Holmgren Speculum

The Holmgren Speculum is a self-adjusting, self-retaining auditory speculum. By tightening the screw provided for this purpose, the flanges may be made to move apart. This speculum can also be used for ear-related surgical operations. It can stay in a position that allows the surgeon to execute the surgical operation with both hands free since it is self-retaining. This Holmgren Speculum helps to see the tympanic membrane by straightening the external auditory canal and holding the cartilaginous component of the external auditory canal apart.
