Description

Technology Field

[0001] The present disclosure relates to a surgical guide indicator made of a radiopaque material. Background Technology

[0002] In procedures using radiographic imaging equipment, it is crucial to accurately identify the puncture sites at the treatment site. Conventionally, a method in which the operator repeatedly takes radiographic images to individually verify each puncture site is primarily used. This method causes problems such as increased radiation exposure for both patients and medical staff, and has the disadvantage of prolonging the procedure time. Furthermore, existing indicators make it difficult to identify multiple puncture sites at once, and lack identification markers to distinguish each site, resulting in reduced efficiency and intuitiveness of the procedure. For example, Korean Patent Publication No. 10-2024-0140380 discloses a probe for nerve block procedures. In particular, in areas where anatomical structures are repeatedly arranged, such as the spine, a separate device is required to rapidly identify puncture sites corresponding to each segment. Against this backdrop, the need arises for a procedural guide indicator that includes a location display section and an identification marker section to enable the simultaneous identification of multiple puncture sites on radiographic images. The problem to be solved

[0003] The purpose of one embodiment is to provide a guide indicator for a procedure that includes a central axis, a position indicator, and an identification marker, and guides the identification of multiple puncture locations on a radiation image together with the identification marker, in order to solve the problems of increased radiation exposure to patients and medical staff due to repeated radiation exposure, delay in procedure time, and difficulty in identifying multiple puncture locations at once during a procedure using radiation imaging equipment. means of solving the problem

[0007] In an indicator according to one embodiment, the anatomical structure of the treatment target area may include one or more vertebral segments, and a preset interval may correspond to the average interval between vertebral segments so as to collectively specify the puncture location for one or more vertebral segments on a radiographic image.

[0008] In an indicator according to one embodiment, at least one end of one or more position indicators may be provided with a guide portion formed inwardly concave so that a surgical needle inserted into a puncture position can be seated in the correct position without slipping.

[0023] FIG. 1 is an example of a usage state of a surgical guide indicator according to one embodiment, FIG. 2a is an example of a surgical guide indicator according to one embodiment, and FIG. 2b is another example of a surgical guide indicator according to one embodiment.

[0024] Referring to FIGS. 1 to 2b, in at least one embodiment of the present disclosure, a surgical guide indicator (1) relates to a device for guiding the puncture location of a target area during a surgical procedure using a radiographic imaging device. The surgical guide indicator (1) can visually display the puncture location on an image obtained through the radiographic imaging device.

[0025] In one embodiment, the indicator (1) may include a central axis portion (10), a handle portion (11), a position indicator portion (20), and an identification marker portion (30). The indicator (1) may form an integrated structure by combining each component based on the central axis portion (10). The indicator (1) may be arranged such that a plurality of position indicator portions (20) intersect along the central axis portion (10). The indicator (1) may have an identification marker portion (30) positioned corresponding to each position indicator portion (20). The indicator (1) may have a handle portion (11) extending from one side of the central axis portion (10) to facilitate gripping and operation by the operator. The indicator (1) may be formed of a radiopaque material so that it can be clearly projected onto a radiation image in a surgical environment using radiation imaging equipment. The indicator (1) may be designed to collectively identify multiple puncture positions with only a single radiation shot. The indicator (1) allows the operator to quickly calculate the target puncture location by confirming the identification marker (30) and the location indicator (20) on the image. In the present disclosure, opacity refers to the property that radiation does not penetrate the material or only penetrates a very small portion of it, and may also be referred to as radioopaque.

[0026] In one embodiment, the central axis portion (10) may serve as a main frame supporting the entire structure of the indicator (1). The central axis portion (10) may be integrally extended along the longitudinal direction of the indicator (1) to provide a reference axis for the connection of each component. The central axis portion (10) may form a structural base to which other components, such as the position indicator portion (20), the handle portion (11), and the identification marker portion (30), are connected. The central axis portion (10) may be designed to have sufficient strength to ensure positional stability of the indicator (1) in a surgical environment. The central axis portion (10) may be made of a radiopaque material so that it can be clearly identified in a radiographic image.

[0027] In one embodiment, the central axis portion (10) may be formed as a linear body extending in one direction. The central axis portion (10) may be implemented as a straight rod or flat plate structure. The central axis portion (10) may be designed to maintain a constant thickness and width along the longitudinal direction. The central axis portion (10) may have grooves or connecting portions formed on its surface so that the position indicator portion (20) can be arranged in an intersecting direction. The central axis portion (10) may be positioned parallel to the anatomical arrangement of the treatment target area.

[0028] In one embodiment, the central axis portion (10) may be formed by including a radiopaque material, such as a metal, a radiopaque alloy, or a radiopaque synthetic resin, so that it can be clearly visible in an image when irradiated with radiation such as X-rays. The central axis portion (10) may be made of various radiopaque materials, such as stainless steel, titanium, tungsten alloy, bismuth alloy, barium-containing synthetic resin, and bismuth-containing synthetic resin. The central axis portion (10) can form a clear contrast with surrounding tissue in a radiation image. The central axis portion (10) can optimize identifiability in an image by adjusting the thickness and width of the radiopaque material. The visualization characteristics of the central axis portion (10) in an image can be verified through a radiation transmission experiment.

[0029] In one embodiment, the handle portion (11) may be formed by extending from the central axis portion (10) in a direction intersecting the longitudinal direction. The handle portion (11) may be ergonomically designed so that the operator can grip the indicator (1) with their hand. The handle portion (11) may be coupled to one end of the central axis portion (10) to enhance the operator's ease of operation. The handle portion (11) may be implemented in various cross-sectional shapes, such as cylindrical, flat, or curved shapes. The handle portion (11) may include an anti-slip pattern or surface roughness.

[0030] In one embodiment, the handle portion (11) may be configured to allow the operator to stably manipulate and support the placement position on the treatment target area while holding the indicator (1) with their hand. The handle portion (11) may be designed with sufficient width and thickness so that the operator can stably grip it with one hand or both hands. The handle portion (11) may be extended to a sufficient length so that the operator's hand holding it is separated from the radiation irradiation area when the main body of the indicator (1) is located within the radiation irradiation area. The handle portion (11) may be extended beyond a certain distance from the connection portion with the central axis portion (10) to minimize radiation exposure. The handle portion (11) may include a marking line or a protrusion that guides the operator's hand position.

[0031] In one embodiment, the handle portion (11) may be formed integrally with the central shaft portion (10), or modified to be rotatable or detachable through a hinge or coupling module. The handle portion (11) may be inserted into or fastened to the central shaft portion (10) using a coupling module. The handle portion (11) may be rotated at a certain angle through a hinge structure. The handle portion (11) may be designed to be detachable for storage or replacement as needed. The handle portion (11) may be provided in multiple variations with changed length, angle, and coupling method to suit various clinical environments.

[0032] In one embodiment, one or more position indicators (20) may be arranged spaced apart by a predetermined interval along the longitudinal direction of the central axis (10). The position indicators (20) may extend in a direction orthogonal to the central axis (10) to indicate a position corresponding to the anatomical structure of the area to be treated. Multiple position indicators (20) may be arranged at regular intervals to visually distinguish each puncture position. The position indicators (20) may be attached to the surface of the central axis (10) by insertion, welding, or integral molding.

[0033] In at least one embodiment of the present disclosure, the pre-set interval may be designed to correspond to the average interval between anatomical structures, for example, between vertebrae. The interval between the position indicators (20) may be calculated as the average distance between vertebrae based on clinical data. The position indicators (20) may be arranged at different intervals depending on the application area, such as the lumbar spine, thoracic spine, and cervical spine. The position indicators (20) may be designed to minimize the interval error so that they can be accurately matched with the vertebrae in a radiographic image. The position indicators (20) may be modified into a structure that allows for interval adjustment.

[0034] In at least one embodiment of the present disclosure, one or more position indicators (20) may be composed of linear members that extend in both directions relative to the central axis (10) to form a cross shape with the central axis (10), or extend only in one direction to form a comb shape. The position indicators (20) may be symmetrically arranged on both sides of the central axis (10) to form a cross-shaped structure. The position indicators (20) may be arranged only on one side of the central axis (10) to be implemented as a comb-shaped structure. The position indicators (20) can simultaneously display left-right symmetrical puncture positions through the cross-shaped structure. The position indicators (20) can display only one direction of puncture positions through the comb-shaped structure. The position indicators (20) may selectively apply a cross shape or a comb shape depending on the clinical purpose.

[0035] In at least one embodiment of the present disclosure, at least one end of one or more position indicators (20) may be provided with a guide portion formed inwardly concave so that a surgical needle inserted into a puncture position can be seated in the correct position without slipping. The guide portion of the position indicator (20) may be designed in a groove shape so that the tip of the needle can be fixed in an accurate position when the needle is inserted. In one embodiment, the guide portion may be formed in a V-shaped or U-shaped groove shape and may serve to support the needle to prevent slipping and maintain an accurate puncture path when the surgical needle enters the target area. The guide portion may be provided in various sizes to match the diameter of the needle. The depth and width of the groove of the guide portion may be adjusted so that the needle insertion angle can be maintained at a constant level. The guide portion may be modified into a replaceable or clip-type structure.

[0036] In at least one embodiment of the present disclosure, an identification marker (30) may be provided corresponding to each of one or more position indicators (20). The identification marker (30) is matched one-to-one with each position indicator (20) so that the puncture location can be clearly distinguished in the image. The identification marker (30) may be formed directly on the surface of the position indicator (20) or the central axis (10). The identification marker (30) may be positioned so that the operator can quickly check the identification number in the image.

[0037] In at least one embodiment of the present disclosure, the identification marker (30) may include at least one of a number, a letter, or a figure. The identification marker (30) may be formed by engraving, printing, or laser marking a unique number or letter on each position indicator (20). In at least one embodiment of the present disclosure, the identification marker (30) may be formed in the form of a perforation that penetrates a portion of the material of the central axis (10) or the position indicator (20). The identification marker (30) may be implemented as a circular, square, or other shaped perforation. The identification marker (30) may distinguish each position indicator (20) by varying the size, arrangement, or pattern of the perforations. The identification marker (30) may be designed in a clear form so that the operator can intuitively recognize it on the radiographic image.

[0038] In at least one embodiment of the present disclosure, the identification marker (30) may be configured to be distinguished by a bright contrast that contrasts with the surrounding metal part in the image when radiation is transmitted. The identification marker (30) may be designed to allow radiation to pass through by applying perforations or a low-density material. The identification marker (30) may appear as a bright part in the radiation image, forming a clear contrast with the dark part of the metal part. The identification marker (30) may be designed with standardized perforation locations and sizes to prevent misrecognition during image reading. The identification marker (30) may be experimentally verified to ensure optimal contrast according to the resolution and contrast ratio of the radiation image.

[0039] In at least one embodiment of the present disclosure, one or more position indicators (20) may be arranged spaced apart by a predetermined interval along the longitudinal direction of the central axis (10). The position indicators (20) may be arranged repeatedly at regular intervals along the longitudinal direction of the central axis (10). The spacing between the position indicators (20) may be designed to correspond to the average distance between anatomical structures, for example, between vertebrae. The position indicators (20) may be extended in a direction orthogonal to the central axis (10) and projected parallel to an anatomical reference line in a radiographic image. A plurality of position indicators (20) may be arranged on the same plane to form a grid-shaped visual coordinate system in the image. Each position indicator (20) may be linked with an identification marker (30) to clearly distinguish each position in the image.

[0040] In one embodiment, the position indicator (20) may be composed of a linear member that extends in both directions relative to the central axis (10) to form a cross shape, or extends only in one direction to form a comb shape. The position indicator (20) may be symmetrically arranged on both sides of the central axis (10) to create a cross-shaped structure. The position indicator (20) may be arranged only on one side of the central axis (10) to create a comb-shaped structure. The cross-shaped structure provides a left-right symmetrical reference line in the image, allowing the operator to easily recognize the anatomical central axis. The comb-shaped structure extends only in one direction, thereby increasing space utilization in environments where the treatment area is limited.

[0041] In one embodiment, the pre-set interval may be designed to correspond to the average interval between anatomical structures, for example, between vertebrae. The interval between the position indicators (20) may be set to match the average distance between vertebrae (e.g., lumbar 1-2 cm, cervical 0.8-1.2 cm, etc.) based on clinical data. The interval of the position indicators (20) may be provided as a plurality of models that are adjusted differently depending on the application area. The interval of the position indicators (20) may be customized according to the deformation of anatomical structures or the patient's body shape.

[0042] In one embodiment, an identification marker (30) may be provided corresponding to each of the one or more location indicators (20). The identification marker (30) may be placed at the same location or an adjacent location as each location indicator (20). The identification marker (30) may be molded integrally with the location indicator (20) or combined with a separate attachment structure. The identification marker (30) may be implemented in various forms, such as numbers, characters, or shapes, so as to uniquely identify each location indicator (20).

[0043] In one embodiment, the identification marker (30) may include at least one of a number, a letter, or a shape. The identification marker (30) may be displayed as a sequence of Arabic numerals such as 1, 2, 3, Latin letters such as A, B, C, or alphabetic letters. The identification marker (30) may be implemented as a geometric symbol such as a triangle, a circle, or a square. The identification marker (30) may be displayed in combination with numbers and letters. Through the identification marker (30), the operator can immediately and intuitively recognize each location by simply checking the identification marker (30) directly marked on the corresponding location indicator (20), without needing to calculate which position it is by counting from the top among the multiple location indicators (20).

[0044] In one embodiment, the identification marker (30) may be formed in the form of a perforation that penetrates a part of the material of the central axis (10) or the position indicator (20), so as to be distinguished by a bright contrast that contrasts with the surrounding metal part in the image when radiation is transmitted. The identification marker (30) may be manufactured by forming a circular, square, or number-shaped perforation in the central axis (10) or the position indicator (20). The perforated part of the identification marker (30) may transmit radiation and appear as a bright area in the image. The identification marker (30) may maximize the contrast with the surrounding metal part so that the operator can quickly verify the identification number when reading the image.

[0045] In one embodiment, due to this structure, the operator can verify a visual coordinate system in which the human anatomical structure, the position indicator (20) of the indicator (1), and the identification marker (30) are superimposed on the radiographic image. The operator can intuitively identify the point where the spinal segment and the position indicator (20) coincide in the image output on the display device (300). The operator can clearly distinguish each puncture location through the number or symbol displayed on the identification marker (30). The operator can identify multiple puncture locations simultaneously within a single image and quickly establish a procedure plan.

[0046] In one embodiment, at least one end of the position indicator (20) may be provided with a guide portion that is inwardly concave. The guide portion may be formed in a groove shape at the end of the position indicator (20). The guide portion can physically support the needle so that it does not detach from the position indicator (20) when the needle is inserted. The guide portion may be designed in various sizes to match the diameter of the needle.

[0047] In at least one embodiment of the present disclosure, the guide portion may be formed in the shape of a V-shape or a U-shape groove and may serve to support the needle to prevent slippage and maintain an accurate puncture path when the needle enters the target area. The guide portion may guide the alignment of the needle's central axis through the V-shape groove. The guide portion may stably fix the needle so that it does not shake from side to side through the U-shape groove. The guide portion may ensure consistency of the puncture path by maintaining a constant needle insertion angle.

[0048] In one embodiment, the handle portion (11) provides an area for the operator to grip with their hand, and can be extended to a sufficient length so that the operator's hand is separated from the radiation area when the main body of the indicator (1) is located within the radiation area. The handle portion (11) can be extended beyond a certain distance from the central axis portion (10) so that the operator's hand is not exposed to the radiation area. The handle portion (11) is ergonomically designed so that fatigue can be minimized even when the operator grips it for a long time. The handle portion (11) may include an anti-slip surface treatment or a protruding structure to increase grip stability.

[0049] In at least one embodiment of the present disclosure, this physical guidance function can increase stability during needle insertion and improve the accuracy of the procedure. By ensuring the needle rests on the guide portion, it is possible to prevent the needle from slipping or deviating from its position during the insertion process. The insertion path of the needle is maintained consistently, allowing it to reach the target site accurately. The physical guidance function can provide consistent procedure results regardless of the operator's skill level.

[0050] In one embodiment, by performing a single shot using radiation equipment, image data can be generated in which a position indicator (20) and an identification marker (30) are projected along with anatomical structures. The radiation imaging equipment (200) can irradiate radiation while the indicator (1) is placed on the surface of the patient's skin. The radiation can simultaneously penetrate the anatomical structures of the human body and the metal part of the indicator (1) to output image data to a display device (300). In the image data, the spinal segment, the position indicator (20), and the identification marker (30) can be clearly displayed on the same plane.

[0051] In at least one embodiment of the present disclosure, the operator can collectively calculate puncture locations by verifying the identification number of a location indicator (20) that corresponds to a target lesion (spinal segment) on the image data. The operator can identify the point where the spinal segment and the location indicator (20) overlap on the image. The operator can verify the number or symbol of the identification marker (30) corresponding to each location indicator (20). The operator can calculate multiple puncture locations at once and establish a procedure plan without repetitive radiographic imaging.

[0052] In one embodiment, a surgical needle can be inserted into the guide portion of the position indicator (20) corresponding to the calculated puncture position and advanced to the target depth. The operator can accurately position the needle in the guide portion of the position indicator (20) corresponding to the calculated puncture position. The operator can insert the needle along the guide portion and advance it stably to the target depth. During the needle insertion process, the guide portion prevents the needle from shaking, thereby increasing the accuracy of the puncture.

[0053] In one embodiment, as described above, multiple puncture sites can be simultaneously identified using only a single radiographic image, thereby contributing to a reduction in procedure time and radiation exposure. The single-shot method can significantly shorten procedure time compared to the conventional repeated-shot method. By identifying multiple puncture sites with a single shot, radiation exposure to patients and medical staff can be minimized. The single-shot method can increase the operational efficiency of the operator and enhance patient safety.

[0054] In at least one embodiment of the present disclosure, the procedure environment may be configured to include a procedure guide indicator (1), a radiation imaging device (200), and a display device (300). The procedure environment may be implemented in a structure in which the procedure guide indicator (1) is placed directly on the surface of the patient's skin. The radiation imaging device (200) may be positioned above to cover the area to be treated and the area where the indicator (1) is located. The display device (300) may be connected to the radiation imaging device (200) via wired or wireless means to output a transmission image in real time. The procedure guide indicator (1) may be designed in a structure including a central axis portion (10), a handle portion (11), a position indicator portion (20), and an identification marker portion (30). The radiation imaging device (200) may be implemented as a C-arm or a mobile fluoroscopy device. The display device (300) may be configured as a monitor, a tablet, or a medical image output device. Each component interacts with others to allow the operator to intuitively verify the puncture location on the image. The procedure environment can be optimized to identify multiple puncture locations simultaneously with a single shot. The procedure environment can be designed to minimize radiation exposure for both patients and medical staff. The arrangement and connection methods of the components can be modified to suit various clinical environments.

[0055] In at least one embodiment of the present disclosure, the procedure guide indicator (1) may be placed on the surface of the skin of the patient's treatment area. The procedure guide indicator (1) may be attached to the skin surface while being held securely by the operator using the handle portion (11). The procedure guide indicator (1) may have a central axis portion (10) aligned parallel to the alignment direction of the spine. The procedure guide indicator (1) may have position indicator portions (20) arranged at intervals corresponding to anatomical structures to clearly indicate the target puncture location on the skin surface. The procedure guide indicator (1) allows each position indicator portion (20) to be distinguished through an identification mark portion (30). The procedure guide indicator (1) may include an anti-slip guide portion to provide physical stability during needle insertion.

[0056] In at least one embodiment of the present disclosure, the radiation imaging equipment (200) may be positioned above to irradiate radiation toward an area encompassing the treatment target area and an indicator (1) mounted thereon. The radiation imaging equipment (200) may set the irradiation range to capture the entire treatment target area of ​​the patient and the area including the indicator (1) at once. The radiation imaging equipment (200) may adjust the irradiation intensity and irradiation angle so that the indicator (1) and anatomical structures are clearly distinguished in the image. The radiation imaging equipment (200) may acquire a transmission image containing multiple puncture locations in a single shot. The radiation imaging equipment (200) may be configured so that image data is transmitted to a display device (300) in real time.

[0057] In one embodiment, the display device (300) may be connected to the radiation imaging equipment (200) via wired or wireless connection and positioned to output a projected image of the internal bone structure and the indicator (1) generated by the transmitted radiation in real time. The display device (300) may display the acquired transmitted image in high resolution. The display device (300) may clearly distinguish and display the position indicator (20) and the identification marker (30) of the indicator (1) on the image. The display device (300) provides a real-time state in which the anatomical structure and the indicator (1) are superimposed within the image, allowing the operator to intuitively check the puncture location. The display device (300) may include various image processing functions such as image magnification and brightness adjustment. The display device (300) may provide a user interface to enable medical personnel to quickly calculate the puncture location on the image.

[0058] In at least one embodiment of the present disclosure, the operator may position the indicator (1) on the skin surface such that the central axis portion is parallel to the alignment direction of the spine. The operator may grasp the handle portion (11) to press the indicator (1) against the patient's skin surface. The central axis portion (10) of the indicator (1) may be aligned parallel to the anatomical alignment of the spine. The indicator (1) may clearly indicate the target puncture location on the skin surface by arranging the position indicator portion (20) according to the average spacing between the vertebrae. The indicator (1) allows each position indicator portion (20) to be distinguished through the identification mark portion (30). The indicator (1) may include an anti-slip guide portion to provide physical stability during needle insertion.

[0059] In one embodiment, the radiation imaging equipment (200) can acquire a transmission image by irradiating the area where the indicator (1) is mounted with radiation once. The radiation imaging equipment (200) can set the irradiation range to include the indicator (1) and the entire area to be treated. The radiation imaging equipment (200) can generate an image in which the indicator (1) and anatomical structures are projected simultaneously in a single shot. The radiation imaging equipment (200) can secure clear contrast in the image by adjusting the irradiation intensity and irradiation angle. The radiation imaging equipment (200) can transmit the acquired image to a display device (300) in real time.

[0060] In one embodiment, the display device (300) can display the acquired image on a screen. The display device (300) can clearly display the position indicator (20) and the identification marker (30) of the indicator (1) within the image. The display device (300) can provide a state in real time in which the anatomical structure and the indicator (1) are superimposed on the image. The display device (300) may include various image processing functions such as image magnification and brightness adjustment. The display device (300) may provide a user interface so that medical personnel can quickly calculate the puncture location on the image.

[0061] In one embodiment, the output image may display anatomical structures of the human body, the position indicator of the indicator (1), and the perforated identification marker on the same plane with clear contrast. The output image may display anatomical structures, such as spinal segments, and the position indicator (20) of the indicator (1) superimposed on the same plane. The identification marker (30) may be distinguished by bright contrast in the image due to its perforated structure. The position indicator (20) within the image may appear as a distinct linear pattern due to its radiopaque material. Each position indicator (20) and the identification marker (30) in the image allows for clear verification of their relative positions with respect to anatomical structures. The image may be designed so that the operator can intuitively calculate the target puncture location.

[0062] In at least one embodiment of the present disclosure, the operator can collectively calculate and identify individual puncture locations corresponding to a plurality of spinal segments by matching them with identification numbers based on a single image output to a display device (300). The operator can match the location indicator (20) corresponding to each spinal segment on the image with the number of the identification indicator (30). The operator can simultaneously verify a plurality of puncture locations within a single image. The operator can quickly calculate the puncture location corresponding to the target spinal segment based on the number of the identification indicator (30). For example, the operator can collectively identify each puncture location by verifying the identification numbers of the location indicator (20) corresponding to spinal segments L4, L5, and L6 on the image. The operator can determine all target puncture locations using only a single image without additional radiography. This process can directly contribute to shortening the procedure time and reducing radiation exposure.

[0063] In one embodiment, a surgical needle can be inserted into a guide portion of a position indicator corresponding to a calculated puncture position and advanced to a target depth. The operator can select a guide portion of a position indicator (20) corresponding to a calculated puncture position on an image. The operator can accurately insert the surgical needle into the selected guide portion. The guide portion is formed with a V-shaped or U-shaped groove structure to support the needle so that it does not slip. The operator can stably advance the needle to a target depth along the guide portion. The guide portion can be designed to maintain a constant insertion angle and path of the needle. During the needle insertion process, the guide portion acts as a physical support, thereby increasing the accuracy and safety of the procedure.

[0064] In one embodiment, the procedure guide indicator (1) is a device for guiding the puncture location of a target area during a procedure using radiation imaging equipment, and may provide a plurality of location indicators (20) and identification markers (30) in an integrated grid form. The procedure guide indicator (1) may form a visual coordinate system corresponding to anatomical structures by arranging the plurality of location indicators (20) and identification markers (30) at regular intervals. The location indicators (20) may be arranged along the central axis (10) to match the average spacing between vertebral segments. The identification markers (30) may be formed in the form of numbers, letters, or perforations corresponding to each location indicator (20). The integrated grid structure enables clear distinction of each puncture location on the radiation image. For example, the operator can identify multiple puncture locations at once by matching the number of the identification marker (30) with the vertebral segment on the image. Ref 7, Ref 8, Ref 12

[0065] In at least one embodiment of the present disclosure, a surgical guide indicator (1) may include a central axis portion (10), a handle portion (11), a position indicator portion (20), and an identification marker portion (30). The central axis portion (10) may be formed as a linear body extending in one direction. The central axis portion (10) may be made of a radiopaque material so that it is clearly visible in an image. The handle portion (11) may extend in a cross direction from the central axis portion (10) and provide a structure that allows the operator to grip it with their hand. The position indicator portion (20) may be spaced apart by a predetermined interval along the longitudinal direction of the central axis portion (10). The identification marker portion (30) may be formed in the form of a number, a letter, or a perforation corresponding to each position indicator portion (20). Ref 10, Ref 11, Ref 12

[0066] In at least one embodiment of the present disclosure, the surgical guide indicator (1) may function as a physical support that guides a surgical needle while providing a visual coordinate system on a radiographic image, with each component interconnected. The central axis portion (10), the handle portion (11), the position indicator portion (20), and the identification marker portion (30) may be integrally connected to ensure structural stability. The position indicator portion (20) and the identification marker portion (30) may overlap with anatomical structures on a radiographic image to form a visual coordinate system. A guide portion is formed at the end of the position indicator portion (20) to guide the surgical needle to be inserted along an accurate path without slipping. This combined structure allows the operator to quickly calculate multiple puncture locations in a single shot and simultaneously provide a physical support function during needle insertion. Ref 13, Ref 9

[0067] In at least one embodiment of the present disclosure, the surgical guide indicator (1) can collectively identify multiple puncture locations with only a single instrument placement and radiographic imaging. The operator may place the surgical guide indicator (1) on the site to be treated and then perform a single imaging using a radiographic imaging device (200). In the image obtained from a single imaging, a plurality of location indicators (20) and identification markers (30) are simultaneously projected, allowing multiple puncture locations to be collectively identified. For example, all puncture locations for vertebrae 4, 5, and 6 can be calculated in a single imaging. Ref 8, Ref 2, Ref 3

[0068] In at least one embodiment of the present disclosure, the procedure guide indicator (1) can solve the problem that in conventional X-ray-guided nerve block, the operator must repeatedly irradiate each individual puncture site. In the conventional method, separate radiography was required for each puncture site, but the procedure guide indicator (1) can eliminate the need for repeated imaging by identifying multiple puncture sites at once. This can significantly reduce the cumulative radiation exposure to the patient and medical staff. Ref 5, Ref 6

[0069] In one embodiment, the procedure guide indicator (1) can reduce the amount of radiation exposure to the patient and medical staff. A single-shot method can minimize the number of radiation exposures during the procedure. The handle portion (11) is extended to a sufficient length so that the operator's hand can be positioned outside the radiation exposure area. This structural design can reduce the risk of radiation exposure for both the patient and the medical staff. Ref 1

[0070] In at least one embodiment of the present disclosure, the surgical guide indicator (1) allows the identification marker (30) and the location indicator (20) to be intuitively identified on the image, thereby enabling the operator to quickly calculate the target puncture location. The identification marker (30) may be formed in the form of a number, a letter, or a perforation so that it can be clearly distinguished on the image. The operator can quickly identify the target puncture location by matching the identification number displayed on the image with the anatomical structure. For example, by identifying identification markers (30) 1, 4, and 8 on the image, the operator can quickly insert a needle into the corresponding location. Ref 2, Ref 3

[0071] In at least one embodiment of the present disclosure, the surgical guide indicator (1) can guide multiple puncture locations at once, thereby shortening the surgical time. The position indicator (20) is arranged in multiple numbers according to the average spacing between spinal segments, so that multiple puncture locations can be guided simultaneously. The operator can calculate multiple insertion points collectively after a single shot, thereby omitting the repetitive process of position verification and shooting. As a result, the total surgical time can be significantly shortened. Ref 2, Ref 3

[0072] In at least one embodiment of the present disclosure, the surgical guide indicator (1) can enhance the visibility and intuitiveness of the markings so that the operator can intuitively insert multiple points. The identification marker (30) may be displayed in bright contrast that contrasts with the surrounding metal parts on the radiographic image. The position indicator (20) and the identification marker (30) are clearly arranged on the image so that the operator can intuitively select the insertion location without separate calculations or additional markings. For example, the operator can sequentially insert multiple insertion points based only on the identification number on the image. Ref 2, Ref 3

[0073] In at least one embodiment of the present disclosure, the surgical guide indicator (1) can prevent slippage during needle insertion and maintain an accurate puncture path through a guide portion formed at the end of the position indicator portion (20). The guide portion may be formed in a V-shaped or U-shaped groove shape at the end of the position indicator portion (20). The surgical needle is seated in the guide portion and can enter along the target path without slippage during insertion. For example, the needle can be fixed in the groove of the guide portion so that it can be accurately inserted at the angle and position desired by the operator. Ref 9

[0074] In at least one embodiment of the present disclosure, the procedure guide indicator (1) may organically combine a visual guide function and a physical guide function to improve the accuracy and safety of the procedure. The position indicator (20) and the identification marker (30) provide a visual coordinate system in the image, enabling the operator to identify the accurate puncture location. The guide acts as a physical support during needle insertion, thereby stably maintaining the needle's entry path. This combination of visual and physical guide functions can reduce errors during the procedure and decrease the risk of complications. Ref 13, Ref 9

[0075] In at least one embodiment of the present disclosure, the embodiments of the present invention may be modified or extended in various forms. The embodiments of the present invention may be modified in various ways regarding the arrangement, shape, material, and method of joining of components. For example, the structural combination of the central axis portion (10), the handle portion (11), the position indicator portion (20), the identification marker portion (30), and the guide portion may be changed. Each component may be selectively combined according to the treatment environment, the preference of the operator, or the anatomical characteristics of the application site. The embodiments of the present invention are not limited to a single structure and may be implemented as a plurality of modified models. For example, the spacing of the position indicator portion (20), the method of joining the handle portion (11), the shape of the guide portion, etc., may be customized according to clinical requirements.

[0076] In at least one embodiment of the present disclosure, the structure and function of the surgical guide indicator (1) may be varied depending on the application area, the purpose of the procedure, and the usage environment. The surgical guide indicator (1) may have structural differences depending on the region of the spine, such as the lumbar spine, cervical spine, and thoracic spine. Depending on the purpose of the procedure, the number and spacing of the position indicator (20) and the method of displaying the identification marker (30) may vary. Depending on the usage environment, the type of radiopaque material, the length of the handle (11), and the groove depth of the guide may be adjusted. For example, in an environment where mobile radiation equipment is used, the overall length and weight of the indicator (1) may be reduced.

[0077] In at least one embodiment of the present disclosure, the spacing between the position indicators (20) may be provided in various models having different fixed spacings depending on the application area, such as the lumbar spine (L-spine) or cervical spine (C-spine). The spacing between the position indicators (20) may be designed to match the average segment spacing of the anatomical structure. For example, the position indicators (20) may be arranged at an average spacing of 35 mm in the lumbar spine (L-spine) application model and at an average spacing of 25 mm in the cervical spine (C-spine) application model. Each model reflects the difference in segment spacing for each spinal region, enabling the operator to calculate the accurate puncture location on the image. The spacing of the position indicators (20) may be standardized based on clinical data and may be produced as a customized model as needed.

[0078] In one embodiment, the handle portion (11) may be formed integrally with the central shaft portion (10), or modified to be rotatable or detachable through a hinge or coupling module. The handle portion (11) may be designed to allow angle adjustment with respect to the central shaft portion (10) by applying a hinge structure. The handle portion (11) may be separated from or reattached to the central shaft portion (10) using a coupling module. For example, the handle portion (11) may be detachable by screw coupling, slide coupling, or magnetic coupling. The rotational function of the handle portion (11) allows the placement direction of the indicator (1) to be adjusted according to the operator's gripping angle. The detachable handle portion (11) can increase space efficiency during storage and sterilization processes.

[0079] In one embodiment, the shape of the guide portion may be replaced with a semicircular groove, or a replaceable clip structure corresponding to the thickness of the needle, and the scope of the present invention is not limited to a specific structure or shape. The guide portion may be implemented in various shapes, such as a V-shape, a U-shape, or a flat groove. A detachable or slide-type clip structure may be applied so that the guide portion can be replaced according to the diameter of the needle. For example, the guide portion may include a rubber pad or an uneven structure on the inside to prevent slipping when inserting the needle. The replaceable guide portion may be applied to multiple treatment environments with a single indicator (1) in correspondence with various treatment needles. The clip-type guide portion may be designed to fix the needle while allowing for quick detachment and replacement when necessary.

[0081] FIG. 2c is another example of a surgical guide indicator according to one embodiment.

[0082] Referring to FIG. 2c, in at least one embodiment of the present disclosure, the surgical guide indicator (1) may further include a precision guide projection (21) at the end of the position indicator (20). The precision guide projection (21) may be composed of a plurality of projections formed by protruding outward from at least one end of the position indicator (20). The precision guide projection (21) may be arranged in a comb shape on both sides of the end of the position indicator (20). The precision guide projection (21) may serve to guide and fix the position of the needle more precisely when the surgical needle is inserted into the puncture position.

[0083] In one embodiment, the precision guide projection (21) may be symmetrically positioned on both ends of the position indicator (20). The precision guide projection (21) may protrude in a direction perpendicular to the longitudinal direction of the position indicator (20) to prevent the needle from deviating to the left or right when inserted. A plurality of projections constituting the precision guide projection (21) may be arranged at regular intervals, and this arrangement may be designed so that the needle can be seated between adjacent projections corresponding to the diameter of the needle. For example, the spacing between the plurality of projections corresponds to the diameter of the surgical needle, so that the needle can be physically fitted and fixed between the projections.

[0084] In one embodiment, the precision guide projection (21) can provide a more precise position alignment function compared to a conventional guide (V-shaped or U-shaped groove). Multiple projections of the precision guide projection (21) can simultaneously suppress axial and lateral shaking of the needle during the process of inserting the needle. The precision guide projection (21) can improve the precision of the puncture path by maintaining a constant insertion angle of the needle. The precision guide projection (21) is formed of a radiopaque material so that it can be clearly projected together with the position indicator (20) on the radiation image. Through this, the operator can check the position of the precision guide projection (21) on the image and calculate a more accurate puncture position.

[0085] In one embodiment, the precision guide projection (21) may be integrally molded with the position indicator (20) or manufactured as a separate component and coupled to the end of the position indicator (20). The height, spacing, and number of projections of the precision guide projection (21) may be designed to vary depending on the specifications of the surgical needle and the surgical environment. For example, the precision guide projection (21) may be provided with a structure in which the spacing of the projections gradually changes to accommodate multiple needles of different thicknesses. The precision guide projection (21) may be provided on both ends of the position indicator (20) or may be selectively provided on only one end.

[0087] FIG. 2d is another example of a surgical guide indicator according to one embodiment.

[0088] Referring to FIG. 2d, in at least one embodiment of the present disclosure, the surgical guide indicator (1) may include a precision guide projection (21) at the end of the position indicator (20), similar to the embodiment of FIG. 2c. In the embodiment of FIG. 2d, the precision guide projection (21) may be composed of a plurality of projections formed by protruding outward from at least one end of the position indicator (20), similar to the embodiment of FIG. 2c, and may be arranged in a comb shape on both sides of the end of the position indicator (20).

[0089] However, in the embodiment of FIG. 2c, the length of the precision guide projection (21) may differ from the length of the position indicator (20), whereas in the embodiment of FIG. 2d, the length of the precision guide projection (21) may be formed to be the same as the length of the position indicator (20). That is, the precision guide projection (21) according to the embodiment of FIG. 2d is extended to the same length as the position indicator (20), so that the projections can be uniformly arranged over the entire end of the position indicator (20).

[0090] In one embodiment, as shown in FIG. 2d, when the length of the precision guide projection (21) is formed to be the same as the length of the position indicator (20), the projection is arranged over the entire end section of the position indicator (20), so that the procedure needle can be guided and fixed by the projection even if it comes into contact with any point of the position indicator (20). Through this, the degree of freedom regarding the insertion position of the needle is increased, while effectively preventing the needle from deviating to the left or right.

[0091] On the other hand, as shown in FIG. 2c, if the length of the precision guide projection (21) is formed differently from the length of the position indicator (20), the projection may be arranged only in a portion of the end of the position indicator (20), so that the insertion position of the needle can be guided to a specific section where the projection is arranged. In this case, the puncture position intended by the operator can be specified more specifically, which may be advantageous in a surgical environment where precise position control is required.

[0092] In one embodiment, the precision guide projection (21) according to the embodiment of FIG. 2d may be integrally molded with the position indicator (20) as in the embodiment of FIG. 2c, or may be manufactured as a separate member and coupled to the end of the position indicator (20).

[0093] In one embodiment, the length of the position indicator (20) shown in FIG. 2c and FIG. 2d and the length of the plurality of protrusions constituting the precision guide protrusion (21) are not limited to the ratio and shape shown in each figure, and this is merely an exemplary representation of one embodiment. The length of the position indicator (20) and the length of the protrusions of the precision guide protrusion (21) can be implemented by varying them according to the anatomical characteristics of the area to be treated, the specifications of the needle used for treatment, the treatment environment, and the clinical purpose.

[0095] FIGS. 3a and FIGS. 3b are examples of radiation images according to one embodiment.

[0096] In one embodiment, the surgical guide indicator (1) may provide a plurality of position indicators and identification markers corresponding to anatomical structures in an integrated grid form. The surgical guide indicator (1) may have a plurality of position indicators (20) arranged at regular intervals along a central axis (10). An identification marker (30) may be placed correspondingly at each position indicator (20). The position indicators (20) and identification markers (30) may form a grid structure in an orthogonal or parallel arrangement. For example, the position indicators (20) may be designed to match the average spacing of the vertebrae, and the identification markers (30) may include numbers or letters to clearly distinguish each position. This grid structure may provide a coordinate system that corresponds to anatomical structures in a radiographic image. The operator can quickly identify the target puncture location by referring to the identification markers (30) within the image.

[0097] In at least one embodiment of the present disclosure, the operator can collectively identify multiple puncture locations with only a single instrument placement and radiographic imaging. The operator can place the guide indicator (1) for the procedure on the surface of the patient's skin by gripping the handle portion (11). The radiographic imaging device (200) can perform a single radiographic imaging with the indicator (1) placed. In the captured image, the location indicator (20) and the identification marker (30) can be projected simultaneously along with anatomical structures. The operator can calculate multiple puncture locations at once by identifying the identification marker (30) that corresponds to the target spinal segment on the image. For example, when performing a procedure on L-spine 4, 5, and 6, three points can be collectively identified by referring to identification markers (30) number 1, 4, and 8 of the indicator (1).

[0098] In one embodiment, the procedure guide indicator (1) can guide the puncture location of the target area during a procedure using a radiation imaging device. The procedure guide indicator (1) is used in conjunction with the radiation imaging device (200) to superimpose the anatomical structure of the target area and the location indicator (20) on the image. The operator can check how the location indicator (20) and the identification marker (30) are aligned with the anatomical structure through the image output on the display device (300). A guide portion is formed at the end of the location indicator (20) to guide the procedure needle to enter the correct puncture location. For example, the guide portion may be designed as a V-shaped or U-shaped groove to prevent the needle from slipping.

[0099] In at least one embodiment of the present disclosure, the principle of setting anatomical structure matching intervals and identifying multiple puncture locations based on radiographic images enables the rapid calculation of multiple puncture locations in a single radiographic image. The setting of anatomical structure matching intervals can be implemented by designing the interval between the position indicators (20) to match the average interval of the vertebral segments. The identification of multiple puncture locations based on radiographic images is based on the principle that the position indicators (20) and the identification markers (30) are projected simultaneously with anatomical structures in a single image. The operator can rapidly derive multiple puncture locations by matching each identification marker (30) with a vertebral segment within the image. For example, three or more puncture locations can be identified collectively in a single image.

[0100] In one embodiment, the spacing of the position indicators can be designed to correspond to the average spacing of anatomical structures such as spinal segments. Based on clinical data, the position indicators (20) can be arranged at different spacings depending on the region, such as an average of 35 mm in the lumbar spine (L-spine) and an average of 25 mm in the cervical spine (C-spine). The spacing of the position indicators (20) reflects the actual average spacing of anatomical structures, allowing the puncture location to be calculated without error in the image. For example, the lumbar spine procedure indicator (1) may have the position indicators (20) arranged at 35 mm intervals to provide a puncture location that exactly matches the lumbar segments.

[0101] In one embodiment, the principle can provide the effect of reducing the radiation exposure of the operator and shortening the procedure time. Since multiple puncture locations can be identified with only a single radiographic image, the cumulative radiation exposure of the operator and patient due to repeated imaging can be significantly reduced. Due to the intuitive arrangement of the location indicator (20) and the identification marker (30), the operator can shorten the time required for image interpretation and puncture location calculation. For example, compared to the conventional method, the number of radiation exposures can be reduced to one-third or less, and the procedure time can be shortened to minutes.

[0102] In one embodiment, the procedure guide indicator (1) may be designed to guide the puncture location based on the correlation between the anatomical structure, the vertebral segment, and the location indicator (20). The procedure guide indicator (1) may determine the spacing of the location indicator (20) based on the anatomical arrangement of the vertebral segment. The location indicator (20) may be arranged on the central axis (10) according to the average spacing of the vertebral segments. For example, the operator may quickly calculate the puncture location by directly comparing the location indicator (20) and the location of the vertebral segment on the radiographic image. The location indicator (20) is linked with an identification marker (30) to clearly distinguish each puncture location. This design allows multiple puncture locations to be identified collectively with only a single radiographic image.

[0103] In at least one embodiment of the present disclosure, one or more position indicators (20) may be arranged spaced apart by a predetermined interval along the longitudinal direction of the central axis (10). The position indicators (20) may be arranged in multiple numbers spaced apart by a certain distance along the longitudinal direction of the central axis (10). Each position indicator (20) may extend to the left or right or in one direction relative to the central axis (10). For example, the position indicators (20) may be formed in a cross-shaped or comb-shaped structure to provide clear coordinate axes on the radiation image. An identification marker (30) corresponds to each position indicator (20) so that each position can be distinguished.

[0104] In at least one embodiment of the present disclosure, the pre-set interval may be designed to correspond to the average interval between anatomical structures, for example, between vertebrae. The pre-set interval may be set to match the average distance between vertebrae calculated according to clinical data or anatomical standard data. For example, the position markers (20) may be arranged at intervals of about 35 mm for the lumbar (L-spine) segment and about 25 mm for the cervical (C-spine) segment. This spacing design ensures that the vertebrae and the position markers (20) align precisely on the radiographic image, thereby increasing the accuracy of the puncture location calculation.

[0105] In at least one embodiment of the present disclosure, a spinal segment is an anatomical structure constituting the spine of the human body and can be divided by region, such as the lumbar spine (L-spine) and cervical spine (C-spine). The spinal segment can be anatomically subdivided into the lumbar spine, cervical spine, thoracic spine, etc. Each spinal segment can be identified by distinct boundaries on a radiographic image. For example, the lumbar segments may be divided into 5 segments and the cervical segments into 7 segments and appear in the image. The location of the spinal segment can be directly matched with the position indicator (20) of the surgical guide indicator (1).

[0106] In one embodiment, one or more vertebral segments can be clearly identified on a radiographic image, and the location of each segment can be matched with the location indicator (20) of the procedure guide indicator (1). The radiographic imaging device (200) can clearly project the anatomical boundaries of the vertebral segments onto the image. The operator can identify the location of each vertebral segment within the image and select the location indicator (20) corresponding to that location. For example, the location indicator (20) corresponding to the L4, L5, and L6 segments can be referenced together with the identification marker (30) to determine the puncture location.

[0107] In at least one embodiment of the present disclosure, the average internode spacing may be calculated based on clinical data or anatomical standard data. The average internode spacing may be derived by statistically analyzing data from multiple patients. Anatomical standard data may provide average spacing values ​​for each vertebral region. For example, the average internode spacing of the lumbar region may be calculated as approximately 35 mm based on clinical study results.

[0108] In at least one embodiment of the present disclosure, for example, the average segment spacing of the lumbar (L-spine) segment can be derived to be about 35 mm, and the average segment spacing of the cervical (C-spine) segment can be derived to be about 25 mm. The average segment spacing of the lumbar (L-spine) segment can be set to 35 mm, and the average segment spacing of the cervical (C-spine) segment can be set to 25 mm. These values ​​can be determined based on anatomical studies and clinical experience. For example, the position indicators (20) for the lumbar procedure indicator (1) can be arranged at 35 mm intervals, and the indicators (1) for the cervical procedure can be arranged at 25 mm intervals.

[0109] In one embodiment, the derived average segment spacing can be directly reflected in the design of the spacing distance between the position indicators (20). The spacing distance between the position indicators (20) can be designed to be the same as the calculated average segment spacing. For example, the position indicators (20) for the lumbar spine (1) can be spaced at 35 mm intervals, and the position indicators (20) for the cervical spine (1) can be spaced at 25 mm intervals. This design ensures that the spinal segments and the position indicators (20) align exactly on the radiographic image.

[0110] In one embodiment, the spacing of the position indicators (20) may be designed to correspond to the average spacing of the derived vertebral segments. The position indicators (20) may be arranged at a distance equal to the average spacing of the vertebral segments. For example, the position indicators (20) may be designed at a spacing of 35 mm for the lumbar segments and 25 mm for the cervical segments. This spacing design can increase the accuracy of the puncture location calculation.

[0111] In at least one embodiment of the present disclosure, the position indicator (20) may be arranged at different intervals depending on the application site, such as the lumbar spine or cervical spine, and may be provided as various models having different fixation intervals for each site. The position indicator (20) may be manufactured as various interval models depending on the treatment site. For example, the lumbar spine indicator (1) may be provided as a model with a 35mm interval, and the cervical spine indicator (1) may be provided as a model with a 25mm interval. The user may select and use the indicator (1) suitable for the treatment site.

[0112] In at least one embodiment of the present disclosure, the spacing design of the position indicator (20) may be set as a reference to calculate a puncture location that exactly corresponds to a vertebral segment in a radiographic image. The spacing of the position indicator (20) is designed to be aligned with the vertebral segment in the radiographic image without error. For example, the operator may determine the puncture location based on the point where the position indicator (20) and the vertebral segment coincide within the image. Such a reference can increase the reliability of the puncture location calculation.

[0113] In one embodiment, the present invention relates to a surgical guide indicator for guiding the puncture location of a treatment site during a procedure using radiographic imaging equipment. The present invention can visually guide the puncture location based on image data acquired through radiographic imaging equipment. The surgical guide indicator is placed directly on the surface of the patient's skin and can be projected along with anatomical structures on the radiographic image. The surgical guide indicator can accurately specify the puncture location by aligning it with anatomical reference points, such as vertebral segments. For example, the operator can place the indicator in alignment with the direction of spinal alignment and then confirm the puncture location at a glance within the image through radiographic imaging.

[0114] In at least one embodiment of the present disclosure, the present invention is based on the concept of moving away from a single-point verification method and providing a plurality of indicator lines and identification markers corresponding to anatomical structures of the human body in an integrated grid form. The present invention can implement a grid-shaped coordinate system corresponding to anatomical structures on an image by arranging a plurality of position indicators and identification markers at regular intervals. The position indicators are designed to match the average spacing between vertebral segments so that each position indicator can be directly matched to an anatomical reference point. Identification markers are assigned corresponding to each position indicator, enabling the operator to clearly distinguish each puncture location within the image. For example, position indicators arranged in a cross or comb shape and identification markers displaying numbers or letters are combined to allow simultaneous verification of multiple puncture locations on the image.

[0115] In at least one embodiment of the present disclosure, the operator can collectively identify multiple puncture locations with only a single instrument placement and radiographic imaging. The operator may place a procedure guide indicator on the patient's skin surface once and then perform a single imaging using a radiographic imaging device. In the image obtained from the single imaging, a plurality of location indicators and identification markers are projected and displayed together with anatomical structures. The operator can collectively calculate multiple puncture locations corresponding to the target lesion within the image by matching them with the numbers of the identification markers. For example, by checking the identification numbers of the location indicators corresponding to L4, L5, and L6 at once, each puncture location can be designated without repeated imaging.

[0116] In at least one embodiment of the present disclosure, a surgical guide indicator may include a central axis portion, a handle portion, a position indicator portion, and an identification marker portion. The surgical guide indicator may be arranged such that a plurality of position indicator portions intersect along the central axis portion. An identification marker portion for distinguishing each position indicator portion may be positioned in correspondence with it. A handle portion that can be grasped by a surgeon may be extended and disposed on one side of the central axis portion. For example, the central axis portion may be formed of a radiopaque material so as to be clearly visible in an image, and the handle portion may be designed to have a sufficient length so that the surgeon's hand is positioned outside the radiation irradiation area.

[0117] In at least one embodiment of the present disclosure, an identification marker for distinguishing each point of a position indicator may be positioned in correspondence with it. Each position indicator is matched one-to-one with a unique identification marker, so that each puncture location can be clearly distinguished in the image. The identification marker is positioned at the center or end of the position indicator so that it can be visually distinguished within the radiographic image. For example, when the position indicators are arranged according to the average spacing between vertebral segments, each identification marker may be directly matched with the corresponding vertebral segment.

[0118] In at least one embodiment of the present disclosure, the identification marker may include at least one of a number, a letter, or a figure. The identification marker may be composed of an Arabic numeral, a Latin letter (e.g., A, B, C, etc.), an alphabet letter, or a figure such as a circle or a triangle. Each identification marker is displayed with a different symbol for each location indicator, so that the operator can identify each location within the image without confusion. For example, consecutive Arabic numerals such as 1, 2, and 3 may be assigned to each location indicator. When Arabic numerals are adopted in this manner, the operator can intuitively recognize the corresponding location at a glance solely by the number indicated on each location indicator, without needing to count sequentially to determine which position among multiple location indicators corresponds to the top. This can significantly improve the speed and accuracy of location identification, particularly in a surgical environment where multiple puncture locations must be identified collectively.

[0119] In at least one embodiment of the present disclosure, the identification marker may be formed in the form of a perforation penetrating a portion of the material of the central axis portion or the position indicator portion, and configured to be distinguished by bright contrast in the image when radiation passes through. The identification marker may be implemented by forming a circular or square perforation in the central axis portion or the position indicator portion. When radiation passes through, the perforated identification marker is displayed as a bright dot or line in the image, creating a clear contrast with the dark parts of the metal material. For example, since the metal part appears dark and the perforation part appears bright in the image, the operator can easily recognize each identification marker.

[0120] In at least one embodiment of the present disclosure, the operator can determine the puncture location by matching a vertebral segment with an identification marker on a radiographic image. The operator can rapidly calculate the target puncture location by comparing the anatomical boundary of the vertebral segment with the location of the identification marker within the image. For example, after confirming the identification marker numbers corresponding to vertebral segments L4, L5, and L6 in the image, the operator can insert a puncture needle at the corresponding location. This matching process can be performed with a single image without repeated shooting.

[0121] In one embodiment, one or more position indicators may be arranged spaced apart by a predetermined interval along the longitudinal direction of the central axis. Multiple position indicators may be arranged spaced apart by a certain distance along the longitudinal direction of the central axis. Each position indicator may be designed to match the average spacing of anatomical structures and placed at a position corresponding to a vertebral segment. For example, in the case of the lumbar segment, position indicators may be arranged at intervals of approximately 35 mm.

[0122] In at least one embodiment of the present disclosure, the position indicator may be composed of a linear member that extends in both directions relative to the central axis to form a cross shape, or extends in only one direction to form a comb shape. The position indicator may extend to both the left and right sides of the central axis to form a cross-shaped structure. Alternatively, the position indicator may extend in only one direction relative to the central axis to implement a comb-shaped structure. For example, the cross-shaped structure is displayed in the form of a coordinate axis on an image, allowing the operator to intuitively identify the puncture location.

[0123] In at least one embodiment of the present disclosure, the operator can collectively calculate puncture locations by verifying the identification number of a location marker that corresponds to a target lesion on the image data. The operator can verify the identification number of a location marker that is aligned with the vertebral segment where the target lesion is located within the image. Since multiple location markers and identification markers are displayed simultaneously, the operator can calculate multiple puncture locations at once. For example, by selecting location markers 1, 4, and 8 corresponding to L4, L5, and L6, the operator can collectively designate each puncture location.

[0124] In one embodiment, a plurality of location indicators and identification markers may provide clear contrast and arrangement so that they can be intuitively recognized on a radiographic image. The location indicators and identification markers may form a clear visual contrast within the radiographic image through a combination of dark metallic parts and bright perforations. The arrangement is composed of regular intervals and a regular pattern, allowing the operator to quickly recognize each location within the image. For example, the identification markers may be arranged as consecutive numbers or shapes, allowing the operator to identify each puncture location without confusion.

[0125] In at least one embodiment of the present disclosure, a practitioner may grasp a handle and primarily position a guide indicator for the procedure on the surface of a target area. The practitioner may grasp the handle and position the indicator on the skin surface so that its central axis is parallel to the direction of spinal alignment. The handle may be designed to be of sufficient length so that the practitioner's hand is positioned outside the radiation irradiation area. For example, the practitioner may position the indicator precisely on the patient's lumbar or cervical spine.

[0126] In one embodiment, image data in which a position indicator and an identification marker are projected along with anatomical structures can be generated by performing a single shot using radiation equipment. The radiation imaging equipment can acquire an image in which internal anatomical structures and the position indicator and identification marker of the indicator are simultaneously projected by irradiating radiation onto a site where an indicator is mounted. The acquired image can be displayed in real time on a display device. For example, in the image, the vertebral segment and each position indicator and identification marker are clearly displayed on the same plane.

[0127] In one embodiment, the operator can collectively calculate and identify individual puncture locations corresponding to multiple spinal segments by matching them with identification numbers based on a single image output to a display device. The operator can quickly calculate each puncture location by checking the number of an identification marker located on the same line as the target spinal segment within the image. Since multiple puncture locations are displayed at once, the operator can collectively identify all target locations without repeated imaging. For example, after confirming the identification numbers corresponding to L4, L5, and L6 in the image, the operator can prepare to insert a needle at each location.

[0128] In at least one embodiment of the present disclosure, a surgical needle can be inserted to a target depth by placing it on a guide portion of a position indicator corresponding to a calculated puncture position. The operator may place the surgical needle on a guide portion provided at the end of the position indicator corresponding to the calculated puncture position. The guide portion is formed with a V-shaped or U-shaped groove to support the needle so that it can enter along an accurate path without slipping. For example, after placing the needle on the guide portion, the operator may complete the procedure by slowly inserting the needle to a target depth.

[0129] In at least one embodiment of the present disclosure, the exemplary image description may explain specific examples of how a surgical guide indicator is projected within an image acquired through radiographic imaging equipment and how it is displayed in relation to anatomical structures. The exemplary image description may explain step-by-step how the central axis, position indicator, and identification marker of the surgical guide indicator are arranged and contrasted with anatomical structures within the radiographic image. The exemplary image description may specifically present the process by which each component is clearly identified in an actual projected image acquired using radiographic imaging equipment. The exemplary image description may include a procedure in which the operator visually confirms the interrelationship between the vertebral segment, the position indicator, and the identification marker within the image. The exemplary image description may explain actual clinical application cases in which multiple puncture locations are identified collectively with a single shot. The exemplary image description may specifically diagram how each position indicator and identification marker is matched with anatomical reference points on the radiographic image.

[0130] In one embodiment, the example image description may include the projection characteristics of the indicator, the contrast between the position indicator and the vertebral segment, and the visual recognition process of the identification marker at two representative shooting angles: oblique projection and frontal projection. The oblique projection image description may be explained based on the projection image obtained by irradiating the radiographic imaging equipment at an oblique angle while the indicator is positioned on the skin surface aligned with the direction of spinal alignment. The frontal projection image description may be explained based on the projection image obtained by irradiating the radiographic imaging equipment at a frontal angle while the indicator is positioned parallel to the direction of spinal alignment. For each shooting angle, the central axis, the position indicator, and the identification marker may be explained step-by-step as to how they overlap or are distinguished from anatomical structures within the image. For example, in the oblique projection, the position indicator and the vertebral segment may be projected in a form where they intersect obliquely, while in the frontal projection, the position indicator and the vertebral segment are aligned parallel to confirm consistency. The visual recognition process of the identification marker may be explained specifically through examples where numbers, letters, or shapes are clearly distinguishable within the image.

[0131] In one embodiment, an example of an oblique fluoroscopic image can be described based on a projected image obtained by irradiating a radiographic imaging device at an oblique angle while the indicator is positioned on the skin surface aligned with the direction of the patient's spinal alignment. An example of an oblique fluoroscopic image may be a situation in which the radiographic imaging device is irradiated at an oblique angle of 30 to 45 degrees while the central axis of the indicator is aligned parallel to the longitudinal direction of the spine. An example of an oblique fluoroscopic image can be described step-by-step in which the indicator is in close contact with the skin surface and the position indicator and identification marker are projected on the same plane as the anatomical structures. For example, in the oblique fluoroscopic image, the spinal segments and the position indicators may be displayed within the image in a form that intersects obliquely. An example of an oblique fluoroscopic image may include a procedure in which the operator intuitively confirms the relative positions of each position indicator and the spinal segment within the image.

[0132] In one embodiment, in an oblique projection image, the central axis portion, position indicator portion, and identification marker portion of the indicator may be projected and displayed on the same plane as the anatomical structure. The central axis portion may be formed of a radiopaque material and displayed as a clear straight line within the image. The position indicator portion may be arranged in a direction intersecting along the central axis portion and projected as a linear structure intersecting the vertebral segments within the image. The identification marker portion may be displayed within the image in the form of numbers, letters, or shapes corresponding to each position indicator portion. For example, if the identification marker portion is formed in a perforated shape, it may be distinguished within the image by bright contrast that contrasts with the surrounding metal parts upon radiographic transmission.

[0133] In one embodiment, the position indicators are arranged in a direction intersecting along the central axis so that they can be projected with clear contrast on the radiographic image. The position indicators are formed of a radiopaque material such as a radiopaque metal, a radiopaque alloy, or a barium-containing synthetic resin, so as to provide clear contrast with anatomical structures within the image. The position indicators are arranged in a cross shape or a comb shape to form multiple linear patterns that intersect with the vertebral segments within the image. For example, when the position indicators are arranged to match the average spacing between vertebral segments, each position indicator can be clearly displayed at a position corresponding to a vertebral segment within the image.

[0134] In at least one embodiment of the present disclosure, the position indicators are designed to match the average interval between vertebral segments and can be displayed at intervals that correspond to anatomical structures within the image. The intervals of the position indicators can be pre-set according to anatomical data for each application area, such as the lumbar spine or cervical spine. The position indicators can be arranged at regular intervals along the longitudinal direction of the central axis. For example, if the average interval between segments in the lumbar region is 15 mm, the position indicators can be arranged at 15 mm intervals to directly match the vertebral segments within the image.

[0135] In one embodiment, the location markers and the vertebral segments are clearly contrasted with each other in the radiographic image, allowing the operator to intuitively identify the puncture location corresponding to each vertebral segment. Within the radiographic image, the location markers are projected in a form that intersects the vertebral segments, which are anatomical structures, so that it is visually possible to verify whether each location marker coincides with the boundary or center of the vertebral segment. The operator can quickly calculate the target puncture location by comparing the relative positions of the location markers and the vertebral segments within the image. For example, the identification numbers of the location markers corresponding to vertebral segments L4, L5, and L6 can be identified at a glance within the image.

[0136] In at least one embodiment of the present disclosure, the spacing of the position markers is designed to correspond to the average spacing between vertebral segments, so that each position marker within the image can be directly matched to an anatomical reference point. Since the spacing of the position markers is designed based on anatomical data, each position marker within the image can accurately align with the boundary or center of a vertebral segment. The operator can identify multiple puncture locations collectively without repetitive radiography by verifying the alignment of the position markers with the vertebral segments within the image. For example, each puncture location can be designated without repetitive radiography by verifying the identification numbers of the position markers corresponding to L4, L5, and L6 in a single shot.

[0137] In at least one embodiment of the present disclosure, an example of a frontal projection image can be described based on a projected image obtained by irradiating a radiographic imaging device at a frontal angle while the indicator is positioned parallel to the direction of spinal alignment. An example of a frontal projection image may be a situation in which the radiographic imaging device is irradiated at a 0-degree angle while the central axis of the indicator is aligned completely parallel to the longitudinal direction of the spine. An example of a frontal projection image can be described step-by-step in which the indicator is in close contact with the surface of the skin and the position indicator and the identification marker are aligned in alignment with the spinal segment. For example, in the frontal projection image, the position indicator and the spinal segment are aligned parallel to each other, so that each position indicator can be linearly displayed at a position corresponding to the spinal segment.

[0138] In at least one embodiment of the present disclosure, in a frontal view image, a position indicator and an identification marker may be linearly arranged and displayed at positions corresponding to the vertebral segments. The position indicators may be arranged at regular intervals along a central axis and displayed on the same line as the vertebral segments within the image. The identification markers are assigned corresponding to each position indicator so that each puncture location can be clearly distinguished within the image. For example, in a frontal view image, the position indicator and the identification marker are arranged at positions that exactly correspond to the vertebral segments, allowing the operator to intuitively verify each puncture location.

[0139] In at least one embodiment of the present disclosure, each position indicator is arranged in a position corresponding to a vertebral segment in a frontal view image, so that the spacing and alignment between the indicators can be visually verified. The operator can directly check whether the spacing of the position indicators and the spacing between the vertebral segments match within the frontal view image. The operator can verify the placement accuracy of the indicators by comparing the alignment of the position indicators and the vertebral segments within the image. For example, if the position indicators exactly align with the center or boundary of a vertebral segment, the operator can ensure the reliability of the puncture location.

[0140] In one embodiment, an identification marker is assigned in correspondence with each location indicator so that each puncture location can be clearly distinguished within the image. The identification marker may be assigned in the form of a number, letter, or shape in a 1:1 correspondence with each location indicator. The identification marker may be displayed with bright contrast that contrasts with the surrounding metal parts within the image upon radiation transmission. For example, if the identification marker is formed in the form of a perforation, each puncture location can be clearly distinguished within the image.

[0141] In one embodiment, the identification marker is formed in the form of a perforation that penetrates a portion of the material of the central axis or the position indicator, so that it can be distinguished by a bright contrast in the image when radiation is transmitted. The perforation structure of the identification marker forms an opening through which radiation can pass, so that it can be displayed as a bright dot or line within the image. The identification marker provides a bright contrast in the image, allowing the operator to quickly identify each puncture location. For example, if the identification marker is perforated in the form of a number or a letter, the corresponding number or letter can be clearly distinguished within the image.

[0142] In one embodiment, the user can intuitively recognize each puncture location within the image through numbers, letters, or shapes on the identification marker. The user can quickly identify the target puncture location by checking the numbers, letters, or shapes displayed on the identification marker within the image. The visual readability of the identification marker can contribute to clearly distinguishing each puncture location within the image. For example, the user can identify identification numbers corresponding to L4, L5, and L6 at a glance within the image, thereby identifying multiple puncture locations collectively without repetitive radiography.

[0144] Although the embodiments have been described above with reference to the limited drawings, those skilled in the art can apply various technical modifications and variations based thereon. For example, suitable results may be achieved even if the described techniques are performed in a different order than described, and / or if the components of the described system, structure, device, circuit, etc. are combined or assembled in a form different from described, or replaced or substituted by other components or equivalents.

[0145] Therefore, other implementations, other embodiments, and equivalents to the claims also fall within the scope of the claims set forth below.
