Patent number: 5618261Abstract: An eye proptosing speculum that applies pressure to urge the eyeball outwardly is disclosed. The speculum includes a pair of blades and a pair of pressors. The pair of blades are opposingly situated and extend generally posteriorly. Each blade is shaped to engage the patient between one of the eyelids and the eyeball. The pair of pressors are also opposingly situated and extend generally posteriorly. One pressor extends from each blade and each pressor is shaped to engage and to exert pressure on the peripheral orbital contents. The pressure is transferred to the posterior orbital contents and then to a posterior region of the eyeball to proptose the eyeball outwardly. Each blade and each pressor, in combination, generally extend to follow the exterior surface of the eyeball, and each blade and each pressor is shaped to minimize extrinsic pressure directly on the eyeball.Type: GrantFiled: October 27, 1994Date of Patent: April 8, 1997Inventor: Herbert J. Nevyas

Patent number: 5545122Abstract: A speculum comprises a pair of elongated blades having elongated hollow bills therein. Each bill is at least partly covered by a flexible expandable bladder. One or more ports communicate between the interior of each bill and the interior of the bladder. Gas lines are connected to each bill for supplying compressed gas to a valve to each bill to expand each bladder. A second valve can be activated for deflating each bladder. For use, the speculum blades are inserted into a body cavity and the bladders inflated to gently expand the body cavity. Blades can then be moved apart to perform an examination. When the examination is completed, the blades are moved toward each other and the bladders are deflated before the blades are withdrawn from the body cavity.Type: GrantFiled: October 12, 1994Date of Patent: August 13, 1996Inventor: Theresa Spruill

Patent number: 5529358Abstract: A halo style surgical retractor having fixed and movable curvilinear members each of which has an outwardly directed retractor channel extending over the full length of the member. A support arm is attached to the fixed member to hold the fixed member in a desired fixed, but adjustable position. The ends of fixed and movable members are coupled together so that, first, when the members are brought into a generally coplanar relationship, there is an uninterrupted and continuous retractor holder path around the combined length of the fixed and movable members. Second, the couplings permit the movable member to pivot to a position directly above and overlaying with the fixed retractor member, that is, a position in which the movable retractor member is in a plane directly above and generally parallel to the plane of the fixed retractor member.Type: GrantFiled: September 30, 1994Date of Patent: June 25, 1996Assignee: Ohio Medical Instrument CompanyInventors: Charles Dinkler, Richard B.
