Description

Technical Field

[0001] This invention belongs to the technical field of head cortex positioning products, and particularly relates to a head cortex partition positioning device and its usage method. Background Technology

[0002] The head contains multiple cortical regions, such as the visual cortex, auditory cortex, somatosensory cortex, and motor cortex. Identifying the cortical regions on the sides of the head helps us understand the functional organization of the brain and assists in relevant scientific research, which is of great significance for advancing neuroscience research.

[0003] Taking the auditory cortex as an example, the auditory cortex of the head is located in the temporal lobe of the brain, specifically a part of the temporal lobe cortex. The temporal lobe is a major structure of the brain, located in the temporal bone region of the skull, divided into left and right sides. Each temporal lobe contains many different areas, including the auditory cortex. Accurate localization of the auditory cortex is of great significance in neuroscience research, brain function localization, brain-computer interface research, and cognitive neuroscience research. Specifically, accurate localization of the auditory cortex can provide an important foundation for neuroscience research. By understanding the specific location and function of the auditory cortex in the brain, researchers can gain a deeper understanding of how the auditory system works, information processing, and perception mechanisms. This helps improve our understanding of auditory cognition, auditory memory, and auditory decision-making. Accurate localization of the auditory cortex is crucial for brain function localization. Accurate localization of the auditory cortex can help avoid damage to auditory functional areas during procedures, thereby maximizing the protection of patients' hearing abilities. Accurate localization of the auditory cortex is also important for research in cognitive neuroscience. By locating the auditory cortex, researchers can explore how auditory information is processed in the brain, the impact of attention on auditory perception, and the neural basis of language and music, thereby deepening their understanding of cognitive processes.

[0004] Currently, there are some difficulties and problems that need to be solved in the localization process of the auditory cortex:

[0005] 1. Uncertainty arising from individual differences: Each person's head structure, size, and shape are unique. This leads to potential differences in the location and boundaries of the auditory cortex between individuals. Therefore, accurate localization results may vary from one person to another, and individual differences need to be taken into account.

[0006] 2. Limitations of visual estimation and experience-based methods: In the past, visual estimation and experience-based methods were often used to estimate the location of brain regions. This method relies on the doctor's experience and subjective judgment. This method is not only time-consuming and labor-intensive, but also has a certain degree of subjectivity and error.

[0007] 3. Inconvenience of instrument positioning: Some positioning devices require fixing the head and the instrument, which is cumbersome, uncomfortable, and inconvenient to wear.

[0008] 4. The complexity and high cost of brain functional imaging technology: Some localization methods use brain functional imaging technology, such as functional magnetic resonance imaging (fMRI), but these technologies are complex to operate and require professional personnel to operate and interpret them. At the same time, the high cost of the equipment limits their widespread application in general hospitals.

[0009] 5. Limitations of EEG: The EEG 10-20 system placement method is a relatively simple localization method. However, due to differences in individual head shape and size, while this method is accurate for lobular regions, it is insufficient for precisely locating specific functional stimulation sites within the lobes. Currently, there are no specific points for locating the auditory cortex in the international EEG 10-20 system electrode placement methods.

[0010] In summary, the localization of the auditory cortex currently faces numerous challenges, including issues related to the accuracy, comfort, and operational complexity of the methods. Therefore, there is an urgent need to design a suitable localization aid to improve the accuracy and feasibility of auditory cortex localization. Summary of the Invention

[0036] Figure 1 This is a schematic diagram showing the positions of various points in this invention;

[0037] Figure 2 This is a schematic diagram of the wearing state of the head cortex partition positioning device proposed in this invention;

[0038] Figure 3 This is a schematic diagram of the tail section in this invention. Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0040] To address the current lack of devices that combine precise positioning, comfort, and ease of operation, this invention provides a head cortex partitioning positioning device and its usage method. This head cortex partitioning positioning device offers advantages such as precise positioning, comfort, ease of operation, simple structure, rapid positioning, cost savings, and applicability to individuals of various sizes and shapes. To further illustrate the structure of this invention, a detailed description is provided below in conjunction with the accompanying drawings:

[0041] Please see Figure 1 and Figure 2 A head cortex partitioning positioning device includes a cap 1 worn on the head, an NI tag 2, an S-line tag 3, a reference tag 4, and a vertical forward tag 5.

[0042] The cap, as the main body of this device, serves to be worn on the head. In this embodiment, the cap is a symmetrical cap made of elastic fabric that wraps around the head. Specifically, it can be made of materials such as polyvinyl chloride (PVC) or polyurethane (PU). These materials can achieve a certain degree of proportional stretching under appropriate conditions.

[0043] The NI label band is an elastic band located on the cap body. The front end of the NI label band has a mark N, and the rear end has a mark I. Marks N and I can be visible dots or designed as circular holes. In this embodiment, the NI label band is a strip extending along the centerline of the cap body; that is, the centerline is drawn on the outer surface of the cap body from front to back, and the extension of this centerline is the NI label band. The NI label band has the characteristic of proportional stretching. Marks N and I are located at the front and rear ends of the cap body, respectively. The cap body can be designed in different sizes to ensure that marks N and I can be stretched and fixed to the root of the nose at the front of the head and the external occipital protuberance at the back of the head, respectively. The cap body can be fixed by designing a chin strap. Furthermore, to ensure greater stability when wearing the hat and more reliable positioning of punctuation marks N and I, the hat body can be designed with a greater depth, where the lower edge is lower than the eye sockets and ears, and corresponding through holes can be left at the eye and ear positions. This not only helps to fix the hat body but also facilitates the alignment and fixation of punctuation marks N and I with their corresponding positions on the head.

[0044] One end of the S-line tag is connected to the NI tag section at a distance of 3 / 4 from the front end. That is, the upper hinge point of the S-line tag is located on the NI tag section. In this embodiment, the upper hinge point of the S-line tag is located on the center line of the cap body, and this hinge point is designated as point F. The distance between point F and tag point N is three times the distance between point F and tag point I. The end of the S-line tag is hinged to the NI tag section at a distance of 3 / 4 from the front end, and the S-line tag can rotate circumferentially around the hinge point. In this embodiment, a buckle is installed at point F on the cap body, and the S-line tag can rotate 360° around this buckle, thus allowing the angular position of the S-line tag on the side of the cap body to be adjusted based on point F. The other end of the S-line tag is detachably glued to the front side of the cap body to achieve fixation on the outer side of the cap body after the S-line tag has been aligned. The alignment mentioned here refers to the adjustment of the position of the other end of the S-line tag with the buckle as the pivot point.

[0045] The reference marker is mounted to the cap in a height-adjustable manner. This mounting method ensures that, after the cap is worn in the correct head position, the reference marker and the side vertical projection line pass in a straight line through two reference points on the side of the head. Please refer to [link / reference]. Figure 3In this embodiment, specifically, the rear of the cap body is provided with a vertically extending tail 6. This tail can be an extension of the rear of the cap body or an independent extension connected to the rear of the cap body. In this embodiment, this tail is a non-elastic long strip-shaped body, and a rear end buckle component 7 with vertically adjustable height is installed on the tail. The rear end of the reference label is connected to the rear end buckle component. Further, a toothed chain extending along its length is fitted on this tail, and a slider adapted to it is fitted on the toothed chain as the aforementioned rear end buckle component. The toothed chain and the slider are two core components of the zipper assembly in the prior art. The toothed chain is the core part of the zipper, consisting of a series of metal or plastic teeth. The teeth are usually curved, with protruding teeth on one side and grooves on the other side, so that two toothed chains can interlock. The toothed chain can be made of metal, such as aluminum or zinc alloy, or plastic, such as nylon or polyester. The slider is the part used to open and close the zipper, and it is usually made of metal or plastic. The slider has a handle, which can be manually slid along the path of the toothed chain. The slider also has two slots for guiding the engagement of the toothed chain. The zipper can be opened or closed by sliding the slider. In this embodiment, the slider is directly hinged to the end of the reference label, which can rotate 360° around this hinge point. The other end of the reference label is a free end, which can extend at least to the front of the ear and can be detachably connected to the hat body.

[0046] The vertical forward tag is installed on the reference tag in a way that allows adjustment along the straight extension direction of the reference tag. The vertical forward tag is perpendicular to the reference tag, and the S-line tag and the vertical forward tag intersect at the side of the cap. That is, the side vertical projection of the vertical forward tag is always perpendicular to the side vertical projection of the reference tag, and the vertical forward tag can be adjusted in the front-back direction in this positional relationship, using the reference tag as the adjustment basis. In this embodiment, specifically, the reference tag has a slide section extending along the straight extension direction of the reference tag, and a slider that moves along the slide groove is mounted on the slide section. The lower end of the vertical forward tag is mounted on the slider, and the upper end of the vertical forward tag is detachably bonded to the upper side of the cap. In this embodiment, further, the slide section is selected as a toothed chain extending along the reference tag, and the slider is selected as a slider adapted to the toothed chain. The slider is connected to the lower end of the vertical forward tag by at least two buckles, thereby achieving the adjustment of the front-back position of the vertical forward tag while ensuring the perpendicular angle between the vertical forward tag and the reference tag.

[0047] The structural details regarding the toothed chain and slider described in this embodiment are merely one example of a linear adjustment mechanism, and are not limited to this. For instance, a slide rail can be formed along the side of the reference strip, and a slider component can be fitted into this slide rail. Guided by the slide rail, the slider component moves linearly and is then fixed in place using adhesive tape after reaching the designated position. The toothed chain and slider, working together, inherently prevent sliding. To prevent the slider from sliding freely after adjustment to the accurate position, adhesive tape can be used for further fixation. Flexible plastic parts with slide rails are readily available through external purchase or custom design in the prior art. Alternatively, the reference strip can be an elastic, elongated plastic sheet, with its body serving as the slide rail. The slider is a sliding sleeve-shaped block fitted onto it. This type of fitting can be referenced from the buckle structure used in the prior art for securing the extension end of a backpack.

[0048] The S-line tag, reference tag, and vertical forward tag mentioned above are straight strips without elasticity. In this embodiment, the S-line tag, reference tag, and vertical forward tag are ribbon-like components with one end connected to other parts in a normal manner, and the other end being a free end that can be fixed to the hat body. They can be made of a sheet of flexible plastic of a certain width, or a sheet of fabric of a certain width, ensuring that they only have a bending function. Bending means that the side of the straight strip forms a curved extension that can fit against the outer surface of the hat body, while the vertical projection of its side is always a straight line. The vertical projection mentioned here refers to the projection in a direction perpendicular to the side of the head.

[0049] Regarding the fixing method of the free ends of the S-line tag, the reference tag, and the vertical forward tag, in this embodiment, the front side of the hat body is provided with a nylon adhesive area in the shape of a planar region for bonding the S-line tag and the reference tag. When the hat body is worn on the head and adjusted to a correct position, the nylon adhesive area in the planar region is located behind the outermost edge of the eye socket, thus achieving fixation of the free ends of the S-line tag and the reference tag after position adjustment. This planar region ensures that the free ends of the S-line tag and the reference tag can be fixed within a certain range. The fixing method of the free end of the vertical forward tag is the same. A nylon adhesive area in the shape of a planar region is provided at the top center line of the hat body to fix the free end of the vertical forward tag. The nylon adhesive area in the planar region on the outer surface of the hat body is the fleece surface of a nylon hook and loop fastener, which can be sewn onto the hat body. The inner sides of the ends of the S-line tag, the reference tag, and the vertical forward tag are provided with hook surfaces that can be bonded thereto.

[0050] The aforementioned wearable component, which uses the hat body as the base for wearing and the parts that establish positioning with the head, and the S-line tag, reference tag, and vertical forward tag installed on it and whose positions are adjustable and fixed after adjustment, constitute a positioning accessory that can determine a precise marking point (the intersection of the S-line tag and the vertical forward tag in a fixed position) on the side of the hat body. After the first wear, the positional relationship between the S-line tag, reference tag, and vertical forward tag and the hat body can remain fixed. In the subsequent process of determining the marking point for the same individual, it is only necessary to establish the positional relationship between the hat body and the individual's head to quickly determine the target point.

[0051] In this device, the number and design position of the tags can be increased to provide positioning functions for other different areas. Furthermore, a vertical rear tag 8 is installed on the reference tag in a manner adjustable along its straight extension direction. The vertical rear tag is perpendicular to the reference tag and located behind the vertical front tag. The upper end of the vertical rear tag is detachably connected to the NI tag section at point P. A side-end buckle component with vertically adjustable position is installed on the vertical front tag. The side-end buckle component is connected to one end of the C-line tag 9, and the end of the C-line tag can rotate circumferentially around the side-end buckle component. The other end of the C-line tag is detachably connected to point P. This additional vertical rear tag has the same installation method and free end connection method as the vertical front tag. The C-line tag end is installed on the vertical front tag in the same way as the reference tag end. The vertical rear tag and C-line tag use the same materials and shape design principles as the S-line tag, reference tag, and vertical front tag described above. The design of the vertical rear label and the C-line label creates a marking line on the side with the C-line label fixed as the area division line, giving the device a new marking function.

[0052] The usage method in this embodiment is as follows:

[0053] S1. Place the cap on your head, aligning the NI label with the midline of your head, the N label with the root of the nose at the front of your head, and the I label with the external occipital protuberance at the back of your head. The root of the nose is the depression between the nose and forehead, also known as the "root of the nose." It is the point where the bridge of the nose connects to the forehead. The external occipital protuberance is a specific raised area at the back of the head, also called the "external occipital protuberance" or "external occipital tuberosity." It is close to the midline of the back of the skull and is a protrusion of the occipital bone, which can be felt by touching the back of the head or massaging the head. The root of the nose and the external occipital protuberance are two clearly identifiable positioning points on the head. During the cap-wearing process, the operator needs to align the N and I labels with these two positions respectively.

[0054] S2. Straighten the S-line tag with its free end pointing towards the posterior end of the eye socket and secure it. Straightening here ensures the S-line tag is a straight line in the lateral vertical projection of the head. The posterior end of the eye socket is the edge of the eye socket corresponding to the outer corner of the eye. After the front end of the S-line tag points to this position, secure the S-line tag using the Velcro fastener between the front end of the S-line tag and the cap body.

[0055] S3. Adjust the horizontal position of the reference tape so that it is straight and passes through both the lower edge of the eye socket and the upper edge of the external auditory canal. Fix the reference tape in this position. The lower edge of the eye socket is the lowest point of the eye socket, and the upper edge of the external auditory canal is the highest point of the external auditory canal. Adjust the reference tape to a suitable horizontal position using the rear buckle, ensuring that one side of the reference tape passes through both points simultaneously. Fix the reference tape in this position. With the reference tape fixed, the vertical projection of the head to the side is a straight line.

[0056] S4. Adjust the position of the vertical forward tag on the reference tag so that the vertical forward tag passes through the mandibular crest on the side of the head. The mandibular crest is a point that can be felt by touch. That is, the vertical forward tag passes through the point of the mandibular crest on the side of the head while perpendicular to the reference tag. In this embodiment, during the specific operation, the rear edge of the vertical forward tag can be used as the reference line, so that the rear edge of the vertical forward tag passes through the point of the mandibular crest on the side of the head. After the vertical forward tag is adjusted to the corresponding position, it is fixed to the cap body by the nylon hook and loop fastener at its upper end. The fixed vertical forward tag should be straight in the vertical projection on the side of the head.

[0057] S5. Mark point O at the intersection of the vertical forward-facing label and the S-line label, and mark a target area 2cm long and 1cm wide using the S-line label as its upper long side. This target area represents the auditory cortex of the head. In practice, mark point O at the intersection of the lower edge of the S-line label and the rear edge of the vertical forward-facing label. To make this target area more intuitive after identification, a nylon hook-and-loop fastener area is provided on the hat body near this target area. This area is larger than and can cover the target area. After mark point O is determined, a hook-and-loop marker block 2cm long and 1cm wide is set and fixed using mark point O and the lower edge of the S-line label as positioning conditions. This area represents the auditory cortex region.

[0058] After the planar marker block is fixed, during repeated wear of the device on the same person, it is only necessary to align the NI marker band of the cap with the midline of the head, the N marker with the root of the nose at the front of the head, and the I marker with the external occipital protuberance at the back of the head. This will ensure that the planar marker block is accurately aligned with the auditory cortex of the head, eliminating the need for repeated calibration.

[0059] S6. The practical method for marking the vertical posterior marker and the C-line marker is the same as the method for determining the marker point O described above. That is, with the vertical anterior marker fixed, the vertical posterior marker is fixed in the same way. The positioning principle of the vertical posterior marker is to fix its upper end behind the mastoid process of the head to the midline of the cap. The mastoid process is a cone-shaped projection that protrudes from the bottom surface of the mastoid part of the temporal bone. It can be felt on the body surface and is located behind the external auditory canal and outside the styloid process. The intersection of the fixed vertical posterior marker and the midline of the cap is point P. After adjusting the connection point of the C-line marker and the vertical anterior marker to point P, the other end is pointed towards point P and fixed. The C-line marker forms a marker line, which can determine the central sulcus line of the head. The central sulcus is a landmark anatomical landmark in cranial imaging. With the central sulcus as the boundary, the brain is divided into the frontal lobe and the parietal lobe. The gyri in front of and behind the central sulcus are the precentral gyrus and the postcentral gyrus, respectively. Accurate identification of the central sulcus is important for a better understanding of the anatomy of the brain and for functional inference in case of damage.

[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
