HEISTER, MOUTH GAG RETRACTOR FOR JAW OPENING

A Heister Mouth Gag is a surgical instrument used to hold open the mouth during certain procedures.

The Heister Mouth Gag typically has a U-shaped design with two arms that fit inside the mouth. The gag is activated by a screw mechanism, which gently opens the mouth to the desired width. The arms are often padded to reduce discomfort and prevent damage to the teeth and gums.
