Artificial eye for medical simulator

Abstract

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.

Description

technical field [0001] The present invention relates to a kind of simulation technical field, specifically, what relate to is a kind of artificial eye of medical simulator, including the function of automatic, manual blinking and pupil size change, is a set of medical simulator design for medical simulation education. The artificial eye mechanism can also be used as an artificial eye for other humanoid robots. Background technique [0002] The medical simulation eye mechanism allows medical study researchers to present certain pathological characteristics by inputting programs to simulated patients in the study pathology room, which is convenient for students to improve their understanding and mastery of pathological characteristics. The artificial eye is the most important part of simulating the patient's face and even the head. Many pathologies are judged by examining the characteristics of the human eye, especially by observing the size of the pupil. Medical personnel can...

Problems solved by technology

The advantage of this invention is that it adopts a mechanical mechanism, which is not affected by materials and environments. The disadvantage is that the circular hole of the pupil is the free end of the blade, and the blade is simply attracted by the magnet, and the blades are relatively loose. , the simulation effect is poor

At the same time, the mechanism cannot accurately control the size of the pupil zoom and shrinkage, and the zoom range is also limited, and it cannot fully simulate the normal pupil range of 1-9mm.
