Translated fromChinese技术领域technical field
本发明涉及医疗器械领域，特别是涉及一种导丝消融电极、第一消融装置、第二消融装置及消融方法。The present invention relates to the field of medical devices, in particular to a guide wire ablation electrode, a first ablation device, a second ablation device and an ablation method.
背景技术Background technique
消融是一种微创手术，可分为化学消融和物理消融；临床常用物理消融，物理消融包括射频消融、微波消融、冷冻消融、超声消融、激光消融等等；射频消融是较为成熟且常用的消融方式，射频消融主要用于人体组织器官结节、阻塞、肿瘤等疾病的治疗；射频消融治疗是将消融电极穿刺到病灶部位，通过射频输出功率，使病灶部位细胞温度升高，发生变性，最终使病变部位组织坏死，通过人体正常代谢吸收清除，达到消除结节、疏通阻塞、消除肿瘤的目的。Ablation is a minimally invasive surgery, which can be divided into chemical ablation and physical ablation; physical ablation is commonly used in clinical practice, and physical ablation includes radiofrequency ablation, microwave ablation, cryoablation, ultrasound ablation, laser ablation, etc.; radiofrequency ablation is more mature and commonly used. Ablation method, radiofrequency ablation is mainly used for the treatment of human tissue and organ nodules, obstructions, tumors and other diseases; radiofrequency ablation is to puncture the ablation electrode into the lesion site, and through the radio frequency output power, the temperature of the cells in the lesion site is increased, resulting in degeneration, Eventually, the tissue at the lesion site is necrotic, and is absorbed and eliminated through the normal metabolism of the human body to achieve the purpose of eliminating nodules, clearing blockages, and eliminating tumors.
射频消融治疗需要配套射频消融系统，包含射频消融仪和射频消融电极，射频消融电极能够作用于人体管道中的梗阻部位，对其进行消融。治疗器官或部位不同，病灶大小不同、病灶性质不同，所使用的射频消融电极不同，如治疗恶性胆管梗阻使用胆道射频消融电极。Radiofrequency ablation treatment requires a supporting radiofrequency ablation system, including a radiofrequency ablation instrument and a radiofrequency ablation electrode. The radiofrequency ablation electrode can act on the obstructed part of the human pipeline to ablate it. Different organs or parts to be treated, different size of lesions, different nature of lesions, and different radiofrequency ablation electrodes are used. For example, biliary radiofrequency ablation electrodes are used in the treatment of malignant bile duct obstruction.
人的胆管正常直径为6-8毫米，总长度为4-8厘米，胆道梗阻可能存在小范围一点，可能存在大范围一段，可能部分阻塞，胆道内仅有狭小的通路，可能完全阻塞，看不到胆道通路。现有的消融方式存在以下缺点：1.常规胆道射频消融电极仅有消融功能，这种电极往往直径较大，直径较大的原因是中间有引导丝孔，要通过引导丝引导才能到达胆管梗阻部位，但是不能直接通过胆管阻塞严重的部位；2.由于常规引导丝前端为比较柔软的塑料头，无消融功能，而且很柔软，无法穿过梗阻比较严重的地方；3.常规引导丝无法穿过梗阻严重部位，所以更无法通过常规引导丝将常规胆道射频消融电极的工作头端引导到梗阻严重部位的中心位置，导致常规胆道射频消融电极的工作头端无法到达病灶中心，进行完全消融，失去治疗机会。The normal diameter of the human bile duct is 6-8 mm, and the total length is 4-8 cm. There may be a small area of biliary obstruction, there may be a large area, and it may be partially blocked. There is only a narrow passage in the bile duct, which may be completely blocked. See Biliary access is not available. The existing ablation methods have the following shortcomings: 1. Conventional biliary radiofrequency ablation electrodes only have ablation function, and these electrodes are often larger in diameter. The reason for the larger diameter is that there is a guide wire hole in the middle, and bile duct obstruction can only be reached through the guide wire. 2. Because the front end of the conventional guide wire is a relatively soft plastic tip, it has no ablation function, and it is very soft, so it cannot pass through the severely obstructed part; 3. The conventional guide wire cannot be pierced through The working head of the conventional biliary radiofrequency ablation electrode cannot be guided to the center of the severely obstructed part through the conventional guide wire, so that the working head of the conventional biliary radiofrequency ablation electrode cannot reach the center of the lesion for complete ablation. Lost opportunity for treatment.

本实施例还提供一种第二消融装置，包括导丝消融电极100、第二内窥镜和射频消融仪，连接器103用于与射频消融仪连接，第二内窥镜用于将导丝消融电极100引导至梗阻部位，且第二内窥镜能够进入具有梗阻部位300的人体管道中并伸至梗阻部位300，即可以通过第二内窥镜对梗阻部位300的消融工作进行观察。具体地，第二内窥镜的外径小于具有梗阻部位的人体管道，使得第二内窥镜能够进入具有梗阻部位的人体管道。This embodiment also provides a second ablation device, including a guide
本实施例还提供一种基于第二消融装置的消融方法，包括以下步骤：通过第二内窥镜上的导丝孔将导丝消融电极100的工作端102引导至梗阻部位300，第二内窥镜的头端能够进入具有梗阻部位300的人体管道中并伸至梗阻部位300，开启射频消融仪，射频消融仪通过连接器103将射频能量传递到导丝内芯101，射频能量再通过导丝内芯101传递到工作端102，工作端102在第二内窥镜的观察下对梗阻部位300进行消融，即能够在目视下对梗阻部位300进行精准多点重复消融。具体地，通过在X光机的观察下进行消融的方式是间接观察的，且是在消融前、消融中和消融后选取多个时间节点进行观察，即采用间断性观察，通过第二内窥镜的头端在目视下进行消融的方式是直接目视观察的，观察视野更加清晰，同时，可在消融过程中对消融效果进行持续性观察，能够更加准确地多次移动工作端102进行精准多点重复消融。通过精准多点重复消融能够对梗阻部位300进行有效疏通，进而能够精准地对梗阻严重的患者进行治疗，同时具有对非治疗部位损伤小，安全性高的特点。This embodiment also provides an ablation method based on the second ablation device, including the following steps: guiding the working
具体地，第二内窥镜的直径为2.4～3.8mm，导丝孔的孔径为1.2mm。本实施例中的第二内窥镜为新型胆道内窥镜。Specifically, the diameter of the second endoscope is 2.4-3.8 mm, and the diameter of the guide wire hole is 1.2 mm. The second endoscope in this embodiment is a novel biliary endoscope.
可见，本实施例中的第一消融装置克服了常规引导丝前端是软头且无消融功能、不能对阻塞严重部位进行通道建设并引导消融电极200至阻塞严重部位中心的缺陷，实现了对梗阻严重的患者的治疗，增加了梗阻严重的患者的治疗机会。本实施例中的第二消融装置通过将导丝消融电极100的工作端102引导至梗阻部位300，然后在目视下对梗阻部位300进行精准多点重复消融，进而能够精准地对梗阻严重的患者进行治疗，还具有对非治疗部位损伤小，安全性高的特点。同时，导丝消融电极100一方面能够引导自身在具有多个弯曲处的人体管道中穿行，另一方面能够用作引导丝对消融电极200进行引导，可见，本实施例中的导丝消融电极100具有引导、显影和消融功能。It can be seen that the first ablation device in this embodiment overcomes the defects that the front end of the conventional guide wire is a soft tip and has no ablation function, and it cannot build a channel for the severely blocked part and guide the
