Description
the application is the divisional application of following patent application:
(1) applying date: on November 28th, 2012
(2) application number: 201210496696.2
(3) invention and created name: the fixed closed device of the netted sacculus of degradable macromolecule and conveyer device thereof
Technical field
The present invention relates to the supporting operating equipment of the netted sacculus of degradable macromolecule, be specifically related to fixed closed device and the conveyer device thereof of the netted sacculus of degradable macromolecule.
Background technology
Wound, disease (as systemic disease, tumor etc.) and osteoporosis all can cause vertebral fracture.Caused by vertebral fracture have an intense pain and limitation of activity makes quality of life of patients decline, and have the possibility of other pathological changes of secondary, even cause paraplegia and death.Desirable Therapeutic Method should be able to alleviate rapidly because of the pain caused of fracturing, and can correct because of the spinal anterior approach caused of fracturing, recover patient activity ability as early as possible.Currently mainly contain three kinds of Therapeutic Method: traditional conservative therapy, the treatment of conventional surgical open surgery and minimal invasive operation.With other two kinds of Measures compare, minimal invasive operation treatment time is short, and wound is little, and pain is little, and blood loss is few, and recovery time is short and the hospital stays is short, is thus widely used gradually and will becomes following main flow Therapeutic Method.
Minimal invasive operation such as percutaneous vertbroplasty (PVP) and Percutaneous kyplasty (PKP) are directly thrust in the vertebral body of fracture by puncture needle percutaneous, direct injection bone cement or the bone cement that reinjects after expanding with dilator, the vertebral height of fracture is made to obtain recovery to a certain extent, rapid reinforcement vertebral body, reaches the object relieving the pain and reactivate as early as possible.Mainly there are two class problems in current minimal invasive operation, one is the bone cement that uses is acrylic resin bone cement and the problem that causes, and two is that bone cement is revealed and the problem that causes.Acrylic resin bone cement hardness is large and to osteogenesis without facilitation, the appearance that contiguous vertebral body secondary fracture and vertebral body crack can be caused to levy, can not be applied to youngster.Therefore the Clinical practice exploring other bone cement substitutes is needed.
Calcium phosphate bone cement has microcellular structure and calcium component, thus has a lot of advantage, as short osteogenesis, is conducive to growing into of new bone, the recovery etc. of vertebral bone quality and height.But water is defeated and dispersed, bearing capacity is low cannot be applied in vertebral body operation because it is met.Some equipment are developed and reduce the defeated and dispersed of bone cement clinically.As TaiWan, China Guanyasheng Technology Corp. (A-Spine Asia) develops a kind of Vessel-X filling mesh bag (Spine.2007; 32:2076-2082), this mesh bag forms Double-level Reticulated pore structure by non-stretchable polyethylene terephthalate.The people such as nearest Rotter R. (Eur.Spine J.2010; 19:916-923) leave a kind of metal net support.But these supports are non-stretchable, and thus non-degradable may bring long-term risk.In addition, Vessel-X filling mesh bag and metal net support mesh size are respectively 100 μm and 100mm level, the chance water of calcium phosphate bone cement may not be stoped defeated and dispersed, thus can not be applied to the Clinical practice of calcium phosphate bone cement.In theory, if calcium phosphate bone cement is injected in biodegradable and biocompatible sacculus, two limitation of calcium phosphate bone cement can be suppressed.And in the degradation process of this sacculus, calcium phosphate bone cement can be exposed to the bone of surrounding by gradual burst, thus can remain with the short osteogenesis advantage of calcium phosphate bone cement.
For this situation, it take block copolymer as all good netted sacculus of hollow degradable macromolecule of the biocompatibility of raw material and elasticity that inventor have developed a kind of, and this sacculus internal diameter is 1-10mm, and balloon membrane THICKNESS CONTROL is at 0.1 ~ 0.2mm; The diameter forming the fiber of sacculus is 0.2-1.5 μm.This netted sacculus has good biocompatibility.Bone cement and body fluid can be stoped directly to contact but calcium ion in bone cement can be made to discharge in body fluid via balloon wall.Sacculus burst pressure is 6-20atm, the vertebral height of compression can be made to be able to lifting and recover even completely.Degrading quality in simulated body fluid, lipase, human serum in 35 days is 10 ~ 20%.Therefore, described sacculus solves the defeated and dispersed and seepage of calcium phosphate bone cement, can not the problem such as load-bearing, also can maintain the advantage of calcium phosphate bone cement, release calcium ion, promote the generation of new bone, and avoid second operation clinically, be conducive to the recovery of patient.Both made up PVP, PKP defect, expand again the operation scope of application, and the preparation process of this sacculus had been simple.Thus the netted sacculus of degradable macromolecule has obvious application prospect.
The netted sacculus of degradable macromolecule in use needs implantation to hinder vertebra and closes tail end, thus avoid bone cement excessive from sacculus tail end, reduce bone cement and body fluid too much spend contact and cause defeated and dispersed, ensure to keep swelling state after perfusion bone cement in sacculus, thus the height can avoided withdrawing from bone dilator in other modes of PKP and cause is lost always.
Therefore, be necessary to design a kind of fixed closed device of matching with the netted sacculus of degradable macromolecule and conveyer device thereof.
