A medical simulation apparatus is provided, which is capable of performing a simulation by correlating a three-dimensional image with an entity model.Coordinates of measurement marks MP1, MP2, MP3 on a surface of a lower dental arch model 62 in a coordinate system defined by three reference marks MK1, MK2, MK3 are acquired before and after displacement of the lower dental arch model 62. The coordinates thus acquired are converted into coordinates in a coordinate system defined by reference marks PK1, PK2, PK3 on the basis of a relationship between the reference marks MK1, MK2, MK3 and the reference marks PK1, PK2, PK3. Then, changes in the coordinates after displacement of the lower dental arch model 62 are determined, and a region preliminarily specified in a three-dimensional image displayed on a display 5 is displaced on the basis of the coordinate changes thus determined.

Simulation systems and methods may enable medical training. A manufacturing unit may receive data from a configuration unit indicating identification and manufacturing parameters for an anatomy model. A data processing unit may receive data from the configuration unit identifying the anatomy model, and data from a calibration unit indicating a position and / or orientation of a position and orientation sensor relative to the anatomy model. The data processing unit may also receive data from the position and orientation sensor indicating a position and / or orientation of the anatomy model. The data processing unit may generate a virtual image using the data from the position and orientation sensor, the data from the calibration unit, and the data from the configuration unit. The data processing unit may render the virtual image to a display.

The invention relates to a mechanical operating platform for medical simulation training. The mechanical operating platform comprises operating arms, wherein the operating arms comprise a surgery appliance, an operating rod, a translation mechanism and a supporting frame; and the operating rod and the surgery appliance are connected into a whole, and the whole is translational relative to the supporting frame through the translation mechanism. The mechanical operating platform is characterized in that: the translation mechanism comprises a linear guide rail, a first transmission wheel and a first transmission wire; the linear guide rail passes through a top plate of the supporting frame, one end of the linear guide rail is fixedly connected with the operating rod, and the other end of thelinear guide rail is connected with one end of the first transmission wire; the other end of the first transmission wire is fixed relative to the operating rod; the first transmission wheel is arranged on a side plate, vertical to the top plate, of the supporting frame; an axis line of the first transmission wheel is vertical to the side plate; the middle part of the first transmission wire is wound on the first transmission wheel; and the first transmission wheel is tensioned. The mechanical operating platform for the medical simulation training is simple in structure, small in size, free from interference and collision during the simultaneous use of two operating arms, and applicable to simulation surgery operation.

The invention discloses an artificial eye for a medical simulator, wherein drive motors and bracket plates for a winking transmission mechanism and a pupil changing mechanism are fixed on a base. The winking drive motor drives eyelids to wink by a crank rocker transmission mechanism. The pupil drive motor is arranged on the pupil changing mechanism inside an eyeball to achieve pupil change; a pupil size position judging mechanism is connected on the pupil changing mechanism; and a pupil light sensitive mechanism is further connected inside the pupil changing mechanism. The eyeball is connected with the base by the bracket plates. The artificial eye integrates a winking function with a pupil changing function, has a simple and compact structure, and reliable transmission effects; and a control system for controlling the motor to rotate is added on the subsequent part, so as to achieve simulation effects including a function of winking according to different frequencies, and a function of changing the size of the pupil according to interferences of external factors. The artificial eye can be used as an artificial eye for the medical simulator, or an artificial eye for a human-like robot.

A virtual simulator includes a movable user object, an eddy current brake actuator, and a controller. The eddy current brake actuator includes an elongated conductor that is slidingly positioned within at least one magnet. The elongated conductor is coupled to the user object and movement of the user object causes the conductor to move through the at least one magnet which imparts a transient drag force on the conductor. The controller is electrically coupled to the user interface and to the at least one magnet. The controller monitors the velocity of the user object and controls a magnetic field of the at least one magnet to vary the drag force on the conductor in order to provide haptic feedback to a user that relates to force applied to the user object. The virtual simulator may include a display and be configured to perform a medical simulation procedure.

Systems and methods for simulating medical procedures are provided. In one example, systems and methods are provided for a neck simulator that presents realistic interactions with the neck during medical procedures, including injections, such as may be performed during a laryngeal injection.

A portable medical simulation system and method employs an artificial patient with a built-in haptic interface device, with up to four carriages for engaging different diameter catheters. A catheter stabilizer between each carriage expands and contracts in an accordion fashion as the carriages move in relation to each other, preventing the catheter from bending and bowing. A contrast display visual effect derived from a particle emitter software tool simulates the release of radiopaque dye within a simulated vasculature system for display on a monitor. A computer software based system is used for generating haptic effects on the catheter through control signals passed to each of the carriage motors controlling translation movement of the catheter and magnetic particle brakes controlling rotational movement of the catheter.
