Description
Technical field
The utility model belongs to medical instrument, is related to sternum fixer, and in particular to contains on a kind of memory alloy wire single-beam
A pair encircles the sternum fixer of arm.
Background technology
The fracture of sternum caused by traffic accident, the reasons such as fall in recent years, fracture of sternum is more serious thoracic injury,
Fracture makes the wall of the chest lose support and soften and cause paradoxical breathing and pendular movement of mediastinum, to seriously affect the breath cycle work(of patient
Can, threat to life.Generally use wire binding, Kirschner wire fixation, Interal fixation and synthetic resin solid in thoracic surgery at present
Surely equal fixators.When doing thoracic surgery, due to the needs treated to patient, it is sometimes desirable to by breastbone along midline incision, hand
Breastbone is tied up or Kirschner wire fixation with stainless steel wire again after the completion of art.When fixed, on the both sides of the intermediate longitudinal cut of breastbone
Punching, puts on steel wire in hole, after breastbone is closed, then steel wire is tied up.Breastbone belongs to flat bone, is easy displacement, and due to lung
The tension of respiration, it is difficult to control the binding dynamics of steel wire.The too loose of binding does not have a fixed effect, binding it is too tight,
Be easy to make steel wire fracture, and longitudinal steel wire is easy to tear on breastbone, using steel wire, steel wire easily loosens, cause breastbone poor healing,
The adverse consequences such as healing delay.After breastbone heals, steel wire is not easy to take out, in some instances it may even be possible to be damaged to infrasternal important device
Official leads to malpractice.Although more firm using Interal fixation, need to drill, is easy to damage retrosternal organ, and body
Interior steel plate is easy to happen cell reaction, needs to carry out second operation taking-up.Although synthetic resin has the characteristics that can absorb, it is not required to
It wants second operation to take fixture, but need to be inserted into ossis when its fixation, be susceptible to infection, and fixed effect is not firm.On
Difficulty is larger when stating existing surgical procedure fixation, and operating time is longer, it is often more important that difficulty is taken out after healing, if operation
It is improper also to hurt internal organs under chest.With the development of science and technology, bone fracture plate for breastbone, such bone plate is made using memorial alloy plank
It, can since plank is formed by forging, rolling, wire cutting although fixing intensity and connective stability is greatly improved
It is uneven there is an interior tissue, the defects of intensity, plasticity, hardness, there may be risk of breakage after such bone plate installation,
It is time-consuming and laborious when being installed in patient body not there is only hidden danger, and dismantling, and the tool that while dismantling needs is various, especially tears open
It needs to pry open claw one by one with special pliers cooperation crowbar after cold compress bone plate when unloading, disassembly process very complicated, time-consuming, deposits
In risk, bone plate could smoothly be dismantled by generally requiring medical staff and having certain operating experience, be needed in some critical cases
Open chest rescue in emergency circumstances, slightly careless manipulation will bring injury to sufferer, serious directly to jeopardize patient's life
Life.
Utility model content
In order to solve the above-mentioned problems in the prior art, the utility model, which provides, a kind of to patient safety and pacifies
The memory alloy for breastbone fixator of dress, convenient disassembly.
The utility model adopts the following technical solution：The breastbone that arm is encircled containing a pair on a kind of memory alloy wire single-beam is fixed
Device, including using single-beam made of a memory alloy wire, the both ends bending inwardly of single-beam is respectively formed one and encircles arm, two rings
Folded arm forms open annular structure, and single-beam stage casing squeezes to form arc-shaped along the direction vertical with plane where open annular structure
Pressure rings.
Further, in open annular structure the equal turning-in in arm end is encircled positioned at opening.
Further, in open annular structure positioned at opening to encircle arm end end rounded.
The utility model has the beneficial effects that：
1, the utility model is made by using a memorial alloy silk material and encircles arm and pressure rings, and encircles arm and pressurization
Ring is integrally formed in horizontal, longitudinal space connection；Two encircle arm is formed by bending open annular structure by memory alloy wire single-beam, knot
Structure is simple, and for whole smooth without corner angle, immobilized patients breastbone is small to blood vesssls and nerves injuries, foreign body sensation is small and human body respiration is overcome to expand
The left and right separation of tension, can persistent pressure, not easily to fall off, safe and reliable.Cold compress is only needed to encircle arm i.e. when being dismantled after patient's recovery from illness
It can open, not needing auxiliary tool can easily take out, simple and efficient to handle, substantially reduce operative cycle, thoroughly solve
Safety is poor, plate forming product easy fracture, and the problem for having crackle, dismounting cumbersome is suitable for the smaller patient of wound.
2, pressure rings are squeezed the strength and stability that the back of a bow can be effectively increased in arc-shaped, memory alloy wire by single-beam stage casing
The molding pressure rings of material and internal contact area are few, reduce and are blocked to the blood fortune of breastbone, are conducive to breastbone revascularization and breastbone
Healing cycle is shortened in the soft tissue blood circulation in region.
3, the utility model encircles arm and pressure rings are memorial alloy silk material, and silk material cross section is more than plate product, resists
It tensile strength and encircles power, toughness and fatigue resistance and is obtained for prodigious raising, it is fixed not easy to break after installation.
4, arm and pressure rings are encircled in horizontal, longitudinally disposed, it is easy to install, it is fixed after installation, lower fracture of sternum significantly
Operating difficulty avoids respiratory movement that later stage fixture is caused the generations such as to loosen, can restore thorax shape rapidly, hence it is evident that mitigate pain,
The complication such as lung inflammation, atelectasis are reduced to occur.
5, encircle that arm end end is rounded, the friction to pleura is reduced after installation to stimulate, and general patient no longer needs to after use
Chief minister's lung ventilator, shortens the hospital stays, improves the quality of living, and has restored labour to greatest extent, meets human body to implantation
The requirement of material, histocompatbility is good, and wear-resisting, corrosion-resistant.
6, the utility model has the function of unique " memory ", encircles arm and is formed by bending by memory alloy wire single-beam, is encircled
The equal turning-in in arm end forms lasting self-pressurization annular " cohesive force " after rewarming and provides good power for union
It learns and ensures, postoperative fracture end is not easy rotation displacement.
7, simple using the method and process of the utility model, formed product is fast, the product of preparation is preoperative when in use only to be needed
Prepare disinfection ice water, is carried out according to fracture and type selection corresponding length, curvature moulding.It is big according to intercostal size in art
The fixator of small and classification of fracture selection suitable dimension.
