一种即插即用的医用光针A plug-and-play medical light needle

技术领域technical field

本发明涉及医疗器械领域，具体是利用光纤技术向体内注入光能量的、可用于诊断、针灸和治疗的一种即插即用的医用光针。The invention relates to the field of medical devices, in particular to a plug-and-play medical optical needle which uses optical fiber technology to inject light energy into the body and can be used for diagnosis, acupuncture and treatment.

背景技术Background technique

激光本身是一种能量，而且相干性、方向性很好，强度可以很高，输出波长和能量精密可控。例如，利用氩离子激光照射经体外循环的血液，可以杀死艾滋病毒；激光光谱的特征谱线可以用于诊断和判断药物的治疗效果。所以，激光不但可以用于治疗，还可以用于诊断。目前，激光已经用于皮肤病的治疗，或近表面的医学应用，例如在眼科和口腔科，已经相当普及。但是激光进入人体却很困难，这是因为人体的器官和组织对光不透明，光很难进入体内。The laser itself is a kind of energy, and the coherence and directionality are very good, the intensity can be very high, and the output wavelength and energy are precisely controllable. For example, the use of argon ion laser to irradiate blood through extracorporeal circulation can kill HIV; the characteristic lines of the laser spectrum can be used for diagnosis and to judge the therapeutic effect of drugs. Therefore, laser can be used not only for treatment, but also for diagnosis. Currently, lasers are already widely used in the treatment of skin diseases, or in near-surface medical applications, such as in ophthalmology and dentistry. However, it is very difficult for laser light to enter the human body. This is because the organs and tissues of the human body are opaque to light, and it is difficult for light to enter the body.

最早开发的将光引入体内的是由光纤束制成的内窥镜。现在，这种内窥镜的体探头可以做到直径仅1毫米，光纤像素达1万，分辨率几十微米，主要还是用于病变部位的诊断。新近发展的带有摄像机的胶囊型内窥镜做得很小(φ0.9×2.3cm)，也仅能用于诊断，而且很贵。弱激光照射用于治疗研究很多，很有发展潜力。用于体内治疗的，首先是激光针灸。最早开发出来的是半导体激光针灸器和氦氖激光针灸仪。这在上世纪末已经有相应的器械出售，但是疗效不理想。例如，原长春光机学院研发的半导体激光针灸器一套三件：带准直器外形如笔的半导体激光器，一个荧光池可以检测光输出状况以及一个电源。这种激光针灸的主要优点是不用针刺入皮肤，因而无感染的担心，也不会有刺痛的担心。但是没有发展起来，原因有两个，一是人体组织的散射和吸收使得进入体内的光很弱，也很难聚焦。二是选择透光比较好的波长，也会因吸收很少而热效应不佳，达不到针灸的目的。氦氖激光具有活血化瘀的功效。仔细研究其机制发现是血红细胞的变形能力增加了。用于血管内照射也已经有仪器了。1984年开始的低强度激光血管内照射得到了成功的应用。中国科学院安徽光机所开发的型号为YNH0-A型的氦氖激光血管内照射仪在肢体内闭塞性血管病治疗中应用取得好的结果。但是光纤进入体内的方法依然是一个问题，光纤的插入和固定都不容易，难于广泛使用和推广。The first developed to introduce light into the body were endoscopes made of bundles of optical fibers. Now, the body probe of this kind of endoscope can have a diameter of only 1 mm, an optical fiber pixel of 10,000, and a resolution of tens of microns. It is mainly used for the diagnosis of lesion. The newly developed capsule endoscope with camera is made very small (φ0.9×2.3cm), can only be used for diagnosis, and is very expensive. Weak laser irradiation has been used in many therapeutic researches and has great potential for development. For internal treatment, the first is laser acupuncture. The earliest developed are semiconductor laser acupuncture devices and helium-neon laser acupuncture devices. At the end of last century, there were corresponding devices for sale, but the curative effect was not satisfactory. For example, the semiconductor laser acupuncture device developed by the former Changchun Institute of Optics and Mechanics is a set of three pieces: a semiconductor laser with a collimator shaped like a pen, a fluorescent cell that can detect the light output status, and a power supply. The main advantage of this type of laser acupuncture is that it does not need to penetrate the skin with needles, so there is no worry of infection and no worry of stinging. But it has not been developed. There are two reasons. One is that the scattering and absorption of human tissue make the light entering the body very weak and difficult to focus. The second is to choose a wavelength with better light transmission, which will also cause poor thermal effect due to little absorption, and the purpose of acupuncture and moxibustion cannot be achieved. He-Ne laser has the effect of promoting blood circulation and removing blood stasis. Careful study of its mechanism found that the deformability of red blood cells increased. Instruments are also available for intravascular irradiation. Low-intensity laser intravascular irradiation started in 1984 has been successfully applied. The model YNH0-A helium-neon laser intravascular irradiation instrument developed by Anhui Institute of Optics and Mechanics, Chinese Academy of Sciences has achieved good results in the treatment of occlusive vascular diseases in extremities. However, the method for the optical fiber to enter the body is still a problem. The insertion and fixation of the optical fiber are not easy, and it is difficult to be widely used and promoted.

为了使光能通过光纤进入体内，实用新型专利CN00205098.6“一种激光针灸针”利用激光治疗仪器中使用的穿刺套管针，其改进之处是先后将针灸针和光纤针插入穿刺套管针，插入的针灸针或光纤针设计有针座，由开有卡槽的圆台与相应的卡销固定。但是使用穿刺导管针，均没有解决光纤的插入和固定的问题。这种针灸针到现在还未能推广，有以下几点原因：In order to allow light energy to enter the body through the optical fiber, the utility model patent CN00205098.6 "A Laser Acupuncture Needle" uses the puncture trocar used in the laser treatment instrument, and its improvement is to insert the acupuncture needle and the optical fiber needle into the puncture cannula The needle, the inserted acupuncture needle or fiber optic needle is designed with a needle seat, which is fixed by a round table with a card slot and a corresponding bayonet pin. However, the use of puncture catheter needles does not solve the problems of insertion and fixation of optical fibers. This kind of acupuncture needle has not been popularized until now, for the following reasons:

1、这种激光针灸针在操作时先用含有针灸针的导管针感受到穴位以后，再拔除针灸针，插入光纤针，操作起来是繁琐的。而且，如果针灸针与穿刺导管之间为紧配合，在拔除时必然抽出体液；即使不是紧配合，也可能抽出体液。因为在针尖处有一个不小于100微米的小孔。在下一步插入光纤时，不论是否重新推入抽出的体液，都可能出现事故。2、光纤加套是常规技术，已经是专业工作者的常识。对于特殊应用，通常加多层套。因此，对于医用光针的加套，也应该有特殊的要求，例如管径和刚度的要求，松套和紧套的要求。该专利对套管没有提到应该考虑到的特殊要求。3、这种激光针灸针尖为圆锥，而光纤针端面，从图上看是平顶。即使用标准石英光纤，直径最小也有110微米。刺入人体的疼痛感会比较大。而如果光纤是裸纤，有折断的危险，也很难确认是否到位。如果光纤带包层，会增加光针的总直径，从而增加病人的疼痛感觉。光纤如果能随意插进拔出，要求导管针内表面抛光，而且肯定会保留一定的间隙，这导致较多不确定因素存在。尽管申明为一次性使用，为保持使用方便和清洁卫生的要求，成本会有大幅度增加。4、带卡槽的圆盘，新设计和加工会比较贵，因为光纤技术属精密技术。5、该实用新型专利是针对针灸，工作范围小而难于得到使用。1. When operating this kind of laser acupuncture needle, use the catheter needle containing the acupuncture needle to feel the acupuncture point first, then pull out the acupuncture needle and insert the fiber optic needle, which is cumbersome to operate. Moreover, if there is a tight fit between the acupuncture needle and the puncture catheter, body fluid must be drawn out when it is pulled out; even if it is not a tight fit, body fluid may be drawn out. Because there is a small hole not less than 100 microns at the tip of the needle. Accidents can occur whether or not the aspirated fluid is re-pushed when the fiber is inserted in the next step. 2. Optical fiber jacketing is a conventional technology, which is common knowledge of professional workers. For special applications, multi-layer sleeves are usually added. Therefore, there should also be special requirements for the sheathing of medical light needles, such as the requirements for tube diameter and rigidity, and the requirements for loose and tight sheaths. The patent is silent on the specific requirements that should be taken into account for the bushing. 3. The tip of this laser acupuncture needle is conical, while the end face of the fiber optic needle is flat top from the picture. Even with standard silica fibers, the minimum diameter is 110 microns. The pain of piercing the human body will be greater. And if the optical fiber is a bare fiber, there is a danger of breaking, and it is difficult to confirm whether it is in place. If the optical fiber is clad, it will increase the overall diameter of the light needle, thereby increasing the pain sensation of the patient. If the optical fiber can be inserted and pulled out at will, the inner surface of the catheter needle is required to be polished, and a certain gap must be reserved, which leads to many uncertain factors. Although it is stated as a one-time use, in order to maintain the requirements of convenience and cleanliness, the cost will increase significantly. 4. For discs with card slots, the new design and processing will be more expensive, because optical fiber technology is a precision technology. 5. This utility model patent is aimed at acupuncture and has a small scope of work and is difficult to use.

另一方面，从波导技术的发展来看，以前追求的目标是能够弯曲和灵活性，使得光能经弯曲的路径到达需要的地方，同时确保光纤不会折断和漏光。光纤的外导管为塑料或尼龙最适合这种要求。即使对于海底光缆用不锈钢增强，也是由钢丝编织的导管，使得能够弯曲。目前，所有光纤都是卷成筒型运输，就是利用了光纤可弯曲的性质。但是当障碍物不能绕过，只能靠穿透、透射、散射或衍射传输时，如何控制和使用光便成了一个亟待解决的技术问题，例如，当人体需要注射光以达到治疗目的时，需要一种能够方便施力且以最短距离准确到达病变部位的器械。本发明中的钢套管光纤采用了退火以增加其韧性，淬火增加其钢度，套管和光纤之间为紧配合，或以粘结剂固化形成实心复合结构光纤。由这种钢套管光纤制造的光针可以以最短的直线距离准确到达病变部位。On the other hand, from the perspective of the development of waveguide technology, the previously pursued goal is to be able to bend and be flexible, so that light can reach the required place through a curved path, while ensuring that the optical fiber will not break and leak light. Plastic or nylon outer conduits for optical fibers are most suitable for this requirement. Even for submarine cables reinforced with stainless steel, it is a conduit braided by steel wires that enables bending. At present, all optical fibers are transported in rolls, which takes advantage of the bendable nature of optical fibers. However, when obstacles cannot be circumvented and can only be transmitted by penetration, transmission, scattering or diffraction, how to control and use light has become an urgent technical problem to be solved. For example, when the human body needs to inject light for therapeutic purposes, There is a need for an instrument that can apply force conveniently and accurately reach the lesion with the shortest distance. The steel sleeve optical fiber in the present invention adopts annealing to increase its toughness, and quenching to increase its rigidity, and the sleeve and optical fiber are tightly fitted, or are solidified with a binder to form a solid composite structure optical fiber. The optical needle made of this steel sleeve fiber can accurately reach the lesion with the shortest straight-line distance.

发明内容Contents of the invention

本发明的目的在于克服现有技术的缺点，提供一种实现体内光能量治疗，用便捷的办法，使激光通过光纤传输直接进入体内进行治疗，突破生物机体和组织对光不透明的限制，减少光能量损耗。同时，利用光学极高灵敏度的特点，用光探测体内的生理过程。The purpose of the present invention is to overcome the shortcomings of the prior art, provide a light energy therapy in the body, and use a convenient method to make the laser light directly enter the body for treatment through optical fiber transmission, break through the limitations of biological organisms and tissues on light opacity, and reduce the amount of light. energy loss. At the same time, using the characteristics of extremely high optical sensitivity, the physiological process in the body is detected with light.

本发明的目的通过以下技术方案来实现：The purpose of the present invention is achieved through the following technical solutions:

一种即插即用的医用光针包括光纤(3)和不锈钢套管(1)，不锈钢套管(1)位于外层，内层是光纤(3)，在光纤和不锈钢管之间填充粘结剂(2)固化形成实心复合结构；医用光针的针尖端为一次性注射针针尖形状，医用光针的另一端制成可插入光纤耦合器的光针接插头。A plug-and-play medical optical needle includes an optical fiber (3) and a stainless steel sleeve (1), the stainless steel sleeve (1) is located on the outer layer, the inner layer is an optical fiber (3), and glue is filled between the optical fiber and the stainless steel tube. The binder (2) solidifies to form a solid composite structure; the needle tip of the medical optical needle is in the shape of a disposable injection needle, and the other end of the medical optical needle is made into an optical needle connector plug that can be inserted into the optical fiber coupler.

所述的针尖端的光纤有三种端面：与不锈钢套管表面平齐的光滑平面、有聚光作用的光滑球面和表面不光滑的粗糙表面。The optical fiber at the tip of the needle has three types of end faces: a smooth plane flush with the surface of the stainless steel sleeve, a smooth spherical surface with a light-gathering effect, and a rough surface with an unsmooth surface.

所述光针接插头，精密设计为可插入光纤耦合器紧配合结构，经光纤适配器连接，成为光纤耦合器的组成部分。The optical needle connector is precisely designed to be inserted into the tight fit structure of the optical fiber coupler, connected through the optical fiber adapter, and becomes a component of the optical fiber coupler.

所述光针接插头具有与连接光纤相同的外径，与耦合器的一种耦合方式是将接插头在V型槽(5)和定位销(4)准确引导下插入光纤耦合器，实现高效耦合，是一种即插即用的器件。The optical needle connector has the same outer diameter as the connecting optical fiber, and one coupling method with the coupler is to insert the connector into the fiber optic coupler under the accurate guidance of the V-shaped groove (5) and the positioning pin (4), so as to realize high-efficiency Coupling is a plug-and-play device.

本发明的一种即插即用的医用光针在针头部位的外部形状和尺寸与一次性注射用针针头相同，一种方案是采用已经有的外径0.7毫米和0.45毫米两种医用注射针，针尖角度12度。也可以设计制造直径小于0.5毫米的各种直径和各种长度的光针，这种针是实心的，只能通光。A plug-and-play medical optical needle of the present invention has the same external shape and size as the disposable injection needle. One solution is to use two existing medical injection needles with outer diameters of 0.7 mm and 0.45 mm. , the tip angle is 12 degrees. It is also possible to design and manufacture optical needles of various diameters and lengths with a diameter less than 0.5 mm. This needle is solid and can only pass through light.

针尖端的光纤的端面根据需要制成平面和球面的形式，满足不同的照明区域需要和有利于诊断信息的采集。球形端面，起微透镜作用。微透镜的作用是使出射光在前方会聚。这种端面由激光端面融化冷却自然成型。针尖的光纤端面还可以有其他形式。根据临床需要，例如需要更柔和以及更宽范围的照明，端面可以制成表面不光滑的粗糙表面。The end face of the optical fiber at the tip of the needle is made into a plane or a spherical form as required, which meets the needs of different illumination areas and facilitates the collection of diagnostic information. The spherical end face acts as a microlens. The function of the microlens is to converge the outgoing light in front. This end face is formed naturally by melting and cooling of the laser end face. The fiber end face of the needle point can also have other forms. Depending on clinical needs, such as softer and wider range illumination, the end faces can be made with a matte rough surface.

采用注射针的形式，设计外形如注射针，内部结构为光波导，并具体化为光纤，光针直接插入体内直到病变部位。光针的另一端通过耦合器从包括半导体激光器在内的各种可调谐光源或宽带光源获取光能量，实现光能量注入。增加分束耦合器可将治疗和诊断信息传送到相关探测器用于分析。In the form of an injection needle, the shape is designed like an injection needle, and the internal structure is an optical waveguide, which is embodied as an optical fiber. The optical needle is directly inserted into the body until the lesion is reached. The other end of the optical needle obtains optical energy from various tunable light sources or broadband light sources including semiconductor lasers through a coupler to realize optical energy injection. The addition of a beam-splitting coupler can route therapeutic and diagnostic information to associated detectors for analysis.

实施例2Example 2

本发明可以制作成一种便携式医用光针，用发光二极管和纽扣电池做光源，利用用红光，可用作针灸或者对准血栓，化解血栓。输出光的光谱波段和功率由发光二极管本身控制，照射剂量由工作时间和电池的寿命控制。如图5所示的一种结构，用普通红色高亮度发光二极管。小型的发光二极管与纽扣电池直接装入不锈钢套管1内。市售的小型发光二极管直径是3毫米。但是芯片尺度仅0.24毫米。直接采用芯片将引线导出，套筒底部装反射镜。套筒上紧时二极管亮，同时聚焦耦合进入光纤再耦合进入医用光针，从底部透明窗口可见到散射光。这种耦合对准的夹紧对准方法如图6所示。由图7看到同一尺度的钢套光纤制成二极管的输出耦合器的输出端面为球面，该输出耦合器平放在精密陶瓷制成的V型槽5上，由定位销4夹紧。使用时，平顶抛光的医用光针7直接插入，直到与二极管的输出耦合器8顶端球面接触，上紧套筒直到二极管点亮，医用光针就可以工作了。输出耦合器的球形端面，可用专门的模具，模压成型，直接成为发光二极管的外形封装，使器件的结构更为紧凑。具有方便携带，操作简单的优点。The invention can be made into a portable medical light needle, which uses a light-emitting diode and a button battery as a light source, and uses red light, which can be used for acupuncture or aiming at thrombus to dissolve thrombus. The spectral band and power of the output light are controlled by the light-emitting diode itself, and the irradiation dose is controlled by the working time and the life of the battery. A structure as shown in Figure 5 uses ordinary red high-brightness light-emitting diodes. Small light-emitting diodes and button batteries are directly packed into thestainless steel casing 1 . Commercially available small LEDs are 3 mm in diameter. But the chip size is only 0.24 mm. Directly use the chip to lead out the lead wire, and install the reflector at the bottom of the sleeve. When the sleeve is tightened, the diode is on, and at the same time, the focus is coupled into the optical fiber and then coupled into the medical light needle, and the scattered light can be seen from the transparent window at the bottom. The clamping alignment method of this coupling alignment is shown in FIG. 6 . It can be seen from Fig. 7 that the output end face of the output coupler made of the steel-sheathed optical fiber of the same scale is spherical, and the output coupler is placed flat on the V-groove 5 made of precision ceramics and clamped by thepositioning pin 4 . When in use, the flat-top polished medicallight needle 7 is directly inserted until it contacts with the spherical surface of the top of the output coupler 8 of the diode, and the sleeve is tightened until the diode lights up, and the medical light needle can work. The spherical end face of the output coupler can be molded with a special mould, and directly becomes the shape package of the light-emitting diode, which makes the structure of the device more compact. The utility model has the advantages of being convenient to carry and easy to operate.

实施例3Example 3

本发明还可以达到精密控制能量和监控治疗效果，工作原理如下：医用光针的光针接插头接入光纤跳线，跳线另一端接一分二耦合器6，如图8：一分二耦合器6，有三个端口。端口一15连接到激光器，是光的输入口。端口二16是输出口，直接与光针耦合，然后从针尖输出光能量。在针尖处的反射光和激发的光荧光会被收集原路返回，按方向耦合原理从端口三17出，端口三17连接到探测器，变成电信号进行分析处理。输入光为光波长可调谐的半导体激光器，因此可以在一定范围调节入射光波长，或者方便地更换不同波长的激光器。照射计量也在光源处控制。激光器工作于连续和脉冲两种模式。在连续工作模式，照射剂量直接由输出功率和照射时间控制。由于半导体激光器为注入受激辐射，照射剂量控制可直接由电子学方法完成。在脉冲工作模式，可以由脉冲数和每脉冲功率的乘积决定，所以注入能量能更精密地控制。The present invention can also achieve precision control of energy and monitoring of treatment effects. The working principle is as follows: the optical needle connector of the medical optical needle is connected to the optical fiber jumper, and the other end of the jumper is connected to the one-to-twocoupler 6, as shown in Figure 8: one-to-twoCoupler 6, has three ports. Port one 15 is connected to the laser and is the light input port.Port 2 16 is an output port, which is directly coupled with the light needle, and then outputs light energy from the needle tip. The reflected light at the needle tip and the excited light and fluorescence will be collected and returned to the original path, and output from the port three 17 according to the principle of directional coupling, and the port three 17 is connected to the detector, and becomes an electrical signal for analysis and processing. The input light is a semiconductor laser with tunable optical wavelength, so the wavelength of the incident light can be adjusted within a certain range, or lasers with different wavelengths can be easily replaced. Exposure metering is also controlled at the light source. Lasers work in both continuous and pulsed modes. In continuous working mode, the irradiation dose is directly controlled by the output power and irradiation time. Since the semiconductor laser is injected with stimulated radiation, the irradiation dose control can be done directly by electronic methods. In the pulse mode, it can be determined by the product of the number of pulses and the power per pulse, so the injected energy can be more precisely controlled.
