Further improvement is: described knife bar and cutter head one-body molded.
Further improvement is: the outer surface of described handle of a knife has anti-skidding lines.
The beneficial effects of the utility model are:
1, in this utility model, the bottom of cutter head has a bifurcation ostium, and the edge of this bifurcation ostium is blade.Therefore, this utility model convenient, fastly can complete vertebral body trailing edge osteotomy, shortens operating time, reduces intraoperative hemorrhage, reduces the risk of spinal cord injury.
2, in this utility model, the first end that bifurcation ostium comprises forward fold and the second end extended straight down, and the length of first end is greater than the length of the second end.Because the second end is vertically arranged, be beneficial in cutter head quick insertion bone, facilitate medical personnel to carry out operation technique, shorten operating time, reduce intraoperative hemorrhage, reduce the risk of spinal cord injury.
3, in this utility model, bifurcation ostium comprises first end and the second end of equal forward fold, and the length of first end is greater than the length of the second end; The bottom of first end and the bottom of the second end, be positioned on same level line.Therefore, medical personnel are in deep operation, and the first end of cutter head and the second end carry out synchronous cutting action by bone, and the length of cutting, the degree of depth are all identical, improve procedure efficiency, reduce the risk of spinal cord injury.
4, in this utility model, the light emitting diode being provided with lamp guide, power supply in knife bar and being connected with power supply, described lamp guide is vertically arranged at below light emitting diode, and the top of lamp guide is relative with the luminous end of light emitting diode, the bottom of lamp guide extends to the bifurcation ostium bottom cutter head, forms focus.Therefore, medical personnel can be thrown light on by focus tool setting head position, facilitate medical personnel to see the inner case of bone clearly, grasp dynamics and the degree of depth of cutting, avoid spinal cord injury.
5, the outer surface of handle of a knife has anti-skidding lines, can prevent doctor from producing when holding handle of a knife and loosen, further increase security performance.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Embodiment of the present utility model, as shown in figures 1 and 3, a kind of spinal osteotomy special vertebral body trailing edge osteotome, comprise handle of a knife 1 and knife bar 2, handle of a knife 1 is installed on the top of knife bar 2, concrete, and the outer surface of handle of a knife 1 has anti-skidding lines, knife bar 2 and cutter head 3 one-body molded and be stainless steel, therefore structure is more firm.The bottom forward fold of knife bar 2 also extends, and form cutter head 3, concrete, the bending angle between cutter head 3 and knife bar 2 is 100 ° ~ 120 °.
In order to make the visual field of medical personnel when cutting openr, be beneficial to operation and carry out, the bottom of cutter head 3 has a bifurcation ostium, and the edge of this bifurcation ostium is blade 312; Concrete, the length of blade 312 is 28mm.Preferably, blade 312 is carved with the scale representing the degree of depth, therefore medical personnel accurately can control the degree of depth of cutting when performing the operation.The top of cutter head 3 is the knife back 311, concrete, and the thickness of the knife back 311 is 3mm; The light emitting diode 5 being provided with lamp guide 6, power supply 4 in knife bar and being connected with power supply 4, described lamp guide 6 is vertically arranged at below light emitting diode 5, and the top of lamp guide 6 is relative with the luminous end of light emitting diode 5, the bottom of lamp guide 6 extends to the bifurcation ostium bottom cutter head, forms focus.Therefore, medical personnel can be thrown light on by focus tool setting head position, facilitate medical personnel to see the inner case of bone clearly, grasp dynamics and the degree of depth of cutting, avoid spinal cord injury.
Shown in Fig. 1 and Fig. 2, in embodiment 1 of the present utility model, the first end 31 that bifurcation ostium comprises forward fold and the second end 32 extended straight down, and the length of first end 31 is greater than the length of the second end 32.Because the second end 32 is vertically arranged, be beneficial in cutter head 3 quick insertion bone, facilitate medical personnel to carry out operation technique, shorten operating time, reduce intraoperative hemorrhage, reduce the risk of spinal cord injury.
Shown in Fig. 3 and Fig. 4, in embodiment 2 of the present utility model, bifurcation ostium comprises first end 31 and the second end 32 of equal forward fold, and the length of first end 31 is greater than the length of the second end 32; The bottom of first end 31 and the bottom of the second end 32, be positioned on same level line.Due to first end 31 and the second end 32 all forward fold, and the bottom of the bottom of first end 31 and the second end 32 is positioned on same level line, therefore, medical personnel are in deep operation, first end 31 and the second end 32 of cutter head 3 carry out synchronous cutting action by bone, and the length of cutting, the degree of depth are all identical, improve procedure efficiency, reduce the risk of spinal cord injury.。
