Abstract
Surgical systems and methods are disclosed for creating a 3D model of a patient's affected area using an imaging device, using the model to determine an implant orientation and position, creating patient-matched instrumentation, placing the patient-matched instrumentation on the patient's anatomy, registering a computer-assisted surgical tool, and acquiring registration information. The methods and systems also include associating the surgical tool with a computer to perform a computer assisted surgery. Also disclosed are embodiments of patient-matched instrumentation to acquire registration information.
Claims27
A patient-matched surgical guide for registering a location of a patient's bone, the surgical guide comprising:
- an inner surface that conforms to the patient's bone;
- and
- a body having a registration site that receives a registration tool of a medical device for communicating the location of that registration tool to a processor,
- wherein the registration site includes a registration point that corresponds to a reference marker described in an image of the patient's bone.
A system for registering a location of a patient's anatomic portion using a patient-matched block, the system comprising:
- a patient-matched block having an anatomy-facing surface that conforms to a patient's bone and a connector;
- and
- a mount that attaches to the bone and the connector and is configured to receive an array to communicate a location of the bone to a computer assisted surgical system.
A system for performing a computer-assisted surgical procedure for implanting a prosthetic device to a patient, the system comprising:
- a patient-matched block having a registration site and an inner surface that is configured to conform to a patient's bone;
- a surgical tool with a cutting tip that interfaces with the registration site to identify a location of the registration site;
- and
- a processor that tracks the location of the tool with respect to the location of the patient's bone.
A method of performing a computer-assisted surgical procedure for implanting a prosthetic device to a patient, the method comprising the steps of:
- creating a three-dimensional model of a portion of the patient's bone;
- determining an optimal implant or implant position;
- creating a block that conforms to the portion of the bone, the block having a registration site that corresponds to a predetermined location on the bone;
- placing the block on the patient's body;
- registering a surgical tool by touching a portion of the surgical tool to the registration site;
- defining a cutting boundary in relation to the patient's anatomy;
- and
- removing a portion of the patient's anatomy according to the cutting boundary.
A method of operating a surgical alignment guide, comprising the steps of:
- providing a patient-matched block, the block having at least one registration site and an inner surface that conforms to an anatomic portion of the patient;
- providing a surgical tool with an alignment point that interfaces with the registration site;
- and
- aligning the alignment point with respect to the at least one registration site.
A method of performing a computer-assisted surgical procedure for implanting a prosthetic device to a patient, the method comprising the steps of:
- applying a patient-matched surgical apparatus about a portion of a patient's bone, the apparatus having an inner surface that conforms to the bone portion and an alignment site that receives a registration tool;
- associating an array with the portion of the patient's bone or the registration tool;
- joining the alignment site with the registration tool;
- and
- tracking a location of the surgical tool by detecting the position of the surgical tool with respect to the array.
A system for performing a computer-assisted surgical procedure for implanting a prosthetic device to a patient, the system comprising:
- a patient-matched surgical apparatus having an inner surface that conforms to the patient's bone and an alignment site;
- a registration tool configured to interface with the alignment site to identify the location of the patient's bone;
- and
- a processor that tracks a location of a surgical tool with respect to an array.
