Problems solved by technology

However, it is necessary to pull out the laryngeal mask when positioning the functional area, and then insert the laryngeal mask after positioning. There are certain risks and difficulties for the patient, and it also increases the complexity of the surgeon's operation, and postoperative complications may occur

Embodiment Construction

[0023] The catheter device for wake-up anesthesia in brain functional area surgery of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] refer to figure 1 , figure 2 and image 3 , the present invention is used for the catheter device of brain functional region operation wake-up anesthesia, comprises a tracheal catheter 10, an esophageal catheter 40 that is arranged side by side with this tracheal catheter 10, and the part of esophageal catheter 40 and tracheal catheter 10 is inserted in their oral cavity is integrated Shaped, and the outer ends of the parts that protrude from the oral cavity are bifurcated to separate the respective openings 41, 11 from each other. closed. The esophageal catheter 40 and the endotracheal catheter 10 are provided with an esophageal sealing cuff 20 near the tops 41 and 11 of their inner ends, and the esophageal catheter 40 and the endotracheal catheter 10 are also provided with a p...

Abstract

The invention relates to a catheter device and a method thereof for waking up the anesthesia in a brain functional region surgery, comprising a tracheal catheter, an opening is formed on the top of the outer end of the tracheal catheter which is inserted to the esophagus direction, the top part of the inner end is closed, an esophagus closed cuff is arranged in the vicinity of the top part of theinner end, a pharyngeal cavity closed cuff is further arranged on the tracheal catheter; a vent hole is arranged at the part of the tracheal catheter between the esophagus closed cuff and the pharyngeal cavity closed cuff for leading an air duct to be communicated with and a glottis of a trachea; the esophagus closed cuff and the pharyngeal cavity closed cuff are respectively connected with a ventpipe. The catheter device is provided with the esophagus closed cuff and the pharyngeal cavity closed cuff on the tracheal catheter and is provided with the vent hole between the esophagus closed cuff and the pharyngeal cavity closed cuff, so the usage of the catheter device of the invention for carrying out the waking-up of the anesthesia can not only meet the requirements on the precise positioning of the function region, but can also be safe and convenient, and the catheter does not need to be inserted and drawn repeatedly, thus eliminating the risks of excessive injuries of a patient, being able to resect a tumor to the maximum extent and protecting the normal brain tissues of the brain functional region to the utmost extent.

Description

technical field [0001] The invention relates to a medical operation instrument for brain function area operation, in particular to a catheter device used for brain function area operation to wake up anesthesia. Background technique [0002] During surgery involving brain functional areas, neuronavigation and neuroelectrophysiological techniques are used for functional anatomical positioning, and patients are required to be awake to cooperate with the surgery. Therefore, the doctor wakes up the patient during the operation, and the language area surgery even requires the patient to be able to pronounce after waking up. In order to accurately locate the brain functional area (especially the language area), the current wake-up anesthesia methods mainly include local anesthesia and laryngeal mask insertion anesthesia. [0003] When simple local anesthesia is used, the patient can remain awake during the operation and cooperate with the operation, but due to the high incidence of...
