Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a medical laryngoscope lens device. Background Art

[0002] Due to the deep location and complex physiological structure of the pharynx and larynx, direct visualization is not possible, and a laryngoscope is required for examination or operation during pharyngeal and laryngeal examinations or operations. The laryngeal mask is widely used in general anesthesia surgeries and is an effective means of establishing an artificial airway. Although the insertion of the laryngeal mask is simple, it is difficult to reach the ideal position or encounter difficulties during manual insertion, and sometimes repeated operations or adjustments are required. The factors leading to the failure of laryngeal mask insertion are mainly related to limited mouth opening and the obstruction caused by the sagging of the tongue body. In the prior art, a tongue depressor is often used to assist in the insertion of the laryngeal mask. Although using a tongue depressor to assist in the insertion of the laryngeal mask can press the tongue body towards the floor of the mouth, it cannot effectively increase the patient's mouth opening degree. At the same time, the holding part of the tongue depressor is located in the midline position of the oral cavity, which can also lead to difficulties in inserting the laryngeal mask. If the patient's mouth opening degree is increased solely by the pressure of the tongue depressor, or the laryngeal mask is inserted forcefully, oral mucosal damage may be caused. Therefore, in order to overcome the above drawbacks, it is necessary to provide a laryngoscope that can increase the patient's mouth opening degree and enlarge the insertion channel of the laryngeal mask.

[0027] Preferably, when the L-shaped structure formed by the trigger handle 201 and the spreading handle 202 is triggered, the spreading handle 202 is turned outwards, and the trigger handle 201 moves towards the cavity inside the fixed handle 101, causing the arc-shaped connecting rod 203 to turn outwards. At the same time, the rotating handle 102 turns outwards, opening the patient's larynx.

[0028] Embodiment 2

[0029] Refer to Figures 1 - 4 , which is the second embodiment of the present invention. The difference from the first embodiment is that the fixed handle 101 further includes a hinge ring 101a provided at its end and a receiving groove 101b provided inside it.

[0030] Furthermore, the rotating handle 102 includes a hinge rod 102a provided at its end and a mating hole 102b provided opposite to the hinge rod 102a.

[0031] Preferably, a spring 103a is provided on the side of the extension handle 103, and the other end of the spring 103a is connected to the trigger handle 201. The display screen 104 further includes a wire hole 104a provided at its end. The wire hole 104a penetrates through the fixed handle 101 and the rotating handle 102 and leads into the inside of the rotating handle 102. The trigger handle 201 is movably engaged with the fixed handle 101, and the spreading handle 202 is fixedly formed with the trigger handle 201 to form an L-shaped structure.

[0032] Preferably, the spreading handle 202 includes an arc-shaped block 202a provided at its end and a hinge ring 202b provided inside the arc-shaped block 202a.

When flipping, the connecting part of the fixed handle 101 and the rotating handle 102, the hinge ring one 101a and the hinge rod 102a remain connected. The pushing effect of the spreading handle 202 makes the rotating handle 102 perform a rotating motion, further strengthening the spreading effect. At the same time, the arc-shaped tongue 203a and the arc-shaped block 202a form an effect similar to a duck's bill, achieving a spreading effect on the upper and lower parts of the throat.

[0035] Embodiment 3

[0036] Refer to Figures 1 - 4 , which is the third embodiment of the present invention. On the basis of the first two embodiments: The holding unit 100 includes a fixed handle 101, a rotating handle 102, an extension handle 103 and a display screen 104. The fixed handle 101 is hingedly connected to the rotating handle 102. The extension handle 103 is arranged at the end of the fixed handle 101, and the display screen 104 is arranged at the other end of the extension handle 103. The separation unit 200 includes a trigger handle 201, a spreading handle 202 and an arc-shaped connecting rod 203. The trigger handle 201 and the spreading handle 202 are perpendicularly arranged. The arc-shaped connecting rod 203 is hingedly connected to the end of the spreading handle 202, and the other end of the arc-shaped connecting rod 203 is hingedly connected to the rotating handle 102.

[0037] Preferably, the fixed handle 101 includes a hinge ring one 101a arranged at its end, and a receiving groove 101b arranged inside it. The rotating handle 102 includes a hinge rod 102a arranged at its end, and a mating hole 102b arranged opposite to the hinge rod 102a. A spring 103a is arranged on the side of the extension handle 103, and the other end of the spring 103a is connected to the trigger handle 201. The display screen 104 further includes a wire hole 104a arranged at its end. The wire hole 104a penetrates through the fixed handle 101 and the rotating handle 102 and leads into the inside of the rotating handle 102. The trigger handle 201 is movably matched with the fixed handle 101, and the spreading handle 202 is fixedly formed with the trigger handle 201 to form an L-shaped structure.

[0038] Specifically, the fixed handle 101 provides a space for supporting the entire holding unit 100, while the holding unit 100 provides a fixing space for the extension handle 103, making it more convenient for the doctor to hold. The display screen 104 can clearly show the condition of the patient's throat. The rotating handle 102 is arranged at the end of the fixed handle 101 and is hinged to the fixed handle 101. This structure can reduce the size of the patient's opening when the doctor places the laryngoscope into the patient's mouth, and can expand inside the patient's mouth, reducing the pain of the patient opening their mouth for a long time.

[0039] Preferably, when the L-shaped structure formed by the trigger handle 201 and the spreading handle 202 is triggered, the spreading handle 202 is turned outwards, and the trigger handle 201 moves towards the cavity inside the fixed handle 101, causing the arc-shaped connecting rod 203 to turn outwards. At the same time, the rotating handle 102 turns outwards, opening the patient's larynx.

[0040] In this embodiment, the spring 103a provides elastic force for the reset of the trigger handle 201. The spreading handle 202 is hinged to the rotating handle 102 through the arc-shaped connecting rod 203, jointly forming a hinge mechanism. When in use, when the trigger handle 201 is triggered, the spreading handle 202 drives the inner hinge circular block 203b of the arc-shaped connecting rod 203 to turn outwards, and at the same time drives the lens 203d inside the hollow cavity 203c to extend. The other end of the lens 203d is linearly connected through the wire hole 104a inside the rotating handle 102. When pulled, the lens 203d receives the pulling force of the cable, keeping the direction of the lens 203d stable. When turning, the connecting part hinge ring one 101a and the hinge rod 102a between the fixed handle 101 and the rotating handle 102 remain connected. The pushing effect of the spreading handle 202 makes the rotating handle 102 perform a rotating motion, further strengthening the spreading effect. At the same time, the arc-shaped tongue 203a and the arc-shaped block 202a form an effect similar to a duck's bill, achieving a spreading effect on the upper and lower parts of the larynx.

[0041] In summary, the combination of the fixed handle and the rotating handle of the present invention, during the process of being hinged to the L-shaped connecting rod, by implementing the gripping operation, spreads the arc-shaped dial block, and at the same time inserts the lens inward, enabling medical staff to align the lens with the larynx when spreading the patient's throat, improving the convenience of medical examinations. At the same time, it avoids the excessive expansion of the oral cavity by the traditional duckbill-shaped examination device, reducing the harm to the patient.
