AI Technical Summary

Technical Problem

In existing technologies, devices for determining the decompression effect of trigeminal neuralgia have limitations such as the inflexible adjustment of the probe spacing, difficulty in simultaneously detecting the overall signal of the nerve segment and accurately locating the local compression point, incomplete signal acquisition, inaccurate compression point location, cumbersome operation, and inability to provide real-time feedback, which affects the reliability of the decompression effect and the safety of the surgery.

Method used

The system employs a combination of forceps and a distance adjustment mechanism with an auxiliary central positioning mechanism. The distance adjustment mechanism allows for flexible adjustment of the acquisition probe spacing, while the auxiliary central positioning mechanism utilizes a laser positioning light for rapid positioning. Combined with an algorithm processing module, the system provides real-time feedback on the decompression effect, simplifying the operation process and improving the accuracy of judgment and surgical efficiency.

Benefits of technology

It enables flexible adjustment and precise positioning of the acquisition probe spacing, improves the accuracy of signal acquisition and the reliability of decompression effect determination, reduces surgical risks, and improves surgical success rate and patient recovery.

Abstract

The invention discloses a device for judging the decompression effect of intraoperative trigeminal neuralgia, and relates to the technical field of medical monitoring devices.The device comprises a forceps body, an acquisition probe is arranged at the tip of the forceps body, a junction box is arranged on the side, away from the acquisition probe, of the forceps body, and a distance adjusting mechanism and an auxiliary center positioning mechanism are arranged between the junction box and the forceps body; through the arrangement of the forceps body capable of adjusting the distance and the distance adjusting mechanism, the effect of flexibly adjusting the distance of the acquisition probe is achieved, the distance can be increased to detect the overall signal of the ganglion, the distance can be shortened to focus a smaller nerve area, signal differences under different distances are compared, and a compression point is accurately positioned, so that blind pressure reduction is avoided, and the detection accuracy is improved. By arranging the auxiliary center positioning mechanism, the effect of quickly positioning the center point of the forceps body and the corresponding position of the acquisition probe is achieved, medical staff is helped to accurately align to a trigeminal nerve to-be-detected area, inaccurate signal acquisition caused by positioning deviation is avoided, a trigeminal neuralgia clustering neural network algorithm is combined, a visual distribution view is generated, and the accuracy of the trigeminal neuralgia is improved. And the accuracy of decompression effect judgment and the operation efficiency are improved.
