Systems and methods are provided for applying electrical stimulation to a body by an electrode spaced from a target nerve of passage. It has been discovered that pain felt, or perceived to be felt, in a given region of the body can be treated by stimulating muscle close to a “nerve of passage” in a region that is superior (i.e., cranial or upstream toward the spinal column) to the region where pain is felt, such as in a case of post-amputation residual limb pain, or purportedly felt in the case of post-amputation phantom limb pain.

The invention relates to a multi-mode eye-brain collaborative maintenance intelligent device, and belongs to the technical field of eye-brain nursing equipment.The device is provided with an impression stimulation module, the impression stimulation module stimulates mild energy of an impression acupoint, the mild energy can be directly conducted to a paranasal sinus olfactory bulb in the deep part of a nasal cavity, the area is the starting end of paranasal sinus nerves, the paranasal sinus nerves are branches of cranial nerves, and therefore the paranasal sinus acupoint can be stimulated; the neural pathway directly extends to brain hippocampus, brain marginal tissue, pituitary gland and other core structures related to neuronutrition and brain metabolism; after stimulation, the paranasal sinus olfactory bulb and paranasal sinus nerves are activated to form a neural pathway for targeted delivery of the atomized liquid, so that the atomized particles of the brain care liquid are adsorbed on the surface of the paranasal sinus olfactory bulb and permeate into the brain along the activated neural pathway, and meanwhile, the permeability of the blood brain barrier is improved, so that the delivery resistance of the atomized liquid to related functional areas of the brain is further reduced, and the targeted delivery of the atomized liquid is realized. Precise nutrition for cranial nerves is achieved, and the problem that brain maintenance is invalid due to the fact that conventional nasal cavity atomized liquid enters the lung is thoroughly solved.

This document discloses an apparatus and method for treating conditions such as rhinitis, wherein a distal end of a probe shaft is introduced through the nasal cavity, the distal end having an end effector having a first configuration with a low profile shaped to manipulate tissue within the nasal cavity. The distal end can be positioned near a nasal tissue region having at least one nasal nerve. Once properly positioned, the distal end can be reconfigured from the first configuration to a second configuration shaped to contact and follow the nasal tissue region, and at least one nasal nerve can subsequently be ablated via the distal end. Ablation can be performed using various mechanisms (e.g., cryotherapy) and optionally under direct visualization.

This invention discloses a nerve dissector with guiding function, belonging to the field of medical device technology. It includes a dissector body with a channel concentric with its center. A Kirschner wire is installed within the channel, with one end serving as the insertion end and the other as the exit end. One end of the dissector body is a hook portion with a traction section. The exit end is located below the traction section, and the insertion end is located at the end of the dissector body furthest from the hook portion. This nerve dissector with guiding function avoids the limitations of traditional nerve dissectors, which, due to design constraints, struggle to maintain a stable position after nerve root retraction. Furthermore, if the surgeon releases the dissector or during instrument changes, the nerve root may easily spring back to its original narrow position due to loss of traction, obstructing the surgical field again and increasing the difficulty and risk of the procedure.

A posterior nasal nerve dissection and retractor for laboratory mice, belonging to the field of medical device technology, solves the technical problem of limited anatomical space and inconvenient instrument operation during posterior nasal nerve resection in laboratory mice. The solution includes clamps, a limiting rack, and a supporting leaf spring. The inner side of the tail of one clamp handle is fixedly connected to one end of the limiting rack. A first locking hole is provided on the inner side of the tail of the other clamp handle, and the other end of the limiting rack is movably inserted into the first locking hole. The supporting leaf spring is cross-arranged within the area enclosed by the clamp handles and the limiting rack on both sides. Symmetrical light guide grooves are provided between the opposing surfaces of the two clamp heads, and symmetrical grooves are provided between the opposing surfaces of the outer ends of the two clamp heads. A dissector and a retractor are detachably installed in the grooves on both sides, respectively. A protective plate is detachably installed on the outer surface of the clamp head near the retractor. This invention provides a new tool for establishing a stable and reliable experimental mouse model of posterior nasal nerve resection.

Devices and methods for more effective cryoablation of a posterior nasal nerve. The cryoablation tip of the device is paddle-shaped, with broad, flat, overall rectangular outline with notches on the sides to create a metacentric outline. One side of the cryoablation tip is conductive, while the opposing side is highly non-conductive. Corner portions of the tip are also non-conductive. Intermediate portions of the side-edge surfaces conductive, and are configured as recesses or notches in the side edge. In use, the system will be inserted into the nasal cavity of a patient, with conductive surfaces of the cryoablation tip disposed in contact with portions of the turbinate lining overlying a posterior nasal nerve, and operated to cool those portions to ablate the posterior nasal nerve. The insulative portion of the cryoablation tip protects remaining surrounding tissue from cryoablation.
