Description
Technical field
The utility model relates to a kind of vertebral plasty fluid pressure type bone cement stirring injection devices, belong to medical instrument neck
Domain.
Background technique
It is infused through puncture cannula after percutaneous puncture centrum currently, being mostly used for the treatment of Osteoporotic Vertebral Compression Fractures
The art formula for penetrating bone cement, after percutaneous vertbroplasty (Percutaneous Vertebroplasty, PVP), percutaneous vertebral body
Convex plasty (Percutaneous kyphoplasty, PKP) etc..By directly injecting bone cement in vertebra to hurting, or using special
Fixed bone dilator makes to hurt row bone cement injection again after vertebra height is restored.Domestic and foreign literature is to PVP, PKP to hurting vertebra height at present
Recovery have certain disagreement, but both can undeniably play a role to the recovery of vertebral height.PVP can pass through
The bone cement for injecting dough period increases the pressure of injection, reaches and preferably hurts the recovery of vertebra height.But current common bone water
The problem of mud device for casting is because of material, torsion, it is difficult to which the bone cement in dough later period is injected.PKP often utilizes balloon expandable
Make to hurt the recovery of vertebra height, unfavorable be on one side after balloon expandable around bone tissue compacting it is fine and close, bone cement is difficult to enter bone
Tissue space, reduces surface area of the bone cement in conjunction with bone tissue, and bone cement block easily forms micromotion hurting in vertebra, causes again
The generation of fracture.
Meanwhile the bone cement of application is resinae bone cement, liquid material has intense irritation smell, there is certain volatilization
Property and cytotoxicity, can lead to respiratory mucosa damage, lung tissue necrosis, oral inflammation, terminal nerve cacesthesia and liver poison
Property etc..And during bone cement stirring, the volatilization of monomer is also increased, causes operator to contact and sucks more monomers.
And bone cement is easily mixed into more gas, forms bubble in bone cement in stirring harmonic process, after being fed into and hurting vertebra,
Bubble can lead to local bone tissue and bone cement forms gap, cause combined surface area less, and binding force decline, bone cement block exists
Micromotion is generated in centrum too early, causes to hurt vertebra refracture.
