The application discloses a lumbar puncture auxiliary mechanism and a use method thereof. The lumbar puncture auxiliary mechanism comprises a main body assembly, a supporting shell fixed to one side of a positioning disc, and a puncture needle penetrating through the positioning disc and the supporting shell. The main body assembly is provided with an adjusting assembly in the supporting shell. The adjusting assembly comprises a driving element arranged on one side of the positioning disc, a transmission element arranged on one side of the driving element, and an adjusting element arranged on one side of the transmission element. The adjusting element comprises a limiting shell fixed to the inner wall of the supporting shell, a rack sliding in the limiting shell, and a first spring fixed to the end of the rack. The adjusting assembly can intermittently supply the puncture needle, so that the puncture needle can smoothly break through the yellow ligament without improper force. The puncture process can be judged, so that the time when the puncture needle enters the epidural space and the subarachnoid space can be accurately grasped, and the accidental damage to the human body is reduced.

Devices, systems and methods for reducing migration of leads, catheters and similar devices are provided. In particular, devices, systems and methods are provided for creating a slack anchor which assists in maintaining the lead or catheter in a desired position. In some embodiments, the slack anchor is created within the epidural space. When targeting nerve anatomy within the spinal column or in the vicinity of the epidural space, anchoring within the epidural space allows the associated lead or catheter to be anchored as close to the target therapy site as desired or possible. By anchoring close to the target therapy site, the risk of movement or migration is significantly reduced or eliminated.

This invention discloses an epidural anesthesia assistance method and system based on pressure curve characteristics, including a data acquisition and preprocessing module, an anatomical layer segmentation module, a multidimensional feature extraction module, a template matching and initial classification module, a Bayesian probabilistic inference and fusion decision-making module, a risk assessment and feedback output module, and an online adaptive update module. By utilizing real-time pressure monitoring, negative pressure recognition, and biometric frequency extraction technologies, it assists in determining the position of the epidural puncture needle, significantly reducing the rate of epidural puncture mispuncture and improving clinical safety. Through a Bayesian online learning update mechanism, the model parameters can be continuously iterated based on clinically labeled data, adapting to different operator habits and sensor drift, achieving long-term stable operation and individualized calibration. This invention is easy to integrate and has low hardware costs, facilitating large-scale clinical deployment.

In some embodiments, disclosed herein are systems and methods of treating a patient that can include the steps of accessing the sphenopalatine fossa, and cannulating the inferior orbital fissure from the sphenopalatine fossa to access the retro-orbital space. The sphenopalatine fossa can be accessed via various routes, including percutaneously. Accessing the sphenopalatine fossa can include the step of inserting a needle-catheter system into the sphenopalatine fossa. Integrated needle-catheter systems as described herein can also be configured to access the trigeminal ganglion, epidural space, intrathecal space, and other desired anatomical locations.
