A kind of trachea measuring device and measuring method

Abstract

A trachea measuring device and a trachea measuring method relate to the technical field of medical appliances. The trachea measuring device comprises an operating handle (1), a pull ring (2), an outer sleeve (3), an equilateral triangular fixed assembly, a drawing guide wire (7), and a pair of measuring guide wires (6). The operating handle (1) is I-shaped, and the operating handle (1) is internally provided with a through hole A (1-1) for the drawing guide wire to pass through. The outer sleeve (3) is internally provided with a through hole B (3-1) for the drawing guide wire to pass through. The equilateral triangular fixed assembly comprises a branching clamp plate (4) and a pair of branching rings (5). The branching clamp plate (4) is provided with a threading hole (4-1) in the center, and is fixedly mounted inside the end near the outer sleeve (3). Through the device and the method, the diameter of a trachea can be measured directly under operation of a fiber bronchoscope. The method is time-saving. The device is of low manufacturing cost. Accurate data can be provided for placement of an airway stent. The device and the method have very good application and popularization values.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a trachea measurement device and a measurement method. Background technique [0002] At present, most methods of measuring tracheal diameter rely on CT results to calculate the value. However, due to the influence of CT resolution and slice thickness, as well as the different values ​​of tracheal images taken when patients exhale or inhale, the measurement of tracheal diameter brings Errors, time-consuming and expensive. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to mainly provide a trachea measurement device and measurement method in order to solve the above technical problems. [0004] The trachea measurement device of the present invention comprises an operating handle, a pull ring, an outer sleeve, an equilateral triangle fixing component, a pulling wire guide wire and a pair of measuring guide wires. The A through hole of the wir...
