Description

Technical Field

[0001] This utility model relates to a video laryngoscope, and more particularly to a video laryngoscope with a probe. Background Technology

[0002] Existing probe laryngoscopes generally include a probe assembly and a cannula assembly, with the cannula assembly and probe assembly primarily connected and fixed by a locking mechanism. However, due to inaccurate consistency between the cannula length and the probe length, and the existence of a certain gap between the cannula assembly's sleeve and the probe assembly's connector after the locking mechanism is engaged, these gaps and length errors create a void between the end of the cannula and the end of the probe after they are fitted together. This void allows light to be emitted or leaked, affecting the image quality of the camera at the probe end and resulting in unclear video. Utility Model Content

[0003] The purpose of this invention is to provide a video laryngoscope with a probe that is easy to assemble and provides clearer images.

[0004] To achieve the above objectives, the present invention provides a video laryngoscope with a probe, comprising a probe assembly and a cannula assembly. The probe assembly includes a connector and a probe, one end of which is connected to the connector. A protrusion is provided on the outer side of the connector near the probe end. The cannula assembly includes a sleeve and a cannula, one end of which is connected to the sleeve. A spiral locking groove is provided on the sidewall of the sleeve around a central axis, and a guide groove is provided on the inner sidewall of the sleeve, connecting to the beginning of the locking groove. When the sleeve is fitted onto the connector, the protrusion enters the locking groove through the guide groove and slides within it. The cannula is fitted over the probe. When the cannula rotates relative to the connector, it can approach the connector under the guidance of the locking groove and the protrusion, so that the end face of the cannula contacts the end face of the probe.

[0005] Compared with the prior art, this utility model provides a protrusion on the outside of the probe connector, a spiral locking groove around the central axis on the side wall of the sleeve, and a guide groove connecting the starting end of the locking groove on the inner side wall of the sleeve. Therefore, by allowing the protrusion to enter the locking groove along the guide groove, it can slide within the locking groove. Thus, by simply rotating the sleeve, the sleeve can move towards the connector under the guidance of the locking groove and the protrusion, thereby fitting closer to the connector. This allows the end of the probe to be closer to the end face of the sleeve, ensuring that the end face of the sleeve and the end face of the probe can contact each other without gaps. This prevents light leakage and reflection caused by gaps between the camera at the end of the probe and the end face of the sleeve, which would affect image clarity. Therefore, this utility model has the advantages of convenient assembly and clearer images.

[0006] Preferably, a camera is provided at the end of the probe, and the camera presses against the end face of the sleeve. This allows for clear image recording and avoids gaps between the camera and the end of the sleeve, thus preventing light leakage or reflection and improving image clarity.

[0007] Specifically, the end face of the sleeve is provided with a light-transmitting lens, which is in contact with the camera.

[0008] Preferably, the light-transmitting lens is made of nylon material. By using a lens made of nylon material, light leakage or reflection can be effectively avoided, further improving image clarity.

[0009] Preferably, the sleeve is made of nylon material. By using a nylon sleeve, expansion and contraction of the sleeve can be prevented, thus ensuring that the end of the probe is in contact with the end of the sleeve each time the sleeve is fitted over the probe.

[0010] Preferably, the inner bottom surface of the sleeve is provided with a buffer pad that can press against the connector. By providing a buffer pad, it is possible to ensure a stable and safe connection between the sleeve and the connector, and also to provide a certain buffer space when the probe is pressed against the sleeve, thus ensuring the reliability and safety of the connection.

[0011] Preferably, the outer wall of the end of the sleeve away from the tube has raised or recessed textures. This facilitates the rotation of the sleeve and improves ease of use.

[0012] Preferably, the video laryngoscope with probes further includes a display device connected to the connector.

[0013] Specifically, the display device and the connector are detachably connected via a connector. This makes the assembly of the display device more convenient and quick.

[0014] Specifically, the display device includes a bracket, a display, and a power supply. The display is mounted on the bracket, the bracket has a battery compartment, and the power supply is detachably mounted in the battery compartment. Attached Figure Description

[0022] To explain in detail the technical content, structural features, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0023] like Figures 1 to 5As shown, the video laryngoscope 100 with a probe of this utility model includes a probe assembly 1 and a cannula assembly 2. The probe assembly 1 includes a connector 11 and a probe 12, one end of which is connected to the connector 11. The connector 11 has two protruding protrusions 111 on its outer side near the end of the probe 12, arranged symmetrically. Each protrusion 111 is a cylindrical pin. The cannula assembly 2 includes a sleeve 21 and a cannula 22, one end of which is connected to the sleeve 21. The sidewall of the sleeve 21 has a spiral locking groove 211 around its central axis, and the inner sidewall of the sleeve 21 has a guide groove 212 that connects to the beginning of the locking groove 211. The guide groove 212 extends to the edge of the sleeve 21. When the sleeve 21 is fitted onto the connector 11, the protrusion 111 enters the locking groove 211 through the guide groove 212 and is slidably disposed within the locking groove 211. The sleeve 22 is fitted over the probe 12; when the sleeve 22 rotates relative to the connector 11, it can approach and tighten onto the connector 11 under the guidance of the locking groove 211 and the protrusion 111. When the protrusion 111 slides to the end of the locking groove 211, the sleeve 22 is completely fitted and fixed over the connector 11, and the end face of the sleeve 22 contacts the end face of the probe 12. The sleeve 22 is made of nylon material. By using a sleeve made of nylon material, the nylon material is not easily stretched, which can prevent the sleeve 22 from expanding or contracting, thus ensuring that the end of the probe 12 contacts the end of the sleeve 22 every time the sleeve 22 is fitted over the probe 12.

[0024] Please see again Figure 3 The probe 12 has a camera 3 at its end, and the end face of the sleeve 22 has a light-transmitting lens 221. The camera 3 presses against the light-transmitting lens 221 on the end face of the sleeve 22. This avoids a gap between the camera 3 and the light-transmitting lens 221, thereby preventing light leakage or reflection, improving image clarity, and thus recording the image clearly. Specifically, the light-transmitting lens 221 is made of nylon material. By using a lens made of nylon material, the high light transmittance of nylon can effectively prevent light leakage or reflection, further improving image clarity.

[0025] Please see again Figure 3 The inner bottom surface of the sleeve 21 is provided with a buffer pad 213 that can press against the connector 11. By setting the buffer pad 213, it can be ensured that the sleeve 21 and the connector 11 can be stably and safely connected, and it can also provide a certain buffer space when the probe 12 presses against the sleeve 22, thus ensuring the reliability and safety of the connection.

[0026] like Figure 4 As shown, the outer wall of the end of the sleeve 21 away from the sleeve 22 has protruding or recessed textures 214. This facilitates the rotation of the sleeve 21 and improves ease of use.

[0027] For example Figure 6 As shown, the video laryngoscope 100 with a probe also includes a display device 4, which is connected to the connector 11. The display device 4 and the connector 11 are detachably connected via a connector 5, which is a Remer connector. This connector structurally connects the display device 4 to the connector 11 and electrically connects the display device 4 to the camera on the probe 12, making the assembly and connection of the display device 4 more convenient and faster. Specifically, the display device 4 includes a bracket 41, a display 42, and a power supply. The display 42 is mounted on the bracket 41, which has a battery compartment 43. The power supply is detachably located in the battery compartment 43. The bracket 41 has a rotating joint 411, allowing the display 42 to be adjusted for easy viewing of the images. Figure 7 As shown, the display of this utility model can also be a large-screen display 42 or a small-screen display 42', and these displays can be connected to the probe assembly 1 through the connector 5.

[0028] Compared with the prior art, this utility model provides a protrusion 111 on the outside of the connector 11 of the probe 12, a spiral locking groove 211 around the central axis on the side wall of the sleeve 21, and a guide groove 212 connecting the starting end of the locking groove 211 on the inner side wall of the sleeve 21. Therefore, by allowing the protrusion 111 to enter the locking groove 211 along the guide groove 212, it can slide within the locking groove 211. Thus, simply rotating the sleeve 21 allows the sleeve 21 to slide within the locking groove 211 and the guide of the protrusion 111. With the cooperation of the probe 12, it moves towards the connector 11 and fits closer to the connector 11. This allows the end of the probe 12 to be closer to the end face of the sleeve 22, ensuring that the end face of the sleeve 22 and the end face of the probe 12 can contact each other without gaps. This prevents light leakage and reflection caused by gaps between the camera 3 at the end of the probe 12 and the end face of the sleeve 22, which would affect the clarity of the image. Therefore, this invention has the advantages of easy assembly and clearer images.

[0029] The structure of the display 42 and the Remer connector involved in the video laryngoscope 100 with probe of this utility model are well known to those skilled in the art, and will not be described in detail here.

[0030] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
