Tracheal bronchus inner-diameter measuring ruler

Abstract

The invention discloses a tracheal bronchus inner-diameter measuring ruler which comprises a handle sleeve, a first straight pipe, a strip-type groove, a sliding sleeve, a wire spool, a connecting block, a hose, a spring, a rotating strip, a first guide wire, a second straight pipe, a limit sleeve, a fixed frame, a fixed plate, a second guide wire, a through hole, a clamping block, a scale grooveand a rubber sleeve. The measuring ruler is reasonable in structure and novel in design, the opening distance of a near-end jaw can be calculated through the telescopic length of the first guide wire,so that the inner diameter of tracheal bronchus can be measured, accurate data are acquired, data of the narrow tracheal bronchus in different directions on the same horizontal plane can be acquired,the hose can be wound on the surface of the wire spool through the wire spool and a clamping block on the handle sleeve, and the tail end of the hose can be fixedly limited by the clamping block, sothat the whole measuring ruler is conveniently carried and stored and worthy of popularization and use.

Description

technical field [0001] The invention relates to a tracheal inner diameter measuring ruler, in particular to a tracheobronchial inner diameter measuring ruler, which belongs to the technical field of medical instruments. Background technique [0002] The trachea and bronchi cause large airway stenosis due to benign and malignant lesions. At this time, it is necessary to understand the degree of airway stenosis on respiratory function damage and to evaluate the next step of tracheal treatment, such as before and after dilation, and stent implantation. [0003] At present, there may be a lack of tools for accurately measuring the inner diameter of the airway. When measuring the inner diameter of the tracheobronchi, bending tools such as curettes are generally used for estimation. Because the length of the bending head of such tools is fixed, the measurement error is often large, and it may not be possible. Obtain precise data on airway stenosis. Therefore, a kind of tracheobro...
