Abstract
The invention discloses an ultrasonic cutting tool and an application method thereof. The ultrasonic cutting tool comprises a piezoelectric ceramic power supply, a rear base, a transverse piezoelectric ceramic plate, a front base and a cutter. The transverse piezoelectric ceramic plate is located between the rear base and the front base. The cutter is connected with the transverse piezoelectric ceramic plate through the front base. The piezoelectric ceramic power supply is used for generating alternating current power signals with the specific frequency, driving the transverse piezoelectric ceramic plate to generate mechanical vibration, and enabling the whole formed by the ultrasonic cutting tool and a texture to be cut to be in a resonance state. The transverse piezoelectric ceramic plate is used for driving the cutter to generate transverse vibration perpendicular to the axis. The rear base and the front base are used for amplifying the transverse vibration of the transverse piezoelectric ceramic plate. The cutter is used for cutting. The ultrasonic cutting tool is capable of avoiding harmful influence of ultrasonic cavitation effects and the like on the texture.
Description
Technical field
The present invention relates to technical field of medical instruments, relate in particular to a kind of ultrasonic cut instrument and using method thereof.
Background technology
The ultrasonic cut instrument is the piezoelectric effect of utilizing piezoelectric ceramics, ac signal is changed into vibrational energy or the cavitation effect of machinery, thereby reaches the effect of pulverizing tissue.
At present, vibration commonly used is the longitudinal vibration mode of piezoelectric ceramics, and namely direction of vibration is along the axis direction of cutting device, and supersonic vibration direction in other words is parallel with the normal direction of tissue regions to be cut.The major defect of the method is that hyperacoustic direction of propagation is consistent with cut direction, and ultrasonic energy is propagated along direction of vibration, easily damages interior tissue.
Summary of the invention
The object of the invention is to propose a kind of ultrasonic cut instrument and using method thereof, can avoid the harmful effects to organizing such as ultrasonic cavitation effect.
For reaching this purpose, the present invention by the following technical solutions:
A kind of ultrasonic cut instrument, comprise piezoelectric ceramics power supply, rear pedestal, horizontal piezoelectric ceramic piece, front pedestal and cutter, described horizontal piezoelectric ceramic piece is between described rear pedestal and described front pedestal, described cutter is connected to described horizontal piezoelectric ceramic piece by described front pedestal, wherein, described piezoelectric ceramics power supply is for generation of characteristic frequency AC power signal, drive horizontal piezoelectric ceramic piece and produce mechanical vibration, and the integral body that described ultrasonic cut instrument and tissue to be cut are consisted of is in resonant condition;
Described horizontal piezoelectric ceramic piece is used for the oscillation crosswise of cutter generation perpendicular to axis;
Described rear pedestal and described front pedestal are for the oscillation crosswise of amplifying described horizontal piezoelectric ceramic piece;
Described cutter is used for cutting.
Described cutter adopts different length, for generation of various amplitude.
A kind of using method of ultrasonic cut instrument comprises the following steps:
Piezoelectric ceramics power supply produces characteristic frequency AC power signal;
Laterally piezoelectric ceramic piece produces oscillation crosswise;
Front pedestal and rear pedestal amplify the oscillation crosswise of described horizontal piezoelectric ceramic piece;
Front pedestal band cutter produces the oscillation crosswise perpendicular to axis.
Further comprising the steps of:
Adjust the length of cutter, to produce various amplitude.
Adopted technical scheme of the present invention, surperficial parallel due to the direction of vibration of cutting tool and tissue to be excised is so can avoid ultrasonic cavitation effect etc. to the harmful effect of tissue.
Description of drawings
Fig. 1 is the structural representation of ultrasonic cut instrument in the prior art scheme.
The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
Fig. 1 is the structural representation of ultrasonic cut instrument in the prior art scheme.As shown in Figure 1, this ultrasonic cut instrument comprises piezoelectric ceramics power supply 1, rear pedestal 2, horizontal piezoelectric ceramic piece 3, front pedestal 4 and cutter 5, and laterally piezoelectric ceramic piece is between rear pedestal and front pedestal, and cutter is connected to horizontal piezoelectric ceramic piece by front pedestal.
When using the ultrasonic cut instrument, at first switch on power, piezoelectric ceramics power supply produces characteristic frequency AC power signal, drive horizontal piezoelectric ceramic piece and produce horizontal mechanical vibration, and the integral body that ultrasonic cut instrument and tissue to be cut are consisted of is in resonant condition, front pedestal and rear pedestal amplify the oscillation crosswise of horizontal piezoelectric ceramic piece, and by the oscillation crosswise of front pedestal band cutter generation perpendicular to axis.
Like this, surperficial parallel due to the direction of vibration of cutting tool and tissue to be excised is so can avoid ultrasonic cavitation effect etc. to the harmful effect of tissue.
In order to produce as required different vibration amplitudes, can realize by the length of adjusting cutter.
The above; only for the better specific embodiment of the present invention, but protection scope of the present invention is not limited to this, anyly is familiar with the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement are within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
