Nasal laryngoscope with injection administration function and convenient angle adjustment function

Abstract

The invention relates to a nasal laryngoscope with an injection administration function and convenient angle adjustment. The nasal laryngoscope comprises a nasal laryngoscope body and an injection structure, and the nasal laryngoscope body is movably connected with the injection structure; a supporting 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; a regulation and control structure for regulating the heights and inclination angles of the supporting structure and the injection structure is arranged at the lower end of the supporting structure; the regulation and control structure comprises an adjusting plate arranged at the lower end of the supporting structure, a rack belt moving relative to the adjusting plate, a first gear arranged at the upper end of the inner side of the rack belt, a second gear arranged at the lower end of the inner side of the rack belt and a power structure connected with the second gear; and the power structure controls whether the second gear rotates or not and controls the rotating direction.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a nasal laryngoscope which has the function of injecting and administering drugs and 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 i...

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
