Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a surgical auxiliary support device for otolaryngology head and neck surgery. Background Art

[0002] The surgical area of the throat, head and neck is adjacent to the airway. During the operation, the airway patency is easily affected by blood and secretions. Moreover, traditional tracheal intubation causes great damage to the airway and has many postoperative complications. There is an urgent need for a safer and more effective airway management method. As a supraglottic ventilation device, the laryngeal mask has significant advantages: the operation does not require a laryngoscope to deeply expose the glottis, has little irritation to the throat, and can reduce postoperative complications such as laryngeal edema and vocal cord injury; it can maintain the physiological function of the airway, ensure oxygenation and ventilation, and does not affect the operation space of the oral cavity and throat, meeting the special requirements of this type of operation for airway management.

[0003] When a laryngeal mask is inserted, gauze is usually used to pack and block the pharynx. However, during use, due to the surgical movements, the gauze is likely to be displaced, resulting in insufficient sealing around the laryngeal mask and unable to play a good sealing role. Moreover, due to the insufficient moisture and blood isolation of the gauze itself, secretions and blood are likely to accumulate in the surgical area. And because the device seals the esophagus and the gauze blocks the view, it is inconvenient to monitor gastric reflux. Therefore, we propose a surgical auxiliary support device for otolaryngology head and neck surgery. Summary of the Invention

[0004] The purpose of the present invention is to provide a surgical auxiliary support device for otolaryngology head and neck surgery to solve the problems of gauze displacement, resulting in insufficient sealing around the laryngeal mask and unable to play a good sealing role, insufficient moisture and blood isolation of the gauze itself, easy accumulation of secretions and blood in the surgical area, blocking of the view by the gauze, and inconvenience in monitoring gastric reflux as mentioned in the above background art.

The inflated balloon allows the gas inside to enter the inside of the telescopic rod through a connecting pipe and a second inflation pipe. The telescopic rod is stretched by the gas and pushes the moving ring to move on the surface of the support rod. The moving ring moves through a first connecting member, and the first connecting member pushes a fixed rod to rotate through a connecting rod and a second connecting member, so as to support the patient's cheek.

[0045] Embodiment 2

[0046] like Figures 1 to 2 In the second embodiment, other structures remain unchanged. What is different from the first embodiment is that a one-way valve (not shown in the figure) is fixedly connected to the middle of the connecting pipe 303. The connecting pipe 303 can fix the position of the one-way valve.

[0047] The following is a further introduction in combination with specific working methods. For details, see the following description: Specifically, when the surgical assistant support device for the throat, head and neck is working, the contact rod 8 is pushed, so that the support rod 5 moves inside the fixed rod 408. The limit tooth plate 9 restricts the position of the contact rod 8 to ensure that the contact rod 8 will not automatically retract inward. The flow path inside the three-way valve 205 is switched, so that the connecting pipe 206 is internally connected to the second inflatable pipe 404. The inflatable balloon 207 is pressed, and the gas inside the inflatable balloon 207 enters the telescopic rod 403 through the connecting pipe 206 and the second inflatable pipe 404. The telescopic rod 403 is stretched by the gas and pushes the moving ring 402 to move on the surface of the support rod 5. The moving ring 402 moves through the first connecting member 405. The first connecting member 405 pushes the fixed rod 408 to rotate through the connecting rod 406 and the second connecting member 407, so that the support leg 6 and the limiting plate 7 support the patient's cheek;

[0048] When the support leg 6 and the limiting plate 7 reach the appropriate positions, the flow path inside the three-way valve 205 is switched, so that the connecting pipe 206 is internally connected to the first inflatable pipe 204. The inflatable balloon 207 is squeezed, and the gas inside the inflatable balloon 207 enters the expansion balloon 202 through the connecting pipe 206 and the first inflatable pipe 204. The expansion balloon 202 expands due to the gas and blocks the patient's pharynx, so that the pharynx is sealed and only a smooth airway can be established between the main body 1 and the outside world, providing oxygen for the patient and performing effective gas exchange. The expansion of the expansion balloon 202 drives the sponge ring 203 to expand. The expansion of the sponge ring 203 can contact the pharynx, and the sponge ring 203 adsorbs the secretions and blood accumulated in the surgical area. When the expansion balloon 202 expands to the appropriate degree, the three-way valve 205 is switched so that the connecting pipe 206 does not communicate with the first inflatable pipe 204 and the second inflatable pipe 404;

[0049] When gastric acid reflux occurs, the gastric acid is blocked by the permeable membrane 302. Only hydrogen ions in the gastric acid pass through the permeable membrane 302 and enter the placement box 301. The hydrogen ions react with the sodium bicarbonate placed in the placement box 301 to generate carbon dioxide. The carbon dioxide enters the fixed pipe 304 through the connecting pipe 303 and pushes the piston 305 inside the fixed pipe 304 to move outward. The piston 305 pushes the telescopic ring 410 to move on one side of the support ring 401 through the fixed plate 306. The movement of the telescopic ring 410 pushes the fixed ring 201 to move, so that the expansion balloon 202 and the sponge ring 203 fixed on its outside enhance the contact force on the pharynx. And due to the movement of the telescopic ring 410, it is convenient for the doctor to monitor the degree of gastric acid reflux.
