Adjustable direct laryngoscope

Abstract

The invention relates to an adjustable direct laryngoscope, which solves the problem that the existing laryngoscope is not reasonable in design and cannot enable focus portions such as vocal cords and anterior commissure to be sufficiently exposed. The adjustable direct laryngoscope is characterized by comprising a handle, a worm, a worm gear seat fixed on the handle, a worm gear provided with an adjusting screw hole, an adjusting screw rod installed in the adjusting screw hole, a movable mirror sheath seat provided with a sphere head installation groove, a fixing mirror sheath support, a fixed mirror sheath and a movable mirror sheath fixed on the movable mirror sheath seat. A worm gear groove and a worm installation hole are arranged in the worm gear seat, the movable mirror sheath seat is connected onto the worm gear seat, the movable mirror sheath is located between the fixed mirror sheath and the handle, the worm gear is installed in the worm gear groove of the worm gear seat, a guiding structure is arranged between the adjusting screw rod and the worm gear seat, a sphere head is arranged at the front end of the adjusting screw rod and installed in a sphere head mounting groove, and the worm is installed in and meshed with the worm installation hole. The adjustable direct laryngoscope is reasonable in structural design, and can enable portions such as the vocal cords and the anterior commissure which are difficult to be exposed of patients having the laryngeal disease to be conveniently, fast and sufficiently exposed.

Description

technical field [0001] The invention relates to a laryngoscope, in particular to an adjustable direct laryngoscope, which is mainly used for treating human laryngeal diseases and belongs to the field of medical operation instruments. Background technique [0002] In the treatment of laryngeal diseases in the medical field, due to the particularity of the physiological position of the human larynx, it is a relatively difficult project to carry out minimally invasive laryngeal surgery in the course of clinical treatment and surgery. [0003] The trumpet-shaped tubular support laryngoscopes used in clinical treatment are usually early-designed instruments. The laryngoscope consists of a handle and a trumpet-shaped tubular instrument channel. The instruments used in the operation pass through the trumpet-shaped tubular instrument channel to reach the patient. throat. In the process of laryngeal surgical treatment using this type of instrument, there are problems such as narrow ...

AI Technical Summary

Problems solved by technology

The structure of the visual laryngoscope is relatively complicated, the function is relatively single, and the application area is narrow. It can only observe and diagnose the patient's larynx, and cannot perform other operations. The hospital also needs to be equipped with laryngoscopes with other functions. The input cost of equipment also brings inconvenience to laryngeal surgery

[0005] To sum up, there is currently no laryngoscope with reasonable structural design, convenient use, simple operation, which can conveniently, quickly and fully expose the vocal cords, anterior commissure and other difficult-to-expose lesions of patients with laryngeal diseases.
