Description
Technical field
Rectangular frame sight is fixed the present invention relates to a kind of two ends, belongs to bone surgery set articles for use field.
Background technology
The patient of limbs fracture is more and more, and wherein most patient needs surgical menopause to treat.Surgical menopause is controlled
Treat fracture and just be unable to do without the implants such as internal fixation device.Conventional material has steel plate and intramedullary nail.For long bone fracture, using steel
Plate fixation belongs to eccentricity and fixed, i.e., fixture deviates itself stress axis of long bone, belongs to a kind of unstable fixed form,
Its fixation is similar to exterior fixing rack, and Interal fixation puts on the pressure of steel plate by screw, makes between steel plate and bone
Certain frictional force is produced to reach fixation.The art formula it is also often desirable to excessively peel off periosteal tissue.And long bone
Nutrition is dependent on outer membrane, particularly periosteum in bone.Because using the patient of the postoperative bone nonunion of Interal fixation, removing steel plate simultaneously
When using Intramedullary nailing and bone grafting instead, although intramedullary nail, which is inserted, will destroy more perimyelis, the bone destroyed when especially expanding marrow
Inner membrance is more, but the healing that Postoperative Bone folding part in the same old way can be good.It can be seen that healing of the periosteum to fracture is extremely important.Stripping
The local blood supply of fracture will be destroyed from excessive periosteum, is that quick healing of bone fracture causes to have a strong impact on, it is seen that in intramedullary nail marrow
Fixed advantage is self-evident.Medullary fixation belongs to central fixation, and intramedullary nail inserts rear axis and long bone where it
Axis is approximately overlapping, and stress loading direction is consistent, and fractures side shearing action is minimized, and belongs to stability preferably interior
Fixed form.Although this fixed form has certain advantage, also there is its weak point.Locking position is mainly manifested in be located at
Intramedullary nail two ends, the floatability that tie point is aimed in distal end is larger, and far-end locking is more difficult, loses the generation of interlocking phenomenon more.Cause
Cantilever has certain elasticity outside sight when being inserted for intramedullary nail, is easily moved to limbs back and forth or left and right, is particularly backward shift forward
It is to cause the main cause of distal end losing lock.In addition, femur marrow interior shape is not quite similar, one has been matched with intramedullary nail
Determine difference, after intramedullary nail is inserted, rivet nut is deformed because of elasticity.It is only near in intramedullary nail between pole bracket sight and intramedullary nail
There is a mere contact tie point at end, and the point is more weak, is the main portions that the outer suspension of sight produces elastic displacement.Have perhaps
Many osteology persons carry out unremitting effort, develop a variety of auxiliary sighting devices to solve the above problems.Such as band ultrasonic mediation
Device, magnetic force mediation device and infrared ray mediation device etc., although these devices also solve some practical problems, but
There is certain losing lock rate.And the sight non-refractory sterilization having, it is easily caused bacterium infection；What is had can only be disposable,
Not only the cost of medical treatment had been added but also unnecessary financial burden is brought to patient.Therefore, inventor develop it is a kind of new
Long bone fracture Medullary fixation sight device（Through type rectangular frame sight）.Cardinal principle is to determine to put down using parallel lines
The solid geometry principle in face, makes all mathematical theories with any two intersect in plane straight line in the plane.Design
Sight has contact point at two with intramedullary nail, and the plane for allowing them to be constituted is in relatively steady state, eliminates as much as
The elastic foundation effect of the outer suspension of sight, makes accurately can smoothly enter marrow by the drill bit and screw of suspension sight hole outside sight
Interior nail two ends lock nail, reach firm interlocking fixing function.
The content of the invention
The present invention there is provided a kind of two ends in view of the above-mentioned problems, fix rectangular frame sight, it is therefore intended that：By this
Invention can precisely complete the far and near pinning drilling of the progress on bone and put tack operation operation.
