Nail conductor is got according to described orthopaedics, it is characterized in that, in described sleeve, activity is plugged with inner core, inner core comprises cylindrical shell, the lateral wall of cylindrical shell is connected with the medial wall interference fit of sleeve, integrally be fixedly connected with brace table outside the upper port edge of cylindrical shell, brace table is positioned at above the upper port of sleeve.
Nail conductor is got according to described orthopaedics, it is characterized in that, the described inner core that in described sleeve, activity grafting multilamellar is inside and outside arranged, the lateral wall of nexine inner core cylindrical shell is connected with the medial wall interference fit of outer inner core cylindrical shell, and the brace table of nexine inner core is positioned at above the brace table of outer inner core.
Nail conductor is got according to described orthopaedics, it is characterized in that, this orthopaedics is got nail conductor and is also comprised auxiliary sliding sleeve, up and downly in auxiliary sliding sleeve be plugged with support bar, the sidewall thread of auxiliary sliding sleeve is connected with and auxiliary sliding sleeve can be made to be positioned at auxiliary positioning bolt on support bar, integrally be fixedly connected with support set outside auxiliary sliding sleeve, the free end activity of described lateral adjustments bar is plugged in support set; Described submounts is distributed with the slot of multiple opening upwards to lower recess, and support bar lower end is plugged in one of them slot.
Get nail conductor according to described orthopaedics, it is characterized in that, described submounts is fixedly connected with liner, and liner upper surface forms the groove of arc downwards.
Get nail conductor according to described orthopaedics, it is characterized in that, the degree of depth of described slot is 1/3 to 5/6 of described base thickness.
Get nail conductor according to described orthopaedics, it is characterized in that, the degree of depth of described slot is 2/3 of described base thickness.
The present invention is provided with sleeve and inner core, when carrying out internal fixation operation to fracture patient, screwdriver can be inserted sleeve or inner core, can guide screwdriver with this, spacing, avoid screwdriver in the process of operation disorderly to shake and screw slippage, use safe and reliable, operation is simple.

Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As Fig. 1, Fig. 2 and Fig. 3, shown in Fig. 4, a kind of orthopaedics gets nail conductor, comprise base 12, base 12 side has been hinged and connected vertical adjustment bar 8 by main bolt 9, after main bolt 9 screws tight, vertical adjustment bar 8 is positioned at base 12 side, on vertical adjustment bar 8, relative rotary moveable cover is installed with vertical sliding sleeve 7, the sidewall thread of vertical sliding sleeve 7 is connected with and vertical sliding sleeve 7 can be made to be positioned at vertical bolt 6 on vertical adjustment bar 8, the inner end of vertical bolt 6 withstands on vertical adjustment bar 8 side, vertical bolt 6 side is integrally fixedly connected with lateral adjustments bar 5, on lateral adjustments bar 5, relative rotary moveable cover is installed with horizontal sliding sleeve 3, the sidewall thread of horizontal sliding sleeve 3 is connected with and horizontal sliding sleeve 3 can be made to be positioned at located lateral bolt 4 on lateral adjustments bar 5, the inner end of located lateral bolt 4 withstands on lateral adjustments bar 5 side, be rotatably connected outside horizontal sliding sleeve 3 sleeve 1 relatively, sleeve 1 is positioned at above base 12.Rotating vertical adjustment bar 8, lateral adjustments bar 5 and horizontal sliding sleeve 3 and sleeve 1 by regulating, the angle and direction of sleeve 1 can be controlled, make screwdriver just to screw, to operate.
In described sleeve 1, activity is plugged with inner core 2, and inner core 2 comprises cylindrical shell, and the lateral wall of cylindrical shell is connected with the medial wall interference fit of sleeve 1, and be integrally fixedly connected with brace table 17 outside the upper port edge of cylindrical shell, brace table 17 is positioned at above the upper port of sleeve 1.
In the present embodiment, the described inner core 2 that in described sleeve 1, activity grafting multilamellar is inside and outside arranged, the lateral wall of nexine inner core 2 cylindrical shell is connected with the medial wall interference fit of outer inner core 2 cylindrical shell, and the brace table 17 of nexine inner core 2 is positioned at above the brace table 17 of outer inner core 2.The setting of inner core 2 can adapt to the use needs of different model screwdriver.
In order to strengthen stability in the large during operation, this orthopaedics is got nail conductor and is also comprised auxiliary sliding sleeve 15, up and downly in auxiliary sliding sleeve 15 be plugged with support bar 13, the sidewall thread of auxiliary sliding sleeve 15 is connected with and auxiliary sliding sleeve 15 can be made to be positioned at auxiliary positioning bolt 14 on support bar 13, integrally be fixedly connected with support set 16 outside auxiliary sliding sleeve 15, the free end activity of described lateral adjustments bar 5 is plugged in support set 16; Depression that described base 12 faces down is distributed with the slot 18 of multiple opening upwards, and support bar 13 lower end is plugged in one of them slot 18.After the angle and direction of sleeve 1 regulates location, then it is fixing to carry out support to the free end of lateral adjustments bar 5, more effectively avoids small rocking in operation, is conducive to carrying out smoothly of operation.
Described base 12 is fixedly connected with liner 10 above, and liner 10 upper surface forms the groove 11 of arc downwards, and during operation, patient can suffering limb be placed in groove 11, adds the comfort level of patient during operation.
The degree of depth of described slot 18 is 1/3 to 5/6 of described base 12 thickness, and in the present embodiment, the degree of depth of described slot 18 is 2/3 of described base 12 thickness.The thickness direction of slot 18 non-through base 12 is arranged, and only need have certain degree of depth, and such guarantee support bar 13 inserts rear steadily firm.
