Abstract
In an illustrative embodiment, an apparatus includes a first rod formed from a first material and a second rod formed from a second material. The first rod includes a first end defining a cavity exposed at an end of the first rod. The cavity has a cavity length and a cavity width perpendicular to a longitudinal axis of the first rod. The cavity length is greater than the cavity width. The second rod includes a first section and a second section. The first section has a width that corresponds to the cavity width and a length that corresponds to the cavity length. The apparatus includes a bonding structure that attaches the first rod to the second rod.
Claims17
An apparatus comprising:
- a first rod formed from a first material, the first rod including a first end configured to define a cavity exposed at an end of the first rod, the cavity having a cavity length and a cavity width perpendicular to a longitudinal axis of the first rod, the cavity length being greater than the cavity width;
- a second rod formed from a second material, the second rod including a first section and a second section, the first section having a flattened end in a paddle shape including a paddle width that corresponds to the cavity width, a paddle thickness, and a length that corresponds to the cavity length, the second section having a cross-sectional dimension that is less than the paddle width and greater than the paddle thickness;
- and
- a bonding structure configured to attach the first rod to the second rod.
A medical system comprising:
- a handle;
- a first rod couplable to the handle, the first rod formed from a first material, the first rod configured to define a cavity exposed at an end of the first rod, the cavity having a cavity length and a cavity width perpendicular to a longitudinal axis of the first rod, the cavity length being greater than the cavity width;
- a second rod formed from a second material, the second rod including a first section and a second section, the first section having a flattened end in a paddle shape including a paddle width that corresponds to the cavity width, a paddle thickness, and a length that corresponds to the cavity length, the second section having a cross-sectional dimension that is less than the paddle width and greater than the paddle thickness;
- and
- a bonding structure configured to attach the first rod to the second rod.
An apparatus comprising:
- a first rod formed from a first material, the first rod including a first end configured to define an oblong cavity exposed at an end of the first rod;
- a second rod formed from a second material, the second rod including a paddle section and a second section including a circular cross-sectional shape with a first diameter, the paddle section having a width greater than the first diameter, a thickness less than the first diameter, and a length;
- and
- a bonding structure configured to attach the first rod to the second rod,
- wherein the oblong cavity is dimensioned to receive the paddle section of the second rod and includes at least one dimension perpendicular to a longitudinal axis of the first rod smaller than the first diameter.
