[0010] An example of the present disclosure will be described below with reference to the accompanying drawings. The following description is merely exemplary in nature and does not limit the present disclosure, its applications, or uses. The accompanying drawings are schematic drawings, and the illustrated configurations and actual products may differ in dimensional ratios, etc. In the following description, terms such as "about" or "approximately" mean that the values, shapes, etc. following these terms include an acceptable range of error as determined by a person skilled in the art.

[0011] As shown in FIG. 1 , a puncture needle device 1 according to one aspect of the present disclosure includes a puncture needle 10 and a light irradiation device 20 .

[0012] In this embodiment, the needle 10 includes a linearly extending needle tube 11 and a needle base 12 connected to one end of the needle tube 11 in the direction in which the needle tube 11 extends. The other end of the needle tube 11, located on the opposite side of the needle base 12 in the direction in which the needle tube 11 extends, forms a needle tip 13. A syringe (not shown) is connected to the needle base 12. As an example, the light irradiation device 20 is connected to the needle base 12, but it may also be connected to a syringe connected to the needle base 12, for example.

[0013] The light irradiation device 20 includes a light source 21 and a connecting member 22 .

[0014] Light source 21 is configured to be able to emit light so that a line of light L (see FIG. 2) is marked on the puncture target. Examples of the puncture target include humans and animals. Light source 21 includes, for example, an LED element or a laser element. If light source 21 includes an LED element, light source 21 can mark the line of light on the puncture target by, for example, further including a lens that focuses the light emitted from the LED element. If light source 21 includes a laser element, light source 21 can mark the line of light on the puncture target by, for example, further including an optical lens that can project the laser light emitted from the laser element as a line. Light source 21 may include a cord for connection to an external power source (not shown) or an internal power source such as a battery.

[0015] The connecting member 22 is configured to be able to connect the light source 21 directly or indirectly to the puncture needle 10. A mode in which the light source 21 is directly connected to the needle 10 includes, for example, a mode in which the light source 21 is connected to the needle base 12. A mode in which the light source 21 is indirectly connected to the needle 10 includes, for example, a mode in which the light source 21 is connected to a syringe.

[0016] 2 , the connecting member 22 is configured to connect the light source 21 to the needle 10 so that the line of light L indicated by the light emitted from the light source 21 connected to the needle 10 overlaps with the needle 10 (in this embodiment, the needle tube portion 11). In other words, the light source 21 is connected to the needle 10 by the connecting member 22 so that the line of light L overlaps with the needle 10 (in this embodiment, the needle tube portion 11). "The line of light L overlaps with the needle tube portion 11" means, for example, that the entire needle tube portion 11 overlaps with the line of light L when viewed in the direction in which the light source 21 is connected to the needle base 12 (for example, the up-and-down direction in FIG. 1 ).

[0017] 3 and 4 show examples of usage of the puncture needle device 1. FIG. 3 shows an example of puncture using the cross method, and FIG. 4 shows an example of puncture using the parallel method. In FIGS. 3 and 4, a line of light L from the light irradiation device 20 is marked on the puncture target 40 while the puncture position is confirmed with a probe (an example of an ultrasound device) 30. The probe 30 has a longitudinal surface 31 and a lateral surface 32 that intersects with the longitudinal surface 31. In FIG. 3, the puncture needle device 1 is positioned relative to the puncture target 40 so that the line of light L is marked at the center P1 of the longitudinal surface 31 of the probe 30. In FIG. 4, the puncture needle device 1 is positioned relative to the puncture target 40 so that the line of light L is marked at the center P2 of the lateral surface 32 of the probe 30.

[0018] The light irradiation device 20 can achieve the following effects.

[0019] The light irradiation device 20 includes a light source 21 capable of irradiating light so that a line of light is marked on the puncture target, and a connecting member 22 capable of directly or indirectly connecting the light source 21 to the puncture needle 10. The connecting member 22 is configured to connect the light source 21 to the needle 10 so that the line of light L marked by the light emitted from the light source 21 connected to the needle 10 overlaps with the needle 10. With the light irradiation device 20 configured as described above, the line of light L allows the operator to easily grasp, for example, the positional relationship between the puncture direction and the probe, thereby assisting the operator in puncturing in the intended direction. Furthermore, not only the operator but also a person other than the operator (e.g., an instructor) positioned next to the operator can easily grasp the positional relationship between the puncture direction and the probe. As a result, a light irradiation device 20 capable of performing puncture accurately and quickly can be realized.

[0020] The needle 10 includes a needle tube portion 11 that extends linearly and a needle base portion 12 that is connected to one end of the needle tube portion 11 in the direction of extension of the needle tube portion 11. The connecting member 22 is configured to be able to connect the light source 21 to the needle 10 so that the linear light L overlaps the needle tube portion 11. This configuration more reliably realizes a light irradiation device 20 that can perform punctures accurately and quickly.

[0021] The puncture needle device 1 can achieve the following effects.

[0022] The puncture needle device 1 includes a puncture needle 10, a light source 21 capable of irradiating light so that a line of light L is marked on the target to be punctured, and a connecting member 22 connecting the light source 21 to the needle 10. The light source 21 is connected to the needle 10 so that the line of light L marked by the light emitted from the light source 21 overlaps with the needle 10. In the puncture needle device 1 configured as described above, the line of light L makes it easy to grasp, for example, the positional relationship between the puncture direction and the probe, thereby assisting the practitioner in puncturing in the intended direction. Furthermore, not only the practitioner but also a person other than the practitioner (e.g., an instructor) positioned next to the practitioner can easily grasp the positional relationship between the puncture direction and the probe. As a result, a puncture needle device 1 capable of performing puncture accurately and quickly can be realized.

[0023] The needle 10 includes a needle tube portion 11 that extends linearly and a needle base portion 12 that is connected to one end of the needle tube portion 11 in the direction of extension of the needle tube portion 11. A light source 21 is connected to the needle 10 so that the linear light L overlaps with the needle tube portion 11. This configuration more reliably realizes a light irradiation device 20 that can perform puncture accurately and quickly.

[0024] The light source 21 is located at the needle base 12. With this configuration, the linear light L makes it possible to more accurately grasp, for example, the positional relationship between the puncture direction and the probe.

[0025] The light irradiation device 20 and the puncture needle device 1 can be configured as follows.

[0026] The light irradiation device 20 may be detachably connected to the needle 10, or may be non-detachably connected to the needle 10. Figures 5 to 7 show an example of a light irradiation device 20 configured to be detachably connected to the needle 10.

[0027] In the light irradiation device 20 shown in Figure 5, the connecting member 22 is configured to be able to clamp the light source 21 together with the needle hub 12. The connecting member 22 has a first clip member 221, a second clip member 222 facing the first clip member 221, and a third clip member 223 connecting one end of the first clip member 221 and the second clip member 222. The tips of the first clip member 221 and the second clip member 222 are biased toward each other. The first clip member 221 and the second clip member 222 are each fitted with a handle 224 extending from the tip of the first clip member 221 and the second clip member 222 toward the third clip member 223. A space capable of accommodating the light source 21 and the needle hub 12 is provided between the first clip member 221 and the second clip member 222.

[0028] In the light irradiation device 20 shown in FIG. 6 , the connecting member 22 includes a clamping portion 23 configured to clamp the needle base 12 and a fixing portion 24 that fixes the light source 21 to the clamping portion 23. The clamping portion 23 has the same structure as the connecting member 22 in FIG. 5 . The fixing portion 24 is located on a third clip member 223. The fixing portion 24 has any configuration that can fix the light source 21 to the clamping portion 23. For example, the fixing portion 24 may include a permanent magnet, an adhesive, or a fastening member. When the fixing portion 24 includes a permanent magnet, the light source 21 is configured to be attracted to the permanent magnet of the fixing portion 24. In this way, various methods can be used to form the light irradiation device 20, making it possible to more reliably realize a light irradiation device 20 that can perform puncture accurately and quickly.

[0029] In the light irradiation device 20 shown in Fig. 7, the connecting member 22 includes an adjustment unit 25 that can adjust the direction of light emitted from the light source 21 with respect to the needle 10 while the light source 21 is connected to the needle 10. The connecting member 22 further includes a clamping unit 23, for example. The adjustment unit 25 is located on a third clip member 223 of the clamping unit 23. The light source 21 is connected to the clamping unit 23 via the adjustment unit 25. The adjustment unit 25 includes, for example, a hinge or a rotating disk that can hold any angle.

[0030] 5 to 7, any configuration that can directly or indirectly connect the light source 21 to the needle 10 can be adopted. For example, the connecting member 22 may be configured to be insertable into the needle base 12 or a syringe connected to the needle base 12 (hereinafter referred to as the needle base 12 or the syringe), or may be configured to be adhesively attached to the needle base 12 or the syringe. The connecting member 22 may be configured to form a single member together with the needle base 12 or the syringe.

[0031] In this way, various methods can be used to form the light irradiation device 20, so that the light irradiation device 20 that can perform puncturing accurately and quickly can be more reliably realized.

[0032] The puncture needle is not limited to the needle 10 including the needle tube portion 11 and the needle base portion 12, but may be a needle of another configuration.

[0042] The following examples are provided, but are not intended to limit the present disclosure.

[0043] Using the probe 30, five Japanese Board Certified Anesthesiologists (with 7 to 20 years of medical experience) examined the accuracy of puncture and the time required for puncture with and without the light irradiation device 20. The probe 30 was placed against an echo phantom on the target 40, and the needle 10 was advanced by the crossover method from a position 5 cm or more away from the probe 30, aiming toward the center line CL (see FIG. 3) of the probe 30. The center line CL is assumed to be, for example, a virtual straight line extending vertically in FIG. 3, passing through the center P1 (see FIG. 3) of the longitudinal surface 31 of the probe 30 and the center P2 (see FIG. 4) of the lateral surface 32.

[0044] Details of the needle 10, light irradiation device 20, probe 30, and puncture target 40 used in this example are as follows: Needle 10: Nerve block needle MM [20G x 140 mm], manufactured by Okayama Hakko Shoji Light irradiation device 20: Light irradiation device 20 shown in Figure 5 (light source 21: small laser light source (red) line 670 nm, manufactured by AS ONE Corporation) Probe 30: SonoSite SII, linear probe [6-13 MHz], manufactured by Fujifilm Corporation Puncture target 40: Echo phantom (CAE blue phantom) TM Ultrasound Training Models, manufactured by CAE healthcare Inc.)

[0045] FIG. 8 shows the distance of the needle 10 from the center line CL when the light irradiation device 20 was used and when the light irradiation device 20 was not used. In FIG. 8, the case where the light irradiation device 20 was used is indicated by "with device," and the case where the light irradiation device 20 was not used is indicated by "without device." As shown in FIG. 8, when the light irradiation device 20 was not used during puncture, the needle 10 was located an average of 0.33 cm away from the center line CL. On the other hand, when the light irradiation device 20 was used during puncture, the needle 10 was located an average of 0.08 cm away from the center line CL. In other words, using the light irradiation device 20 improved the accuracy of the puncture position by 83.6% compared to when the light irradiation device 20 was not used.

[0046] FIG. 9 shows the puncture time measured when the light irradiation device 20 was used and when the light irradiation device 20 was not used. The time required for the needle 10 to reach the puncture position was measured as the "puncture time." Whether the needle 10 reached the puncture position was determined, for example, by whether the probe 30 visualized the long axis of the needle 10. In FIG. 9, the case where the light irradiation device 20 was used is indicated by "with device," and the case where the light irradiation device 20 was not used is indicated by "without device." As shown in FIG. 9, when the light irradiation device 20 was not used, it took an average of 7.9 seconds for the needle 10 to reach the puncture position. On the other hand, when the light irradiation device 20 was used, it took an average of 3.1 seconds for the needle 10 to reach the puncture position. In other words, using the light irradiation device 20 reduced the time required for the needle 10 to reach the puncture position by 58.7% compared to when the light irradiation device 20 was not used.

[0047] The examples show that the use of the light irradiation device 20 enables accurate and rapid puncture.
