Dura mater puncture device based on multi-element signal feedback

Abstract

The invention discloses a dura mater puncture device based on multi-element signal feedback. The dura mater puncture device comprises a needle body and a needle head; the needle body is connected with the needle head; the needle body is used for acquiring real-time depth information of the tip of the needle head; the needle head is used for positioning the tissue layer where the tip end of the needle head is located by obtaining multi-element biological signals of all layers of tissue on a puncture path and penetrating through the dura mater through the electric resection and electrocoagulation functions; the needle head comprises a detection unit and an execution unit; the detection unit comprises a resistance measurement module, a resistance feedback module, an electroencephalogram monitoring module and an ultrasonic detection module; and the execution unit comprises an electric resection module and an electric coagulation module. Through real-time resistance measurement, resistance feedback, electroencephalogram monitoring and ultrasonic detection, the tissue level and the real-time position where the tip of the puncture device is located are accurately perceived, then a surgeon is assisted in rapidly finding the position of the dura mater on a puncture channel, the dura mater can be safely and reliably cut open directly through the high-power electric cutting and electrocoagulation functions, and a puncture passage for scalp, skull and dura mater is formed.

Description

technical field [0001] The invention relates to the technical field of extradural puncture, in particular to a dural puncture device based on multiple signal feedback. Background technique [0002] With the rapid development of epilepsy surgery and functional neurosurgery in my country, the use of deep EEG monitoring and neural regulation to monitor epileptic lesions or treat functional neurosurgery diseases (such as Parkinson's disease, etc.) The main form of treatment for the disease. Neurosurgeons hope to insert various types of brain electrodes (including deep brain stimulation (DBS) electrodes, stereoscopic electroencephalography (SEEG) electrodes, radio frequency and laser damage electrodes, etc.) Target), so as to send electrical stimulation, radio frequency radiation or laser pulses to the brain tissue structure around the electrode tip, and then affect the function of brain nuclei or damage the brain structure, and play a therapeutic role; or record the surrounding ...

Problems solved by technology

This puncture technique relies heavily on the experience of the surgeon. The surgeon needs to judge the level of the tip through the resistance and elasticity of the puncture needle. For example, the muscle torn during the puncture can rebound and cover the bone hole again, resulting in a drilling point. The position is not clear, so that the neurosurgeon misjudges the tissue layer where the puncture needle tip is located, chooses the wrong tool for puncture operation, and then makes the puncture position deviate, and sometimes it is more likely to cause serious complications such as brain tissue damage, which affects the treatment effect and prolongs the operation. time, so traditional surgical methods are prone to errors or corresponding complications due to the use of wrong methods

In addition, the existing electrocoagulation needles for meningeal puncture are modified from metal needles, which have poor stability and practicability in operation, and their single structure and function cannot meet the needs of precise neurosurgery.

At present, there is no integrated dural puncture device that can achieve precise positioning and cutting in the market
