Modeling and Analysis of Prostate Soft Tissue Puncture Performance using Puncture Needle

Applied Bionics and Biomechanics, Volume 2022, Issue 1, 2022., 2022
When treating prostate cancer, the use of puncture robots is an effective method to perform radioactive seed implantation surgery. However, when the puncture needle enters the lesion, the soft tissue is easily deformed owing to the complex force between the puncture needle and soft tissue, which leads to a puncture deviation between the needle tip and ...
