In the ER, Sugical scissors are most commonly used for cutting. Most folks are right-handed which is why most surgical scissors are designed by the manufacturing company this way. The thumb-ring finger grip provides the greatest stability in direction control & applies maximal closing, torque & shear power using your natural grip movement of your right hand.
Even though you will find several sizes and shapes of surgical scissors, each of the surgical scissors have a name of a famous surgeon, there are basically 2 types: ones with curved blades & ones with straight blades.
The surgical scissors with the best mobility have curved blades, & visibility means you can have a smooth curve easily through tissue. The 15-20 degree scale of motion & visibility of structures over that found with straight surgical scissors. Curved surgical scissors are extremely useful deep in a wound where horizontal cutting with good visibility is best. When cutting through rough tissue, straight surgical scissors have a big advantage. In certain cases, straight surgical scissors can provide a more accurate straight cut than the curved ones. As opposed to straight scissors, curved surgical scissors have more of 30 to 40 degrees additional visibility and mobility.
A large selection of bone cutters are crucial surgical scissors for targeted purposes. Because of the resistance that bone offers to cutting, a plamed grip with surgical instruments, sometimes with 2 hands, is needed instead of the finger grip used with other surgical scissors. When the bone fragments spread. The jaws of the bone cutting medical tools close and easier with more tension. You should stear away the blade tips away from any type of material things you choose not to include in your cut. For example, while using rib cutters it is proper to point the shears perpendicular to the chest wall with the open blades beside rather than aimed toward the intercostals bundle. After starting a bite into the bone with rongeurs, kerrisons or other cutters, all of the tension at the wound is rest to ease, so that the surgical instrument will not slip deeper as the bite is completed. Security is thus gained when the only tension on the tissue is between the jaws of the surgical instruments.
If the flaccid tissue us effectively placed accurately between the surgical scissors then it can be slice just fine. Surgical scissors cutting employs closing strength, torque & shear to give an exact cut. Push-cutting allows straight cuts along the grain of a piece of tissue. "chewing it" happens when you jagged & crusehd wound stuck between the blades of surgical scissors lacking in cutting force.
When your cutting sutures with your scissor tip, hunt for the knot in between the slightly spread blades, rather than underneath the surgical scissors. Use the left hand, someone else, or another stable structure as a fulcrum to steady the scissors when making delicate cuts or when held by antoher person cutting sutures. When your cutting a row of sutures, hold the sutures in your left hand so that each one becomes taut as you cut it & they do this so that the cut sutures are held out of the way.
By seperating the scissors while inside the tissue planes, blunt cutting can be done or by achieving a probe or rake by using surgical scissors. Its sometimes ok to do blind cutting when its useful in between tissue plane structures. for better maneuverabilty & visibilty use curved scissors, Straight surgical scissors give the best possible mechanical advantadge when cutting through thick, tough skin.
