Abstract

A device, system and method for delivery of an implant having an adjustable length. 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.

Core Innovation

The invention relates to a device for inserting an implant at an appropriate tissue depth according to a depth finding placeholder. The device includes an elongated shaft comprising a cannula for receiving the depth finding placeholder and an adjustable depth of insertion element comprising a dial knob. Rotation of the dial knob exposes or covers the elongated shaft at a proximal end of the device, and the extent of exposure of the elongated shaft determines the implant insertion depth relative to a tissue surface.

The implant insertion device also includes an adjustable depth of insertion element surrounding the elongated shaft. Rotation of the 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. This adjustable positioning is configured so that the extent of exposure determines the appropriate implant insertion depth relative to a tissue surface.

At the distal end, the implant insertion device includes a measuring portion comprising a recess and a measuring scale. The measuring portion is configured to provide measurement based on the depth finding placeholder and to support determining the appropriate implant insertion depth relative to a tissue surface.

Claims Coverage

The independent claims are 2 in total. The inventive coverage centers on a cannulated elongated shaft, an adjustable depth of insertion element actuated by a dial knob to expose or cover the shaft at a proximal end for determining insertion depth relative to a tissue surface, and a distal measuring portion with a recess and a measuring scale.

Across the independent claims, the key inventive concept is controlling implant insertion depth relative to a tissue surface by using a depth finding placeholder with a cannulated elongated shaft and a dial knob that exposes or covers a portion of the shaft at the proximal end. The second independent claim additionally requires a distal measuring portion comprising a recess and a measuring scale.
