Translated fromChinese技术领域technical field
本发明涉及医疗器械技术领域，更加具体来说，本发明涉及一种无绳超声刀换能器。The present invention relates to the technical field of medical devices, and more particularly, to a cordless ultrasonic blade transducer.
背景技术Background technique
超声刀的原理是利用超声波换能器产生振动，发出的超声波沿着刀杆的纵向轴线传播，然后在刀杆上沿轴线产生振幅放大的振动，最后在刀头端部产生高速纵向机械运动，刀头末端的机械振动在切割软组织时非常有效，并且由超声高频振动产生的热可以凝结组织，闭合血管。这种器械由于刀杆通过套管可以易于到达手术部位，特别适用于微创手术，如内窥镜或腹腔镜手术。超声刀控制的关键是沿着刀杆长度产生共振的同时控制刀头的振动幅度，从而在手术过程中获得最佳性能。但是，生成有效的驱动信号颇具挑战性，例如施加在换能器上的频率，电流和电压必须全部动态控制，因为这些参数随着刀头上负载的变化以及刀杆产生的温差而变化。这些因素导致超声刀的控制系统是一个相对复杂的带处理器的模拟数字混合的电路，并且在处理器上运行有实时控制软件和人机交互软件。由于对控制系统的要求较高，目前市场上大部分超声刀产品均为有绳产品，例如强生公司的Harmonic系列，使用时需要将超声刀连接到一个台式发生器。这种设计在应用上的缺点是连接导线导致手术中有所牵扯，使用不便。现有的有绳换能器长度为92.8mm，重量为40.96g。长度长、重量大，使用较笨重。The principle of the ultrasonic knife is to use the ultrasonic transducer to generate vibration, the ultrasonic wave transmitted along the longitudinal axis of the tool bar, and then the amplitude-amplified vibration is generated on the tool bar along the axis, and finally the high-speed longitudinal mechanical motion is generated at the end of the tool head. The mechanical vibration of the tip of the cutter head is very effective in cutting soft tissue, and the heat generated by the ultrasonic high-frequency vibration can coagulate the tissue and close the blood vessels. Since the blade can easily reach the surgical site through the cannula, this instrument is especially suitable for minimally invasive surgery, such as endoscopic or laparoscopic surgery. The key to ultrasonic knife control is to control the vibration amplitude of the knife head while resonating along the length of the knife shank for optimal performance during surgery. However, generating an effective drive signal is challenging, as the frequency, current, and voltage applied to the transducer must all be dynamically controlled, as these parameters vary with the load on the tool tip and the temperature difference created by the tool shank. These factors cause the control system of the ultrasonic knife to be a relatively complex analog-digital hybrid circuit with a processor, and real-time control software and human-computer interaction software run on the processor. Due to the high requirements on the control system, most of the ultrasonic scalpel products on the market are corded products, such as the Harmonic series of Johnson & Johnson, which requires connecting the ultrasound scalpel to a desktop generator. The disadvantage of this design in application is that the connecting wire leads to some involvement in the operation, which is inconvenient to use. The existing corded transducer is 92.8mm long and weighs 40.96g. The length is long, the weight is heavy, and it is cumbersome to use.
因此，无绳超声刀应运而生，使得整个超声刀不需要连接台式发生器就可独立工作，医生使用中不再受后面的导线困扰。无绳超声刀由于其便捷、高效而受到青睐。正因为便携，重量、体积以及工作效率成为无绳超声刀的重要指标。Therefore, the cordless ultrasonic knife came into being, so that the whole ultrasonic knife can work independently without connecting the desktop generator, and the doctor is no longer troubled by the wires behind it. Cordless ultrasonic scalpels are favored for their convenience and efficiency. Because of its portability, weight, volume and work efficiency have become important indicators of the cordless ultrasonic knife.
无绳超声刀主要由换能器、刀头、外壳、电路板以及电池构成，这些主要组成部分也决定了无绳超声刀的重量、体积以及效率。换能器无疑是无绳超声刀的重要组成部分，换能器对无绳超声刀的重量以及效率产生重要影响。但现有的无绳超声刀，换能器存在体积大、重量重的问题，不利于携带和使用。The cordless ultrasonic knife is mainly composed of a transducer, a cutter head, a casing, a circuit board and a battery. These main components also determine the weight, volume and efficiency of the cordless ultrasonic knife. The transducer is undoubtedly an important part of the cordless ultrasonic knife, and the transducer has an important impact on the weight and efficiency of the cordless ultrasonic knife. However, in the existing cordless ultrasonic knife, the transducer has the problems of large volume and heavy weight, which is not conducive to portability and use.

具体实施方式Detailed ways
下面结合说明书附图对本发明提供的无绳超声刀换能器进行详细的解释和说明。The cordless ultrasonic knife transducer provided by the present invention will be explained and described in detail below with reference to the accompanying drawings.
本实施例具体公开了一种无绳超声刀换能器，如图1所示，换能器为半波长结构，包括前金属块1、压电晶堆2、后金属块3和预紧螺钉4，前金属块1和后金属块3均为铝合金块，预紧螺钉4为钛合金螺钉，能保证力学性能的同时减轻换能器的重量。前金属块1呈阶梯状，前金属块1内部沿轴线设有螺纹孔11，螺纹孔11贯穿前金属块1，即螺纹孔11为通孔，阶梯状的前金属块1结构减轻换能器重量的同时减小换能器的体积，螺纹孔11进一步减轻换能器的重量。后金属块3、压电晶堆2和前金属块1依次同轴套设在预紧螺钉4的钉杆上，预紧螺钉4的钉杆与前金属块1的螺纹孔11螺纹连接，后金属块3和压电晶堆2被压紧在预紧螺钉4的钉头和前金属块1之间，前金属块1的较小端部远离压电晶堆2。预紧螺钉4的钉头外径大于钉杆的外径，钉头的前端面与后金属块3的后端面贴合，后金属块3的前端面与压电晶堆2的后端面贴合，压电晶堆2的前端面与前金属块1的后端面贴合，即与前金属块1的较大端面贴合。通过预紧螺钉4的钉头和前金属块1产生均匀的夹持力，压力均匀传递给后金属块3和压电晶堆2，使超声换能器的压电晶堆2能够获得均匀的压力分布，从而有效提高换能器的机电转换效率，实现超声换能器的低阻抗、高输出的性能。This embodiment specifically discloses a cordless ultrasonic knife transducer. As shown in FIG. 1 , the transducer is a half-wavelength structure, including a front metal block 1 , a
当后金属块3、压电晶堆2和前金属块1依次套设于预紧螺钉4的钉杆上时，前金属块1通过螺纹孔11的螺纹连接在钉杆上，且前金属块1的后端面紧密贴在压电晶堆2上时，钉头受力，并将该应力传递给后金属块3和压电晶堆2，压电晶堆2受到均匀的压力，当压电晶堆2连接上具有与超声换能器相同频率的高频电信号时，压电晶堆2内的压电陶瓷片被激发，从而促使超声换能器产生高频谐振，将电能转化为机械能。When the
在另一实施例中，前金属块1的较大端部还同轴连接有法兰部5，法兰部5的法兰面与压电晶堆2抵接，法兰部5的法兰面的面积大于前金属块1较大端部的面积，更好地将压力均匀地传递给压电晶堆2。优选的，法兰部5为铝合金结构，法兰部5与前金属块1一体成型，保证换能器的力学性能、减轻换能器的重量。In another embodiment, the larger end of the front metal block 1 is also coaxially connected with a
如图1和2所示，前金属块1呈二级阶梯状，包括沿远离压电晶堆2方向依次连接的第一过渡段12、第一平直段13、第二过渡段14和第二平直段15，第一过渡段12的外径和第二过渡段14的外径沿远离压电晶堆2方向逐渐减小，第一平直段13的外径与第一过渡段12的最小外径相同，第二平直段15的外径与第二过渡段14的最小外径相同。第一平直段13和第二平直段15的外周面均为直圆柱面，第一过渡段12和第二过渡段14实现平滑过渡，外径逐渐减小，减小体积和重量的同时振动幅度逐渐增大。二级阶梯状的前金属块1使得前金属块1的直径得到二次逐渐减少，保证前金属块1的力学强度，同时受到压电晶堆2传递过来的振动时的振动幅度更大。As shown in FIGS. 1 and 2 , the front metal block 1 is in a two-stage stepped shape, and includes a
前金属块1也可以为三级阶梯状结构或四级阶梯状结构，只要能保证力学强度和声学性能即可。由于更多级的阶梯结构相对于二级阶梯状结构，虽然重量减少，但力学性能减弱，因此，前金属块优选为二级阶梯状结构。The front metal block 1 may also have a three-level stepped structure or a four-level stepped structure, as long as the mechanical strength and acoustic performance can be guaranteed. Compared with the second-level stepped structure, the weight of the more-level stepped structure is reduced, but the mechanical properties are weakened. Therefore, the front metal block is preferably a two-level stepped structure.
在本实施例中，法兰部5的外径与第一过渡段12的最大外径的比例为7：6，法兰部5与第一平直段13的外径比为2:1，第一平直段13与第二平直段15的外径比为3:2，该外径比能充分保证换能器的力学强度和声学性能。In this embodiment, the ratio of the outer diameter of the
第一过渡段12和第二过渡段14的外周面为弧形面，保证力学强度和声学性能。The outer peripheral surfaces of the
在本实施例中，螺纹孔11为阶梯孔，阶梯孔的台阶面与第一平直段13与第二过渡段14的连接面平齐，或者位于第一平直段13的内部。螺纹孔11设置为阶梯孔，在保证力学强度和声学效果的同时，减轻超声换能器的重量。预紧螺钉4的钉杆可与螺纹孔11的较大部分或较小部分中的任一部分螺纹连接，只要实现预紧效果即可。In this embodiment, the threaded
后金属块3与预紧螺钉4的钉头接触的端面边缘设置倒角或倒圆角，使得对后金属块3周面的直径做适度的递增结构，近似形成为带一过渡台阶的圆环面，从而使得后金属块3能够更好的接收到预紧螺钉4的钉头的预紧力同时，进一步改善超声换能器的谐振特性。后金属块3的前端面(即与压电晶堆2的接触面)为平整的圆环面。The edge of the end face of the
在本实施例中，换能器的整体长度为51.4mm，该长度的减少是借助于前金属块结构的改进以及前金属块和后金属块材质的选择实现的，在减轻重量、减小体积、保证力学强度和声学效果的同时，减少整体长度。In this embodiment, the overall length of the transducer is 51.4 mm, and the reduction of the length is achieved by means of the improvement of the structure of the front metal block and the selection of the materials of the front metal block and the rear metal block. , While ensuring the mechanical strength and acoustic effect, the overall length is reduced.
将本实施例的具有法兰部5的无绳超声刀换能器与现有的有绳换能器的长度和重量进行对比，如下表1所示。本实施例的压电晶堆2的外径、后金属块3的外径和预紧螺钉4钉头的外径与现有有绳超声换能器的均相同，现有有绳超声换能器的前金属块材质为铝合金、后金属块材质为不锈钢、预紧螺钉材质为钛合金，现有有绳超声换能器前金属块的外径与本实施例的第一过渡段12的最大外径相同。本实施例中，法兰部5的外径为18mm，第一过渡段12的最大外径为15.4mm，第一平直段13的外径为9mm，第二平直段15的外径为6mm。法兰部5的长度为2mm，第一过渡段12的长度为2.5mm，第一平直段13的长度为10mm，第二过渡段14的长度为2mm，第二平直段15的长度为14mm，压电晶堆2的长度为10.2mm，后金属块3的长度为6mm，预紧螺钉4的钉头长度为4.7mm。The length and weight of the cordless ultrasonic blade transducer with the

The reduction ratio is 36.99%. The cordless ultrasonic knife transducer of this embodiment is greatly reduced in volume and weight, which is convenient to carry and use, and improves the use effect.

The acoustic characteristics of the existing corded transducer and the cordless ultrasonic blade transducer of this embodiment are compared, as shown in Table 2.
表2Table 2
对比表2数据可以看出，本实施例的无绳超声刀换能器的声学特性得到提升，相位容限几乎增加了一倍。换能器在谐振点附近相位容限的增加将更利于换能器与主机的匹配，提高系统的工作效率。Comparing the data in Table 2, it can be seen that the acoustic characteristics of the cordless ultrasonic knife transducer of this embodiment are improved, and the phase tolerance is almost doubled. The increase of the phase tolerance of the transducer near the resonance point will be more conducive to the matching between the transducer and the host, and improve the working efficiency of the system.
综上，本发明的无绳超声刀换能器为半波长结构，前金属块为阶梯状结构，重量减轻，更便于携带；且满足力学性能的同时提升了声学特性，换能器在谐振点的相位容限增加将近一倍，更利于换能器与主机的匹配，提高系统的工作效率。To sum up, the cordless ultrasonic knife transducer of the present invention has a half-wavelength structure, and the front metal block is a stepped structure, which reduces the weight and is more convenient to carry; and it satisfies the mechanical properties while improving the acoustic properties.
