Abstract
An orthopedic external fixation support for continuous perfusion and dosing in the utility model belongs to the field of medical equipment and comprises a cross rod, fixation nails, cavity fastening nails and fixation clamps, wherein two vertical cavity fixation nails are installed in an interval manner by the fixation clamp and a vertical fixation nail is respectively connected to the outside of those two nails by two fixation clamps; external threads are disposed one end of each of the fixation nails and cavity fixation nails and side holes are opened on the pipe wall of the cavity fixation nails; and the other ends of the two cavity fixation nails are respectively communicated with an infusion tube and a drainage tube. The fixation support not only solves problems in transformation and blocking in a washing tube cavity, realizes lavage for continuous days and always maintains the lavage smooth, but also controls inflammations through dosing in parts through pipes or prompts fracture healing. In addition, strength of the external fixation support is increased so that osteomyelitis and bone nonunion can be effectively prevented and treated.
Description
One, technical field: but continous pouring administration Orthopaedic external fixator of the present utility model belongs to medical instruments field, relates in particular to a kind of orthopaedics and orthopedic instruments.
Two, background technology: Orthopaedic external fixator has been widely used in the opening or damaged, the myelitic treatment of comminuted fracture, bone does not connect and bone that causes because of wound, but when treating osteomyelitis or have the fracture of osteomyelitis tendency, the problem that existence can not Continuous Perfusion be rinsed medicine, must separately built-in syringe pipe rinse surrounding soft tissue in wound, with dilution or kill bacteria.Usually syringe pipe used is softer because of its quality, easily is subject to surrounding soft tissue and pushes and tube chamber distortion or obstruction, causes a large amount of sepages of wound, needs frequently more change dressings, even has to pull out irrigation drainage tube and stops lavation, causes lavation failed, affects the treatment.
Three, summary of the invention: but the purpose of this utility model be to propose a kind of continous pouring and do not stop up, but the Orthopaedic external fixator that also can carry out the continous pouring administration of topical.
But the purpose of this utility model is achieved in that the Orthopaedic external fixator of continous pouring administration and is comprised of cross bar, staple, cavity staple, fixation clamp four parts, on cross bar, connect two pieces of vertical cavity staples are housed by the fixation clamp interval, in this two nails outside, respectively be connected with a vertical staple by two fixation clamps respectively.One end end of staple, cavity staple all has external screw thread, all has side opening on cavity staple tube wall.The other end of two cavity staples is communicated with tube for transfusion, drainage tube respectively.
Owing to carrying out technique scheme, this fixed support had both solved the distortion of syringe pipe tube chamber and blockage problem, continuous lavation in sustainable many days remains unobstructed, local application controls inflammation or promotes union of fracture by the road again, also increase simultaneously the intensity of exterior fixation bracket, can effectively prevent and treat the generation of osteomyelitis and bone does not connect.
Four, description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:
But Fig. 1 is the Orthopaedic external fixator structural representation of continous pouring administration;
Fig. 2 is cavity staple partial structurtes schematic diagrams;
Fig. 3 is the fixed folder structure schematic diagram.
Legend: 1, external screw thread, 2, side opening, 3, the bone splits position, 4, skeleton, 5, cross bar, 6, the upper clip group, 7, the lower clamping piece group, 8, screw rod, 9, staple, 10, tube for transfusion, 11, the cavity staple, 12, drainage tube.
Five, the specific embodiment:
This utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and practical situation.
Embodiment: as Figure 1-3, but the Orthopaedic external fixator of continous pouring administration is comprised of cross bar 5, staple 9, cavity staple 11, fixation clamp four parts, on cross bar 5, connect two pieces of vertical cavity staples 11 are housed by the fixation clamp interval, in this two nails outside, respectively be connected with a vertical solid staple 9 by two fixation clamps respectively.One end end of staple 9, cavity staple 11 all has external screw thread 1, all has side opening 2 on cavity staple 11 tube walls.The other end of two cavity staples 11 is communicated with tube for transfusion 10, drainage tube 12 respectively.Fixation clamp is by screw rod 8, and upper and lower intermediate plate group 6,7 forms, and every group of intermediate plate is two, and the adjacent one side in each intermediate plate outer end has arc-shaped slot.Have screw on each intermediate plate, screw rod 8 passes screw.Upper and lower intermediate plate group 6,7 arcuate groove are the position relationship of vertical arrangement in space.
During treatment, two staples 9, a cavity staple 11 are passed skeleton 5 from a side at bone splits position 3, another two staples 9, the opposite side of a cavity staple 11 from bone splits position 3 pass skeleton 5.During the lavation medicine, from tube for transfusion 10 input flushing liquors, its side opening 2 on cavity staple 11 flows out, and, through pulp cavity and surrounding soft tissue gap, then from the side opening 2 on another cavity staple 11, flows into tube chambers, by drainage tube 12, is drawn.Rinse completely, at the two cavity staple 11 ports nut of screwing on, tube chamber is lived in deadend.
Above technical characterictic has formed most preferred embodiment of the present utility model, it has stronger adaptability and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, such as hollow screw is used separately or adopts different compound modes to meet the needs of different situations.
