Selective compression and distraction instrument

A selective compressor and distractor instrument comprising:

• a three-piece collection of pivotal members distinct from each other in construction,
• one of said members being a jaw member having a work-piece end and a force-receptive end,
• the other two of said members being handle members with each thereof having a pivot axis and hand-grippable portions located to a first side of said pivot axis and jaw member connectable portions located to a second side of said pivot axis opposite from said first side,
• said jaw member connectable portions on a first one of said handle members being disposed relative to said pivot axis and said hand grippable portions to move toward each other in response to moving said handle grippable portions of said first handle member toward each other, and said jaw member connectable portions on a second one of said handle members being disposed relative to said pivot axis and said hand grippable portions to move away from each other in response to moving said handle grippable portions of said second handle member toward each other, and
• a releasable connection interengaged between said jaw member and said jaw member force-receptive end connectable portions and said connection being arranged to accommodate releasable attachment of a selected one of said handle members with said jaw member for selective compression and distraction.

A selective compressor and distractor instrument comprising:

• a kit having two handles and one jaw pivotal assembly selectively releasably attached to either of said handles,
• said jaw pivotal assembly having two work-piece engaging surfaces facing each other and having two work-piece engaging surfaces facing away from each other and with the respective two of said surfaces being movable toward and away from each other upon pivot action of said assembly,
• each of said two handles having two elongated members pivoted together about a pivot axis and having two grippable portions squeezable toward each other, and
• each two of said elongated members having two jaw portions movable in response to squeezing of said two grippable portions toward each other and with said jaw portions being disposed relative to said pivot axis to have said two jaw portions on a first one of said handles move toward each other for compression of a work-piece by said jaw pivotal assembly surfaces in response to the squeezing and to have said two jaw portions on a second one of said handles move away from each other for distraction of a work-piece by said jaw pivotal assembly in response to the squeezing.

A compressor and distractor instrument kit comprising:

• a three-piece kit including two handles and one jaw member,
• each of said handles having two handle-squeezable portions and two jaw portions which respectively move toward and away from each other in response to squeezing of said handle-squeezable portions,
• said two handles having constructions different from each other and being arranged whereupon squeezing said handle-squeezable portions of one of said handles causes the respective said jaw portions to move towards each other and squeezing said handle-squeezable portions of the other of said handles causes the respective said law portions to move away from each other, and
• said jaw member and each said two handles having releasable interconnectors selectably and alternately engageable between said handles and said jaw member.

A compressor and distractor instrument kit for forcing on bone in surgical operations comprising:

• a pivotal handle section being squeezable to a pivoted closed position and being spring-biased to a pivoted open position and having a jaw portion with two connection areas with each thereof having an axis extending therethrough and with each thereof being arranged for pivotal open and closed movement of said connection areas selectively toward and away from each other upon alternate squeezing and releasing of said handle section,
• two jaw tips releasably connected to respective ones of said connection areas and extending along each respective axis thereof and being movable toward and away from each other in response to the pivotal movement of said connection areas and having blades thereon for contacting bone for applying force to the bone,
• the releasable connection between said jaw tips and said connection areas being a telescopic connection with said tips being movable along said axis for connecting and disconnecting said tips relative to said connection areas, and
• said telescopic connection has identical flat-sided surfaces on said jaw tips and said jaw portion and with said surfaces being in contact with each other and extending parallel to the extent of said axis and being arranged to preclude rotation of said jaw tips relative to said jaw portion.

A method of selectively effecting an instrument for use in forcing on bone, comprising the steps of:

• pivotally assembling a work piece jaw having two spaced-apart ends disposed extending in respective two planes which are parallel to each other,
• arranging said jaw for movement of said ends toward and away relative to each other and only in the parallel relationship throughout the movement,
• applying a handle to said jaw for effecting the movement of said ends, and
• providing a jaw tip arranged to be releasably attachable to each respective one of said ends for contact of the bone for forcing onto the bone.
