Abstract
The utility model relates to a thoracic and lumbar vertebrae outer fixing device, which is composed of four screw thread nails which are provided with sleeve barrels and screw nuts and are used for penetrating a needle through a skin, four connectors and two connecting rods which are respectively provided with two connecting sheets, wherein the screw thread nail is arranged in a through hole of the screw thread nail on every connector and is fixed on every connector through a screw. Two ends of the connecting rod with the connecting sheet are respectively provided with the connectors, and the connecting rod is inserted into the connecting rod hole on every connector and is fixed on every connector through the screws. The screw is arranged on the connecting sheet, and an open groove is arranged on the other connecting sheet. Through the screw and a nut, two connecting sheets are connected together, and consequently, two connecting rods with the connectors are connected together.
Description
Technical field
This utility model relates to a kind of orthopedic medical device, particularly a kind of spinal trauma fixation of fractures device that is applied to.
Background technology
The therapeutic scheme of domestic and international spinal trauma compression fracture at present and paresis paralysis, the general open reduction of operation that adopts adds the steel plate internal fixation operation, after union of fracture, also need the taking-up operation of inside-fixture for the second time, this method exists the otch big muscle to peel off defective widely, the patient suffering is big, and the hospital stays is long, the corresponding medical expense height that occurs, overhaul if any loosening must surgical incision the resetting once more of internal fixation simultaneously, the time that the patient lies in bed is long.Be unfavorable for fracture surgery early function reconditioning in addition behind the internal fixation.Chinese patent 01245455.9 discloses a kind of " external spinal fixator and reductor for treating of treatment lumbar vertebra compression fracture ", this positor adopts the in-vitro percutaneous outside reduction of threading a needle to regulate fixing, though solved the problem of above-mentioned existence, but this positor does not lift reset function, and complex structure, volume is bigger, operation inconvenience.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, provides a kind of open reduction internal fixation treatment with the spinal trauma fracture to change the in-vitro percutaneous outside reduction of threading a needle into and regulates the lumbar-thoracic spine external fixator that fixation for treatment is used.The lumbar-thoracic spine 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: the lumbar-thoracic spine external fixator 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.Adapter is provided with a bar shaped blind hole, the bottom of bar shaped blind hole is provided with a drive screw through hole, also be provided with the screwed hole of retaining thread nail usefulness and screwed hole and the tie rod holes that stationary links is used on the adapter, the screwed hole of retaining thread nail usefulness communicates with the bar shaped blind hole, and the screwed hole that stationary links is used communicates with tie rod holes.All be provided with a drive screw in the drive screw through hole on each adapter, and be fixed on the adapter by screw.The connecting rod two ends that have brace respectively are provided with an adapter, and connecting rod inserts in the tie rod holes on the adapter, and will be fixed on the connecting rod on the adapter by screw.A slice brace is provided with screw, and another sheet brace is provided with open slot, by screw and nut two braces is linked together, thereby two connecting rods that have adapter are linked together.
The lumbar-thoracic spine external fixator that this utility model provides adopts rustless steel or titanium metal material to make.
The lumbar-thoracic spine external fixator that adopts this utility model to provide in the treatment of spinal trauma compression fracture and paresis paralysis relatively has following advantage 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 reduction of spinal fracture and fix under percutaneous pinning.
2. simple to operate, reduce the auxiliary treatment of some open reduction internal fixation, can reduce the patient treatment expense greatly.
3. after the reduction external fixation is treated, but early ambulation carries out functional exercise to reduce the generation of complication.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
