Nasal laryngoscope convenient for angle adjustment

Abstract

The invention relates to a nasal laryngoscope convenient for angle adjustment, which comprises a nasal laryngoscope body and an injection structure, and the nasal laryngoscope body is movably connected with the injection structure; a support structure for supporting the injection structure and an operation structure for controlling the injection or suction operation of the injection structure are arranged on the outer side of the injection structure; the operation structure is arranged on the first surface and / or the second surface of the supporting structure; the lower end of the supporting structure is provided with a regulating structure for regulating the heights and inclination angles of the supporting structure and the injection structure; the operation structure comprises an operation assembly, a first threaded rod and a threaded outer sleeve, the operation assembly is connected with the first threaded rod, the outer part of the threaded outer sleeve is sleeved with the outer side of the first threaded rod, and the threaded outer sleeve is connected with the injection structure through a connecting assembly; a protective shell used for limiting the threaded outer sleeve is arranged on the outer side of the operation structure, and the protective shell and the second supporting plate are integrally connected. A moving cavity only allowing the threaded outer sleeve and the connecting assembly to move is formed in the protective shell.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a nasal laryngoscope which is convenient for angle adjustment. Background technique [0002] Endoscopes generally refer to medical instruments that enter the human body through various channels to observe the internal conditions of the human body. The endoscope can be used to see lesions that cannot be seen on X-rays, so it is very useful for doctors. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the stomach, and formulate the best treatment plan accordingly. [0003] Fiberoptic nasopharyngoscope is a medical device for examining the nasopharynx, pharynx and larynx, and can perform biopsy, surgical treatment of vocal cord nodules or small vocal cord polyps, and removal of foreign bodies in the pharynx. It is a kind of optical fiber equipment. During the detailed inspection of the larynx, the lesion can be magnified thous...

Problems solved by technology

Clinically, there is also a demand for injecting medicine to the target position and aspirating body fluid. Although the nasopharyngoscope in the prior art has the function of injecting medicine, it still has the following defects: 1. The hand is easy to slide when using the medicine syringe, The force is unstable, which leads to problems such as poor control of the drug injection process; 2. Because the nasopharyngoscope is a flexible endoscope, the place where the drug is sprayed is prone to slip during the drug injection process

[0004] In addition, the endoscope is generally directly inserted into the patient's body for inspection, but due to the complex situation in the patient's body, the endoscope will sometimes be driven to shift, resulting in the use of the endoscope being easily out of control and the use effect is not good; During laryngoscopy, the patient needs to take a sitting or supine position according to the position of the foreign body. When sitting or supine, the patient will also have different position changes. At this time, the position of the drug syringe also needs to be changed according to the position of the patient to avoid manipulation. During the process, the nasopharyngoscope causes damage to the target position or the route position, which increases the pain of the patient; in order to facilitate inspection, clinically, it is usually effectively fixed and supported by a support frame, but the existing support frames also have the following defects: clinically used supports It is inconvenient to freely adjust the height and angle of the support frame; different patients and different environments will have specific requirements for the height and angle of the support frame. It may delay the patient's condition and cause irreversible effects; at the same time, it may also damage the tissue at the target position and passing position of the endoscope
