Description

向外科器械输出驱动信号的设备 技术领域
本公开涉及用于执行外科手术的超声电外科系统，更具体地，涉及一种向外科器械输出驱动信号的设备。
 背景技术
超声外科器械（简称超声刀）和高频电外科器械（简称电刀）均可用于外科手术。超声刀具有较好的切割性能，但在外科手术中的凝血性能较差。电刀根据工作模式分为单极电刀和双极电刀，双极电刀具有很好的凝血性能，但是在外科手术中的切割性能较差。在超声刀的端部执行器上设置电极后，可实现超声刀和双极电刀的功效，这种多功能的超声外科器械被称为“超声电刀”。

根据本公开实施例，超声能量电路板124上设有至少一个跨越第一网电区和第一应用区的第一元件，在第一元件位于第一网电区的引脚和位于第一应用区的引脚之间的位置，超声能量电路板124上设有第一缝隙。该第一元件其位于第一网电区的引脚和位于第一应用区的引脚之间的电气间隙已满足设计要求，本公开实施例在该两个引脚之间设置第一缝隙，可以进一步增大爬电距离，减小介质电极化的风险。上述两个引脚是超声能量电路板124上距离最近的两个引脚，在保证上述两个引脚安全的情况下，第一网电区的其他引脚与第一应用区的其他引脚之间必然也是安全的。
根据本公开实施例，高频电能量电路板上设有至少一个跨越所述第二网电区和所述第二应用区的第二元件，在第二元件位于第二网电区的引脚和位于第二应用区的引脚之间的位置，高频电能量电路板上设有第二缝隙。该第二元件其位于第二网电区的引脚和位于第二应用区的引脚之间的电气间隙已满足设计要求，本公开实施例在该两个引脚之间设置第二缝隙，可以进一步增大爬电距离，减小介质电极化的风险。上述两个引脚是高频电能量电路板上距离最近的两个引脚，在保证上述两个引脚安全的情况下，第二网电区的其他引脚与第二应用区的其他引脚之间必然也是安全的。
根据本公开实施例，超声能量电路板124上设有超声频率调节模块和超声功率调节模块，用于调节超声信号发生器输出的信号的频率和功率。高频电能量电路板上设有高频电频率调节模块和高频电功率调节模块，用于调节高频电信号发生器输出的信号的频率和功率。主板123可以用于对超声驱动信号和高频电驱动信号进行自适应控制，以便自适应地调整以下至少一种：所述超声驱动信号的功率、所述超声驱动信号的频率、所述高频电驱动信号的功率以及所述高频电驱动信号的频率。
根据本公开实施例，设备100可以采集并处理超声驱动信号和高频电驱动信号，例如通过超声能量电路板124和高频电能量电路板上的专用电路进行采集并处理，得到的信号传输到主板123上。主板123可以基于该信号确定调整参数，基于调整参数控制超声能量电路板124和高频电能量电路板的输出。例如，在使用超声电刀切割肝脏时，超声刀杆的振动可实现切割的功能，电钳口所施加高频电能可辅助进行凝血，当检测到阻抗增大时，驱动超声刀的信号功率也增加，从而加速超声刀杆振动，阻抗变大时，施加在电钳口的信号功率也增加，可提高凝血或者蒸发水分的效率，这样使用超声电刀，可加快切割进程并且减少出血，获得更佳的手术效果。又例如，切割小肠时，由于组织韧性大，切割耗时较多，当使用超声电刀时，就可增加驱动超声刀的信号功率，加速切割，而施加在电钳口的信号功率保持适当水平以蒸发组织内的水分，辅助切割即可。
根据本公开实施例的技术方案，通过对超声驱动信号和高频电驱动信号进行自适应控制，能够更好地匹配手术进程，有利于实现凝血效果和切割性能俱佳的手术效果。
根据本公开实施例，所述超声能量电路板上设有超声信号采集电路，包括第一滤波模块、第一差分放大模块、第二滤波模块、第一自动增益控制模块以及第一模数转换模块，用于采集并处理超声能量电路板与外科器械的连接电路中的信号，以得到超声反馈信号，将所述超声反馈信号提供给所述主板，所述超声反馈信号包括超声电压反馈信号和超声电流反馈信号。
其中，第一滤波模块用于对采集到的超声信号进行初级滤波；第一差分放大模块用于对经过初级滤波后的信号进行差分放大；第二滤波模块用于对经过差分放大后的信号进行次级滤波；第一自动增益控制模块用于对经过次级滤波的信号进行增益控制以便于进行数字采样；第一模数转换模块用于对经过处理后的信号进行数字转换。
根据本公开实施例，所述高频电能量电路板上设有高频电采集电路，包括第三滤波模块、第二差分放大模块、第四滤波模块、第二自动增益控制模块以及第二模数转换模块，用于采集并处理高频电能量电路板与所述外科器械的连接电路中的信号，以得到高频电反馈信号，将所述高频电反馈信号提供给所述主板，所述高频电反馈信号包括高频电压反馈信号和高频电流反馈信号。
其中，第三滤波模块用于对采集到的高频电信号进行初级滤波；第二差分放大模块用于对经过初级滤波后的信号进行差分放大；第四滤波模块用于对经过差分放大后的信号进行次级滤波；第二自动增益控制模块用于对经过次级滤波的信号进行增益控制以便于进行数字采样；第二模数转换模块用于对经过处理后的信号进行数字转换。
根据本公开实施例，主板123用于基于超声反馈信号和高频电反馈信号控制所述输出参数，从而能够更好地匹配手术进程，有利于实现凝血效果和切割性能俱佳的手术效果；同时，通过各自独立的采集和处理电路获取超声反馈信号和高频电反馈信号以便主板123对信号自适应控制，这种结构可降低超声信号和高频信号间的干扰。
根据本公开实施例，所述主板123还用于基于所述超声反馈信号获得声阻抗，基于所述高频电反馈信号获得电阻抗，将所述声阻抗和/或电阻抗与阻抗数据匹配确定组织类型，基于所述组织类型确定所述超声驱动信号的功率和所述高频电驱动信号的功率。
本领域技术人员知晓，由电压信号V(t)和电流信号I(t)，可以得到负载电路中的阻抗，即R(t)=V(t)/I(t)。在本公开实施例中，通过超声能量电路板输出的电压信号和负载电路中的电流信号可得到超声电路中的阻抗R US(t)，简称声阻抗，通过高频电能量电路板输出的电压信号和电流信号可得到高频电路中的阻抗R ES(t)，简称电阻抗。
根据本公开的实施例，声阻抗、电阻抗与负载电路有关，即，与正在切割的组织的阻抗特性有关。如上文所述，可以通过检测手术切割进程中的声阻抗和/或电阻抗，或者其变化规律，来识别切割组织类型，作为调整驱动信号功率的一个依据，实现驱动信号的功率自适应调整，获得更佳的手术效果。
例如，可以在切割初始阶段内设定一个识别组织类型的时间窗，将检测到的声阻抗和/或电阻抗与不同类型组织的阻抗特性值进行对比，匹配度最高的为识别出的组织类型。由于不同组织的物理特性差异其在切割时也会有阻抗差异，通过对实验数据和经验数据的处理和分析，可以得到不同类型的组织在切割初始阶段的区别的声阻抗和/或电阻抗，这些结果可以被存储，并用于匹配组织类型。
示例性地，在切割初始阶段，识别出的组织类型编号为1型，其对应的后一时刻的超声驱动信号的功率P1(n+1)和高频电驱动信号的功率P2(n+1)与前一时刻的声阻抗R US(n)和电阻抗R ES(n)的关系分别为：
P1(n+1) = f1(R US(n), R ES(n))，
P2(n+1) = f2(R US(n), R ES(n))，
如果识别出的组织类型编号为2型，其对应的后一时刻的超声驱动信号的功率P1(n+1)和高频电驱动信号的功率P2(n+1)与前一时刻的声阻抗R US(n)和电阻抗R ES(n)的关系分别为：
P1(n+1)= f3(R US(n), R ES(n))，
P2(n+1)= f4(R US(n), R ES(n))。
其中，f1、f2、f3、f4为函数，例如可以是经验函数或经过训练的神经网络模型；R US(n)、R ES(n)分别为n时刻的声阻抗和电阻抗。采用本公开的实施例，在手术切割中遇到不同的组织时，也可以自动调整更适合该组织的切割功率，提高切割的性能。
根据本公开实施例，主板123还用于基于所述超声电压反馈信号和所述超声电流反馈信号获得第一相位差；基于所述高频电压反馈信号和所述高频电流反馈信号获得第二相位差；基于所述组织类型、所述第一相位差以及所述第二相位差确定所述超声驱动信号的功率和所述高频电驱动信号的功率。
根据负载电路中的电压信号和电流信号的相位差，可以对施加在负载电路中的信号功率进行精准的调整。例如，加载在外科器械上的实际信号功率为 P=UIcos θ，当电压信号和电流信号的相位差θ不为零时，实际信号的功率会降低。根据本公开的实施例，当根据阻抗匹配了组织类型后，如果当前电路中的相位差不为零，则需提高能量源输出的信号功率，从而确保实际加载在外科器械上的信号功率满足要求。例如，当前匹配的组织类型为1型，对应的超声信号的功率建议值为P01，高频电信号的功率建议值为P02，而此时计算得到的第一相位差θ 1，即超声反馈信号的相位差不为零，而第二相位差θ 2为零，则主板123控制超声能量电路板输出的信号功率P US = P 1 / cosθ 1，高频电能量电路板的输出信号功率为P ES=P 2。
根据本公开实施例，主板123还可以对超声能量电路板和所述高频电能量电路板输出信号的时长进行控制。例如，应用超声电刀进行手术切割时，在某时段内，控制超声能量电路板输出驱动信号，而高频电能量电路板不输出，此时超声电刀只执行“超声刀”的切割功能，在另一时段内，控制高频电能量电路板输出驱动信号，而超声能量电路板不输出，此时超声电刀只执行“电刀”的凝血功能，这样也有助于获得更佳的手术效果。
根据本公开实施例，主板123用于基于所述超声反馈信号和/或所述高频电反馈信号确定切割阶段，并基于所述切割阶段确定所述超声驱动信号的功率和所述高频电驱动信号的功率。
根据本公开的实施例，切割的进程可以划分为切割初始阶段、切割进行阶段和切割末期阶段。在每个阶段调整驱动信号功率以适配切割进程可对切割带来益处。例如，在切割初始阶段，要让超声刀快速开始工作，此时驱动超声刀的功率可以较高值输出，而电刀的功率只需较低值；到切割进行阶段，刀头已经深入组织，需要切割并同步凝血，此时要利用超声刀和电刀各自的优势，因此驱动信号功率按各自总功率的50%输出；到切割末期阶段，即将完成切割，充分利用超声刀的快切优势，此时驱动超声刀的信号功率也以较高值输出，而驱动电刀的信号功率只需较低值。
根据本公开的实施例，可通过声阻抗和或电阻抗确定切割阶段，从而在不同的切割阶段输出适配的超声驱动信号和高频电驱动信号。实验发现，切割的阶段也会通过组织的阻抗特性表现出来，例如，在切割刚开始时阻抗先增大后减小，此为切割初始阶段，然后出现较为长期且恒定的一个阶段，此为切割进行阶段，到最后切割末期阶段时，阻抗会快速增加。因此，在检测到声阻抗或电阻抗在设定的时间窗内呈现先下降后平稳的情况下，可识别为进入切割进行阶段，检测到声阻抗或电阻抗在设定的时间窗内呈现快速上升的变化趋势，则识别为进入切割末期阶段。
根据本公开实施例，可以设置在切割初始和切割末期阶段采用固定功率，而在切割进行阶段采用动态调整的功率。可选地，在切割初始阶段，驱动超声刀和电刀的信号功率可依据超声功率设定值和高频电功率设定值来进行比例输出；在切割进行阶段，驱动超声刀和电刀的信号功率可根据声阻抗和/或电阻抗进行自适应调整；在切割末期阶段，驱动信号的功率仍依据超声功率设定值和高频电功率设定值来进行比例输出。这样可以提高功率适配效率，获得更佳的手术效果。
根据本公开实施例，如图1、图2、图5、图7所示，壳体上设有显示屏114，设备100还包括显示电路板127，设置在显示屏114的后方，用于处理显示信号，使显示屏114显示信息。通过显示屏，可以使用户更加直观地了解设备100的状态。

根据本公开实施例，如图1和图2所示，壳体上设有接口115，包括单极电刀正极接口1151、单极电刀负极接口1152、双极电刀接口1153和超声电刀接口1154中的一种或多种。
在单极电刀的工作模式下，可以使用单极电刀正极接口1151和单极电刀负极接口1152与单极电刀连接，向其提供高频电驱动信号，此时，电源模组、主板和高频电能量电路板等组件工作，超声能量电路板可以不工作。
在双极电刀的工作模式下，可以使用双极电刀接口1153与双极电刀连接，向其提供高频电驱动信号，此时，电源模组、主板和高频电能量电路板等组件工作，超声能量电路板可以不工作。
在超声电刀的工作模式下，可以使用超声电刀接口1154与超声电刀连接，向其提供超声驱动信号和/或高频电驱动信号，此时，电源模组、主板、超声能量电路板和高频电能量电路板等组件均工作。其中，如果仅使用超声刀的功能，高频电能量电路板可以不工作。在仅使用超声刀的功能的情况下，设备100可以同时接入单极电刀或双极电刀中的一种，以驱动单极电刀或双极电刀中的一个与超声刀同时工作。

根据本公开实施例，如图3和图5所示，壳体上可以设有多个风扇1171、1172，例如可以设置在背板上。多个风扇中的两个风扇方向相反，至少包括一个向内侧吹风的风扇和一个向外侧吹风的风扇，形成稳定的气流，从而有效提升设备的散热效率。
