Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a medical laryngoscope lens device. Background Art

[0002] Since the throat is located deep and has a complex physiological structure, it cannot be directly viewed. When inspecting or operating the throat, it is necessary to use a laryngoscope to inspect or operate. Laryngeal masks are widely used in general anesthesia surgery and are an effective means of establishing an artificial airway. Although the laryngeal mask is easy to insert, it is difficult to reach the ideal position or encounter insertion difficulties when inserting the laryngeal mask barehanded, and sometimes repeated operations or adjustments are required. The factors for the failure of laryngeal mask insertion are mainly related to the limited mouth opening and the obstruction of the tongue sagging. In the prior art, tongue depressors are often used to assist the insertion of laryngeal masks. Although the tongue depressor can press the tongue to the bottom of the mouth when assisting the insertion of the laryngeal mask, it cannot effectively increase the patient's mouth opening. At the same time, the tongue depressor grip is located in the midline of the oral cavity, which can also lead to difficulty in inserting the laryngeal mask. If the tongue depressor pressure is blindly used to increase the patient's mouth opening, or the laryngeal mask is inserted violently, it can cause damage to the oral mucosa. Therefore, in order to overcome the above-mentioned drawbacks, it is necessary to provide a laryngoscope that increases the patient's mouth opening and enlarges the laryngeal mask insertion channel. Summary of the invention

[0038] Specifically, the fixed handle 101 provides a supporting space for the entire holding unit 100, and the holding unit 100 provides a fixed space for the extended handle 103, making it easier for the doctor to hold the device, while the display screen 104 can clearly display the condition of the patient's throat. The rotating handle 102 is disposed at the end of the fixed handle 101 and is hingedly connected 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, stretch the patient's mouth, and reduce the pain of the patient opening their mouth for a long time.

[0039] Preferably, the L-shaped structure formed by the trigger handle 201 and the opening handle 202 is turned outward when the trigger handle 201 is triggered, and the trigger handle 201 moves toward the cavity inside the fixed handle 101, so that the arc connecting rod 203 is turned outward, and the rotating handle 102 is turned outward, so that the patient's throat is turned outward.

[0040] In this embodiment, the spring 103a provides elastic force for the reset of the trigger handle 201, and the opening handle 202 is hingedly connected to the rotating handle 102 through the arc connecting rod 203, and together they form a hinge mechanism. When the trigger handle 201 is used, the opening handle 202 drives the inner hinged round block 203b of the arc connecting rod 203 to flip outward, and at the same time drives the lens 203d inside the hollow cavity 203c to extend, and the other end of the lens 203d is inserted into the thread hole 103 on the inner side of the rotating handle 102. 4a is linearly connected. When pulled, the lens 203d receives the pulling force of the cable, and the direction of the lens 203d remains stable. When flipped, the connection between the fixed handle 101 and the rotating handle 102, the hinge ring 101a and the hinge rod 102a remain connected, and the pushing effect of the opening handle 202 makes the rotating handle 102 rotate, so that the opening effect is further enhanced. At the same time, the arc-shaped tongue 203a and the arc-shaped block 202a form a duckbill-like effect, realizing the opening effect on the upper and lower parts of the throat.

[0041] In summary, the combination of the fixed handle and the rotating handle of the present invention can realize the gripping operation during the articulation with the L-shaped connecting rod, so that the arc-shaped shift block is stretched open and the lens is moved inward at the same time, so that the medical staff can aim the lens at the throat when stretching the patient's throat, thereby improving the convenience of medical examinations and avoiding the excessive expansion of the oral cavity by traditional duckbill-shaped inspection devices, reducing damage to patients.
