Detailed description of the invention
With reference to Fig. 1 ~ Fig. 4, the present invention is a kind of bone cement pusher, comprise Cement fixation sleeve pipe 1 and one end penetrates the Cement fixation push rod 2 carrying out bone cement propelling in Cement fixation sleeve pipe 1, the tail end of Cement fixation sleeve pipe 1 is provided with lever 11, the tail end of Cement fixation push rod 2 is provided with and pushes away handle 21, communicate with Cement fixation sleeve pipe 1 and be provided with female Luer 12, the front end of Cement fixation sleeve pipe 1 is closed, and the front end around Cement fixation sleeve pipe 1 is provided with some bone cement extrusion cavities 13.
This bone cement pusher is after stretching to diseased region by the top of Cement fixation sleeve pipe 1, advance by Cement fixation push rod 2, the bone cement in Cement fixation sleeve pipe 1 is forced evenly to be extruded by the bone cement extrusion cavities 13 one-tenth 360 degs around Cement fixation sleeve pipe 1, or extrude according to clinical needs orientation, can make diseased region pressurized evenly and reduce, thus effectively improving surgical effect.
As the preferred embodiment of the present invention, lever 11 is provided with hollow hole, and Cement fixation sleeve pipe 1 is fixedly connected with by hollow hole, and Cement fixation push rod 2 penetrates in Cement fixation sleeve pipe 1 by hollow hole, and female Luer 12 is arranged on hollow hole position.
As the preferred embodiment of the present invention, each bone cement extrusion cavities 13 is between 0 ~ 3 centimetre of Cement fixation sleeve pipe 1 front portion.As the preferred embodiment of the present invention, bone cement extrusion cavities 13 is evenly arranged around the outer wall of Cement fixation sleeve pipe 1.
As the preferred embodiment of the present invention, bone cement extrusion cavities 13 is evenly arranged on the outer wall of Cement fixation sleeve pipe 1 side.
Bone cement extrusion cavities 13 can in the outer unidirectional or oriented arrangement of Cement fixation sleeve pipe 1, to determine the propelling movement position of bone cement more accurately.
As the preferred embodiment of the present invention, each bone cement extrusion cavities 13 is circular hole or elliptical aperture.
As the preferred embodiment of the present invention, the hole wall of each bone cement extrusion cavities 13 periphery is to pushing away handle 21 and the inclination of lever 11 place end, and the gradient of bone cement extrusion cavities 13 periphery hole wall is 0 ~ 30 degree.When injecting bone cement, the Cement fixation sleeve pipe 1 of Cement fixation device is extend in service aisle, each bone cement extrusion cavities 13 of Cement fixation sleeve pipe 1 enters in the vertebral body cavity subsided that realizes propping up, then jacketed syringe is used to be expelled in the passage in Cement fixation sleeve pipe 1 by the bone cement modulated by female Luer 12, promote bone cement in the passage again Cement fixation push rod 2 being inserted Cement fixation sleeve pipe 1, Cement fixation is arrived in vertebral body cavity.
While injecting bone cement, Cement fixation sleeve pipe 1 can be rotated by circumference, make bone cement be full of whole cavity, then Cement fixation sleeve pipe 1 is shifted out from service aisle, finally service aisle is shifted out external.Use the Cement fixation device of said structure, in Cement fixation process, pathological changes vertebral body substantially can not larger injection pressure, thus can not increase the weight of the degree of fracture of pathological changes vertebral body, and bone cement dispersed filler makes Cement fixation more even, and surgical effect is better.
In this bone cement pusher, also each bone cement extrusion cavities 13 is processed, the hole wall of each bone cement extrusion cavities 13 is made to do process, the emission direction of bone cement can be changed, the rightabout that the incline direction of hole wall is pushed in Cement fixation sleeve pipe 1 towards bone cement sprays, the pressure of bone cement to diseased region can be reduced further, and do not affect the propelling movement amount of bone cement.
In addition, in this bone cement pusher, the top of Cement fixation sleeve pipe 1 can adopt round and smooth top or rectangle top to arrange, and round tip is arranged can be avoided producing injury to diseased region.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent modification or replacement are all included in the application's claim limited range.
