Abstract
The utility model discloses a bone cement injection device. The bone cement injection device comprises a filler pipe and a push rod; the push rod is inserted into one end of the filler pipe; an injection hole is formed in the end face of the other end of a filler; at least one side slot communicated with an inner cavity of the filler pipe is formed in a pipe arm at the other end of the filler pipe. According to the bone cement injection device, the injection area is increased by forming the side slot in the filler pipe, so that the time of the bone cement infiltrating into a suture is shortened, and bone cement infiltrates more fully; therefore the incidence of leakage of the bone cement is greatly reduced.
Description
Technical field
This utility model relates to armarium, is specifically related to a kind of bone cement injection device.
Background technology
Along with aged tendency of population, osteoporosis has become a kind of common disease of serious harm senior health and fitness, fractures for the main severe complication of this disease, and its incidence rate is 5.36%.Only just there is osteoporosis patient more than 2,800 ten thousand in the U.S., annual new 1,500,000 osteoporotic fractures, and the medical expense causing because of fracture every year reaches 15,000,000,000 dollars, estimates that the year two thousand thirty will reach 60,000,000,000 dollars.Wherein, the most common with compression fracture of vertabral body.In China, within 2002, statistics has sufferers of osteoporosis face nearly 8,200,000, and 7%, the 50 years old above city elderly woman vertebral fracture incidence rate that accounts for total population is 15%.The violent lumbago and backache of the normal generation of these patients, disability is self care ability even, makes quality of life degradation.The treatment means of conventional bone sponginess fracture comprise lie up, oral analgesic, calcium preparation etc., part Principle of Pain symptom can be eased, but, more than at least 30% patient needs hospitalization because above-mentioned treatment is difficult to prove effective, surgical operation is because wound is large, complication is difficult to extensive use more.Therefore, alleviating pain, interrupts vicious cycle rapidly, recovers vertebral height, and correcting as far as possible kyphosis deformity becomes the key for the treatment of Osteoporotic Vertebral Compression Fractures.
In recent years, minimally invasive surgery development is swift and violent, and new technique, new method, new equipment, new concept continue to bring out.As the new technique of minimally invasive spine surgical field, vertebroplasty has been subject to people's extensive concern.Percutaneous vertebroplasty (percutaneous vertebroplasty, PVP) protruding plasty (percutaneous kyphoplasty, PKP) is a new spinal surgery less invasive techniques for the treatment of in recent years osteoporotic vertebral fracture and after balloon angioplasty.
But the seepage of bone cement can limit the application of this new shape minimally invasive spinal surgery technology.Because the seepage of bone cement is to cause the immediate cause of the severe complications such as spinal compression, nerve injury and pulmonary infarction.The injection device using at present carries out bone cement injection.Due to the injection port diameter less (being generally 1mm left and right) of these injection devices, simultaneously, bone cement has poor fluidity, setting time is short, be difficult for infiltering the medium feature of fine sutura, therefore in the time using these injection device injection bone cements, easily produce seepage, thereby improved the difficulty of operation.While using these injection device injection bone cements, also can cause operating time long, increase doctor and patient's burden.
Utility model content
The purpose of this utility model is the deficiency existing in order to overcome above prior art, provides a kind of simple and reasonable for structure, can reduce bone cement seepage and can complete fast the bone cement injection device of operation.
The purpose of this utility model realizes by following technical scheme: this bone cement injection device, comprise and insert organ pipe and push rod, one end of organ pipe is inserted in the insertion of described push rod, the end face of the described other end of inserting organ pipe is provided with injection orifice, described in insert the other end of organ pipe pipe arm be provided with at least 1 side channel communicating with the inner chamber of inserting organ pipe.
Described side channel is straight shape groove, and described straight shape groove and the central axes of inserting organ pipe, and described straight shape groove distributes with respect to the central shaft even circumferential of inserting organ pipe.Concrete, straight shape groove processing is simple and convenient, is uniformly distributed that can to ensure to make bone cement to infiltrate more abundant simultaneously, thereby further reduces the incidence rate of bone cement seepage.
The groove width of described straight shape groove is 0.4mm～0.6mm, and the length of described straight shape groove is 10mm～20mm.
Described side channel is arcuate groove, and described arcuate groove is parallel with the end face of the other end, and described arcuate groove distributes with respect to the central shaft even circumferential of inserting organ pipe.Concrete, arcuate groove is uniformly distributed, and it is more abundant that this can ensure to make bone cement to infiltrate, thereby further reduce the incidence rate of bone cement seepage.
Concrete, the groove width of described arcuate groove is 0.4-0.6mm, the circular arc angle of described arcuate groove is 90 °.
Preferred as one, the quantity of described side channel is 3 or 4.
For convenience of clinical manipulation, described in insert organ pipe one end be provided with flange, the flange connecting with insert organ pipe and be T shape.In the time carrying out clinical injection, utilize the forefinger of a hands and middle finger to catch on flange, female finger pressure of the same hand push rod, and sharp push rod inserts and inserts organ pipe, infiltrates sutura thereby bone cement flows out in inserting organ pipe.
For convenience of clinical manipulation, the other end of described push rod is provided with and pushes away handle, connect push away handle and push rod is T shape.
This utility model has advantages of as follows with respect to prior art: this bone cement injection device is by being provided with side channel inserting organ pipe, increase injection area, this has shortened the time of bone cement infiltration sutura, and infiltration is more abundant, thereby greatly reduces the incidence rate of bone cement generation seepage.This bone cement injection device infiltrates the time of sutura owing to having shortened bone cement, thereby has simplified clinical manipulation, therefore reduced the difficulty of operation, has reduced doctor and patient's burden.It is more abundant that this bone cement injection device can allow bone cement infiltrate, and ensured the success rate of operation, shortens patient's rehabilitation duration.
Brief description of the drawings
Fig. 1 is the structural representation of the bone cement injection device of embodiment 1.
Fig. 2 is the structural representation of the bone cement injection device of embodiment 2.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1
