Referring to Fig.1 shown in -8, a kind of minimally invasive restorer of tibial plateau collapsed fracture block includes top stick ontology 1, pushes up stick sheet
Body 1 is arranged at tubular structure, and top stick ontology 1 includes the slip hole 11 of coaxial arrangement, and the cross section of slip hole 11 is at just polygon
Shape structure setting, sliding is connected with cross section into the drive rod 12 of regular polygon structure setting in slip hole 11, drive rod 12
Outer circumferential wall is bonded with the circumferential inner sidewall of slip hole 11, is hinged with top plate 13, top plate on the lateral wall of 12 end of drive rod
One end of 13 length directions and the end edge of drive rod 12 are hinged, the other end of top plate 13 and the one of 14 length direction of support plate
End is hinged, and the other end of 14 length direction of support plate is hinged for protruding into the end in pulp cavity with top stick ontology 1, and top plate 13 is arranged
Have multiple, and the quantity of top plate 13 and the lateral surface quantity of drive rod 12 are consistent, and each top plate 13 is around drive rod
On 12 outer circumferential wall, top stick ontology 1 is provided with the driving being spirally connected with drive rod 12 far from the end for protruding into one end in pulp cavity
Nut 15, driving nut 15 is axial to be limited and is connected to circumferentially rotating on the stick ontology 1 of top, drives nut 15 in rotation process
In be able to drive drive rod 12 and slid along its length in slip hole 11.
In tibial plateau collapsed fracture surgical procedure, the first tibial bone cadre position " windowing " under tibial plateau of patient
(removing partial cortical with osteotome) then will push up stick ontology 1 and be protruded into from osseous tunnel until positioned at the lower section of tibial plateau, then be passed through
Rotate driving nut 15 makes that nut 15 is driven to be able to drive the sliding outward along its length in slip hole 11 of drive rod 12,
So as to make the end of drive rod 12 close to the end of top stick ontology 1, realize that top plate 13 is axial around the rotation with drive rod 12
Outer rotation, and support plate 14 is turned out around the rotation axis with top stick ontology 1, so as to realize the end for expanding restorer
Area can jack up the bone block for collapsing position greater than osseous tunnel diameter, while guaranteeing to jack up effect, can also facilitate patient
