Title:

PUNCTURE NEEDLE FOR ENDOSCOPE

Document Type and Number:

Japanese Patent JP2016067431

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a puncture needle for an endoscope which is less likely to cause damage to an endoscope and a reduction in puncture performance.SOLUTION: A puncture needle for an endoscope includes a needle tube 3 which can be inserted in a channel 107 of an endoscope and has an opening 32 of an inclined plane shape at a distal end part and a needle slider which supports the needle tube to be rotatable by having a central line X1 of the needle tube 3 as a rotation center and moves the needle tube 3 in a direction of the central line X1 of the needle tube 3. The needle tube 3 rotates relative to the needle slider until a blade surface of the opening 32 substantially follows in an inclined direction of a distal end part of an angle tube 107b with respect to a proximal end part of the angle tube 107b as a part of the distal end part of the needle tube 3 receives pressing force from the channel 107 in a process in which the needle tube 3 passes through the angle tube 107b of the channel 107.SELECTED DRAWING: Figure 19
