 214. In some embodiments, a light source control unit 218 is connected to one or more of the wires to control a light source, such as one or more light-emitting diodes (LEDs).

[0025] Figures 5A, 5B, and 5C show a video stylet 210 according to an embodiment of the present disclosure.

[0026] More specifically, Figures 5A and 5B show plan views of the video stylet 210 according to an embodiment of the present disclosure, and Figure 5C shows cross-sectional views of the flexible portion of the video stylet 210, the malleable portion of the video stylet 210, and the distal end of the video stylet 210 according to an embodiment of the present disclosure.

[0027] The video stylet 210 has a proximal end, a flexible portion 210 F , sheath diameter transition point, malleable portion 210 M , and has a distal end. In many embodiments, the video stylet has an overall length of about 84-107 cm (about 33-42 inches) and a flexible portion 210 F It has a diameter of approximately 7-12 mm and a length of approximately 41-51 cm (approximately 16-20 inches), with a malleable portion of 210. MThe first camera has a diameter of approximately 3-6.5 mm and a length of approximately 41-51 cm (approximately 16-20 inches), while the second camera has a diameter of approximately 3-5.5 mm and a length of approximately 2-5 cm (approximately 1-2 inches).

[0028] Several wires 232 connect the connector 216 to the video camera 214, and the flexible portion 210 F and malleable portion 210 M It extends through. Generally, the number of wires 232 is determined by a specific telecommunications specification, such as Universal Serial Bus (USB). The connector 216 is connected to the wire at the proximal end of the video stylet 210. The sheath 212 surrounds the wire and the flexible portion 210 F It extends along its length, that is, from connector 216 to the sheath diameter transition point. The sheath 213 surrounds the malleable wire and the electric wire, and the malleable portion 210 M It extends along its length, that is, from the sheath diameter transition point to the video camera 214. It is advantageous for sheath 213 to have a smaller diameter than sheath 212 in order to match the small diameter ETT 130.

[0029] In some embodiments, an additional connector 215 may be connected to a wire at the proximal end of the video stylet 210. The additional connector 215 may have a different electrical interface from connector 216 and may be connected to an additional electronic device, such as a smartphone, tablet, or large-screen monitor.
