CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
The present application claims priority from Indian Patent Application Number 201711004815 dated 18th January 2018, the entirety of which is incorporated herein by a reference.
TECHNICAL FIELD
The present disclosure relates to a surgical simulator system, and more particularly, to a system and method for training and assessing medical doctors on various surgical procedures.
BACKGROUND
Simulation is an imitation of the operation of a real-world process or system over time. The act of simulating something first requires that a model be developed, this model represents the key characteristics, behaviors and functions of the selected physical or abstract system or process. The model represents the system itself, whereas the simulation represents the operation of the system over time.
These days, the biggest challenge in healthcare is the fact that there is an explosion of scientific knowledge, but this knowledge is not put to better use due to the lack of innovative technologies. The doctors and surgeons these days face limitations to channelize their expertise and skills to their full potential. The conventional method of surgical training involves the junior doctor assisting the senior doctor in the surgeries real time, observing the full surgery and the senior doctor gives his comments and tips while performing the surgery. Apart from this, the other methods used for surgical training are wooden bench-top models, live animals and human cadavers. All these methods are very generic. It cannot cover the vast array of all the different kinds of medical procedures. There is no case specific medium of surgical training for every kind of case. Due to this, the doctors are not skilled enough to handle adverse complicated cases. Also, there is no set protocol established currently to evaluate the surgical skills of these doctors.
In the present technologies, a high fidelity simulation system is developed for the human ovum collection procedure in the context of assisted human reproduction. The simulator includes a haptic feedback system and a virtual echo-graphic monitor. The main technical features of the system include the Simulation of the deformation imposed by the needle on the soft tissues, Simulation of the deformation imposed by the needle on the soft tissues and scenarios based on real clinical images. Another technology that has been developed in medical simulators offer clinicians the most realistic hands-on experience in medical training using surgical simulators to perform Minimally Invasive Surgery (MIS) and interventional procedures, at no patient risk. This technology provides surgeons, interventionists, nurses and technicians with a robust platform to learn and master critical skills to ensure procedural efficiency and promote quality outcomes. The systems offer a range of basic and advanced procedures and incorporate detailed and complete metrics for skill assessment. The user is free to practice skills and perform procedures until the required proficiency is attained. In addition, difficult and uncommon procedures may be practiced at any time. In another simulator system the surgeon performs a set of five exercises that helps him gain the required skills. Training exercises have been developed after extensive discussions with expert laparoscopic surgeons and by observing the actual operations at the hospitals. After the training, trainees’ performance is evaluated based on three parameters, viz., economy of distance, economy of time, and the negative scores (penalty) during the training of a particular exercise. While each of the systems have certain pros however, neither of the systems provide extensive assessment of the trainees’ performance.
Thus, there is a long standing need of a surgical simulator system and method thereof which enables tracking performance of the trainee, reducing errors while performance and providing quality patient care.

The basic version of the surgical simulator provides an immersive environment to the practicing doctors.
Referring to figure 1, a surgical simulator system 100, is illustrated in accordance with the present subject matter. The surgical simulator system 100 is a simulator that simulates, or models, a surgical environment. The surgical simulator system 100 helps training of medical doctors on various medical procedures virtually. Said system 100 may support both virtual and mannequin based implementation, with and without a haptic input. The surgical simulator system 100 uses the custom procedure workflow model to track the motion of model surgical equipment. The surgical simulator system 100 comprises a hardware unit 126 further comprising of a base firmware board 112, voice coil 112, an Optical Guide 113 and Magnetic Probe 114, one or more haptic device 111, a controller 110 and such like. The surgical simulator system 100 may further comprise scene and GUI sliders 109, GPU accelerator 109, animator component and transform 108, holo lens 118, robotic arm input controller 107, an application interface 106, a device layer 105, a hand pose detection 103, a virtual object 104, a Head Mounted Display / Tracker 102, and a virtual reality device 101.
In one embodiment, the surgical simulator system 100 may receive input from following devices:
• Input devices are Hand Probe, clean probe, position probe.
• An IR monitor device used to detect position of these probes and hand movements
• Camera (for observing the user’s gestures)
• Scan simulators (to track movement of surgical equipment model)
• The haptics device that models the surgical equipment themselves
• Virtual reality glasses with or without a camera
Although the present subject matter is explained considering that the system 100 is implemented as a simulator, it requires special custom hardware to function and may not work on normal computers.
In one embodiment, a custom software and data bases 205 shown in figure 2, loads one or more models into the surgical simulator system 100 upon users request and prepares all the peripherals. The system 100 is configured to prepare the scene and the sliding images using the scene manager 109 and GUI slider manager 109 respectively. The scene manager 109 manages the scene and GUI slider manager 109 manages sliding images. Animator and Transform components elements 108 manage the animation and transformation of the moving objects in the scene.
In one embodiment, hand probe, clean probe, position probe receives inputs from a user 125 and an IR monitor device detects relative position 117 of these probes/ input devices 101 and hand movements 103 of the user 125.
An application interface 106 transforms input signals from device layer 105 to the hardware unit 126. In one embodiment, the Application interface 106 comprises a game object 124 as an is internal 3D code development to detect movements and relative position 117 of the probe inside the object, wherein the object may be human organ. The game object 124 may be developed of rigid body 119, collider 120, mesh render 121 and particle system 122. The game objects 124 represent characters, props and scenery. They act as containers for Components, which implement the real functionality. For instance, a Light object is created by attaching a Light component to a game object 124. Rigid bodies 119 are software components which allow the Game Objects 124 to act under the control of physics. The Rigid body 119 can accept forces and torque to make the objects move in a realistic way. Any Game Object 124 must contain a rigid body to be influenced by gravity, act under added forces via scripting, or interact with other objects. Collider 120 defines the shape of an object for the purposes of physical collisions. A collider, which is invisible, need not be the exact same shape as the object’s mesh and in fact, a rough approximation is often more efficient and indistinguishable in gameplay.
