Minimally invasive surgery simulation device based on magnetic damper

Abstract

The invention discloses a minimally invasive operation simulation apparatus based on magnetic dampers. The apparatus is characterized in that a two-dimensional rotary vertical shafting, which is formed by a pitch shaft and a course shaft, of a main frame plate is arranged; the main frame plate is provided with a probe rod seat, a probe rod positioned in the probe rod seat can axially move, and the probe rod is engaged with a gear through a tooth bar; the steering of bevel gears and a probe rod axial force feedback system achieve transmission, and the probe rod axial force feedback system is internally provided with the magnetic dampers; and a tail segment of the probe rod is connected with an operation clamp. The minimally invasive operation simulation apparatus provided by the invention is used for simulating the real damping effect of operation apparatuses such as a clamp touching organs such as a liver and a kidney, and can effectively help doctors to carry out simulation training of minimally invasive operations.

Description

technical field [0001] The invention relates to a minimally invasive surgery simulation training device, more specifically a minimally invasive surgery simulation device used for simulated training of minimally invasive surgery. [0002] Background technique: [0003] Minimally invasive surgery has the remarkable characteristics of small trauma, light pain, less bleeding, and quick recovery, and the concept of caring for the patient to the greatest extent and relieving the pain of the patient has attracted more and more attention. With the improvement of manufacturing precision of laparoscope, thoracoscope, hysteroscope and other endoscopes and various surgical tools, computer-based visual image processing and real-time monitoring technology continue to develop, and minimally invasive surgery technology is becoming more and more mature. Surgery is more widely used in general surgery, urology, orthopedics, facial features, and gynecology. [0004] Compared with traditional su...

AI Technical Summary

Problems solved by technology

At present, there are very few commercialized surgical simulation training systems on the market. The very few prototypes that have been developed are more realistic and vivid in operating 3D images, real-time communication of sensor data acquisition, and computer vision. That is, the force feedback is not realistic enough, and the force feedback effect of the damping methods such as motor, steel wire and spring is too different from the real situation.
