PUNCTURE TREATMENT TOOL

摘要

A puncture treatment tool includes a needle tube whose distal end is insertable into tissue, a cylindrical main body through which the needle tube is inserted, a needle stopper through which the main body is inserted and which is provided such that a position where the needle stopper is fixed to the main body can be changed in a direction of a longitudinal axis of the main body, and a slider which is fixed to a proximal end part of the needle tube, the slider being disposed to be operated movable relative to the main body. The slider is configured to be capable of selecting from a first state in which the slider is movable in the axial direction relatively to the main body without rotating in the circumferential direction of the main body, or a second state in which the slider is rotatable in the circumferential direction.

1. A puncture treatment tool comprising:
a needle tube whose distal end is insertable into tissue; a cylindrical main body through which a proximal end part of the needle tube is inserted; a needle stopper through which the main body is inserted and which is provided such that a position where the needle stopper is fixed to the main body can be changed in a direction of a longitudinal axis of the main body; and a slider which is fixed to a proximal end part of the needle tube, the slider being disposed to be operated movable relative to the main body at a position more proximal to the main body than the needle stopper in an axial direction of the needle tube, and a relative movement range of the slider with respect to the main body being determined by abutting against the needle stopper, wherein the slider is configured to be capable of selecting from a first state in which the slider is movable in the axial direction relative to the main body without rotating in a circumferential direction of the main body, or a second state in which the slider is rotatable in the circumferential direction relative to the main body.
