Abstract
A device may be configured to convert an angle to a distance to assist with securing a bone fixation plate during a surgical procedure. The device may include a body. The body may include (e.g., define) an elongated first portion and/or a second portion. The elongated first portion may include at least one aperture. The at least one aperture may be configured to receive a wire and/or a screw. The second portion may include angular indicia. The device may include an arm. The arm may be rotatably coupled, for example to the body. Additionally, or alternatively, the arm may be rotatably coupled at a rotation point.
Claims20
A device used to assist in a medical procedure, the device configured to convert an angle to a distance, the device comprising:
- a body defining an elongated first portion and a second portion, wherein the elongated first portion comprises at least one aperture configured to receive a wire, and wherein the second portion comprises angular indicia;
- an arm rotatably coupled to the body at a rotation point;
- and
- a rod coupled to the arm at the rotation point, wherein the rod is configured to rotate about the rotation point with rotation of the arm, and
- wherein, when the rod is aligned to be parallel with a plane, the arm is configured to align with an angular indicia of the second portion of the body to indicate an angle, and the arm is configured to indicate a distance to the at least one aperture of the elongated first portion of the body.
A system comprising:
- a bone fixation plate;
- a distance holder device comprising:
- a guide tube that defines a hollow interior configured to receive a wire such that the wire can extend through the guide tube;
- and
- a clamping sleeve disposed around a circumference of the guide tube, wherein the clamping sleeve is configured to receive the wire and restrict motion of the wire through the guide tube when in a first configuration, and wherein the clamping sleeve is configured to allow movement of the wire through the guide tube when in a second configuration;
- and
- a device configured to convert an angle to a distance, wherein the device comprises:
- a body defining an elongated first portion and a second portion, wherein the elongated first portion comprises at least one aperture configured to receive the wire, and wherein the second portion comprises angular indicia;
- an arm rotatably coupled to the body at a rotation point;
- and
- a rod coupled to the arm at the rotation point, wherein the rod is configured to rotate about the rotation point with rotation of the arm, wherein, when the rod is aligned to be parallel with a plane, the arm is configured to align with an angular indicia of the second portion of the body to indicate an angle, and the arm is configured to indicate a distance to the at least one aperture of the elongated first portion of the body.
