Description
Technical field
The invention belongs to technical field of medical instruments, specifically a kind of bone surgery separation bone cutter.
Background technology
Autologous bone transplanting is clinical commonly used operative treatment or auxiliary treatment means, is used for repairing wound, infection
And Cranial defect caused by the reason such as bone tumour.Because autologous bone has osteogenic ability (great-hearted osteocyte source), osteoinductive
(aggregation of local mesenchymal cell) and osteoconductive (support that newborn Bone Ingrowth is provided), have identical biology performance and
Good histocompatbility, bone grafting fusion is fast, no transmission risk, therefore increasingly receives and answer for the numerous orthopedists in China
With.The whole world is annual according to statistics 2,200,000 bone collection operations, next in number only to blood transfusion, occupies second.
In clinical orthopaedicses operation, the autologous bone piece majority taken takes Bone mineral change from the bone cipses of operation edge of wound
In the case of row selection crista iliaca, Gerdy tubercles, distal radius, the bone piece such as distal tibial again.In surgical procedure, the fracture taken
Piece or appropriate autologous bone piece are repaired by hand by operative doctor or scrub nurse, remove be adhered to bony surface soft group
Knit, be then trimmed to the moderate bone bar of length and width with rongeur, planted in fracture end and surrounding.Especially in all kinds of spinal operations
In, endplate cartilage and fibrous annulus tissue the fragment adhesion of adhesion are tight to remove difficulty, and judges whether sclerotin simply by virtue of feel
The loss of a part of small skeletal grain is also resulted in, stinging the bone piece removed also needs to be trimmed to acinous implantation intervertenral space, whole operation mistake
Journey is time-consuming longer.Then do not cause bone grafting to fail only if surface soft tissue is removed, or even local infection can be caused.Thus see
Come, the whole process for removing bony surface soft tissue takes time and effort, and has interrupted the continuity of operation, has extended operating time, very
Some negative impacts are brought to meeting patient with operation is possible to, are one of clinical urgent problems to be solved.
The autologous bone tissue taken in operation has a cortex bone and cancellous bone, and cortex bone quality is fine and close and hard, its bone tissue
The Vickers hardness (HV) in three directions is respectively：Section 49.38, side 47.436, surface 43.926；The pressure resistance in three directions
Degree is respectively：Axial 98.07MPa, tangential 136.67MPa, radial direction 163.50MPa.And cancellous bone structure is loose porous, elasticity compared with
Greatly, bone trabecula arrangement is consistent with pressure that bone is born, corresponding tension direction.In clinical operation, skeletal grain is repaiied using rongeur
The whole desirable amount difficulty moderate to length and width is higher, the non-refinement of hand finish, and the skeletal grain of cutting is not often up in one's hands
The requirement of art doctor, and result judges also to be only the sense organ supposition according to operative doctor and micro-judgment, is usually planted in operation
The situation that skeletal grain after entering is repaired repeatedly after taking out, it is unfavorable for the postoperative rehabilitation of patient.
