As preferably, the cutter head end of described knife bar is provided with top cutter and bottom knife; Described sleeve is provided with a long groove, the side of described knife bar is also installed with a joint pin, this joint pin stretches out from long groove, and the end of joint pin is also provided with slide block.
As preferably, described long groove is also provided with the stopper slot protruded to both sides; This stopper slot is also connected with outward extending L shape groove, and the tail end of described L shape groove is also provided with semicircle draw-in groove.
As preferably, the width of described stopper slot, L shape groove and semicircle draw-in groove is all greater than the diameter of joint pin.
As preferably, the vertical dimension of described semicircle draw-in groove and long groove is greater than 5cm.
As preferably, described stopper slot is provided with three altogether, and adjacent stopper slot spacing is equal, and is all arranged on long groove one side.
As preferably, described top cutter is serrated blade; Bottom knife is blade-like blade.
As preferably, in described housing, be also provided with fluidic device.
Beneficial effect: compared with prior art, the present invention has the following advantages:
(1) cutter head of the present invention is arranged to zigzag upper cutter head and cultrate lower cutter head, and zigzag upper cutter head coordinates the vibration of ultrasonic vibrator to may be used for the cutting of hard bone tissue; And cultrate lower cutter head can cut cartilaginous tissue, or the vibration of ultrasonic vibrator can be coordinated to cut some neutral osseous tissues, different osseous tissues can be cut, diverse in function, easy to operate;
(2) sleeve of the present invention arranges long groove, the joint pin that knife bar is installed stretches out from long groove, therefore knife bar can be driven to move in sleeve by moving slider, the length of knife bar can be regulated like this, and when slide block is moved near some stopper slots, screwed in joint pin in stopper slot by swivel knife carrier, now when knife bar moves, two extension springs of its tail end are strained gradually; And knife bar continues to rotate until screw in the semicircle draw-in groove of L shape groove tail end, because the vertical dimension of semicircle draw-in groove and long groove is greater than 5cm, it rotates great efforts, during rotation, two extension springs of knife bar tail end not only produce axial tightening force, but also create two extension springs winding power along knife bar radial direction each other, therefore tightly can fix in semicircle draw-in groove by the joint pin on knife bar under the effect of the power of both direction, its fastening great efforts, regulative mode is also very convenient;
(3) stopper slot on long groove of the present invention is provided with multiple, and therefore the length adjustment of knife bar is provided with multiple gear, uses also very convenient.
