Description
Technical field
This utility model relates to technical field of medical equipment, is specifically related to a kind of adjustable high-pressure expanding ball pouch.
Background technology
Current reply compression fracture of vertabral body the best way mainly contains percutaneous vertbroplasty and Percutaneous kyplasty, wherein uses more with vertebroplasty, applies wider.Since 1984 start to occur first case percutaneous vertbroplasty, improvement for vertebroplasty is all continuing always, and percutaneous vertbroplasty is all generally set up passage and input bone cement (such as polymetylmethacrylate) to enter in vertebral body for a long time, to provide support force enough between bone trabecula in vertebral body, thus ensure that compression fracture and pain no longer occur disease vertebra.But this kind of operation still to there is bone cement seepage uncontrollable, thus easily cause the complication after bone cement seepage, jeopardize the life security of patient.
The best mode solving this problem is at present then a kind of expansiveness expansion bone sacculus of American physician exploitation in 1999, its principle carries out punching press expansion for filling device to placing into Intrapyramidal sacculus utricule by pressure, thus expand certain cavity, make bone cement major part be distributed within the scope of this cavity, can not because of have the spongy bone such as bone trabecula stop and toward the uncontrolled flowing of surrounding.After filling this cavity full, then toward surrounding disperse, play the risk reducing bone cement seepage further, and can improve and recover the height of compressed vertebral, the change of minimizing later stage biomechanics and the possibility of vicious cycle that causes.
But above-mentioned expansiveness expands bone sacculus except having the function of recovery vertebral height, also there are some defects that cannot avoid:
Defect 1, the material that expansiveness expands bone sacculus is mostly the materials such as polyether-polyurethane, and this kind of toughness of material foot, intensity is large, can deformation.But still there is wedge angle in vertebral body and comparatively firm bone trabecula tissue, this class loading likely there will be the effect of similar " bony spur ".When balloon expandable, this kind of bony spur easily causes breaking of sacculus utricule, and contrast agent leaks.And most of contrast agent all needs to carry out iodine test before use, if when the contrast agent flowed out runs into iodine test patient only, will occur certain complication, operation risk increases;
Defect 2, carries out the safety of Cement fixation after balloon expandable, although lower than directly injecting the risk of leakage that bone cement causes, still there is the risk of bone cement seepage, as pouch product, cannot reduce the percolation ratio of bone cement.And the complication that the seepage of bone cement causes is often all comparatively serious, or paralysing or pulmonary infarction or lethal, is all very bad;
Separately attached, in order to solve the bone cement risk of leakage of percutaneous vertbroplasty as much as possible, application number is the patent of CN1552290A, provide a kind of using method of vertebra filling device, it comprises a filling member, include a holding part and an inlet, this filling member is made up of the flexible non-airtight leg of plurality of through holes one or plural mask, and aperture is not more than 0.1mm.Because aperture is less, thus necessarily can limit bone cement disperse, hold onto all bone cements in this leg, thus improve operation safety.
But, also there is following defect in the filling device that above-mentioned patent proposes:
Defect 1, this filling device is only a filling device, when corresponding medical pulp is filled, and unlike expansiveness expands bone sacculus, having supporting pressure to fill device provides enough pressure to carry out expanse, thus can while vertebral body inner support opens a safe cavity can carried for bone cement, the vertebral body of the compressibility damage because causing by external force pressure can also be recovered to a certain extent, make upper and lower soleplate more trend towards parallel state, reduce the risk of same vertebral body secondary compression fracture of vertabral body further.Because the filling device that this patent proposes not is obturator, so the effect of this pressure expansion cannot be realized.Only just wrap bone cement, but itself there is no pressure to fill device and carry out expanse, by the mode of hand push conveying bone cement, cannot expand and prop up vertebral body, but use the words of some bone cement carriers, also due to leg pouch, inherently tool is pertusate, to support greatly the while of really cannot realizing Cement fixation as sacculus, and this kind of bone cement conveyer device struts intensity also far away not as good as strutting intensity in balloon-expandable to pouch, namely final vertebral height cannot realize real recovery.
Defect 2, this filling device of expansion is suppressed just because of cannot use, particularly when the compression fracture of vertabral body time slightly for a long time a bit (but non-old fracture) or osteoporosis degree is not serious, leg pouch is difficult to well fill bone cement and strut more.Resistance is too large, and strong support can cause certain operation risk, finally causes Cement fixation quantity not sufficient, and therapeutic effect is not good.
Defect 3, this pouch patent is at present without good disperse effect.Too small due to aperture, bone cement is extremely difficult, and from this filling device, disperse is out, namely do not exist to be formed to inlay between bone cement with substantia trabecularis ossium bone and be connected, direct result by be expanded state filling device in filled up bone cement, in a mellow and full bone cement lump of oval.Although certain supporting role can be played, but due to not enough with substantia trabecularis ossium bone contact area, degree of inlaying is inadequate, certain movable property can be there is when body movement, and due to surrounding be all the spongy bone of osteoporosis class, more easily occur that bone cement clashes into the bone trabecula of bordering on around and causes local secondary fracture, this bone cement block strengthens in Intrapyramidal zone of action, and activeness improves.And then once the activeness of this bone cement block is larger, the probability that secondary fracture and bone cement block clash into cortical bone also just substantially increases, and operation risk increases again.
Therefore, pouch and sacculus product all have self advantage and effect, but all have certain defect, and safety all cannot realize higher embodiment,
