Orthopedic implants and tools
Orthopedic accessory tools such as multi-functional orthopedic sizing tools can include features for determination of a length and a diameter. Such features may include length markers positioned on a handle and at least one structure of increased dimension positioned on a shaft.
1. A tool for use with an orthopedic wire and an orthopedic implant selected from a plurality of orthopedic implants that vary in diameter and/or length, the surgical tool comprising:
a shaft having a distal end and a shaft passage extending therethrough;
a first implant sizing surface located on the shaft, wherein an outer dimension of the first implant sizing surface is greater than an outer diameter of the shaft and corresponds to a desired diameter of the orthopedic implant, and wherein the shaft and the first implant sizing surface are radiopaque; and
a handle having a handle passage extending therethrough and a plurality of length markers identifiable from an exterior of the handle, such that when the orthopedic wire is within the handle passage and extends out of the distal end through the shaft passage, a length marker from one of the plurality of length markers that is adjacent to a proximal end of the orthopedic wire permits identification of a desired length of the orthopedic implant.
2. The tool of claim 1 , wherein the first implant sizing surface is located exterior to the handle.
3. The tool of claim 1 , further comprising a second implant sizing surface located on the exterior of the shaft, wherein an outer dimension of the second implant sizing surface is greater than the outer dimension of the first implant sizing surface and corresponds to a desired diameter of the orthopedic implant.
4. The tool of claim 3 , wherein the first implant sizing surface is adjacent to the second implant sizing surface.
5. The tool of claim 1 , wherein the handle passage opens at a surface of the handle to form a channel in the handle, and wherein the plurality of length markers are adjacent to the channel.
6. The tool of claim 1 , wherein the handle comprises a transparent portion adjacent to the handle passage and to the plurality of length markers, such that a proximal end of the orthopedic wire located in the handle passage is visible from an exterior of the handle through the transparent portion.
7. The tool of claim 1 , wherein at least a portion of the handle is radio-translucent.
8. The tool of claim 1 , wherein the distal end of the shaft is configured with a drive surface that is configured to be accepted by a drive recess of the orthopedic implant.
9. The tool of claim 1 , wherein the first implant sizing surface is fixed onto the shaft.
10. A tool for use with an orthopedic wire and an orthopedic implant selected from a plurality of orthopedic implants varying in diameter and length, the tool comprising:
a driving shaft having a drive surface at a distal end and a shaft passage extending longitudinally through the drive surface and driving shaft, the drive surface configured to engage a drive recess of the orthopedic implant, at least a first implant sizing surface on the driving shaft having a first sizing diameter greater than a driving shaft diameter, wherein the first sizing diameter corresponds to a desired diameter the orthopedic implant, wherein the driving shaft and the at least one implant sizing surface are radiopaque; and
a handle located at a proximal end of the driving shaft, the handle including a handle passage located therein adjacent to the shaft passage, and the handle including a plurality of length markers identifiable from an exterior of the handle;
wherein when a distal segment of the orthopedic wire is within the handle passage and extends out of the distal end through the shaft passage, a length marker from the plurality of length markers that is adjacent to a proximal end of the orthopedic wire permits identification of a desired length of the orthopedic implant.
11. The tool of claim 10 , further comprising a second implant sizing surface located on the exterior of the driving shaft, where an outer dimension of the second implant sizing surface is greater than an outer dimension of the first implant sizing surface and corresponds to a desired diameter of the orthopedic implant.
12. The tool of claim 11 , wherein the first implant sizing surface is adjacent to the second implant sizing surface.
13. The tool of claim 10 , wherein the handle passage opens at a surface of the handle to form a channel in the handle, and wherein the plurality of length markers are adjacent to the channel.
14. The tool of claim 10 , wherein the handle comprises a transparent portion adjacent to the handle passage and to the plurality of length markers, such that a proximal end of the orthopedic wire located in the handle passage is visible from an exterior of the handle through the transparent portion.
15. The tool of claim 10 , wherein at least a portion of the handle is radio-translucent.
16. The tool of claim 10 , wherein the first implant sizing surface is fixed onto the driving shaft.
