Description
Technical field
This utility model relates to a kind of orthopedic medical device, particularly a kind of reduction external fixer that is applied to spinal trauma fracture or deformity of spine.
Background technology
Present spinal trauma fracture back or deformity of spine reduction fixation for treatment generally adopt the open reduction and internal fixation treatment of performing the operation both at home and abroad.The open reduction and internal fixation treatment of operation also needs the taking-up operation of inside-fixture for the second time after union of fracture, because inside-fixture is overlong time in vivo, cause easily the internal fixation broken nail and fixedly vertebral body close on the intervertebral disc degeneration complication, the corresponding medical expense height that occurs, simultaneously also bring loaded down with trivial details and complicated in the treatment to the doctor, the time of patient's bed is long, is unfavorable for the fracture surgery functional rehabilitation exercise, and the misery of bringing to the patient is big.Chinese patent 200520051825.2 discloses a kind of " lumbar-thoracic spine external fixator ", and it has the percutaneous pinning drive screw of sleeve and nut, four adapters and two connecting rods that respectively have a bump contacted chip respectively by four and forms (seeing accompanying drawing 13,14).It is fixing that this positor adopts the in-vitro percutaneous outside reduction of threading a needle to regulate, though solved the problem of above-mentioned existence, only is used for the treatment of compressed fracture of thoracic vertebra and lumber vertebra reduction external fixation, can not be used for the deformity of spine treatment, and the scope of application is little.In addition, this positor brace structure is thiner, and stressed back easy deformation is difficult to keep three-dimensional fixation.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and a kind of outer solid device that just can finish spinal fracture and deformity of spine reduction under percutaneous pinning is provided.The multi-segmental spinal column reduction external fixator that this utility model provides also has the reset function of lifting, and simple in structure, volume is little, and is easy to operate.
The technical solution of the utility model is: multi-segmental spinal column reduction external fixator, it comprises four and has the percutaneous pinning drive screw of sleeve and nut, four adapters and two connecting rods, the percutaneous pinning drive screw is fixed on the adapter by screw, and adapter is fixed on the connecting rod by screw.Two connecting rods are fixed together by connecting device.Connecting device is made up of insert and contiguous block, one end of insert is provided with a hook groove, the other end is that the cross section is quadrate inserted block, the top of inserted block is provided with a position-limitting pin, on insert, also be provided with a sunk screw hole that is threaded the hole, screwed hole communicates with the hook groove, and insert is buckled on the connecting rod, is fixed on the connecting rod by sunk screw.One end of contiguous block is provided with a hook groove, which is provided with a sunk screw hole that is threaded the hole, screwed hole communicates with the hook groove, contiguous block is buckled on the connecting rod, be fixed on the connecting rod by sunk screw, the other end of contiguous block is provided with a square hole, and square hole is provided with a spacing cotter way and a screwed hole, and screwed hole and square hole communicate.Inserted block on the insert inserts in the square hole of contiguous block, and fixes by screw.On connecting rod, also be provided with one group of adapter that is used for deformity of spine treatment at least, all be provided with strip through-hole, tie rod holes and connecting rod screwed hole on the adapter that every group is used for the deformity of spine treatment.Every group of adapter that is used for the deformity of spine treatment is two, is through on the connecting rod respectively, and is screwed.Each is used for all being provided with a percutaneous pinning drive screw that has sleeve and nut in the strip through-hole on the adapter of deformity of spine treatment.Can establish screwed hole and the screw that is used for fixing the percutaneous pinning drive screw on the adapter that every group is used for deformity of spine treatment, also can not establish.
The multi-segmental spinal column reduction external fixator that this utility model provides adopts rustless steel or titanium metal material to make.
The multi-segmental spinal column reduction external fixator that this utility model provides can not only be regulated the external fixation treatment to the spinal fracture reduction, and can also regulate the external fixation treatment to the deformity of spine reduction.Relatively following advantage is arranged with present all general inner fixers both at home and abroad:
1. the patient suffering is little, does not need surgical incision skin, just can finish the fixing and deformity of spine reconstructive therapy of reduction of spinal fracture under percutaneous pinning.
2. feasible multi-segmental spinal column external fixation, the scope of application is extensive.
3. simple to operate, reduce the auxiliary treatment of some open reduction internal fixation, can reduce the patient treatment expense greatly.
4. after the reduction external fixation is treated, but early ambulation carries out functional exercise to reduce the generation of complication.
5. adopt the rigidity connecting device between two connecting rods, can keep three-dimensional fixation.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
