Description
Technical field
The invention belongs to medical instruments field, specially a kind of new-type external fixation used for orthopedics tool.
Background technology
Outer fixation is a kind of mode of fracture operation treatment.Modern field of orthopaedics has various external fixator materials, respectively
There are advantage and disadvantage, be not to fix poor reliability in summary, be exactly complex structure, operation is wasted time and energy, while can not assist multiple again
Position fracture, can not coordinate fixed operation outside the closed reduction for realizing fracture end with C-arm X-ray machine.
The content of the invention
A kind of external fixing rack that technical assignment of the invention is directed to above prior art deficiency and provides.
The present invention is for the solution technical scheme that is used of above technical problem：Homing position type external fixing rack, including nail frame, bone
Stuck-module, adjuster are followed closely in the outer fixed nail of folding, nail frame and external fixation of fracture, and described nail frame is by module slide groove portion, irremovable
Fixture block, removable fixture block and fastening swivel nut composition；The fracture site that it is special that module slide groove portion is correspondence is also designed to T-shaped, and
According to manufacture material density, can be made into centre has the tabular of permeability chute, cylindric or flat column；Stuck-module is placed on nail
Frame chute, is slidably adjusted, and external fixation of fracture nail is fixed by stuck-module with nail frame；Two nail framves pass through stuck-module, bone
The outer fixed nail of folding is fixed with nearly distal section of fracturing, and by adjuster active link and fixation, can complete the reset and fixation of fracture
Operation.
Described nail frame is made up of module slide groove portion, irremovable fixture block, removable fixture block and fastening swivel nut, irremovable
Fixture block is integrated with module slide groove portion；Diameter is slightly larger than module slide groove portion after two fixture block pairings, and distal end is the inverted cone of certain taper
Post, near-end is threaded screw rod, and distal end involutory surface is equipped with the hemisphere recess of opening, and it is vertical that trisection is equipped with from opening
Row crack, can more preferable clamping regulator universal ball end, near-end involutory surface is respectively equipped with concavo-convex correspondence braking；Fastening swivel nut tail
Portion is nut portions, and corresponding with the threaded shank after two fixture block pairings, remaining part is cone cylinder, and the inverted cone post with two fixture block pairings is relative
Should.
Described external fixation of fracture nail distal section is the sclerotin fixed position with thread tapping, and proximal segment is diameter identical polished rod,
Tail
Portion is electric drill, twists rotation spanner connecting portion.
Described nail frame is made up of with external fixation of fracture nail stuck-module sliding block, locking nut, tapered sleeve, and sliding block is by rear fixture block
And constituted with its one fix bar；Fix bar near-end is the flat cylinder of two side millings, and distal end is screw rod, and slider designs be it is hollow,
It is outer fixed nail jack；Locking nut feature is that near-end is the bolt hole being relatively large in diameter, and distal end is the less resistance pin-and-hole of diameter；Cone
It is arranged the circular cone column casing of the open and clear mouth for being calculated as certain taper.
Described adjuster is by left-handed ball screw, dextrorotation ball screw, mariages swivel nut, fastening bolt, anti-rotation mandrel group
Into ball screw near-end is equipped with tubular slot, and slot mouthful two side is provided with anti-rotation platform；Anti- rotation mandrel two sides omit that milling is flat to be
Anti- rotation platform；Mariages swivel nut outward appearance：Middle part is cylindric compared with tubbiness, and fastening bolt holes are provided with four sides, and two ends are more elongated
It is cylindric；Anti- rotation mandrel is inserted by the tubular slot that mariages swivel nut is directed at two screw rods, is twisted rotation mariages swivel nut and is completed adjuster
Assembling, clockwise, rotates counterclockwise the adjustable length of mariages swivel nut, and fastening bolt is by the fastening bolt holes pair on mariages swivel nut
The chain-wales of accurate anti-rotation mandrel tighten the fastening that can complete adjuster.
Specific operation technique：Two nail framves follow closely first solid with the nearly distal section of fracture by stuck-module, external fixation of fracture in operation
It is fixed, two nail frame Retracting repositioning fracture are grasped, the bulb of adjuster two is placed into two nail framves remote by adjustment adjuster to appropriate length
End fixture block ball-and-socket, twists and screws solid swivel nut fixation bulb, and the perspective reduction of the fracture of C-arm X-ray machine is good, twists rotation adjuster mariages swivel nut
Pressurization pairing fracture end, tightens adjuster fixing bolt.
The advantage of homing position type external fixing rack：1st, in performing the operation, reduction of the fracture the first two is followed closely frame and is first fixed with nearly distal section of fracturing,
Two nail frame drawings of grasping are easier reseting fracture, and other external fixing racks need fracture end otch, by restorer Retracting repositioning
Fracture, clamp installs external fixing rack after fixing fracture end；2nd, after the reduction of the fracture, can by twisting the fastening swivel nut fixation bulb of rotation two
Fracture site is fixed, and the bolt that other external fixing racks need to twist fixed nail, fixture block and 8 or so, frame of nail outside rotation could be by bone
The end that fractures is fixed, and period exerts oneself inequality, shearing occurs, and fracture site occurs and misplace again, need to unclamp each fixing bolt, weight
New reseting fracture, retightens.
The invention is reasonable in design, easy to use.
