Background technology
Due to a lack of blood supply, innervation and lymphatic return, chondrocyte only accounts for articular cartilage to the articular cartilage of human body
The 1-5% of volume, the reason such as chondrocyte division growth inferior capabilities, cause the self-repairing capability of cartilage injury poor.Close
After section cartilage injury, if can not timely and effectively treat, osteoarthritis may be further developed into, to patient and society's band
Carry out white elephant.
Articular cartilage damage still lacks more effective Therapeutic Method at present, and existing therapy includes expectant treatment and operation is controlled
Treat, operative treatment includes microfrature and skin grafing and mending, because simple to operate, current clinical practice is wide for microfrature, but
Its long-term effect is unsatisfactory and is not suitable for large area cartilage injury.Skin grafing and mending be cartilage injury reparation bring new
Wish, current graft includes many kinds, can be used for clinical inclusion chondrocyte induction regeneration membrane, decalcification bone supporting stand, fibrin
Glue support etc..Carry out skin grafing and mending art under arthroscope and organizational project prothesiss have the advantages that wound is little, it is fast to recover.Graft
Fixed form have multiple, wherein, position Da Gu road, nail afterwards or the fixation of bone bridge be one of mode the most firm.
But because joint inner structure is more complicated, during Da Gu road, positioning has a larger difficulty, and clinically lack special soft at present
Bone Defect Repari bone road alignment system, has a strong impact on the process of operation technique, extends operating time, increased the operation risk of patient.
Content of the invention
For the problems referred to above, it is an object of the invention to provide a kind of prosthetic locating guider of articular cartilage damage.
For achieving the above object, the present invention employs the following technical solutions: a kind of prosthetic positioning of articular cartilage damage is led
