The House Suction 4" L with Obturator, 22ga is a specialized otologic surgical instrument designed for precision suctioning in delicate ear procedures. The 4-inch length provides adequate reach, while the 22-gauge refers to the small diameter of the suction tube, ideal for working in tight or sensitive areas of the ear canal or middle ear. The obturator helps guide the suction tube for accurate insertion and minimizes the risk of tissue damage during use.
