Percutaneous needle insertion has been widely used in many minimally invasive surgical procedures. These procedures involve inserting a long and slender needle to a target deep inside the body for either drug delivery or tissue sample removal. The success of these procedures often depends on the needle insertion force which is largely determined by the configuration of the cutting edge and the interaction between the cutting edge and tissue at the needle tip. Yet, there are very few results in the technical literature that address the cutting edge geometry and the mechanics of soft tissue cutting in needle insertion. This research aims to fill the gap and to advance the knowledge of needle insertion.

520 $a Percutaneous needle insertion has been widely used in many minimally invasive surgical procedures. These procedures involve inserting a long and slender needle to a target deep inside the body for either drug delivery or tissue sample removal. The success of these procedures often depends on the needle insertion force which is largely determined by the configuration of the cutting edge and the interaction between the cutting edge and tissue at the needle tip. Yet, there are very few results in the technical literature that address the cutting edge geometry and the mechanics of soft tissue cutting in needle insertion. This research aims to fill the gap and to advance the knowledge of needle insertion.
520 $a This work began by examining the cutting edge and cutting behavior of a blade. The parameters that influence tissue cutting were identified and the configuration of the cutting edge of a needle was defined by the identified parameters, i.e., the slice/push ratio, inclination angle, and included angle. The cutting edge geometry was analytically solved for various solid and hollow needles. The proposed general approach provides the foundation for designing needle tips with specific cutting edge properties.
520 $a The mechanics of soft tissue cutting in needle insertion was investigated using experimental, energy-based fracture mechanics, and numerical approaches. In particular, the effects of the slice/push ratio and the included angle on tissue cutting were examined. The studies advance fundamental understanding of soft tissue cutting in needle insertion and provide the foundation for advanced needle design and pre-operative insertion planning.
520 $a Inspired by the mosquito's maxilla which features micro-serrations on the cutting edge, the cutting behavior of serrated cutting edges was investigated. Laser micro-machining was used to create micro-serrations on the cutting edge of biopsy punches. Experimental and numerical studies were performed to analyze the cutting behavior. In addition, the frictional behavior between a surface textured needle and soft tissue was studied.
520 $a The results from this study will be useful for advanced needle design, pre-operative insertion planning, surgical simulation, and robot-assisted surgical procedures.
