VIRTUAL SURGERY
INTRODUCTION
Rapid change is under way on several fronts in medicine and surgery. The ideal learning opportunities afforded by simulated and virtual environments have prompted their exploration as learning modalities for surgical education and training. Ongoing improvements in this technology suggest an important future role for virtual reality and simulation in medicine.
What is Virtual Surgery?
Virtual surgery, is a Virtual Reality Technique of simulating surgery procedure on 3D models. If the surgeon finds some errors, he can correct by practicing it number of times.
Virtual reality in surgery
Training and education
Surgical planning
Image guidance
Tele-surgery
Training and education
VR simulators and models allow users to view the anatomy from a wide range of angles and perform a procedure countless times.
3D reconstruction has proven particularly useful in planning stereostatic and minimally invasive neurosurgical procedures. Modeling of deformable facial tissues has enabled simulations of tissue changes and the postoperative outcome of craniofacial surgery.
Traditional Vs Virtual
Training in Virtual Reality in different angles….
Surgical Planning
In traditional surgery planning, the surgeon calculates various parameters and procedure for surgery from his earlier experience and imagination.
The incorporation of the virtual reality techniques helps in reducing the errors.
Basic research in image processing and segmentation of computed tomography and magnetic resonance scans has enabled reliable 3D reconstruction of important anatomical structures
Helps to understand complex anatomical relationships in specific patient and also to examine and display the microsurgical anatomy of various internal operations.
Image guidance
. Navigation in surgery relates on stereotatic principles, based on the ability to locate a given point using geometric reference. Most of the work done in this field has been within neurosurgery. It also proved useful in Robotic Surgery, a new technique in which surgeon remotely manipulate robotic tool inside the patient body.
This has been used in conjunction with an open MRI scan to allow precise, updated views of deformable brain tissues.
Tele Surgery
The surgeon relies on a 3D virtual representation of the patient and benefit from dexterity enhancement afforded by the robotic apparatus’ prototype tele manipulator has been used to successfully perform basic vascular and urologic procedures in swine’s.
Tele-surgery allows surgeons to operate on people who are physically separated from themselves
Conclusion
Medical virtual reality has come a long way in the past 10 years as a result of advances in computer imaging, software, hardware and display devices.
Despite few concerns, the benefits of VR systems in medicines have clearly been established in several areas, including improved training, better access to services, and increase cost effectiveness and accuracy in performing certain conventional surgical procedures.
