Abstract:
Objective Biodegradable is validated by the New Zealand rabbit femoral puncture mesh porous seepage prevention performance of the balloon.Methods The experiment was divided into the experimental group and control group, by piercing the New Zealand rabbit left leg near the femur, establish channel introduced after bone drill, fracture model is established, degradable mesh implant microporous balloon and/or bone cement.Observe and record the operation process of each New Zealand rabbit blood oxygen saturation change and cases of bone cement occur breakup and shortness of breath and groupings.Results Surgery under general anesthesia, bone cement injection process smoothly, balloon group of intraoperative breathing smooth, blood oxygen saturation has no obvious change; CPC group of blood oxygen saturation in the cement perfusion and perfusion after 81.63 +/-32.02, 32.02 +/-32.26, respectively, compared with perfusion 96.67 +/-1.71 in front of the difference is statistically significant, of which 3 cases died in 5 cases, shortness of breath, direct infusion of bone cement is more likely to lead to pulmonary embolism.Conclusions Further confirmed that the degradable mesh porous balloon seepage prevention of CPC and the breakup of the effect is obvious, comply with the design requirements.
