Abstract
In accordance with at least one aspect of this disclosure, a surgical rod cutter assembly includes a first blade member including a first open notch in a first end thereof. The first open notch spans across a first ingress axis, along which a rod is inserted for cutting. A first rotation bore is defined through the first blade member, a linkage of the first blade member extends away from the rotation bore on a first linkage axis, and the first rotation bore intersects the first linkage axis.
Claims20
A surgical rod cutter assembly comprising:
- a first blade member including a first open notch in a first end thereof, wherein the first open notch spans across a first ingress axis, wherein there is a first rotation bore defined through the first blade member, wherein a linkage of the first blade member extends away from the rotation bore on a longitudinal axis of the first linkage, and wherein the first rotation bore intersects the longitudinal axis of the first linkage;
- a second blade member including a second open notch in a first end thereof, wherein the second open notch spans across a second ingress axis, wherein there is a second rotation bore defined through the second blade member, wherein a linkage of the second blade member extends away from the second rotation bore on a longitudinal axis of the second linkage, and wherein the second rotation bore intersects the longitudinal axis of the second linkage;
- and
- a fulcrum pin engaged through the first and second rotation bores to rotationally engage the first and second blade members together wherein:
- in an open position, the first and second ingress axes are aligned with one another to admit a rod therealong into the first and second open notches for cutting, and the first and second linkage axes are angled to a narrow position relative to one another and wherein:
- in a closed position, the first and second ingress axes are angled relative to one another, and, the first and second linkage axes are angled at a widened position relative to the narrow position,
- wherein the first blade member includes a first pawl extending into a pocket of the second blade member, wherein in the closed position, the first pawl cooperates with the terminal surface of the second open notch to form a capture pocket configured to capture a cut rod piece after cutting the rod.

A kit comprising:
- a package having a sterile interior enclosing:
- a first blade member including a first open notch in a first end thereof, wherein the first open notch spans across a first ingress axis, wherein there is a first rotation bore defined through the first blade member, wherein a linkage of the first blade member extends away from the rotation bore on a longitudinal axis of the first linkage, and wherein the first rotation bore intersects the longitudinal axis of the first linkage;
- a second blade member including a second open notch in a first end thereof, wherein the second open notch spans across a second ingress axis, wherein there is a second rotation bore defined through the second blade member, wherein a linkage of the second blade member extends away from the second rotation bore on a longitudinal axis of the second linkage, and wherein the second rotation bore intersects the longitudinal axis of the second linkage;
- and
- a fulcrum pin configured to be engaged through the first and second rotation bores to rotationally engage the first and second blade members together wherein:
- in an open position, the first and second ingress axes are aligned with one another to admit a rod therealong into the first and second open notches for cutting, wherein the first and second linkage axes are angled to a narrow position relative to one another in the open position, and wherein:
- in a closed position, the first and second ingress axes are angled relative to one another, and wherein in the closed position, the first and second linkage axes are angled at a widened position relative to the narrow position,
- wherein the first blade member includes a first pawl extending into a pocket of the second blade member, wherein in the closed position, the first pawl cooperates with the terminal surface of the second open notch to form a capture pocket configured to capture a cut rod piece after cutting the rod.
