Description
Technical field
This utility model relates to field of medical technology, particularly relates to a kind of bone cement injection device.
Background technology
Bone cement in use, is injected bar release by bone cement by injecting bar by bone cement infusion appliance, and in push, bone cement can only be released by the end column injecting bar.Cause injection uneven like this, have a strong impact on injection effect, affect surgical outcome, and the common each addition of bone cement infusion appliance is certain, when bone cement injection rate is inadequate, needs to inject bar and take off filling bone cement, such troublesome poeration, uses inconvenience.Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of bone cement injection device.
This utility model is achieved through the following technical solutions:
A kind of bone cement injection device, comprise device body, the lower end of described device body is provided with injection bar, the round table-like structure that the lower end of described injection bar diametrically reduces gradually, and sidewall is provided with several small openings, the inside of described device body is provided with piston, air cavity is formed between described piston and device body top, described device body upper end is provided with the air bag communicated with air cavity, on the sidewall of described device body and the lower end being positioned at piston is provided with filler pipe, the upper end of described filler pipe is provided with filling cover.
As preferably, described piston is that quality of rubber materials is made.
As preferably, described filler pipe and device body one-body molded.
As preferably, described filling cover in horn-like structure, and with between filler pipe for being threaded.
Compared with prior art, the beneficial effects of the utility model are: this utility model structure is simple, reasonable in design, and this utility model by arranging small opening on the lower end sidewall injecting bar, and like this when bone cement injects, inject evenly, result of use is good; By arranging piston, air bag, the propelling movement process of bone cement can be realized like this, simple and convenient; Covering with filling by arranging filler pipe, continually as required can add bone cement like this in the process adding bone cement, easy to operate, save the time of operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. device body; 2. piston; 3. piston; 4. air bag; 5. filler pipe; 6. filling cover; 7. inject bar; 8. small opening.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
Refer to Fig. 1, a kind of bone cement injection device, comprise device body 1, the lower end of described device body 1 is provided with injects bar 7, the round table-like structure that the lower end of described injection bar 7 diametrically reduces gradually, and sidewall is provided with several small openings 8, like this when bone cement injects, inject evenly, result of use is good.
The inside of described device body 1 is provided with piston 2, and described piston 2 is made for quality of rubber materials.Form air cavity 3 between described piston 2 and device body 1 top, described device body 1 upper end is provided with the air bag 4 communicated with air cavity 3, during operation, extruding gasbag 4 pushes piston 3 downwards, and then bone cement is pushed injection bar 7, and the propelling movement process of bone cement can be realized like this, simple and convenient.On the sidewall of described device body 1 and the lower end being positioned at piston 2 is provided with filler pipe 5, described filler pipe 5 is one-body molded with device body 1, the upper end of described filler pipe 5 is provided with filling cover 6, described filling cover 6 is in horn-like structure, and with between filler pipe 5 for being threaded, sample continually as required can add bone cement in the process adding bone cement, easy to operate, has saved the time of operation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
