Abstract

Patient-specific systems and methods are provided for assisting in medical procedures, and can include producing patient-specific devices from computer models of a patient's anatomy, including a first patient-specific device configured to identify and allow access to a resection area in an operation location for a medical procedure; a second patient-specific device configured to refine the procedure, following use of the first patient-specific device and in some embodiments, to identify and allow access to installation locations for an implant and/or surgical hardware; and/or a third patient specific device configured to assist in confirming placement of the implant and/or surgical hardware and refining the procedure, following use of the first and second patient-specific devices. Each of these devices may be developed from patient-specific computer model data via patient-specific image data and may enhance a variety of procedures.

Claims27

Dependent claims

A method of producing one or more patient-specific devices to assist in a spinal procedure, the method comprising:

obtaining a spine surface image from image data of a spinal structure of a patient;
generating an operation image configured to represent a desired result in the spinal procedure, the desired result having at least one ideal resection portion, the operation image superimposed over at least a portion of one vertebra of the spine surface image and substantially aligned with an operation position, the operation position predetermined from the image data;
generating a first device image configured to identify and to allow access to a resection area during the spinal procedure, the first device image superimposed over at least a portion of one vertebra of the spine surface image and substantially aligned with the operation position, the first device image having a plurality of contact portions each configured to contact a respective surface of at least one or more vertebra of the spine surface image;
generating a second device image configured to measure if the resection area is substantially similar to the ideal resection portion, the second device image superimposed over at least a portion of one vertebra of the spine surface image and substantially aligned with the operation position, the second device image having at least one confirmation portion and a plurality of contact portions, the at least one confirmation portion configured to compare the resection area with the ideal resection portion, the plurality of contact portions formed to contact at least one of a plurality of contact surfaces, the plurality of contact surfaces configured to substantially align the second device image with the operation position;
and
converting at least one of a plurality of device images into control data, the plurality of device images including at least one of the first device image and the second device image, the control data configured to control operation of a machine, the machine configured to produce a patient-specific device from the control data.

3 more elements

A method of using one or more patient-specific devices to assist in a spinal procedure, the method comprising:

determining a size and a shape of an ideal tissue extraction of a spinal structure of a patient;
positioning a first personalized device adjacent to the spinal structure of the patient, the first personalized device configured to contact at least a portion of one of a plurality of vertebra surfaces of the spinal structure of the patient in a predetermined operation position, the predetermined operation position arranged to define an extraction area of the spinal structure of the patient;
removing a portion of the spinal structure of the patient corresponding to the extraction area defined by the first personalized device;
aligning a second personalized device with the extraction area, the second personalized device formed according to a size and a shape of at least a portion of the spinal structure after removal of the ideal tissue extraction portion of the spinal structure of the patient;
and
utilizing the second personalized device to determine if the portion of the spinal structure removed corresponding to the extraction area is substantially similar to the ideal tissue extraction of the spinal structure of the patient by engaging the second personalized device with a plurality of contact points, the plurality of contact points predetermined to represent the ideal tissue extraction portion superimposed over the extraction area.

3 more elements

A system of patient-specific devices, the system comprising:

a first personalized device configured to identify and to allow access to a resection area of a spine, the first personalized device having at one or more contact portions each configured to contact a respective surface of at least one or more vertebra of the spine and orientate the first personalized device such that the first personalized device identifies and allows access to an extraction area on the spinal structure of the patient and guide resection of a portion of the patient's anatomy according to a preoperatively planned resection;
and
a second personalized device configured to measure if the resection portion is substantially similar to the preoperatively planned resection portion, the second device image having at least one confirmation portion and a plurality of contact portions, the at least one confirmation portion configured to compare the resection portion with the preoperatively planned resection portion, the plurality of contact portions formed to contact at least one of a plurality of contact surfaces, the plurality of contact surfaces configured to substantially align the second personalized device with the operation position.
