The specific embodiment
Superposing type full-height vertebral body 11 formers as shown in Figures 1 to 3, include stack implanting portion assembly, on the assembly of described stack implanting portion, be connected with apparatus parts, its unusual part is: stack of the present invention implanting portion assembly includes superimposed sheets assembly.Meanwhile, apparatus parts includes interior fixed bar 3, is connected with interior fixed bar 3 on superimposed sheets assembly.Specifically, interior fixed bar 3 outer setting have outer catheter 4, are provided with and control assembly 5 at outer catheter 4 leading portions, control assembly 5 and contact with superimposed sheets assembly.And outer catheter 4 peripheries, stage casing are provided with fixed guide fixed tube 6, are connected with adjusting part on fixed guide fixed tube 6, are provided with separation assembly at outer catheter 4 rears.Consider the convenient degree of use, fixed guide fixed tube 6 and adjusting part can hold outer catheter 4 by also can regulate and control outer catheter 4 enters vertebral body 11 degree of depth.
With regard to preferably embodiment of the present invention one, for the ease of using, superimposed sheets assembly includes superimposed sheets 1 and lower superimposed sheets 2, in upper superimposed sheets 1 and lower superimposed sheets 2, is provided with groove.Thus, when upper superimposed sheets 1 and the involutory assembling of lower superimposed sheets 2, groove is merged into connecting groove.Corresponding with it, to hold on assembly and be provided with adapter 10, connecting groove contacts with adapter 10.
Further, regulate for the ease of using, the adjusting part of employing includes regulating sleeve 12, and regulating sleeve 12 is movably arranged on fixed guide fixed tube 6 peripheries, is connected with lock sleeve 13 on regulating sleeve 12.Certainly, for convenient for control, accurate positioning, regulating sleeve 12 is provided with screw thread with lock sleeve 13 inwalls, is provided with screw thread at fixed guide fixed tube 6 outer walls, and thus, regulating sleeve 12, lock sleeve 13 are threaded with fixed guide fixed tube 6.Like this, regulating sleeve 12 can be connected with fixed guide fixed tube 6 and regulate connecting length, and lock sleeve 13 can be realized screw-threaded coupling.
Again further, for the ease of accurate separation, the separation assembly of employing includes handle 14, and described handle 14 is provided with clamp nut 15, is connected with spacing ring 8 at clamp nut 15 by clutch nut 9.Meanwhile, on spacing ring 8, be connected with clutch lever 7.Certainly,, for the more effective work of clutch nut 9, be provided with screw thread at outer catheter 4 leading portions.Like this, in the time of practical operation, clamp nut 15 can be realized handle 14 and be connected with outer catheter 4 front ends.Clutch nut 9 can hold out against spacing ring 8 by outer catheter 4 front end screw threads, thereby spacing ring 8 holds out against again, clutch lever 7 is realized upper superimposed sheets 1 and lower superimposed sheets 2 is involutory.Like this, upper superimposed sheets 1 and lower superimposed sheets 2 are connected with outer catheter 4 to enter in vertebral body 11 by fixed guide fixed tube 6 and adjusting part.Clutch nut 9 is rotated backward, spacing ring 8 unclamps clutch lever 7, clutch lever 7 rotates 90 degree and retires backward, separates by the upper superimposed sheets 1 of the involutory rear interior rectangular channel realization of upper superimposed sheets 1 and lower superimposed sheets 2 thereby interior fixed bar 3 cross sections are rectangular with lower superimposed sheets 2.
Certainly, operation facility while considering actual use, fixed guide fixed tube 6 front ends are sharp tooth so that incision sclerotin plays fixation.Same, interior fixed bar 3 front end cross sections are rectangle, can realize better result of use.
In conjunction with actual service condition of the present invention, as shown in Figure 3, preoperative on vertebral body 11 side position x-ray images or CT profile, measurement vertebral body height b between soleplate Shang Xia 11, and foundation height b selects upper superimposed sheets 1 and the lower superimposed sheets 2 of appropriate size.Afterwards, by the upper superimposed sheets 1 assembling and lower superimposed sheets 2 successively pedicle enter in vertebral body 11, the continuous stack of superimposed sheets realizes vertebral body 11 completely and highly recovers.Because these superposing type full-height vertebral body 11 former support forces are firm, vertebral body 11 highly seldom declines, thereby can prevent highly too much loss assurance curative effect of postoperative vertebral body 11.
Can find out by above-mentioned character express, adopt after the present invention, rely on the enforcement that stack implanting portion assembly and apparatus parts can effectively coordinate spinal vertebral plasty, avoid occurring long-term postoperative vertebral height loss.And the present invention constructs rationally, easy and simple to handle, is convenient to promote the use of.
