Abstract

Claims (20)

1. A device for inserting an implant at an appropriate tissue depth according to a depth finding placeholder, wherein the implant is suitable for insertion to a subject, the device comprising an elongated shaft comprising a cannula for receiving the depth finding placeholder and an adjustable depth of insertion element, wherein the adjustable depth of insertion element comprises a dial knob, wherein rotation of said dial knob exposes or covers the elongated shaft at a proximal end of the device; wherein an extent of exposure of said elongated shaft determines the implant insertion depth relative to a tissue surface; and wherein the position of the adjustable depth of insertion element on the elongated shaft is adjusted to determine the appropriate implant insertion depth relative to a tissue surface.

2. The device of claim 1 , wherein complete coverage of said elongated shaft at the proximal end of the device determines the appropriate implant insertion depth such that the implant is inserted flush with a surface of the tissue.

3. The device of claim 1 , wherein a diameter of the depth of insertion element is large enough to prevent insertion of the depth of insertion element into said tissue.

4. The device of claim 1 , wherein a diameter of said elongated shaft does not exceed a diameter of the implant.

5. The device of claim 1 , further comprising a scale to measure the length of the depth finding placeholder to determine the appropriate length of the implant; a recess to measure the implant; and a flat surface to prevent the device from rolling.

6. The device of claim 1 , wherein the implant is cannulated.

7. The device of claim 6 , wherein the implant is a cannulated nail, pin, wire or screw.

8. The device of claim 1 , wherein the device is 100 mm to 300 mm, 120 mm to 200 mm, or 130 mm to 180 mm in length.

9. The device of claim 1 , wherein the device is 2 mm to 30 mm, 6 mm to 20 mm, or 8 mm to 12 mm in diameter at the distal end of the elongated shaft.

10. The device of claim 1 , wherein the device comprises carbon fiber composite or a metal.

11. The device of claim 10 , wherein the metal is stainless steel, titanium, or an alloy or composite thereof.

12. A system for determining an appropriate length of an implant, wherein the implant is suitable for insertion to a subject, the system comprising a depth finding placeholder and the device of claim 1 ; wherein the depth finding placeholder is inserted into the subject to a determine an appropriate depth for inserting the implant; wherein said cannula of said device receives the depth finding placeholder, and determines the appropriate length of the implant according to a measured length of the depth finding placeholder; and wherein said dial knob is rotated to determine exposure of said elongated shaft at a proximal end of the device, for inserting the implant at said appropriate depth.

13. The system of claim 12 , wherein the depth finding placeholder comprises a wire.

14. The system of claim 13 , wherein said wire comprises a K-wire.

15. An implant insertion device comprising an implant body with a proximal end and distal end, wherein the proximal end comprises an elongated shaft comprising a cannula and an adjustable depth of insertion element surrounding the elongated shaft, wherein the adjustable depth of insertion element comprises a dial knob, wherein rotation of said dial knob moves the adjustable length of insertion element proximally or distally along the elongated shaft exposing or covering a portion of the elongated shaft at the proximal end of the device; and wherein the distal end comprises a measuring portion comprising a recess and a measuring scale.

16. The device of claim 15 , wherein the position of the adjustable depth of insertion element on the elongated shaft is adjusted to determine an implant insertion depth in a tissue.

17. The device of claim 15 , wherein the device is 100 mm to 300 mm, 120 mm to 200 mm, or 130 mm to 180 mm in length and wherein the device is 2 mm to 30 mm, 6 mm to 20 mm, or 8 mm to 12 mm in diameter at the distal end of the elongated shaft.

18. The device of claim 15 , wherein the adjustable depth of insertion element comprises an abutment surface; and wherein the abutment surface is 1 mm to 10 mm, 2 mm to 8 mm or 3 mm to 6 mm in diameter.

19. The device of claim 15 , wherein the proximal end of the elongated shaft is 0.5 mm to 5 mm, 1 mm to 4 mm, or 2 mm to 3 mm in diameter.

20. The device of claim 15 , wherein the proximal end of the elongated shaft exposed at the proximal end of the device beyond the abutment surface of the adjustable depth of insertion element is 1 mm to 6 mm, 2 mm to 5 mm, or 3 mm 4 mm in length.
