Description
Technical field
The utility model relates to a kind of bone cements to inject guide device, and in particular to a kind of bone is strengthened operation and infused with bone cement
Enter guide device, suitable for treating vertebral fracture, tumor of spine and the bone tumour or defect at other positions；Belong to medical instrument skill
Art field.
Background technique
Aging has been increasingly becoming a problem of puzzlement China, and the data of State Statistics Bureau were shown, by the end of 2017
Bottom, 240,900,000 people of 60 one full year of life and the above population, accounts for the 17.3% of total population, wherein 158,310,000 people of 65 one full year of life and the above population, accounts for
The 11.4% of total population, being equivalent in every 9 people just has the old man of 1 over-65s, and the ratio is also in rising trend.And
Fracture problem caused by the osteoporosis that old man is faced is very significant, and the conservative therapy recovery period is very long, and stringent bed is extremely
It is 4 weeks few, then later period wearing brace, patient is beyond affordability, and the sleeping all kinds of complication that can cause patient long, such as pneumonia, urinary tract
Infection, thromboembolism, bedsore etc. are unfavorable for old man's rehabilitation.
With being constantly progressive for novel minimal invasive techniques, percutaneous vertbroplasty (percutaneous
Vertebroplasty, PVP) and balloon angioplasty balloon kyphoplasty (percutaneous kyphoplasty, PKP)
It is widely used to clinic, both technologies can be fast mainly as the novel Minimally Invasive Surgery for the treatment of Osteoporotic vertebral fracture
Speed relieves pain, and promotes patient's early functional exercise, therefore by the favor of doctor and patient.The operation will be special by small notch
Surgical instrument be placed on the position of patient's compression fracture (lesion), spinal compression position distraction reduction is injected into bone cement
(PKP), it or not struts by being directly injected into bone cement (PVP) after Postural reduction, compressed centrum is enable to reinforce, thus
Achieve the effect that relieve pain rapidly.The operative incision is small, and amount of bleeding is few, and operation generallys use local anaesthesia, operating time 20-
30min, postoperative patient release pain at once, restore that rapidly, the appropriate activity in ground can be descended within second day, curative effect is obvious, for many
Elderly patients with heavier complication are especially suitable.
Bone cement is the common first names of bone cement, is the common medical material of bone surgery, due to its part physical
Appearance and character there has been so popular title quite as building, white cement for decoration after matter and solidification.The master of bone cement
Wanting ingredient is polymethyl methacrylate, and in storing state, bone cement is by white powder and the colourless liquid two with penetrating odor
Certain formulations composition, as long as it is anti-that polymerization can occur at room temperature in use, by a certain percentage, they are poured on and is reconciled together
It answers.As mortar when reaction starts, and then such as gruel, it is the same then to become dough, can with kneading, be squeezed into arbitrary shape, most
Gradually solidify afterwards, whole process only has more than ten minutes.Bone cement undergoes wire drawing phase and dough period before solidification, and doctor need to be in wire drawing
Bone cement is pushed into lesions position by the phase, and until reaction terminates, local temperature is slightly increased, and feels some hot, this fixations
It is quite firm, more than ten years or even twenties years can be kept.
But PVP/PKP vertebral body operation in the prior art still has some shortcomings: (1) bone cement can in filling
It can leak, cause spinal cord or cauda equina compression into canalis spinalis, cause root compression into intervertebral foramen, cause into blood vessel
Blood vessel embolism such as pulmonary embolism, heart infarction etc. may cause serious or even threat to life complication；(2) bone cement is being filled
High pressure in Shi Yinqi centrum, fat drop or hemostasis block enter blood vessel, cause embolism may；(3) Cement fixation, Dispersed precipitate is not
Good, the combination for forming lumps and surrounding sclerotin is bad, and bone cement block occurs in Intrapyramidal fine motion, causes to hurt vertebra second fracture
It may；(4) bone cement polymerization reaction occurs in vivo generates heat, to peripheral nerve vascular tissue there may be burning, thus
Cause blood vesssls and nerves injuries may；(5) it reacts in vivo after bone cement injection and volatilizes noxious material, into blood or group
It knits, adverse effect is generated to body.
Application No. is 2015205000582 utility model patents to disclose a kind of bone cement directional injector, including bone
Cement injection device casing and bone cement injection device push rod；Bone cement injection device cannula tip side is provided with discharge
