Superior customer service. This design makes it easy to cut soft tissue without crushing. A Sure-cut scissor creates a sharp, clean, smooth cut. A scissor with two gold ring handles has tungsten carbide inserts on the blade edge. Carbide is a very hard metal that will maintain a sharp edge much longer than stainless steel. It is preferred for use in cutting cartilage and fur.
Roboz offers carbide instruments in forceps and needle holders as well. These instruments also are identified by gold handles. Tech Notes Tech Notes contain additional information on the features and applications of our instruments. There are 6 different alloys to choose from when selecting a micro tweezers. The information below is provided to help you compare the various alloys and their respective properties.
The six different alloys are carbon steel, titanium, stainless steel, Inox, Dumoxel, and Dumostar. Carbon Steel : At Rockwell 60, carbon steel is one of the hardest tweezers' materials. Carbon steel tips are very durable but the hardness makes carbon steel tips more brittle than other steels.
Carbon steel is also highly magnetic and stains easily. It will rust if exposed to water for any length of time. Titanium : While not as hard as some of the other alloys Rockwell 37 at the tips , titanium tips are very flexible. Titanium is extremely corrosion and stain resistant, making it the preferred choice for salt water uses. Titanium also has a high heat resistance, in excess of degrees Celsius, and is completely non-magnetic.
Stainless Steel : The common name for various alloys composed of carbon steel and chromium. There are many different types and grades of stainless steel. Alloys considered stainless exhibit good stain resistance and have varying degrees magnetism. Stainless steel is less likely to show damage but it can still rust, corrode, pit, and be affected by chemicals and environmental conditions. Inox : Inox is a specific stainless alloy composed of carbon steel and chromium.
Inox tips are more flexible than pure carbon steel but not as hard Rockwell Inox has good stain resistance and is magnetic. Dumoxel : One of the most popular tweezer alloys, Dumoxel is even more stain resistant than Inox and is highly corrosion resistant.
With a Rockwell 36 at the tips, tweezers made from this alloy have very soft, flexible tips. Dumoxel is non-magnetic and exhibits high temperature resistance. Dumostar : This new alloy is a blend of steel, chromium, nickel, and cobalt and has many of the best features of the other alloys.
Dumostar is heat resistant to over degrees Celsius and is completely non-magnetic. It is extremely corrosion resistant and is one of the harder alloys at Rockwell However, because of its unique composition, Dumostar tips are very flexible, are resistant to fatigue, and are capable of flexing far beyond other alloys without permanently deforming.
This alloy is far superior in overall performance than any other material available today! Micro tweezers are useful in a variety of different applications. Common uses include micro dissection of tissue and vessels, and processing tissue in electron microscopy procedures. Micro tweezers come in a wide variety of tip sizes, shapes, and materials. The type of cleaning and sterilization you require may affect the material you choose consult the Tweezers Material Reference Guide for a discussion of differences between tweezers' materials.
For example, if you require autoclaving and you are working under a microscope on a mouse the thinnest-tipped forceps made of stainless steel, titanium, Dumostar, INOX, and Dumoxel are good choices. Carbon steel instruments may not be the best choice for use where there is constant exposure to water.
If not handled properly, carbon steel is likely to rust if exposed to water for a length of time. Though not recommended by Roboz Surgical, flash flame decontamination could be used on carbon steel tweezers because this material is less likely to be damaged by high heat. The extreme heat from flash flame decontamination changes the molecular structure of most material adversely.
High heat softens metal and shortens the useful life of instruments. Consider another method of decontamination where lower heat levels can be applied such as the Roboz DS Germinator to keep your instruments useful for many more years. You will often see tweezers available in the Biologie pattern. Biologie tips are about twice as fine as standard tips. Some tweezers are available with a mirror finish and some in a matte finish.
Make a choice between the two finishes based on personal preferences- there is no quality difference between the two. A mirror finish may look clean and will be more reflective under bright light than a matte finish.
A Matte finish will not show smudges easily and the surface provides more of a grip. Both are high quality and protect the instrument equally.
The unique handle is designed to provide more "feel" and control at the tip. This handle also provides a better grip while wearing gloves. The tips are very fine and serrated and provide a sure, steady grip of tissue without trauma. The Foerester forceps are excellent for fine dissection of mice and dissection under a microscope.
Summary: The Singley forceps are designed to hold the heart of rats without the tip damaging the heart. The RS Singley heart holding forceps are designed to hold the heart of rats without being concerned about a sharp tip damaging the heart. A pin and screw allows you to adjust the opening of the tip to accommodate different size hearts.
The pin and screw also holds the tip steady and in position to keep your hands free to conduct other steps of the procedure. Summary: Round handled forceps can be used in a variety of surgical situations. Round handled forceps Roboz item numbers RS through RS can be used in a variety of surgical situations.
The feature of this instrument is its long, narrow tip which is helpful in procedures where you need to grasp and manipulate fine, small tissue in deep cavities. The unusual round, textured grip provides great control of the instrument and the tip.
The box style handle provides a "non slip" grip for even more control, particularly when wearing gloves. The round handle style is also manufactured in a spring action scissor Roboz item number RS As with the round handle forceps, fine tissue in a deep cavity is easier to manipulate and cut with a long narrow tip.
Summary: Tube occluding forceps are a useful tool where blockage of a tube is necessary. Tube occluding forceps can be used in almost any surgery where fluid or blood in tubes needs to be stopped. One such surgical procedure is when a perfusion is involved. During perfusions blood flow is re-directed from the heart to a series of tubes that directs the blood back to the patient's tissue.
The tube occluding forceps are ideal when flow of blood must temporarily be stopped. They tightly grasp the tube and can be set and kept in place.
