Auxiliary head fixing device for bronchial cannula

Abstract

Provided is an auxiliary head fixing device for a bronchial cannula. By adopting the auxiliary head fixing device for the bronchial cannula, it can be convenient to fix and adjust the head of a patient subjected to a bronchoscope operation, and accordingly the efficiency and quality of the operation are improved. According to the technical scheme, the auxiliary head fixing device includes a bed board, a support plate is arranged on the lower portion of the bed board, two clamp plates are arranged at the upper end of the bed board, an arc sleeve is mounted on the bed board, a spline is connected to the lower end of the arc sleeve, a rotation shaft is arranged under a through groove, gears meshing with the spline are arranged on the rotation shaft, rotation of the rotation shaft can drive the arc sleeve to move up and down through meshing of the gears and the spline, a rotation disc is connected to the rear clamp plate, a shaft sleeve is arranged at the center of the rotation disc, a limit disc is fixedly connected to the front clamp plate, location holes are formed in the end face of the rotation disc, and location rods are arranged on the end face, opposite to the rotation disc, ofthe limit disc. When the auxiliary head fixing device is in an original state, the location rods are inserted in the location holes so that the rotation shaft cannot rotate, and when the clamp platesslide in reverse directions, the location rods can be separated from the location holes; the auxiliary head fixing device is novel in design and is provided with a smartly designed structure.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary devices, in particular to a head auxiliary fixing device for bronchial intubation. Background technique [0002] Rigid bronchoscopy is a highly skilled technique that combines airway visualization, therapeutic manipulation, and patient ventilation. Its value lies in its use as an interventional channel to allow flexible bronchoscopes and other surgical instruments to enter the airway , perform operations such as stent release, foreign body removal, freezing, electrocution, and laser ablation under direct vision, and can protect the upper airway structures such as the glottis. It has unique advantages in taking out various stents. [0003] In recent years, respiratory doctors in my country have gradually realized the importance of rigid bronchoscopy. Major respiratory endoscopy centers are competing to introduce rigid bronchoscopy equipment and learn rigid bronchoscopy technology. The pl...

Problems solved by technology

At present, there is no special rigid bronchoscope position assisting device. Using methods such as pillow shoulder pads and head rings, it is easy to shift during operation and cause damage to the glottis and vocal cords of the patient's mouth, and the incidence of complications is high. In view of the above situation, in order to overcome the existing Technical defect, the purpose of the patent of this invention is to provide a posture assisting device for rigid bronchoscope insertion, which can effectively solve the success rate of rigid bronchoscope insertion, shorten the insertion time, and reduce the incidence of complications caused by it. Design of a head auxiliary fixation device for bronchial intubation of the present invention
