Irregular hard tracheoscope

Abstract

The invention discloses an irregular hard tracheoscope. The irregular hard tracheoscope comprises a lens body of a tubular structure, wherein the lens body is partially bent, an eyepiece end of the lens body is connected with a display, an objective end of the lens body is provided with a lens, and a transmission line for connecting the display and the lens is arranged in the lens body. The objective end of the lens body is of an oblique tangent plane, a flexible curved plane of the objective end of the lens body is longer than a back curved plane of the objective end of the lens body, the lens is mounted in the objective end of the lens body at the back curved plane, and the flexure of the objective end of the lens body is improved in shape and is in better fit with dissected radian of anupper respiratory tract, so that the objective end can be more easily placed and adjusted to a supraglottic region of a pharyngeal part, an jacketed tracheal catheter can be excellently fixed and thus is not prone to slippage; and after the objective end of the lens body is placed in an oronasal chamber, an internal included angle formed by an inserted part of the lens body in the upper respiratory tract is not greater than 90 degrees, dissected angles of an oropharynx axis and a trachea glottal axis can be in better fit, a head posture is not required to be specially adjusted, the shape is in better fit with natural dissected radian, and the inserting to a target position is facilitated.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a special-shaped rigid bronchoscope. Background technique [0002] Rigid bronchoscope (rigid visual bronchoscope) as an inspection and treatment tool provides a safe and effective method for clinical observation of the glottis and trachea. Experienced operators use fiberoptic bronchoscope and rigid bronchoscope, which can be used in Complete the inspection operation in the patient's natural position; [0003] The rigid bronchoscope currently used clinically is represented by Sekoni, which has the same structural characteristics, and the main defects are: [0004] 1. The lens axis of the objective lens is coaxial with the tangent extension line of the lens lumen, and the lens and the end of the lens body are on the same plane, which is easily covered by soft tissue; [0005] 2. The curvature of the lens body at the eyepiece end and the objective lens end is too small, and the ...

Problems solved by technology

[0010] The technical problem to be solved by the present invention is that the existing rigid bronchoscope is easily blocked, resulting in difficulty in imaging, and its shape cannot completely match the anatomical radian of the upper airway. The electro...
