Description
Technical field
The utility model belongs to a kind of medical instruments, and in particular to a kind of posterior cruciate ligament of knee stop protector.
Background technology
In posterior cruciate ligament of knee type TKA (CR type TKA) is retained, posterior cruciate ligament of knee (PCL) Secondary cases
Failure is postoperative prosthese failure, patient to the unsatisfied major reason of knee joint function.Therefore, PCL integrality is protected in art
Success for CR types TKA is most important.
There are some researches show, when the hypsokinesis of Tibial osteotomy face is 7 degree, intersection stop is all located on osteotomy surface after 70%, because
Sclerotin is easily damaged in Tibial osteotomy by goose saw at this PCL shin bone stop.In conventional surgery techniques, the guarantor of PCL stops
Shield is knocked in sclerotin using common osteotome dependent on patient and protected.The defect of this conventional method is：If osteotome is squeezed into
It is too deep, it can cause to connect weak between tibial plateau rear ligament stop and bone bed, easy secondary avulsion fracture；If squeezed into
It is shallow, then it can not stop goose saw, easily cause the bone piece that PCL stops follow shin bone proximal segment deep and be truncated together.
Therefore it provides a kind of posterior cruciate ligament of knee stop protector, to control the placed-depth of protector, it is to avoid stop is protected
Shield device insert it is too deep, to avoid cutting the mistake of stop protector in surgical procedure, so as to improve the percentage of head rice of stop protector,
And stability is inserted in raising simultaneously, the recycling rate of waterused of stop protector is realized, medicine equipment use cost is reduced, just turns into this
Art personnel's urgent problem to be solved.
