A sickle knife with suction is a surgical instrument used in otologic (ear) and other microsurgeries for precise and atraumatic dissection of delicate tissues, like those in the middle ear. Its primary use is to simultaneously cut tissue with the sickle-shaped blade and suction away debris or fluids through the integrated suction duct, which improves visibility and saves time.

Tissue dissection:

The sickle-shaped blade is designed for precise and sharp cutting of delicate structures, such as those found in the middle ear during procedures like tympanoplasty, stapedectomy, or myringotomy.

Concurrent suction:

The integrated suction function allows for simultaneous dissection and suctioning, which keeps the surgical field clear, improves visibility, and helps remove residual cholesteatoma.

Atraumatic cutting:

The design helps surgeons make clean cuts without causing extra trauma to the surrounding tissues.
