Description
Technical field
The invention belongs to the field of medical instrument technology, more particularly to a kind of multi-functional centrum used in vertebroplasty
Shape instrument.
Background technique
Osteoporotic vertebral fracture is the common disease for endangering middle-aged and the old's health, for vertebral compression bone
Folding, traditional treatment method is based on conservative, including lies up, is drug analgesic, fixed etc. outside brace, easily lead to bone amount into
One step is lost, and aggravates osteoporosis, to form vicious circle；And open surgery is often in poor shape because of systemic, spiral shell
It is insufficient to follow closely fixing intensity, easily leads to Unstable internal fixation.
Report within Charles Robert Richet Deramond etc. 1987 invading using percutaneous vertbroplasty (PVP) treatment C2 centrum
Attacking property hemangioma achieves good curative effect.Hereafter, which is also applied to Vertebral malignant tumorss and osteoporosis.It should
The shortcoming of operation is can only to make to hurt vertebra by deformity fixation and relieve pain, and cannot restore vertebral height and correct humpback
Deformity, and due to the low viscosity bone cement of direct injection into vertebral cancellous bone at elevated pressures, it is more difficult to its flowing is controlled,
Bone cement percolation ratio is higher, and document report is 30%~67%.By 1994, American scholar Reiley etc. on the basis of PVP,
It devises through balloon expandable and corrects the technology of kyphosis deformity, become percutaneous kyphoplasty (PKP), in
Clinic was applied to by FDA approval in 1998.A kind of balloon-expandable is placed in the vertebra collapsed using percutaneous puncture by the technology
Body is lifted soleplate by the expansion of sacculus, replys the height of centrum, correct kyphosis deformity, and form a surrounding in centrum
For the cavity of bone shell, high viscous bone cement is perfused at low pressures.In order to make sacculus smoothly enter centrum, need first to use
Puncture needle and working column establish service aisle, then reuse bone drill and drill out work cavity of the sacculus before expansion, then by ball
Capsule is sent into centrum, withdraws from sacculus after forming the cavity that a surrounding is bone shell in centrum, finally injects bone cement, operation step
It is rapid cumbersome；Simultaneously as the reason of vertebral body structure, in order to keep the stress balance in centrum biomethanics, every section centrum is all needed
Carry out the balloon expandable and injection bone cement of bilateral.Operation requires to operate in the case where X-ray monitors, the surgical procedure more cumbersome time
The longer health damage to doctor is bigger, physical fitness requirement is higher；Bilateral carries out balloon expandable and injection bone cement to patient trauma
Greatly, complication chance of occurrence is high, also increases the financial burden of patient, and disadvantages mentioned above becomes in the case where more piece Vertebral body
It obtains more prominent.
For disadvantages mentioned above, the Chinese patent of Patent No. 201310671713.6 discloses a kind of vertebral body balloon expansion system
System, devises hard end socket, protects the casing and lining core of sacculus, under the booster action of lining core, before expansion is opened in realization
Service aisle, the distal end of sacculus is fixedly connected with the closed end socket in distal end, firstly, the remote of sacculus is arranged in the end socket of this technology
End, the position that balloon distal is connected with end socket are related to the sealing problem of balloon expandable, have certain seep in balloon expandable
It leaks out danger, secondly, this technology is to open working path and expansion before realizing expansion, is not carried out the filling function of bone filler,
The financial burden of the reduction patient in maximum magnitude is not accomplished.
For the problems of the prior art, a kind of using flexible is needed, it is easy to operate, operating time can be shortened, reduced
Operation risk, reduce patient economy burden, begin to speak, balloon expandable and convey filler one multi-functional vertebral body shaper
Tool.
