The difference between the apparatus for compressing semilunar ganglion of trigeminal nerve of this embodiment and the apparatus for compressing semilunar ganglion of embodiment one, embodiment two and embodiment three lies in that the number of cavities in the supporting tube 30 is different, and the structure and composition of the components such as the sealing head 19 and the injector 22 in the apparatus are the same, and will not be described herein again.
Further, in the present embodiment, the support tube 30 has three cavities. However, it should be noted that in other embodiments, the number of the cavities may also be more than three, for example, in one embodiment, the support tube 30 may have four cavities, one of the four cavities is the fluid channel 31, one of the four cavities is the guide wire channel 33, the other two cavities are the guide wire channels 32, one of the two guide wire channels 32 is used for accommodating the first guide wire 16, and the other is used for accommodating the second guide wire 17, specifically, the number of the cavities of the support tube 30 may be set according to actual needs, and the above-mentioned embodiment is not limited in particular.
Specifically, the specific clinical operation of the operation using the above-mentioned trigeminal semilunar junction compression device is as follows:
firstly, a patient takes a supine position after general anesthesia, a cloth roll with a proper height is wrapped on a shoulder pad to ensure that the neck is slightly stretched, then, a channel is established at a position of about 2.5cm beside an affected side corner of the mouth by means of X-ray image positioning under the environment of X-ray, a first saccule 10 and a second saccule 11 are inserted, and after the first saccule 10 and the second saccule 11 enter the half-moon positioning of trigeminal nerve of a Meckle's cavity, an electrophysiological nerve signal monitoring device is used for measuring a nerve signal before treatment; then, injecting a diluted contrast medium into the inner support tube 34 through the liquid injection cavity 181 of the connecting piece 18 to inflate the first balloon 10 and the second balloon 11, wherein the amount of the injected diluted contrast medium can ensure that the Meckle's cavity is just filled, monitoring the inflated shapes of the first balloon 10 and the second balloon 11 laterally through an X-ray image, monitoring a nerve signal in the treatment process through an electrophysiological nerve signal monitoring device, continuously adjusting the shapes and positions of the first balloon 10 and the second balloon 11 in the process, keeping the first balloon 10 and the second balloon 11 inflated to press the trigeminal nerve meniscus for 3-7 minutes, and when a nerve signal difference value reaching the clinically optimal treatment effect appears, the operation is successful, at the moment, extracting the contrast medium, and ending the operation.
The half-moon-shaped trigeminal nerve compression device can be connected with the electrophysiological nerve signal monitoring device to monitor the magnitude of the pain sensation nerve signals of the trigeminal nerve of a patient before and during an operation, so that whether the expected pain disappearance effect is achieved by treatment or not can be judged through the difference of the nerve signals, the treatment effect can be quantitatively evaluated, the defect that the treatment effect is uneven due to the fact that no quantitative parameter is clinically used for evaluating the treatment standard is overcome, the clinical effects of accurate treatment, quick treatment, improvement of prognosis and reduction of complications can be achieved, the disease cure rate can be effectively improved, and the wide popularization and application of the half-moon-shaped trigeminal nerve balloon compression technology are facilitated.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
