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. Such as 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 durin...

Abstract

The invention discloses a lumbar puncture virtual simulation and training system supporting force-sense interaction, which includes a computing device and a force-sense interaction device, and a display device is connected to the computing device; wherein, the computing device is connected to the force-sense interaction device, It is used to transmit the action signal made by the user detected by the force-sense interaction device to the computing device, and the computing device will bring the received signal into the preset model for real-time simulation calculation, and obtain the force of the puncture needle and transmit it to the force-sense interaction device It is perceived by the user, and at the same time, a real-time virtual puncture process interface is generated on the display device according to the simulation calculation results, thereby realizing virtual simulation and training of lumbar puncture. This system can simulate the change of resistance during the puncture process, which can greatly reduce the cost and cycle of training medical personnel.

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...
