Abstract:
A needle position lock having a provision for selectively locking and unlocking the position of one or more needles in place therein to avoid inadvertent needle movements and positioning errors, comprising:a needle guide template which defines a hollow center for movably positioning therein at least one needle lock slide, wherein the needle guide template defines an array of close-fitting through-holes to guide needles inserted therethrough; each lock slide locks the position of one or more needles inserted into one or more aligned series of holes in the template, and comprises one or more columns of wedge clamp collars, wherein each wedge clamp collar defines a collar hole with a gap at one end thereof, and a portion of the collar hole inside the wedge clamp collar which is closer to the gap provides a slip fit for a needle, and a portion of the hole which is further from the gap is slightly smaller than the needle diameter, such that when the lock slide is translated within the needle guide template in the direction of the gap, the slightly smaller diameter portion of the wedge clamp collar clamps around a needle.
