Abstract
The utility model discloses a bone piece repositor for a tibial plateau collapsed fracture. The one piece repository comprises a repositor body and is characterized in that; the repositor body is cylindrical; the front end of the repositor body is a 80 to 130 degrees bend; an internal thread is arranged in the bend; a round moveable head is arranged on the bend; a convex external thread is arranged at the lower end of the bend; and a round blunt tip is arranged on the tail part of the repositor body. When the bone piece repositor is used, a window is formed in a 2 to 3cm range on the lower edge of an inner side plateau or an outer side plateau on the upper section of a tibia according to the collapsed fracture on the inner side or the outer side of a tibial plateau; after the window is formed, the round moveable head is inserted into the lower part of the bone piece, the direction of the repositor is adjusted to keep the upper surface of the moveable head in the same plane with a joint face of the collapsed bone piece; a knee joint is turned inwards or outwards to tightly joint a plateau joint on the collapsed side; the round blunt tip on the tail part of the repositor body is slowly knocked by a hammer; the repositor body is gradually adjusted while the round blunt tip is knocked to gradually adjust the upper surface of the moveable head of the moveable head to the same plane with a joint clearance; and the round blunt tip is knocked until a resistance force is generated.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of tibial plateau collapsed fracture bone block reset device.
Background technology
At present, well-known, for the tibial plateau collapsed fracture, particularly inclined to one side central type, method commonly used clinically at present is to window at the tibial plateau lower edge, carries out percutaneous reduction by leverage, bone grafting under the bone piece with orthopaedics such as Kirschner wire, osteotome, periosteal elevator or curet apparatus commonly used.But the difficulty or reset undesirablely of often occurring resetting in the clinical manipulation process and lacks accuracy, and the spongy bone bone loss is obvious under the bone piece.Some large hospital begins to use and carries out the bone block reset under the arthroscope assisting navigation, but that the arthroscopic techniques operation requires is high, and basic hospital is difficult to carry out.So far, also there is not the special simple bone block reset apparatus of a cover clinically.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of tibial plateau collapsed fracture bone block reset device simple in structure, easy to use is provided.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of tibial plateau collapsed fracture bone block reset device, it comprises body, it is characterized in that: described body is cylindrical, described body front end is a 80-130 degree elbow, be provided with female thread in the elbow, elbow is provided with circular movable head, and the movable head lower end is provided with the outside nut of protrusion, and described body afterbody is provided with circular blunt nosed.During use according to tibial plateau inboard or outside collapsed fracture, in tibia epimere inboard or outside platform lower edge 2-3cm scope inwardly opened window, after windowing circular movable head is inserted below the bone piece, adjust the body direction, make above the movable head and keep same plane with the bone piece articular surface that subsides earlier, in turn over or the valgus joint, make the side platform joint close apposition of subsiding, slowly knock the circular blunt nosed of body afterbody with hammer, also adjust body when knocking gradually, make to be adjusted to gradually above the body movable head to keep same plane, knocked till certain resistance with the joint space.X line fluoroscopic machine perspective is observed the bone block reset situation of subsiding down, if dissatisfied, can reset once with said method once more.Note in the operating process firmly slowly, soft, progressive, must guard against firmly excessively, reset and be advisable with 1 to 2 time, otherwise can cause the excess compression of spongy bone, cause losing of bone amount.
The beneficial effects of the utility model are: simple in structure, easy to operate, reduced losing of Grafting Cancellous Bone Bolt amount under the bone piece.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Accompanying drawing is a structural representation of the present utility model.
1. bodies among the figure, 2. elbow, 3. female thread, 4. movable head, 5. outside nut is 6. circular blunt nosed.
The specific embodiment
In the drawings, a kind of tibial plateau collapsed fracture bone block reset device, it comprises body 1, it is characterized in that: described body 1 is cylindrical, described body 1 front end is a 80-130 degree elbow 2, is provided with female thread 3 in the elbow 2, and elbow 2 is provided with circular movable head 4, movable head 4 lower ends are provided with the outside nut 5 of protrusion, and described body 1 afterbody is provided with circular blunt nosed 6.During use according to tibial plateau inboard or outside collapsed fracture, in tibia epimere inboard or outside platform lower edge 2-3cm scope inwardly opened window, after windowing circular movable head 4 is inserted bone piece below, adjust body 1 direction, make above the movable head 4 and keep same plane with the bone piece articular surface that subsides earlier, in turn over or the valgus joint, make the side platform joint close apposition of subsiding, slowly knock circular blunt nosed 6 of body 1 afterbody with hammer, also adjust body 1 when knocking gradually, make to be adjusted to gradually with the joint space above body 1 movable head 4 to keep same plane, knocked till certain resistance.X line fluoroscopic machine perspective is observed the bone block reset situation of subsiding down, if dissatisfied, can reset once with said method once more.Note in the operating process firmly slowly, soft, progressive, must guard against firmly excessively, reset and be advisable with 1 to 2 time, otherwise can cause the excess compression of spongy bone, cause losing of bone amount.
