    [0005] The present invention relates to an automatic ostomy disc cutting device that facilitates the cutting of the ostomy disc to the specific and exact shape of the stoma of the patient-user.
    [0006] The scope of application in which the present invention is framed is that of the devices for preventing complications derived from the ostomy and improving the quality of life of ostomized people.
    [0007]
    [0008]
    [0009] The ostomy is a surgical intervention that generates a hole (stoma) in the abdominal wall to give way to the fecal or urinary matter, which must be collected through a bag that adheres to the abdomen, around the stoma. This intervention is necessary as a result of several diseases of different types: Cancer, Crohn's disease, chronic ulcerative colitis, diverticulitis, or familial adenomatous polyposis, among others.
    [0010] People with a stoma in the abdominal wall are known as ostomized people and colloquially they are known as "people with a bag" because they carry a bag attached to their abdomen that collects urine or feces. The ostomy is an alteration of the body image, loss of voluntary control of stool and / or urine evacuation, and the need to use a bag to store stool and / or urine.
    [0011]
    [0012] In addition to the psychological and social consequences of living with a bag, the stoma has a high complication rate, at least 50%. Among other complications, the stoma may develop infection, hernia, necrosis, dehiscence or skin disorders. Skin disorders are the most frequent reason for attention in the consultation of stomaterapia, are difficult to manage, cause stool leakage and have a significant cost to the health system. The most frequent cause of skin complications is a poor adjustment of the adhesive disc, which results in the exposure of peristomal tissue to the effluent. Ensuring good stoma care and an exact fit between the ostomy disc and the stoma contour are the simplest and most effective preventive measures to prevent skin complications, especially in the case of ileostomies, where the effluent is very alkaline.
    [0013] Despite being an intervention with frequent complications and a very negative chronic impact on the patient's quality of life, currently, there are no solutions that have the possibility of radically eliminating or reducing the ostomies that are performed and, although they have been explored Different lines of research to look for alternatives to this type of surgery, are still dealing with an unresolved medical need. Even in interventions such as proctocolectomies or ileoanal reservoirs, indicated to build a "new rectum" with small intestine in cases of panproctocolectomies due to ulcerative colitis or familial adenomatous polyposis, high rates of dysfunctionality or complications often make it necessary to replace them with an ostomy.
    [0014] Since clinical alternatives that replace the ostomy technique in an efficient way and with fewer complications are not visible in the medium term, it is essential to dedicate efforts to the development of technologies that solve the complications posed by the ostomy and make life easier for ostomized people.
    [0015] The devices currently available to cut the ostomy disc are not exact or adaptable to each stoma.
    [0016] In most cases, patients cut the ostomy disc with scissors (either common or curved scissors specifically for cutting ostomy discs), after measuring their stoma with a series of circular templates. The result will never adapt exactly to the stoma contour, especially for those patients whose abilities Instruments are diminished by age, loss of vision or other pathologies.
    [0017] In addition to common or curved scissors specifically for cutting ostomy discs, there are also other types of devices especially suitable for cutting ostomy discs, for example, the device marketed under the name "Pok Ostomy." Limitations of these devices are as follows:
    [0018] - These devices only make circular holes. They do not adapt to stomata with a contour other than the circular, elongated stomata or with irregular contours.
    [0019] - Stoma size is measured with circle templates of discrete sizes. This measurement means that the hole size does not correspond exactly to the size of the stoma.
    [0020] - These perforating devices can only be used for ostomy discs that do not come integrated with your bag (if used with integrated ostomy bags, they would pierce the front of the bag when cutting the disc).
    [0021] Due to these limitations, there will always be differences between the stoma contour and the resulting cut after perforation.
    [0022] Therefore, it would be desirable to find an ostomy disc cutting device that would adjust the cutting of the ostomy disc to the exact shape of the stoma.
    [0023]
    [0024]
    [0025] To overcome the aforementioned drawbacks, the present invention comprises an ostomy disc cutting device that adjusts the cutting of the ostomy disc to the exact shape of a user's stoma.
    [0026] The ostomy disc cutting device, unlike other devices, is capable of cutting the two main types of ostomy bag systems:
    [0027] These systems are:
    [0028] - One piece systems. They consist of a bag and an adhesive disk that are permanently attached. This type is characterized in that at the time of having to replace the bag, the entire system is discarded.
    [0029] - Two piece systems. They include a separate bag and a disk. In these systems, the bag can be removed without changing the adhesive disc.
    [0030] In a first aspect of the invention, an automatic ostomy disc cutting device is disclosed. The automatic ostomy disc cutting device comprises: a system for attaching an ostomy disc to the automatic ostomy disc cutting device; a cutting system comprising cutting means; a positioning system comprising means of displacement of the cutting system with respect to the clamping system; an electronic system comprising: communication means configured to receive coordinates of a stoma of an ostomized subject from an image registration and treatment system, which registers an image of the stoma and calculates the stoma coordinates in correspondence with a outer perimeter of the stoma shape; and, a microprocessor for the control of the positioning system and the cutting system. The electronic system receives the coordinates of the stoma and acts on the positioning system and on the cutting system in such a way that the cutting means make a cut on the ostomy disc describing a path equivalent to the outer perimeter of the stoma shape. The media can be wireless (WiFi, 4G, etc.) or by cable (USB, network).
    [0031] In one embodiment of the invention, the positioning system comprises: a radial movement system comprising radial displacement means of the cutting system with respect to a base of the device; and, an angular movement system that It comprises angular displacement means of the fastening system with respect to the base of the device. The angular displacement means comprise: an angular motor; a pinion; a gear; a lower disc fixed to the base of the automatic cutting device by means of a support; an intermediate disk fixed to the lower disk; an upper disk with the possibility of circular movement with respect to said intermediate disk, which together with the lower disk guides the upper disk in its angular displacement movement; magnets arranged on the upper surface of the upper disk. Where the angular motor transmits an angular movement to the pinion that meshes with the internally arranged gear along the smaller circumference of the upper disc, such that the angular motor generates a circular movement of the upper disc with respect to an axis perpendicular to the geometric center of the upper and lower discs.
    [0032] In one embodiment of the invention, the fastening system is a ring. The intermediate disk, the lower disk and the ring are made of Teflon or plastic material such as polypropylene, and where the ring has magnets distributed along its polarity surface contrary to that of the magnets contained in the upper disk. Optionally, the intermediate disk and the lower disk are materialized in Teflon or in plastic material such as polypropylene, and where the ring is materialized in a material selected from a ferromagnetic material and a magnetized material of polarity contrary to that of the magnets contained in the upper disk
    [0033] Additionally, the radial displacement means comprise: a radial motor; a radial motor support that mechanically fixes the radial motor to the base of the device; a support of the cutting system; a guide support; a guide; a zipper stand; A zipper; a pinion; where the radial motor transmits a radial movement to the cutting system by means of the pinion located on the axis of the radial motor, such that the pinion meshes with the rack whose support is mechanically linked to the support of the cutting system that supports the cutting system . The support of the cutting system has an inverted "U" shape and comprises two guides at the ends of said "U", where said guides slide internally through the guide supports for radial displacement of the cutting system.
    [0034] Optionally, the radial movement system may comprise a limit switch support to limit the movement of the radial movement system.
    [0035] In one embodiment of the invention, the cutting means is a blade and the cutting system comprises a rotary motor that allows the blade to be rotated at any angle between 0 ° and 360 ° with hourly and counterclockwise movements.
    [0036] In an alternative embodiment of the invention to the previous embodiment, the cutting means is a blade and the cutting system comprises an axis of free rotation misaligned from the blade a predetermined distance. The predetermined distance between the free rotation axis and the blade (cutting part of the blade) allows free angular positioning of the cutting part of the blade. In this case, the electronic system recalculates the trajectory by moving each coordinate a distance equivalent to the distance between the free axis and the cutting part of the blade, in the direction tangent to the cut.
    [0037] In an embodiment of the invention, the cutting system additionally comprises a blade holder and a protective piece. The protective piece will minimize the risk of accidental injury to the user, and may mean that the device is considered safe in airports and other places of controlled access.
    [0038] In an embodiment of the invention the cutting system additionally comprises a blade having a horizontal "V" shape.
    [0039] In a second aspect of the invention, an ostomy disc cutting kit ("kit") comprising the automatic ostomy disc cutting device defined in the first aspect of the invention, a recording and treatment system of the invention is disclosed. images and calibration means.
    [0040] In one embodiment of the invention, the calibration means are selected from adhesive calibration elements and at least one collimated light source. One type of collimated light source is the laser. A 3D calibration system includes several sources of collimated light.
    [0041] With the device object of the present invention, it is possible to reduce the high rate of periestomal complications in ostomized patients, caused by a poor adjustment of the adhesive disc around the stoma, while at the same time providing ostomized patients with greater autonomy and better quality of life thanks to the simple and automatic use of the device, which does not require instrumental skills or previous knowledge.
    [0042] Adjusting the stoma contour ostomy bag is essential to avoid stoma complications. A poor adjustment of the disc to the contour of the stoma will cause irritation of the peristomal tissue by contact with feces or urine (chemical dermatitis by contact with the effluent). A bad adjustment of the ostomy disc is also a risk factor for complications as serious as invasive fungal infections.
    [0043] The device of the present invention has a very easy and safe operation, accessible even to ostomized patients presenting with physical or intellectual disability or impairment or those with limitations in their instrumental skills. With the device of the present invention, these patients will not depend on a caregiver to measure and cut the disc, reducing their degree of dependence and improving their quality of life as a consequence.
    [0044] With the device of the present invention, a better adjustment of the ostomy disc which is an adhesive disk is achieved, which will also prevent the bad odors produced by the effluent from escaping from the bag. Containment of bad odors is essential so that ostomized patients can have a social and professional life as satisfactory as possible.

    [0054] Figure 13 shows the ostomy disc automatic cutting device of the present invention, an ostomy disc to be cut and the image recording and recording device, which carries a laser calibration device.
    [0055] In order to arrive at a better understanding of the object and functionality of the present invention, an embodiment of the present invention is detailed below with reference to the figures, without any limitation on the scope of the present invention.
    [0056] The device shown in Figures 1 to 10, 12 and 13 is configured to implement polar coordinates that determine the stoma contour. The implementation in polar coordinates is preferred over other configurations because they allow a power and a size of cutting device suitable for any ostomy disc and a cut of the optimized disk to the exact shape of the stoma. That is, the device is small in size and powerful to cut ostomy discs accurately, automatically and quickly, including discs integrated with your bag. The cutting in polar coordinates is implemented by combining the following actions:
    [0057] one.
    [0058] 2. - moving, by translation, the cutting system (the blade or other cutting means) in the radial direction;
    [0059] 3. - rotating the blade (or equivalent cutting means).
    [0060] Actions 1 and 2 would be automated using engines (1.5.1, 1.6.1). Action 3 can also be automated by means of a motor (1.7.1) or be free spin.
    [0061] An embodiment of an automatic ostomy disc cutting device 1 according to the present invention is shown in Figure 1 where the magnetized ring 1.4 attaches the ostomy disc 2 to the cutting device 1. Figure 2 shows the same device Figure 1 where the device 1 comprises the side housing 1.1, the top cover 1.2, the center cover 1.3, the magnetized ring 1.4 and the rotation axis 1.13.
    [0062] Figure 3 shows the same device of Figure 2 without the side casing 1.1, neither the covers 1.2 and 1.3, nor the magnetized ring 1.4, in this way the internal components of the device are observed. As shown in Figure 3, the device comprises the angular movement system 1.5, the radial movement system 1.6, the cutting system 1.7 and the electronic system 1.11. The electronic system 1.11 also has the microprocessor 1.11.2 for the control of the motors and the wireless communication means 1.11.1 for the communication with the registration and image processing system 4 (see figs. 11-13). The image registration and processing system 4 may be implemented by a mobile device in which a specific image registration and processing software application is executed. Additionally, the device comprises the lower base 1.8 that serves as support for the other components. The device also comprises support elements such as support 1.10 of the angular movement system 1.5 and support 1.9 of the upper cover 1.2.
    [0063] Figures 4 and 5 show the angular motion system 1.5 whose functionality is to rotate the ostomy disc in the horizontal plane in a clockwise and counterclockwise direction between 0 ° and 360 °. The angular movement system 1.5 is comprised of the angular motor 1.5.1, on whose axis the pinion 1.5.2 is located, which meshes with the gear 1.5.3 arranged internally along a circumference located at a height between the lower disk 1.5.4 and intermediate disc 1.5.5 that make up a “sandwich or sandwich” structure. The upper disc 1.5.6 located on intermediate disc 1.5.5 has 1.5.7 magnets distributed along its upper surface to attract the ring magnetized 1.4 The ring is magnetized with inverse polarity to magnets 1.5.7 or, alternatively, ring 1.4 may be made of some ferromagnetic material such as iron, cobalt or nickel alloys, on the lower disk 1.5.4 and fixed to the same, an intermediate disk 1.5.5 is placed, which serves as a guide along with the lower disk 1.5.4 for the upper disk 1.5.6 allowing movement circular upper disc 1.5.6. The middle 1.5.5 and lower 1.5.4 discs are preferably made of Teflon or polypropylene because it represents the best compromise solution between resistance and wear. The middle 1.5.5 and lower 1.5.4 discs are fixed to the base of the device 1.8 by means of the supports 1.10. With the indicated configuration, the angular movement system 1.5 (1.5.1, 1.5.2, 1.5.3, 1.5.4, 1.5.5, 1.5.6, 1.5.7) ensures high precision in the angular movement of the disc of ostomy on the central axis 1.13 of the automatic cutting device. Although not shown in Figure 4, in use, the ring 1.4 is placed on the upper disc 1.5.6 with interposition of the ostomy disc 2 being cut. The ring 1.4, therefore, has the same angular movement as the upper disc 1.5.6.
    [0064] Figures 6 and 7 show the radial movement system 1.6 and the cutting system 1.7 with an extension of said cutting system 1.7 shown in Figure 8. The radial movement system 1.6 is intended to move the cutting system 1.7 in a manner radial. The radial movement system 1.6 is comprised of the 1.6.1 radial motor on whose axis is the pinion 1.6.9 that meshes with the 1.6.7 rack whose support 1.6.6 is mechanically linked to the support of the cutting system 1.6.3 which supports the cutting system 1.7. The support of the cutting system 1.6.3 has an inverted "U" shape and has two 1.6.5 guides, preferably made of Teflon or plastic material such as polypropylene, at the ends of said "U", where said 1.6.5 guides slide internally by the guide supports 1.6.4 for radial displacement of the cutting system 1.7. The 1.6.1 radial motor is supported by the 1.6.2 radial motor support which is fixed to the base 1.8 of the device. Additionally, the radial movement system 1.6 comprises the limit switch support 1.6.8 to limit the movement of the radial movement system 1.6 itself. On the other hand, the cutting system 1.7 comprises the 1.7.1 rotary motor that allows the blade 1.7.2 to be rotated at any angle between 0 ° and 360 ° with hourly and counterclockwise movements, in order to position the blade at the angle necessary to perform the cutting of the ostomy disc 2. Additionally, the cutting system 1.7 comprises the blade holder 1.7.3 and the protective piece 1.7.4. The blade 1.7.2 has a horizontal "V" shape as shown in Figure 8. The combination of said horizontal "V" shape of the blade 1.7.2 together with the protective piece 1.7.4 and the central cover 1.3 has the advantage that it helps guide the ostomy disc towards the cutting part of the blade preventing the ostomy disc 2 from separating from the cutting system 1.7, and therefore from the automatic cutting device of ostomy discs 1 The "V" shape of the blade 1.7.2 is especially advantageous because it allows the ostomy disc to be located at the apex of the "V", and any vertical deviation is limited between the center cap 1.3 and the protective piece 1.7 .4, fixing and preventing the oscillation of the set of components. The protective piece will minimize the risk of accidental injury to the user, and may mean that the device is considered safe in airports and other places of controlled access. The blade can optionally also advance vertically to exert pressure when cutting.
    [0065] Figures 9 and 10 show the same radial movement system 1.6 shown in Figures 6 and 7 but a different cutting system 1.7 in which the engine 1.7.1 is replaced by a bearing 1.12.1 for free rotation of the blade 1.7.2. The blade 1.7.2 is supported at one end of the elongated part 1.12.2 and the other end of the elongated part 1.12.2 is attached to the bearing 1.12.1. Therefore, the blade 1.7.2 has a free and displaced rotation on the axis 1.12.
    [0066] The automatic cutting device for ostomy discs 1 has the electronic system 1.11 to control the angular motor 1.5.1, the radial motor 1.6.1 and the rotary motor 1.7.1. The electronic system 1.11 comprises the microprocessor 1.11.2 to control the motors 1.5.1, 1.6.1 and 1.7.1 and the wireless communication means 1.11.1 to connect to the registration and image processing system 4. That is, the stoma preferably together with elements 3 that serve as reference of the position, inclination and / or size thereof, which must be carried by the ostomized subject in the vicinity of stoma 5, must be captured by the image registration and treatment system 4 which will record the image of stoma 5, It will detect its contour, calculate the coordinates that make up the contour, send said series of coordinates to device 1, these coordinates being received by the wireless communication means 1.11.1 of the electronic system 1.11, which based on those coordinates will calculate an equivalent trajectory to the contour of the stoma and through the microprocessor 1.11.2 it will drive the motors of the angular movement system 1.5, the radial movement system 1.6, and the cutting system 1.7 such that the cutting element 1.7.2 will describe said path on the ostomy disc 2 to proceed with the cutting of the disc.
    [0067] As an orientation, it is possible to manufacture the device of the present invention in polar coordinates with a size of 15 cm in diameter and 5 cm high, so that its surface is even smaller than most ostomy bags.
    [0068] Thanks to the combination of at least the 1.5.1 angular and 1.6.1 radial motors, the device describes the path of the stoma contour on the ostomy disc while the blade makes the cut. The use of the device is very simple by the user. Once a photograph of the stoma (stoma scan) is taken, the stoma contour path converted to polar coordinates is calculated and the information is sent via wireless (Bluetooth or WiFi) to the automatic cutting device 1, the ostomy disc is placed, focusing it thanks to the central axis 1.13 of the automatic cutting device 1.
    [0069] The image registration and processing system 4 (see Fig. 12) can be implemented in an application for mobile telephony terminals ("mobile application"), which comprise sufficient elements (a scanner to register an image of the stoma, a image processor, a processor to execute an image recognition algorithm and WiFi / Bluetooth wireless connection means, ...) to record the stoma image, detect its contour, calculate the coordinates that make up the contour and send the coordinate information to the electronic system 1.11 so that it calculates a path equivalent to contour of the stoma 5 and through the microprocessor 1.11.2 drive the motors of the angular movement system 1.5, the radial movement system 1.6, and optionally the cutting system 1.7 in such a way that the cutting element 1.7.2 describes said path on the ostomy disc 2 to proceed with the cutting of the disc. In case the 1.7 cutting system has the 1.7.1 rotary motor, the 1.11.2 microprocessor will control the 1.7.1 rotary motor. Not so when the cutting system 1.7 has the free rotation axis 1.12.
    [0070] In addition to its scanning function and stoma contour recognition, the mobile application can provide useful information to guide the patient in their day-to-day living with a bag.
    [0071] A more advanced development of the mobile application may also include integration with the healthcare system, with the following advanced features:
    [0072] - Photographs of the stoma and measurements of the perimeter of the stoma could be shared with the therapist, and show their evolution over time, which would facilitate the monitoring and control of the ostomized patient.
    [0073] - Automatic learning algorithms based on image analysis could be implemented, which analyze the evolution of stoma contour, color or texture, to study the evolution of the stoma and detect possible complications as soon as its first signs appear.
    [0074] To carry out the correct stoma measurement, it is necessary to establish "calibration references" which can also be called "calibration labels" or "calibration elements" 3. There are several ways to reference the stoma size so that the mobile application is able to capture the correct coordinates.The preferred way consists of adhesive elements of calibration 3 (see Fig. 11): before registering the image from the mobile application, a series of adhesive calibration elements 3 are placed around the stoma to calculate the exact size and contour of the stoma. These adhesive calibration elements 3 act as a reference of known size and observable inclination, so that an algorithm can calculate the coordinates in real size of each of the stoma contour points.
    [0075] Also, another type of calibration element that can also provide a reference of size and position in the image would be based on a series of laser pointers 7 (or collimated light sources) (see Fig. 13) oriented in the same direction or inclined a certain angle from the device that captures the stoma photograph.
