Abstract
An improved method and device are provided for forming and/or maintaining a percutaneous access pathway. The device generally comprises an access pathway. The provided assembly substantially reduces the possibility of injury while accessing and/or re-accessing a body space.
Claims19
A device for at least one of bone cutting and bone drilling, comprising:
- one or more distal rotary cutting and/or drilling elements configured to penetrate a bone to enter a body cavity, the one or more distal rotary cutting and/or drilling elements including an internal cutting component having a hollow distal tip and a hollow axial pathway extending from the hollow distal tip at least partially axially through the internal cutting component,
- wherein the hollow axial pathway of the internal cutting component is configured to receive an internal core of bone during entry of the one or more distal rotary cutting and/or drilling elements into the bone, and wherein removal of the internal cutting component enables removal of the internal core of bone from the device, and
- wherein following removal of the internal cutting component, the device defines an access pathway comprising a continuous space extending from a distal end of the one or more distal rotary cutting and/or drilling elements through a proximal end of the device to enable fluid to drain from within the body cavity through the access pathway to an external environment.
A device for at least one of bone cutting and bone drilling, comprising:
- one or more distal rotary cutting and/or drilling elements configured to penetrate a bone to enter a body cavity, the one or more distal rotary cutting and/or drilling elements including:
- a stylet having a distal tip;
- a trephine needle disposed around the stylet and having a distal tip;
- and
- an internal cutting component within the stylet having a distal tip and a hollow axial pathway extending from the distal tip at least partially through the internal cutting component,
- wherein the distal tip of the stylet is biased distally of the distal tip of the trephine needle and the distal tip of the internal cutting component,
- wherein upon the distal tip of the stylet contacting a bone the distal tip of the stylet moves proximally to enable the distal tip of the trephine needle and the distal tip of the internal cutting component to drill into the bone, and
- wherein the hollow axial pathway of the internal cutting component is configured to receive an internal core of bone as the distal tip of the trephine needle and the distal tip of the internal cutting component drill into the bone and the internal cutting component is selectively removable to enable removal of the internal core of bone.
