Description
Technical field
This utility model relates to medical internal fixation device technical field, relates in particular to dynamic stabilization system device between a kind of spinous process.
Background technology
At present, interspinal non-rigid stabilization system device can be treated effectively because the low back pain that Lumbar Intervertebral Disc Degeneration causes and root pain, can unload the pressure that causes little joint of losing owing to disc height, recover disc height, keep the movable property of vertebral body, the integrity of anatomical structure, keep the stability of sections simultaneously.But in operation, the structure of interspinal non-rigid held stationary system is bigger in the prior art, cause that the operation wound face is relatively large in operation implant into body process, and difficult the implantation between spinous process is treated.
The utility model content
In view of this, the purpose of this utility model is to overcome deficiency of the prior art, and dynamic stabilization system device between Wicresoft's spinous process that a kind of relative structure is little, convenience is implanted the dismounting capable of being combined for the treatment of between spinous process is provided.
The technical solution of the utility model provides dynamic stabilization system device between a kind of spinous process, it comprises the stabilization system device main part, the two ends of described stabilization system device main part are connected with the flank section of passing for bandage respectively, and described flank section detachably is combined on the described stabilization system device main part.
Preferably, described stabilization system device main part is provided with projection with the two ends that described flank section is connected, and correspondingly the position that is complementary of the projection of described flank section and described stabilization system device main part is provided with endoporus.
Preferably, described projection is the external splines of cylindricality, and correspondingly described endoporus is the internal spline of cylindricality.
Preferably, described flank section is provided with the bandage perforation of passing for described bandage.
Preferably, two described flank section are arranged on the both sides of described stabilization system device main part symmetrically.
Preferably, described stabilization system device main part is provided with the main part through hole.
Adopt technique scheme to have following beneficial effect: connect two flank section by the two ends at the stabilization system device main part, this flank section can detachably be combined on the stabilising arrangement main part.About the stabilization system device main part, locate, the flank section that is used for passing bandage be designed to detachably, the structure of the left and right sides, ground capable of being combined both wings formula, it not only makes the operation formula more convenient, more flexible, and reached under the less situation of wound face and just can finish operation, interspinal ligaments can remain to more than 50%, reduce wound, keep the bodily fuctions to greatest extent.
Description of drawings

The axonometric chart of dynamic stabilization system device between a kind of spinous process that Fig. 2 provides for this utility model.
The Reference numeral synopsis:
1-stabilization system device main part; 2-flank section; 3-projection; 4-endoporus;
The perforation of 5-bandage; 6-main part through hole.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-2, dynamic stabilization system device between a kind of spinous process that this utility model provides, it comprises stabilization system device main part 1, the two ends of this stabilization system device main part 1 are connected with the flank section 2 of passing for bandage respectively, and this flank section 2 can detachably be combined on the stabilization system device main part 1.Dynamic stabilization system device between a kind of spinous process that this utility model provides, by the member that will originally be integrated, split into stabilization system device main part 1 and two flank section 2, and these two flank section 2 can be combined on the stabilization system device main part 1 with splitting, particularly, these two flank section 2 can be combined to the both sides of stabilization system device main part 1 as required, also can split from the both sides of stabilization system device main part 1.It can independent assortment, convenient, flexible, in operation process, can on smaller wound face, just can implant stabilization system device main part 1, and then according to operative space, select suitable angle, about two flank section 2 be fixed on the stabilization system device main part 1, by bandage dynamic stabilization system device between spinous process is fixed on the spinous process again and treats, it not only makes the operation formula more convenient, more flexible, and reached under the less situation of wound face and just can finish operation, reach the effect of minimally-invasive treatment.
Preferably, the two ends that aforementioned stable system and device main part 1 is connected with flank section 2 are provided with projection 3, and correspondingly the position that is complementary of the projection 3 of above-mentioned flank section 2 and stabilization system device main part 1 is provided with endoporus 4.Be position that flank section 2 is connected with stabilization system device main part 1 be provided with for the projection 3 corresponding endoporus that cooperate 4.This projection 3 preferably is the external splines of cylindricality, and correspondingly endoporus 4 is the internal spline of cylindricality.
Preferably, flank section 2 is provided with the bandage perforation 5 of passing for the bandage (not shown).Bandage passes bandage perforation 5, and said apparatus is fixed on the spinous process to be treated.
Preferably, two flank section 2 are arranged on the both sides of stabilization system device main part 1 symmetrically.Two flank section 2 are arranged on the both sides of stabilization system device main part 1 symmetrically, and integrated positioning during convenient operation also makes things convenient for bandage that it is bound.
Preferably, stabilization system device main part 1 is provided with main part through hole 6.By main part through hole 6 is set, to reach the purpose of elastic dynamic design, alleviate intercalated disc pressure, keep fine motion, increase the stimulation to the pathological changes intercalated disc, promote the intervertebral disc restore funcitons of pathological changes.
In use, at first stabilization system device main part 1 is implanted between the lumbar vertebra sections that needs treatment, again according to operative space, select suitable angle, respectively about the endoporus 4 of two flank section 2 projection 3 of aiming at stabilization system device main parts 1 both sides, sequentially two flank section 2 removably are combined to the both sides of stabilization system device main part 1, by the bandage that passes bandage perforation 5 on the flank section 2 dynamic stabilization system device between spinous process is fixed on the spinous process then and treats, it not only makes the operation formula more convenient, more flexible, and reached under the less situation of wound face and just can finish operation, reach the effect of minimally-invasive treatment.Its material is elected polyether-ether-ketone (PEEK) as, the elastic modelling quantity of PEEK more mates with the vertebral body rear structure, so that the vibration energy when alleviating the load that vertebral body bears and absorbing motion, it can better be treated with II, III, IV degree pathological changes, the lumbago disease that simple lumbar vertebra segmental unstability causes.
Above-described only is principle of the present utility model and preferred embodiment.Should be pointed out that for the person of ordinary skill of the art, on the basis of this utility model principle, can also make some other modification, also should be considered as protection domain of the present utility model.
