The circumference enough realizing cranium basin connecting rod 1 is mobile, additionally it is possible to ensure skull ring for fixing 2 and the intensity of basin bone ring for fixing 3.
It addition, be provided with the chute 21,31 of circumference, described bolt on described skull ring for fixing 2 and basin bone ring for fixing 3
10 offset with described chute 21,31 inwall.Wherein, described chute 21,31 can be arranged on described skull ring for fixing 2 and described basin
On the inner and outer wall of bone ring for fixing 3, it is mounted on bolt 10 in the both sides of described peristome 91 simultaneously.It is of course also possible to only
In described skull ring for fixing 2 and the side of described basin bone ring for fixing 3, such as on inner side or outside, it is provided with chute 21,31,
In the corresponding side of described peristome 91, the bolt 10 relative with described chute 21,31 is installed simultaneously.
In the present embodiment, based on easy to operate consideration, described chute 21,31 is arranged on described skull ring for fixing 2 He
On the outer wall of basin bone ring for fixing 3, described bolt 10 is arranged on the opening in the outside of described skull ring for fixing 2 and basin bone ring for fixing 3
On portion B91.
It addition, the connection of described cranium basin connecting rod 1 and described base 9 can be any, such as welding, bolt are even
Connect, hinged or splicing etc..In the present embodiment, based on the consideration being easy for installation and removal, described base is provided with screw thread
Via 92, is provided with screw thread at the both ends of described cranium basin connecting rod 1, the upper end of the most fixed bar 11 and described
The bottom of the most fixing bar 12 is provided with screw thread, and described cranium basin connecting rod 1 is by nut 13 and the screw thread via on described base
92 are connected.
Use the cranium basin connecting rod assembly of the present embodiment, it is possible to cranium basin connecting rod 1 can be done along wearer's body periphery
It is adjusted circumferentially, it is possible to make adjustable stabilizing brace can be applicable to the patient of different body types, and enable to wearer
That wears is more comfortable.
The cranium basin connecting rod assembly for adjustable stabilizing brace in the present embodiment, when mounted, can be in advance by described
Base 9 is connected with described skull ring for fixing 2 and basin bone ring for fixing 3, base 9 He being wherein arranged on described skull ring for fixing 2
It is arranged on base 9 one_to_one corresponding on described basin bone ring for fixing 3, more described adjusting nut 5 is placed on described upper regulation bearing 6
Two boss 61 between, and upper regulation bearing 6 and adjusting nut 5 are sleeved on upper fixing bar 11, described adjusting nut 5 passes through
External thread rotary on upper fixing bar 11 is on fixed bar 11, the most again by described lower regulation bearing 8 and upper fixing bar 11
Connect, the bottom of upper fixing bar 11 is placed in the installing hole 81 of described lower regulation bearing 8, and use steady pin 82 to lower
Joint bearing 8 and upper fixing bar 11 link together.Then fixed bar 11 and described lower fixing bar 12 are passed through spiral shell respectively
Female 13 are connected, finally by described with the screw thread via 92 on the base 9 on the base 9 on skull ring for fixing 2 and basin bone ring for fixing 3
The upper end of the most fixing bar 12 is connected, the most again by lower solid with the peristome A62 of described upper regulation bearing 6 by lock-screw 7

Tightly.In whole installation process, only need a setter can install in 3-10 minute.
During wearing, the position of skull connecting rod 1 can be regulated according to the difference of the body type of wearer, in regulation
Time, only need to unscrew the bolt 13 being arranged on described base 9 so that fixed bar 11 can be along described skull ring for fixing 2 weeks
To movement, described lower fixing bar 12 can be mobile along described basin bone ring for fixing 3 circumference, until moving to most suitable position, then will
Described bolt 13 is tightened so that described bolt 13 and chute 31 phase on the chute 21 on skull ring for fixing 2 and basin bone ring for fixing 3
Fix to realizing position.
In use, adjustable stabilizing brace just be dependent on regulate cranium basin connecting rod 1 effective length go gradually to rectify
Just with the condition of illness such as the scoliosis for the treatment of wearer and deformity, so in art, can be according to different operating stage to cranium basin
Connecting rod 1 is adjusted, and when regulation, can go to precalculate according to the treatment situation of wearer needs the length variable of regulation to be
How much, it is adjusted the most again.First the lock-screw 7 on lower regulation bearing 8 is unscrewed so that lower fixing bar 12 can be under described
Slide in the clamp port 82 of regulation bearing 8, then rotate and be positioned at the adjusting nut 5 on fixing bar 11 so that described upper regulation
Under bearing 6 drives, fixing bar 12 moves relative to upper fixing bar 11, and can be according to the quarter arranged on lower fixing bar 12
Degree 4 amounts of control and regulation, till being adjusted to precalculated length variable, then by described lower regulation bearing 8
Lock-screw 7 is locked so that lower fixing bar 12 is clamped in described clamp port 82, to prevent the effective length of cranium basin connecting rod
Change.So far, the effective length regulation of cranium basin connecting rod 1 is complete.Whole regulation process only needs a doctor at 1-8 minute
In can complete, and adjusting position is convenient, and during regulation can clearly, be visually known and regulate length, it is possible to once
Regulation puts in place, improves efficiency.Certainly during wearing, also can carry out the regulation of the effective length of cranium basin connecting rod 1.
To sum up, the cranium basin connecting rod assembly for adjustable stabilizing brace of the present embodiment is used so that adjustable fixing
Brace easier for installation, save time, improve the efficiency of installation.Realize being adjusted circumferentially of cranium basin connecting rod so that Yi Shengke
Build situation according to wearer goes to regulate adjustable stabilizing brace, improves the scope of application of adjustable stabilizing brace.In art
Time can convenient, regulate the effective length of cranium basin connecting rod with saving time.Save cost of labor.Improve cranium basin connecting rod
Intensity, improve stability and the reliability of installation.Ensure cranium basin connecting rod and skull ring for fixing and basin bone ring for fixing has
The locking of effect ground, improves the stability of connection.
