[0014] The mentioned invention is similar to our claimed one, but their main difference is that the mentioned patent’s ring is disposable and not adjustable, and our invention is designed for the sinuses and nasal passages of patients.

[0015] The claimed patent is a sinus and nasal cortico-sinus ring device with an adjustable cortico-monopolar angle and cautery, consisting of a handle, body, and ring-shaped end. The handle is eight centimeters long and features an electrical connector for monopolar cautery. It includes an adjustment screw for the ring, which is attached to the body near the ring's hinge. The ring has a 4 mm inner diameter which is blunt on the outside for safety, and sharp on the inside for mass removal. Only the ring part receives electric current for monopolar cautery, while the other parts are insulated.

[0016] The sinus and pituitary gland ring curette is a surgical instrument used to remove, or sample masses and tumors of the nose, sinuses, and pituitary gland. This device is manufactured by companies with different angles (slightly curved, severely curved, and straight). Since the anatomy of the nose and sinuses varies from person to person, prefabricated ring curettes are not suitable in all cases and the angle is appropriate. Using different curettes during surgery prolongs the duration of the surgery. Also, using the ring curette during surgery reduces the time spent in surgery and increases the number of injuries. This invention aims to overcome all these challenges and perform nose and sinus surgery with greater speed and accuracy, with fewer complications, and is suitable for all patients with different anatomies.Solution of Problem
