Bone amount, after the alveolar bone situation that tooth patient is planted in assessment, if the alveolar bone for planting tooth patient goes out because periodontosis or agomphosis are too long
When existing serious defect or atrophy, must just carry out taking bone and Psoralen, to avoid bone vallum part it is bad and cause to plant after tooth pain or
Situations such as implant loosens.
For a long time, bone renovating material mainly includes autologous bone, with (different) kind allograph bone, artificial synthesis bone etc..Allograph bone
It is extremely difficult, expensive in terms of being implanted in material screening, storing, it is also easy to generate immunological rejection, virus infection etc., failure rate
It is higher.Meanwhile allograph bone is substituted slowly, newborn bone volume is less than normal.Artificial synthesized bone renovating material includes natural polymer
Sub- material, artificial synthesized high molecular material, inorganic material and nano material.There are no one kind perfectly to substitute so far
The material of people's bone.Autologous bone has good biocompatibility, good skeletonization effect, therefore is widely used.
Autologous bone transplanting source mainly includes that plantation nest takes bone and dystopy to take bone in situ, and bone is taken to prepare in plantation nest in situ
Just as washing away for physiological saline causes bone bits loss more in journey, and bone bits is also made to lose activity.Have at present and directly exists
It takes and takes bone drill bit for what bone milled skeletonization bits when bone, or directly take out band saw dentation bone.In repairing bone defect,
Sometimes be also required to complete long bone, at this moment just need it is dedicated take long bone take bone drill bit.
Utility model content
Deficiency existing for bone drill bit is taken for current tooth-implanting operation, it is skilful that the utility model is intended to provide a kind of structure
Wonderful, easy to operate, have more chip-removal hole takes bone drill bit.
For realization the purpose of this utility model, following technical scheme is taken to be achieved:
One kind taking bone drill bit, including shank, column bone storage unit, drilling portion；One end of the shank is equipped with card slot, institute
Stating card slot can be connected and fixed with the driving device for taking bone drill bit to be adapted to, and the other end of the shank is connected equipped with shank
Mouthful；One end of the column bone storage unit is equipped with port, and the column bone storage unit connects by the way that port and shank connector are fixed
It connects, the column storage unit is hollow structure and is provided with chip-removal hole on the column storage unit, and the column bone stores
Portion's other end is equipped with opening；The one end in the drilling portion is equipped with drilling portion port, and the drilling portion passes through drilling portion port and institute
It states opening to be connected and fixed, the other end in the drilling portion is equipped with blade, and the blade is around the axis annular point in the drilling portion
Cloth.
Further, the shank length is 10~15mm.
Further, the column bone storage unit length is 15~20mm.
Further, the column bone storage unit is provided with graduation mark.
Further, the chip-removal hole is round rectangle structure, axis annular of the chip-removal hole around column bone storage unit
Distribution.
Further, it is one group that the chip-removal hole, which shares 6 and 3, is divided into two groups, each group around column bone storage unit
Axis annular spread.
Further, the drilling portion is equipped with 10 blades.
Further, the blade is v-shaped structure, and the tilt angle in blade cutting face is 15 °~20 °.
Bone drill bit clever structure is taken the utility model has the following beneficial effects: described in the utility model, it is easy to operate, if
There is chip-removal hole to be conducive to the discharge of bone bits.The utility model be conducive to it is clinical combine for bone area anatomical structure, it is safer accurately
Obtain complete column bone.
