Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Minimally invasive spine nail 100 can be usually used cooperatively with spine nail casing.Minimally invasive spine nail 100 is in spine nail casing
Lower screw in of effect needs fixed backbone both ends, and then, wearing rod iron on minimally invasive spine nail 100 makes multiple bone screws become one
A entirety.
Fig. 1 is please referred to, for a kind of minimally invasive spine nail 100.Minimally invasive spine nail 100 includes the implanting portion for being implanted into bone
11 and the nail arm 12 that is connected with implanting portion 11.
Implanting portion 11, which is provided with, can screw in intravertebral screw thread in order to which backbone is fixedly connected.
The material that implanting portion 11 uses can according to minimally invasive spine follow closely 100 whether need take out and it is different.When minimally invasive
The metal or nonmetallic materials of hard can be used in the occasion that the needs of spine nail 100 take out.And when minimally invasive spine nail 100 does not need
When taking-up, then the material close with human spine comparison of ingredients or the material that can be metabolized can be used.
Nail arm 12 includes the extension 121 extended in a first direction and the stiffener that one end far from implanting portion 11 is arranged
122.Extension 121 extends in a first direction, and first direction here is generally understood that the axis that minimally invasive spine nail 100 screws in
To.
It is understood that the spine lengths of personal injury are different, then the extension of nail arm 12 is increased in a certain range
Size can expand the scope of application of minimally invasive spine nail 100, have practical significance.The nail arm 12 of minimally invasive spine nail 100 needs
It is as long as possible, however, nail arm 12 is longer, more it is easily deformed in implantation process.
Referring to figure 2., extension 121 includes opposite the first adjutage 1211 and the second adjutage 1212.Two extensions
Arm links together in intersection, or it can be said that the first adjutage 1211 and the second adjutage 1212 are made of one piece.
In the application, stiffener 122 is set in one end far from implanting portion 11 in nail arm 12, to prevent the deformation of non-magnetic shim arm 12.
Nail arm 12 has the direction that fractures deviateed with first direction.In general, the direction that fractures here can be and first
The vertical direction in direction.When stiffener 122 is connect with extension 121, can anti-non-magnetic shim arm 12 be broken off.
However, perform the operation complete when, at this moment the taking-up that needs to fracture of the extra part of extension 121 then needs stiffener
122 separate with extension 121.Between stiffener 122 and the extension 121 formed guide channel 123, so as to stiffener 122 with
Extension 121 separates.
In order to enable stiffener 122 is separated with extension 121, special cutting tool can be used.Minimally invasive spine nail 100
It is implanted into along first direction, at least one direction of the axial and circumferential of guide channel 123 in a first direction has separation.At this
Apply in a kind of preferred embodiment provided, the axial and circumferential both direction of guide channel 123 in a first direction all has slot
Spacing.
In order to enable the connection that operation is completed between preceding stiffener 122 and extension 121 keeps comparable intensity, and in hand
It after the completion of art, is separated convenient for stiffener 122 with extension 121, stiffener 122 has the overlap joint foot for being overlapped in extension 121
1221.Overlap joint foot 1221 can adjust stiffener 122 and 121 liang of extension by the way that the area being overlapped with extension 121 is arranged
Bonding strength between person.
In another preferred embodiment provided by the present application, overlap joint foot 1221 is in tip-angled shape.Specifically, tip-angled shape
It can make arc wedge angle, triangle wedge angle etc..
Referring to figure 3., for the ease of the entrance of cutting tool, stiffener 122 is in the end thickness extended in a first direction
It is gradually reduced.Further, extension 121 is arranged in the part for the end that the correspondence stiffener 122 extends in a first direction
There are guide openings 1213.
Stiffener 122 brings injury to operator in order to prevent, and stiffener 122 is in the terminal edge extended in a first direction
In arc-shaped.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
