Abstract

A universal guide device for drilling and inserting surgical pins which comprises an elongated bar, a plurality of blocks slideable along the bar and adapted to be adjustably locked in position on the bar. Each block supports a transverse opening, the openings in the blocks being parallel to one another. In one form a removable sleeve is provided and has a complementary external configuration corresponding to the internal configuration of the opening of each block. Each sleeve has an opening therethrough such that when the sleeves are positioned in the openings in the blocks, the openings of the sleeves are parallel to one another. Each sleeve has a serrated end for engagement with the bone of a portion of the body for holding the sleeve in position during drilling of an opening and insertion of a surgical pin.

Claims

1. A universal guide device for drilling and inserting surgical pins which comprises

an elongated bar having a non-circular cross section,

a plurality of blocks having complementary non-circular openings therethrough,

said bar extending through said non-circular openings and being slideable longitudinally on said bar,

means for locking each said block in position on said bar,

each said block supporting a cylindrical sleeve defining a cylindrical opening having its axis extending transversely of the longitudinal axis of the non-circular openings in said block,

said blocks being mounted on said bar such that the cylindrical openings are parallel to one another to form guide openings for drilling openings in bone for insertion of surgical pins,

each said cylindrical sleeve having a serrated end for engagement with the bone of a portion of the body for holding said sleeve in position during drilling of an opening and insertion of a surgical pin.

2. The universal guide set forth in claim 1 wherein said guide has a square cross section.

3. A universal guide device for drilling and inserting surgical pins which comprises

an elongated bar having a non-circular cross section,

a plurality of blocks having complementary non-circular openings therethrough,

said bar extending through said non-circular openings and being slideable longitudinally on said bar,

means for locking each said block in position on said bar,

each said block supporting a cylinder defining a cylindrical opening having its axis extending transversely of the longitudinal axis of said bar,

said blocks being mounted on said bar such that the cylindrical openings are parallel to one another,

a removable cylindrical sleeve having a complementary external configuration corresponding to the internal configuration of the opening of each said cylinder of each block,

each said sleeve having an opening therethrough such that when the sleeves are positioned in said openings in said blocks the openings of said sleeves are parallel to one another,

each said cylindrical sleeve having a serrated end for engagement with the bone of a portion of the body for holding said sleeve in position during drilling of an opening and insertion of a surgical pin.

4. The universal guide set forth in claim 3 wherein each said sleeve includes a flange portion at the end opposite said serrated end engaging said block and limiting axial movement relative to said block in one direction.
