The present disclosure is directed to neural interface devices and methods that accesses the subarachnoid space to enable minimally invasive modulation and recording of neural structures. Exemplary embodiments may comprise an implantable pulse generator and a microelectrode catheter. In particular embodiments, the microelectrode catheter comprises one or more stimulating and recording electrodes. Exemplary embodiments may also include methods comprising performing a lumbar puncture to access the spinal subarachnoid space and advancing microcatheter through the spinal subarachnoid space.

A lateral retractor system for forming a pathway to a patient's intervertebral disc space includes a single dilator and a retractable dual-tapered-blade assembly. The dilator may feature a narrow rectangular body for insertion at an insertion orientation parallel to the fibers of the patient's psoas muscle, at an approximate 45-degree angle to the patient's spine. The retractable dual-tapered-blade assembly consists of only two blade subassemblies, each having a blade bordered by adjustable wings, along with built-in lighting and video capabilities.The dual-tapered-blade assembly may be passed over the single dilator at the insertion orientation and rotated approximately 45-50 degrees to a final rotated orientation parallel to the intervertebral disc space before the two blade subassemblies are retracted away from one another to create the surgical pathway, while simultaneously and continuously assessing for encroachment upon one or more nerve structures within 360-degrees of the instrument. Other embodiments are also disclosed.

The application discloses a method and system for identification of blood vessels, lymph nodes and nerves in surgery, and relates to the technical field of computers, which comprises the following steps: S1, acquiring a surgery video, marking and establishing a blood vessel sample database, a lymph sample database and a nerve sample database; S2, constructing an initial identification model; S3, training the initial identification model to obtain a blood vessel identification model, a lymph identification model and a nerve identification model; S4, collecting the surgery video, and identifying and outlining the contours of blood vessels, lymph and nerves; and S5, visually displaying the surgery video and the contours to a surgeon; the system comprises a collection module, a central processing unit and a display module; the blood vessels, lymph and nerve structures under the laparoscopic surgery visual field are identified in real time by using an artificial intelligence computer model, and the visual display function is combined, so that the surgeon is provided with guidance for resection and avoidance of corresponding blood vessels, lymph nodes and nerves, the surgeon is guided to reasonably identify and resect blood vessels and lymph nodes, the blood vessels and lymph nodes that do not need to be resected are avoided, and the surgery is smoothly assisted.

The application discloses application of SKP-SC-EVs in preparation of DPN treatment drugs and belongs to the technical field of biological medicine.The SKP-SC-EVs in the application can be internalized by SCs, and can directly repair and protect damaged SCs in multiple dimensions, laying a good cell foundation for nerve regeneration, in contrast to other source EVs.In addition, through treatment of DPN model rats with the SKP-SC-EVs, it is proved that the SKP-SC-EVs can effectively improve the nerve sensory and motor functions of the DPN rats, promote the regeneration of the nerve structure and myelin sheath of the rats, enhance the nerve internal microcirculation blood flow, delay the atrophy and degenerative changes of the target muscle, and realize systematic repair of the three functional units of "nerve-vascular-muscle".The DPN treatment scheme provided by the application effectively overcomes the defects in the prior treatment schemes, i.e., single repair effect dimension and difficulty in realizing fundamental reconstruction of nerve functions and keeping long-term stability.

In an illustrative embodiment, methods and system for increasing coagulation potential and / or triggering a higher platelet activation rate in a subject via auricular neurostimulation include contacting skin of the subject with one or more therapeutic electrodes, each electrode positioned in a respective region of nerve structures of the auriculotemporal nerve (ATN), nerve structures connected to the ATN, nerve structures of the auricular branch of the vagus nerve (ABVN), or nerve structures connected to the ABVN, applying, to the electrodes, one or more stimulation patterns.

The application provides a fine forceps for minimally invasive surgery, which comprises a main forceps handle, an outside surface of the angle adjusting ring is provided with an adjusting rod mechanism, and an outside surface of the adjusting rod mechanism is provided with a forceps head mechanism. Through the adjusting rod mechanism, in use, medical staff can increase the length of the forceps rod and the adjusting threaded rod by rotating the forceps rod and the adjusting threaded rod, then the medical staff tightly abut the upper connecting buckle and the lower connecting buckle, the first threaded hole and the second threaded hole are overlapped, the outer anti-skid pad is tightly abutted with the adjusting threaded rod, and the inner anti-skid pad is tightly abutted with the forceps rod, then the upper connecting buckle and the lower connecting buckle are fixedly connected through a pair of threaded rods, the working length of the separating forceps is accurately adjusted, important blood vessels and nerve structures can be effectively avoided when reaching and operating the target area, the accuracy and safety of the surgery are significantly improved, and the surgery time is greatly shortened.
