Description
Technical field
The utility model is related to medical instruments field, more particularly to a kind of elbow bone cement pusher.
Background technology
PVP refer to percutaneously by injection bone cement in the export-oriented centrum of pedicle of vertebral arch or pedicle of vertebral arch with reach increase centrum intensity and
Stability, prevent from collapsing, pain of alleviation, a kind of or even part minimally invasive spinal surgery technology for the purpose of recovering vertebral height.It is main
The treatment of compression fracture of vertabral body is applied to, compression fracture of vertabral body is the most common complication of sufferers of osteoporosis face, can be made
Into local pain, moving obstacle, serious also results in lower limb paralysis.
Cement fixation device is one of apparatus in percutaneous vertebroplasty surgery systems, is mainly used in Cement fixation extremely
Inside disease damage centrum, the structure of Cement fixation device in the market is single, and bone cement injection outlet is all disposed within bone cement
The most head end of sleeve pipe, and it is straight peen.Therefore, in order that Cement fixation is more uniform symmetrical in clinic, usual use is worn
Thorn approach punctures for bilateral.
The deficiency that the Cement fixation device of said structure form is present has at following 2 points：1. bone cement is in filling due to side
It to single, can only forward inject, cause filling uneven, do not reach expected surgical effect；2. punctured using bilateral to patient
Injury is big, and operating time length, high cost.
Utility model content
The purpose of this utility model is to provide a kind of elbow bone cement that bone cement can be made uniformly, to be symmetrically filled into centrum
Pusher.
Technical solution adopted in the utility model is：
A kind of elbow bone cement pusher, including filling sleeve pipe and filling push rod, filling sleeve pipe include sleeve pipe handle and straight
Pipe, straight pipe one end connection sleeve pipe handle, the straight pipe other end sets flexible elbow, and filling push rod includes pusher grip
With the bar core in the straight pipe of insertion, pusher grip connecting rod core, the side of elbow has some injection outlets.
The improvement of technical solutions of the utility model is further used as, elbow uses memory alloy material.
The improvement of technical solutions of the utility model is further used as, injection outlet is arranged on half of side or whole of elbow
On individual side, injection outlet distribution density is 1~5/cm2。
The improvement of technical solutions of the utility model is further used as, female Luer, Shandong are provided with the tail end for filling handle
You connect joint with the inner chamber of pipe.
The improvement of technical solutions of the utility model is further used as, the front end of elbow is enclosed tip or round end.
The improvement of technical solutions of the utility model is further used as, the length of elbow is 10~40mm, point of injection outlet
Cloth region is in the interval of 0~24mm of front end apart from elbow.
The improvement of technical solutions of the utility model is further used as, the pore size of injection outlet is 0.2~2mm.
Be further used as the improvement of technical solutions of the utility model, the bending angle between elbow and straight pipe be 30 °~
90°。
The beneficial effects of the utility model：The elbow of this elbow bone cement pusher inserts centrum through service aisle, curved
Head recovers advance bending from straight form, when injecting bone cement in the cavity from elbow, is made by rotation, telescopic tube handle
Outlet port must be injected constantly to change, the bone cement for extruding injection by bar core symmetrically, can be sprayed into equably in centrum, greatly
The procedure efficiency and effect improved greatly.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the structure chart of the utility model embodiment；
Fig. 2 is the implementation figure of the utility model embodiment.
Embodiment
Referring to Figures 1 and 2, the utility model is a kind of elbow bone cement pusher, including fills sleeve pipe and fill push rod,
Fill sleeve pipe include sleeve pipe handle 1 and rigid straight pipe 2, the straight one end connection sleeve pipe handle 1 of pipe 2, the other end is provided with soft
The elbow 3 of property；Filling push rod includes pusher grip 4 and the bar core 5 inserted in straight pipe 2, and bar core 5 is formed closely with straight pipe 2
Laminating, the pusher grip 4 is connected to bar core 5.The side of elbow 3 has some injection outlets 6.
Elbow 3 uses metal material（Stainless steel, Nitinol etc.）Or high molecule plastic（PEEK、PU、PTFE、Nylon
Deng）Or composite, i.e. memory alloy material, straight pipe 2 and bar core 5 can also use the material consistent with elbow 3.
The bending place of elbow 3 and straight pipe 2 directly can be shaped using high temperature or machinery, can also first cut off bending place
Using high temperature or machinery sizing after portion of material.Further, the bending place equably covers one layer and is used to improve material thing
The macromolecular material of rationality energy.
Material inserts centrum 8 for the elbow 3 of memorial alloy through service aisle 9, and elbow 3 is first straight form, from work
After making passage 9 out, elbow 3 recovers advance bending in centrum 8；When injecting bone cement from the cavity of elbow 3, pass through
Rotation, telescopic tube handle 1 make it that the position of injection outlet 6 constantly changes, and the bone cement for extruding injection by bar core 5 can
Symmetrically, equably spray into centrum 8, the procedure efficiency and effect greatly improved, reduce the puncture time of pusher, alleviate pair
