Description
Technical field
This utility model relates to a kind of spinal column nail-plate holder, belongs to orthopaedics fixed apparatus field.
Background technology
In recent years, the sickness rate of spine and spinal cord wound, tumor has the trend that rises year by year.Along with the development of spinal surgery technology and treatment theory, previously comparatively passive palliative treatment just is being transformed into positive rational surgical intervention.At present main internal fixation device is the pedicle nail bar system; although the pedicle nail bar system brings glad tidings for patient and spinal surgeons; but the destruction for canalis spinalis but can't be repaired; spinal cord is lacked protective measure; scar after the operation adhesion compressing spinal cord causes nervous symptoms; though adopted Antiadhesive film, also be the compressing that is difficult to prevent cicatrix.Before this utility model; domestic just like disclosed " pedicle for cervical vertebra arch nail fixing device " patent on April 5th, 2006 by the Wang Chun application; the patent No. is 200520095325.9; this device solves fixation problem; the stable of spinal column played a protective role; its weak point is can't repair destructive canalis spinalis, and spinal cord is lacked protective measure.Therefore design and a kind ofly not only have the pedicle screw-rod system advantage but also can rebuild canalis spinalis protection spinal cord, and the internal fixation device of reasonable price, become the focus of research.
Summary of the invention
The purpose of this utility model is to provide a kind of scientific structure, simple, the reasonable price of processing technology, and has the spinal column nail-plate holder that the pedicle screw-rod system advantage can be rebuild canalis spinalis protection spinal cord again.
This utility model in order to achieve the above object, a kind of spinal column nail-plate holder is provided, constitute by titanium plate (1), pedicle nail (3) and nut (6), it is characterized in that on the surface plate of titanium plate both sides screw hole (2) being arranged, pedicle nail is installed in the screw hole, and nut is fixed together pedicle nail and titanium plate.
This utility model spinal column nail-plate holder is characterized in that titanium plate (1) middle part is arch, and both sides are surface plate, and screw hole is arranged on the surface plate, and the included angle A of surface plate and horizontal plane is 0 °～25 °.The middle part of titanium plate be arch to adapt to the spinal column resemblance, reach the purpose of rebuilding canalis spinalis protection spinal cord, ruined canalis spinalis obtains repairing when making operation, prevents effectively that also scar after the operation adhesion compressing spinal cord from causing nervous symptoms.The surface plate of titanium plate both sides and the included angle A of horizontal plane are 0 °～25 °, be form according to different spinal column pedicles of vertebral arch to select the titanium plate of different angles, make the pedicle nail can be in pedicle of vertebral arch with suitable fixed angle.The specification of titanium plate has multiple, and fibrous root is gone back fibrous root and selected different sizes according to the length of rebuilding canalis spinalis according to the different width specifications of operator individual selection and the specification of both sides surface plate and horizontal plane angle.Rebuild two joint canalis spinalis, its size is little, uses 4 pedicle nails to fix, and rebuilds the above canalis spinalis of three joints, corresponding increase titanium plate length and pedicle nail quantity.
This utility model spinal column nail-plate holder, there is nail platform (4) at the middle part of described pedicle nail (3), and there is lead-in cavity (5) at the center.Correct for guaranteeing that pedicle nail enters the pedicle of vertebral arch angle in implementing operation, the first placement positioning pin of palpus, after positioning needle is placed and is finished, because there is lead-in cavity (5) at the center of pedicle nail, at this moment the lead-in cavity at pedicle nail center need only be aimed at positioning needle, enter pedicle of vertebral arch along positioning needle, can guarantee that pedicle nail accurately locatees.There is nail platform (4) at the pedicle nail middle part, and nail platform diameter can be consistent with screw hole (2) diameter, makes the nail platform screw in and be submerged in the screw hole, and nail platform diameter also can be bigger than the diameter of screw hole, makes the nail platform be fixed on the screw hole top of titanium plate.The nail body of pedicle nail has coarse-pitch thread, and the top also has in-line or criss-cross groove, and the same with common screw is screw-driver slot.This utility model spinal column nail-plate holder, used nut (6) is a hex nut.
The installation method of this utility model spinal column nail-plate holder is: select suitable titanium plate, comprise the specification of width, length and both sides surface plate and horizontal plane angle, the titanium plate is placed on the position that spinal column will be repaired; Positioning needle is hammered into pedicle of vertebral arch from the screw hole of titanium plate; The lead-in cavity of pedicle nail (3) is aimed at positioning needle, pedicle nail is installed along positioning needle; With nut (6) titanium plate and pedicle nail are fixed together; Take out positioning needle and the part that pedicle nail is oversize is wiped out.This utility model spinal column nail-plate device is just installed and is over.
This utility model spinal column nail-plate fixer has following advantage:
1, this utility model spinal column nail-plate fixer structure science, processing technology is simple, and cost of manufacture is relatively low, reasonable price, fixing easily, operation is accurate, quick and safe.
2, this utility model spinal column nail-plate holder; meet body mechanics's characteristic; fixation; this holder can dispersive stress; reduce the generation of internal fixation fracture, not only have the pedicle screw-rod system advantage but also can rebuild canalis spinalis protection spinal cord, prevent that scar after the operation adhesion compressing spinal cord from causing nervous symptoms; reduced the probability that complication takes place, welcome by hospitalized patients.
