Microdevices are one of the most useful technical advances introduced in the field of rhinology following their use in areas such as orthopaedics and plastic surgery. It is an ENT Instruments that has been used in nasal and endoscopic sinus procedures and tonsillectomy in recent decades. The advantage of microabrasion is a shorter, more precise and less traumatic procedure for the patient. The Three Main Components of The Microdebrider The microdebrider is a tubular device with a hollow tube. At the end of the tube is a blade that cuts the tissue to be removed, with the blades moving back and forth. The faster the blades move, the smaller the pieces cut. If the blades move more slowly, larger pieces are cut. The dimensions of the cut tissues are good enough for use in histopathology, etc. The blade is integrated with a suction mechanism that continuously pulls the tissue to be cut and removed from the surgical site. The Microdebrider consists of three main parts. 1. The Blade (or paddle) - is a hollow metal tube, serrated or smooth, with a suction port. The suction draws the fabric into the blade port, which cuts the fabric. The design of the blade ensures that the tissue is cut and suctioned from the puncture site. The blades are available in different sizes. They are disposable and should be replaced after each use. The blades can rotate at different speeds in direct, reverse or oscillating directions. The latest developments in blades include the possibility of cauterisation and longer blades. Thus, bipolar blades help to cauterise or coagulate at the same time. The advantage is less bleeding and cleaner, more efficient operation. These blades can essentially perform all three functions, namely cutting, suction and cauterisation/coagulation. Longer blades help to reach deeper lesions and tissues. 2. Nozzle - The nozzle holds and regulates the blade and suction action to remove debris quickly and simultaneously and give the surgeon better visibility during subsequent work. The handle can accommodate blades of different sizes and configurations. The suction tube is attached to the handle. 3. Console (foot pedal control) - The surgeon adjusts the speed and direction of blade rotation using the foot pedal and the parameters are displayed on the console. The most commonly used surgical instruments for sinus surgery are:
The most commonly used Chisels and Cutters
Prior to the use of microabsorbents, cavity surgeries were performed with rags and forceps. This was essentially a manual method of removing bone and tissue from the nasal cavity and sinuses. Electric drills were also used. In current practice, surgeons still use a combination of scissors, micro drills and forceps as needed. What are the advantages of using a microdrill?
