Description

Esophageal Echocardiography Device and Method with Fluid Control and Image Clarification

[0001] The present invention relates to the field of medical imaging devices, and more particularly to esophageal echocardiography systems configured to improve image quality and operational flexibility. Esophageal echocardiography is widely used for imaging cardiac structures by placing an ultrasonic probe inside the esophagus, allowing close proximity to the heart. However, existing systems face significant limitations related to image clarity, device size, and operational complexity.

[0002] One of the primary challenges in conventional devices is the accumulation of saliva and biological fluids on the ultrasonic sensor surface. This fluid layer creates an interface that interferes with acoustic transmission, leading to reduced image resolution, signal attenuation, and formation of artifacts. In many cases, imaging must be interrupted to remove fluid from the probe surface, which increases procedure time and reduces clinical efficiency. In addition, current devices are often bulky and require both hands for operation, limiting their usability in emergency or mobile conditions.

[0003] The present invention addresses these limitations by providing an integrated system for fluid control, ergonomic operation, and mobility. The device incorporates a combination of mechanical isolation, active suction, and controlled air or gel injection to maintain a clear imaging region. Furthermore, the system includes a compact controller designed for one-handed operation and a modular structure that enables use in fixed, portable, or fully mobile configurations. This combination allows reliable echocardiographic imaging in a wide range of clinical and non-clinical environments.

[0004] The technical field of the above invention is medical equipment and cardiac imaging using esophageal echocardiography, especially with the ability to produce clear images by removing saliva. This claimed invention can be searched through international codes (IPC) and international classified codes (Cooperative patent classification with the abbreviation CPC)), A61B2018 / 00023, A61B8 / 12, A61B18 / 1492, A61B2090 / 3782, A61B2018 / 14, A61B2018 / 0016, A61B18 / 12, A61F7 / 12 and A61B8 / 14 in search engines and international online databases.

In this device, continuous echo operation is possible by using a method of transferring heat to the outside of the imaging environment.

The invention does not disclose any structural modifications to the probe for controlling saliva or biological fluids, and does not include a fluid isolation system such as an annular cuff, suction mechanism, or air or gel injection around the ultrasonic sensor. Furthermore, the invention does not provide a movable or retractable probe head, nor does it include any mobile or wearable control system for performing transesophageal echocardiography.

For example, this invention describes a transesophageal ablation device comprising a flexible probe and a two-dimensional array of transducer elements configured to focus ultrasound energy at a target region within the heart. The method includes inserting the device into the esophagus, positioning the transducer array relative to cardiac tissue, focusing ultrasonic energy to a predetermined location, and delivering high intensity focused ultrasound to form lesions while minimizing damage to surrounding esophageal tissue.

For example, this invention describes a method in which an ultrasound transducer is positioned relative to a patient and emits ultrasound energy that is focused at one or more focal points within target tissue. The method includes positioning the transducer, focusing the ultrasound energy using imaging and location techniques, and ablating the target tissue while minimizing damage to surrounding tissues. In this invention, the focus is on therapeutic ablation using focused ultrasound energy rather than diagnostic imaging or image clarification. The invention does not address challenges related to saliva accumulation or fluid interference on the surface of an ultrasonic sensor, and no fluid control system such as an annular cuff, suction passage, or air or gel injection mechanism is disclosed. Furthermore, the invention does not include a probe configured for transesophageal echocardiography, nor does it disclose any movable or retractable imaging assembly or a mobile or wearable control system for echocardiographic imaging.

[0016] In patent No. JP6549706B2, under the title of "Clutter suppression for synthetic aperture ultrasound", which was registered on 2015-09-28, several devices described herein were claimed which can be used to improve ultrasound imaging quality by reducing artifacts in ultrasound signals. For example, this invention describes an ultrasound processing system configured to receive A-line signal data from an intravascular ultrasound imaging device, perform focusing operations, and apply coherency-based processing to suppress artifacts such as side lobes and grating lobes. The system further includes units for determining phase coherency, adjusting signal data based on coherence thresholds, and compensating the processed signal to improve image quality. In this invention, the focus is on signal processing and artifact suppression within ultrasound data, rather than addressing physical or environmental causes of image degradation. The invention does not disclose any structural modifications to the probe for controlling biological fluids or improving the probe–tissue interface.

For example, this invention describes a catheter comprising an ultrasonic imaging core arranged for both rotational and linear translation within the catheter. The system includes a patient interface module configured to control rotational and translational movement of the imaging core, as well as an ultrasonic energy generator and receiver for producing image data. The system further includes an imaging engine configured to generate images based on received ultrasonic signals. In this invention, the focus is on mechanical control and positioning of an ultrasonic imaging core within a catheter system, rather than addressing image degradation caused by biological fluids. Although the invention includes movable and controllable ultrasonic components, it does not disclose any mechanism for managing saliva or fluid accumulation on the probe surface. Furthermore, no fluid isolation system such as an annular cuff, suction passage, or air or gel injection is provided. The invention is not specifically directed to transesophageal echocardiography, and does not include a mobile or wearable control system or a coordinated fluid–mechanical solution for maintaining a clear imaging interface.

For example, this invention describes an endoesophageal catheter comprising an expandable balloon disposed over the probe head, wherein the balloon is inflated with an acoustically transmitting liquid to improve acoustic coupling between the ultrasound transducer and surrounding tissue. The system includes fluid inflow and outflow lumens for controlling the expansion of the balloon and maintaining the desired acoustic interface during imaging. In this invention, although a balloon-based structure is used in proximity to the ultrasonic probe, the purpose of the expandable member is to enhance acoustic coupling using a liquid medium rather than to isolate or remove biological fluids such as saliva. The invention does not disclose any mechanism for actively removing saliva from the probe surface, nor does it include a suction passage, fluid routing system, or air or gel injection configured to generate a localized separation region. Furthermore, the expandable member is not configured to define separate saliva and imaging regions, and no magnetic valve system or coordinated fluid isolation architecture is disclosed. Additionally, the invention does not include a movable or retractable ultrasonic sensor assembly or a mobile or wearable control system for performing echocardiographic imaging.

For example, this invention describes a robotic workstation configured to control an interventional tool having a cable-driven distal end, wherein motor currents and actuator positions are monitored to estimate and control contact force without the use of dedicated force sensors. The system includes calibration modules for generating lookup tables and force-to-motor current relationships, and an actuation controller configured to provide precise motion and force control of the probe during operation. In this invention, the focus is on robotic control and sensorless force estimation for probe positioning, rather than addressing image degradation caused by saliva or biological fluids.

In particular, no fluid control system such as an annular cuff, suction passage, or air or gel injection is provided. Furthermore, the invention does not address fluid isolation, saliva removal, or the creation of a localized separation region, and does not include a mobile or wearable control configuration as described in the present invention.

[0020] In patent No. US9724119B2, under the title of "Methods of using high intensity focused ultrasound to form an ablated tissue area containing a plurality of lesions", which was registered on 2015-12-02, several devices described herein were claimed which can be used to ablate cardiac tissue using high intensity focused ultrasound (HIFU). For example, this invention describes a transesophageal ablation device comprising a flexible elongate probe and a two-dimensional array of transducer elements configured to focus ultrasound energy at a target region within the heart. The method includes inserting the device into the esophagus, positioning the transducer array relative to cardiac tissue, focusing ultrasonic energy to a predetermined focal zone, and delivering high intensity focused ultrasound to form lesions while minimizing damage to surrounding esophageal tissue. In this invention, the focus is on therapeutic ablation of cardiac tissue rather than diagnostic imaging or image clarification. The invention does not address challenges related to saliva accumulation or fluid interference on the surface of an ultrasonic sensor, and no fluid control system such as an annular cuff, suction passage, or air or gel injection mechanism is disclosed. Furthermore, the invention does not include a movable or retractable ultrasonic imaging assembly configured for imaging purposes, nor does it provide any mobile or wearable control system for echocardiographic imaging.

[0021] In patent No. US20120296204A1, under the title of "Multi-Modality Ultrasound and Radio Frequency System for Imaging Tissue", which was registered on 2008-05-06, several devices described herein were claimed which can be used to characterize and image tissue using a combination of ultrasound and radio frequency (RF) technologies. For example, this invention describes a dual-modality system in which focused ultrasound beams are used to vibrate target tissues while a radio frequency system measures the response of the tissue. The reflected RF signals are processed to analyze sideband frequencies, enabling enhanced tissue characterization and imaging of tumors, lesions, and other structures. In this invention, the focus is on multi-modality signal interaction and advanced tissue characterization techniques, rather than addressing physical limitations related to fluid interference at the probe–tissue interface. The invention does not disclose any structural modification of an ultrasound probe for managing saliva or biological fluids, and no fluid isolation system such as an annular cuff, suction passage, or air or gel injection is provided. Furthermore, the invention does not relate to transesophageal echocardiography probe configurations, nor does it include a movable or retractable probe head or a mobile or wearable control system for echocardiographic imaging.

[0022] The present invention provides a mobile esophageal echocardiography device and associated method configured to improve image clarity, operational efficiency, and usability in various clinical environments. The invention addresses limitations of conventional systems related to fluid interference, bulky structure, and limited mobility.

[0023] In one aspect, the invention comprises a probe having a probe head with an ultrasonic sensor configured to transmit and receive ultrasonic waves for imaging cardiac structures. A fluid control system is arranged near the probe head and includes at least one air or gel outlet configured to create a separation region between the ultrasonic sensor and surrounding tissue. An annular cuff is positioned near the probe head and is configured to expand within the esophagus to limit movement of saliva toward the ultrasonic sensor. A suction system is further provided to remove accumulated saliva and biological fluids, and is connected to a saliva storage tank configured to collect the removed fluids.

[0024] In another aspect, the probe includes a movable ultrasonic sensor assembly and micromotor-driven mechanisms configured to allow adjustment of position and angle of the ultrasonic sensor during imaging. The device further comprises a controller configured for one-handed operation, including control interfaces for adjusting probe movement and imaging parameters.

[0025] In a further aspect, the device is configured to operate in fixed, portable, and mobile modes. In the mobile configuration, the controller, power supply, and display are mounted on the user, enabling use in emergency, bedside, and remote environments. The invention thereby provides a compact, integrated, and efficient echocardiography system with improved image stability and usability.

[0026] In esophageal echocardiography, one of the existing problems is the lack of clarity of images due to excessive saliva secretion and its placement on the surface of the tip of the probe, which occurs for some ages, especially young people.In practical clinical use, continuous secretion of saliva, mucus, and other biological fluids inside the esophagus may accumulate on the ultrasonic emission surface of the probe tip, creating an undesired interface between the ultrasonic sensor and the surrounding tissue. The presence of such fluids may cause scattering, attenuation, reflection artifacts, and loss of acoustic coupling, which significantly reduces the resolution, contrast, and diagnostic reliability of the echocardiographic images. In many cases, the operator is required to interrupt the imaging process in order to remove the accumulated fluid or reposition the probe, which increases the duration of the procedure and may reduce patient safety and comfort, especially during prolonged examinations or repeated diagnostic procedures. This problem is more noticeable in patients with increased salivary reflex, younger individuals, or patients with abnormal oral or esophageal secretions.

[0027] Another problem is the relatively large dimensions of the echo device, even in the portable model, which limits its movement.In currently available esophageal echocardiography systems, the device structure is often bulky and dependent on external consoles, which restricts the ability to perform imaging in mobile, emergency, or non-hospital environments. Also, to use this device, both hands are required for control, which limits the specialist in obtaining echo images. In many existing models, the operator must simultaneously control the probe and adjust imaging parameters using separate control units, which reduces the ability to perform other necessary medical actions during the procedure. In situations such as bedside examination, ambulance transport, intensive care monitoring, or home care, the inability to operate the device with one hand and the dependence on large external equipment significantly reduces the efficiency and practicality of the system. In addition, current probe designs do not provide an effective mechanism for preventing saliva from reaching the ultrasonic sensor surface, nor do they include a reliable method for continuous removal of accumulated fluids during operation, which results in decreased imaging efficiency and increased procedural difficulty. Therefore, there is a need for an improved esophageal echocardiography device capable of maintaining a clean ultrasonic transmission surface, preventing fluid interference, improving mobility, enabling one-handed operation, and allowing reliable imaging in fixed, portable, and fully mobile configurations without interruption caused by saliva accumulation or mechanical limitations of existing devices.

[0028] In the invention of the device and method for image clarification in esophageal echocardiography, the method of using superhydrophobic materials was first investigated, which had a negligible effect on image clarity. In the development of the present invention, different methods for preventing fluid accumulation on the ultrasonic emission surface were examined, including the use of superhydrophobic coatings and nanostructured surface treatments applied to the ultrasonic sensor and surrounding probe head components. Although such materials can reduce adhesion of liquid on dry surfaces, it was observed that when the ultrasonic sensor is placed in a continuously moist environment such as the esophagus, the effectiveness of hydrophobic surfaces alone is limited. Despite the hydrophobicity of the ultrasonic sensor surface, placing this sensor on a liquid surface is effective with this method. However, when the sensor is completely surrounded by liquid or biological secretions, the hydrophobic layer cannot prevent the formation of a fluid film between the sensor and the tissue, which leads to loss of image clarity and unstable acoustic transmission. In the case of being placed in a liquid environment, its efficiency will be greatly reduced and we need a method for draining the liquid. Therefore, the present invention introduces an active fluid-control mechanism in addition to surface treatment, in order to continuously remove saliva and other secretions from the imaging region during operation. This device incorporates a method for continuous evacuation and inflating of air and isolating the upper and lower parts to experience maximum efficiency. By using controlled air injection, suction channels, and structural isolation of the imaging zone, the device is capable of maintaining a relatively dry and stable region around the ultrasonic sensor, thereby improving image quality, reducing artifacts, and allowing continuous echocardiographic imaging without interruption.

[0029] In the mobile model, almost all the equipment is placed on the forearm and hand, and for one or two consecutive echoes, the battery will work without the need for recharging. In the mobile configuration, the majority of the operating components are mounted directly on the forearm and hand of the user so that the device can function without the need for a separate console or external support unit. In this mode, the system is powered by a rechargeable battery capable of supplying sufficient energy for one or more consecutive echocardiography procedures without requiring immediate recharging, thereby allowing use in emergency situations, field conditions, or environments where access to electrical power is limited. The controller (6) is designed in such a way that the user of the device has maximum access to the settings with the least amount of finger movement. The controller (6) is ergonomically designed so that the operator can access the required control functions with minimal finger displacement, allowing precise manipulation of the probe and adjustment of imaging parameters while maintaining a stable hand position. The user's hand (35) is fixed to the controller (6) by mesh straps (15) at the wrist and forearm, and the washable mesh fabric straps (15) are adjusted and fastened to the size of the wrist and forearm with the help of fabric adhesives (17). The user’s hand (35) is secured to the controller (6) by means of mesh straps (15) positioned around the wrist and forearm, which are adjustable according to the size of the user’s arm. These straps are made of washable mesh fabric and are fastened using fabric adhesive fasteners (17), allowing firm fixation while maintaining comfort during prolonged use.

The user’s hand (35) is secured to the controller (6) by means of mesh straps (15) positioned around the wrist and forearm, which are adjustable according to the size of the user’s arm. These straps are made of washable mesh fabric and are fastened using fabric adhesive fasteners (17), allowing firm fixation while maintaining comfort during prolonged use.

[0031] The grooves (20) enable air exchange between the skin of the hand and the outside and reduce the user's hand sweating so that he experiences minimal fatigue during prolonged use. The grooves (20) are formed on the surface of the controller (6) in order to allow air circulation between the user’s hand and the external environment, thereby reducing sweating of the palm and fingers during prolonged operation. This ventilation structure improves comfort and reduces fatigue of the operator, especially during long echocardiography procedures. Also, the rubber mesh plates (13) prevent direct contact with the surface of the controller (6) so that the palm does not sweat. In addition, rubber mesh plates (13) are positioned between the palm and the surface of the controller (6) to prevent direct contact, which further reduces moisture accumulation and increases stability of the grip. On the controller (6), various electronic control keys are visible that make it easy for the user to change different menus. A plurality of electronic control keys are arranged on the controller (6) so that different imaging settings, menus, and probe movements can be adjusted without releasing the hand from the controller. In the example shown, the left key (14) rotates clockwise and counterclockwise and presses inward in one direction to move the probe tip, and the upper key (9) rotates clockwise and counterclockwise in the other direction to move the probe tip. In one embodiment, the left key (14) is configured to rotate clockwise and counterclockwise and can also be pressed inward, allowing movement and angular adjustment of the probe tip in one direction, while the upper key (9) is configured to rotate clockwise and counterclockwise in another direction in order to control movement of the probe tip along a different axis. Also, pressing it inward can be used for other functions. Pressing inward on each key may also activate additional control functions such as confirming commands, storing positions, or activating preset imaging modes. For example, pressing inward on either of the two keys mentioned may be used to record or use memory at the appropriate angle. For example, inward pressing of either key may be used to store the current probe angle in memory or to return to a previously stored position, thereby facilitating rapid repositioning during imaging. The function of the two keys (14) and (9) is like a mouse scroll and has a function similar to the large and small wheels in existing models. The operation of the keys (14) and (9) is similar to a scroll mechanism, comparable to the control wheels used in conventional echocardiography devices, but arranged in a more compact and ergonomic configuration. Key (14) is designed to be used with the right thumb and key (9) is designed to be used with the index finger. Key (14) is positioned so that it can be comfortably operated by the thumb of the right hand, while key (9) is positioned for operation by the index finger, allowing precise control with minimal hand movement.

[0032] Also, key (11) located next to key (9) allows movement and changes in menus, moving forward, backward, and down. Key (11), which is positioned next to key (9), is configured to allow navigation through different menus and control options, including forward, backward, upward, and downward movements within the device interface. The main reason for this design difference is the ability of the user to recognize when working without looking and avoiding unintentional mistakes between the two keys next to each other. The difference in shape, position, and tactile structure of the keys is designed so that the operator can distinguish between them by touch without the need to look at the controller, thereby reducing the possibility of unintended operations during medical procedures. On the right side, the image direction change key (7) is also seen, which can only be used in two positions. On the right side of the controller, an image direction change key (7) is provided, which allows switching between predefined imaging orientations and is configured to operate in limited positions in order to prevent accidental activation. There are a number of status display LEDs (10) and an audio indicator (12) on the controller (6) that make it possible to work without directly viewing the monitor. A plurality of status display LEDs (10) and at least one audio indicator (12) are provided on the controller (6), allowing the operator to receive operational feedback without continuously looking at the monitor. In the case of using a fixed or portable model, if the display is placed at an inappropriate angle to the monitor, these LEDs will show the relative conditions to an acceptable level. When the device is used in the fixed or portable mode and the monitor is not directly visible, the LEDs (10) provide visual indication of device status, imaging condition, and system activity, enabling the operator to continue working without interruption. Also, audio announcements reveal the operation or non-operation of each key and the status of use. The audio indicator (12) provides sound notifications corresponding to activation of keys, changes of mode, warnings, or system status, thereby allowing the operator to confirm correct operation without visual verification. In the case of mobile use, the saliva collection tank (16) will be connected to the controller (6) by the connecting tube (21). In the mobile configuration, the saliva collection tank (16) is connected to the controller (6) through a connecting tube (21), allowing collected saliva to be transferred away from the probe during operation. The battery compartment (18) is also fixed to the controller (6) with the help of a latch (22), a connector (25) and a slider (23). The battery compartment (18) is detachably fixed to the controller (6) by means of a latch (22), an electrical connector (25), and a sliding locking mechanism (23), allowing quick installation or replacement of the battery unit while maintaining secure electrical connection.

[0033] There are two points in this connection. As we know, in the case of mobile use, we need a backup power supply, a separate display, and a saliva tank that can be connected to the controller (6) with a detachable connection. Two important considerations are provided in this connection structure. In the mobile mode of operation, the device requires a backup power supply, a detachable display unit, and a saliva collection tank, all of which must be capable of being connected to and disconnected from the controller (6) in a reliable and hygienic manner. When installing the front of the controller (6), the connector (38) is placed inside the ring (23) and the barbed slider (23) which is in the most open position moves inward along the groove (34) and after connecting to the connector (19) and connecting to the pins (42) enables the transfer of electrical current and information. During installation, the front connector (38) of the controller (6) is positioned inside the ring-shaped guide (23), and the barbed slider (23), which is initially in an open position, moves inward along the groove (34). After engagement with the rear connector (19) and alignment with the electrical pins (42), the system establishes electrical connection and data transmission between the connected parts. The rechargeable battery (24) is held and protected by the composite frame (33) and in the operating mode may generate some heat, which is carried out through the metal surface (28) located under the battery (24) and the air transfer holes (29). The rechargeable battery (24) is mounted inside a composite frame (33) that provides mechanical protection and structural support. During operation, the battery may generate heat, which is dissipated through a metal heat-transfer surface (28) positioned beneath the battery (24), together with air transfer holes (29) that allow ventilation and cooling of the battery compartment.

[0034] Due to the very short distance between the battery (24) and the controller (6), it is almost impossible to transfer air from the upper surface. Because the distance between the battery (24) and the controller (6) is relatively short, natural air circulation from the upper surface is limited, and therefore the cooling structure is designed to transfer heat mainly through the metal surface (28) and the air transfer holes (29) located around the battery compartment. The connection of the monitor (8) to the composite body (33) is made through a ball and socket joint, where the ball (30) is connected to the body and the socket (31) is connected to the monitor (8), and it will provide the user with suitable adjustments in different directions. The monitor (8) is connected to the composite body (33) by means of a ball and socket joint, in which the ball part (30) is fixed to the body and the socket part (31) is attached to the monitor, allowing the monitor to be rotated and adjusted in different directions according to the user’s viewing angle. After the desired adjustment, by tightening the angle retention screw (32), the direction of the monitor (8) relative to the composite base (33) will not be changed. After positioning the monitor at the desired angle, the angle retention screw (32) is tightened so that the relative position of the monitor (8) with respect to the composite body (33) remains fixed during operation. The controller (6) has a connection connector on the front and two connectors on the rear. The controller (6) includes one connector on the front side and at least two connectors on the rear side in order to allow connection of different modules depending on the operating mode. The front connector (38) enables electronic connections through pins (39). The front connector (38) provides electrical and data connection through a set of pins (39) that establish communication between the controller and the connected device. Also, the air injection connector (40) and saliva suction (41) are located in it, which perform a complete function with the connection of the upgraded probe. In addition, the front connector includes an air injection port (40) and a saliva suction port (41), which together provide fluid control functions when the upgraded probe is connected. On the back of the controller (6), data and electricity are transferred from the connector (19) and saliva transfer is done from connector (43). On the rear side of the controller (6), connector (19) is used for transfer of electrical power and data signals, and connector (43) is used for transfer of saliva or other collected fluids toward the storage or external system.

[0035] The sucked saliva which is being discharged from connector (43) by the pump placed inside the controller is transferred to the device by cable / hose (37) in the fixed or portable model, but in the mobile model we need an isolated collection tank (16) which, in addition to being able to hold a suitable amount of saliva, has the ability to be connected and disconnected without transferring microbes. The saliva that is removed through connector (43) by means of a suction pump located inside the controller is transferred through the cable or hose (37) to an external device in the fixed or portable configuration. However, in the mobile configuration, an isolated collection tank (16) is required, which is capable of storing a sufficient volume of saliva and can be connected to or disconnected from the controller without causing contamination or transfer of microorganisms. To achieve this purpose, the tank (16) which is connected to the controller (6) by connecting tube (21) uses the tube (45) for air outlet which extends at the highest level of the tank to the proximity of the saliva inlet tube and is equipped with a semi-permeable filter. For this purpose, the tank (16), which is connected to the controller (6) by the connecting tube (21), is provided with an air outlet tube (45) that extends from the uppermost part of the tank toward the region near the saliva inlet tube, and this air outlet tube is equipped with a semi-permeable filter. This filter allows air to pass through to reduce the fluid pressure inside the tank but does not allow liquids, especially saliva, to pass through so that it is not transferred outside the tank in unwanted movements. The semi-permeable filter allows air to pass in order to equalize pressure inside the tank while preventing liquid, particularly saliva, from escaping, thereby avoiding leakage during movement of the device and maintaining hygienic operation.

[0036] The saliva tank (16) is connected to the device through magnets (44) which are connected to the metal surface (28) And it also allows air to pass through with a very small distance. The saliva tank (16) is detachably connected to the device by means of magnets (44) that are attached to the metal surface (28), allowing the tank to be quickly installed or removed while maintaining stable positioning during operation. The magnetic connection also keeps a small clearance between the tank and the controller surface, which allows limited air circulation and helps reduce heat accumulation. In the upgraded probe (5), to maintain the angle of the fluid transfer tubes and electrical wires in the part that is placed inside the esophagus, there is a kind of hard holder (46) with the ability to withstand force in some directions and the ability to bend in other directions. In the upgraded probe (5), a rigid holder (46) is provided in the portion that is inserted into the esophagus, in order to maintain the correct orientation of the fluid transfer tubes and electrical wires. This holder is designed to resist bending in certain directions while allowing controlled flexibility in other directions, thereby protecting the internal components during insertion and movement of the probe. This part, like the human spine that protects the spinal cord, protects the air and saliva hoses and wires in the relatively vulnerable part. The structure of the holder (46) is similar to a segmented spine, providing both strength and flexibility, so that the air tubes, suction tubes, and electrical wires are protected from excessive bending or damage in the most vulnerable region of the probe. At the tip of this hard holder (46) is also the probe head (2), which also includes the last vertebra of this holder. The probe head (2) is connected to the distal end of the holder (46) and forms the final segment of this protective structure.

[0037] The other retaining nuts (47) are similar and can be bent to some extent by means of hinge joints (48). Additional retaining segments (47) are connected to each other through hinge joints (48), allowing limited bending of the probe while maintaining structural stability. These joints (48) maintain their connection to each other with the help of pins (49). Each hinge joint (48) is secured by pins (49), which ensure mechanical continuity while permitting controlled angular movement. The ultrasonic sensor assembly (50) inside the probe head (2) is movable and moves forward and backward by means of a micromotor (53) connected to the screw (51) by rotating this screw (51) inside the nut (52). The ultrasonic sensor assembly (50) located inside the probe head (2) is movable along the longitudinal direction by means of a micromotor (53), which rotates a screw (51) inside a nut (52), thereby allowing forward and backward displacement of the sensor assembly. This movement and deformation minimize the vulnerability of elderly people or people with sensitive esophagus during insertion and removal of the probe. This adjustable movement allows the probe head to be inserted and removed more safely, especially in elderly patients or patients with sensitive esophageal tissue, by reducing mechanical stress during positioning. After positioning the probe head (2) and opening the annular cuff (3), the ultrasonic sensor assembly (50) is brought out to allow imaging and changing the angle. After the probe head (2) is correctly positioned and the annular cuff (3) is expanded, the ultrasonic sensor assembly (50) is moved outward to the imaging position, allowing proper contact and enabling angular adjustment for image acquisition. The angle of the ultrasonic sensor (59) is changed by two micromotors (55) that are positioned at a 90-degree angle to each other. The angle of the ultrasonic sensor (59) is controlled by at least two micromotors (55) arranged approximately perpendicular to each other, allowing multidirectional adjustment of the emitted ultrasonic waves.

[0038] These direction-changing micromotors (55) maintain their mechanical connection with the spherical housing by means of a rubber ring (56) and collectively provide the appropriate angle for emitting waves when rotating in different directions. The micromotors (55) are connected to a spherical housing through an elastic ring (56), which maintains mechanical stability while allowing rotation in multiple directions, thereby enabling precise orientation of the ultrasonic beam. It was previously stated that the transmission of electrical current and data wires (58) is carried out through the air transmission hose, and the same rule is observed in the ultrasonic sensor, and the connector (57) is used for both air and wires. Electrical wires and data transmission lines (58) are routed together with the air transmission hose, and the connector (57) is configured to allow both fluid passage and electrical connection through a single integrated channel, thereby reducing the number of separate conduits inside the probe. In image preparation, depending on the placement of the ultrasonic sensor (59) inside the esophagus (63), the angle can be changed to obtain the best images. During imaging, the angle of the ultrasonic sensor (59) is adjusted according to its position inside the esophagus (63) in order to obtain the clearest possible view of the cardiac structures. The emitted ultrasonic waves (62) are sent and returned in the required direction. Ultrasonic waves (62) are transmitted and received in the selected direction to produce the desired echocardiographic image. Also, considering the nature of ultrasonic sensors, flexible materials (60) should be used in their connection to the body that do not transmit sensor vibrations to the body. Flexible materials (60) are used between the sensor assembly and the probe body in order to prevent transmission of vibration from the sensor to the probe structure, thereby improving image stability.

[0039] An important point about the annular cuff (3) is that it receives air through a hose and becomes large enough in its place to prevent saliva from passing through and at the same time allow movement. The annular cuff (3) is connected to an air supply hose and can be inflated after placement in the esophagus, so that it expands to block the passage of saliva while still allowing controlled movement of the probe. By increasing the pressure, the excess air goes into the holes (61) and creates air bubbles, which eliminates the need to place two air tubes next to each other. When the pressure inside the cuff increases beyond a predetermined level, excess air is released through the holes (61), creating air bubbles around the probe head and helping to keep the imaging region free of saliva without the need for additional air tubes.

[0040] In some cases, depending on the diagnosis of the treating physician, the cuff (3) used may be transformed from a volume-changing sample by air pressure (3) to a sponge sample (65) so that the probe (5) moves inside the sponge sample (65) instead of moving with the cuff (3) and does not cause damage to the esophagus. In certain medical situations, the cuff (3) may be replaced with a sponge-type cuff (65) instead of an inflatable cuff, so that the probe (5) can move inside the sponge structure while the cuff remains fixed, thereby reducing the risk of injury to the esophageal wall. In this case, the new problem is the guidance of saliva from the probe, which is achieved by placing the magnetic ring (68) and the conductive valves (66) in the probe. In this configuration, saliva control is achieved by providing a magnetic ring (68) and conductive valves (66) inside the probe, which guide the saliva toward the suction path. When the sponge cuff (65) approaches each conductive valve (66), the valve is placed in the open position (69) and saliva is directed into it through the funnel-shaped section above the cuff (67). When the sponge cuff (65) reaches the position of each conductive valve (66), the valve moves to the open position (69), allowing saliva to flow through a funnel-shaped section (67) toward the suction channel.

[0041] In this case, the expanding ring (64) becomes larger with the help of air pressure when entering the patient's throat, and after the cuff (65) is placed in its place, it passes through the cuff (65) with the air pressure decreasing. During insertion, the expanding ring (64) increases in size by air pressure to guide the probe safely through the throat, and after the cuff (65) is positioned, the air pressure is reduced so that the ring can pass through the cuff without causing damage. In the next stage, the probe can pass in two directions, and when exiting, the expanding ring (64) increases in volume with the air pressure, causing the sponge cuff (65) to exit. During removal, the expanding ring (64) is again enlarged by air pressure, allowing the sponge cuff (65) to be safely released and removed together with the probe, thereby preventing injury to the surrounding tissue.

[0042] Providing clearer images than previous models increase the accuracy of diagnosis and treatment. By preventing the accumulation of saliva and other biological fluids on the ultrasonic sensor surface and by providing controlled air injection, suction, and isolation of the imaging region, the device is capable of producing clearer and more stable echocardiographic images compared to conventional devices, thereby increasing the accuracy of diagnosis and improving the reliability of medical decisions. Also, with the mobile model, it is even possible to provide echocardiography at home for people with special conditions such as very high weight or risk of mobility in fractures, etc. Due to the compact structure and the possibility of operating the device in fixed, portable, or fully mobile configurations, echocardiography can be performed in various environments including hospitals, ambulances, home care situations, and locations where conventional large echocardiography systems cannot be used, such as for patients with severe obesity, fractures, limited mobility, or critical conditions that make transportation difficult. The device is easier to move and can be used in ambulances or areas affected by natural disasters. The reduced size and integrated controller structure allow the device to be easily transported and used in emergency situations, ambulances, military or rescue operations, and areas affected by natural disasters where rapid diagnostic imaging is required. Also, this device is useful and usable in patients who have problems with bleeding or other abnormal discharges in the mouth of the upper parts of the esophagus that are above the annular cuff. In addition, because the annular cuff and suction system prevent fluids from reaching the imaging region, the device can be safely used in patients who have bleeding, excessive saliva, or abnormal discharges in the oral cavity or upper esophagus, conditions in which conventional esophageal echocardiography devices may produce unclear images or may not be usable. Furthermore, the ergonomic controller design that allows one-handed operation enables the specialist to perform imaging while simultaneously carrying out other medical procedures, which increases efficiency and reduces procedure time. The combination of fluid control, improved mobility, ergonomic handling, and adjustable probe structure results in a safer, more reliable, and more versatile esophageal echocardiography system compared to existing devices.

[0088] [Fig: 21]: This figure illustrates the upper part of the probe with the cuff fixed on the probe in one embodiment, and with the cuff fixed but slidable in another embodiment. In this figure, the probe is positioned inside the esophagus and the expanding ring and sponge cuff are used to hold the probe in place.

[0089] [Fig: 22]: This figure presents the probe in a configuration in which the probe is slidable inside the cuff together with the expanding ring, shown from two different angles. In this embodiment, the probe is allowed to move relative to the cuff so that the imaging position can be adjusted without removing the probe from the esophagus. The expanding ring maintains the position of the cuff against the inner wall of the esophagus, while the probe slides through the cuff to allow imaging of different parts of the heart. This structure allows stable positioning and controlled movement during the echocardiographic procedure.

In the first view, the expanding ring is in the expanded state. In the second view, the cuff is guided into the esophagus. In the third view, the ring is contracted to allow positioning of the probe. In the fourth view, the echocardiographic imaging procedure is performed while the cuff holds the probe in position. In the final view, the expanding ring is expanded again to allow removal of the sponge cuff from the esophagus. This sequence demonstrates how the probe can be inserted, stabilized, used, and removed safely.

[0092] [Fig: 25]: This figure demonstrates the enlarged view of the valve mechanism located above the cuff, showing the valves in both open and closed positions under the influence of the magnetic ring. In this embodiment, the magnetic ring controls the position of the conductive valves so that the air and saliva paths can be opened or closed as required. This structure prevents saliva from reaching the ultrasonic sensor while allowing air exchange and suction when necessary. The funnel-shaped section directs fluid toward the suction path, ensuring safe operation of the device during echocardiography. The figure includes parts Magnetic Ring (68), and Open Valve Position (69).Examples

[0093] To implement this invention, using component design technology, first the modified and upgraded parts will be manufactured in the field of solid design and then used in field tests. For implementation of the present invention, the modified and upgraded components are first designed using computer-aided design (CAD) and solid modeling technologies, and the designed parts are then manufactured and evaluated through experimental and field-testing procedures. For example, the controller body and probe head are simulated in a 3D design software such as SolidWorks or CATIA and a test sample is made by a 3D printer by preparing a point cloud file. In one embodiment, the controller body, probe head, cuff structure, and internal mechanical components are modeled in three-dimensional design software such as SolidWorks, CATIA, or similar engineering design platforms, and prototype samples are produced using additive manufacturing methods such as three-dimensional printing based on digital model files or point-cloud data. If necessary, changes are made to the dimensions and angles. After producing the initial prototype, dimensional corrections, angle adjustments, and structural modifications are performed based on functional testing results in order to obtain the desired mechanical performance and ergonomic compatibility. After reaching the desired sample, a hard or flexible mold is prepared from the body and made with suitable materials such as resins or metals or composites. When the final geometry is confirmed, molds are prepared for mass production, and the parts are manufactured using suitable materials including medical-grade polymers, resins, metals, or composite materials depending on the mechanical strength, flexibility, and sterilization requirements of each part. The next step is the manufacture of electronic boards, which in component assembly workshops can generally be assembled on the board with the help of an SMD assembly machine. Electronic circuits and control boards required for operation of the device are manufactured separately, and electronic components are mounted using surface-mount technology (SMD) or other automated assembly methods in specialized electronic assembly workshops. In the probe, the assembly of various parts is done manually. Due to the precision required in the probe structure, assembly of the probe head, fluid channels, electrical wires, micromotors, and sensor components is preferably performed manually or with semi-automatic tools under controlled conditions in order to ensure correct alignment and safe operation.

[0094] A notable point in this device is the need to disinfect the parts related to saliva discharge, which will be used in a closed or open circuit with the help of detergent and disinfectant solutions and circulation by the saliva pump of the device. An important aspect of this device is the requirement for proper cleaning and disinfection of the components that are in contact with saliva and other biological fluids. The parts related to saliva discharge, suction channels, and storage tank may be cleaned using a closed or open circulation system in which detergent or disinfectant solutions are passed through the internal fluid paths by means of the saliva pump of the device. An open circuit or increased disinfectant concentration is more recommended, as the consumed liquids are removed after passing through the device and transferred to the sewer. In one embodiment, an open circulation mode is used in which the cleaning liquid passes through the device and is discharged after use, thereby preventing contamination of the internal system. In another embodiment, a closed circulation mode may be used for repeated washing when appropriate. Increasing the concentration of disinfectant solution may be preferred in situations requiring higher sterilization level, especially when the device has been used for patients with infectious conditions. The design of the fluid path allows complete drainage of the cleaning liquid so that no residue remains inside the device after disinfection.The materials used in the probe, tubes, valves, and storage tank are selected so that they can withstand repeated cleaning, disinfectant solutions, and sterilization processes without loss of mechanical strength or functional performance, thereby allowing safe reuse of the device in medical environments.

[0095] The present invention is applicable in the field of medical imaging equipment, particularly in esophageal echocardiography devices used for diagnosis, monitoring, and treatment planning of cardiac and vascular conditions. The device can be manufactured using conventional mechanical, electronic, and medical device production technologies, including computer-aided design, precision machining, polymer molding, composite fabrication, and electronic board assembly, and therefore can be industrially produced without requiring unusual manufacturing methods. The invention can be used in hospitals, diagnostic centers, emergency units, ambulances, intensive care units, home care services, and disaster or field medical operations where conventional echocardiography systems may be difficult to use due to size or mobility limitations. Because the device includes a fluid isolation system, suction mechanism, ergonomic controller, and mobile configuration, it can be safely applied in patients with excessive saliva, bleeding, or abnormal secretions in the oral cavity or esophagus, where existing devices may produce unclear images. The invention is also suitable for repeated clinical use because the fluid paths, probe components, and storage tank are designed to allow cleaning and disinfection using standard medical sterilization procedures. Therefore, the present invention has clear industrial applicability in the manufacture and use of medical diagnostic equipment and can be widely used in healthcare systems, emergency services, and mobile medical units.
