ABSTRACT:
A needle bending device for bending a needle to any desired length without damaging the lumen of the needle and while maintaining sterile conditions, comprise a plastic casing having an open aperture and elongated chamber. The chamber is maintained sterile and the aperture is provided with a curved crown so that the needle can be bent around the crown. Graduated markings on the outer surface of the casing can be used in conjunction with transparent material for the casing, to see the length of needle within the casing and provide a bend of suitable length. Bends having angles of 90.degree., more than 90.degree. or less than 90.degree. can also be provided by bending the needle to any desired extent around the curved crown.
