Description

用于组织凝结的装置
技术领域
本发明涉及医学领域，用于医院和医疗中心中手术期间的组织凝结。
在先技术
有一种公知的激光组织凝结器(参见B.Pyer的“使用激光刀和电子刀的腔内手术器械”，莫斯科，Meditsina，1996，77-78页)，由一个串联的光电放大器和探测器构成，其中光电放大器的控制输入与有效电量控制输入连接。有效电量根据事先调整的参数可变。
这种凝结器的问题是，当在完成凝结处理后坏死深度增加时，由于不再控制光电转换器的有效电量，而产生大面积坏死。
有一种公知的电子组织凝结器(参见B.Pyer的“使用激光刀和电子刀的腔内手术器械”，莫斯科，Meditsina，1996，115页)，由一个串联的高压电源、有效电量调节器和探测器构成，其中光电放大器的控制输入与有效电量控制输入连接。
对于上述凝结器，有效电量根据事先调整的参数可变，因此当在完成凝结处理后坏死深度增加时，由于不再控制光电转换器的有效电量，可能产生深度坏死。
发明概述
本发明的目的在于发明一种可以降低组织坏死深度的组织凝结器。
由于这种可自动调节有效电量的凝结器的发明，这一问题利用本发明可以得到解决。通过将一种压电式变压器引入该装置这成为可能，该压电式变压器的电源输入连接于电量调节器的输出，并且控制输入连接于直流电源，而输出连接于探测器。施加于组织的电量的控制因压电式变压器的共振频率转为较小或较大值而自动进行。在凝结器操作的开始阶段，共振频率“向左”转移，按0.5-0.6％变为较小值。这一事实使得在开始阶段降低有效电量以防止或至少降低操作该设备时外科大夫的手的颤抖的影响成为可能。凝结处理时，在血管结合阶段，组织抗力增加，导致共振频率“向右”转移，变为较大值，其结果是有效电量增加。当出现坏死作用时，组织抗力急剧下降，导致压电式变压器的共振频率“向右”急剧转移，其结果是电压自动从探测器移走。
附图简述
图1表示本发明所述的组织凝结装置的结构布置图；
图2表示操作该装置期间压电式变压器的频率特征曲线的变化。
本发明最佳实施方式
所述装置包括一个高压电源1，电量调节器2，压电式变压器3和探测器4。
最大值为300-500V，频率与压电式变压器3的共振频率一致的正弦曲线信号(曲线6，图2上的点10)，从高压电源1的输入传送到有效电量调节器2的输入(电源基于手术类型选择并且为10-60mW)，然后，该信号到达压电式变压器3的输入，在这里它的电压被放大到1-5kW。在开始阶段，100-120V的电压从恒压汇流条5施于压电式变压器3的控制输入。这将压电式变压器的共振频率按0.5-0.6％左移(图2中的曲线7)，其结果是有效电量(压电式变压器的输出电压U)被降低一些(图2中的点9)。在血管结合阶段的凝结过程中，探测器4输出部分的等效组织抗力增加。这就导致由于共振频率右移(图2中的曲线6)使得有效电量的增加(图2上的点10)。当出现坏死作用时，随之出现的是组织抗力急剧降低，等效组织抗力急剧下降，并且压电式变压器的共振频率急剧右移(图2中的曲线8)，这样电压降低到对应于曲线8上的点11处的值。
本申请的装置相对于公知的组织凝结器使得可极大地降低坏死深度成为可能。
这样，对于肝部手术，利用改进质量的凝结器，坏死深度从公知装置的50-40微米降低至本申请的装置的10微米。
对于胫骨手术，利用改进质量的凝结器，坏死深度从200-150微米降低20微米。
