Description

• PORTABLE ELECTROMECHANICAL DEVICE WITH POSITIONING AND DRIVING SYSTEM FOR DETECTION OF THREE-DIMENSIONAL MOVEMENTS, CONTROL AND INTERACTION IN VIRTUAL ENVIRONMENTS ”This report relates to a patent application for a pen-shaped device. A portable device whereby, upon pressure from its retractable tip 1 (sliding by means of a piston attached to an encoder) on the contact surface of a computer, the user is given information about the desired or reached depth point. In case of radial movements the pen also gives the user information (by means of accelerometer) on inclines.

This pen enables the three-dimensional interaction in a virtual environment (on the computer) where a human organ such as the liver is represented, for the user to "move" in that environment through the desired angle and depth of view, sharpening with great perfection compared to the simulation of simpler surgical procedures.

TECHNICAL STATE

As is well known, in surgical settings, the presence of a physician with greater professional baggage is usually required. This presence is necessary for guidance regarding the procedures to be taken by a novice physician.

Despite the unquestionable efficiency of academic study, the apprentice generally remains at the beginning of his career at the mercy of the emergence of patients with specific problems and only then will he form, with real contact, his course of action over the working time.

In the case of routine surgeries, ie minor surgeries, there is currently no training system that simulates these possible problems brought by patients. An even virtual training system would certainly provide support not only for novice doctors but also for experienced doctors, either by assisting them or by: reminding them of procedures to be put in place at the time the problem arises.

OBJECTIVE OF THE PATENT The pen in question and the system that surrounds it, reasons for this patent application, precisely provide, with absolute real age, the medical training and knowledge in small and medium size surgeries, effectively familiarizing the apprentice with the possible clinical problems and greatly assisting you in the procedures to be taken when the actual moment of medical action.

Superficially explained, the pen goes on to the system to be further detailed; through the attached drawings, through which we can see: Figure 1 - view and nerspective, showing the pen in position of use;

Figure 2 - exploded perspective view showing the parts of the pen, the housing of which is composed of handle body and base. As noted, internally the pen houses a wired printed circuit board for connection to a computer. Such a printed circuit board is integrated with acceleration sensors, a central actuator knob and an encoder. The encoder receives a stop-tipped scale on which a spring is housed, forming a piston at the base of the pen. In detail A. at the side, the piston assembly is shown in perspective;

Figures 3, 4 and 5 - sectional views of the pen connected by its cable to a computer, in which is installed a program, specifically for simulating the training of minor surgeries. The pen is tipped against the computer's touch pad and was initially pressed, compressing the spring and sliding the scale through the encoder. In this condition, the encoder reads the sliding motion of the scale and sends such information to the program, which reproduces, on screen, the approximation of the environment for the visualization of the desired object, such as the simulation of a liver to be analyzed. In figures 4 and 5, the approximation of the object on the screen is greater, as the pressure imposed by the user increases from the tip;

Figure 6 - Perspective view of the tip supported on the touch pad after desired approximation with the pressure by the tip, when the pen is then rotated and such information is detected by the accelerometers that send the signal to the computer. In this condition, the program interprets this information, reproducing in the web the rotation of the environment, guided by the movement of the pen.

Figure 7 - Views of the virtual environment exposed on the computer screen, showing in sequence that, as the pen rotates, the user can “move” at any angle in this environment. Thus, through the possibilities of turning and reaching depth in the environment, the user, handling the actuator button, can interact at the desired point, simulating the surgical procedures with great perfection.

Figures 8 and 9 - views of the pen being used on a tablet touch pad e. next to it, being used directly on the touch screen of a computer.

In accordance with the accompanying drawings, “DEVICE 1: PORTABLE LETROMECHANICAL, WITH POSITIONING AND DRIVING SYSTEM FOR DETECTION OF THREE-DIMENSIONAL MOVEMENTS, CONTROL AND INTERACTION IN VIRTUAL MOBILE”, is the object of this application. from a portable pen-shaped device (1), composed of handle body (2) cast at the upper edge by a hole (3) and another hole (4), at an intermediate point, forming the web. at the lower edge, an inner diametrical tooth (5) with opening (o). By the inner tooth (5) the handle body (2) receives the coupling of the base (7). It is also cast by a central hole (8) and surrounded by an internal frieze (9).

According to the project, the pen (1) receives a printed circuit board (10) with cable (C) for connection to a computer (CO), being integrated with acceleration sensors (11), besides an actuator button (12) and an encoder (13), working with a scale (14) with nozzle (15) incorporating anvil (16), a spring receiver (17).

According to the proposed arrangement, the printed circuit board (10) is supported on the inner tooth (5) of the lower edge of the handle body (2), which has the hole (3) of its upper edge surpassed by the cable (C). . The actuator button (12) is in turn exposed externally to the handle body (2) through its intermediate hole (4). The scale (14) is mounted vertically and internally at the base (7) of the cage (1), so as to exceed the encoder (13) of the printed circuit board (10), while the tip (15) surpasses the central hole. (8). Said nozzle (15) is delimited next to the inner surrounding frieze (9) of the base (7), by its stop (16), which receives the abutment of the ends of the spring (17), whose opposite end abuts the tooth inside (5) of the lower edge of the handle body (2).

Thus assembled for use in any suitable environment, the user connects the pen (1) by its cable (C) to a computer (CO) or tablet (TA) that has a specific program installed on its CPU. simulate simple surgery training, to which the printed circuit board (10) is integrated, according to the intended three-dimensional electronic system.

Mechanically, while holding the pen (1) held by the amateur button (12), the user rests the tip (15) on the touch pad surface (S) (in the case of a tablet) or directly on the computer screen ( CO), when then the stop (16) slides through the base (7) and compresses the spring (17) against the inner tooth (5) of the lower edge of the handle body (2), making the scale (14) surpass the encoder (13) of the printed circuit board (10). In this condition, the encoder (13) reads this sliding movement of the scale (14) and such information, interpreted by the printed circuit board (10), is sent to the computer (CO), whose surgery training simulator program reproduces, on screen. , the approximation of the environment to the visualization of an object (O), for example a human organ, from the exact desired depth point.

Depending on the pressure imposed from the tip (15) of the pen (1), the approximation of the object (O) on the screen is greater, when the user, by pressing the actuator button (12), can interact at this point.

This depth information is combined with the rotation of the pen (1), whose movements, detected by the accelerometers (11) are also interpreted by the printed circuit board (10), which also sends the signals to the computer (CO). The surgery training simulator program reproduces on screen such movements made by the pen (1), so that the user has a view from any angle of the environment, the desired point of the object (O), also interacting in the image, with the actuation of the actuator button (12).

Thus, through the unprecedented constructivity of the pen, a system is made possible by which the user “penetrates” the image environment (O) to be treated, bringing it and rotating it for analysis from any desired angles, interacting three-dimensionally. This is achieved by actuating the actuator button (12) as a surgical tool, perfectly simulating training and studies essential for future practical medical procedures.
