Instruments for a variable angle approach to a joint

摘要

Instruments and associated methods are disclosed for treating joints, and particularly bone tissue. One of these instruments may be a positioning instrument for controlled delivery of a device to a target site of the bone tissue being treated. The positioning instrument may comprise a main body extending at one end into an indicator probe for visual determination of a target site of a bone to be treated, and at an opposite end into a handle. A rail extends from the main body. The instrument also includes an alignment guide having a device portal for insertion of a device therethrough, the alignment guide being detachable and movable along a length of the rail. The device may comprise an implant insertion tool, an injection catheter, a cavity creation tool such as a bone drill, for example, or the device may be an implantable device.

1. A positioning instrument for controlled delivery of a device to a target site of a bone, comprising:
a main body extending at one end into an indicator probe and at an opposite end into a handle, the indictor probe having a terminal end configured for external placement on a bone surface to assist with visual identification of the target site of the bone while preserving the bone surface; a rail extending from the main body; and an alignment guide having a device portal for insertion of a device therethrough, the alignment guide being detachable and movable along a length of the rail, the device portal defining a trajectory, wherein the device portal is configured to provide delivery of the device to the target site indicated by the indicator probe, and wherein the trajectory of the device portal does not intersect with the terminal end of the indicator probe.
