Definitions
- the invention relates to the technical field of medical devices, and in particular to an object ablation system, a control method, a device, a medium and an electronic device.
- Radiofrequency ablation mainly use thermal ablation technologies such as radiofrequency ablation, microwave ablation, cryoablation and focused ultrasound ablation.
- the fundamental principle of radiofrequency ablation is hyperthermia. It uses a high-frequency electromagnetic wave, which is composed of alternating electric fields and magnetic fields. The energy generated by radiofrequency waves of 375kHz to 500kHz forms a closed loop in the human body from the transmitter to the treatment electrode needle through the negative plate. .
- the ions around the electrode needle are excited by the alternating current and collide and rub to form heat. When the heat exceeds the tolerance of the tumor tissue, the tumor cells will undergo coagulative necrosis. The small blood vessels around the tumor will be occluded due to thermal damage, thus blocking the Cut off the blood supply to the tumor.
- the tumor tissue instantly produced a large area of coagulation necrosis, resulting in the complete blurring of the lesion boundary under real-time ultrasound. Therefore, when judging whether ablation is complete, it is difficult to define the distance between the ablation range and the edge of the lesion, and it may cause complications such as skin ecchymosis, skin burns, muscle burns, secondary fat necrosis, and wound infection.
- FMPA focused microwave phased array thermal therapy
- PMC percutaneous microwave thermal coagulation
- Laser ablation mainly inserts a cutting-edge laser fiber into the tumor.
- the thermal effect is generated between the laser photons and the tissue, which increases the tissue temperature and creates a thermal ablation area.
- it may cause permanent damage to the surrounding blood vessels and nerve tissue, and may also cause incomplete ablation. or excessive ablation.
- High-intensity focused ultrasound ablation is a non-invasive ablation technology that does not require minimally invasive placement of catheters or probes at the tumor site.
- HIFU reaches a very high sound intensity at the focus, so that the sound energy is quickly absorbed by the tumor tissue and converted into heat energy, and the local temperature instantly rises to Above 65°C, the protein in the target area will be denatured and the cells will be coagulated and necrotic, while the normal tissue passed by the ultrasound beam and the tissue surrounding the target area will not be damaged or the damage will be very small.
- the target tissue is required to maintain a static state and reduce movement as much as possible. Otherwise, the treatment may be off-target and complete ablation cannot be achieved.
- ablation of an expanded range of tumor edges can achieve radical treatment, the ablation range increases. It also increases the risk of internal tissue damage.
- Cryoablation places a cryoprobe in the center of the tumor to rapidly drop the temperature of the tumor cells below the freezing point.
- the tumor cell membrane is ruptured, the organelles are damaged, and eventually the tumor cells die.
- cells that are not killed by direct cryoinjury may also undergo secondary apoptosis.
- cryoablation may also induce local microvascular destruction and cause blood flow stasis.
- the above ablation principle is mainly to achieve the purpose of tissue cell necrosis through changes in the temperature around the tissue.
- thermal ablation technology can easily cause damage to healthy tissues such as nerves, lymph, and blood vessels in the ablation area.
- some manufacturers use radiofrequency ablation technology to ablate lung diseases, such as chronic bronchitis, by ablating the smooth muscle around the tracheal cartilage to dilate the trachea and increase ventilation.
- this method is also a thermal ablation technology, which uses high temperature to cause cells to expand.
- the protein deteriorates, resulting in tissue necrosis, and it is difficult to control the ablation range, which can easily lead to damage to healthy tissues such as blood vessels and nerves.
- the trachea is mainly supported by cartilage and smooth muscle. Therefore, if the smooth muscle is excessively ablated, this method may easily cause the cartilage to be unable to support it, causing the trachea to collapse, causing more serious consequences.
- Pulsed electric field ablation technology As a non-thermal ablation technology, pulsed electric field ablation technology, which uses irreversible electroporation theory for treatment, has increasingly attracted attention in clinical applications. Pulsed electric field ablation technology generates a high-voltage pulsed electric field with a pulse width of milliseconds, microseconds or even nanoseconds to release extremely high energy in a short period of time, which can cause cell membranes and even intracellular organelles such as endoplasmic reticulum, Mitochondria, cell nuclei, etc. will produce a large number of irreversible micropores. This in turn causes the apoptosis of diseased cells, thereby achieving the desired therapeutic purpose.
- pulsed electric field ablation technology can selectively treat inflammatory cells in the lungs without affecting other non-target cells and tissues. At the same time, it also has the characteristics of thorough full-thickness ablation, precision, speed, and Features of protecting blood vessels, nerves, and cartilage. At the same time, since the pulsed electric field ablation technology is not affected by the heat pool effect, it can perform superimposed ablation multiple times, which can greatly enhance the ablation depth.
- CT imaging technology needs to be used to assist in guiding the ablation head through the bronchial branches to reach the tumor, which will cause the patient and the operator to receive a large amount of radiation.
- CN201580060018.3 It is necessary to mark the tissues near the target first, and position them through fluoroscopy images and CT images. The positioning method is complex and has low accuracy, and a microwave ablation device is used for ablation treatment.
- CN202010113062.9 requires a fusion positioning method that combines a depth camera and a magnetic positioner to locate the ablation needle, but the real-time positioning and visibility are poor.
- CN109788979A uses pulsed electric field ablation technology, but during the intervention and energy delivery process, the exact position of the interventional device in the treatment area cannot be determined, and the control parameters can only be modified based on feedback from the implemented status, resulting in the loss of pulsed energy ablation. Problems include poor accuracy, poor real-time performance, and poor targeting of disease areas.
- US13538947, CN201711006154.1, etc. provide probe-type ablation heads to treat narrow lung tissue. However, the probe-type ablation heads cannot form a good fit with the lesion tissue, and the ablation area is small.

Description
本发明涉及医疗器械技术领域,具体涉及一种对象消融系统、控制方法、装置、介质及电子设备。
现有的消融手段主要采用射频消融、微波消融、冷冻消融和聚焦超声消融等热消融技术。射频消融的根本原理是热疗,是通过一种高频电磁波,由交变电场和磁场组成,以375kHz至500kHz的射频波产生的能量从发射器至治疗电极针经负极板在人体形成闭合回路。电极针周围的离子受到交变电流的激发而发生碰撞、摩擦形成热量,当热量超过肿瘤组织的耐受程度时肿瘤细胞会发生凝固性坏死,肿瘤周围的小血管因为受热损伤而闭塞,从而阻断肿瘤血供。在操作过程中,因为肿瘤组织瞬间产生大面积凝固性坏死,导致实时超声下病变边界完全模糊。因此,在判断是否完全消融时,难以界定消融范围与病灶边缘的距离,且可能引起皮肤瘀斑、皮肤烧伤、肌肉灼伤、续发性脂肪坏死、伤口感染等并发症。
微波消融主要有两种方式:聚焦微波相控阵热疗法(FMPA)和经皮微波热凝固(PMC)。FMPA微波通过组织和细胞内水分子的快速搅动产生介电热,导致热诱导的凝固性坏死。PMC是将可发射微波能量的探针直接插入肿瘤内部,从而可在短时间内产生使蛋白质变性或细胞凝固性坏死的高温。主要作用机理是因为癌细胞的水分高于正常细胞的水分,所以在微波作用下癌细胞会产生更多热从而将细胞凝固性坏死,但仍会有皮肤烧伤的周围组织热损伤的现象发生。
激光消融主要是将尖端激光纤维插入肿瘤中,通过激光光子与组织之间产生热效应,提高组织温度并产生热消融区域,但可能对周围血管和神经组织造成永久损伤,同样也会造成消融不彻底或过度消融的现象。
高强度聚焦超声消融(HIFU)是一种非侵入性无创消融技术,其不需要在肿瘤部位微创放置导管或探针。通过将高能量的超声聚焦,HIFU在焦点处达到很高的声强,使声能迅速被肿瘤组织吸收并转化为热能,局部温度瞬间升高至
65℃以上,使靶区蛋白质变性、细胞凝固性坏死,而超声束经过的正常组织及靶区周围组织不产生损伤或损伤很小。但HIFU治疗过程中要求靶区组织尽可能维持静止状态、减少移动,否则容易造成治疗脱靶,从而不能实现完全消融;其次,虽然对肿瘤边缘扩大范围的消融可实现根治性治疗,但消融范围增加的同时也增加了内组织损伤的风险。
冷冻消融是将冷冻探针置于肿瘤中心,使肿瘤细胞温度迅速下降至冰点以下,在反复冻融的过程中,造成肿瘤细胞膜破裂、细胞器损伤,最终导致肿瘤细胞死亡。但是未被直接冷冻伤致死的细胞也可能继发细胞凋亡,同时冷冻消融还可能诱导局部微血管破坏引起血流淤滞。
以上的消融原理主要是通过组织周围温度的变化达到组织细胞坏死的目的。例如,US14023328、US15099665、CN202011501204.5等。但是当出现热沉效应时,热消融技术很容易导致消融区域的神经、淋巴、血管等健康组织受损。例如,部分厂家通过射频消融技术来消融肺部疾病,比如慢性支气管炎,通过消融气管软骨周围的平滑肌来实现气管扩张,增加通气量的作用,但此方法同样属于热消融技术,通过高温使细胞蛋白质变质,从而实现组织坏死,很难控制消融范围容易导致血管和神经等健康组织受损。而且气管主要是由软骨和平滑肌支撑起来的,因此,假使平滑肌过度消融,该方法还容易造成软骨无法支撑,而使气管塌陷造成更严重的后果。
采用不可逆电穿孔理论进行治疗的脉冲电场消融技术作为一项非热消融技术日渐得到了临床应用的关注。脉冲电场消融技术是通过产生一种脉宽为毫秒、微秒甚至纳秒级的高压脉冲电场,在短时间内释放极高的能量,其能使细胞膜甚至是细胞内的细胞器如内质网、线粒体、细胞核等会产生大量的不可逆的微孔。进而造成病变细胞的凋亡,从而达到预期的治疗目的。在治疗慢阻肺的应用中,采用脉冲电场消融技术可以选择性的处理肺部炎性细胞,而不对其他非靶的细胞组织产生影响,同时其还具有彻底的全层消融、精准、快速、保护血管、神经、软骨的特点。同时脉冲电场消融技术由于不受热池效应的影响,可以多次进行叠加消融,进而能够极大增强消融深度。
在目前的消融治疗中,利用外科手术切开周围组织,使肿瘤完全暴露并进行穿刺消融和切除方式对人体的创伤较大,切口愈合时间长,还伴随着创口感染的风险,因此微创介入治疗已经成为了医学界较为标准的手术方法。在采用
介入方式对目标病灶区域进行活检或消融病灶时,确定介入设备在目标对象体内的位置对于准确实施手术是至关重要的。现有确定介入设备在目标对象体内准确位置的方法包括通过内窥镜图像来观察和运用透视影像来识别。在实际使用过程中,例如,对肺部病灶的治疗,由于肺支气管解剖结构呈现多级分支分叉,仅通过支气管内窥镜的图像无法识别和记录介入设备在支气管内的准确位置,且受限于支气管内窥镜的外径,内窥镜无法到达更为细小的支气管分支,因此无法为介入设备提供图像方面的帮助。在手术过程中,因为透视影像对人体有一定的损害,所以不能一直采用透视影像来观察,而且透视影像对肺支气管的图像并不清晰,因此无法从三维角度确定介入设备在图像中的位置。对于类似肺部支气管的复杂区域的介入治疗,术者在操控介入设备时容易在“复杂分叉”的肺支气管内“迷路”,从而影响了手术的准确性和效率,增加了术者的工作强度。
现有的对肺部疾病的治疗中,例如,CN201810310511.1,需采用CT成像技术来辅助引导消融头穿过支气管分支到达肿瘤,会使患者和术者接受大量射线。CN201580060018.3需先对目标附近的组织进行标记,通过荧光透视图像和CT图像配合定位,定位方法复杂、准确性低,且采用微波消融装置进行消融治疗。CN202010113062.9需采用深度相机和磁定位仪相配合的融合定位的方法定位消融针的位置,定位实时性和可视性差。CN109788979A,采用脉冲电场消融技术,但其在介入和能量输送过程中,并不能确定介入设备在治疗区域内的准确位置,且只能基于已实施状况的反馈进行控制参数修正,致使脉冲能量消融的准确性、实时性差和对病灶区针对性差等问题。US13538947、CN201711006154.1等提供了探针式消融头以对狭窄的肺部区域组织进行治疗,但是探针式消融头不能与病灶组织形成很好的贴合,消融面积较小。
现有的介入设备大多具有体积较大、连接可靠性差、弯曲灵活性差、无法到达更远、更狭窄的支气管分支,且无法与病灶组织很好贴靠,大大影响了手术的准确性、效率和治疗效果,且容易对患者造成损伤的问题。
基于现有技术的缺点,需要提供一种采用微创介入治疗方式,能够在复杂的治疗区域中导航和确定介入器械的准确位置,使介入器械能够精准到达治疗区域与病变组织均匀贴靠,同时采用脉冲电场消融技术生成更精确的脉冲能量对病变组织进行针对性治疗的综合系统。

本申请通过在消融前构建仿真消融模型,使得术者可以直观的观察到基于初始消融参数生成的脉冲能量的消融范围和消融效果,并可以直观的帮助术者判断初始消融参数是否需要调整,进而对初始消融参数和消融次数进行优化,得到目标消融参数,以生成更精确的脉冲能量。
本申请消融设备的开关电路通过不同分支电路的连接和对不同分支电路上对应输入端开关模块和输出端开关模块的控制,可以实现脉冲能量的幅度、脉宽、间隔、数量或方向等的若干种组合。通过对不同分支电路上对应输入端开关模块和输出端开关模块的控制和滤波模块配合,可以实现不同频率和形态的脉冲能量的输出。基于本申请开关电路,消融设备可以通过在一组脉冲能量中具备不同的电压幅度、频率和脉冲形态的变化,生成更针对性的脉冲能量,在增加治疗效果的同时有利于减少在消融治疗过程中带来的刺激反应问题,提高治疗安全性。
本申请导航控制设备还包括消融三维模型生成模块,消融三维模型用于记录介入组件在目标介入区域中的消融轨迹信息和消融数据。通过消融三维模型术者可随时回顾观察介入组件的消融轨迹信息和消融数据,为术者判断哪些部位已经消融,哪些部位仍未消融,提供了非常重要的数据支撑,可有效提高手术效率,降低手术重复消融的可能。

本申请提供一种对象消融系统,能够通过导航定位功能控制介入设备精准的进入肿瘤、管腔、器官等目标介入区域与病变组织形成较好的贴靠,且能够通过在消融前对消融效果数据进行消融效果评估生成更精确和更针对性的脉冲能量并输送至病变组织来进行消融治疗。
本申请对象消融系统可以用于对肺部气管和支气管内病症进行治疗,例如慢性支气管炎、慢性阻塞性肺病、哮喘等。肺部支气管组织结构主要包括上皮细胞、固有层和粘膜底层,其中上皮细胞为具有纤毛的假复层细胞,假复层细胞之间夹有杯状细胞,杯状细胞分泌少量粘液;粘膜底层主要包括平滑肌和结缔组织,位于结缔组织处的粘液腺分泌大部分粘液。长期产生过多的粘液并在肺中积聚,是造成多种肺部疾病的主要病因。本申请对象消融系统能够通过脉冲能量破坏去除上皮细胞中的杯状细胞和粘膜底层中的粘液腺体,从而减少支气管腔中粘液的分泌,并通脉冲能量将失效的长有纤毛的假复层细胞杀死,新生的上皮细胞能更好的帮助气管粘液咳出,防止粘液堆积。本申请对象消融系统能够提高手术准确性、效率、治疗效果和治疗安全性。

在一些实施例中,第二位置采集装置11可以设置在芯轴13或介入组件12上的任意位置,第二位置采集装置11的数量不受限制。第二位置采集装置11
的数量越多,可以更全面的实时定位和呈现介入设备1在气管中的实时变化,从不同维度表达介入设备在气管中的位置。优选地,第二位置采集装置11设置在芯轴13或介入组件12的远端。第二位置采集装置11用于采集介入组件12在目标介入区域中的介入位置信息,并通过信号线传输至导航控制设备2,目标介入区域属于目标对象。在一些可能的实施方式中,第二位置采集装置11可以为磁感应传感器,磁感应传感器可以通过磁场获取介入组件12在目标介入区域中的介入位置信息;在另一些可能的实施方式中,第二位置采集装置11可以为电感应传感器,电感应传感器可以通过电场获取介入组件12在目标介入区域中的介入位置信息。优选地,第二位置采集装置11包括至少一个五自由度磁定位传感器或六自由度磁定位传感器。
需要说明的是,在一些实施例中,芯轴13可以为分别与消融设备4和介入组件12相连接的电极线,用于将消融能量传递到介入组件12上。在另一些实施例中,芯轴13可以为不锈钢弹簧管、海波管或螺旋管等,芯轴13内设有分别与消融设备4和介入组件12相连接的电极线。电极线可以为单股或多股,线径可以为0.05mm-1mm,电极线的材质为可导电的金属材料。在一些实施例中,芯轴13的外层设有聚四氟乙烯涂层或不带涂层。
具体地,操控管组件14包括至少一个与消融电极121连接的操控管141。在一些可能的实施方式中,介入组件12包括一个消融电极121,操控管组件14包括一个操控管141,消融电极121的远端与芯轴13的远端连接,消融电极121的近端与操控管141的外壁固定连接,操控管141的远端与芯轴13的远端相间隔设置。在另一些可能的实施方式中,介入组件12包括第一消融电极122和第二消融电极123,第一消融电极122和第二消融电极123沿芯轴13依次设置,操控管组件14包括依次套设的第一操控管142和第二操控管143,第一消融电极122的远端与芯轴13的远端连接,第一消融电极122的近端与第一操控管142的外壁固定连接,通过控制第一操控管142移动可控制第一消融电极扩张或收缩,第一操控管142的远端与第一消融电极122的远端相间隔设置;第二消融电极123的远端与第一操控管的外壁连接,该外壁距离第一操控管远端一定距离,第二消融电极123的近端与第二操控管143的外壁固定连接,通过控制第二操控管移动可控制第二消融电极扩张或收缩。
如图5所示,在一些可能的实施方式中,介入组件12包括多个消融电极121,
多个消融电极121可张开的最大距离相同。如图11所示,在另一些可能的实施方式中,多个沿芯轴13依次设置的消融电极121可张开的最大距离沿芯轴13远端到近端的方向依次增加。因此,可以根据气管内径的变化,通过操控管组件控制不同直径的消融电极121张开以适应不同内径尺寸的气管。具体地,至少一个消融电极121能够构成为单极电极或双极电极。在一些可能的实施方式中,至少一个消融电极121释放单极脉冲,目标对象体表贴有负极板,通过负极板与产品结合在体内形成回路,使脉冲能量作用在治疗区域。在另一些可能的实施方式中,不同的消融电极121在目标对象体内构成正负两极,正负能量传递,将正负两极以及两极范围内的能量范围形成一个闭环治疗区域。控制最两端消融电极121的电路导通,可以得到更大范围的消融面积,控制相邻两消融电极121的电路导通,可以将消融范围控制在相邻两消融电极121之间,治疗范围更精准,刺激反应更小。
在一些可能的实施方式中,介入组件12包括一个消融电极121,消融电极121通过多条电极线与消融设备中的连接端口电连接,连接端口包括一个负极端口和7个正极端口。负极端口用于连接贴在目标对象体表的负极板,其他7个正极端口分别与不同的电极线连接,电极线与消融电极121连接。例如,第一电极线连接第一端口,第二电极线连接第二端口,第三电极线连接第三端口,第四电极线连接第四端口,第五电极线连接第五端口,第六电极线连接第六端口,第七电极线连接第七端口。每个电极连接端口都可通过用户设置单独控制,且根据消融的区域和范围,控制线路的通断。
在一些实施例中,消融电极121包括多条电极线,多条电极线交叉编织成网状的消融电极121。优选地,消融电极121可以为导电的金属丝编织而成,金属丝的材质优选的可以为不锈钢、镍钛合金、钴铬合金等具有良好导电性能的材料。金属丝的纵切面可以是椭圆形、圆形或多边形,使得编织成的消融电极121可以更充分的与目标位置贴合。网状消融电极121容易改变形状,可以扩张和收缩,网格紧密度、拉伸性能和结构稳定性更高,可以更好的与目标位置贴合,且贴合面积更大、更加均匀,治疗效果更好。
在一些实施例中,如图8-11所示,消融电极121扩张后的轴向截面可以为纺锤形、多边形、椭圆形或伞形。当消融电极121的近端远离其远端时,消融电极121收缩为与芯轴13同轴的圆柱体,以方便在狭窄通道内移动;当通过操
控管带动消融电极121的近端向靠近其远端的方向移动时,消融电极121可以扩张为轴向截面为椭圆形、纺锤形、多边形或伞形的网状体,以增加与不同内径支气管和特殊形状待消融对象的贴合面积。在一些可能的实施方式中,多个消融电极121沿芯轴3依次设置,多个消融电极121可扩张的最大直径沿芯轴13远端到近端的方向依次增加,可根据进入气管的内径控制不同直径的消融电极121张开以适应不同内径尺寸。当气管特别细小时,可仅控制最远端直径最小的消融电极121张开,轴向截面为矩形的圆柱体结构更适合路径平滑的气管。
在一些实施例中,消融电极121的外侧设有绝缘层,绝缘层用于增加消融电极121的绝缘性能。
在一些实施例中,操控管141可以是PI(聚酰亚胺)、PET(聚对苯二甲酸乙二醇酯)、Pebax(嵌段聚醚酰胺树脂)或PTFE(聚四氟乙烯)等挤出管,或者PI/PTFE复合管。操控管141的外径可以优选为0.5mm-5mm,操控管141的壁厚可以优选为0.025mm-0.5mm,长度可以优选为40cm-80cm。

具体地,介入设备1还包括固定套15,固定套15与消融电极121的端部固定连接,以固定消融电极121的端部。固定套15的套体两端沿周向设有内齿结构151,两端内齿结构151均从套体的端面向端面内侧倾斜设置。在一些可能的实施方式中,内齿结构(151)的齿形可以为波浪齿、三角齿、平齿或梯形齿等。
消融电极121的两端通过固定套15与芯轴13或操控管组件14固定连接。固定套15的内齿结构(151)可以更好的固定网状消融电极121,内齿结构(151)的设置使固定套15的两端开口变小,提高了同轴性,大大减小了消融电极121的远端与芯轴13固定后弯扭导致的同轴问题。在一些可能的实施方式中,固定套15的两内齿结构(151)之间可以用于放置第二位置采集装置11,以减小第二位置采集装置11安装所占用的空间。通过固定套15固定消融电极121的两端,提高了消融电极121两端的同轴性和连接可靠性,避免了手术过程中消融电极121的脱落,提高了介入设备的可靠性,缩短了治疗时间,并可以给第二位置采集装置11留有放置空间。
具体地,介入设备1还包括操作柄16,操作柄16内设有能够容纳芯轴13和操控管组件14穿过的通道161。操作柄16为介入设备的控制柄,介入设备的芯轴13和信号线可以集合为一体,从操作柄16的通道161内穿出,结构紧凑,避免了信号线裸露在外的冗余。在一些可能的实施方式中,通道161的近端设有固定卡口162,固定卡口162与芯轴13的近端连接,固定卡口162用于固定芯轴13。固定卡口162的内侧可以设置密封圈163,密封圈163用于提高操作柄16的密封性和导电安全性。在一些实施方式中,操作柄16可以通过塑料、尼龙或硅胶等材料3D打印或注塑而成。操作柄16上设有操控组件17,操控组件17的与操作柄16滑动或转动连接,操控组件17的另一端与操控管组件14的近端固定连接。在一些可能的实施方式中,操控组件17的一端被构造为与操作柄16的外壁滑动连接的滑块,操控组件17的另一端被构造为与操作柄16内壁滑动连接的柱塞部,柱塞部与操控管组件14的近端固定连接。在另一些可能的实施例中,操控组件17可以被构造为旋钮,旋钮内圈与操控管组件14螺纹连接,通过旋钮转动可带动操控管组件轴向移动。本申请通过操控组件17可以控制操控管组件14相对于芯轴13移动,以控制介入组件12的扩张程度。
具体地,介入设备1还包括贴靠检测装置和介电常数检测装置,贴靠检测装置和介电常数检测装置分别与导航控制设备2通信连接。贴靠检测装置用于检测待消融对象的阻抗数据以及介入组件12的贴靠参数。阻抗数据用于指示介入组件12的负载,贴靠参数用于指示介入组件12与待消融对象间的贴靠程度;并发送至初始参数获取模块025;介电常数检测装置用于检测待消融对象的介电常数。在一些实施例中,贴靠检测装置和介电常数检测装置可以设置在介入组
件12的外壁上。

导航规划模块024用于根据介入区域子模型、操作对象三维模型进行导航规划,得到介入组件12在介入区域子模型内的导航路径,导航路径用于指示介入组件12在目标介入区域内抵达待消融对象过程中所需途径的行进路径。
需要说明的是,本申请导航规划模块024可以根据介入区域子模型和操作对象三维模型,对介入组件12在目标介入区域内抵达待消融对象的移动路径进行导航规划,得到介入组件12在介入区域子模型内的导航路径,生成相应的二维、三维和导航数据,同时在导航三维模型内显示规划好的从介入组件入口处到待消融对象的导航路径。在一些可能的实施例中,导航三维模型内可以突出显示出规划好的导航路径的路径关键点,术者可以根据显示的导航路径控制介入组件12在导航三维模型内移动,操控介入组件12抵达待消融对象。
在一些实施例中,导航规划模块024还用于在介入组件12在目标介入区域的运动过程中,基于介入组件12的介入位置信息和运动位置信息确定介入组件12的介入轨迹信息;若介入轨迹信息与导航路径对应的路径轨迹信息满足预设偏差条件,对介入组件12在目标介入区域中的介入位置进行修正,至介入组件12的更新的介入轨迹信息与路径轨迹信息相匹配。

据介入组件12的介入位置信息和运动位置信息可以确定介入组件12的实时介入轨迹信息,根据介入组件12的实时介入轨迹信息生成介入轨迹的轨迹关键点,将轨迹关键点与规划好的导航路径的路径关键点进行动态匹配运算;当轨迹关键点与规划好的导航路径的路径关键点的匹配度满足预设偏差条件时,对介入组件12在目标介入区域中的实时介入位置进行修正,至介入组件12的实时介入轨迹信息与路径轨迹信息相匹配。本申请预设偏差条件为介入轨迹的轨迹关键点与规划好的导航路径的路径关键点之间的偏差是否超过预设偏差阈值,当介入轨迹的轨迹关键点与路径关键点之间的偏差大于预设偏差阈值,则对介入组件12在目标介入区域中的实时介入位置进行修正;当介入轨迹的轨迹关键点与规划好的导航路径的路径关键点之间的偏差小于等于预设偏差阈值,则控制介入组件12沿导航路径继续移动。本申请通过对介入组件12的实时介入轨迹与导航路径的动态匹配可以在介入组件12在目标介入区域的运动过程中随时调整介入组件12的移动方向,避免介入组件12偏移导航路径迷路或对周围健康组织造成伤害,提高导航准确度。
在一些可能的实施方式中,当导航三维模型中出现导航路径相面模糊或被遮挡的情况,术者依旧可以根据所显示的导航三维模型判断路径前方是否为通路,并判断是否继续沿规划好的导航路径运动。例如,肺支气管的导航三维模型内出现相面模糊或被遮挡的情况,通常是支气管通道内的肺部粘液造成的,术者根据显示的导航三维模型可以判断出遮挡前方的支气管为通路时,可以继续向前探索,利用粘液的粘性特质,当介入组件12的前端遇到粘液时,根据导航路径的导向,继续向前输送一段距离,就可以冲出粘液,使得粘液沿着气管壁顺流,而不再贴粘在介入组件12的前端上,从而解决视野模糊受干扰的问题,节约手术时间。
如图26和27所示,导航控制设备2还包括初始参数获取模块025和目标参数确定模块026。

的病变类型和病变程度信息;待消融对象的阻抗数据可以指示介入组件12当前的负载情况;介入组件12的贴靠参数包括且不限于介入组件12与支气管的贴靠面积和接触长度等信息。
本申请根据待消融对象的介电常数可以判断当前待消融对象的组织特性。具体地,不同的细胞有不同的电穿孔阈值,因此不同组织的介电常数不同,通过不同组织的介电常数比例就能指导不同组织占比进而确定组织中不同细胞的含量。在一些可能的实时方式中,介电常数的检测可以利用产生5KHz-300MHz中多个频率的正弦激励信号,激发反应细胞组织在不同频率信号下所对应的复阻抗电信号的变化,然后将这些信号通过如傅里叶变换等方法转换成频域的信号,从而得到组织的介电常数。本申请根据消融前和消融后的待消融对象的介电常数的对比,可以了解待消融对象对应的支气管组织中不同种类细胞的含量的变化,从而可以帮助评估消融参数的有效程度。
目标参数确定模块026用于根据导航三维模型、操作对象三维模型、待消融对象的对象属性信息、待消融对象的对象属性信息所对应的初始消融参数、待消融对象的阻抗数据、介入组件12的贴靠参数和待消融对象的介电常数进行消融效果评估,得到初始消融参数对应的消融效果数据;若消融效果数据满足目标消融条件,将初始消融参数确定为目标消融参数。
如图28是本申请脉冲能量对肺部消融效果的仿真、评估及显示的原理图。
需要说明的是,本申请阻抗数据与脉冲电压、脉冲宽度、脉冲时间和脉冲频率等参数一起,可以计算出当前加载到待消融对象的脉冲能量。通过阻抗的变化率可以得到介入组件12的贴靠参数,从而判断出介入组件12与待消融对象的贴靠质量。在一些可能的实施方式中,通过介入组件12的贴靠参数可以计算出支气管的内壁直径,从而判断支气管粘膜层的厚度。如图29所示为支气管的内径与接触长度的关系,当介入组件12的型号和规格不变,介入组件12与支气管的接触长度随着支气管的内径增加而减小。进一步地,根据阻抗数据可通过仿真进一步得到支气管内径、消融范围、贴靠参数、脉冲参数和支气管厚度与消融效果之间的关系。例如,在一些实施方式中,如图30所示,选取支气管内壁接触处中央深度大约0.5mm处点作为表征消融效果的标记点,当介入组件12与支气管的接触长度为5.0mm、7.5mm、10.0mm、12.5mm和15.0mm时,对应的场强分别大约为1220V/cm、1120V/cm、900V/cm、1000V/cm和
1125V/cm,当接触长度大约为11.0mm时场强最小,大约为900V/cm,随着支气管级数增加、内径减小,介入组件12与支气管的接触长度增加,标记点处场强有减小趋势,但最小场强不小于900V/cm,可以满足达到预设的消融效果时的阈值场强,治疗效果没有显著降低。如图31所示,选取支气管内壁接触处中央深度大约0.5mm处点作为表征消融效果的标记点,随着支气管壁厚增加,当介入组件12与支气管的接触长度为5.0mm、7.5mm、10.0mm、12.5mm和15.0mm时,对应的场强分别大约为1600V/cm、1310V/cm、1120V/cm、1060V/cm、1080V/cm和1200V/cm,当接触长度大约为10.0mm时场强最小,大约为1060V/cm,随着支气管壁厚增加,介入组件12与支气管的接触长度增加,标记点处场强有减小趋势,但最小场强不小于1000V/cm,可以满足达到预设的消融效果时的阈值场强。很明显,本申请中,当支气管内径减小或者支气管壁厚增加时,增加介入组件12与支气管的接触长度,并不会对消融效果产生较大的影响。
具体地,目标参数确定模块026包括仿真消融模型构建单元0261。
仿真消融模型构建单元0261用于基于对象属性信息、初始消融参数、阻抗数据、贴靠参数、介电常数、操作对象三维模型和导航三维模型作为消融评估模型的输入,进行消融效果仿真,得到初始消融参数对应的仿真消融模型,仿真消融模型用于表征初始消融参数对应的消融效果数据。
需要说明的是,仿真消融模型构建单元0261将对象属性信息、初始消融参数、阻抗数据、贴靠参数、介电常数、操作对象三维模型和导航三维模型一起输入到消融评估模型中进行消融效果仿真,得到初始消融参数对应的仿真消融模型。本申请消融评估模型可以是通过预先仿真的数据以及临床收集的数据建立的消融评估数据库。预先仿真的数据为根据阻抗数据仿真得到的支气管内径、消融范围、贴靠参数、脉冲参数和支气管厚度与消融效果之间的关系数据。本申请根据仿真消融模型可以直观的观察到基于初始消融参数生成的脉冲能量对肺部组织的消融范围和消融效果,并可以直观的帮助术者判断初始消融参数是否需要调整。如图32所示,设置脉冲电压幅度为1500V时生成的仿真消融模型中脉冲能量对肺部组织的消融效果,可以看出支气管中绝大部分区域被消融。
在一些实施例中,在仿真消融模型中可以通过消融模型的颜色区分指示基于不同初始消融参数对肺部组织的消融范围和消融效果,术者就可以根据仿真消融模型,调整初始消融参数,也可以以此来规避可能的风险。如图33本申请
支气管组织的病理结构图,如图34所示的仿真模型中可以看出对不同初始消融参数预测生成的脉冲能量对支气管组织黏膜层的浅表消融、部分消融和完全消融的消融效果。
需要说明的是,当得到的初始消融参数对应的消融效果数据满足目标消融条件后,则将该初始消融参数确定为目标消融参数。在一些可能的实施例中,目标消融条件包括通过仿真消融模型观察到的肺部组织消融范围和消融效果达到需要消融的效果,且消融后待消融对象的介电常数满足预设条件,即消融后支气管组织中不同种类细胞的含量达到正常组织标准。
需要说明的是,本申请可以在消融前将对象属性信息、初始消融参数、阻抗数据、贴靠参数、介电常数、操作对象三维模型和导航三维模型一起输入到消融评估模型中进行消融效果仿真,得到仿真消融模型,以根据仿真消融模型对消融前的消融效果提前进行指示,进而对初始消融参数和消融次数进行优化,从而提高治疗的有效性。在另一些实施例中,还可以在消融后将更新的对象属性信息、消融参数、阻抗数据、贴靠参数、介电常数、操作对象三维模型和导航三维模型一起输入到消融评估模型中进行消融后的效果仿真,从而帮助判断是否消融有效。对消融后的消融效果进行消融效果评估还可以用于优化消融评估数据库,帮助优化和学习,以此提高评估的质量。

本申请对象消融系统、控制方法、装置、介质及电子设备中还提供一种脉冲消融效果评估方法及装置可以应用于肺部组织的消融治疗。但本申请并不限定于此,本申请实施例提供的技术方案还可以对其他身体部位,例如胃部,进行消融。下文中以肺部消融为例,对本申请实施例进行说明。
图38是本申请实施例提供的脉冲消融效果评估方法的一个流程图,如图38所示,本申请实施提供的脉冲消融效果评估方法可以包括如下步骤:
S110:对消融导管处的当前组织进行标测建模,得到当前组织的三维模型;
本申请实施例将三维导航系统和内窥镜配合使用。通过三维导航系统在手术过程中对肺部支气管进行建模,构建当前进行手术时肺部模型,术者可以从导航界面上观察到肺部的整体支气管结构和走向。同时通过内窥镜可以直观的观察到肺部支气管的位置和内部情况。如此,既能观察到肺部的整体支气管结构和走向,又能观察到肺部支气管的位置和内部情况,与现有技术相比能够更全面的了解肺部的情况。
另外本申请实施例还配合了预测和消融导航的功能,医生可以通过输入初始参数,通过导管配合内窥镜进入肺部,导管根据输入的参数和当前的气管厚度和位置预测出消融的深度和范围,呈现给医生,供医生参考和调整参数。
图39是本申请实施例提供的脉冲消融效果评估系统的连接框图,如图39所示,消融导管分别通过脉冲输出回路和电极回路与脉冲电场消融装置连接,脉冲电场消融装置分别通过通信回路和电极回路与三维导航系统连接,消融导管与患者之间通过耗材连接。
图40是本申请实施例提供的脉冲消融效果评估方法的原理框图,具体的如图40所示,三维导航系统通过磁定位采集数据。消融导管通过阻抗/贴靠检测确定当前组织的阻抗以及导管的贴靠状态,通过网篮的张开和贴靠范围来判断组织的内壁直径,并且通过采集介电常数判断当前的组织特性。介电常数得到的信息就可以得到对应组织的一些特性,因为不同的细胞有不同的电穿孔阈值,进而可以用于评估消融的能量是否能够达到要求。
消融导管将采集到的阻抗、介电常数和网篮数据传输给脉冲电场消融系统,与脉冲电场消融系统所设置的消融参数一起输入消融状态评估模型中进行计算;
三维导航系统能够与脉冲消融装置进行数据交互;三维导航系统能够生成消融效果评估所需的当前组织的三维模型,这里的当前组织可以是肺部支气管组织。
S120:获取待评估数据;
具体的,待评估数据包括消融导管采集的检测数据、消融装置的消融参数和网篮状态数据;
具体地,消融参数包括脉冲电压、脉冲宽度、脉冲个数和脉冲组数中的一个或多个。
具体地,网篮状态数据包括网篮张开状态数据和网篮与当前组织的贴靠面积,网篮张开状态数据和贴靠面积用于确定待消融区域的厚度。通过网篮张开的大小和贴靠面积可以确定支气管内壁的直径(即支气管的内径,而非支气管的外径,支气管的外径是含软骨的),从而得到支气管粘膜层的厚度,这里的待消融区域就是粘膜层这部分区域。
肺部支气管组织结构:支气管主要分为:上皮细胞(有纤毛的假复层,假复层之间夹着杯状细胞,杯状细胞分泌少量粘液);固有层(基底膜和松散的结缔组织同上皮细胞和固有层一起,构成了粘膜);粘膜底层(平滑肌&更多的结缔组织)。而位于结缔组织处的粘液腺就是分泌大部分粘液的地方,在对肺部进行消融等场景下,脉冲消融对象主要是消融粘膜层中的粘液腺体和杯状细胞。
S130:将待评估数据输入预先训练好的消融状态评估模型,得到消融状态评估结果;消融状态评估模型能够根据待评估数据和待评估数据与消融状态的对应关系,计算出待评估数据对应的消融状态评估结果;消融状态评估结果包括消融范围、消融深度和消融有效程度。
在一些可能的实施例中,可以通过对比消融前后的介电常数来判断消融有效程度,因为电穿孔下不同细胞组织的阈值是不一样的,通过了解支气管组织中不同种类细胞的含量可以帮助评估消融的参数的有效程度。
肺部消融主要是消融支气管粘膜层中的异常组织(如杯状细胞和粘液腺),所以通过仿真数据、阻抗/贴靠数据,介电参数,配合当前设定的消融参数,输入消融状态评估模型,可以对消融效果进行有效的评估。
其中,仿真数据为根据阻抗数据仿真得到的支气管内径、消融范围、贴靠参数、脉冲参数和支气管厚度与消融效果之间的关系数据。
评估过程可以是在消融前,这样就可以对消融前的效果提前进行指示,进而指导术者消融的参数以及次数。当然也可以在消融后,这样术者可以帮助判断是否消融有效。而且消融后,可以通过重新的标测评估,判定消融的范围和效果以此来进行优化,从而提高治疗的有效性。
S140:在当前组织的三维模型中展示消融状态评估结果。
当消融前的标测建模完成,需要评估的数据也一并获悉,就可以在三维系统中基于图33所示的支气管病理结构图,通过消融模型的颜色区分指示消融参数后消融的评估,得到如图34所示的消融范围预测图,术者就可以根据模型一目了然,可以以此优化消融数据,也可以以此来规避可能的风险。
在一个实施例中,将待评估数据输入预先训练好的消融状态评估模型,得到消融状态评估结果之后,包括:
将待评估数据和消融状态评估结果保存到样本数据中,得到更新后的样本数据;
基于更新后的样本数据训练并更新消融状态评估模型。
消融状态评估模型可以在每次消融后对消融后进行不停的优化和学习,因为反馈的作用范围,阻抗贴靠信息,介电参数,消融参数在脉冲消融后都会有一定的更新,可以以此优化消融状态评估模型,以此提高评估的质量。
在一个实施例中,将待评估数据输入预先训练好的消融状态评估模型之前,包括:
获取样本数据;其中,样本数据可以是通过预先仿真得到的包括待评估数据、消融状态以及待评估数据与消融状态的对应关系的数据,也可以是临床收集的包括待评估数据、消融状态以及待评估数据与消融状态的对应关系的数据;还可以是仿真数据与临床收集的数据的组合,如此可以增加样本的数量,降低收集样本数据的工作量。
使用样本数据训练预先构建的机器学习模型,并在训练过程中调整机器学习模型的参数,直至机器学习模型输出的消融状态评估结果满足要求;将机器学习模型保存为消融状态评估模型。
当然,这个模型训练的过程可以在三维导航系统通过导管进行导航标测建模的过程中一并完成。
消融状态评估模型可以是机器学习模型,具体为神经网络模型。图41是本
申请实施例提供的消融状态评估模型的一个示例,如图41所示,在一个实施例中,消融状态评估模型以全神经网络(例如Tensorflow)作为主要算法,选择Encode与Decode作为神经网络机器学习框架,选用Sigmold,Relu和Softmax三种函数作为各层网络的激活函数,神经网络模型选用全连接神经网络,共五层:网络结构共分四种:输入层,隐藏层,Dropout层,输出层;整个神经网络分别选用sigmold,relu和softmax三种函数作为各层网络的激活函数。损失函数为交叉熵。参数优化方法有两种AdamOptimizer和GradientDescentOptimizer,学习率为1e-4。模型输入与输出是(1*4)对应(1*4)。
在一个实施例中,在当前组织的三维模型中展示消融状态评估结果,包括:
根据消融状态评估结果以及消融状态评估结果与展示颜色的对应关系确定消融状态评估结果对应的展示颜色;优选的,不同消融状态对应不同的展示颜色,如此可以直观的反映各区域的消融状态。消融状态与展示颜色的对应关系优选为以图例的形式进行展示。
在当前组织的三维模型中显示消融状态评估结果和/或消融状态对应的展示颜色;消融状态评估结果包括消融范围、消融深度和消融有效程度。
如图32所示,消融的效果可以通过不同的颜色深浅变化来表示,从而让医生直观的观察到肺部组织消融的范围和效果,并可以直观的帮助医生判断消融参数是否需要调整。
具体地,检测数据包括阻抗信号,获取待评估数据,包括:
向消融导管的电极加载第一信号;第一信号的频率范围为第一预设频率范围;第一预设频率范围优选为2KHz到200KHz;
采集第一信号作用在电极后的回传信号;
对回传信号进行滤波处理以将回传信号转化为阻抗信号。
其中,阻抗检测方法可以采用分时切换检测、融合提取检测、分频切换检测中的一种或多种。
这里,阻抗信号可以指示当前的负载情况,阻抗信号与消融参数如脉冲电压,脉冲宽度,脉冲个数,脉冲组数等参数一起,就可以计算出当前加载到组织的能量。而贴靠质量和面积也可以通过阻抗的变化率进行判断。贴靠面积大小可以决定消融的质量。
具体地,检测数据包括介电常数信号,获取待评估数据,包括:
将正弦激励信号通过消融导管的电极作用于当前组织;正弦激励信号的频率范围为第二预设频率范围;第二预设频率范围优选为5KHz□300MHz。
获取不同频率正弦激励信号作用于当前组织后回传的复阻抗电信号,将复阻抗电信号作为介电常数信号。
介电常数的检测利用的是产生5KHz-300MHz中多个频率的正弦激励信号,激发反应细胞组织在不同频率信号下所对应的复阻抗电信号的变化。而这些信号通过小波变换、傅里叶变化等方法转换成频域的信号。不同组织参数的介电常数是不一样的,通过不同的介电常数比例就能指导不同组织的占比进而确定细胞的含量。因为电穿孔下不同细胞组织的阈值是不一样的,通过了解支气管组织中不同种类细胞的含量可以帮助评估消融的参数的有效程度。
支气管的内径与产品接触长度的关系可通过实验获得。根据该数据,可通过仿真进一步得到待评估数据与消融状态的对应关系,待评估数据与消融状态的对应关系优选为消融状态、贴靠数据、脉冲参数、支气管厚度之间的关系,具体的,消融状态包括消融范围和消融深度。
