Abstract
A three-dimensional radiological image of a living being is acquired and an anatomical feature of interest therein is identified. A three-dimensional print of the feature is created; the print has haptic characteristics that are similar to those of the anatomical feature of interest. The print is incorporated into a model upon which a medical student can simulate a surgical operation. A simulator is provided; the simulator simulates the operation of a c-arm fluoroscope. This enables the medical student to simulate surgery while operating a fluoroscope.
Claims16
A surgery simulation system, comprising:
- a. a three-dimensional model of an actual anatomical structure of a living being;
- b. a three-dimensional imitation of an actual surgical instrument of a type that is suitable for performing surgery on the actual structure;
- c. a fluoroscope simulator in which a three-dimensional radiological image of the structure is stored or computed, the simulator having
- i. first means for registering the spatial location and orientation of the model;
- ii. second means for registering the spatial location and orientation of the imitation instrument;
- iii. controls simulating the operating characteristics and configuration of a fluoroscope;
- and
- iv. a display for displaying a simulated fluoroscopic image corresponding to the spatial locations and positions of the model and the imitation instrument and the simulated fluoroscope operating characteristics and configuration.
A surgery simulation system, comprising:
- a. a three-dimensional model of a region of an actual human being, the model comprising a plurality of three-dimensional submodels of anatomical structures, each of said plurality corresponding to an actual anatomical structure of the human being located in the region;
- b. a three-dimensional imitation of an actual surgical instrument of a type that is suitable for performing surgery in the region;
- c. a fluoroscope simulator in which a three-dimensional radiological image of the region and submodels therein are stored or computed, the simulator having
- i. first means for registering the spatial location and orientation of the region and individually registering the spatial location and orientation of each of the submodels therein;
- ii. second means for registering the spatial location and orientation of the imitation instrument;
- iii. controls simulating the operating characteristics and configuration of a fluoroscope;
- and
- iv. a display for displaying a simulated fluoroscopic image corresponding to the spatial locations and positions of the region and the submodels therein and the imitation instrument and the simulated fluoroscope operating characteristics and configuration.
A method of teaching a student to perform a surgical operation, comprising the following steps:
- a. providing the student with a first physical model of a first body type;
- b. requiring the student to perform a simulated surgical operation on the first model;
- c. providing the student with a second physical model of a second body type;
- and
- d. requiring the student to perform the same simulated surgical operation on the second model.
A method of teaching a medical student to perform a surgical operation on a human being, the operation being of a type that is conventionally performed using a fluoroscope, comprising:
- a. providing the student with a model upon which the student can perform a simulation of the surgical operation, the model containing a three-dimensional print of a three-dimensional radiological image of an anatomical structure of interest of a human being and the print having haptic characteristics similar to those of the structure of interest;
- b. providing the student with a three-dimensional imitation of an actual surgical instrument of a type that is suitable for performing the surgical operation;
- c. providing the student with a fluoroscope simulator in which the three-dimensional radiological image is stored or computed, the simulator having
- i. first means for registering the spatial locations and orientations of the model and the print,
- ii. second means for registering the spatial location and orientation of the imitation instrument,
- iii. controls simulating the operating characteristics and configuration of a fluoroscope, and
- iv. a display for displaying a simulated fluoroscopic image corresponding to the spatial locations and positions of the region and the submodels therein and the imitation instrument and the simulated fluoroscope operating characteristics and configuration;
- d. requiring the student to perform a simulation of the operation on the model using the imitation surgical instrument while operating the controls;
- e. registering movement of the imitation instrument and operation of the controls during performance of the simulation of the operation;
- and
- f. using the duration of the simulated operation and the simulated dose delivered during performance of the simulation of the operation to derive a measurement of the student's proficiency in performing a simulation of the surgical operation.
A method of constructing a model upon which a student can perform a simulated surgical operation, comprising:
- a. acquiring a three-dimensional radiological image of a region of a living being;
- b. identifying, in said image, an anatomical structure of interest;
- and
- c. creating, from said image, a three-dimensional print of the structure of interest, the print having haptic characteristics similar to those of the structure of interest.
