The specific embodiment
Superposing type full-height vertebral body 11 formers shown in Fig. 1～3, include stack and implant parts, described stack is implanted on the parts and is connected with the apparatus parts, and its unusual part is: the stack that this utility model adopts is implanted parts and is included the superimposed sheets assembly.Simultaneously, the apparatus parts includes interior fixed bar 3, is connected with interior fixed bar 3 at the superimposed sheets assembly.Specifically, interior fixed bar 3 outer setting have outer catheter 4, are provided with at outer catheter 4 leading portions and control assembly 5, control assembly 5 and contact with the superimposed sheets assembly.And periphery, outer catheter 4 stage casing is provided with fixed guide fixed tube 6, is connected with adjusting part on the fixed guide fixed tube 6, is 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 the better embodiment of this utility model one, for the ease of using, the superimposed sheets assembly includes superimposed sheets 1 and lower superimposed sheets 2, is provided with groove in upper superimposed sheets 1 and lower superimposed sheets 2.Thus, when upper superimposed sheets 1 and lower superimposed sheets 2 involutory assembling, groove is merged into connecting groove.Correspondence is with it, holds and is provided with adapter 10 on the assembly, and 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 at 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.Simultaneously, be connected with clutch lever 7 at spacing ring 8.Certainly, for the 9 more effective work of clutch nut, be provided with screw thread at outer catheter 4 leading portions.Like this, when practical operation, clamp nut 15 can realize that handle 14 links to each other 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 the upper superimposed sheets 1 of clutch lever 7 realizations again and lower superimposed sheets 2 is involutory.Like this, upper superimposed sheets 1 and lower superimposed sheets 2 are connected with outer catheter 4 in order to enter in the vertebral body 11 by fixed guide fixed tube 6 and adjusting part.With clutch nut 9 backward rotation, spacing ring 8 unclamps clutch lever 7, clutch lever 7 rotates 90 degree and retires backward, realizes that by upper superimposed sheets 1 and lower superimposed sheets 2 involutory rear interior rectangular channels upward superimposed sheets 1 is separated with lower superimposed sheets 2 thereby interior fixed bar 3 cross sections are rectangular.
Certainly, operation facility when considering actual use, fixed guide fixed tube 6 front ends are sharp tooth so that the 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 operating position of the present utility model, as shown in Figure 3, art is front on vertebral body 11 side position x-ray images or CT profile, measurement vertebral body height b between soleplate about in the of 11, and foundation height b selects upper superimposed sheets 1 and the lower superimposed sheets 2 of appropriate size.Afterwards, with the upper superimposed sheets 1 that assembles and lower superimposed sheets 2 one by one pedicle enter in the vertebral body 11, the continuous stack of superimposed sheets realizes that fully vertebral body 11 highly recovers.Because these superposing type full-height vertebral body 11 former support forces are firm, vertebral body 11 highly seldom descends, thereby can prevent that postoperative vertebral body 11 from highly too much losing the assurance curative effect.
Can find out by above-mentioned character express, adopt this utility model after, relying on stack and implanting the enforcement that parts and apparatus parts can effectively cooperate the spinal vertebral plasty, avoid occurring the long-term postoperative vertebral height and lose.And this utility model structure rationally, and is easy and simple to handle, is convenient to promote the use of.
