The device is 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 a cannula for receiving the depth finding placeholder and an adjustable depth of insertion element, wherein the adjustable depth of insertion element is adjusted to determine the appropriate tissue depth. The depth finding placeholder may include but is not limited to a wire, such as a K-wire for example. The cannula preferably comprises an opening of sufficient diameter to permit insertion of the depth finding placeholder. The cannula optionally comprises depth indicators, for example by being optionally marked with depth indicator markings. The device preferably comprises a transparent window, or optionally may comprise, additionally or alternatively, an open aperture and/or a viewing screen, to enable the depth indicators to be viewed. ## Claims ### Claim 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. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 1) 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. ### Claim 4 (depends on 1) The device of claim 1, wherein a diameter of said elongated shaft does not exceed a diameter of the implant. ### Claim 5 (depends on 1) 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. ### Claim 6 (depends on 1) The device of claim 1, wherein the implant is cannulated. ### Claim 7 (depends on 6) The device of claim 6, wherein the implant is a cannulated nail, pin, wire or screw. ### Claim 8 (depends on 1) 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. ### Claim 9 (depends on 1) 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. ### Claim 10 (depends on 1) The device of claim 1, wherein the device comprises carbon fiber composite or a metal. ### Claim 11 (depends on 10) The device of claim 10, wherein the metal is stainless steel, titanium, or an alloy or composite thereof. ### Claim 12 (depends on 1) 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. ### Claim 13 (depends on 12) The system of claim 12, wherein the depth finding placeholder comprises a wire. ### Claim 14 (depends on 13) The system of claim 13, wherein said wire comprises a K-wire. ### Claim 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. ### Claim 16 (depends on 15) 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. ### Claim 17 (depends on 15) 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. ### Claim 18 (depends on 15) 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. ### Claim 19 (depends on 15) 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. ### Claim 20 (depends on 15) 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.
