Abstract
The utility model discloses a kind of devices for the correction of the shin bone broken ends of fractured bone line of force, including loop bar and support rod, tapered end is arranged in one end of the loop bar, mounting hole is arranged in the other end, internal screw thread is set in mounting hole, and external screw thread is arranged in described support rod one end, and tapered end is arranged in the other end, using connection is threadedly engaged between the loop bar and support rod, support rod is made to be screwed in the mounting hole of loop bar.The utility model is by being respectively inserted into the tapered end of loop bar and support rod far and near bone stump, rotate loop bar or support rod, the length of appropriateness adjustment loop bar and support rod, extend line of force device, it by bone stump front and back and lateral displacement correction, and is auxiliarily fixed, maintains to reset, the case where avoiding the occurrence of simple naked eyes or judging line of force error by hand, cause bone stump that can not fix and shift again；Present apparatus structure is simple, and low manufacture cost is easy to use, and correction, good fixing effect improve success rate of operation and postoperative limb function recovery effects.
Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to a kind of easy to use, correction and good fixing effect
For the shin bone broken ends of fractured bone line of force correction device.
Background technique
In the post-operative recovery of orthopaedics tibial surgical, it is limited by patient itself and external environmental factor, patient is in chronic bone
Marrow is scorching, often protracted course of disease in the case where infection of bone after Infected nonunion and wound, need to carry out debridement repeatedly to wound, cause
Often there is a bone defect after focal cleaning.Due to infection and bone defect healing difficulty is big, the period is long, brings huge pain to patient's body and mind
Hardship is a great problem for perplexing orthopedist.To solve the problems, such as infection and bone defect, spy uses thorough debridement combination support arm
The method that bone moves art, but the operation method needs to adjust the bone stump line of force after removing inactivation bone, the line of force well can just make
It is accurate to line during Limb lengthening, it avoids bone stump from the case where can not fixing and shifting again occur, operation is caused to be lost
It loses；Currently, correcting the traditional mode of the line of force is the concrete condition that patient empirically judges patient's bone stump during surgery, in conjunction with
The data that C arm is had an X-rayed repeatedly carry out power Line To Line to patient's bone stump, and this method error is larger, easily occur judging that the line of force is missed
Difference causes bone stump that can not fix and the problem of shift again, secondly, post-operative recovery is poor, serious influence limbs of patient function
Recovery.
Therefore, a kind of instrument for being conducive to bone stump in art to line is developed, ensures that successful surgery is that the prior art is overcome to lack
Sunken key.
Utility model content
The utility model is intended to provide a kind of easy to use, and correction and good fixing effect are corrected for the shin bone broken ends of fractured bone line of force
Device.
Purpose of the utility model is realized as follows: including loop bar and support rod, taper is arranged in one end of the loop bar
Mounting hole is arranged in end, the other end, and internal screw thread is arranged in mounting hole, and external screw thread, other end setting is arranged in described support rod one end
Tapered end makes support rod be screwed in the mounting hole of loop bar using connection is threadedly engaged between the loop bar and support rod.
The utility model has the advantages that the utility model is by being respectively inserted into the tapered end of loop bar and support rod far and near bone stump, rotation
Pivoted housing bar or support rod, appropriateness adjust the length of loop bar and support rod, extend line of force device, and bone stump front and back and lateral displacement are rectified
Just, it and is auxiliarily fixed, maintains to reset, avoid the occurrence of simple naked eyes or judge line of force error by hand, cause bone stump that can not fix
The case where shifting again；Present apparatus structure is simple, and low manufacture cost is easy to use, and correction, good fixing effect improve hand
Art success rate and postoperative limb function recovery effects.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of loop bar in the utility model；
Fig. 3 is the structural schematic diagram of support rod in the utility model；
Figure label: 1 ~ loop bar, 2 ~ support rod, 3 ~ tapered end, 4 ~ mounting hole, 5 ~ external screw thread.
Specific embodiment
With reference to the accompanying drawings 1 shown in 1 ~ 2, a kind of device for the correction of the shin bone broken ends of fractured bone line of force, it is characterised in that: including loop bar
1 and support rod 2, tapered end 3 is arranged in one end of the loop bar 1, and mounting hole 4 is arranged in the other end, be arranged in mounting hole 4 in spiral shell
External screw thread 5 is arranged in line, described 2 one end of support rod, and the other end is arranged tapered end 3, uses between the loop bar 1 and support rod 2
It is threadedly engaged connection, support rod 2 is made to be screwed in the mounting hole 4 of loop bar 1.
The diameter of the loop bar 1 is not less than 1cm.
The diameter of the support rod 2 is not less than 0.8cm.
The length of the loop bar 1 is not less than 4cm.
The length of the support rod 2 is not less than 4cm.
The length of the tapered end 3 of the loop bar 1 and support rod 2 is not less than 0.8cm.
The cone angle size of the tapered end 3 of the loop bar 1 and support rod 2 is 10 ~ 30 degree.
The loop bar 1 and support rod 2 is all made of entity or hollow rod body is made.
The tapered end 3 is conical structure, facilitates insertion into and realizes fixation in bone stump.
The working method of the utility model: it firstly, the bone stump to patient is tentatively cleared up, finds and determines bone stump
Center line；Secondly, the tapered end 3 of loop bar 1 and support rod 2 is inserted into respectively far and near bone stump, make the line of force of far and near bone stump
It keeping on the same line, rotating loop bar 1 or support rod 2, appropriateness adjusts the length of loop bar 1 and support rod 2, struts bone stump,
Before and after broken ends of fractured bone bone stump and lateral displacement is corrected；Continue operation after correction until terminating.
