Abstract
Abstract An adjustable staple to be used in bone surgery, comprising a horizontally laying U-shaped member wherein the lower arm (3) is movable parallel to itself in respect of the upper fixed arm (1), and adapted to be fastened by pressure in any position; said movement taking place by means of a dovetail joint between the jportion (5) orthogonal to the upper arm (1) and the portion (7) orthogonal to the lower arm (3); the fastening once reached the desired position being provided by two socket head screws (9), aligned and opposed, engaging corresponding seats in the portion (5) of the movable arm and acting with pressure against the portion (7) of the movable arm.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
186 words
An adjustable staple to be used in bone surgery, comprising a horizontally laying U-shaped member wherein the upper tab of the U forms the upper arm (1) of the staple, the lower tab the lower arm (3) of the same, and the connecting segment of the two tabs (i.e. the botton of the U) the portion orthogonal to the two arms, characterized in that the lower arm (3) of the staple is movable parallel to itself in respect of the upper fixed arm (1), and is adapted to be fastened by pressure in any position along said movement; said movement taking place by means of a dovetail joint between the portion (5) orthogonal to the upper arm (1) and the portion (7) orthogonal to the lower arm (3); said movement of the portions (5, 7) being manually carried out by the operator; the fastening once reached the desired position being provided by two socket head screws (9) engaging corresponding aligned and opposed threaded seats in the portion (5) of the fixed arm (1), and exerting a pressure against the portion (7) of the movable arm (3).
Claim 2
Dependent Claim
186 words
An adjustable staple to be used in bone surgery, comprising a horizontally laying U-shaped member wherein the upper tab of the U forms the upper arm (1) of the staple, the lower tab the lower arm (3) of the same, and the connecting segment of the two tabs (i.e. the botton of the U) the portion orthogonal to the two arms, characterized in that the lower arm (3) of the staple is movable parallel to itself in respect of the upper fixed arm (1), and is adapted to be fastened by pressure in any position along said movement; said movement taking place by means of a dovetail joint between the portion (5) orthogonal to the upper arm (1) and the portion (7) orthogonal to the lower arm (3); said movement of the portions (5, 7) being manually carried out by the operator; the fastening once reached the desired position being provided by two socket head screws (9) engaging corresponding aligned and opposed threaded seats in the portion (5) of the fixed arm (1), and exerting a pressure against the portion (7) of the movable arm (3).
Claim 3
Dependent Claim
53 words
An adjustable staple as claimed in claim 1, characterized in that the socket head screws (9) for fastening the movable member (3) with respect to the fixed member (1) provide for a polygonal socket, e.g. hexagonal, so as to be driven by a control rod having the same polygonal cross section, e.g. hexagonal.
Claim 4
Dependent Claim
74 words
An adjustable staple as claimed in claim 1, characterized in that the staple movable arm (3) can be fitted on the portion (5) pertaining to the fixed arm (1) in a reversed position, that is in such a way as to present the movable arm (3) in a decidedly nearer position to the parallel fixed arm (1), to allow for, as a limit, the contact between the two arms (1, 3) of the staple.
