Vocal cord polyp exsector

Abstract

The invention provides a vocal cord polyp exsector which comprises a pump component, a water scalpel component, a blocking catheter component, a laryngoscope component and an optical fiber object lens. The water scalpel component is connected with the pump component, the blocking catheter component wraps the water scalpel component and positioned on one side of the pump component, the laryngoscopecomponent is connected with the blocking catheter component and wraps the water scalpel component, and the optical fiber object lens is arranged to the blocking catheter component, corresponds to thewater scalpel component and is connected with the laryngoscope component. The vocal cord polyp exsector is of a split structure, and the pump component, the laryngoscope component and the optical fiber object lens can be disinfected for reuse, so that economic burden of patients is lowered; the water scalpel component and the blocking catheter component are disposable articles, so that secondarycross infection is eliminated; doctors and observers watch images of vocal cords of the patients in real time through an outside workstation, so that safety of vocal cord polypectomy.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a vocal cord polypectomy device. Background technique [0002] Vocal cord polyps are benign hyperplastic lesions that occur in the superficial layer of the vocal cord lamina propria, and are also a special type of chronic laryngitis. Vocal cord polyps mainly manifest as hoarseness, and the degree of hoarseness varies with the size and location of the polyps. Vocal cord polyps occur in the gray-white, smooth-surfaced polypoid tissue at the front-middle edge of one side of the vocal cord, mostly single or multiple on one side, pedunculated or broad-based, often gray-white translucent, or small red protrusions, with The pedicle often moves up and down with the breath, and the big one can block the glottis and cause dyspnea, which affects normal pronunciation. Surgical resection is the main method for the treatment of vocal cord polyps. Indirect laryngoscopy surgery is ...

AI Technical Summary

Problems solved by technology

Fiberoptic laryngoscope or electronic laryngoscope for vocal cord polypectomy is suitable for pedunculated polyps, but it is difficult to completely remove wide-based vocal cord polyps

Laryngoscope vocal cord surgery under a microscope has the advantages of clear vision and high precision. However, for patients with obesity, short neck, cervical spondylosis, stiff neck, and high laryngeal body, it is often impossible to directly see the lesion under the microscope and the operation is terminated.
