Acid esters, polyvinyl alcohol, aromatic polyester, polysiloxanes, polyformaldehyde, polyether-ether-ketone etc..
In addition, also include above-mentioned material and the composite medical material of the compound preparation of nonmetallic inorganic medical material, it is nonmetallic
Inorganic biocompatible materials, such as hydroxyapatite, tricalcium phosphate etc..
The thickness of the plate body 1 is 2mm~5mm.
Described two diameters of fixing hole 3 are different.Three lock holes 2 diameter is identical.
Cross moment provided in an embodiment of the present invention supports showing for the application of double spike devices when Fig. 2 is treatment fracture of neck of femur
It is intended to.Double applications of the spike devices when treating fracture of neck of femur are supported to the cross moment with reference to Fig. 1-1,1-2 and Fig. 2
It is described in detail.
As shown in Fig. 2 fractured at neck of femur 9.First face 7 of the plate body 1 is bonded with tuberosity part 10, described 3
Locking nail 5 is parallel to each other, is hammered into from the lock hole 2 in the first face 7 of the plate body 1, penetrates shaft of femur 11 and to shaft of femur 11
Offside obliquely downward tilts, and there is external screw thread the front end of three locking nails 5, fixed on the contralateral cortex 12 of shaft of femur 11, so that will
Plate body 1 is fixedly connected with tuberosity part 10.The locking nail 5 can be os integumentale screw.
Two fixing glues 4 hammer into from the fixing hole 3 on the first face 7 of plate body 1, through neck of femur 9 fracture and penetrate
Femoral head 8, femoral head 8 is fixedly connected with neck of femur 9 by described two fixing glues 4.The fixing glue 4 can be cancellous bone
Screw.
In the embodiment of the present invention, there is an external screw thread front ends of described two fixing glues 4, non-threaded in described two fixing holes 3,
For sliding eye.Described two fixing glues 4 are parallel to each other.With the rehabilitation of fracture, the combination for two sections of fracturing can be further close,
Because fixing hole 3 is sliding eye, the fixing glue 4 can be slided to the second face 6 of the plate body 1 under pressure, so as to
Avoid, as fracture rehabilitation, fixing glue 4 penetrate femoral head under pressure, causing the abrasion to facies lunata.
It is alternatively possible to the wooden partition around described two fixing holes 3 is thickeied, so as to which two fixing holes 3 could be formed with
Certain thickness slideway, described two fixing glues 4 are guided to stablize under pressure effectively to the second face 6 of the plate body 1
Slide.
Straight line where fixing glue 4 is with the straight line where locking nail 5 in space intersection.
The embodiment of the present invention reasonably utilizes the support force of the more firm bony structures of near end of thighbone (such as tuberosity part)
Locking nail, fixing glue and plate body are transmitted, the fixation for being stablized the neck of femur fractured.Solves prior art
In merely using three pieces of hollow nails in the treatment of fracture of neck of femur because of failure in treatment caused by osteoporosis the problem of.
Further, since the double spike devices wounds when treating fracture of neck of femur of cross moment support provided in an embodiment of the present invention
Area is small, and operation can greatly alleviate the injury to patient in minimally invasive lower progress.
Proximal humeral fracture refers to greater tubercles of humerus with the fracture of upper bit, and it accounts for the 4%~5% of whole body fracture, accounts for shoulder
The 26% of portion's fracture.Because proximal humeral fracture is multiple, therefore for its treat, fixed and patient's post-operative recovery very
It is important, to avoid leaving secret worry for patient.Proximal humeral fracture is common in the elderly, because the elderly is generally associated with
Serious osteoporosis, easy comminuted fracture, therefore proximal humerus lack effective medial support.In the upper arm to this kind of crowd
When bone fracture site is fixed, through being commonly encountered screw hold deficiency, lacking the problems such as effective inner side mechanical support.
The application of Fig. 3 double spike devices of cross moment support provided in an embodiment of the present invention when being treatment proximal humeral fracture
Schematic diagram.Double spike devices are supported with reference to Fig. 1-1,1-2 and Fig. 3 to the cross moment when treating proximal humeral fracture
Using being described in detail.
As shown in figure 3, greater tubercles of humerus 14 is nearby fractured.First face 7 of the double spike devices of cross moment support
Outside with major tubercle 14 is bonded, and 3 locking nails 5 are parallel to each other, hammer into, wear from the lock hole 2 in the first face 7 of the plate body 1
Enter the body of humerus 15 and tilted to the offside obliquely downward of the body of humerus 15, there is external screw thread the front end of three locking nails 5, right in shaft of femur 11
Fixed in the cortex of side, so as to which plate body 1 be fixedly connected with greater tubercles of humerus 14.The locking nail 5 can be os integumentale screw.
Two fixing glues 4 are parallel to each other, hammered into from two fixing holes 3 on the first face 7 of plate body 1, through major tubercle 14
Neighbouring fracture simultaneously penetrates the head of humerus 13, is fixedly connected with the head of humerus 13 with major tubercle 14 by described two fixing glues 4.
Straight line where fixing glue 4 is with the straight line where locking nail 5 in space intersection.
In the embodiment of the present invention, the diameter of described two fixing glues 4 is different, and respectively the first fixing glue and second is fixed
Nail, wherein the diameter of the first fixing glue is more than the diameter of the second fixing glue.First fixing glue can be that short thread is followed closely, such as
Can be the lag screw of half-thread), second fixing glue can be cancellous bone screw.Described two fixing holes 3 have interior spiral shell
Line, it is fixing hole.
The embodiment of the present invention reasonably utilizes the support force of the more firm bony structures of proximal humerus (such as major tubercle)
Locking nail, fixing glue and plate body are transmitted, the fixation for being stablized the humerus fractured.Solve in the prior art
Screw hold deficiency, lack the problems such as effective inner side mechanical support.
Because cross moment provided in an embodiment of the present invention supports double spike devices wound areas when treating fracture of humerus small,
Operation can greatly alleviate the injury to patient in minimally invasive lower progress.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
Embodiment illustrated herein is not intended to be limited to, and is to fit to consistent with principles disclosed herein and features of novelty
Most wide scope.
