ABSTRACT:
An apparatus for connecting a thread wound on a bobbin to a surgical needle including feeding rollers for unwinding the thread from the bobbin, a tube-like chuck for selectively fix the thread thereto, a guide for guiding the front end of the thread, a feeding device for supporting the needle such that a hole formed in a rear end face of the needle is faced to the front end of the thread, and a clamping device having pushing rods for pressing the rear end of the needle to clamp the thread in the hole. By moving the needle to the guide, the front end of the thread is inserted into the hole of the needle, and then the clamping device is driven to press the rear end of the needle so that the thread is clamped in the hole. Then, the thread is unwound from the bobbin by a desired length by moving the feeding device away from the guide, and finally the thread is cut along an inclined line.
