Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.Following example are only for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
A kind of bone filling gun of the present utility model, including injection tube, described injection tube is made up of the first cylinder 1 and the second cylinder 2, it is connected with entry needle 3, sleeve pipe 4, piston 5 and spring 6 in turn between described first cylinder 1 and the second cylinder 2, described piston 5 is positioned at the second cylinder 2, its outer sheathed described spring 6；Described sleeve pipe 4 is positioned at the first cylinder 1, and its one end has most advanced and sophisticated 41, and the other end is connected with described piston 5, and described sleeve pipe 4 is inserted in entry needle 3, and entry needle 3 is stretched out at its tip 41.
Described first cylinder 1 is connected by a safety loop 7 with the second cylinder 2, and described safety loop 7 is set in the outside of the second cylinder 2, and both sides are provided with sphenoid 71.In use, owing to the second cylinder 2 being exerted a force, the sphenoid 71 of safety loop 7 can provide good support.
Being socketed with spiral cover 8 outside second cylinder 2, when having spiral cover 8, safety loop 7 is set in the outside of spiral cover 8, and spiral cover 8 is provided with safety lock 9, and described safety lock 9 extends radially through described spiral cover 8, and against described second cylinder.In use, it is necessary to extracting safety lock 9 could exert a force to the second cylinder 2, it is prevented that maloperation.
Described piston 5 is made up of the body of rod 51, springlock 52, packing ring 53 and connector 54, and described springlock 52 is socketed on the body of rod 51, and connector 54 is connected with the body of rod 51 and is positioned at springlock 52, and packing ring 53 is set in outside described springlock 52.
Described first cylinder 1 is also associated with jam nut 10.Can the insertion depth of adjusting sleeve pipe 4 by jam nut 10.
Bone filling gun of the present utility model in use, promotes the second cylinder 2, under the effect of piston 5, entry needle 3 and sleeve pipe 4 remove from the first cylinder 1, owing to sleeve pipe 4 has most advanced and sophisticated 41, therefore conveniently penetrate people's bone, simultaneously, entry needle 3 is brought into, after penetrating, second cylinder the 2, first cylinder 1 and sleeve pipe 4 are removed, only surplus entry needle 3, now, medicine can be injected into by entry needle 3.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model know-why; can also making some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
