Sklar's Jacobson Microvascular Needle Holder is primarily used for suturing in microvascular and cardiovascular procedures. It may also be known as a Jacobson-Castroviejo Needle Holder. The finely cross-serrated, tapered jaws are able to securely hold very fine sutures. Serrations on instruments are designed to stay sharp for a significantly longer period of time than standard instruments. This product is straight with micro-profile, cross-serrated jaws and an overall length of 8-1/2 inches. It also features a locking mechanism.
