[0003] As is well known, medical practitioners use surgical instruments to assist in performing surgical procedures. Surgical instruments are used to manipulate the surgical site on a patient. The practitioner must place the surgical instrument on the patient where the instrument will perform the medical or surgical procedure. Endoscopic surgery is becoming increasingly popular to perform a variety of surgical procedures. In endoscopic surgery, a portal is created in the patient. Through a small incision or through a patient's biological opening, for example, the nasal cavity in sinus surgery , the surgical site is accessed. It is a device that allows medical personnel to view the surgical site. An endoscope is inserted into one of the portals or nasal passages. It is used to perform certain surgical procedures. The surgical instruments used are inserted through the endoscope or other portals. Through the endoscope, surgical instruments are manipulated to perform the surgical procedure. The advantage of performing endoscopic surgery is that it requires no perioperative space to access the surgical site. Minimizing the extent of tissue damage and therefore the time required for post-operative healing Furthermore, during endoscopic surgery, only a relatively small portion of the patient's internal organs and tissues are visible. This minimal exposure of the patient's body prevents irritation to the patient's organs and tissues. This reduces exposure to dyes.

[0004] The ability to perform endoscopic surgery is facilitated by the use of powered surgical tools specifically designed to perform endoscopic surgery.
