Through the scheme, not only the cutting length of the bone can be adjusted, but also the cutting angle (including the varus and valgus angle and the buckling angle) of the bone can be adjusted, so that bones with different shapes and lengths can be cut according to the bone condition of a patient, doctors can be helped to cut bones from all directions and all sizes, actual requirements are met to the maximum extent, normal states of the patient are restored, and good news is brought to the patient. Therefore, the application range of the omnibearing fine-tuning osteotomy device can be enlarged, so that the omnibearing fine-tuning osteotomy device can be better suitable for different osteotomy requirements.
In the invention, when the movable end of the buckling adjusting mechanism 3 drives the osteotomy mechanism 5 to overturn around the X axis, the adjusting angle is the buckling angle, and the overturning range is +/-8 degrees, namely, the rotatable range of the osteotomy mechanism 5 around the X axis is 16 degrees; when the adjusting end of the inclination angle adjusting mechanism 4 drives the osteotomy mechanism 5 to turn around the Y axis, the adjusting angle is the inside-out turning angle. And the turnover range is ±8°, that is, the range in which the osteotomy mechanism 5 can be rotated about the Y axis is 16 °. The bone quantity adjusting mechanism 2 is mainly used for adjusting the bone quantity, and the adjusting range is +/-8 mm, namely, the adjusting range of the bone quantity is 16mm.
In one embodiment of the present invention, the bone quantity adjusting mechanism 2 includes a first knob 21, a first rack 22, and a first gear 23 engaged with the first rack 22; the length direction of the first rack 22 is parallel to the Z direction; the first rotary column 21 is rotatably connected to the base 11, and the first gear 23 is fixedly connected to the first rotary column 21 by a key connection manner and is engaged with the first rack 22, so as to drive the first rack 22 to move along the Y direction when the first rotary column 21 is screwed.
Specifically, when the first rotary column 21 is screwed in the first direction, the first gear 23 may be driven to rotate, and at this time, the first gear 23 may transmit a force to the first rack 22, so that the first rack moves in the vertical direction, and the position between the base 11 and the fixing seat 7 is adjusted. When the first rotary column 21 is screwed in the second direction, the first gear 23 can be driven to rotate, and at this time, the first gear 23 can transmit force to the first rack 22, so that the first rack 22 moves in the opposite direction in the vertical direction. Thus, the adjustment of the bone cutting amount is realized.
In one embodiment of the present invention, referring to fig. 1 and 2, the end of the first screw 21 is provided with a first screw cap 24, and at least two arc-shaped grooves 25 are provided on the first screw cap 24, so that the finger web can be tightly attached to the grooves 25, thereby holding the first screw cap 24 to effectively rotate the first screw 21, and thus, adjust the position of the first rack 22.
In the present invention, the first screw cap 24 is provided with 4 arc-shaped grooves 25, and the grooves 25 have curved surfaces, thereby facilitating fitting of the finger abdomen.

The mounting seat 26 is designed to provide a support point for the first screw cap 24 so that the first screw 21 rotates smoothly. In addition, direct abrasion to the outer surface of the fixed seat 7 can be avoided, and further the rotating stability is improved.
It will be appreciated that in the present invention, the first rotary post 21 may be connected to the fixing base 7 in a threaded connection manner, so that the first rotary post may be locked to the fixing base 7 while rotating, preventing the first rotary post from retreating, and thus enabling the first gear 23 to be stably engaged with the first rack 22 for transmission.
In one embodiment of the present invention, the base 11 is provided with the stop slot 12, and the first rack 22 is provided with the stop table 27 corresponding to the stop slot 12, so that when the stop table 27 is clamped in the stop slot 12, the position of the first rack 22 can be limited, thereby preventing the movement range of the first rack 22 from exceeding the limit and affecting the normal use of the osteotome.
In one embodiment of the present invention, the buckling adjustment mechanism 3 includes a second rotation post 31, a second rack 32, and a second gear 33 that mates with the second rack 32; the length direction of the second rack 32 is parallel to the Z direction, and the second rack 32 is connected to the osteotomy mechanism 5.
The second rotary column 31 is rotatably connected to the fixing seat 7, and the second gear 33 is fixedly connected to the second rotary column 31 in a key connection manner and is meshed with the second rack 32, so that when the second rotary column 31 is screwed, the second rack 32 can be driven to move along the Y direction, and the osteotomy mechanism 5 is driven to overturn around the X axis.
Specifically, when the second rotary column 31 is screwed along the first direction, the second gear 33 may be driven to rotate, and at this time, the second gear 33 may transmit a force to the second rack 32, so as to move in the vertical direction, and further drive the osteotomy mechanism 5 to turn around the X-axis, that is, make the osteotomy mechanism 5 deflect. When the second rotary column 31 is screwed in the second direction, the second gear 33 can be driven to rotate, and at this time, the second gear 33 can transmit force to the second rack 32, so that the second rack 32 moves in the opposite direction in the vertical direction, and further drives the osteotomy mechanism 5 to swing in the opposite direction. Thereby, the adjustment of the magnitude of the buckling angle is achieved.
The first direction means a clockwise direction or a counterclockwise direction, and the second direction means a direction opposite to the first direction, and is a counterclockwise direction or a clockwise direction, respectively.
And when the second knob 31 is screwed, the second rack gear 32 is moved upward or downward depending on the position of the first rack gear 22 with respect to the second gear 33. For example, when the second rack 32 is positioned on the right side of the second gear 33 (as understood against the direction of the drawing seen with naked eyes), the second knob 31 is screwed clockwise, so that the second rack 32 can be moved downward; and the second rack gear 32 can be moved upward by twisting the second knob 31 counterclockwise.
