Abstract
The utility model relates to an orthopaedics intraspinal implant, in particularly an ivnterspinal strutting device which has a strutting main body and a movable separation blade, a big end of the strutting main body has a strutting separation blade, a small end of the strutting main body has a screw hole, the movable separation blade middle part has a pylome and a bolt in the pylome, the movable separation blade connects with the strutting main body by inserting the bolt into a screw hole, the strutting main body outside circle between the separation blade and the movable separation blade contacts with the upper interspinal and the down interspinal. The interspinal strutting device has simple structure and is convenient to operate for saving operation time; the strutting main body and the movable separation blade insert lumbar from both side without shearing ligament; and the interspinal strutting device can adjust width of the movable separation blade and the strutting separation blade according with patient condition.
Description
Technical field
This utility model relates to orthopaedics spinal column implant, device for spreading between especially a kind of spinous process.
Background technology
The vertebral disease sickness rate is higher at present, has a strong impact on people's life health.Main cause is because lumbar intervertebral disc protrusion becomes atrophy, makes that the gap dwindles between the vertebra awl, and the joint is also relative with interarticular gap between awl dwindles, and is urged to spinal cord and nerve roots, produces due to paralysis or the pain.The modus operandi of this disease of general therapeutic is to implant pedicle screw to draw back gap between awl, and its fusion rate is higher, but but still has some problems.The operation trouble, after the operation, the patient still complains the symptom that rachiagia is arranged, in addition As time goes on, and momental increase, the regression of adjacent segment more easily takes place.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problems of the technologies described above, this utility model provides device for spreading between a kind of spinous process, and it is simple in structure, and operation technique is convenient.
The technical scheme that its technical problem that solves this utility model adopts is: device for spreading between a kind of spinous process, have the main body of strutting and active blade, strut the big end of main body and have the catch of strutting, small end has screwed hole, the active blade middle part has a through hole and is through the interior bolt of through hole, active blade inserts in the screwed hole and struts main body and link to each other by bolt, struts and struts main body periphery contact upper aristate process and following spinous process between catch and the active blade.
Described through hole is an elongated hole, and bolt slidably is through in the elongated hole.
The beneficial effects of the utility model are: this device for spreading spinous process is simple in structure, and is easy to operate, saves the operating time; Strut main body, active blade inserts lumbar vertebra from both sides, need not cut off ligament; And can regulate active blade and the width that struts catch according to patient's situation.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation that struts main body.
Fig. 3 is the structural representation of active blade.
Fig. 4 is that this uses novel assembling process sketch map.
Among the figure: 1. strut main body, 11. strut catch, 12. screwed holes, 2. active blade, 21. through holes, 22. bolts.
The specific embodiment
Shown in Fig. 1～4, device for spreading between a kind of spinous process, have main body of strutting 1 and active blade 2, strut main body 1 big end and have the catch of strutting 11, small end has screwed hole 12, active blade (2) middle part has a through hole 21 and is through bolt 22 in the through hole 21, and active blade 2 inserts in the screwed holes 12 and struts main body 1 and link to each other by bolt 22, struts and struts main body 1 periphery contact upper aristate process and following spinous process between catch 11 and the active blade 2.
The small end that struts main body 1 inserts from the upper aristate process and the one side in following spinous process space earlier, pass the another side in upper aristate process and following spinous process space, bolt 22 with active blade 2 inserts in the screwed hole 21 then, make that to strut main body 1 fixing with active blade 2, active blade 2 and strut the both sides that catch 11 withstands on upper and lower spinous process respectively.Through hole 21 is an elongated hole, and bolt 22 slidably is through in the elongated hole, according to patient's situation by slide bolt 22 adjustable catch 2 and the width that struts catch 11.
Claims (2)
1. device for spreading between a spinous process, it is characterized in that: have main body of strutting (1) and active blade (2), strut the big end of main body (1) and have the catch of strutting (11), small end has screwed hole (12), active blade (2) middle part has a through hole (21) and is through the interior bolt (22) of through hole (21), active blade (2) inserts in the screwed hole (12) and struts main body (1) and link to each other by bolt (22), struts to strut main body (1) periphery between catch (11) and the active blade (2) and contact upper aristate process and following spinous process.
2. a kind of device for spreading spinous process according to claim 1 is characterized in that: described through hole (21) is an elongated hole, and bolt (22) slidably is through in the elongated hole.
