Abstract
The utility model relates to a reduction fixator for a scar and a fracture, wherein, the purpose of which is to reach bidirectional regulation, convenient operation, compression, traction, and improved curative ratio of the reposition of tibiofibula fracture. The utility model is mainly formed by that a screw rod is axially connected with fixed rods of a long and a short needle stands and is connected with a support rod in a radial direction. The reduction fixator is in an H shape and is assembled symmetrically up and down via a small needle stand fixed rod. The utility model has the advantages that clinical application tests of 300 cases prove that the curative rate is 100 percents, the utility model is fixed, reliable, portable and flexible, weight is light, needle threading is few and damage is less.
Description
This utility model relates to the trauma fracture reduction fixture device, specially refers to the box-like shin Os Sus domestica of a kind of relevant sets fracture reduction fixator.
In background technology, fracture of tibia and fibula is commonly encountered diseases, the frequently-occurring disease of orthopaedic trauma, accounts for 15%; This sick traditional expectant treatment often is a manual reduction, and plaster fixation or clamping plate are fixed, calcaneal traction treatment, and patient is surplus March of need lying in bed, and treatment cycle is long, is difficult for adjusting, and patient is painful big, and the posterior joint function that heals is poor.Along with doctor colleague's clinical practice, the employing unilateral external fixator that has, structure is one-sided, arm of force frame form, or one-sided support; Characteristics be thread a needle less, both sides pressurization, both sides' traction; Weak point is that pull strength is big inadequately, and pressurization easily becomes the angle; Or the footpath spike is thick, and operation is difficult for regulating.Also have half circle groove shape external fixer in addition, shortcoming be thread a needle many, complex structure, be difficult for grasp; For former frame structure shortcoming is that needle stand is independent, pull needle is yielding.
The purpose of this utility model is to overcome the problem that exists in the above-mentioned technology, develops the compound holder of the box-like fracture of tibia and fibula of a kind of relevant sets, is " H " type fixed support, two-ways regulation, easy to operate, pressurization, traction, improve the fracture of tibia and fibula cure rate that resets, safety, reliable, healing time is short.
This utility model technical solution is as follows:
The needle stand fixed bar, it is characterized in that: minute hand seat fixed bar 1 axially assembles hour hand seat fixed bar 3 through screw rod 2, assembling support bar 4 on screw rod 2, form the fixed mount that resets, two groups of fixed mounts that reset connect through little needle stand fixed bar 5 symmetries, form " H " type fixed mount that resets, on long and short needle stand fixed bar 1 and 3, arrange the adjustable spicule holder 7 of assembling.
This utility model technical solution also comprises:
On the support bar 4 of above-mentioned adjustable assembling length symmetric hole is arranged.
Advantage of the present utility model and effect are as follows:
1. through the biomechanical property experiment, to the modeling of fracturing of each five tool of pig, sheep fresh in vitro tibiofibula, be respectively the big tiltedly type of I type fracture, II type transecting type fracture, the little oblique type of III type or minor spiral type fracture, treat through this utility model reduction fixture device, reach a conclusion: the reduction fixture device stable performance, can opposing from each external force that differs in size of direction differently, guarantee reduction of the fracture effect; Minimum force 30 newton, maximum, force are 1500 newton, and the fracture displacement is at 3.7 millimeters.
2. through clinical practice test, now report 300 examples: the fracture form: oblique type 15 examples of fracturing, screw type and transecting type 285 examples of fracturing, freshness 238 examples of fracturing, old fracture 62 examples; Clinical healing is the shortest to be 28 days, the longest 6 months, about average 10 weeks, and no disunion, patient's knee joint, ankle joint function are all normal, and effective percentage reaches 100%.
3. prove by clinical trial: this utility model is reasonable in design, and it is few to thread a needle, in light weight, damage little, simple in structure, easy operating, reliably fixing, light and flexible, applied widely.
4. by clinical trial: this utility model is regulated flexibly, freely, and span is adjustable, and folding all can be used obese patient's shank, limbs length shorter one, all age group patient freely; It is fixing only can to reset with two pieces of fine needles, and little than other support damage, the patient easily accepts, and reduces medical expense; Both be used for the treatment of fracture of tibia and fibula, can be used for also that humerus is done, positions such as femoral shaft and even hip joint reset fixing; According to practical situation, this utility model and tibia plintlet are used, and effect is better.
This utility model description of drawings is as follows: Fig. 1 is the overall structure sketch map; Fig. 2 is a B-B cut-away view among Fig. 1, and Fig. 3 is an A-A cut-away view among Fig. 1.Above-mentioned number in the figure is described as follows: 1-minute hand seat fixed bar, 2-connecting screw rod, 3-hour hand seat fixed bar, 4-support bar, the little needle stand fixed bar of 5-, 6-screw, 7-spicule holder.
Following adjoint is described in further detail: referring to Fig. 1, long and short needle stand fixed bar 1 and 3 is by 2 assemblings of double end connecting screw rod, socket support bar 4 radially on screw rod 2, and fix by minute hand seat fixed bar 1 end, form the single fixed mount that resets, support bars 4 are assembled with screw 6 in support bar 4 lower ends, and support bar 4 lower ends axially connect long and short needle stand fixed bars 1 and 3 through screw rod 2, symmetry is formed " H " type reduction fixture device up and down.Referring to Fig. 2, this is a spicule holder 7, is assemblied in the hole on long and short needle stand fixed bar 1 and 3, and uniform arrangement or non-uniform arrangement are adorned spicule in the hole on spicule holder 7, adjustable direction.Referring to Fig. 3, support bar 4 has corresponding aperture up and down, adjustable its assembling length.In use, according to different patients, Adjustable bracing bar 4 length, needle stand fixed bar symmetry serves as that axle can littlely rotate with little needle stand fixed bar 5 up and down.
Claims (2)
1, the box-like fracture of tibia and fibula reduction fixture device of relevant sets comprises: the needle stand fixed bar, it is characterized in that: minute hand seat fixed bar 1 axially assembles hour hand seat fixed bar 3 through screw rod 2, assembling support bar 4 on screw rod 2, form the fixed mount that resets, two groups of fixed mounts that reset connect through little needle stand fixed bar 5 symmetries, form " H " type fixed mount that resets, on long and short needle stand fixed bar 1 and 3, arrange the adjustable spicule holder 7 of assembling.
