A neurostimulation trocar assembly (500) for insertion into tissue of a patient is disclosed, the neurostimulation trocar assembly comprising an elongate trocar body (510) and a neurostimulator (550). The trocar body (510) extends from a proximal tip (511) to a distal tip (512) and has an elongated open channel (520) extending along a length of the trocar body (510). The nerve stimulator (550) has a shaft (560) extending from a proximal end (561) to a distal end (562) and at least one electrode (570) at or adjacent to the distal end (562) of the shaft (560). The open channel (520) of the trocar body (510) is configured to receive both a catheter tubing and the shaft (560) of the nerve stimulator (550) such that the catheter is releasably secured between the trocar body (510) and the nerve stimulator (550) in an assembled configuration. A trocar assembly and a method for positioning a catheter in a target tissue site are also disclosed. 公开了一种用于插入到患者的组织中的神经刺激套管针组合件(500)，所述神经刺激套管针组合件包含细长套管针主体(510)和神经刺激器(550)。所述套
