Rocking apparatus for manipulating element in the eye

In combination,

• a) two elongated lever arms, each of which has a distal first zone, a second pivot zone or zones rearward of said distal first zone, and a third manual pressure receiving zone, at least one of said arms having grippinq structure protruding toward the other arm to enable gripping of an element between said first distal zones,
• b) said arms operatively coupled together rearwardly of said second zone so that said first distal zones are yieldably urged toward one another by said arms to hold the gripped element therebetween,
• c) said second pivot zone or zones configured to pivot in interengagement in response to controllable manual squeezing force exertion on said third zones, thereby to cause said first zones to relatively separate, enabling movement of said arm and structure relative to said element,
• d) said gripping structure comprising claw structure,
• e) said claw structure being at arm terminals, there also being smooth gripping protrusion surfaces on the arms, and spaced from said claws, whereby use of either said smooth gripping protrusions surfaces, or said claw structure, is enabled, for gripping of different objects,
• f) said arms being entirely and everywhere at opposite sides of an elongated plane extending between the arms,
• g) and including said element gripped between said distal first zones, and by said structure, said element being manipulable in an internal eye zone, as via a surgical incision in the corneo-scleral limbus.

Apparatus used for intraocular manipulation of an element in an internal eye zone, as via a surgical incision in the corneo-scleral limbus, which includes:

• a) two elongated lever arms, each of which has a distal first zone, a second pivot zone or zones rearward of said distal first zone, and a third manual pressure receiving zone, at least one of said arms having grippinq structure protruding toward the other arm to enable gripping of said element between said first distal zones,
• b) said arms operatively coupled together rearwardly of said second zone so that said first distal zones are yieldably urged toward one another by said arms to hold the gripped element therebetween,
• c) said second pivot zone or zones configured to pivot in interengagement in response to controllable manual squeezing force exertion on said third zones, thereby to cause said first zones to relatively separate, enabling movement of said arm and structure relative to said element,
• d) and wherein said pivot zones include
• i) primary and secondary pivot zones spaced apart along said arms,
• ii) whereby the primary pivot zone is operable in response to primary squeezing force exertion on said third zones to effect primary diverging of said arm distal first zone, and while the secondary pivot zone is inoperable,
• iii) and whereby the secondary pivot zone is operable in response to secondary and increased squeezing force exertion on said third zones to effect secondary diverging of said arm distal first zones, accompanied by relative separation of said primary pivot zone.

• d) and including guide means including a base for engaging said arms to effect controlled endwise displacement of said distal first zones relative to said base in response to controlled squeezing force exertion on said third zones, said guide means including structure connected to said base and slidably engageable with bowed sections of said arms between said pivot zones and said base, in response to controlled squeezing force exertion on said bowed sections.

A method of manipulating an element in an intraocular zone, as via a surgical incision in the corneo-scleral limbus, which includes

• a) providing two elongated lever arms, each of which has a distal first zone, a second pivot zone or zones rearward of said distal first zone, and a third manual pressure receiving zone, at least one of said arms having gripping structure protruding toward the other arm to enable gripping of said element between said first distal zones,
• b) said arms operatively coupled together rearwardly of said second zone so that said first distal zones are yieldably urged toward one another by said arms for holding the gripped element therebetween,
• c) said second pivot zone or zones configured to pivot in interengagement in response to controllable manual squeezing force exertion on said third zones,
• d) and exerting controlled squeezing force on said third zones thereby to cause said first zones to relatively separate enabling movement of said arms and structure relative to said element, allowing release of said element,
• e) and wherein said second zones are provided to include
• i) primary and secondary pivot zones spaced apart along said arms
• ii) whereby the primary pivot zone is operable in response to primary squeezing force exertion on said third zones, to effect primary diverging of said arm distal first zones, and the secondary pivot zone is then inoperable.
