Claim 1
Independent Claim
280 words
A myringotomy tube inserter for inserting a myringotomy tube in an incision in the tympanic membrane of a patient's ear, comprising: an elongated hollow tubular sleeve member including a first handle non-rotatably attached to said sleeve member for holding and manipulating said inserter; a shaft member positioned within said sleeve member and having a proximal end extending from one end of said sleeve member and a distal end extending from the other end of said sleeve member, said shaft member independently movable both longitudinally and rotationally within said sleeve member, said shaft member distal end adapted to releasably hold a myringotomy tube adjacent said sleeve member other end, said shaft member proximal end terminating in an enlarged head portion adapted for gripping to enable rotation of said shaft member with respect to said sleeve member, such rotation being effective to rotate a myringotomy tube, releasably held on said distal end of said shaft member, relative to said sleeve member to permit said sleeve member and said first handle to remain in a fixed orientation as said shaft member and the myringotomy tube are rotated; and means for urging said shaft member longitudinally with respect to said sleeve member to withdraw said shaft member distal end within said sleeve member to cause said sleeve member other end to exert pressure against a myringotomy tube releasably held on said shaft member distal end, releasing the tube from said shaft member, rotation of said shaft member during insertion of the myringotomy tube into an incision in the tympanic membrane aiding such insertion, said urging means being operable upon such insertion to retract said distal end of said shaft member from the myringotomy tube.
Claim 2

A myringotomy tube inserter for inserting a myringotomy tube in an incision in the tympanic membrane of a patient's ear, comprising: an elongated hollow tubular sleeve member including a first handle non-rotatably attached to said sleeve member for holding and manipulating said inserter; a shaft member positioned within said sleeve member and having a proximal end extending from one end of said sleeve member and a distal end extending from the other end of said sleeve member, said shaft member independently movable both longitudinally and rotationally within said sleeve member, said shaft member distal end adapted to releasably hold a myringotomy tube adjacent said sleeve member other end, said shaft member proximal end terminating in an enlarged head portion adapted for gripping to enable rotation of said shaft member with respect to said sleeve member, such rotation being effective to rotate a myringotomy tube, releasably held on said distal end of said shaft member, relative to said sleeve member to permit said sleeve member and said first handle to remain in a fixed orientation as said shaft member and the myringotomy tube are rotated; and means for urging said shaft member longitudinally with respect to said sleeve member to withdraw said shaft member distal end within said sleeve member to cause said sleeve member other end to exert pressure against a myringotomy tube releasably held on said shaft member distal end, releasing the tube from said shaft member, rotation of said shaft member during insertion of the myringotomy tube into an incision in the tympanic membrane aiding such insertion, said urging means being operable upon such insertion to retract said distal end of said shaft member from the myringotomy tube.
Claim 3
Dependent Claim
87 words
The myringotomy tube inserter according to claim 1, wherein said means for urging includes a second handle slidably engaging said shaft member adjacent said enlarged head portion and movable relative to said first handle and thus to said sleeve member, such that when said second handle moves relative to said first handle, said second handle engages said enlarged head portion to move said shaft member longitudinally with respect to said sleeve member, causing said distal end of said shaft member to be retracted into said sleeve member.
Claim 4
Dependent Claim
22 words
The myringotomy tube inserter according to claim 2, wherein each of said first and second handles is provided with a finger loop.
Claim 5
Dependent Claim
86 words
A method for inserting a myringotomy tube in an ear drum, comprising the steps of making an incision in the tympanic membrane of an ear, inserting a myringotomy tube in the incision with the myringotomy tube inserter of claim 1, rotating the enlarged head portion on the shaft member of the myringotomy tube inserter to twist the myringotomy tube into the incision, and operating the urging means to withdraw the shaft member distal end within the sleeve member, releasing the myringotomy tube from the shaft member.
