Abstract
The present application is directed to devices and methods for cutting a spinal implant. In one embodiment, the device includes a handle and a head. The handle is sized to receive a predetermined length of the implant. A head is rotatably attached to the handle and includes a blade. After the implant is inserted into the handle, the head is rotated causing the blade to move around the implant and cut an excessive length from the predetermined length.
Claims20
A device to cut an elongated spinal implant comprising:
- a handle including an elongated receptacle that extends along a longitudinal axis and is sized to receive the implant, the receptacle including an open front end, a back member, and an intermediate side that extends between the open front end and the back member, the longitudinal axis extends through the open front end and the back member;
- a blade rotatably attached to the handle at the open front end and being adjustable in a radial direction relative to the longitudinal axis;
- the receptacle sized to receive the implant through the open front end with a length of the implant within the receptacle and an excess length extending outward beyond the blade;
- and
- rotation of the blade relative to the handle causes the blade to move around the implant and cut the excess length of the implant.
A device to cut an elongated spinal implant comprising:
- a frame comprising an interior space formed by first and second annular members and a plurality of longitudinal members attached to and extending between the annular members, the longitudinal members spaced around perimeters of the first and second annular members, wherein a longitudinal axis extends along the longitudinal members and through openings associated with the first and second annular members;
- and
- a blade rotatably attached to the first annular member, the blade being adjustable in a radial direction relative to the longitudinal axis;
- wherein rotation of the blade relative to the frame moves the blade to cut the implant into a first portion disposed in the interior space and a second portion extending outwardly from the interior space beyond the blade.
A device to cut an elongated spinal implant comprising:
- a handle comprising an elongated receptacle with an open end and a back spaced from the open end, the receptacle being sized to receive the implant and includes a longitudinal axis that extends through the open end and the back;
- a depth limiter secured to the back and movable within the receptacle along the longitudinal axis;
- a blade operatively connected to the handle and being adjustable in a radial direction relative to the longitudinal axis;
- the implant insertable through the opening and the open end and into the receptacle with the implant in contact with the depth limiter to position a predetermined length of the implant within the receptacle with an excess length extending outward beyond the blade;
- wherein rotation of the blade relative to the handle causes the blade to move around the implant and cut the excess length of the implant from the predetermined length.
