Abstract
The invention discloses a deformable cartilage polisher which comprises a hollow guide rod, wherein a handle for holding is arranged on the outer side of one end of the guide rod, and a polishing head made from elastic material is arranged at the other end; a steel core penetrates in the guide rod; and one end of the steel core is connected with the polishing head, and the other end penetrates out of the guide rod to be screwed with a nut. The invention aims to provide a polisher capable of entering the vertebral body through a narrow pedicle of the vertebral arch according to the defects of the prior art; after entering the vertebral body, the polisher deforms and expands to polish the vertebral body; and the polisher can prevent the sacculus from being punctured and also enables recruitment of the vertebral body through expansion deformation. The deformable cartilage polisher disclosed by the invention has a simple structure and is easy to operate.
Description
Technical field
The invention belongs to the bone surgery auxiliary appliance, particularly a kind of can be through get into the sander of vertebral body through narrow and small pedicle of vertebral arch.
Background technology
Pedicle vertebral body balloon dilatation is the Minimally Invasive Surgery of at present emerging treatment lumbar vertebra compression fracture, and a key step is a balloon expandable in the art, but bony spur usually punctures water-filling or inflating balloon in process of expansion.
Summary of the invention
The object of the invention provides a kind of sander of vertebral body that can get into through narrow and small pedicle of vertebral arch with regard to being to be directed against the defective of above-mentioned prior art, and getting into after strain expands, polishes, and can prevent that sacculus from puncturing, and have dilatancy, the function that vertebral body is opened again.
Its technical solution is following: deformable cartilage sander; The guide rod that comprises hollow; There is the handle of being convenient to grip in the one end outside of guide rod, and the other end is provided with the grinding head of being processed by elastomeric material, is equipped with steel core in the guide rod; One end of steel core connects grinding head, and the other end passes guide rod and nut screws togather.
Grinding head of the present invention is receiving steel core tractive front volume less, in use, can easily the end that grinding head is arranged be inserted vertebral body; After arriving the relevant position, swivel nut can be pulled outwardly steel core; The other end tractive grinding head of steel core, because grinding head receives stopping of guide rod end, grinding head is dilatancy under the extruding of steel core and guide rod end; Grinding head after the dilatancy can carry out sanding operation, also vertebral body is answered simultaneously and opens.
Therefore grinding head of the present invention adopts elastomeric material to make, the drawback of having avoided sacculus in the past to puncture easily.Have simple in structure, the characteristics of easy operating.
Below in conjunction with accompanying drawing the present invention is further specified.
Description of drawings
Fig. 1 is a structural representation of the present invention (grinding head is at quiescent condition).
Fig. 2 is the structural representation of grinding head of the present invention when swelling state.
The specific embodiment
As shown in Figure 1, the present invention includes the guide rod 1 that comprises hollow, there is the handle of being convenient to grip 2 in the end outside of guide rod 1; The other end is provided with the grinding head of being processed by elastomeric material 3; Be equipped with steel core 4 in the guide rod 1, an end of steel core 4 connects grinding head 3, and the other end passes guide rod 1 and screws togather with nut 5.
Above-mentioned grinding head 1 can adopt rubber, silica gel etc. to have elasticity and attrition resistant material.
Below only be to indicative explaination of the present invention, the present invention includes but be not limited only to above embodiment that its associated components also can have other conspicuous variations.
