摘要
穿刺力在不同的软组织内部表现的特征不同。进行穿刺针对软组织穿刺力模型的建立,可以对穿刺针在穿刺过程中的位置进行预判提供理论基础,提高穿刺精度,提高治疗效果。对中心静脉穿刺穿刺术进行分析,将穿刺过程分成4个阶段,并对每个阶段的力进行力学建模。搭建中心静脉穿刺试验平台,对穿刺过程中穿刺针力学模型进行验证,并对影响穿刺力大小的单因素进行了实验研究。实验结果表明随着穿刺角度的增大穿刺力也随之增大,随着穿刺针直径的变大,穿刺力也随之变大,穿刺速度的增大,穿对穿刺力影响较小。
The characteristics of puncture force in different soft tissues are different.The establishment of puncture force model for soft tissue can provide theoretical basis for the position prediction of puncture needle in the process of puncture,improve the accuracy of puncture and improve the treatment effect.In this paper,the central venipuncture is analyzed,the puncture process is divided into four stages,and the force of each stage is modeled.The mechanical model of puncture needle in the process of puncture was verified,and the single factor influencing the puncture force was studied.The experimental results show that the puncture force increases with the increase of the puncture angle,the puncture force increases with the increase of the diameter of the puncture needle,and the puncture speed has little influence on the puncture force.
