Abstract
The utility model belongs to a fixed square block for a percutaneous pedicle screw used for the internal fixation operation of the percutaneous pedicle screw in clinical. The existing fixed block for the orthopedic internal fixation of the spinal percutaneous pedicle screw is universally unstable in fixation, hard to perform the good orthopedic surgery and restoration, inconvenient for surgical operation, and bad for the recovery of a patient. The fixed square block for the percutaneous pedicle screw is characterized in that a threaded arc plate is machined at the upper part of the fixed square block for the percutaneous pedicle screw, a sphericity-adjustable nail plate corner pedicle screw groove is machined at the lower part of the fixed square block for the percutaneous pedicle screw, a fixed connecting plate is machined at the left side of the fixed square block for the percutaneous pedicle screw, and a through hole and a groove are machined on the fixed connecting plate.
Description
Technical field:
This utility model belongs to the employed a kind of percutaneous cervical arc root screw fixed blocks of a kind of percutaneous cervical arc root screw internal fixation operation of clinical medicine, specifically is applied to patient's spinal column percutaneous cervical arc root screw internal fixation.
Background technology:
For the employed fixed block of the orthopedic internal fixation of spinal column percutaneous cervical arc root screw, ubiquity fixing insecure at present, is difficult to carry out good orthopedic and reset, and the operation technique inconvenience influences rehabilitation of patients.
The utility model content:
The purpose of this utility model just is to overcome above-mentioned shortcoming, and a kind of percutaneous cervical arc root screw fixed blocks that provides.
This utility model is achieved in that a kind of percutaneous cervical arc root screw fixed blocks, by the adjustable nail-plate of sphere angle LOCATION OF PEDICLE SCREW FIXATION plate, stricture of vagina tooth arc plate, stricture of vagina tooth locking plate, fixed connecting plate, spherical adjustable nail-plate angle pedicle screw groove, spherical adjustable nail-plate angle pedicle screw and be connected and fixed rod and form, it is characterized in that: be processed with stricture of vagina tooth arc plate on the top of percutaneous cervical arc root screw fixed blocks, be processed with spherical adjustable nail-plate angle pedicle screw groove in the bottom of percutaneous cervical arc root screw fixed blocks, the left side in the percutaneous cervical arc root screw fixed blocks is processed with fixed connecting plate, on fixed connecting plate, be processed with through hole, this through hole is used for installation and is connected and fixed rod, is processed with groove at the middle part of fixed connecting plate.
Sphere of the present utility model is adjustable, and nail-plate angle pedicle screw is mounted on the spinal vertebral of human body, on the pedicle screw of the adjustable nail-plate of sphere angle, be installed in the pedicle screw groove of spherical adjustable nail-plate angle, in the hole of fixed connecting plate, be equipped with and be connected and fixed rod, on stricture of vagina tooth arc plate, stricture of vagina tooth locking plate is installed, on stricture of vagina tooth locking plate, nut is installed, the angle of spherical adjustable nail-plate angle pedicle screw in the pedicle screw groove of the adjustable nail-plate of sphere angle is adjustable, and angle mixes up the back and fixes by stricture of vagina tooth locking plate and nut.

The specific embodiment:
Now describe embodiment of the present utility model in conjunction with the accompanying drawings in detail.
This utility model is spherical adjustable nail-plate angle LOCATION OF PEDICLE SCREW FIXATION plate 1, stricture of vagina tooth arc plate 2, fixed connecting plate 3 and the spherical adjustable nail-plate angle pedicle screw groove 4 that the titanium alloy material of an integral body is processed into.Spherical adjustable nail-plate angle LOCATION OF PEDICLE SCREW FIXATION plate 1 is processed with circular groove, be mainly used in spherical adjustable nail-plate angle pedicle screw 6 is installed, the angle of spherical adjustable nail-plate angle pedicle screw 6 in the groove of circle is adjustable, stricture of vagina tooth arc plate 2 is processed into the radian of sawtooth pattern, on stricture of vagina tooth arc plate 2, stricture of vagina tooth locking plate 7 is installed, be used to lock the setting angle of spherical adjustable nail-plate angle pedicle screw 6, fixed connecting plate 3 is processed with through hole, be used for installing and be connected and fixed excellent 5, middle part at fixed connecting plate 3 is processed with groove, significant feature is with to be connected and fixed rod 5 well fixing, be connected and fixed rod 5 and adopt the titanium alloy material processing and fabricating, its front end is processed into tapered, when undergoing surgery, earlier two the adjustable nail-plate of sphere angle pedicle screws 6 are inserted on patient's the spinal vertebral, again two a kind of percutaneous cervical arc root screw fixed blocks of the present utility model are installed in respectively on the spherical adjustable nail-plate angle pedicle screw 6, be installed in a kind of through hole of percutaneous cervical arc root screw fixed blocks being connected and fixed rod 5 again, again stricture of vagina tooth locking plate 7 be installed in stricture of vagina tooth arc plate 2 above, adjust angle and again nut screwing clamping got final product.
This utility model is applicable to that percutaneous cervical arc root screw internal fixation pedicle screw-rod is orthopedic, spinal fixation bone, deformity or degenerative disease etc.
In sum, this utility model uses technology simple, and operating time is short, has promptly overcome universal screw and has been difficult to carry out the good orthopedic and restriction that resets, and guarantees that again a fixed angle nail seat pedicle screw has advantage orthopedic, that the strength that resets is strong.
