摘要： To develop a medical needle having a small protecting member that is not separate from a needle and a hub, is not obstructive to the performer during use, and is easy to switch from being in a usable state to being in a protective state.A pair of wings are pivotally connected to a hub provided at the tail end of a needle, the wings being provided on both sides of the axis of the needle; one or two or more link members are connected to the tip of each of the wings with joints interposed therebetween; the tips of the link members are pivotally connected to a cylindrical protecting member slidably fitted onto the needle; and, when the protecting member is moved toward the tip of the needle, the wings and the link members move in such directions as to become parallel to the needle while the protecting member comes to cover the tip of the needle, whereby the above object is solved.

摘要： A front portion of a tubular inner needle proximal end portion disposed at a proximal end of the inner needle is attached to a rear end portion of a tubular adaptor, a tubular outer needle proximal end portion disposed at a proximal end of the outer needle is inserted from a distal end of the adaptor, and a distal end of the inner needle is caused to protrude from a distal end of the outer needle. A restricting plate having an insertion hole through which the outer needle proximal end portion is inserted is inserted into the adaptor from an opening formed in an upper surface of the adaptor. A protrusion formed on a lower surface of the insertion hole protrudes upward and engages with one of the grooves of the outer needle proximal end portion. When the restricting plate is pushed down, the groove of the outer needle proximal end portion and the protrusion of the restricting plate are disengaged from each other and the inner needle is set to the unlocked state in which the inner needle is able to be advanced or retracted relative to the outer needle.

摘要： An unlocked state, in which an inner needle can be advanced or retracted relative to an outer needle, and a locked state, in which the inner needle cannot be advanced or retracted relative to the outer needle, can be switched by a simple operation without rotating an inner needle. A front portion of a tubular inner needle proximal end portion disposed at a proximal end of the inner needle is attached to a rear end portion of a tubular adaptor, a tubular outer needle proximal end portion disposed at a proximal end of the outer needle is inserted from a distal end of the adaptor, and a distal end of the inner needle is caused to protrude from a distal end of the outer needle. A plurality of grooves are formed in parallel in a peripheral direction in a lower surface of the outer needle proximal end portion, a restricting plate having an insertion hole through which the outer needle proximal end portion is inserted is inserted into the adaptor from an opening formed in an upper surface of the adaptor. A protrusion is formed on a lower surface of the insertion hole. The protrusion protrudes upward and engages with one of the grooves of the outer needle proximal end portion. When the restricting plate is pushed down, the groove of the outer needle proximal end portion and the protrusion of the restricting plate are disengaged from each other and the inner needle is set to the unlocked state in which the inner needle is able to be advanced or retracted relative to the outer needle, and when the pushing down is released, the restricting plate moves up and one of the grooves of the outer needle proximal end portion and the protrusion of the restricting plate are engaged with each other and the inner needle is set to the locked state.
