Description
Technical field
The present invention relates to a kind of bone filler delivery cannula, a kind of bone filler delivery cannula of particularly in percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty art (PKP), using.
Background technology
Because the compression fracture of vertabral body that osteoporosis causes is mainly among the old people; Along with aging deepens continuously; The patient who suffers from this disease is also increasing sharply, and percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty art (PKP) have been brought into play irreplaceable effect therein.At present; The bone filler delivery cannula is widely used in the vertebroplasty, under image documentation equipment is kept watch on, in the spongy bone gap of vertebra, injects implant (like bone cement) by external force; Reach the reparation vertebral height; Strengthen intensity and the stability of vertebral body, the reduction of patient lumbar and back pain, thus treatment is because the purpose of the compression fracture of vertabral body that osteoporosis causes.。
Domestic at present in vertebroplasty (PVP or PKP) head end (far-end) of employed bone filler delivery cannula be flat, can't be crooked.For example the patent No. is that 200720060062.7 one Chinese patent application discloses a kind of percutaneous vertebral plasty operating theater instruments, and wherein described bone filler carrier pipe is exactly straight unyielding.In operation process, generally keep the stress balance on the vertebral body biomechanics, and traditional bone filler carrier pipe can only be used for the conveying with the pleurocentrum bone filler in the inner mode that adopts symmetry to inject bone filler of vertebral body; So every joint vertebral body all will carry out twice puncture; Inject bone filler then, operating time is longer, and is bigger to patient's wound; Complication rate is higher, and has increased patient's financial burden.More obvious for the above-mentioned defective of the patient of many vertebral bodys pathological changes.
In addition in the PKP art; The conventional surgical step is at first to set up the service aisle that gets into vertebral body; Secondly expand the expanding channel of vertebral body dilating sacculus with bone drill, after bone drill is withdrawn from sacculus is sent into the inner and expansion of vertebral body, then the sacculus negative pressure is withdrawn from; Flat bone filler delivery cannula is sent into the inner bone filler that injects of vertebral body, at last all apparatuses are withdrawn from.This mode complex steps, the operating time is long, uses apparatus more, and patient's financial burden is heavier.
To the problems of the prior art, need a kind of can the use flexibly badly, easy to operate, complication rate is low, can reduce the bone filler carrier pipe of surgery cost.
Summary of the invention
The purpose of this invention is to provide a kind of can the use flexibly, easy to operate, simple in structure, lower-cost bone filler delivery cannula.The present invention becomes flexible pipe through the remote design with carrier pipe; And insert the sheath core that a far-end has fixed angle in that carrier pipe is inner; Make that the far-end of carrier pipe is crooked; And the relative position of the fixed bend tune that the patient can be through controlling said sheath core and the flexible pipe of delivery tube reaches the purpose of control delivery tube degree of crook, and apparatus also has the effect of leaving cavity in vertebral body inside.
The objective of the invention is to realize through following technical scheme:
