Description

带平衡特征的超声刀刀头装置 Balanced ultrasonic blade head assembly with the features

技术领域 FIELD

本实用新型属于超声医疗器械领域,涉及一种超声外科手术器械,尤其是带平衡特征的超声刀刀头装置。 The present invention belongs to the field of ultrasonic medical equipment, it relates to an ultrasonic surgical instrument, in particular ultrasonic blade head assembly with the balance characteristics.

背景技术 Background technique

目前,超声的应用日益广泛,不少行业均有涉及,像超声焊接、超声乳化、 超声无损探伤、超声影像及超声切割等。 Currently, the increasingly widespread use of ultrasound, many industries are involved, such as ultrasonic welding, ultrasonic emulsification, ultrasonic nondestructive testing, ultrasonic imaging and ultrasonic cutting. 在医学上,超声也有相当的应用,比如超声刀就是其中一种,它利用刀头的高频率振动切割组织,并具有较好的止血功能。 In medicine, ultrasound has considerable applications, such as ultrasonic blade is one of them, which uses high-frequency vibration of the tip to cut tissue, and has good hemostatic function.

超声刀在外科手术中的应用日益普及,系统携带的激励源或发生器产生高频交流电信号,超声换能器利用压电材料或磁致压縮材料将其转换成纵向为主的机械振动,并通过超声放大器将振动放大后由超声波导管传递到末端作用器及其功能部件(刀头),对组织进行切割。 Ultrasonic surgical blade in the increasing popularity of portable system excitation source or a high frequency alternating current signal generator, an ultrasonic transducer using a piezoelectric material or a magneto-compressed material to convert it into longitudinal mechanical vibration based and after passing by the ultrasonic vibration amplified by the amplifier to the action of the ultrasound catheter tip and the functional component (head), the tissue cut. 在设计上,需保证这些振动部件固有频率相近,工作时才能同频振动,即共振,以获得效率最高。 In the design, the need to ensure the natural frequency of the vibration member are similar, in order to work with the frequency of vibration, i.e. resonance, to obtain maximum efficiency. 在这种纵向超声波振动下,超声刀的整体结构需对称,工作时刀头才能保持平衡,利于切割和止血的功能实现。 In this longitudinal ultrasonic vibration, for an overall configuration of the ultrasonic blade symmetry, the bit in order to maintain balance during operation, facilitates cutting and hemostasis function realization. 但是,实际应用中的超声刀刀头,出于手术方面的考虑,往往做成弯曲等各种不对称结构,使得刀头在使用中失衡,影响其功能和使用寿命。 However, the ultrasonic blade tip practical application, the operation aspect of the considerations, often made asymmetrical bending and other structures, so that, in use, the tip imbalance, affect its function and service life.

图1所示为现有超声刀产品的刀杆部分,包括超声波导管11和末端作用器 Figure shank portion is conventional ultrasonic blade products, including ultrasound catheter 11 and the end effector 1

12 (刀头)两部分,13为该弯曲刀头的重心位置,由于刀头的不对称结构,例如Y方向弯曲,刀头重心13将会偏离纵向轴心,从而导致末端通常会有X、 Y 至少两个方向的振动偏移,这种偏移量和刀头重心偏移纵轴成正比。 (Bit) in two parts 12, 13 for bending the tip of the gravity center position, due to the asymmetric structure of the head, such as bending in the Y direction, the center of gravity head will be offset from the longitudinal axis 13, resulting in the end there is usually X, Y vibrational displacement of at least two directions, which shift the focus shift amount and the vertical axis is proportional to the tip. 刀头不平衡所导致的非轴向振动偏移量,即超声波振动,不仅降低了超声刀的效率,同时还会反射回超声刀刀杆,容易导致其受损,刀头也容易因为频率失衡和非轴向偏移量过大而碎裂,从而可能会影响超声刀的寿命和使用安全性。 Non-axial vibration caused by imbalance of the bit offset, i.e. ultrasonic vibration, not only reduces the efficiency of the ultrasonic blade, while also reflected back to the ultrasonic blade arbor easily cause damage, because the frequency of the head can be easily imbalances and the non-axial offset too fragmented, which may affect the life of the ultrasonic blade and safety in use.

一般来说,较理想的情况是非轴向的偏移量不能大于15% (即非轴向的振幅和轴向振幅的比值百分数),最好是在5%以下。 Generally, non-ideal situation can not be axially offset greater than 15% (i.e. the ratio of the percentage of non-axial and axial amplitude of the amplitude), preferably 5% or less. 很显然,现有的超声刀刀头因采用弯曲等不对称结构,非轴向的偏移量一般在15%甚至更高,刀头在使用中很容易失衡和损坏,曾经有通过改变刀头形状或采用不对称结构时减重(减小截面) 的方法来达到平衡的目的,但是减重会削弱刀头的强度,改变刀头形状又会影响其使用的功能,均不是有效的方法。 Obviously, the conventional ultrasonic blade tip due to bending using an asymmetric structure, non-axial offset is generally 15% or higher, the bit in use, and easily damaged imbalance, by changing the bit had loss (reduced cross-sectional) shape, or an asymmetric structure using a method to achieve the purpose of the balance, but the weight loss will weaken the tip, the tip changing its shape will affect the function of use, are not effective.
