Tongue root draw hook

Abstract

The invention provides a tongue root draw hook which comprises a hook body, wherein a fork body is arranged at the front end of the hook body, a telescopic connecting rod is arranged in the middle of the hook body, and an incisor baffle is arranged at the rear end of the hook body and is connected with a depth adjuster. The tongue root draw hook is simple and novel in overall structure, soft tissue including a tongue body is drawn towards the incisor integrally by exerting force on the tongue root through the fork body of the hook body, and the force exertion direction is almost perpendicular to the incisor. According to the tongue root draw hook, the exposed space of the pharyngeal cavity is improved greatly, mask ventilation can be conducted better, devices such as a laryngeal mask and a fiber bronchoscope can be placed in smoothly by enlarging space, and then ventilation or tracheal intubation can be conducted.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a tongue base retractor. Background technique [0002] At present, difficult airway, especially difficult mask ventilation, is a possible fatal risk during anesthesia induction, and it is also a problem that every anesthesiologist worries about. Once this situation arises and cannot be dealt with effectively, it will bring disastrous consequences to patients and medical workers. Therefore, solving difficult ventilation is also a topic of constant exploration in the anesthesia field. Although the laryngeal mask, video laryngoscope, fiberoptic bronchoscope and other equipment currently on the market have solved many difficult airways, some special patients with hypertrophy of the tongue, difficulty in mandibular support, sleep apnea syndrome, etc. If the cavity space is narrow and there is no space for equipment such as fiberoptic bronchoscope, it will not be possible to perform or...

Problems solved by technology

Although the laryngeal mask, video laryngoscope, fiberoptic bronchoscope and other equipment currently on the market have solved many difficult airways, some special patients with hypertrophy of the tongue, difficulty in mandibular support, sleep apnea syndrome, etc. If the cavity space is narrow and there is no room for equipment such as fiberoptic bronchoscope, it will not be possible to perform or improve mask ventilation, resulting in hypoventilation, hypoxia, carbon dioxide accumulation and even cardiac arrest
