摘要: We present the tip and friction forces acting on a needle during penetration into canine prostate, independently measured by 7-axis load cell newly developed for this purpose. This experimental apparatus clarifies mechanics of penetration, potentially improving development surgical simulations. The behavior both can be used to determine mechanical characteristics prostate tissue upon detection surface puncture, which appears in force, makes it possible estimate true insertion depth tissue. model caused clamping force also determined from forces.
