The Proper Way to Hold Surgical Scissors

When searching for the best surgical scissors the market has to offer. One should keep in mind that maneuverability and control are essential. Surgical scissors may be used for sharp cutting & for blunt dissection.

Surgical scissors are made so that 3 force vectors can be used in cutting: torque, closing and shearing. These forces are transferred from the hand to the shanks, and then get a fulcrum to the cutting edges. The way the blades come together is by the closing force. Shearing is the force that pushes one blade flat up against the other while closing. Torque is when you use a motion to bring together the blade to touch the other blade. A lot of surgical scissor designers create these devices so when you move your hands in the right motion the cut automatically slices through perfectly.

When you cut, for best control and direction, its important to make certain the tissue is correctly located between the two blades & the security of the operator’s grip on the scissors & the more close the tissue is to the fulcrum, the more on this. The blades tend to push the tissue away, bunching it ahead of the cutting action of the blades. The more obtuse the angle between the blades when you cut. You will receive a non-accurate cut if try to steady the tissue, using the scissors.

To get a crisp, clean cut, try using the the grip that is designed to the three force vectors. The most common and greatest way to have these surgical instruments is by putting your ring finger through the rings and the ends of your thumbs holding the medical instruments & your index finger places near the fulcrum on the shanks. This grip gives the biggest type “tripod” & therefore gives the best stability for direction control. The, torque & closing forces; this is the grip which provides it much better control. The thumb & middle finger grip which gives your index finger a better support on both sides of the shanks. The resulting three-point grasp creates a smaller tripod as opposed to the previous method, there by getting it slightly more unstable.

Hold the surgical scissors in a cutting motion leaning forward, use your thumb-index grip. Such a grip uses only two-point direction control, this may cause a user to go off course. The force can be strong when closing, this grip applies the least shearing and torque forces of all grips possible for forward cutting. When you have less torque and shear the blades will tend to create a choppy motion in the cut like it was chewed as opposed to a nice clean cut.

The thumb-index finger grip used for cutting in a reverse direction. Such a grip applies three-point direction control with good lateral stability, but the shear and torque forces are virtually nonexistent, this tactic will require push cutting as a main technique.

The backhand grip is really a slight variation in the thumb-ring finger grip and is useful in cutting en route for the right.

All grips discusses to this point provide strong closing force. the best grip is the thumb-ring finger for better direction, torque and shear forces. If you cut backwards, the grip is most stable in direction control. The other two grips, when used in reverse cutting, you could lose control.
