背景技术Background technique
脊髓损伤(Spinal cord injury，SCI)是世界性难题，其病理过程分为原发性损伤和继发损伤两个阶段，继发免疫炎症反应是影响SCI预后的关键环节。SCI尚无有效的治疗方法，临床上以手术减压、神经营养为主，但对于严重损伤的治疗效果不佳；新兴的治疗方法如免疫抑制药物、细胞移植、生物材料等均存在着伦理问题、化学毒副作用等不足，无法在临床推广应用。Spinal cord injury (SCI) is a global problem. Its pathological process is divided into two stages: primary injury and secondary injury. Secondary immune inflammatory response is the key link affecting the prognosis of SCI. There is no effective treatment for SCI. Surgical decompression and neurotrophy are the main treatments in clinical practice, but the treatment effect is poor for severe injuries. Emerging treatments such as immunosuppressive drugs, cell transplantation, and biomaterials have ethical issues, chemical toxicity and side effects, and cannot be promoted and applied in clinical practice.
光生物调节治疗(Photobiomodulation，PBM)因其抑炎效果明确、操作简便、无创，已被广泛应用于多种疾病的临床治疗，在神经损伤修复中PBM也具有明确的效果。前期研究发现，PBM可以抑制炎性反应、减少胶质瘢痕形成、保护神经元活性、促进神经再生，有效促进SCI动物的运动功能恢复，具有良好的应用前景。Photobiomodulation (PBM) has been widely used in the clinical treatment of various diseases due to its clear anti-inflammatory effect, simple operation and non-invasiveness. PBM also has a clear effect in nerve injury repair. Previous studies have found that PBM can inhibit inflammatory response, reduce glial scar formation, protect neuronal activity, promote nerve regeneration, and effectively promote the recovery of motor function in SCI animals, which has good application prospects.
目前，针对SCI的PBM治疗主要采用经皮照射或血管内照射。由于脊髓组织所处的位置较深，骨质结构对激光有遮挡作用、皮肤肌肉组织对光能有严重散射和吸收，使得有效治疗剂量的光能无法完全到达脊髓表面，导致疗效不确切，严重限制PBM在SCI治疗中的应用。针对上述问题，在《光生物调节治疗在急性脊髓损伤临床应用中的可行性研究》中创新研制出一种可嵌入体内、对脊髓损伤部位进行直接照射的360°发光光纤，动物实验验证了该方法的有效性和安全性，并率先在国际上开展了360°光纤介导的PBM治疗SCI的临床可行性研究，取得良好的预期结果。At present, PBM treatment for SCI mainly adopts percutaneous irradiation or intravascular irradiation. Due to the deep location of spinal cord tissue, the bone structure blocks the laser, and the skin and muscle tissue seriously scatter and absorb the light energy, so that the effective therapeutic dose of light energy cannot completely reach the surface of the spinal cord, resulting in uncertain efficacy, which seriously limits the application of PBM in SCI treatment. In response to the above problems, in the "Feasibility Study of Photobiomodulation Therapy in the Clinical Application of Acute Spinal Cord Injury", a 360° luminous optical fiber that can be embedded in the body and directly irradiate the spinal cord injury site was innovatively developed. Animal experiments verified the effectiveness and safety of this method, and took the lead in the international clinical feasibility study of 360° fiber-mediated PBM treatment of SCI, and achieved good expected results.
但是，光纤发光端在体内椎板上方直接照射脊髓损伤时，面临光纤左右摆动、偏离照射目标区域的不足之处，目前主要依靠可吸收线对光纤发光端进行适当固定，防止光纤脱离照射区域。然而，使用可吸收线固定光纤照射端，无法有效掌控松紧程度，固定过于松弛，光纤可能脱离照射区域，无法达到治疗效果；固定过紧，面临光纤无法拔出体外的临床问题，需要二次手术取出，造成不必要的二次手术创伤。However, when the optical fiber light-emitting end is directly irradiating the spinal cord injury above the vertebral plate in the body, there is the disadvantage that the optical fiber swings left and right and deviates from the target irradiation area. Currently, it mainly relies on absorbable sutures to properly fix the optical fiber light-emitting end to prevent the optical fiber from leaving the irradiation area. However, when using absorbable sutures to fix the optical fiber irradiation end, it is impossible to effectively control the tightness. If the fixation is too loose, the optical fiber may leave the irradiation area and fail to achieve the treatment effect; if the fixation is too tight, there is a clinical problem that the optical fiber cannot be pulled out of the body, and a second surgery is required to remove it, causing unnecessary secondary surgical trauma.

本发明的目的是提供一种可吸收光纤卡持器，以解决现有技术存在的问题，能够稳定地对嵌入体内的光纤进行夹持固定，防止光纤摆动，保证治疗效果，并且光纤取出方便，不会造成二次手术创伤。The purpose of the present invention is to provide an absorbable optical fiber holder to solve the problems existing in the prior art. It can stably clamp and fix the optical fiber embedded in the body to prevent the optical fiber from swinging, ensure the treatment effect, and make it easy to remove the optical fiber without causing secondary surgical trauma.
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
如图1～3所示，本实施例提供一种可吸收光纤卡持器，包括卡持器本体1，卡持器本体1上设有棘突卡槽2和光纤卡槽3，棘突卡槽2用于卡接固定于脊柱棘突4上，光纤卡槽3用于卡持固定光纤发光端5，棘突卡槽2卡接固定于脊柱棘突4上时，光纤卡槽3卡持固定光纤发光端5并能够使光纤发光端5位于椎板8外侧以对脊髓损伤处照射治疗，卡持器本体1为人体可吸收材料制成。As shown in Figures 1 to 3, this embodiment provides an absorbable optical fiber holder, including a holder body 1, on which a spinous process slot 2 and an optical fiber slot 3 are provided. The spinous process slot 2 is used to be clamped and fixed on the spinous process 4 of the spine, and the optical fiber slot 3 is used to clamp and fix the optical fiber light-emitting end 5. When the spinous process slot 2 is clamped and fixed on the spinous process 4 of the spine, the optical fiber slot 3 clamps and fixes the optical fiber light-emitting end 5 and enables the optical fiber light-emitting end 5 to be located outside the vertebral plate 8 for irradiation treatment of the spinal cord injury. The holder body 1 is made of human absorbable material.
在将光纤发光端5通过皮肤9嵌入体内对脊髓损伤部位进行照射治疗时，通过棘突卡槽2将卡持器本体1卡接固定于脊柱棘突4上，并通过光纤卡槽3将光纤发光端5卡持固定，使光纤发光端5位于椎板8外侧，以对脊髓损伤处进行光生物调节治疗，采用可吸收光纤卡持器对光纤发光端5进行卡持固定，可根据光纤的直径制作相应的光纤卡槽3，使光纤发光端5能够松紧适中的卡接在光纤卡槽3中，防止光纤发光端5摆动，保证治疗效果，拔出光纤时，光纤顺着光纤卡槽3退出，不影响光纤的拔出，同时，卡持器本体1为人体可吸收材料制成，可采用生物降解材料制作，体内自然降解，无需取出，避免了采用可吸收线固定光纤发光端无法掌控松紧程度，固定过于松弛而使光纤摆动脱离照射目标区域无法达到治疗效果，固定过紧又难以拔出光纤，需二次手术取出光纤的弊端，采用可吸收光纤卡持器，光纤能够顺利取出，不需二次手术，不会造成二次手术创伤。When the optical fiber light-emitting end 5 is embedded in the body through the skin 9 to perform irradiation treatment on the spinal cord injury site, the holder body 1 is clamped and fixed on the spinous process 4 of the spine through the spinous process clamping groove 2, and the optical fiber light-emitting end 5 is clamped and fixed through the optical fiber clamping groove 3, so that the optical fiber light-emitting end 5 is located outside the vertebral plate 8, so as to perform photobiomodulation treatment on the spinal cord injury site. The optical fiber light-emitting end 5 is clamped and fixed by an absorbable optical fiber holder, and the corresponding optical fiber clamping groove 3 can be made according to the diameter of the optical fiber, so that the optical fiber light-emitting end 5 can be clamped in the optical fiber clamping groove 3 with appropriate tightness to prevent the optical fiber light-emitting end 5 from swinging, thereby ensuring the treatment. The optical fiber can be pulled out along the optical fiber slot 3 without affecting the pulling out of the optical fiber. At the same time, the holder body 1 is made of human absorbable material and can be made of biodegradable material. It will naturally degrade in the body and does not need to be taken out. This avoids the problem that the absorbable line is used to fix the optical fiber light-emitting end, the tightness cannot be controlled, the fixation is too loose, and the optical fiber swings out of the irradiation target area and cannot achieve the therapeutic effect, and the fixation is too tight and it is difficult to pull out the optical fiber, and a secondary operation is required to remove the optical fiber. By using an absorbable optical fiber holder, the optical fiber can be smoothly removed without a secondary operation and will not cause secondary surgical trauma.
