Technical Field
The invention relates to the technical field of bone curet medical instruments, in particular to a reverse curet under an endoscope.
Background
With the concept of minimally invasive spinal surgery being increasingly sophisticated, more and more spinal surgeons are currently using minimally invasive surgery as the preferred treatment strategy. The end plates are generally required to be treated by using a bone curette in minimally invasive spinal fusion surgery. When the traditional bone curette is used, the spoon body needs to be stretched beyond tissues to be removed, and redundant tissues are removed through a digging action. Because the minimally invasive surgery has limited visual field, the risk of damaging surrounding tissues exists when an operator uses the bone curette by hand feeling, and the force application habit is not met. Meanwhile, due to the fact that the operation space is limited, the range and the angle which can be removed by a traditional curet are small, and the problems that bone grafting area is relatively reduced due to insufficient end plate treatment and fusion conditions are not ideal enough exist.
