Endoscope simulation device and application of endoscope simulation device in minimally invasive surgery training system

The invention discloses an endoscope simulation device and an application of the endoscope simulation device in a minimally invasive surgery training system. The endoscope simulation device is characterized in that the two-dimensional rotating vertical shaft system of a speculum main frame plate is formed by a speculum pitch shaft and a speculum course shaft; the speculum main frame plate is arranged on the two-dimensional rotating vertical shaft system, a speculum detecting rod base is arranged on the speculum main frame plate, and engaged transmission of a speculum detecting rod arranged in the speculum detecting rod base and a speculum transmission gear is realized via a gear rack; the speculum transmission gear is driven to axially rotate by axial movement of the speculum detecting rod in the speculum detecting rod base via the speculum transmission gear; the front end of the speculum detecting rod is provided with a detecting rod head, and the tail end is connected with a speculum potentiometer to act as an operation handle; and flexible damping is formed by all flexible damping positioning devices between the speculum detecting rod and the speculum detecting rod base and in the two-dimensional rotating shaft system. Hand feelings and skills of surgeons participating in training can be rapidly enhanced by the endoscope simulation device.
