背景技术Background technique
超声刀是利用超声原理能像真刀一样切割人体内部组织的超声波。超声刀主要由主机、驱动柄及连线、刀头及脚踏开关等组成；其工作原理是使用脚踏或手持刀头激活工作，此时主机输出振动系统谐振频率下的电能到驱动柄，由驱动柄将电能转变为机械能并输出到刀头，刀头对此振动进一步放大进行机械振动，使组织细胞内水汽化、蛋白氢键断裂、细胞崩解、组织被切开或凝血，从而达到切割组织和止血的目的。The ultrasonic knife is an ultrasonic wave that can cut the internal tissues of the human body like a real knife by using the principle of ultrasound. The ultrasonic knife is mainly composed of the host, the drive handle and connection, the knife head and the foot switch; its working principle is to use the pedal or the hand-held knife head to activate the work. At this time, the host outputs the electric energy at the resonant frequency of the vibration system to the drive handle. , the drive handle converts electrical energy into mechanical energy and outputs it to the cutter head. The cutter head further amplifies this vibration to perform mechanical vibration, so that the water in the tissue cells is vaporized, the hydrogen bond of the protein is broken, the cells are disintegrated, the tissue is cut or coagulated, thus To achieve the purpose of cutting tissue and hemostasis.
在超声刀的应用中，依赖于刀头的高频率往复运动来产生止血和切割的效果，且对钳口内组织施加的压力是影响其切割速度和止血效果的重要因素，而构成钳口的其中一侧为塑料材料，如果组织切割完成后仍然持续进行切割则会对该塑料垫片进行磨损，磨损至一定程度后，将逐渐的改变钳口间隙，直至垫片被耗尽而使器械无法继续使用。现有的超声刀，医生在使用时必须一直集中精力观察刀头的切割情况，使得医生不能分散注意力，劳动强度大；而且通过肉眼的观察，不能准确的判断组织是否已经切割完，完全依靠经验判断，容易出现长时间空载的情况，导致刀头磨损严重，降低使用寿命。In the application of the ultrasonic scalpel, the effect of hemostasis and cutting depends on the high-frequency reciprocating movement of the cutter head, and the pressure exerted on the tissue in the jaw is an important factor affecting its cutting speed and hemostasis effect, and the jaws constitute one of them. One side is made of plastic material. If the tissue is cut and continues to be cut, the plastic spacer will be worn. After the wear reaches a certain level, the gap between the jaws will be gradually changed until the spacer is exhausted and the instrument cannot continue. use. With the existing ultrasonic scalpel, the doctor must always concentrate on observing the cutting situation of the cutter head when using it, so that the doctor cannot be distracted, and the labor intensity is high; and through the observation with the naked eye, it is impossible to accurately judge whether the tissue has been cut. Judging by experience, it is prone to long-term no-load situations, which will lead to serious wear of the cutter head and reduce the service life.
