Problems solved by technology

Under the traditional otoscope technology, some operations cannot be directly realized, such as direct vision and operation in the upper tympanic cavity. At this time, it is necessary to grind the posterior upper wall of the enlarged external auditory canal, which not only increases the trauma but also increases the damage to blood vessels or nerves. other important structural risks
[0004] Therefore, the prior art still lacks a kind of ear endoscopic surgical device with high safety performance and convenient operation.

Embodiment Construction

[0021] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0022] like figure 1 As shown, in one embodiment of the present invention, the ear endoscopic surgical device includes a slender insertion rod 1, an imaging channel 2, a working channel 3, an operating mechanism 4 and a hand-held part 5, wherein the insertion rod 1 includes a hard rod body 11 and The probe part 12 located at the front end of the rod body, the outer diameter of the rod body 11 is smaller than the inner diameter of the ear canal, and is made of medical stainless steel. The probe part 12 can be bent in different directions under the control of the operating mechanism 4 . In order to adapt to the structural characteristics of the ear, that is, the ear canal is narrow and the tympanic cavity is relatively large, the len...

Abstract

The invention discloses an ear endoscope device. The device comprises a slender insertion rod, an imaging pipeline, a working channel and an operating mechanism, the insertion rod comprises a rod bodyand a probe located at the front end of the rod body, and in the operation process, an operator can control the probe part to bend through the operating mechanism, observe different areas in the earand insert a surgical instrument through the working channel for surgical operation. The arrangement of the probe part of the ear endoscope device conforms to the structural characteristics in the ear, observation and surgery can be carried out at the same time through one-hand operation, the safety performance is high, and operation is convenient and fast.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a multifunctional ear endoscopic operation device. Background technique [0002] In recent years, minimally invasive ear endoscopic surgery has been widely used in functional surgery of the outer ear and middle ear. At present, there are two types of optical fiber beams in the otoscope, the guide beam and the image beam, which are used for illumination and imaging respectively. Different from the wide and straight external auditory canal structure of Caucasians in western countries, the external auditory canal of Chinese population is relatively curved, which limits the maximum field of view of rigid otoscope to a certain extent. It is necessary to replace the lens with different angles to meet the observation of different surgical areas, which causes inconvenience. Moreover, the current otoscope system can only provide lighting and imaging functions, and lacks a working chan...
