Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a disposable video laryngoscope for small incisions with scarring. Background Technology

[0002] In clinical anesthesia, difficult airways have always been a major challenge for anesthesiologists. While the invention and widespread use of various video laryngoscopes have significantly improved the success rate of intubation in difficult airways, endotracheal intubation remains a significant challenge for patients with small burn scars. Inserting a conventional oropharyngeal airway while the patient is awake can cause extreme discomfort due to the excessive length of the airway and the vomiting reflex triggered by epiglottis stimulation. Although these patients can open their mouths wider than one finger when awake, the scar tissue can prevent them from opening their mouths after anesthesia induction, significantly restricting airway ventilation and making endotracheal intubation even more difficult. Even if the patient can tolerate this, inserting a video laryngoscope after anesthesia induction can be impossible due to the small mouth opening caused by the scar, or the replacement of the video laryngoscope while removing the airway may also fail due to insufficient space. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a disposable scar-specific small-mouth video laryngoscope, which solves the technical problems of not being able to place an oropharyngeal airway when the patient is awake and not being able to open their mouth after anesthesia induction and sleep, and allows for endotracheal intubation after anesthesia induction.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A disposable video laryngoscope for small incisions with scarring is provided, comprising a video laryngoscope, a display screen, a laryngoscope handle, and a camera probe insertion end connected in sequence, and a laryngoscope guide channel for guiding the camera probe insertion end into the laryngoscope. The laryngoscope guide channel includes an outer tube, inside which is a retractable inner channel. The top surface of the outer tube has a cross-sectional area larger than the top plane of the outer tube. A tracheal tube clearance groove is provided on one side of the top plane parallel to the inner channel. An insertion port communicating with the hollow cavity of the inner channel is provided on the surface of the top plane. The inner channel has a hollow cavity that matches the camera probe insertion end. A transparent blind window is provided at the end of the hollow cavity, and a lifting part for lifting the epiglottis is provided at the front end of the transparent blind window.

[0005] Preferably, the inner channel is retractably disposed within the outer tube via a sliding guide. The sliding guide includes a groove on the side of the outer tube and a protrusion on the side of the inner channel. The protrusion is embedded in the groove, and the width of the groove gradually narrows from the end away from the insertion port to the end closer to the insertion port.

[0006] Preferably, the groove is L-shaped and the protrusion is T-shaped, and the protrusion can slide on the surface of the inner channel in a direction perpendicular to the groove.

[0007] Preferably, a small hole for inserting a ties is provided on the top surface and on both sides of the inner channel.

[0008] Preferably, the inner channel is made of transparent rigid plastic, and the outer tube is made of reinforced rubber plastic.

[0009] Preferably, the display screen is connected to the laryngoscope handle via a movable joint, allowing the display screen to rotate 360° around the laryngoscope handle. The display screen has a power switch on its surface and a data cable port on its side.

[0010] Preferably, the front end of the camera probe insertion end is provided with a lighting lamp and a camera.

[0011] Preferably, the outer contour of the outer tube matches the natural curvature of the human oral cavity and pharynx.

[0012] Preferably, the outer sleeve is provided with an extension platform on its side, and the extension platform communicates with the opening of the tracheal tube clearance groove.

[0013] The beneficial effects are as follows: This invention solves various problems that may occur during endotracheal intubation in patients with small scars, such as difficulty in changing the video laryngoscope, tooth damage, and endotracheal intubation failure. When the patient is awake, they only need to hold the disposable video laryngoscope channel for small scars in their mouth; when the patient awakens after anesthesia induction or extubation from general anesthesia and experiences tongue retraction, pushing out the channel inside the laryngoscope can serve as an oropharyngeal airway, solving the problem of ventilation difficulties; after the anesthetic drugs take effect, the video laryngoscope is inserted into the video laryngoscope channel cavity to complete the endotracheal intubation of the difficult airway for patients with small scars. After intubation, the inner channel can be retracted and used as a bite block to assist in the fixation of the endotracheal tube. Attached Figure Description

[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0019] like Figure 1 , 2 As shown, this utility model provides a disposable video laryngoscope for small incisions with scarring. The video laryngoscope includes a display screen 1, a laryngoscope handle 2, and a camera probe insertion end 3 connected in sequence. It also includes a laryngoscope guide channel for guiding the camera probe insertion end 3 into place. The laryngoscope guide channel includes an outer tube 10, within which a retractable inner channel 16 is fitted. The top surface of the outer tube 10 has a top plane 12 with a cross-sectional area larger than the top surface of the outer tube 10. A tracheal tube clearance groove 21 is provided on one side of the top plane 12 parallel to the inner channel 16. An insertion port 18 communicating with the hollow inner cavity 11 of the inner channel 16 is provided on the surface of the top plane 12. The inner channel 16 has a hollow inner cavity 11 that matches the camera probe insertion end 3. A transparent blind window 17 is provided at the end of the hollow inner cavity 11, and a lifting part 13 for lifting the epiglottis is provided at the front end of the transparent blind window 17.

[0020] In one specific embodiment, the front end of the camera probe insertion end 3 is equipped with a lamp and a camera. The display screen 1 is connected to the laryngoscope handle 2 via a movable joint 6, allowing the display screen 1 to rotate 360° around the laryngoscope handle 2 for easy viewing by the operator. The surface of the display screen 1 is equipped with a power switch 4, and the side is equipped with a data cable port 5, which is also equipped with a rubber plug for dust prevention. The data cable port 5 is used to connect a data cable for charging or exporting images and videos stored in the laryngoscope. The laryngoscope handle 2 is equipped with a photo button 7 and a video button 8, allowing the operator to save the desired image with one hand when viewing it. The laryngoscope handle 2 also contains a battery pack and a microprocessor electrically connected to the battery pack. The microprocessor is also electrically connected to the display screen 1, the lamp, and the camera, connecting the various electronic devices into a functional unit. The battery pack provides power to each component, and the camera displays the captured images on the display screen 1 in real time.

[0021] In one specific embodiment, the inner channel 16 is retractably disposed within the outer tube 10 via a sliding guide. The sliding guide includes a groove 14 on the side of the outer tube 10 and a protrusion 15 on the side of the inner channel 16. The protrusion 15 is embedded in the groove 14, and the width of the groove 14 gradually narrows from the end away from the insertion port 18 to the end closer to the insertion port 18. If the patient experiences posterior displacement of the tongue after anesthesia induction or upon awakening after extubation from general anesthesia, the inner tube can be pushed out to form an oropharyngeal airway to assist the patient's ventilation. Specifically, the groove 14 is L-shaped, and the protrusion 15 is T-shaped. The protrusion 15 can slide on the surface of the inner channel 16 in a direction perpendicular to the groove 14. When not in use, the protrusion 15 is in the horizontal rest position of the groove 14, that is, it is stuck at the short end of the groove 14, and the inner channel 16 is retracted inside the outer tube 10. When it needs to be converted into an airway, the protrusion 15 is moved to slide to one end of the long section of the groove 14, and then moved to the other end until it is stuck at the far end of the groove 14. At the far end, the width of the groove 14 is narrower than the width of the protrusion 15, so that the protrusion 15 is stuck. Then, a video laryngoscope can be inserted into the insertion port 18. After the power is turned on, the display screen 1 can display the front section image captured by the camera through the transparent blind window 17 to help the operator locate the intubation tube.

[0022] In one specific embodiment, a small hole 19 for inserting a tether is provided on the surface of the top plane 12 and on both sides of the inner channel 16. After the tether is inserted, it can be used to fix the tracheal tube in the tracheal tube clearance groove 21 that is attached to the side of the top plane 12.

[0023] In one specific embodiment, the inner channel 16 is made of transparent rigid plastic, and the outer tube 10 is made of reinforced rubber plastic. The outer contour of the outer tube 10 matches the natural curvature of the human oral cavity and pharynx. The length of the camera probe insertion end 3 is 9cm. The length of the outer tube 10 is 6cm, the length of the hollow inner cavity 11 of the inner channel 16 is 3cm, and the length of the lifting part 13 is 3cm. The top plane 12 extends 0.5cm from the proximal end of the outer surface of the outer tube 10 towards the sagittal plane to prevent the laryngoscope guide channel from slipping into the mouth.

[0024] In one specific embodiment, the outer sleeve 10 is provided with an extension platform 20 on its side, the extension platform 20 communicating with the opening of the endotracheal tube clearance groove 21, for guiding the endotracheal tube into the patient's mouth.

[0025] The working steps of this utility model are as follows: When a patient with a small scar is awake before anesthesia induction, the patient can have a disposable video laryngoscope channel for small scars placed in their mouth. After induction into sleep, the inner channel 16 of the outer tube 10 is slid out and inserted into the distal end of the outer tube 10 to form an oropharyngeal airway to help the patient breathe. After the anesthetic drugs take effect, the operator holds the video laryngoscope for small scars in their left hand and inserts it into the hollow cavity 11 of the laryngoscope guide channel to expose and observe the glottis through the transparent blind window 17. The operator holds the endotracheal tube in their right hand and inserts it into the patient's mouth along the endotracheal tube clearance groove 21 on the top plane 12 of the laryngoscope guide channel and along the extension platform 20 to complete the endotracheal intubation of the difficult airway for small scars.
