Throat endoscopic surgery device

Abstract

The invention discloses a throat endoscopic surgery device. The throat endoscopic surgery device comprises a conveying rod and an operating mechanism. The conveying rod comprises a rigid part and a flexible part, the flexible part is provided with at least one joint, and the joints can be bent under control of the operating mechanism. The operating mechanism is arranged at the rear end of the conveying rod or the rigid part of the conveying rod, and an imaging channel and working channels are formed in the conveying rod and penetrate through the conveying rod. The device further comprises a linkage part. The device is provided with an arc-shaped structure, and the throat cavity can be fully exposed without extreme head hypsokinesis, so that an imaging part and surgical instruments smoothlyenter the throat part. By means of the bendable conveying rod, damage to the normal structure and the mucosa of the throat in the operating process can be reduced, the view range of an endoscope is widened, and dead zones are eliminated. The linkage part can be connected with a mouth prop, a direct laryngoscope lens and a trachea cannula groove, so that the device is convenient to use and fix. The functions of the endoscope are enriched through the multiple endoscope working channels. The endoscope can be held with a single hand, so that the operation is more stable and more precise.

Description

technical field [0001] The invention relates to a throat endoscopic surgery device, in particular to a throat endoscopic surgery device. Background technique [0002] Laryngoscope is an important diagnostic and therapeutic tool in otolaryngology. Due to the appearance of supporting laryngoscope and microscope, minimally invasive laryngeal surgery under supporting laryngoscope has been widely used in various benign and malignant lesions of the throat. Traditional support laryngoscope surgery requires general anesthesia and requires high positioning of the patient. It requires the surgeon's eyes, incisors, and lesion to be in a straight line, that is, the patient needs to tilt his head back to form a straight line before proceeding. surgery (eg figure 1 As shown), head tilting back severely will cause great harm to the patient. For patients with cervical lesions or short mandibles, the head cannot be tilted back. In advanced age, poor general condition, micrognathia, thoracic...

Problems solved by technology

Traditional support laryngoscope surgery requires general anesthesia and requires high positioning of the patient. It requires the surgeon's eyes, incisors, and lesion to be in a straight line, that is, the patient needs to tilt his head back to form a straight line before proceeding. surgery (eg figure 1 As shown), head tilting back severely will cause great harm to the patient. For patients with cervical lesions or short mandibles, the head cannot be tilted back. In advanced age, poor general condition, micrognathia, thoracic spine deformity, and short neck There is a certain degree of limitation in the application of special patients such as tongue hypertrophy; and after the endoscope enters the oral cavity, it will touch the teeth, wear the teeth, easily damage the incisors, and have adverse consequences of loosening; further supporting the tubular lighting of the laryngoscope The scope is narrow, and the space of the throat is large and irregular, and there are many depressions and gully-like structures, resulting in blind spots in the field of vision; Easy to collide, causing inconvenience in operation
