Auxiliary positioning device for clinical operation of otolaryngology department

Abstract

The invention provides an auxiliary positioning device for clinical operation of the otolaryngology department, which solves the problem of opening the mouth of a patient in the operation process, plays a positioning role for the tongue of the patient, prevents liquid from entering the trachea and the esophagus of the patient during flushing, and is easy, convenient and flexible to operate, wide in applicability and convenient to popularize. According to the technical scheme, the auxiliary positioning device comprises a head supporting piece and is characterized in that the head supporting piece is transversely connected with the oral cavity supporting device in a sliding mode, the oral cavity supporting device comprises a supporting frame which transversely slides, is rotationally connected to the head supporting piece and can ascend and descend, the supporting frame is transversely connected with a left distraction piece and a right distraction piece in a sliding mode, the front ends and the rear ends of the left distraction piece and the right distraction piece are rotationally connected with threaded rods respectively, the right ends of the threaded rods are in threaded connection with the right distraction piece respectively, the right ends of the two threaded rods are connected through a connecting belt and rotationally connected with a supporting piece, and the distance between the supporting piece and the right end face of the supporting frame is adjusted through a screw.

Description

technical field [0001] The invention relates to a medical device, in particular to an auxiliary positioning device for ENT clinical operation. Background technique [0002] Ear, nose and throat diseases are frequent diseases of adolescents. During the process of physical development, adenoid diseases caused by factors such as improper diet, obesity or dysplasia increase year by year. Adenoids are also called pharyngeal tonsils or proliferative bodies, located at the top of the nasopharynx With the posterior pharyngeal wall, it belongs to the lymphatic tissue, and the surface is like orange petals. Adenoids, like tonsils, grow gradually with age after birth, proliferate vigorously at the age of 2-6, and gradually shrink after the age of 10. Adenoid hypertrophy is the pathological hyperplasia of adenoids due to repeated stimulation of inflammation, which causes symptoms of nasal congestion and mouth breathing, especially aggravated at night, with sleep snoring and disturbed s...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an auxiliary positioning device for otolaryngology clinical surgery, which solves the problem of opening the patient's mouth during the operation, and at the same time positions the patient's tongue. function, and at the same time prevent liquid from entering the patient's trachea and esophagus during flushing, and at the same time, it is easy and flexible to operate and has wide applicability. The technical solution is to include a head support, which is characterized in that the head support The upper side is slidably connected with an oral cavity support device, and the oral cavity support device includes a support frame that is horizontally slid and rotatably connected to the head support and can be raised and lowered. The support frame is horizontally slidably connected with a left expansion piece and a right expansion piece. The front and rear ends of the left expansion piece and the right expansion piece are respectively connected with threaded rods. The right ends of each threaded rod are respectively threaded with the right expansion piece. There is a support piece, and the distance between the support piece and the right end of the support frame is adjusted by screws
