Abstract: A puncture needle includes a needle tube 1 provided with a spiral groove 3 and wall surfaces 3a and 3b of the spiral groove 3 serve as a surface for reflecting ultrasonic waves. The spiral groove is formed on the peripheral surface of the needle tube such that a grinding stone 2 is brought into contact with the peripheral surface of the needle tube while the needle tube 1 is being moved in its axial direction and rotated.The wall surfaces of the spiral groove formed on the needle tube serve as a reflection surface to change the orientation of the reflection surface in the axial direction of the needle tube according to change in position of the spiral. Therefore, even if a direction in which an ultrasonic wave is applied to the puncture needle is fixed, any portion of the reflection surface changing in orientation can become a surface for reflecting well ultrasonic waves, so that good ultrasonic waves can be obtained. The slant angles of the reflection surfaces in the axial direction of the needle tube can be changed by adjusting the moving speed in the axial direction of the needle tube or the rotation speed.
Abstract translation: 穿刺针包括设置有螺旋槽3的针管1，螺旋槽3的壁面3a，3b用作反射超声波的表面。 螺旋槽形成在针管的周面上，使得研磨石2在针管1沿其轴向移动并旋转时与针管的周面接触。 形成在针管上的螺旋槽的壁面作为反射面，根据螺旋位置的变化来改变反射面在针管的轴向上的取向。 因此，即使将超声波施加到穿刺针的方向固定，取向变化的反射面的任何部分都能成为反射良好的超声波的面，从而可以获得良好的超声波。 可以通过调整针管的轴向移动速度或转速来改变针管的轴向反射面的倾斜角度。

Abstract: An injection needle 1 made of an alloy containing cobalt and molybdenum is manufactured as follows. First, lancet cut is carried out to a pipe-like metallic material composed of the alloy containing cobalt and molybdenum to form a blade tip 3 and a blade part 5. Then, a distal end part 1A including the blade tip 3 is mechanically polished, and thereafter, the distal end part 1A is immersed in an electrolytic solution and electrolytically polished. Thus, burrs at the blade tip 3 or the like generated during mechanical polishing are removed. Since the injection needle 1 is composed of the alloy containing cobalt and molybdenum, compared to a conventional injection needle made of stainless steel, an injection needle in which surface roughness of an inner peripheral surface of the injection needle is low and smooth can be provided.
Abstract translation: 如下制造由含有钴和钼的合金制成的注射针1。 首先，对由含有钴和钼的合金构成的管状金属材料进行刺血针切割，以形成刀片尖端3和刀片部分5.然后，将包括刀尖3的前端部1A机械抛光， 然后，将前端部1A浸渍在电解液中进行电解抛光。 因此，在机械抛光期间产生的叶片尖端3等处的毛刺被去除。 由于注射针1由含有钴和钼的合金构成，所以与以往的注射针相比，可以提供注射针的内周面的表面粗糙度低且平滑的注射针。
