Surgical implant system and method

A surgical implant system comprising:

• a tissue dilator including an inner surface that defines an axial passageway and at least one first locking surface that is transversely movable relative to the inner surface;
• a tap configured for disposal within the passageway and extending between a first end configured to form a bore in tissue and a second end including an emitter configured to generate a signal representative of a position of the tap, the tap including a second locking surface;
• a collar engageable with the at least one first locking surface;
• and
• a tracking device including a sensor that receives the signal and communicates with a processor to generate data for display of an image from a monitor, the image representing position of the tap relative to a body,
• wherein the collar is configured to slidably translate along the first member to move the members between a locking orientation such that the locking surfaces are engaged to resist axial translation of the tap relative to the dilator and a non-locking orientation such that the locking surfaces are disengaged and the tap is axially translatable relative to the dilator, the members being biased to the locking orientation by a spring,
• wherein the first locking surface includes a pair of inserts movably positioned in slots in the tissue dilator, each of the inserts being connected to a screw, the collar comprising a pair of apertures, the screws each being positioned in one of the apertures, the screws being configured to translate along the apertures to move the inserts in and out of engagement with the second locking surface.

A surgical instrument comprising:

• a first member including a cavity and a pair of inserts movably positioned in slots in the first member, each of the inserts being connected to a screw;
• and
• a second member configured for disposal within the cavity and extending between a first end configured to penetrate tissue and a second end including a groove;
• a collar comprising a pair of apertures, the screws each being positioned in one of the apertures;
• and
• a spring configured to bias the members to a locking orientation,
• wherein the collar is configured to slidably translate along the first member to translate the screws along the apertures to move the inserts in and out of engagement with the groove.
