本实施例提供一种复合型能量转换装置，属于医疗器械领域，最常见是用于医疗外科治疗领域超声手术刀的电声转换装置。该复合型能量转换装置，使用时安装在执行器械上，在手术过程中，实现了复合型能量(例如高频能量和超声能量)在同一个执行器械上转换传输，便于医护人员在使用执行器械时迅速地选择进行相应的组织处理(例如凝血或者切割)，有效提升手术效率和成功率，造福患者。
具体参见图1-图17，该复合型能量转换装置，包括基于压电陶瓷62的超声振动子6、用于固定超声振动子6的胶圈及外壳本体、用于实现开关信号转接的换能PCB板5和电缆固定部。
本实施例中，具体参见图1，该复合型能量转换装置(高频及超声复合)通过螺杆64旋于超声执行器械上，以实现高频及超声复合能量的输出；该复合型能量转换装置通过换能PCB板5的信号接收部实现接收来自执行器械的三路开关信号，再通过电缆插头组件103和六芯输入电缆线实现三路开关信号从超声执行器械到超声发生器的传输；超声发生器再通过电缆插头组件103和六芯输入电缆线来将其三路高频电信号输送至超声执行器械。
具体参见图2、图7、图8和图9，换能PCB板5通过在PCB板体51的正面设置两两对称(保证可靠的电性连接)的六个弹性柱53(信号接收部)实现接收来自执行器械的三路开关信号(比如连接三线式开关)，并通过在换能PCB板5的背面所设的导线焊接点56-1/56-2/56-3焊接的导线52中的三根(连接端52-1/52-2/52-3)以及六芯输入电缆线中的三根输入电缆线将开关信号传送给超声发生器；换能PCB板5的中心圆孔部分焊接有铜套55(信号输出部)，该铜套55与换能PCB板5背面所设的焊盘和导线焊接点56-4焊接的另一根导线52(连接端52-4)相连接，该根导线52与六芯输入电缆线中的另一根输入电缆线连接，该铜套55可通过连接导电片以连接执行器械，实现接收来自超声发生器的高频电信号并传送给执行器械(超声执行器械)。
具体参见图2和图10，振动子6穿设固定于外壳本体的一端，该振动子6包括压电陶瓷62和变幅杆63，压电陶瓷62由陶瓷固定块61支撑并同轴固定于变幅杆63上，压电陶瓷62的两电极分别与六芯输入电缆线中的剩余两根输入电缆线连接，且压电陶瓷62容纳 在外壳本体内且与外壳本体的内壁面之间开设足够大的间隙，便于输入电缆线的连接和便于振动子6的安装，变幅杆63的一端通过螺杆64与执行器械的刀杆连接。
具体地，超声发生器根据开关信号控制能量的输出切换，其中，超声发生器连接压电陶瓷62的两电极，对执行器械输出第一能量，超声发生器连接压电陶瓷62的一电极和信号输出部，对执行器械输出第二能量。
具体地，以高频及超声复合能量的换能作为例子说明，换能PCB板5设置弹性柱53接收来自执行器械的超声开关信号，并通过导线52和输入电缆线将开关信号传送给超声发生器，超声发生器(含控制器)将高频电信号通过电缆插头组件103和输入电缆线施加到压电陶瓷62的两电极，激励压电陶瓷62产生超声振动，并通过振动子6的变幅杆63传送给执行器械的刀杆(第二执行部)，以使刀杆随着超声振动实现组织切割功能。
进一步地，换能PCB板5设置弹性柱53接收来自执行器械的高频开关信号，并通过导线52和输入电缆线将开关信号传送给超声发生器，超声发生器将一路高频电流经振动子6其一电极传递给执行器械的刀杆，同时将一路高频电流经换能PCB板5上的铜套55(信号输出部)传递给执行器械的外鞘和钳头(第一执行部)，高频能量分别作用于刀杆和钳头，形成两极间的高频电流，通过刀头与钳头之间的高频放电以实现组织凝血功能。
另外，本实施例中，具体参见图2、图3、图4和图6，外壳本体包括第一外壳1、第二外壳2和第三外壳4，具体地，第一外壳1与第二外壳2的结合部设有一凹槽，内装O形圈9，第二外壳2与第三外壳4的结合部也设有一凹槽，内装O形圈9，O形圈9的作用是防水和增加摩擦，保证第一外壳1与第二外壳2、第二外壳2与第三外壳4之间的连接稳定性。
本实施例中，具体参见图3，第一外壳1沿中心线依次设有护套孔11、环形槽12和螺纹孔13，护套孔11和环形槽12用于穿过电缆护套101，电缆护套101的头部装入环形槽12中，再将电缆固定块102旋入与螺纹孔13螺纹连接，以防止其轴向窜动。
本实施例中，具体参见图15和图16，电缆固定块102通过外螺纹1021旋接于第一外壳1的尾端内，电缆固定块102设有中心孔1022，侧前端设有侧孔1023，前端有胶钉孔1024和一字槽1025或十字槽或梅花槽或其他槽。具体地，该复合型能量转换装置通过电缆插头组件103与超声发生器连接，输入电缆线穿过电缆护套101后经中心孔1022穿入，折弯从侧孔1023穿出，穿出后从电缆固定块102和第一外壳1的内壁间隙往前伸，形成了输入电缆线的二次弯折，以上结构设计使得输入电缆线不易松动和在外壳内扭转；胶钉孔1024的作用在于可以拧入一颗胶钉以进一步固定输入电缆线，防止输入电缆线产生松 动；一字槽1025的作用在于用一字螺丝刀旋动电缆固定块102以便于旋接于第一外壳1的尾端内，实现压紧电缆护套101的端面，防止电缆护套101产生松动。
本实施例中，一对哈夫块3插入第二外壳2的端部，哈夫块3后端台阶面与第二外壳2前端面接触连接，哈夫块3的前端还设有容纳异形胶圈8的包围结构，具体地，哈夫块3的中部设有一凸起31，装配时哈夫块3的凸起31卡入第二外壳2的缺口23内，可限制哈夫块3的绕轴转动，此外，一对哈夫块3之间留有一定的间隙32，方便导线52穿过。
本实施例中，具体参见图2与图10，振动子6在靠近螺杆64的一端设有法兰盘65，法兰盘65的前端面通过平胶圈7与第三外壳4(设有凹槽)接触，法兰盘65的后端面通过异形胶圈8与哈夫块3接触，第三外壳4和哈夫块3通过挤压平胶圈7和异形胶圈8以保证振动子6的轴向位置固定，且使得振动子6的压电陶瓷62容纳在第二外壳内且与第二外壳的内壁面之间有足够大的间隙，便于输入电缆线的连接和振动子6安装，具体地，振动子6在安装时，输入电缆线先连接压电陶瓷62两电极，再将第二外壳2连接到第一外壳1，即是振动子6可以从第二外壳的左端部穿入，再将一对哈夫块3卡入第二外壳2，再安装异形胶圈8，最后将装好平胶圈7的第三外壳4连接到第二外壳2；另外，因平胶圈7和异形胶圈8所受到的压紧力而产生的端面摩擦力足以保证振动子6不会发生绕轴旋转运动。进一步地，振动子6上的法兰盘65一端设有若干个凹槽，异形胶圈8对应设有若干个与上述凹槽匹配连接的凸起，装配时，凹槽与凸起配合连接可阻止振动子6与异形胶圈8绕轴相对旋转。
具体地，参见图2、图6和图7，第三外壳4的前端部设有两个内螺纹柱42，用于结合固定孔54和螺钉等螺纹件固定换能PCB板5，第三外壳4的前端部还设有一过线孔41，以方便导线52穿过。此外，在第二外壳2的前端外周面上设有相邻的第一环形配合面21和第一台阶部201，第三外壳4的前端部的内壁面设有一环形槽以容纳平胶圈7，第三外壳4的内周面的后端部设有相邻的第二环形配合面43和第二台阶部403，第二环形配合面43可与第一环形配合面21过渡配合，具体参见图17，装配时，按照第一环形配合面21与第二环形配合面43的配合将第三外壳4压入第二外壳2，两配合面在压力作用下顺利压入，当第三外壳4的的第二环形配合面43刚好越过第二外壳2的第一环形配合面21时，即是装配到位，此时，胶圈已被压紧，第一台阶部201抵接第二台阶部43,可有效防止第二外壳2与第三外壳4之间产生轴向移动，保证第二外壳2与第三外壳4之间的稳定连接和振动子6的安装稳定性。
以上实施例仅用以说明本发明的技术方案而非限制，参照较佳实施例对本发明进行了 详细说明，本领域技术人员应当理解，对本发明的技术方案进行修改或者等同替换，而不脱离本技术方案的宗旨和范围的方案，均应涵盖在本发明的权利要求范围内。
