Embodiment Construction

[0039] The specific implementation steps of the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0040]The present invention utilizes virtual reality technology to establish a "lumbar puncture virtual training system", aiming to provide medical students with a training mode with strong sense of reality and high reliability. like figure 1 As shown, during the puncture process, the puncture needle passes through the skin, fat, supraspinous ligament, intervertebral ligament, ligamentum flavum, and dura mater in sequence. Because the elasticity of each layer of tissue is different, when the needle tip of the puncture needle enters a certain layer of tissue, the operator will feel the increase or decrease of resistance, which is a reminder for the operator, and experienced operators can judge accordingly The position of the needle tip. The system can simulate the change of resistance during p...

Abstract

The present invention discloses a lumbar puncture virtual simulation and training system supporting haptic interaction, comprising a calculating apparatus and a haptic interaction device. A display device is connected to the calculating apparatus. The calculating apparatus is connected to the haptic interaction device, and is configured to transmit an action signal that is made by a user and is detected by the haptic interaction device to the calculating apparatus. The calculating apparatus substitutes the received signal to a preset model to perform real-time simulation calculation, to obtain an acting force of a puncture needle, and transmits the acting force to the haptic interaction device for perception of the user. In addition, a real-time virtual puncture process interface is generated on the display device according to a simulation calculation result, so as to implement lumbar puncture virtual simulation and training. The system can simulate a resistance change in a puncture process, and can significantly reduce costs and the period of medical staff training.

Description

technical field [0001] The invention designs a virtual simulation and training system for lumbar puncture, which belongs to the cross application field of virtual reality, system simulation and medical information technology. Background technique [0002] A lumbar puncture can be used both diagnostically and therapeutically. Lumbar puncture technology is also one of the difficulties in medical teaching. It requires doctors to have high surgical skills, accurate and efficient hand-eye coordination, and a lot of strict preoperative skill training and practice. The training period is extremely long and requires strong practical ability. figure 1 Shown is the anatomical schematic diagram of lumbar puncture. When the puncture needle passes through the skin, fat, supraspinous ligament, intervertebral ligament, ligamentum flavum, and dura mater in sequence, the elasticity of each layer of tissue is different, so the puncture needle is different. Different resistance, for the opera...
