一种根管锉和根管治疗仪Root canal file and root canal therapy instrument

技术领域technical field

本发明涉及医疗口腔科激光治疗技术领域，特别涉及一种根管锉和根管治疗仪。The invention relates to the technical field of medical stomatology laser treatment, in particular to a root canal file and a root canal treatment instrument.

背景技术Background technique

在牙科根管治疗中，根管系统的细菌感染是导致根尖周和牙髓产生病变的主要原因，因此根管治疗的主要目标是建立一个干净的根管系统。然而由于根管系统复杂，完全清除细菌和碎屑，形成无菌的根管非常困难。In dental root canal treatment, bacterial infection of the root canal system is the main cause of periapical and pulp lesions, so the main goal of root canal treatment is to establish a clean root canal system. However, due to the complexity of the root canal system, it is very difficult to completely remove bacteria and debris to form a sterile root canal.

目前，都是用消毒剂对根管进行消毒，但是消毒剂会被根管深层的污垢层所阻碍。研究表明，激光照射能够消除根管中的碎屑和污垢层，但是激光在根管内受到两个方面限制：1.从光纤尖端发出的激光能量沿根管方向发射，而不是沿根管侧壁方向发射，因此，使用激光几乎不能360°均匀覆盖到根管内壁；2.安全问题，如果激光光纤太靠近根尖孔，激光能量可能会投射过根尖孔。Currently, root canals are sterilized with antiseptics, but the antiseptics are hindered by the deep layer of dirt in the root canal. Studies have shown that laser irradiation can eliminate debris and dirt layers in the root canal, but the laser is limited by two aspects in the root canal: 1. The laser energy emitted from the fiber tip is emitted in the direction of the root canal, not along the side of the root canal Therefore, the use of laser can hardly cover the inner wall of the root canal evenly at 360°; 2. Safety issues, if the laser fiber is too close to the apical foramen, the laser energy may be projected through the apical foramen.

其中，旋转锉4安装于弯手机1，该弯手机1能够带动旋转锉4旋转；如图所示，旋转锉4为锥形；Wherein, therotary file 4 is installed on the contra-angle handpiece 1, and the contra-angle handpiece 1 can drive therotary file 4 to rotate; as shown in the figure, therotary file 4 is tapered;

光纤7安装于旋转锉4，该旋转锉4能够带动光纤7旋转，且光纤7的尾部(图中的右端)与旋转锉4的转轴之间设有夹角；从上述的技术方案可以看出，本发明实施例提供的根管锉，采用激光和旋转锉结合的方式消毒，使激光能够向根管内壁发射，既利用了激光的快速消毒的作用，又能保证根管内部能消毒彻底；本方案利用激光来进行荡洗消毒，消毒效果好，效率高，准确率高，对根管荡洗彻底；结合了牙科弯手机和激光，激光导光装置不插时可以用于根管预备，插上就能用于根管荡洗消毒，方便医生操作，学习成本低。Theoptical fiber 7 is installed in therotary file 4, therotary file 4 can drive theoptical fiber 7 to rotate, and there is an angle between the tail of the optical fiber 7 (the right end in the figure) and the rotating shaft of therotary file 4; it can be seen from the above technical scheme , The root canal file provided by the embodiment of the present invention is sterilized by combining laser and rotary file, so that the laser can be emitted to the inner wall of the root canal, which not only utilizes the effect of rapid disinfection of the laser, but also ensures that the inside of the root canal can be thoroughly sterilized; This solution uses laser for cleaning and disinfection, which has good disinfection effect, high efficiency and high accuracy, and thoroughly cleans the root canal; it combines dental contra-angle handpieces and lasers, and can be used for root canal preparation when the laser light guide device is not inserted.

具体的，导光体的出光端设有弯曲头71，其结构可以参照图3所示；Specifically, the light-emitting end of the light guide is provided with abending head 71, and its structure can be referred to as shown in FIG. 3 ;

旋转锉4的尾端侧壁开设有缺口42，弯曲头71对位安装于缺口42，夹角α为锐角。则随着旋转锉4的运动，光纤7的尾部旋转覆盖四周；即旋转锉4沿根管方向放置时，光纤7的尾部不再沿根管方向发射，而是沿根管侧壁方向发射。Anotch 42 is opened on the side wall of the tail end of therotary file 4, and thebending head 71 is installed in alignment with thenotch 42, and the included angle α is an acute angle. Then along with the movement of therotary file 4, the tail of theoptical fiber 7 rotates to cover the surrounding; that is, when therotary file 4 is placed along the direction of the root canal, the tail of theoptical fiber 7 no longer emits along the direction of the root canal, but emits along the direction of the side wall of the root canal.

The function of themarking block 5 is to allow the doctor to pay attention to the distance between the file and the apical foramen during operation, so as to avoid the laser energy from penetrating the apical foramen.

作为优选，标记块5比控制环6更靠近旋转锉4的头端，其结构可以参照图1和图2所示，以便于医生观察标记块5，则预设提醒距离大于预设安全距离。具体的，控制环6的外径大于标记块5的外径，以便于触碰到牙齿。Preferably, the markingblock 5 is closer to the head end of therotary file 4 than thecontrol ring 6, and its structure can be shown in Figure 1 and Figure 2, so that the doctor can observe themarking block 5, and the preset reminder distance is greater than the preset safety distance.

根管荡洗消毒的工作原理：The working principle of root canal cleaning and disinfection:

激光发射装置发射激光，透过导光光纤21传到聚光透镜24前，聚光透镜24对激光具有聚焦的作用，使激光聚集在光纤7上，最后传到光纤7尾部后作用于根管内壁，进行消毒。与此同时，如图5所示，在消毒的过程中注射针向根管中注入清洗剂让激光对根管内壁的病菌和碎屑进行荡洗。与此同时，弯手机1内机芯旋转带动旋转锉4进行旋转，此时激光就会随着旋转锉4的旋转在根管内部进行360°旋转消毒，同时控制环6下表面有阻尼材料，与牙齿接触后能够停止旋转，控制环6和旋转锉4之间的螺纹能够控制旋转锉4每转一圈的下降距离，保证消毒面积能够覆盖整个根管，标记块5的作用是让医生操作时注意锉离根尖孔的距离，避免激光能量穿透根尖孔。之后随着旋转锉4的深入，根管内径会越来越小，这时候就能发挥旋转锉4的优势，既能保证内消毒到根管内部，又能保证清洗消毒效果。The laser emitting device emits laser light, which passes through the light-guidingoptical fiber 21 to the front of thecondenser lens 24, and thecondenser lens 24 has a focusing effect on the laser light, so that the laser light is concentrated on theoptical fiber 7, and finally transmitted to the tail of theoptical fiber 7 to act on the root canal The inner wall is disinfected. At the same time, as shown in Figure 5, during the disinfection process, the injection needle injects cleaning agent into the root canal to allow the laser to clean the germs and debris on the inner wall of the root canal. At the same time, the rotation of the inner movement of the contra-angle handpiece 1 drives therotary file 4 to rotate. At this time, the laser will perform 360° rotation disinfection inside the root canal with the rotation of therotary file 4. At the same time, the lower surface of thecontrol ring 6 has a damping material. The rotation can be stopped after contact with the tooth, and the thread between thecontrol ring 6 and therotary file 4 can control the descending distance of therotary file 4 per revolution, ensuring that the disinfection area can cover the entire root canal. The function of themarking block 5 is to allow the doctor to operate Pay attention to the distance between the file and the apical foramen to prevent the laser energy from penetrating the apical foramen. Later, as therotary file 4 goes deeper, the inner diameter of the root canal will become smaller and smaller. At this time, the advantages of therotary file 4 can be brought into play, which can not only ensure the internal disinfection to the inside of the root canal, but also ensure the cleaning and disinfection effect.

替代方案：1.可将光纤尾部做成有多个弯曲的光纤，保证转速即使过快也能均匀覆盖根管侧壁；Alternatives: 1. The tail of the optical fiber can be made into an optical fiber with multiple bends to ensure that the side wall of the root canal can be evenly covered even if the rotation speed is too fast;

2.导光手柄和聚光手柄之间、支撑后盖和弯手机之间可通过嵌入等其他方式连接；2. Between the light guide handle and the spotlight handle, between the support back cover and the contra-angle handpiece can be connected by embedding or other methods;
