Abstract
A surgical tool assembly is disclosed herein. The assembly includes a first guide tool portion configured to support an instrument. The first guide tool portion is configured to limit movement of the instrument relative to a patient site. A second guide tool portion is provided that is configured to receive at least one K-wire to stabilize the surgical tool assembly.
Claims15
A surgical tool assembly comprising:
- a first guide tool portion configured to support an instrument, wherein the first guide tool portion is configured to limit movement of the instrument relative to a patient site;
- and
- a second guide tool portion configured to receive at least one K-wire to stabilize the surgical tool assembly;
- wherein the first guide tool portion further comprises an instrument guide assembly configured to engage with a portion of the instrument, and
- wherein the instrument guide assembly comprises a slider that is slidably secured along a track defined by a base portion of the first guide tool portion, and a support interface configured to engage with the portion of the instrument, wherein the support interface is configured to pivot relative to the slider.

A method of installing an implant in a patient recipient site, the method comprising:
- arranging a first instrument relative to the patient recipient site to confirm initial characteristics of the patient recipient site and inserting a K-wire through the first instrument into a patient's anatomy;
- arranging a second instrument around the first instrument and removing the first instrument;
- inserting a cutting tool inside of the second instrument and into engagement with the patient recipient site, wherein the cutting tool has an outer circumferential cutting profile that is less than an outer circumferential profile of the implant, and the cutting tool is configured to remove bone debris from the patient recipient site;
- inserting a third instrument into the patient recipient site to determine characteristics of the patient recipient site after removing bone debris from the patient recipient site;
- and
- installing the implant into the patient recipient site using a fourth instrument, wherein the fourth instrument includes a rim configured to engage a peripheral sidewall of the implant.
