Abstract

Abstract A distractor for separating adjacent elements, such as vertebrae. The distractor preferably has a scissors-type distracting mechanism, either in a simple scissors or double-acting scissors configuration. The distractor includes blades that are removable from the jaws of the distractor such that different blades may be used depending on the patient and situation with which the distractor is to be used. The jaws include a mating fixture and the blades include a mating portion for removable association with the mating fixture.

Claim 16
Dependent Claim 120 words
A distractor comprising: first and second handles defining a first longitudinal axis; first and second jaws respectively associated with said first and second handles; and a distractor mechanism coupled between said bandies and said jaws such that movement of said handles actuates said disfractor mechanism to move said jaws apart alone a second axis substantially perpendicular to the first longitudinal axis; wherein at least one of the first and second handles includes a mating fixture defining a third axis substantially perpendicular to a nine defined by the first and second axes, and at least one of said first and second jaws is formed with a mating portion configured for removable association with said mating fixture substantially along the third axis.
Claim 17
Dependent Claim 120 words
A distractor comprising: first and second handles defining a first longitudinal axis; first and second jaws respectively associated with said first and second handles; and a distractor mechanism coupled between said bandies and said jaws such that movement of said handles actuates said disfractor mechanism to move said jaws apart alone a second axis substantially perpendicular to the first longitudinal axis; wherein at least one of the first and second handles includes a mating fixture defining a third axis substantially perpendicular to a nine defined by the first and second axes, and at least one of said first and second jaws is formed with a mating portion configured for removable association with said mating fixture substantially along the third axis.
