Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of ultrasonic cut instrument and using method thereof.
Background technology
Ultrasonic cut instrument is the piezoelectric effect utilizing piezoelectric ceramics, ac signal is changed into vibrational energy or the cavitation effect of machinery, thus reaches to pulverize the effect of tissue.
At present, the conventional longitudinal vibration mode that vibration is piezoelectric ceramics, i.e. direction of vibration is along the axis direction of cutting device, and supersonic vibration direction is parallel with the normal direction of tissue regions to be cut in other words.The major defect of the method is that the direction of propagation of ultrasound wave is consistent with cut direction, makes ultrasonic energy propagate along direction of vibration, easy damaging internal tissues.
Summary of the invention
It is an object of the invention to propose a kind of ultrasonic cut instrument and using method thereof, it is possible to avoid the harmful effect to tissue such as ultrasound cavitation effect.
For reaching this purpose, the present invention by the following technical solutions:
A kind of ultrasonic cut instrument, including 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 used for producing characteristic frequency AC power signal, drive horizontal piezoelectric ceramic piece to produce mechanical vibration, and make that described ultrasonic cut instrument and tissue to be cut constituted generally in resonant condition；
Described horizontal piezoelectric ceramic piece produces the oscillation crosswise being perpendicular to axis for band cutter；
Described rear pedestal and described front pedestal are for amplifying the oscillation crosswise of described horizontal piezoelectric ceramic piece；
Described cutter is used for cutting.
Described cutter uses different length, is used for producing various amplitude.
The using method of a kind 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 being perpendicular to axis.
Further comprising the steps of:
Adjust the length of cutter, to produce various amplitude.
Have employed technical scheme, owing to the direction of vibration of cutting tool is parallel with the surface treating resection organization, it is possible to avoid the harmful effect to tissue such as ultrasound cavitation effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of ultrasonic cut instrument in prior art.
Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
Fig. 1 is the structural representation of ultrasonic cut instrument in prior art.As it is shown in figure 1, this ultrasonic cut instrument includes piezoelectric ceramics power supply 1, rear pedestal 2, horizontal piezoelectric ceramic piece 3, front pedestal 4 and cutter 5, horizontal piezoelectric ceramic piece is between rear pedestal and front pedestal, and cutter is connected to horizontal piezoelectric ceramic piece by front pedestal.
When using ultrasonic cut instrument, first switch on power, piezoelectric ceramics power supply produces characteristic frequency AC power signal, horizontal piezoelectric ceramic piece is driven to produce horizontal mechanical vibration, and make that ultrasonic cut instrument and tissue to be cut constituted generally in resonant condition, the oscillation crosswise of horizontal piezoelectric ceramic piece is amplified by front pedestal and rear pedestal, and is produced the oscillation crosswise being perpendicular to axis by front pedestal band cutter.
So, owing to the direction of vibration of cutting tool is parallel with the surface treating resection organization, it is possible to avoid the harmful effect to tissue such as ultrasound cavitation effect.
In order to produce different vibration amplitudes as required, can be realized by the length adjusting cutter.
The above; being only the present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, and any is familiar with the people of this technology in the technical scope that disclosed herein; the change that can readily occur in or replacement, all should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with scope of the claims.
