Embodiment
As shown in Fig. 1 to one of 3, apparatus of the present invention are used to carry out the pedicle nail for being implanted into the both sides of backbone 5 laterally to fix,
It include a pair be used for be oppositely arranged on the both sides of backbone 5 contiguous block 1, be located in respectively a pair of bottoms of contiguous block 1 and with backbone 5
The pedicle nail of both sides（It is not shown）A pair of the head rods 2 being fixedly connected and two ends are located in a pair of contiguous blocks 1 respectively
In the middle part of vertical direction and by the second connecting rod 3 of two lateral connections of contiguous block 1, described head rod 2 and second is connected
The projection of the in the vertical direction of bar 3 is mutually perpendicular to, and the described correspondence of contiguous block 1 head rod 2 wears position provided with running through
The first through hole 11 of the both sides of contiguous block 1, the position that wears of the second connecting rod 3 of correspondence of contiguous block 1 is provided with through the both sides of contiguous block 1
Second through hole 12, the upper end of the contiguous block 1 is provided with the circular fixing groove 13 connected with the second through hole 12, the side of the fixing groove
Wall is provided with helicitic texture and is threaded with the fastening bolt 4 that the second connecting rod 3 is fixed for abutting.
In order to enable head rod 2 to be fixed on by firm wear in contiguous block 1, further, described the
One through hole 11 is located in contiguous block 1 for the home position of arc-shaped through-hole and the arc-shaped through-hole.
Further, described contiguous block 1 is provided with U-shaped inner fovea part 14 positioned at two side positions that the second through hole 12 is worn.
Further, described contiguous block 1, which is located above two side positions that first through hole 11 is worn, is provided with the first extension slot 15,
The first described extension slot 15 is connected with the through hole 12 of first through hole 11 and second.
Clamping, which is carried out, for the ease of operating forceps places contiguous block 1 and the deadweight for reducing contiguous block 1 and volume, further, institute
The fixing groove 13 for stating the upper end of contiguous block 1 is prolonged along the direction both sides that wear of the second connecting rod 3 provided with the side of contiguous block 1 second is extended to
Stretch groove 131.
In order that obtaining the volume of fastening bolt 4 can further reduce to be adapted to the requirement of Minimally Invasive Surgery, and further, institute
State the whole periphery that the upper end of fastening bolt 4 is arranged at fastening bolt 4 for the helicitic texture of interior hexagonal structure and fastening bolt 4
