Ear fiber endoscope for tympanic membrane puncture

Abstract

The invention relates to the technical field of tympanic membrane puncture, and discloses an ear fiber endoscope for tympanic membrane puncture, which comprises a handheld tube, the inner wall of the handheld tube is slidably connected with a combination tube, the right side of the combination tube is provided with a fixing hole, and the right side of the handheld tube is fixedly connected with two positioning springs; the right ends of the two positioning springs are fixedly connected with a same force application handle, and the left side of the force application handle is fixedly connected with a fixing rod located between the two positioning springs. The use length of the ear fiber endoscope can be effectively and rapidly adjusted through the fixing hole and the fixing rod, an adjusting screw rod is controlled to rotate through an operation ring, and the rotation of the adjusting screw rod enables a threaded plate to move up and down under the limiting of a limiting rod; and the length of the ear fiber endoscope is adjusted in a high-precision manner through thread transmission, so that the use length of the ear fiber endoscope is quickly adjusted in a high-precision manner.

Description

Technical field [0001] The present invention relates to the field of tympanic membrane puncture, and more particularly to a tympanic endoscope with a tympanic membrane puncture. Background technique [0002] The mass film position is inclined, each of which is 45 degrees and horizontal planes of the head, and the outer surface is forward, downward, outward position, and the baby's tympanic membrane is inclined, with a few horizontal positions, the outer layer of the tympanic membrane The external auditory canal skin continues, the inner layer and the tympanic mucosa, middle-clamping fiber tissue, relaxed portion fiber tissue, is the weak place of tympanic membrane, so it is often perforated here because of otitis media or trauma. [0003] With the rapid development of the tympanic membrane puncture, it also increases for tympanic membrane puncture facilities, but existing tympanic membrane puncture ear fibrous endoscopes is greatly affected by normal use efficiency and quality be...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the existing ear fiberscope for tympanic membrane puncture cannot adjust the length quickly and with high precision, which greatly affects the normal use efficiency and quality, and now Some ear fiberscopes for tympanic membrane puncture cannot adjust the angle between the observation structure and the hand-held structure very well, which greatly affects the normal observation range and observation efficiency.
