Endotoscpe capable of continuous underwater operation

Abstract

The invention discloses an endoscope capable of continuous underwater operation. The endoscope comprises a shell, an imaging device used for stretching into the ear and shooting, an illuminating system used for providing illumination for a shooting area of the imaging device, and a cleaning system used for extending into the ear to clean the shooting area. The cleaning system, the imaging device and the illuminating system are arranged on the shell; the cleaning system is arranged on the imaging device so that the cleaning system and the imaging device can extend into the ear at the same time;the illuminating system is connected to the imaging device; and the imaging device can shoot the condition in the ear and generate an image. Because there is no light in the ear, the illuminating system needs to provide lighting, and the cleaning system and the imaging device are simultaneously inserted into the ear; when the area shot by the imaging device is bleeding or sclerotin needs to be cleaned, the area shot by the imaging device can be continuously perfused and circularly flushed by connecting an external water source with the cleaning system, so that the visual field can be kept clear all the time; other auxiliary devices are not needed and surgical operation does not need to be interrupted, thus improving the surgical efficiency.

Description

technical field [0001] The invention relates to the technical field of otoscopes, and more specifically relates to a sustainable underwater operation otoscope. Background technique [0002] Otoendoscope is a kind of endoscope used to check the eardrum, tympanic cavity (when the tympanic membrane is perforated), the diagnosis of middle ear and external auditory canal diseases, and can perform surgical imaging of the middle ear and lateral skull base. Otoendoscopy can observe parts that are difficult to observe with a surgical microscope, such as the upper tympanic cavity and posterior tympanic cavity, so that middle ear lesions can be detected in time and the recurrence rate of lesions can be reduced. The general ear endoscope is composed of an optical imaging system and a lighting system. When used with a camera system and a cold light source, medical staff can observe the lesions in the patient's ear through a high-definition display. [0003] The prior art has the followi...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following problems: Since the operator holds the mirror in one hand and operates with one hand in the other hand, in order to stop the bleeding and keep the operative field clear during the operation, it is necessary to interrupt the operation to stop the bleeding, which is time-consuming and laborious

In order to cooperate with the removal of part of the bone during the operation, an assistant is required to assist in continuous flushing and suction. It is difficult to ensure the consistency of the flushing direction and visual field, and it will also reduce the efficiency of the operation.
