Abstract

The invention provides an improved mouth gag for exposing a tongue root. The improved mouth gag comprises a handle and a tongue depressor, wherein the handle is provided with a mounting part and a connecting hole, a clamping buckle is arranged in the connecting hole, the tongue depressor is provided with a connecting part, a tongue root part and an arc part, a clamping groove is formed in the connecting part, and the connecting part of the tongue depressor passes through the connecting hole of the handle, and is in clamping connection with the clamping buckle through the clamping groove. According to the invention, the tongue root part with a curve and the tongue depressor with the arc part are arranged to realize the forward movement of the tongue root while a tongue body is pressed down, so as to greatly increase the exposure volume of the tongue root and the surgical operation space; meanwhile, the connection mode of the clamping buckle and the clamping groove is set, so that the improved mouth gag is convenient to assemble and disassemble, and two tongue depressors are provided for replacement to adapt to different tongue root illnesses.

Description

technical field [0001] The invention relates to a gag, in particular to an improved gag for exposing the base of the tongue. Background technique [0002] Common clinical diseases involving the base of the tongue include: dysphagia, dyspnea, speech disorder, obstructive sleep apnea syndrome, etc. caused by tongue base hypertrophy, tongue (root) tonsil hypertrophy, tongue base lymphoid tissue hyperplasia, etc.; tongue base benign tumor; Valley, epiglottis benign lingual surface swelling. Existing gags such as David's gag are often used in soft palate, palatine tonsil and posterior pharyngeal wall operations. The tongue depressor attached to the gag presses the tongue, causing the base of the tongue to press against the posterior pharyngeal wall, affecting the surgical field of view of the base of the tongue. Due to the pressure on the tongue body, the base of the tongue is squeezed backward, and the operation space of the base of the tongue and throat is obviously limited. ...
