Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
179 words
A jig for inserting an implant into an animal, the jig comprising: a first member comprising a first housing and a first leg having a first end and a second end, the second end extending vertically downward from the housing, the first leg having a plurality of openings extending therethrough along an axis perpendicular to the first leg and adapted to receive a prothesis having openings formed therethrough such that one of the openings in the prostesis is aligned with one of the opening in the first leg; an elongated shank having first and second ends, the first end attached to the first housing; and a second member comprising a second housing and a second leg having a first end and a second end, the second leg attached to the second end of the shank, the second end of the second leg extending vertically upward from the second housing and the housing having a plurality of openings extending therethrough in a direction perpendicular to the second leg and along the same axis as the openings in the first leg.
Claim 2
Dependent Claim
179 words
A jig for inserting an implant into an animal, the jig comprising: a first member comprising a first housing and a first leg having a first end and a second end, the second end extending vertically downward from the housing, the first leg having a plurality of openings extending therethrough along an axis perpendicular to the first leg and adapted to receive a prothesis having openings formed therethrough such that one of the openings in the prostesis is aligned with one of the opening in the first leg; an elongated shank having first and second ends, the first end attached to the first housing; and a second member comprising a second housing and a second leg having a first end and a second end, the second leg attached to the second end of the shank, the second end of the second leg extending vertically upward from the second housing and the housing having a plurality of openings extending therethrough in a direction perpendicular to the second leg and along the same axis as the openings in the first leg.
Claim 3
Dependent Claim
20 words
The jig as described in claim 1 wherein the openings of the legs are adapted to receive a drill bit.
Claim 4
Dependent Claim
17 words
The jig as described in claim 2 wherein the openings have a diameter of approximately 4.5 mm.
Claim 5
Dependent Claim
