Description

具有实时测温与消融为一体的高性能水冷微波消融天线 High-performance real-time temperature measurement and the water-cooled microwave ablation antenna integrated extinction

技术领域 FIELD

[0001] 本实用新型涉及一种具有实时测温与消融为一体的高性能水冷微波消融肿瘤之医疗器械,属于医用微波技术应用领域。 High-performance water-cooled microwave [0001] The present invention relates to a real-time integration of the temperature of the tumor destructive ablation medical devices, belonging to the application of microwave field of medical technology.

背景技术 Background technique

[0002] 进入21世纪以来,医用微波技术发展迅速,特别是微波消融肿瘤已迅速发展成为临床肿瘤治疗中的一种主要手段,以其肿瘤升温速度快、瘤内温度高、消融范围大,受碳化和血流影响小等突出优点,在实体肿瘤特别是对较大实体肿瘤的治疗中发挥着越来越重要的作用,临床应用的普及率也越来越高,应用范围已涉及胸部、腹部及盆腔的多种良、恶性肿瘤的临床手术。 [0002] In the 21st century, the rapid development of microwave technology for medical, particularly microwave ablation tumor has rapidly developed into one of the main means of clinical cancer therapy, their tumors heating speed, high intratumoral temperatures, a large extent of the ablation, by carbonation and impact of small blood and other prominent advantages, especially to play in the treatment of solid tumors larger solid tumors in an increasingly important role in the penetration rate of clinical applications have become more sophisticated, the scope of application has been involved in the chest, abdomen and a variety of clinical pelvic surgery benign and malignant tumors.

[0003] 微波消融治疗的特征是,在B超或CT等现代影像的引导下,微波天线(针状手术器具)经皮微创介入到组织内部,通过微波热效应致使癌细胞急速升温等物理过程,来实施肿瘤的原位灭活。 [0003] Microwave ablation characterized in that, in modern guidance image or the like B-CT, the microwave antenna (needle-like surgical instrument) into the interior of percutaneous minimally invasive tissue by microwave thermal effect rapid heating causes cancer and other physical processes , inactivation of a tumor in situ to implement. 因此,为达到提闻疗效,提闻肿瘤治愈率和提闻术后康复水平等最基本的肿瘤治疗的目的,仅凭医护人员的高尚医德和精湛医术还不行,还必须配套质量稳定和性能上乘的治疗器械与设备,为微波消融手术作可靠的保障。 Therefore, the aim is to achieve the effect of lifting the smell, the smell mention cancer cure rates and raise the level of smell rehabilitation after other basic cancer treatment, medical staff alone noble medical ethics and superb medical skills is not enough, you must also complete stable quality and superior performance treatment equipment and equipment for microwave ablation procedures for reliable protection.

[0004] 然而,现有的微创介入式分支领域里,在肿瘤微波消融过程中,肿瘤的温度与测量——这一至关重要的临床参数与关键技术,迄今为止没有得到实质性的解决。 [0004] However, the existing field of minimally invasive branches in the microwave tumor ablation process, the temperature and the measured tumor - this vital clinical parameters and key technologies, so far not been substantially resolved.

[0005] 众所周知,细胞的存活、病灶的治愈、肿瘤细胞的凝固坏死等细胞和组织的病理变化,归根结底取决于其细胞和组织的温度变化,而现有临床中,肿瘤微波消融的结果往往是由经验丰富的医生凭借B超或CT等影像来判断,再辅以从布设在肿瘤周围的测温针获取温度信息,来得出癌细胞凝固坏死的结论。 [0005] It is well known pathological changes of cells and tissues cell survival, heal lesions, coagulation necrosis of tumor cells, which ultimately depends on the temperature change of cells and tissues, whereas the conventional clinical, tumor microwave ablation often results with other B or CT images judged by experienced physicians, supplemented acquires the temperature information from the temperature surrounding the tumor laid needle to draw conclusions coagulation necrosis of cancer cells. 临床上,为避免癌细胞的接种或转移,布设的测温针是绝对不能碰到癌细胞组织的。 Clinically, in order to avoid vaccination or metastasis of cancer cells, laid the temperature needle is absolutely not touch the cancer tissue. 此外,也有学者试图用其他间接方式进行测温,但均无果O In addition, some scholars tried to measure the temperature in other indirect ways, but no fruit O

[0006] 因此,目前临床上肿瘤微波消融的传统策略是,采用微波消融的热场范围足够大,足以覆盖肿瘤组织体量的办法,旨在着力于“杀死”肿瘤细胞,暂且回避肿瘤的测温问题,回避肿瘤微波消融器械与设备的不足,回避与肿瘤微波消融有关的临床方面的深入研究。 [0006] Therefore, the current policy on traditional clinical oncology microwave ablation is the use of microwave thermal ablation field range large enough to cover the amount of tumor tissue body approach, designed to focus on the "kill" cancer cells, for the time being to avoid cancer temperature measurement problems, avoid shortage microwave tumor ablation devices and equipment, avoiding in-depth study of clinical aspects related to the microwave tumor ablation.

[0021] 本实用新型具有实时测温与消融为一体的高性能水冷微波消融天线的突出特征之处: [0021] The present invention is a water-cooled microwave ablation antenna having high performance real-time temperature measurement of the integrated extinction place prominent features:

[0022] 第一,通过所述金属外导套与半刚同轴电缆的外导体的欧姆连接,使本线天线的开放型部位形成为稳定的统一的精确结构,为本消融天线提供了确定的边界条件,从而使天线上场源在其周围空间所产生的电磁场分布以及天线辐射场具有较强的规律性和一致性,使本消融天线具备了高性能条件及状态。 [0022] First, through the ohmic metal sleeve connected to the outer conductor of a semi-rigid outer conductor coaxial cable, so that an open portion is formed to present a stable line antenna unified precise structure, the present provides methods for determining an ablation antenna boundary conditions, so that the electromagnetic field distribution in the antenna play source space around the generated radiation field and an antenna with a strong consistency and regularity, so that the antenna includes an ablation conditions and high performance state. 由此可将微波消融热场范围抽象地描述为沿天线轴向截面的椭圆图形,如图1所示。 Whereby the microwave thermal ablation field range described abstractly elliptical axial cross section along the antenna pattern, as shown in FIG. 实验证明,微波热场范围的长、短轴尺寸的变化值是与其馈电能量成按一定规律性变化的正比例的函数关系,且具有很好的稳定性、可靠性和高效性。 Experiments show that long-range microwave field, the minor axis size variation value is fed thereto as a function of energy proportional changes by a certain regularity, and has good stability, reliability and efficiency.

[0023] 第二,在肿瘤微波消融的临床应用中,馈电能量是主机输出的微波功率与工作时间的乘积。 [0023] Second, in the clinical application of microwave ablation of the tumor, the feed is the product of energy and operating time of the microwave power output from the host. 微波消融肿瘤凝固坏死的温度是确定值,譬如说是62°C。 Microwave ablation of tumor necrosis coagulation temperature determination value, say a 62 ° C. 在临床上,微波消融天线介入肿瘤组织时,所述匹配杆尾端的温度测量端的位置可恰好处于肿瘤的边缘位置,当温度测量端的肿瘤温度达到62°C时,主机接收此信息,可立即发出指令:中断输出微波功率,也可进行延时控制,此时即可得到原位灭活肿瘤的相应的体量。 Clinically, microwave ablation when the antenna is involved in tumor tissue, the matching position of the temperature measurement end bar trailing end may be just in the edge position of the tumor, when the tumor temperature measurement end reaches 62 ° C, the host receives this information can be sent immediately instruction: interrupt microwave power output, the delay control may be performed, this time to obtain the corresponding body mass in situ inactivation of the tumor. 在肿瘤特质相同的条件下,设置相同的输出微波功率和相同的工作时间参数,从而获得肿瘤微波消融灶的体量将趋于一致。 Tumor characteristics at the same conditions, provided the same output microwave power and the time parameter of the same, so as to obtain an amount of microwave Tumor lesions will converge.

[0025] 第四,根据肿瘤体量大小,选择相应规格的消融天线,可恰如其分的达到肿瘤治疗目的,既取得肿瘤治疗的最佳效果,又能防止因主机馈电能量过大,损伤正常组织和出现心部组织的严重炭化或焦化的现象,造成患者不必要的疼痛,且影响术后的康复。 [0025] Fourth, the amount of tumor size, based on volume, select the appropriate size antenna ablation, cancer treatment can be achieved appropriately purposes, both for best results in the treatment of cancer, but also prevent host feeding power is too large, damage of normal tissue and the phenomenon of serious heart tissue charring or coking, resulting in unnecessary patient pain, and the impact of rehabilitation after surgery.

[0026] 第五、以匹配杆和特制衬管等同样结构,可在消融天线体上布设多点测温,有助于深入研究肿瘤微波消融的有关问题,如图7所示。 [0026] Fifth, the rod structure to match the same special liners and the like, can be laid on the multi-point temperature at the ablation antenna body, help-depth study on problems such as tumors microwave ablation, as shown in FIG.

[0027] 第六、规避了因临床布设旁路测温针可能带来的癌细胞接种或转移的风险。 [0027] Sixth, to avoid the risk of clinical laid bypass temperature needle vaccination may bring cancer or metastasis.

[0028] 本实用新型真正实现了在肿瘤微波消融治疗过程中,对肿瘤组织的关键部位温度进行实时测量,从而能动地掌控肿瘤微波消融治疗手术,以期达到肿瘤消融的治疗效果和目的,既有利于癌症的治愈和减少对正常细胞不必要损伤,又降低患者疼痛和有利于其术后康复。 [0028] The present invention truly tumor microwave ablation process, the key parts of the temperature of the tumor tissue for real-time measurement, thereby actively control tumor microwave ablation procedure, in order to achieve a therapeutic effect and object of the tumor ablation, both conducive to cancer cure and reduce unnecessary damage to normal cells, but also beneficial to reduce patient pain and postoperative rehabilitation. 同时,为肿瘤微波消融智能化创造了条件,并奠定了硬件方面的技术基础。 Meanwhile, tumor microwave ablation intelligence to create the conditions and technical basis hardware.
