Abstract
A tattoo needle assembly has a housing comprising a longitudinal channel, a needle bundle mounted in the longitudinal channel and reciprocally movable between a retracted position and an extended position, and a biasing member engaged with the housing and the needle bundle for biasing the needle bundle at least radially to an inner wall of the housing. The housing comprises first and second guide surfaces forming a V-shaped guideway on the inner wall. The needle bundle comprises first and second sliding surfaces for slidably engaging the guideway. The biasing member radially biases the needle bundle to slidably engage the guideway such that the guide surfaces of the guideway and the sliding surfaces of the needle bundle form a V-V sliding pair during reciprocal movement of the needle bundle between the retracted position and the extended position.
