It is illustrated for anatomical form intramedullary nail.It should be noted that this case is equally applicable to the first threaded hole of other quantity and second
The intramedullary nail of threaded hole, in addition this humerus anatomical form intramedullary nail material is preferably titanium alloy or pure titanium, selects stainless steel certainly
Etc. materials the technical program may be implemented, should all belong to scope of the present application.
In conjunction with shown in Fig. 1-3, humerus anatomical form intramedullary nail, an including main nail 100,100 distal ends of main nail open up there are two the
One threaded hole 110, the first threaded hole 110 are axially perpendicular to main nail 100 axially, this two the first threaded holes 110 are axially distinct, also
Include the first screw 300 being used cooperatively with the first threaded hole 110,100 proximal ends of main nail offer the second different spiral shell of 3 directions
Pit 120, each second threaded hole 120 are axially perpendicular to main nail 100 axially, further include being used cooperatively with the second threaded hole 120
The second screw 200,200 tail end of the second screw, which sets to the concave, is formed with a cavity 210, and 210 bottom opens outward of cavity is equipped with the
Three threaded holes 220, the axial angle between 200 axial direction of the second screw of third threaded hole 220 is 15 °~60 °, 210 side of cavity
It is uniformly distributed to there are multiple sewing holes 230,210 top of cavity to be recessed with the first positioning groove 240.
Further, further include the third screw 400 being used cooperatively with third threaded hole 220,400 tail end of third screw supports
It is held in inside cavity 210, third screw 400 is self tapping self-drilling screw.
Further, 100 sides of main nail are recessed with the escape groove 130 of evacuation third screw 400.
Further, main nail 100 offers the 4th threaded hole 140 in the middle part of proximal end, the 4th threaded hole 140 it is axial with
Angle is 30 °~70 ° between 100 axial directions of main nail, further includes the long spiro nail 500 for coordinating the 4th threaded hole 140 to use.
Further, main nail 100 is a hollow cylinder, and 100 distal ends of main nail are formed with tip.
Main nail is facilitated to import.
Further, the second positioning groove 150 is offered in 100 proximal faces of main nail.
Facilitate fixed main nail.
Further, further include the proximal end plug of cooperation 100 proximal faces of main nail.
Further, the second screw 200 is uniformly recessed with cutting edge 250 in 210 lower section of cavity.
Cutting edge can play the role of self tapping from brill so that the second screw is conveniently screwed into bone.
Doctor is according to the corresponding main nail (such as left and right, length etc.) of the fracture situation of patient selection, early period, post-operative operation
As the operation of conventional intramedullary nail, the difference is that operation mid-term operation, specific as follows：
1, doctor is first screwed into the first screw of the first threaded hole of main nail distal end by normal operation, then regards the fracture of patient
Situation is screwed into the second screw by instrument in the second threaded hole of main nail proximal end, and corresponding length is selected according to bone thickness
Second screw, the main escape groove nailed on when the second screw is screwed into deeper for making the third screw being screwed into below avoid main nail side
Face.
2, doctor's angle of third threaded hole on the second screw is screwed into third screw, and two nails are crossed as certain angle
Degree, preferably 30 °, strengthens the fixation of intramedullary nail and bone, third screw highly effective to the patient with osteoporosis
Nail tip is designed to that self tapping from brill form, reduces the danger of secondary punch；Head is to immerse oneself in design, and becomes fully hidden in the second screw
Inside cavity, reduce the risk of impact.
3, the 4th screw thread orifice angle is 30 °~70 °, for being screwed into a long spiro nail, preferably 50 °, medial support enhancing
The stability of synosteosis art and the safer fixation for allowing proximal humeral fracture, especially inside crush the bone of (Inner turns over type)
Folding.
4, the sewing hole of the second screw head bundlees bone and muscle, while shoulder sleeve can be made more may be used for passing through suture
The attachment leaned on, the first positioning groove are positioned for instrument.
5, the second threaded hole of main nail proximal end is divided into different angle, and doctor can be all or part of according to the actual conditions of patient
It is screwed into the second screw, selective function substantially increases operability when surgical, greatly reduces operation wind
Danger.
6, the effect of proximal end plug is to block hole (the main nail implantation and when taking-up and device when the hole is operation of main nail proximal face
Tool connection), it does not allow tissue to grow into the inside, blocks screw thread etc., avoid increasing trouble to later taking-up.
It should be noted that herein, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation
In any actual relationship or order or sequence.Moreover, the terms "include", "comprise" or its any other variant are intended to
Non-exclusive inclusion, so that the process, method, article or equipment including a series of elements is not only wanted including those
Element, but also include other elements that are not explicitly listed, or further include for this process, method, article or equipment
Intrinsic element.In the absence of more restrictions, the element limited by sentence "including a ...", it is not excluded that
There is also other identical elements in process, method, article or equipment including the element.
The above is only the specific implementation mode of the application, it is noted that for the ordinary skill people of the art
For member, under the premise of not departing from the application principle, several improvements and modifications can also be made, these improvements and modifications are also answered
It is considered as the protection domain of the application.
