Description
Technical field
This utility model relates to bone surgery instrument field, particularly a kind of bone cement directional injector.
Background technology
Under existing medical procedure, conventional bone cement infusion appliance is of a great variety, and also there is dissimilar defect in the bone cement infusion appliance that the different manufacturers that operation uses is produced, it is well known that the bone cement infusion appliance of routine is all made up of the parts such as sleeve and push rod, injected by manual operation in operation process, doctor carries out repeatedly to carry out x-ray bombardment to patient when bone cement injects in operation process, with determine the dosage of injecting and position whether correct, particularly inconvenient in the injection regulating bone cement different azimuth, once bone cement injects in certain orientation too much, leak out vertebral body, then can cause a series of complication, irremediable damage can be caused to patient, what operation process was become is very loaded down with trivial details, not only extend operating time, also add the risk of operation.
Therefore a kind of bone cement directional injector is needed.
Utility model content
In view of this, technical problem to be solved in the utility model is to provide a kind of bone cement directional injector.
The purpose of this utility model is achieved in that
A kind of bone cement directional injector that this utility model provides, comprises bone cement infusion appliance sleeve pipe and bone cement infusion appliance push rod;
Described bone cement infusion appliance cannula tip side is provided with the opening of discharging bone cement;
Described bone cement infusion appliance push rod is arranged in bone cement infusion appliance sleeve pipe;
Described bone cement infusion appliance push rod matches with bone cement infusion appliance sleeve pipe for injecting the bone cement in bone cement infusion appliance sleeve pipe;
The described bone cement infusion appliance sleeve pipe other end arranges the hands handle for rotating bone cement infusion appliance sleeve pipe; For realizing the directed injection bone cement from opening part to vertebral body by rotating bone cement infusion appliance sleeve pipe;
Described bone cement infusion appliance push rod is provided with the handle for promoting described bone cement infusion appliance push rod.
Further, described bone cement infusion appliance cannula tip is pyramidal structure.
Further, described bone cement infusion appliance sleeve pipe handle is provided with the labelling of instruction direction of angulations.
Further, the hatch bore diameter of described bone cement infusion appliance casing pipe front end is 3 millimeters to 6 millimeters.
Further, described opening is arranged at 10 millimeters to 15 millimeters, astragalus cement infusion appliance casing pipe front end.
Further, described opening is circular, square or one in ellipse.
Further, described opening is infundibulate, is positioned at the opening of the opening inside bone cement infusion appliance sleeve pipe slightly larger than outside.
This device has made larger improvement on the bone cement infusion appliance basis of routine, and object is the orientation of the injection vertebral body controlling bone cement, prevents bone cement from leaking out vertebral body, thus greatly reduces operating time, and improve surgical quality, what operation was become is simple to operation.Injected by manual operation in operation process, doctor carries out to carry out x-ray bombardment to patient when bone cement injects in operation process, to determine the dosage of injecting and position, by bone cement infusion appliance push rod, the lateral orifices of bone cement by bone cement sleeve pipe being released, realizing directed injection bone cement by rotating bone cement infusion appliance sleeve pipe.
