Abstract
The rumpbone longitudinally fractured can either be fixed the present invention relates to a kind of, sacral nerve branch will not be made to receive the fixing means that the rumpbone of compressing is longitudinally fractured again, after rumpbone side is longitudinally fractured, a rumpbone pedicle screw is being fixed positioned at the another side of rumpbone, and fix an iliac screw respectively on the ilium positioned at rumpbone both sides, three screw afterbodys should be laterally positioned on a horizontal line after the reduction of the fracture, then strut with pitman lateral connection and suitably fixation.Advantage：Avoid sacrum porose area fracture with compressive sacral nerve is caused to oppress, fundamentally solve the defects of background technology is present.
Description
Technical field
The rumpbone longitudinally fractured can either be fixed the present invention relates to a kind of, again sacral nerve branch will not be made to receive pressure
The fixing means that urgent rumpbone is longitudinally fractured, belong to medical apparatus application field.
Background technology
At present the vertical shape fixed structure that uses of fracture of rumpbone for：Part is respectively fixedly connected with the ilium of rumpbone both sides,
Then rumpbone is connected with the connector on the ilium of rumpbone both sides by connecting rod, purpose forces position by the tension of connecting rod
Fracture end in rumpbone both sides pressurizes, by fracture end pressurize caused by frictional force reach the mesh of the longitudinal fracture of the sacrum that is fixedly clamped
's.Its weak point：The longitudinal direction fracture of sacral fracture most commonly sacrum porose area.Due to thering is sacral nerve branch to pass in sacrum porose area, and
The pressurization of rumpbone both sides makes sacral nerve branch receive compressing, postoperative usually to produce causalgia, makes patient pain unbearably, very
Pain.
The content of the invention
Purpose of design：The weak point of background technology is avoided, design is a kind of to be consolidated the rumpbone longitudinally fractured
It is fixed, sacral nerve branch will not be made to receive the fixing means that the rumpbone of compressing is longitudinally fractured again.
Design：In order to realize above-mentioned purpose of design.Using three screws（One piece of rumpbone pedicle nail, two pieces of iliums
Screw）It is the technical characteristics of the present invention and horizontal connecting bar moderately struts the design being connected.The purpose so designed exists
In：After rumpbone side is longitudinally fractured, it is distributed in the another side of rumpbone and fixes a pedicle screw and the ilium spiral shell positioned at rumpbone both sides
Nail forms sight alignment after resetting, wherein fracture offside rumpbone pedicle screw and iliac screw be respectively as fixed anchor point,
The stabilization of horizontal connecting bar is determined with the principle of 2 points of decision straight lines.After the rod follows closely fixed with the ilium for side of fracturing again just no longer
Need fracture end to pass through frictional force caused by pressurization to improve fixed stability, therefore can moderately strut solid without influenceing
Determine effect.The stabilization that its tranverse connecting rod and screw really play according to lever principle, rather than extruding force, therefore avoid to sacrum
The direct compressing of nerve branch, so that postoperative causalgia phenomenon falls below minimum degree.
Technical scheme：The fixing means that a kind of rumpbone is longitudinally fractured, after rumpbone side is longitudinally fractured, another positioned at rumpbone
A rumpbone pedicle screw is fixed in side, and fixes an iliac screw respectively on the ilium positioned at rumpbone both sides, fracture
Three screw afterbodys should be laterally positioned on a horizontal line after reset, then strut with pitman lateral connection and suitably fixation.
The present invention avoids sacrum porose area fracture with compressive and sacral nerve is caused to oppress, fundamentally solve compared with background technology
The defects of background technology of having determined is present.
Brief description of the drawings
Fig. 1 is the fixing means schematic diagram that rumpbone is longitudinally fractured.
Embodiment
Embodiment 1：The fixing means that a kind of rumpbone is longitudinally fractured, after rumpbone side is longitudinally fractured, another positioned at rumpbone
A rumpbone pedicle screw is fixed in side, and fixes an iliac screw respectively on the ilium positioned at rumpbone both sides, fracture
Three screw afterbodys should be laterally positioned on a horizontal line after reset, then strut with pitman lateral connection and suitably fixation.
It follows closely rod technology system prior art, is not described herein herein.
It is to be understood that：Although above-described embodiment is contrasted to the mentality of designing of the present invention, detailed word is retouched
State, but these word descriptions, simply the simple text of mentality of designing of the present invention is described, rather than to mentality of designing of the present invention
Limitation, any combination, increase or modification without departing from mentality of designing of the present invention, each fall within protection scope of the present invention.
Claims (2)
1. the fixing means that a kind of rumpbone is longitudinally fractured, it is characterized in that：After rumpbone side is longitudinally fractured, positioned at the another side of rumpbone
A rumpbone pedicle screw is fixed, and fixes an iliac screw respectively on the ilium positioned at rumpbone both sides, fracture is multiple
Three screw afterbodys should be laterally positioned on a horizontal line behind position, then strut with pitman lateral connection and suitably fixation.
2. the fixing means that rumpbone according to claim 1 is longitudinally fractured, it is characterized in that：Three screw tails after the reduction of the fracture
Portion should be laterally positioned on a horizontal line, and the ilium nail for side of being fractured after connection is that appropriateness is outwards strutted rather than pressurizeed.
