Description

Technical Field

[0001] The utility model relates to the technical field of medical clinical equipment, in particular to an auxiliary tooth pad for intraoperative electrophysiological monitoring. Background Art

[0002] During the intraoperative monitoring of motor evoked potentials, the patient may bite the tongue unconsciously due to the tonic contraction of the masseter muscle caused by transcranial electrical stimulation, and the upper and lower teeth may bite too hard, causing the teeth to break or fall out. Some patients may even bite the tracheal tube flat, thus affecting ventilation and causing serious consequences. Although intraoperative neuroelectrophysiological monitoring can improve the safety of surgical operations, it also brings about adverse events of oral-related injuries.

[0003] Patent publication number CN202311138673.9 discloses an intraoperative electrophysiological monitoring and Ebus intraoperative general anesthesia lower lip teeth and endoscope protection tooth pad, including two tooth pad bodies, the two tooth pad bodies are symmetrically arranged, the top of the tooth pad body is provided with an upper tooth alveolus, and the bottom of the tooth pad body is provided with a lower tooth alveolus, and two silicone positioning bands are provided on one side of the two tooth pad bodies close to one end of the cotton yarn ball, and one end of the two silicone positioning bands is respectively fixed to the top and bottom of this side of the tooth pad body. The device can prevent the patient from damaging the lips, tongue and teeth due to strong biting under electrical stimulation during the prone position and electrophysiological monitoring. However, the shallow alveolar groove of the tooth pad body cannot fix the position well, and the teeth can easily fall off the tooth pad body. Even if a silicone positioning belt is provided at the rear end of the tooth pad body, the positioning belt is only on one side of the end and cannot effectively prevent the front end of the tooth pad body from shifting. When the patient bites strongly and misaligns, the tooth pad body is still easy to fall off the teeth. In addition, the tooth pad body uses a cotton ball to absorb secretions. Generally, the human oral cavity has a lot of secretions. The cotton ball quickly absorbs the liquid and cannot be discharged, so its effect is minimal. Placing it in the mouth is likely to cause discomfort and hinder the placement of an endotracheal tube. Utility Model Content
