Technical Field

[0001] The utility model relates to a comprehensive endoscope lens which is suitable for ear, nose and throat examinations and belongs to the technical field of medical equipment. Background Art

[0002] Laryngoscope, nasal endoscope and otoscope are important tools used in clinical otolaryngology to check whether the corresponding organs of patients have lesions. Laryngoscope is used to check inflammation, cysts and other diseases in the throat; nasal endoscope is used to check nasal diseases such as rhinitis, sinusitis and nasal polyps; and otoscope is used to check lesions in the external auditory canal, tympanic membrane and middle ear. In order to observe the deep structures of the ear, nose and throat, instrument manufacturers have manufactured endoscopic lenses with different lengths, thicknesses and mirror inclinations according to the anatomical characteristics of the ear, nose and throat. This subdivision method enables different professional equipment to target different organs, and when used, it is more in line with the anatomical characteristics of different organs of the human body; but this subdivision method is not conducive to emergency and simple diagnostic processes; when patients need to check the ears, nose and throat at the same time, they need to replace different instruments, and even need to go to a special endoscopy room for examination by different doctors, which increases the diagnosis and treatment time; this subdivision method also adds more costs to the hospital for purchase, disinfection, use and storage; in order to adapt to a variety of endoscopy lenses, hospitals also need to set up special endoscopy rooms. Therefore, the technical field is in urgent need of an endoscopic lens with a length between different endoscopic lenses, moderate thickness, and a bevel, which can simultaneously examine the ears, nose, and throat to simplify the outpatient examination process of the otolaryngology department; this lens can be used directly on the treatment table of the treating physician, so that one patient has one endoscope, which not only reduces costs but also ensures the treating physician's continuous diagnostic and treatment thinking, obtains satisfactory comprehensive otolaryngology examination results, and improves the level of diagnosis and treatment. Utility Model Content

[0005] Preferably, the length of the straight tube is 11 cm.

[0006] Preferably, the outer diameter of the straight tube is 3.4 mm.

[0007] Preferably, the mirror surface forms an angle of 40 degrees with a plane perpendicular to the central axis of the straight tube.

[0008] Preferably, the handheld operation section of the mirror body is provided with a video interface and a light source interface.

[0009] Preferably, the light source interface is configured as a spiral interface.

[0010] Preferably, the video interface is configured as a snap-on interface.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] According to the characteristics of the human anatomy of most Chinese people and combined with the inventor's many years of clinical practice experience in otolaryngology, the utility model provides an endoscopic lens with a length between the different endoscopic lenses of the prior art, a moderate thickness, and a bevel; the utility model can simultaneously examine the ear, nose, and throat, simplifying the examination process of the otolaryngology clinic. It can be directly used on the treatment table of the diagnosing physician, so that one patient has one lens, which can not only reduce the diagnosis and treatment costs, but also obtain satisfactory otolaryngology examination results, and improve the diagnosis and treatment level of the otolaryngology department.

[0015] In order to make the present invention more clearly understood, a preferred embodiment is described in detail with reference to the accompanying drawings as follows:

[0016] like Figure 1 As shown, the utility model provides a comprehensive endoscope lens suitable for ear, nose and throat examination, including a scope insertion section 1 located at the front section and a scope handheld operation section 2 located at the rear section; the scope insertion section 1 includes a slender straight tube 3, the length of the straight tube 3 is 10-12 cm, and the outer diameter of the straight tube 3 is 3.0-3.5 mm; a mirror surface 4 is arranged at one end of the straight tube 3 away from the operator, and the mirror surface 4 is arranged at an angle of 35-50 degrees with a plane perpendicular to the central axis of the straight tube 3.

[0017] Preferably, the length of the straight tube 3 is 11 cm; the outer diameter of the straight tube 3 is 3.4 mm; and the mirror surface 4 is arranged at an angle of 40 degrees with a plane perpendicular to the central axis of the straight tube 3 .

[0018] The mirror body handheld operation section 2 is provided with a video interface 5 and a light source interface 6. The light source interface 6 is configured as a spiral interface; the video interface 5 is configured as a snap-on interface.

[0019] Example

[0020] like Figure 1 As shown, the utility model provides a comprehensive endoscope lens suitable for ear, nose and throat examination, comprising a scope insertion section 1 located at the front section and a scope handheld operation section 2 located at the rear section;

[0021] The insertion section of the scope includes a slender straight tube 3 for inserting into the human body to observe the internal structure of the organ. The length of the straight tube 3 is 11 cm; the outer diameter of the straight tube 3 is 3.4 mm; a mirror 4 is provided at the end of the straight tube 3 away from the operator, and the angle between the mirror 4 and the plane perpendicular to the central axis of the straight tube 3 is 40 degrees.

[0022] The mirror body handheld operation section 2 is provided with a video interface 5 and a light source interface 6. The light source interface 6 is provided as a spiral interface; the video interface 5 is provided as a snap-on interface.

[0023] Use of this utility model:

[0024] The lens (i.e., the straight tube 3) provided by the utility model is 11 cm long and can reach the nasopharynx through the inferior nasal passage of about 7-8 cm in length; the outer diameter of the lens (straight tube 3) is 3.4 mm, so that the lens (straight tube 3) can be observed and operated unhindered even in the relatively narrow space of the ear canal;

[0025] The mirror surface 4 has an angle of 40 degrees with the vertical direction (the plane direction perpendicular to the central axis of the straight tube 3), and the mirror surface 4 is inclined upward. The inclined mirror can be used to observe the structure of the vertical surface that is not on the mirror entry route.

[0026] The rear end of the lens (straight tube 3) is provided with an interface consistent with the existing general lens and lighting interface so as to be applicable to the display and lighting system of the existing endoscope.

[0027] When in use, the method of using the utility model in the nasal cavity and the external auditory canal is the same as the method of using the existing endoscope, except that it is necessary to adapt to the characteristics of the bevel mirror. When inserting the mirror, focus on the tip of the lens and use the local image of the tip as a reference for the direction of advancement. Practice makes perfect, and when necessary, the direction of the lens can be slightly rotated to align with the intended observation area.

[0028] When inspecting the larynx, the lens of the present invention needs to be turned over, and the inclined surface of the lens (mirror surface 4) extends downward into the posterior tongue area, so that the deep structure of the larynx can be observed.

[0029] Based on the human anatomical structure characteristics of most Chinese people and combined with the inventor's many years of clinical practice experience in otolaryngology, the utility model provides a comprehensive endoscope lens that is suitable for ear, nose and throat examinations, which simplifies the examination process of otolaryngology clinics. It can reduce the cost of diagnosis and treatment, obtain satisfactory otolaryngology examination results, and improve the diagnosis and treatment level of otolaryngology.
