Minimally invasive vas surgery using a newly designed double-ringed clamp

We have recently designed a novel surgical instrument, a double-ringed clamp (Moon's clamp), with which the vas deferens can be located and isolated both simply and safely while minimizing unnecessary injury to the surrounding tissue.

With the use of the Moon's clamp, we successfully performed 1,140 cases of simplified, minimally invasive vasectomy and 216 cases of mini-incision vasectomy reversals (vasovasostomies) without any significant complications.

This surgical technique, using Moon's clamp, may be effective in reducing the operative time, the postoperative complications and the recovery time after different types of vas surgeries, such as vasectomy or vasectomy reversal.
