Abstract
The utility model discloses a solidifiable material injection device with a side hole. The solidifiable material injection device comprises an injection needle head, wherein one end of the injection needle head has a smooth closed structure; and a material outlet is formed on the side wall of the injection needle head with the smooth closed structure. The material outlet is formed on the side wall of the front section of the injection needle head, and the smooth closed structure is formed at the end of the injection needle head; during use, bone cement (or a solidifiable bone material) is injected from the material outlet on the side wall of the injection needle head and compactly combined with spongy bone so as to be prevented from penetrating into the blood; the spongy bone density is effectively increased, and complication is prevented; high safety of operation is guaranteed; and the operation quality is improved. The solidifiable material injection device is rational and simple in structure, low in cost, good in using effect and large in application range and deserves to popularization.
Description
Technical field
This utility model relates to a kind of orthopedic medical device, especially a kind of band side opening curable materials injection device.
Background technology
Fracture is meant seriality and the partially or completely destructive a kind of disease of integrity quilt that causes bone owing to reasons such as wound or pathology.The fractures key step have reset, fix, functional exercise etc.Because human body sclerotin individual variation is bigger, the fixed effect of conventional fixators tool also has than big-difference.Particularly for osteoporotic patient; Because bone trabecula attenuation in the spongy bone, sparse even disappearance, in the internal fixation operation treatment, staple is not enough to local constant intensity; Need to fill bone cement (or curable bone-grafting material) to strengthen bone density, be convenient to staple and fix.Bone cement (or curable bone-grafting material) injection at present mainly is to inject through traditional syringes, and bone cement (or curable bone-grafting material) often can not contact with sclerotin fully effectively, and it is loosening to be prone to generation after solidifying, and fixed effect is still relatively poor.Particularly near end of thighbone is fixing,,, bone cement can cause cardiac arrest even sudden death when penetrating in the blood vessel because the injection needle tip fluid of conventional syringe when injecting bone cement (or curable bone-grafting material), is injected in the hip joint easily.Also do not inject at present better, the safe and reliable curable materials injection device of fixed effect.
Summary of the invention
This utility model will solve the shortcoming of above-mentioned prior art, and a kind of better, safe and reliable band side opening curable materials injection device of fixed effect that injects is provided, and satisfies clinical osseous surgery treatment demand.
This utility model solves the technical scheme that its technical problem adopts: this band side opening curable materials injection device, comprise the injection syringe needle, and inject syringe needle one end and be smooth enclosed construction setting, have discharging opening on the injection syringe needle sidewall of this smooth enclosed construction end.Like this; Be smooth enclosed construction setting owing to inject the syringe needle end, when injecting syringe needle insertion passage, wear femoral head even insert; The smooth enclosed construction that injects the syringe needle end can will be inserted and wear the position and seal; Bone cement (or curable bone-grafting material) is difficult for annotating in the hip joint, prevents that effectively bone cement etc. from penetrating in the blood, effectively prevents the appearance of complication; When injecting bone cement (or curable bone-grafting material), evenly rotate whole injection device simultaneously; Variation has just taken place in the discharging opening position, and bone cement is fully infiltrated through in the spongy bone, effectively improves the density of fixed position; Thereby improve the success rate of fixing operation, help patient's rehabilitation.
Further, band side opening curable materials injection device also comprises syringe body, injects the syringe needle liquid feeding end and is connected with syringe body.Being convenient to control bone cement (or curable bone-grafting material) like this injects.The discharging opening width is at 2 ㎜～30 ㎜.Like this, the operation that is suitable for different sizes is used.Inject syringe needle and be titanium or titanium alloy structure setting.Titanium or titanium alloy structure and human body do not have rejection, use more safe and reliable.Syringe body is arranged with outward controls frame.Help the doctor to control injection device like this, be convenient to control, guarantee to perform the operation and to carry out safely.
The effect that this utility model is useful is: this utility model rational in infrastructure, simple through offering discharging opening injecting on the syringe needle leading portion sidewall, and is provided with the smooth seal structure injecting the syringe needle end; Bone cement during use (or curable bone-grafting material) outpours with spongy bone from the discharging opening on the injection syringe needle sidewall and combines closely; Can prevent that bone cement etc. from penetrating in the blood, effectively improve bone density, prevent that complication from taking place; Guarantee high operation safety, improve the operation quality.This utility model cost is reasonable, and result of use is good, and the scope of application is big, is worthy to be popularized.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Description of reference numerals: syringe body 1, inject syringe needle 2, smooth enclosed construction 3, discharging opening 4 is controlled frame 5.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further:
With reference to accompanying drawing: this band side opening curable materials injection device in the present embodiment; Comprise syringe body 1, inject syringe needle 2; Injecting syringe needle 2 one ends is connected with syringe body 1; The other end is smooth enclosed construction 3 and is provided with, and has discharging opening 4 on injection syringe needle 2 sidewalls of these smooth enclosed construction 3 ends.Discharging opening 4 width are at 2 ㎜～30 ㎜.Inject syringe needle 2 and be titanium or titanium alloy structure setting.Syringe body 1 outer being arranged with controlled frame 5.
The diameter of the injection syringe needle 2 in this utility model and the diameter of bone property passage are complementary, and are convenient to the better and bony fusion of bone cement (or curable bone-grafting material).Injection syringe needle in this utility model not only can adopt titanium, titanium alloy to process, and can also process with the material that plastifying material of rustless steel or stability and safety etc. does not repel.When this utility model uses, set up bone property passage, the curable bone-grafting material that allotment is good is contained in the syringe body; To inject syringe needle and aim at the insertion of bone property passage, the control syringe body carries out pusher, gently changes whole injection device in the process of injecting curable bone-grafting material; And progressively withdraw from bone property passage; Guarantee that curable bone-grafting material fully combines with sclerotin, improve surgical effect, help patient's rehabilitation.
Though this utility model is through illustrating and describe with reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
