A stopper for holding one part of a surgical needle assembly approximately fixed relative to another part. The stopper includes a planar rectangular body having two opposing faces and a protrusion that extends away from the body. The stopper may also include a groove that extends from the base of the protrusion to the top edge of the body. Each face typically includes a central depression configured for gripping by a finger or thumb. A needle assembly, for use with the stopper of the present invention, typically includes a hollow needle with a gripping member mounted on its proximal end, and a push rod configured to slidingly engage the hollow needle. The stopper is typically configured to fit snugly between the gripping member and the push rod to prevent movement of the push rod relative to the hollow needle during use.
