Abstract
Description
[0001] A SYSTEM FOR SIMULATING SURGICAL INTERVENTIONS TECHNICAL FIELD
[0002] The present disclosure generally relates to surgical training systems. More particularly, the present disclosure relates to a system for simulating surgical interventions and a method thereof.
[0003] BACKGROUND OF THE DISCLOSURE
[0004] Generally, traditional methods are followed for training in medical field. One such traditional method is a SODOTO methodology of see one, do one and teach one, where a user needs to see a medical procedure being performed on a real patient, perform the medical procedure on the real patient, and thereafter teach the medical procedure. The SODOTO methodology has been supplemented by a series of two-dimensional (2D) static medical imaging data and cadaver dissection. The 2D static medical imaging data comprises images of tests such as X-ray, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET), Ultrasound, and the like. Additionally, training units of diverse types, such as plastic organs, are used to supplement human models for training in the medical field.
[0005] However, the traditional SODOTO methodology, often falls short in equipping the user for the diverse and dynamic environments encountered during real surgical interventions. One of the primary problems with conventional training methods is reliance on static two-dimensional (2D) medical imaging and general training units that do not adequately represent the complexities of actual surgical scenarios. For instance, one type of surgery may require incisions that can be several centimeters apart, leading to a very different workstation layout and tool manipulation compared to other type of surgical interventions, where the working space may be drastically reduced, often limited to just a few centimeters. Such variations necessitate distinct arrangements for surgical tools and equipment, which may greatly influence the effectiveness and efficiency of the training procedure. Moreover, traditional training may not address variations in patient anatomy and the specific spatial requirements of different surgical approaches. In one surgery, surgical tools might be positioned from the patient's side, whereas in another surgery, the surgical tools could enter from above or through a different orientation entirely. Accordingly, with existing training systems, there is a lack of hands-on experience in configuring workspace depending on the procedure type. Such lack of hands-on experience not only hampers skill acquisition but also increases the risk of errors during surgical interventions. Therefore, without considering variances in physiology, procedural layout, and tool arrangement, the user may struggle to adapt during real-world surgical interventions, leading to potential complications and adverse outcomes for the patients, which are not desirable.
[0006] The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the conventional mechanisms.
[0007] The drawbacks / difficulties / disadvantages / limitations of the conventional techniques explained in the background section are just for exemplary purpose and the disclosure would never limit its scope to only such limitations. A person skilled in the art would understand that this disclosure and below mentioned description may also solve other problems or overcome the other drawbacks / disadvantages of the conventional arts which are not explicitly captured above.

[0044] DETAILED DESCRIPTION
[0045] While the embodiments in the disclosure are subject to various modifications and alternative forms, specific embodiment thereof has been shown by way of example in the figures and will be described below. It should be understood, however, that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.

In other words, one or more elements in a system proceeded by “comprises ... a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or method.
[0047] Embodiments of the present disclosure disclose a system for simulating surgical interventions. The system includes a base defined with a plurality of engaging portions extending away from the base in a predefined orientation. The system includes a training unit supported on the base. The training unit is structured to simulate a portion of a surgical subject. The system includes at least a pair of haptic devices detachably connectable to the base. The pair of haptic devices is configured to selectively generate a haptic feedback. Further, the pair of haptic devices are defined with one or more arms to receive and transmit the haptic feedback. The system includes an adapter unit connectable to the one or more arms of the pair of haptic devices and engageable with a portion of the training unit. The adapter unit is structured to receive at least a portion of at least one surgical tool. The adapter unit is configured to receive and transmit force between the at least one surgical tool and the training unit.
[0048] Further, the system includes at least one first connector defined with a first predefined profile and having a first set of coupling portions complementing the plurality of engaging portions. The at least one first connector is detachably connectable between the base and one of the pair of haptic devices. Furthermore, the system includes at least one second connector defined with a second predefined profile and having a second set of coupling portions complementing the plurality of engaging portions. The at least one second connector is detachably connectable between the base and one of the pair of haptic devices. The at least one first connector, and the at least one second connector are detachably connectable to the base to position the pair of haptic devices relative to the base based on the first predefined profile and the second predefined profile. Such configuration aids to define different training layouts and orient the at least one surgical tool in different orientations relative to the training unit.

[0050] The disclosure is described in the following paragraphs with reference to Figures la to 15. In the figures, the same element or elements which have same functions are indicated by the same reference signs. One skilled in the art would appreciate that the system and the method as disclosed in the present disclosure may be used in any simulation systems including but not limiting to surgical simulation systems, other simulation systems for simulating one of welding training, carpentry, electrical PCB assembly (including soldering) and the like. The system and the method of the present disclosure may also be implemented in any simulation systems involving a tool requiring manual intervention for surgery on a training unit without deviating from the principles of the present disclosure.
[0051] Figure la is an exemplary embodiment of the present disclosure which illustrates a perspective view of a system (100) for simulating surgical interventions. In the present disclosure, the system (100) provides simulation of surgical interventions for training a user (155) on a training unit (500). Such training of the user (155) refers to training the user (155) on a single surgical intervention or various surgical interventions. Such surgical interventions may include, but are not limited to, a spine surgery, a knee replacement surgery, a bone marrow transplant, and other types of invasive interventions. The system (100) includes a base (1). In an embodiment, the base (1) may be defined by one of a rectangular profile, a square profile, and other suitable profiles structured to accommodate a training unit (500). In one implementation, the base (1) is defined with one or more legs to be mounted on floor or a surface such as but not limited to a table. The base (1) is made of metals such as but not limited to Iron, Stainless Steel and non-metals etc., to withstand forces during simulation of the surgical intervention on the training unit (500) and to support the training unit (500). The training unit (500) is supported on the base (1) as shown in Figures la and lb, and is structured to resemble a portion of the surgical subject. In an exemplary embodiment, the training unit (500) is structured to resemble a portion of a spine of the surgical subject to provide simulation of spine surgery, etc.
[0052] Further, the base (1) is defined with a plurality of engaging portions (11) extending away from the base (1) in a predefined orientation. The plurality of engaging portions (11) may be in the form of projections, slots, grooves and the like. In the illustrative embodiment, the plurality of engaging portions (11) are depicted as projections extending away from the base (1) as shown in Figure lb. The predefined orientation of plurality of engaging portions (11) correspond to different training layouts of the system (100) for accommodating different components of the system (100) in different training layouts corresponding to different surgical interventions. In the illustrative embodiment, the predefined orientation of the plurality of engaging portions (11) is depicted to be diametrically opposite to each other as shown in Figure lb. Such configuration of the plurality of engaging portions (11) aids to couple different components of the system (100) to the base (1) on both sides of the base (1) and provides modularity to switch position of the components of the system (100) relative to the base (1) to vary the training layout of the system (100) based on the training simulation required. In an embodiment, the plurality of engaging portions (11) are defined at any location along the periphery of the base (1) based on design requirements of the system (100).
[0053] Further, the system (100) includes the training unit (500) supported on the base (1) as shown in Figures la and lb, and structured to simulate a portion of the surgical subject. In an exemplary embodiment, the training unit (500) is structured to resemble a portion of a spine of the surgical subject to provide simulation of spine surgery, etc. In an embodiment, the training unit (500) may be structured to simulate one of a chest portion, a leg portion, an arm portion, a skull portion and the like and the same shall not be construed as a limitation. In an embodiment, the training unit (500) may be defined with one or more ports (501) or apertures corresponding to site of surgery, for example, one or more ports (501) [shown in Figure 4a] proximal to spine structure of the training unit (500). Such configuration of the one or more ports (501) may provide access to the region of interest within the training unit (500) to the user (155) while aligning the at least one surgical tool (200) based on the position of the one or more ports (501). The position and number of ports (501) of the training unit (500) may be varied based on type of portion of the surgical subject being simulated and the same shall not be construed as a limitation.
[0054] Referring now to Figures 1c and Id, the system (100) includes at least a pair of haptic devices (300) detachably connectable to the base (1). The pair of haptic devices (300) are configured to selectively generate a haptic feedback. The pair of haptic devices (300) are configured to generate the haptic feedback corresponding to type of surgical intervention being simulated by the system (100). For example, the haptic feedback includes resistive force corresponding to tension in a muscle of back near spine in a simulation of a spinal surgery and the like. Further, the pair of haptic devices (300) are defined with one or more arms (310) to receive and transmit the haptic feedback to the user (155). The one or more arms (310) extend toward the training unit (500) as shown in Figures 1c and Id to receive at least one surgical tool (200) and engage the at least one surgical tool (200) with a portion of the training unit (500). In an embodiment, the one or more arms (310) may include angular arms, cartesian arms and the like. In the illustrative embodiment, the one or more arms (310) are depicted as angular arms (310) for 3 dimensional movement of the at least one surgical tool (200) and the same shall not be construed as a limitation, as other 3 -dimensional arms (310) suitable for movement of the at least one surgical tool (200) may also be implemented. In an embodiment, the one or more arms (310) may include multiple links pivotally or rigidly coupled to each other to extend between the pair of haptic devices (300) and the training unit (500) and to form the connection between the training unit (500) and the pair of haptic devices (300).
[0055] Referring now to Figures 2 and 3, the system (100) includes an adapter unit (2) connectable to the one or more arms (310) extending from the pair of haptic devices (300). The adapter unit (2) is structured to receive at least a portion of at least one surgical tool (200) and is engageable with a portion of the training unit (500). The adapter unit (2) is configured to receive and transmit force between the at least one surgical tool (200) and the training unit (500). The adapter unit (2) includes a holder (21) connectable to the one or more arms (310) defined with a receiving portion (2a) to receive the at least one surgical tool (200). In an embodiment, the receiving portion (2a) includes one of a slot, a groove, an aperture (21a) and the like complementing an end portion of the at least one surgical tool (200) as shown in Figure 2. In an embodiment, the receiving portion (2a) is defined with an arcuate profile to adaptably receive different tools and assist the user (155) in mounting the at least one surgical tool (200) in different orientations relative to the holder (21) based on requirement. In an embodiment, the receiving portion (2a) is defined with at least one magnet (326), as shown in Figure 3, configured to connect to end portion of the at least one surgical tool (200), where the at least one surgical tool (200) is defined with a magnetic metal tip to connect to the at least one magnet (326) for accurately mounting the at least one surgical tool (200) on the holder (21). In an embodiment, the receiving portion (2a) includes a sleeve [not shown explicitly in Figures] rotatably disposed at the receiving portion (2a) configured to aid in rotation of the at least one surgical tool (200) relative to the holder (21) based on the training simulation. In an embodiment, the holder (21) includes a plunger [not shown in Figures] operatively connectable to the sleeve protruding out from the holder (21) and engageable with the training unit (500). The plunger is configured to receive and transmit movement of the at least one surgical tool (200) to the training unit (500). Further, the holder (21) includes a transmission mechanism [not shown in Figures] which may be including, not limited to, a gear mechanism, a rack and pinion mechanism and the like, operatively coupled between the sleeve and the plunger and disposed within the holder (21) to convert the rotation of the at least one surgical tool (200) to one of translation, rotation of the plunger to engage with the training unit (500) for simulating training of the surgical intervention. In the illustrative embodiment, the at least one surgical tool (200) is structured to resemble the actual surgical tools utilized in surgical interventions. In an embodiment, the holder (21) is defined by one of a cylindrical profile, cuboidal profile, etc. Such configuration of the holder (21) aids to simulate hands-on training for the user (155) with each tool (200) of the at least one surgical tool (200). In an embodiment, the holder (21) is defined with an aperture (21a) adjacent to the receiving portion (2a) to accommodate at least one auxiliary sensor [not shown in Figures] . The at least one auxiliary sensor includes one of a camera, fluorescence sensors, ultrasound probes and the like, which are used in tandem with the at least one surgical tools (200) in simulation of surgical interventions such as endoscopy, laparoscopy, etc as shown in Figure 6. Such configuration of the holder (21) having the aperture (21a) aids to simulate tandem operation of the at least one surgical tool (200) with the at least one auxiliary sensor to the user (155). In another exemplary embodiment, the tool (200) is mounted on arms (310) of one haptic device (300) and the auxiliary sensor is mounted separately on the holder (21) for individual operation of the at least one surgical tool (200) and the auxiliary sensor as shown in Figure 7. In an embodiment, the transmission mechanism is operatively coupled to the at least one auxiliary sensor and the plunger to simultaneously rotate or displace both the plunger and the auxiliary sensor during the training simulation. In an embodiment, the holder (21) may include separate transmission mechanisms for each of the plunger and the at least one auxiliary sensor to aid the user ( 155) to rotate or displace the plunger and the at least one auxiliary sensor separately and the same shall not be construed as a limitation.
[0056] Further, the adapter unit (2) includes an adapter (22) coupled to the one or more arms (310). The adapter (22) is structured to fixedly mount the at least one surgical tool (200) relative to the holder (21) and the one or more arms (310), where the adapter (22) is structured to compensate for length of the holder (21) as can be seen in Figure 2. In an embodiment, the holder (21) is connected to arms (310) of one haptic device (300) of the pair of haptic devices (300), while the adapter (22) is coupled between arms (310) of the other haptic device (300) and the receiving portion (2a) of the holder (21) as shown in Figure 2. The adapter (22) is defined by one of an serpentine profile, an inverted L-shaped profile, a Z-shaped profile and an arcuate profile etc. In the illustrative embodiment, the adapter (22) is depicted with an L-shaped profile as shown in Figure 3 to reduce the material required for the adapter (22) and enhance ease of mounting the at least one surgical tool (200). Further, the adapter (22) defined with a provision (22a) to removably accommodate and mount a portion of the at least one surgical tool (200) on the holder (21). The provision (22a) is structured to align with the receiving portion (2a) of the holder (21) where a portion of the at least one surgical tool (200) engages with the provision (22a) first and the receiving portion (2a) of the holder (21) while mounted on the adapter unit (2) as show in Figure 2.
[0057] In an illustrative embodiment, as seen in Figure 3, the system (100) is depicted with two haptic devices (300) to provide haptic feedback to the user (155), however, the same cannot be construed as a limitation as the number of haptic devices (300) may be varied based on design requirements of the system (100). However, the user (155) may need to use multiple tools (200) (up to 7 to 10 tools (200)) in a single surgical intervention which may be simulated by swapping out the tools (200). In an embodiment, the at least one surgical tool (200) includes a locking unit (290) configured to engage and disengage with the at least one tool rack (600) and the receiving portion (2a) of the holder (21). The locking unit (290) includes a lever (290) (shown in Figure 8) slidably disposable at an end portion of the each of the at least one surgical tool (200). The lever (290) is displaced to extend outward from the at least one surgical tool (200) to engage with the at least one tool rack (600) and the receiving portion (2a) of the holder (21) for locking the at least one surgical tool (200). The lever (290) is displaced back inward into the at least one surgical tool (200) to disengage with the at least one tool rack (600) and the receiving portion (2a) of the holder (21) for unlocking the at least one surgical tool (200). Such configuration of the locking unit (290) aids in locking and unlocking the at least one surgical tool (200) from the at least one tool rack (600) and the receiving portion (2a) using only one hand, thereby reducing complexity of connecting and disconnecting the at least one surgical tool (200) from the at least one tool rack (600) and the holder (21). In an embodiment, each tool (200) of the at least one surgical tool (200) are defined with a metal pin [not shown in Figures] and a head [not shown in Figures] to assist the user ( 155) to align the tool (200) with the adapter (22) on the one or more arms (310) of the haptic device (300) and lock the tool (200) in with a push of lever (290) of the locking unit (290). The at least one surgical tool (200) is released from the haptic device (300) by activating the lever (290) on a side of the at least one surgical tool (200).
[0058] Referring back to Figures 1c and Id, the system (100) includes at least one first connector (401) defined with a first predefined profile. The at least one first connector (401) is detachably connectable between the base (1) and one of the pair of haptic devices (300). The at least one first connector (401) is structured as one of a plate, an arm etc., structured to extend between one of the pair of haptic devices (300) and the base (1). In an embodiment, the first predefined profile of the at least one first connector (401) includes one of a straight profile, Y-shaped profile, T-shaped profile, L-shaped profile, V-shaped profile, an arcuate profile and the like having at least two ends. In an embodiment, the number of ends and profile of the at least one first connector (401) may be varied based on design and space requirements of the system ( 100) and the same shall not be construed as a limitation. In the illustrative embodiment, the at least one first connector (401) is depicted with a Y-shaped profile having three ends as shown in Figures 1c and Id. Such configuration of the at least one first connector (401) aids to connect one of the pair of haptic devices (300) at one end, connection to the base (1) at one end and connection to a tool rack (600) accommodating the at least one surgical tool (200) at the other end. Such first predefined profile of the at least one first connector (401) aids to position the haptic device (300) and the tool rack (600) in a specific training layout and such position is variable based on alignment of the at least one first connector (401) with the base (1). For example, when the at least one first connector (401) is defined as a Y-shaped predefined profile, the haptic device (300) is connected to one arm of the Y-shaped profile, the base (1) is connected to another arm of the Y -shaped profile an the tool rack (600) is connected at a stem portion of the Y-shaped profile to position the haptic device (300) and the tool rack (600) proximal to each other as shown in Figures 1c. In one implementation, the system (100) includes different shaped first connectors as shown in Figure 1c, where the first connector (401) with Y-shaped profile is detached and the at least one first connector (401) having T-shaped profile is connected to the base (1), the haptic device (300) and the tool rack (600) to position the haptic device (300) and the tool rack (600) away from each other as can be seen in Figures 5a and 5b. The at least one first connector (401) includes a first set of coupling portions (401a) complementing the plurality of engaging portions (11) of the base (1). The first set of coupling portions (401a) may be in the form of a slot, a groove, a ring, and the like complementing the plurality of engaging portions (11) of the base (1). In the illustrative embodiment, the plurality of engaging portions (11) are depicted as projections and the first set of coupling portions (401a) are depicted as dove shaped slots as clearly shown in Figures lb and 1c and the same shall not be construed as a limitation as the same may be varied based on design requirements of the at least one first connector (401) and the base (1).
[0059] Referring now to Figures lb and 1c, the system (100) includes at least one second connector (402) defined with a second predefined profile. The at least one second connector (402) is detachably connectable between the base (1) and one of the pair of haptic devices (300). The at least one second connector (402) is structured as one of a plate, an arm etc., structured to extend between one of the pair of haptic devices (300) and the base (1). In an embodiment, the second predefined profile of the at least one second connector (402) includes one of a straight profile, a Z-shaped profile, arcuate shaped profile, L-shaped profile, V-shaped profile, an arcuate profile and the like having at least two ends. In an embodiment, the number of ends and profile of the at least one first connector (401) may be varied based on design and space requirements of the system (100) and the same shall not be construed as a limitation. In the illustrative embodiment, the at least one second connector (402) is depicted with an elbow-shaped profile having two ends as shown in Figures lb and 1c. Such configuration of the at least one second connector (402) aids to connect one of the pair of haptic devices (300) at one end, and connect to the base (1) at the other end. Such second predefined profile of the at least one second connector (402) aids to position the haptic device (300) and base (1) in a specific training layout and such position is variable based on alignment of the at least one second connector (402) relative to the base (1). For example, when the at least one second connector (402) is defined as an elbow shaped predefined profile, the haptic device (300) is connected to one end of the at least one second connector (402), where the base (1) is connected to another end of the at least one second connector (402) to position the haptic device (300) away from the base (1) and the other haptic device (300) connected to the at least one first connector (401) as shown in Figures 1c and Id. In one implementation, the system (100) includes different shaped second connectors as shown in Figure 1c, where the at least one second connector (402) with elbow shaped profile is detached and the at least one second connector (402) having Z-shaped profile is connected to the base (1), and the haptic device (300) to position the pair of haptic devices (300) diametrically opposite to each other as can be seen in Figures 6a and 6b.

In an embodiment, the at least one first connector (401) and the at least one second connector (402) are made of one of Polymethyl methacrylate, aluminum, titanium, stainless steel etc and combinations thereof. Based on the strength and tolerance required for each type of training simulation, the material of the at least one first connector (401) and the at least one second connector (402) is varied. Further, the at least one first connector (401), and the at least one second connector (402) are detachably connectable to the base (1) to position the pair of haptic devices (300) relative to the base (1) based on the first predefined profile and the second predefined profile. In the illustrative embodiment, the at least one first connector (401) with the first predefined profile of Y -shaped profile having three ends and the at least one second connector (402) with the second predefined profile of elbowshaped profile result in a first training layout as shown in Figures 1c and Id. In another illustrative embodiment, the at least one first connector (401) having T-shaped profile and the at least one second connector (402) having Z-shaped profile are connected between the base (1) and the pair of haptic devices (300) resulting in a second training layout. In an embodiment, the first training layout may correspond to simulation of a spinal surgery where the at least one surgical tool (200) is aligned proximal to a top portion of the training unit (500) as shown in Figures 1c and Id and the second training layout may correspond to a knee surgery where the at least one surgical tool (200) is aligned proximal to a bottom portion of the training unit (500) as shown in Figures 6a and 6b. Such configuration of the at least one first connector (401) and the at least one second connector (402) aids to define different training layouts and orient the at least one surgical tool (200) in different orientations relative to the training unit (500) in each layout corresponding to the training simulation. Such configuration of the system (100) aids to train the user (155) for multiple training simulations relating to different surgical interventions in a single system, without requiring dedicated training systems for each training simulation of different surgical interventions. Further, such configuration of the system (100) may simulate surgical interventions with enhanced experience with adequate forces and corresponding training layout for the user (155), thereby enhancing hands-on experience in surgical interventions. With such configuration, the system (100) may reduce or eliminate potential complications and adverse outcomes for the patients due to lack of hands -on experience.

In an embodiment, the body (601) may be defined by one of a cuboidal profile, cubical profile, etc, to removably accommodate the at least one surgical tool (200). The at least one tool rack (600) is defined with a third set of coupling portions (601a) configured to couple the at least one tool rack (600) to one of the at least one first connector (401) and the at least one second connector (402). The at least one tool rack (600) is detachably connectable to the first set of coupling portions (401a) and the second set of coupling portions (402a). The third set of coupling portions (601a) are defined with a profile complementing the plurality of engaging portions (11) of the base (1). In an embodiment, the third set of coupling portions (601a) may be in the form of a slot, a groove, a ring, and the like, which complement the plurality of engaging portions (11) of the base (1). In the illustrative embodiment, the plurality of engaging portions (11) are depicted as projections and the third set of coupling portions (601a) are depicted as dove shaped slots as shown in Figures 8, lb and 1c and the same shall not be construed as a limitation as the same may be interchanged or varied based on design requirements of the at least one tool rack (600), the at least one first connector (401) and the at least one second connector (402).

Further, the at least one tool rack (600) may be structured to accommodate the at least one surgical tool (200), where the number of surgical tools (200) accommodated may be varied based on number of training simulations performed through the system (100). In the illustrative embodiment, the one or more mounting portions are depicted as four slots defined on the body (601) as shown in Figure 8 to accommodate four surgical tools (200) and the same shall not be construed as a limitation. Further, the four surgical tools (200) are defined based on surgical tool (200) interfaces in the operating room such as knives, graspers, punches, drills, cameras, sleeves, retractors, scissors, curette, probe, needle holder, dilator, sleeve etc. and interface mechanism of each such tool (200) (how the user (155) holds the tools (200) and the mechanism by which the tools (200) are activated).

[0066] Referring now to Figure 14, the system (100) includes a first plurality of sensors (801) disposed within the adapter unit (2) and each of the at least one surgical tool (200). For example, the first plurality of sensors (801) may be including not limited to, ultrasound sensors, proximity sensors, Infrared sensors, etc. In an embodiment, the first plurality of sensors (801) may include a variety of proximity sensors such as inductive, capacitive, optical, magnetic, and ultrasonic.

For example, the at least one first connector (401) is disposed with the second plurality of sensors (802) at three ends of the defined with the first set of coupling portions (401a). For example, the second plurality of sensors (802) may be including, not limited to, ultrasound sensors, proximity sensors, Infrared sensors, etc. In an embodiment, the second plurality of sensors may include a variety of proximity sensors such as inductive, capacitive, optical, magnetic, and ultrasonic. The second plurality of sensors (802) are configured to transmit at least one second signal corresponding to the training layout of the at least one first connector (401) and the at least one second connector (402). In an embodiment, each connector of the at least one first connector (401) and the at least one second connector (402) include at least two sensors of the second plurality of sensors (802), where each sensor is configured to transmit a second signal corresponding to the training layout based on connection of the at least one first connector (401) and the at least one second connector (402) with the base (1). In such configuration, each sensor at each end of the at least one first connector (401) and the at least one second connector (402) is marked where the at least one second signal indicate the training layout of the system (100).
[0068] Further, the system (100) includes the control unit (700) communicatively coupled to the pair of haptic devices (300), the first plurality of sensors (801), the second plurality of sensors (802), the at least one first connector (401), the at least one second connector (402) and the at least one tool rack (600). The first plurality of sensors (801) are configured to transmit the at least one first signal to the control unit (700) and the second plurality of sensors (802) are configured to transmit the at least one second signal to the control unit (700). The control unit (700) is configured to identify a type of the at least one surgical tool (200) received by the adapter unit (2) based on the at least one first signal. Further, the control unit (700) identifies a training layout from the at least one second signal corresponding to connection between the at least one first connector (401), the at least one second connector (402), the pair of haptic devices (300) and the at least one tool rack (600).

[0069] Further, the control unit (700) determines a training simulation based on the training layout and the type of the at least one surgical tool (200) received by the adapter unit (2).

Further, the control unit (700), then, regulates operation of the pair of haptic devices (300) to provide haptic feedback to the adapter unit (2) based on the determined training simulation to perform the training simulation. For example, the control unit (700) regulates operation of the pair of haptic devices (300) to increase resistive force to the adapter unit (2) and the at least one surgical tool (200) corresponding to tension and bone strength of the spinal surgery intervention upon determining the training simulation to be spinal surgery.

The at least one third sensor is configured to transmit at least one third signal corresponding to type of training unit (500) being mounted on the base (1). For example, each type of training unit (500) is marked for identification of the training unit (500) being mounted on the base (1) and corresponding third signal is transmitted to the control unit (700) upon mounting of the training unit (500) on the base (1). The control unit (700) is then configured to identify a type of the at least one surgical tool (200) received by the adapter unit (2) based on the at least one first signal, and identifies a training layout from the at least one second signal and the at least one third signal corresponding to type of training unit (500) mounted on the base ( 1) . Further, the control unit (700) determines a training simulation based on the training layout, the type of the at least one surgical tool (200) received by the adapter unit (2), and the type of training unit (500) mounted on the base (1). For example, the control unit (700) determines the training simulation as simulation of spinal surgical intervention, upon determining the at least one surgical tool (200) to be the angular trigger (210) based on the at least one first signal, upon identifying the layout to be the first layout corresponding to the spinal surgery, and upon identifying the training unit (500) as a spinal surgical training unit (500) from the at least one third signal. Further, the control unit (700), then, regulates operation of the pair of haptic devices (300) to provide haptic feedback to the adapter unit (2) based on the determined training simulation to perform the training simulation. Such configuration of the control unit (700) regulating the operation of the pair of haptic devices (300) based on the at least one first signal, the at least one second signal and the at least one third signal aids to enhance accuracy of determining the training simulation and the haptic feedback required for the same.
[0071] According to an embodiment, the control unit (700) may be an edge computing device, personal computing device, a workstation, a client device, a network enabled computing device, any other suitable computing equipment, and combinations of multiple pieces of computing equipment. As used herein, “edge computing” refers to computing that is capable of being performed by an edge device, which is a compact computing device that has a small form factor and resource constraints in terms of computing power. In an embodiment, the control unit (700) is configured on a cloud computing -based platform on a cloud computing environment, implemented as a service for analyzing data. As used herein, “cloud computing” refers to a processing environment including configurable computing physical and logical resources, for example, networks, servers, storage, applications, services, etc., and data distributed over the network, for example, the internet. The cloud computing environment provides on-demand network access to a shared pool of the configurable computing physical and logical resources. The network is, for example, a wired network, a wireless network, a communication network, or a network formed from any combination of these networks. Additionally, control personnel may access the control unit (700) via the GUI. The GUI is, for example, an online web interface, a web based downloadable application interface, etc.
[0072] In an example, considering simulation of the user (155) holding a scalpel and trying to make an incision on the back of the patient. The weight of the scalpel is a physical property that is simulated using equation of F = mg, where ‘m’ is described as the mass of the scalpel and ‘g’ is the acceleration due to gravity (vector). ‘F’ is generated as a force vector that signifies the forces in X, Y and Z directions (cartesian coordinates). The force vector is sent to the pair of haptic devices (300) by converting into torque using a Jacobian matrix. The Jacobian matrix allows conversion of parameters from joint space to the cartesian space and vice versa, using below mentioned equation (1)
[0073] Torque = Transpose (Jacobian) x F . (1)
[0074] The torque is then applied to motors of the haptic device (300) to simulate the one or more haptic properties. A series of torques are generated from a series of forces generated at a rate of one force / torque vector per milli second or less. Similarly, forces encountered during cutting, drilling, pushing grabbing, punching using different tools (200) like scalpel, rongeur, punch, drills, electro-probe etc. are measured appropriately using force sensors and the torque may be applied to the haptic device (300). The physical properties are quantified from real objects using common standardized test for each property. For example, the Brinell test is used for determining the hardness of real objects. Weight of objects is measured on a weighing scale. Also, the physical properties for known objects and materials may be directly obtained from standardized numbers catalogue. The user (155) is guided to remove the epidural fat with probe. The weight of the probe may be applied on the motors of the haptic device (300), when the user (155) is undertaking the training simulation through the system (100). Also, when the user (155) does not remove the epidural fat entirely, a sensation may be provided as haptic feedback using the haptic device (300).
[0075] The build and layout of the system (100) depends on the type of surgical procedure that is simulated using dynamic virtual patients for computer-based medical training. The workspace and layout of the user (155) needs to be mapped so that the movements the trainee / user (155) makes are identical to the movements performed in the operating room. To accomplish this, as shown in Figure la, the system (100) is designed in a modular manner wherein the workspace / layout can be easily adjusted using the at least one first connector (401) and the at least one second connector (402) to be arranged in multiple layout configurations. The at least one first connector (401) and the at least one second connector (402) also lock the docking position of every component of the system (100) by locking mechanisms such as spring loaded Bal-latch, spring loaded Bal-catch, push latch mechanism etc. As depicted in Figures la to 7, the at least one first connector (401) and the at least one second connector (402) are configured to be assembled in numerous ways and easily by reducing the time taken to switch workspaces between different training simulations. Such utilitarian modularity in of the system (100) aids configuration of workspace layout for numerous types of computer-based medical training simulations.
[0076] In an operational embodiment, in order to operate the system (100), the base (1) is mounted with a training unit (500) corresponding to the training simulation being performed. The training unit (500) is detachably supported on the base (1). The at least one first connector (401) and the at least one second connector (402) are chosen based on training simulation and are connected to the base ( 1 ) at the plurality of engaging portions (11), where the first set of coupling portions (401a) and the second set of coupling portions (402a) are connected to the plurality of engaging portions (11). Further, the pair of haptic devices (300) are connected to the at least one first connector (401) and the at least one second connector (402) and the at least one tool rack (600) is connected to one of the at least one first connector (401) and the at least one second connector (402) as shown in Figure 4a.

Upon connection of the at least one first connector (401 ), the at least one second connector (402) and the at least one surgical tool (200), the first plurality of sensors (801) are configured to transmit the at least one first signal to the control unit (700) and the second plurality of sensors (802) are configured to transmit the at least one second signal to the control unit (700). The control unit (700) is configured to identify a type of the at least one surgical tool (200) received by the adapter unit (2) based on the at least one first signal. Further, the control unit (700) identifies a training layout from the at least one second signal corresponding to connection between the at least one first connector (401), the at least one second connector (402), the pair of haptic devices (300) and the at least one tool rack (600). In an embodiment, the third set of coupling portions (601a) are defined with the second plurality of sensors (802) configured to transmit the at least one second signal corresponding to mounting of the at least one tool rack (600) relative to the at least one first connector (401) and the at least one second connector (402).
[0077] Further, the control unit (700) determines a training simulation based on the training layout and the type of the at least one surgical tool (200) received by the adapter unit (2).
