RI-000025 The use of alm retractors as a surgical tool allows for improved sight and access to the surgical area while holding back tissue. The retractor’s blades are described as having “4×4 teeth” because there are four teeth on each side of each blade. Compared to smooth blades, which can slip or slide during surgery, these teeth aid to hold tissue more firmly. These retractors normally have a handle on one end and a spoon-shaped blade on the other. They are made of high-quality stainless steel. The blade’s gentle holdback of the incision’s edges enables the surgeon to operate with greater accuracy and precision.
