Problems solved by technology

The distance between the tympanic membrane and the opening of the external auditory canal is about 2.5cm-3.5cm. The external auditory canal is a long and narrow curved tube (the direction of the external auditory canal of adults is forward and downward, and the direction of the external auditory canal of children is forward and upward); the operation space is narrow and long, and the tympanocentesis is difficult. It is not easy for young doctors to master; due to fear, insufficient anesthesia before puncture, or pain stimulation during operation, patients often avoid the head unconsciously, resulting in difficulty in puncture positioning and complications

Abstract

The invention provides a tympanum puncture positioning device which comprises a guide hole, wherein more than one fixation bars radiated outwards are disposed with the guide hole as the center, and the fixation bars are disposed at a mutual interval. According to a human ear structure, the tympanum puncture positioning device provided by the invention is adaptively designed into an elliptic structure, and the whole positioning device is placed in a patient's ear by adopting a transparent silica gel material, so that discomfort of the patient is avoided, and a doctor can send a puncture needle and the positioning device into an external auditory canal under direct observation. According to a tympanic membrane quadrant, the guide hole is adaptively disposed on the lower half part of the center shaft of the positioning device, the guide hole can be aligned to a front lower quadrant of a tympanic membrane in the whole course through application of the fixation bars, and the puncture needle will not be penetrated too deeply into a tympanic cavity.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a tympanic membrane puncture positioning device. Background technique [0002] The tympanic membrane, also known as the eardrum, is an elastic gray-white translucent membrane that separates the external auditory canal from the middle ear. The tympanic membrane is about 2.5cm-3.5cm away from the opening of the external auditory canal, and is located between the external auditory canal and the tympanic cavity. The height of the tympanic membrane is about 9mm, the width is about 8mm, the average area is about 90 square millimeters, and the thickness is 0.1mm. Clinically, the tympanic membrane is often divided into four quadrants, that is, an imaginary straight line is drawn along the mantle of the malleus, and a straight line perpendicular to it is drawn through the umbilical cord of the tympanic membrane, and the tympanic membrane can be divided into four quadrants: antero-superi...
