 附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1为本申请一实施例提供的动态调整射频参数的方法的应用场景示意图；
图2为本申请一实施例提供的动态调整射频参数的方法的流程示意图；
图3为本申请另一实施例提供的动态调整射频参数的方法的流程示意图；
图4为本申请一实施例提供的动态调整射频参数的装置的结构示意图；
图5为本申请一实施例提供的射频主机的结构示意图。
 本发明的实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参见图1，本申请一实施例提供的动态调整射频参数的方法的应用场景示意图，该动态调整射频参数的方法可用于在射频操作过程中，通过检测射频数据，对比该射频数据与当前操作阶段对应的标准范围和极限范围，确认射频操作是否出现问题，从而对出现问题的射频操作进行干涉，使得射频操作能够继续顺利进行，对严重问题及时中止，提高射频操作的安全性。
具体地，该方法的执行主体为射频主机，射频主机具体可以是射频消融仪等设备。如图1所示，射频主机100与注射泵200连接，射频主机100与注射泵200也与操作对象300连接，射频操作开始，射频主机100通过射频发生装置向操作对象300发送射频能量，射频100控制注射泵200向操作对象300注射用于降温的液体。射频主机100中设置有操作对象300进行射频操作的初期、中期、后期等各阶段射频数据标准范围和极限范围，在射频操作过程中，随着操作对象300的性状改变，在其上作用的射频数据也会发生改变。
进一步地，射频数据标准范围和极限范围都可以是一个数值范围，包括最大值和最小值，若操作对象300的实时射频数据大于该标准范围的最大值或小于该最小值，都可通过控制注射泵的注射量，使得射频数据位于该标准范围内，控制注射量可通过控制注射流速实现；若操作对象300的实时射频数据大于该极限范围的最大值或小于该最小值，则确认射频主机100或操作对象300出现问题，须停止射频操作；射频数据标准范围和极限范围还可以是射频数据的变化率，即斜率，在预设检测时长内，实时射频数据形成过大的斜率，超出预设的斜率，则同样通过调整注射泵的注射量达到调整射频数据的目的，或者停止射频操作，排除故障，提高射频操作的安全性。
参见图2，本申请一实施例提供的动态调整射频参数的方法的流程示意图。该方法可应用于图1所示的射频主机，如图2所示，该方法具体包括：
步骤S201、确认射频操作当前所处的操作阶段，并获取与射频操作的操作对象和该操作阶段对应的射频数据标准范围和射频数据极限范围；
射频数据标准范围位于射频数据极限范围之内，即，射频数据标准范围的最小值大于射频数据极限范围的最小值，射频数据标准范围的最高值大于射频数据极限范围的最高值；
具体地，操作对象类型不同，或者，同一类型的操作对象的个体差异，射频数据标准范围都会不同；同一操作对象的不同射频操作阶段，射频数据标准范围和射频数据极限范围也不同。操作对象可以是进行射频操作的任意物体，例如在射频消融时，操作对象可以是生物体的异常组织，通过消融消除或缩小该异常组织。
在射频主机中内置有具体的操作对象不同操作阶段的射频数据标准范围和射频数据极限范围的信息，可供射频主机的检测装置读取这些信息，并根据实时检测的当前射频操作的操作对象和操作阶段的射频数据，分别与该射频数据标准范围和射频数据极限范围进行对比。
步骤S202、实时检测该操作对象的射频数据，并将该射频数据分别与该射频数据标准范围和该射频数据极限范围进行对比；
射频操作作用在该操作对象上会生成射频数据，具体可包括阻抗值、温度值、电流值和电压值等，射频主机实时检测该操作对象的上述射频数据，这些射频数据反馈当前射频操作的是否正常。
步骤S203、若实时检测到的射频数据超出该射频数据标准范围但未超出该射频数据极限范围，且持续预设时长，则控制注射泵对该操作对象的注射量，以将射频数据控制在该射频数据标准范围内；
当检测到该检测对象在现操作阶段的射频数据，超出该射频数据标准范围持续达预设时长时，通过控制注射泵的注射量调整射频数据达到正常的标准范围，进一步排除偶然因素造成的射频数据不稳定，提高检测的智能性。
步骤S204、若实时检测到的射频数据超出该射频数据极限范围，则停止射频能量输出。
若实时检测到的射频数据超出该射频数据标准范围，表示射频操作出了严重问题，为了保护射频主机和操作对象的安全，及时停止射频能量的输出，具体可以是检测模块将射频数据发送给射频主机的处理器，由该处理器向射频主机的射频信号发生装置发送停止信号，令该射频信号发生装置停止输出射频信号。
本申请实施例中，获取与射频操作的操作对象和当前操作阶段对应的射频数据标准范围，将实时检测的射频数据分别与射频数据标准范围和射频数据极限范围进行对比，若实时检测到的射频数据超出该射频数据标准范围但没有超出该射频数据极限范围，且持续了预设时长，则通过控制注射泵对操作对象的注射量，来控制射频数据位于该射频数据标准范围内，实现对射频数据在该射频数据标准范围内的动态调整，提高射频操作的成功率，若实时检测到的射频数据超出该射频数据极限范围，则确认当前射频操作的射频主机或操作对象出现问题，则停止射频能量输出，避免射频主机和操作对象受到损害，提高射频操作的安全性。
参见图3，本发明另一实施例提供的动态调整射频参数的方法的实现流程图。该方法可应用于图1所示的射频主机，如图3所示，该方法具体包括：
步骤S301、设置阻抗值标准范围和阻抗值极限范围；
响应于用户的设置操作，显示阻抗值的最低值、最高值以及变化率的输入界面，设置操作可以是用户输入，也可以是根据用户指令从射频主机的存储器或与射频主机连接的服务器的数据库中调取。
获取该用户设置的阻抗值的第一最低值、第一最高值和第一变化率，将该用户输入的第一最低值和第一最高值作为该标准数值区间的最低值和最高值，以及，将该用户输入的第一变化率作为该标准斜率；
获取该用户设置的阻抗值的第二最低值、第二最高值和第二变化率，将该用户输入的第二最低值和第二最高值作为该极限数值区间的最低值和最高值，以及，将该用户设置的第二变化率作为该标准斜率。
其中，第一最低值高于第二最低值，第一最高值低于第二最低值，第一变化率低于第二变化率，变化率低表示在单位时间里数值变化小。
具体的阻抗值的设置与射频主机的型号、射频操作的任务和操作对象的性质、射频操作在操作对象上的操作位置相对应，这种对应关系是已知的，可由用户输入或从射频主机或服务器等相关设备中预先存储。
步骤S302、在进行射频操作之前，检测操作对象的阻抗值是否超出预设初始值范围的最高值，若超出，则控制注射泵向操作对象注射液体以降低阻抗值；
若检测到的操作对象的阻抗值高于预设初始值范围的最高值，则控制注射泵向操作对象注射液体以降低操作对象的阻抗值，直至阻抗值符合该预设初始值范围。即，在射频操作开始之前，令操作对象的初始阻抗值位于正常的初始值范围内，以减少射频操作开始后由于初始阻抗值偏离正常范围，而对射频操作过程中基于该阻抗值的检测、判断产生影响。
该初始值范围是与操作对象的性质以及射频操作在该操作对象上的具体位置对应的，是根据对多个操作对象的实际测量值得到的一个普遍范围。例如，射频操作为射频消融时，操作对象为人体，具体位置为肺部组织，则该初始值范围为250-350Ω（欧姆）。
步骤S303、确认射频操作当前所处的操作阶段，并获取与射频操作的操作对象和该操作阶段对应的阻抗值标准范围和阻抗值极限范围；
该阻抗值标准范围可以是阻抗值的标准数值区间，该标准数值区间为包括最低值和最高值的数值区间。在射频操作过程中，该阻抗值标准范围优选地为150-500Ω，或者，按照该操作对象的性质设置的标准斜率，即在射频操作过程中该操作对象的阻抗值最小不低于150Ω，最大不超过500Ω的前提下，根据该操作对象的性质确认一个无需调整的阻抗值的标准变化率，低于该标准变化率的实时的阻抗值的变化率对于该操作对象是不需要调整的，该标准变化率即为该标准斜率。
该阻抗值极限范围可以是阻抗值的极限数值区间，该极限数值区间为包括最低值和最高值的数值区间，在射频操作过程中，该阻抗值极限范围优选地为50-600Ω，或者，按照该操作对象的性质设置的极限斜率，即在射频操作过程中该操作对象的阻抗值最小不低于50Ω，最大不超过600Ω的前提下，根据该操作对象的性质确认一个安全的阻抗值的极限变化率，低于该极限变化率的实时的阻抗值的变化率对于该操作对象是安全的，该极限变化率即为该极限斜率。
该阻抗值的标准数值区间、标准斜率、极限数值区间和极限斜率的具体数值与该操作对象以及射频操作进行的操作阶段相关，不作具体限定。
步骤S304、实时检测该操作对象的阻抗值，并将检测的该阻抗值分别与阻抗值标准范围和阻抗值极限范围进行对比；
通过阻抗检测电路可直接检测该操作对象的阻抗值，或者，通过电流检测电路检测该操作对象的电流值，并通过电压检测电路检测该操作对象的电压值，根据电流值、电压值与阻抗值的计算公式，计算得到该操作对象的阻抗值。
将实时检测到的阻抗值，与该操作对象的当前操作阶段对应的阻抗值的标准数值区间和/或阻抗值的标准斜率进行实时对比，以及，将该操作对象的当前操作阶段对应的阻抗值的极限数值区间和/或阻抗值的极限斜率进行实时对比。
步骤S305、若实时检测到的阻抗值超出该阻抗值标准范围但未超出该射频数据极限范围，且持续预设时长，则通过控制注射泵对操作对象的注射量，将该操作对象过的阻抗值控制在该射频数据标准范围内；
具体地，若实时检测到的该操作对象的阻抗值低于该标准数值区间的最低值，和/或，该操作对象的阻抗值的降低率大于该第一标准斜率，且持续该预设时长，则控制注射泵按预设的第一注射量减少向该操作对象注射的液体量；
该操作对象的阻抗值低于该标准数值区间的最低值且持续该预设时长，以及，该操作对象的阻抗值的降低率大于该第一标准斜率且持续该预设时长，这两种情况出现任意一种或同时出现，表明该操作对象的阻抗值过低或降低的过于迅速，需要提高阻抗值，因此减少注射泵对该操作对象的注射量，可以通过控制液体的注射流速来控制注射量，固定时长内，流速越大注射量越大。
若实时检测到的该操作对象的阻抗值高于该标准数值区间的最高值，和/或，该操作对象的阻抗值的升高率大于该第二标准斜率，且持续该预设时长，则控制注射泵按预设的第二注射量增加向该操作对象注射的液体量。
该操作对象的阻抗值高于该标准数值区间的最高值且持续该预设时长，以及，该操作对象的阻抗值的升高率大于该第二标准斜率且持续该预设时长，
这两种情况出现任意一种或同时出现，表明该操作对象的阻抗值过高或升高的过于迅速，需要降低阻抗值，因此增加注射泵对该操作对象的注射量。
进一步地，可能会出现偶然原因导致阻抗值的变化，为了避免因频繁调整阻抗值造成注射泵工作过程不稳定，影响射频操作效果，可等待持续该预设时长后，排除偶然因素，启动动态调整该操作对象阻抗值的步骤。
若通过控制注射泵对操作对象的注射量，经过一个预设的调整时长后，仍无法将该操作对象过的阻抗值控制在该射频数据标准范围内，则停止射频操作。
步骤S306、若实时检测到的阻抗值超出该阻抗值极限范围，则停止射频能量输出。
具体地，阻抗值的极限斜率包括用于表示阻抗值降低率的第一极限斜率和用于表示阻抗值升高率的第二极限斜率，极限数值区间、第一极限斜率和第二极限斜率在性质上为极限异常值，即实时检测的该操作对象的阻抗值不论在哪个操作阶段，只要满足如下第一条件中的至少一个条件，都须立即停止向该操作对象输出射频能量，第一条件可包括：阻抗值高于该极限数值区间的最大值，阻抗值低于该极限数值区间的最小值，阻抗值的降低率大于该第一极限斜率，以及，阻抗值的升高率大于该第二极限斜率。其中，阻抗值的降低率是该操作对象的阻抗值在单位时长的降低量与该单位时长的比值；阻抗值的升高率是该操作对象的阻抗值在单位时长的升高量与该单位时长的比值。
进一步地，在停止向该操作对象输出射频能量的同时，进行文字提示和声光告警。具体地，当实时检测到的该操作对象的阻抗值低于该极限数值区间的最低值，或，实时检测到的该操作对象的阻抗值的降低率大于该第一极限斜率，显示第一文字提示并进行声光报警；
当实时检测到的该操作对象的阻抗值高于该极限数值区间的最高值，或，实时检测到的该操作对象的阻抗值的升高率大于该第一极限斜率，显示第二文字提示并进行声光报警。
第一文字提示例如在射频主机的显示屏上显示“LLL”字样，第二文字提示例如在射频主机的显示屏上显示“HHH”字样，声光告警包括声响和闪光两方面的报警。
进一步地，在检测到该操作对象的阻抗值超过上述非极限异常值时，可进行文字提示和声光告警，具体可以是与上述该操作对象的阻抗值超过极限异常值时的文字提示内容不同，声响和闪光的形式也不同，加以与上述告警形式区分。
进一步地，在检测到该操作对象的阻抗值超过上述非极限异常值且持续该预设时长后，停止向该操作对象输出射频能量的同时，进行文字提示和声光告警，此时的文字提示和声光告警与上述该操作对象的阻抗值超过极限异常值时的文字提示内容相同，声响和闪光的形式也相同。
进一步地，若检测的操作对象的阻抗值超出该射频数据标准范围，则将操作对象的阻抗值与射频操作时间的对应关系，以第一颜色的线条形式显示在显示界面上；若检测的操作对象的阻抗值未超出该射频数据标准范围，则将操作对象的阻抗值与射频操作时间的对应关系，以第二颜色的线条形式显示在该显示界面上。
其中，该第一颜色的反射率高于该第二颜色的反射率，反射率越大光线越耀眼，对人眼的提醒度越高。例如，红色对光线的反射是67%，黄色反射是65%，绿色是47%，青色是36%。第一颜色可以是红色或黄色，第二颜色可以是绿色或青色。
以上各步骤的技术细节，参见前述图2所示实施例的描述，此处不再赘述。
本申请实施例中，在进行射频操作之前，将操作对象的阻抗值通过注射泵注射液体的方式降低到正常的初始值范围内，提高后续射频操作时对阻抗值检测的准确度，提高射频操作的成功率，获取与射频操作的操作对象和当前操作阶段对应的阻抗值的标准数值区间和阻抗值变化的标准斜率，将实时检测的操作对象的阻抗值与该标准数值区间和/或标准斜率，以及该极限数值区间和/或极限斜率实时进行对比，则通过控制注射泵对操作对象的注射量，来控制射频数据位于该射频数据标准范围内，实现对射频数据在该射频数据标准范围内的动态调整，提高射频操作的成功率，若实时检测到的该操作对象的阻抗值超出该极限数值区间和/或阻抗值的变化大于该极限斜率，则确认当前射频操作的射频主机或操作对象出现问题，并停止射频能量输出，避免射频主机和操作对象受到损害，提高射频操作的安全性，同时进行文字提示和声光预警，进一步提醒射频操作者注意射频操作的安全性。
