2 Dumont microsurgery forceps with microblunted, atraumatic tips Dumont #L5 Outils Dumont S.A., Switzerland, has supplied their regular forceps to the research and medical professions for many years. Now, in design collaboration with a foremost European supplier of microvascular instruments, Dumont puts their over one-hundred years of experience with hand fashioned tools into these precision instruments. The sides of these forceps are distinctively ribbed providing a better holding surface for maximum control of the instrument. The shanks are arched toward each other to transmit more holding strength to the points. The smooth inside surfaces at the tips will, with gentle pressure, close flat for 5 mm, increasing the total holding area considerably. The microscopically matched tips are gently blunted to prevent tissue puncture. The Inox steel alloy optimizes both stain resistance and hardness. From the middle of the shank to the tips of the instrument the inside and outside surfaces are highly finished under the microscope. These special microsurgery forceps are also recommended as micro needle holders because of their gently blunted, atraumatic tips.

9 DUMONT When choosing Dumont forceps, consider: 1. The style and shape of forceps you want 2. The fineness of the tips you require 3. The alloy best suited to your work Styles Dumont forceps come in a wide variety of shapes and sizes, from the world famous straight #5 to the extremely popular curved #7. Below you will find a brief description of the most popular styles. Dumont 2: Straight forceps with wide but thin tips often referred to as Mouse Laminectomy Forceps because of their popularity for breaking off delicate bone during mouse laminectomies. Dumont 3: Long straight forceps with course tips. Very popular in low magnification procedures or where longer, thicker forceps are needed. Dumont 4: Straight forceps very similar to the #5 but with broader shanks and a slightly courser tip. Dumont 5: The most popular style of Dumont straight forceps with fine tips which come in several styles including #55, #5CO, #5SF, #5XL and #5/45. 55: Similar to #5 but with lighter shanks which give the forceps a lighter spring action. 5CO: Similar to #55 but with even finer shanks producing the lightest spring action and longest meeting surface of any Dumont. 5SF: Standard #5 but with the finest tips ever produced by Dumont. 5XL: Similar to #5 but longer. 5/45: Standard #5 but angled 45. Dumont 6: Sharply angled forceps with courser tips. Perfect for access to difficult areas. Dumont 7: Large radius, curved forceps with fine tips. The most popular curved style. Medical: Available in almost any style. Denotes distinctive ribbing in the handle to maximize grip. Tip Profiles Once you have decided which style Dumont is right for you, choose the right tip profile for your application. While not all styles come in all tip profiles, below is a guide to help you decide which is right for you. The dimensions of these tips vary with each style. For specific dimensions please see each item. Standard The standard Dumont tips are designed for the most exacting work under the microscope. In general, standard tips are used under magnification up to 20X. Biologie The imprint Biologie identifies forceps especially produced for the biological sciences. In overall shape and dimension these forceps are identical in style but have the added feature of tips which are approximately twice as fine. Dumont s finest tips We are frequently asked for the Dumont forceps with the finest tip. These forceps are four times finer than Biologie tipped Dumonts. Please see page 87 and 91 for these items. Alloys Now that you have selected the right style and tip of forceps, you can move on to picking the right alloy for your application. Carbon Will stand hard use of the tips but has the disadvantages of staining easily, not being autoclavable, and being highly magnetic. Inox Is an alloy which has a certain amount of chromium added to carbon steel. This results in some loss of hardness but offers good stainless qualities. Inox forceps are magnetic. Dumoxel Is a patented Dumont alloy which provides optimal stainless steel features while still retaining adequate hardness. This combination makes it the most requested type of metal in Dumont forceps. Dumoxel is nonmagnetic. Titanium Forceps have several distinct advantages. They are fully corrosion resistant. For instance, salt water is non-reactive to this alloy. Although not as hard as it is a more flexible metal. It is also 40% lighter than stainless steel and 100% nonmagnetic. Dumostar After years of research and testing, Dumont has developed this advanced alloy for the express purpose of maintaining fine tips. Made of 40% cobalt, Dumostar is much more durable and elastic than the best stainless steels. It has a very high resistance to corrosive solvents such as sea water and strong acids and also has a temperature resistance of up to 550 C (1022 F). FST has tested Dumont s alloys in everyday use by some of our best customers and found Dumostar forceps to last, on average, four times longer than Dumoxel and Inox. We believe that, despite its higher initial cost, Dumostar is the most cost effective alloy for the research lab. Dumostar forceps are nonmagnetic.
