Abstract

The present invention relates to a device for supporting probe and / or endoscope parts of medical devices introduced through the mouth of a patient.

Description

[0001] A device for supporting probe and / or endoscope parts of medical devices introduced through the mouth of a patient

[0002] Technical field of the invention

[0003] The present invention relates to medical probes or endoscopes, and more specifically to supporting equipment for use with such medical devices.

[0004] Background of the Invention

[0005] Many different medical procedures and examinations are performed using probes and endoscopes introduced through the patient’s mouth. These include ultrasonic probes and various types of endoscopes, such as bronchoscopes, laryngoscopes, and gastroscopes. These procedures are often highly uncomfortable for the patient, which is why sedation is commonly used. Sedation helps patients tolerate the procedure rather than actively resist it, allowing medical staff to carry it out with fewer disturbances.

[0006] However, even under sedation or general anesthesia, involuntary muscular reactions and reflexes, especially in the esophagus, can make precise control of the equipment difficult. Rather than the challenge being in the initial insertion, it is the ongoing task of maintaining precise placement that is problematic. For instance, patients may fail to swallow as instructed or may exhibit esophageal peristalsis and muscle tension that interfere with fine manipulation of the inserted device.

[0007] A key example is transesophageal echocardiography (TEE), used during heart valve repair procedures. The success of such operations depends heavily on the ultrasound operator’s ability to obtain clear and timely images. Unfortunately, the esophagus cannot be fully anesthetized, even under general anesthesia, and its constant movement tends to displace the ultrasound probe. The operator must manually counteract these forces to hold the probe in place while simultaneously manipulating the probe head and controlling the ultrasound system’s interface.

[0008] Another example is performing a biopsy in the esophagus using a gastroscope. Here, unintentional esophageal movements complicate targeting and sampling from the exact tissue of interest, making the procedure technically challenging.

[0009] These examples highlight the need to reduce the manual burden on operators and improve precision during procedures involving esophageal access.

[0010] Summary of the invention

[0011] Thus, it is an object of the present invention to provide a simple solution that solves the above-mentioned problems.

[0012] The present invention provides a novel and practical way of supporting probe and / or endoscope parts of medical devices that are introduced through the mouth of a patient. The device is designed to simplify the handling of such instruments by enabling a single operator to maintain control over the probe or endoscope without needing to interrupt the procedure to reposition or readjust its tip. As a result, the total operating or surveying time may be reduced, thereby lowering the risk associated with the procedure. The device also contributes to improved ergonomics, greater efficiency, and reduced frustration for the medical operator.

[0013] First aspect

[0014] According to a first aspect, the invention relates to a device adapted for supporting probe and / or endoscope parts of medical devices introduced through the mouth of a patient. The device comprises:

[0015] - a first channel part adapted for fitting into the lumen of a bite block for probe and endoscope equipment, or configured as a bite block for probe and endoscope equipment;

[0016] - a second channel part comprising a first wall section adapted for moving between a first position and a second position; and

[0017] - a mechanism adapted for displacing said first wall section between its first and second positions; wherein the first channel part and the second channel part are arranged in extension of each other, being aligned along a common longitudinal axis, and together define a common first channel adapted for supporting probe and / or endoscope parts of medical devices introduced through the mouth of a patient.

[0018] In preferred embodiments, the second channel part, when the first wall section is in its second position, is adapted to prevent a probe and / or endoscope part from being moved through the first channel, while still allowing for rotational motion of said probe and / or endoscope part about its longitudinal axis. This enables the operator to fix the axial position of the probe or endoscope while still permitting fine rotational adjustments during a procedure.

[0019] In a particularly advantageous embodiment, the first channel part is configured to define a second channel arranged parallel to the first channel. This second channel provides separate access for introducing other tools, such as a laryngoscope, suction device, or oropharyngeal airway, which are often required during intubation, endoscopy, or other airway-related procedures.

[0020] The mechanism for moving the first wall section may comprise a pull wire system, optionally including a locking mechanism to retain the wall section in either the first or second position. In some embodiments, the pull wire is actuated via a lever arm or pull rod and may incorporate a spring element to provide resiliency and restore the wall section to its initial configuration when tension is released. The present invention may also extend to a medical device comprising the above-described support device as an integrated or attachable component.

[0032] Detailed description of the invention

[0033] Background on bite blocks and airway access needs

[0034] A bite block is often a single-use medical device used to keep the mouth open during invasive imaging procedures or endoscopy to prevent the patient from biting the probe or endoscope. Bite blocks are generally characterized by the following structural features. A tubular body whose internal lumen serves as the channel for passage of the probe or endoscope, and whose top and bottom outer surfaces serve as the surfaces upon which the subject’s teeth bite. These surfaces are generally flattened. A wall centrally connected to the outer end of the tubular body, shaped such that it should lie comfortably outside and around the subject’s mouth. It is this wall that fulfils the double function of providing a general alignment direction to the tubular body and of preventing the bite block from falling into the mouth. The wall is also known as the front plate. Optionally, a band connected to the bite block and used to strap the bite block firmly to the subject. Some bite blocks are made of a relatively softer plastic material than others, thereby making a better fit within the oral cavity, such that a strap or band is superfluous.

[0035] Preferably, when the first wall section is in its second position, the second channel part is adapted to prevent a probe and / or endoscope part from being moved through the first channel, preferably while still allowing for rotational motion of said probe and / or endoscope part about a longitudinal axis of said probe and / or endoscope part.

[0036] Preferably, when the first wall section is in its second position, the first channel part defines a second channel arranged parallel to the first channel.

[0037] Preferably, the first channel part is configured to define a second channel arranged parallel to the first channel.

[0038] A separate access channel, i.e., the second channel, is important for situations where tools need to be introduced into the oral cavity of a patient during anesthesia. The primary tool is the laryngoscope. This instrument, consisting of a handle and a blade, is inserted into the mouth to provide a clear view of the vocal cords by lifting the epiglottis. This visualization is essential for the accurate placement of the endotracheal tube. The endotracheal tube is a flexible tube inserted through the mouth into the trachea, maintaining an open airway and allowing for mechanical ventilation. The tube’s cuff can be inflated to seal the trachea and prevent air leaks.

[0039] Oropharyngeal airways are also frequently used. These curved devices are inserted into the mouth to keep the tongue from obstructing the pharynx, thereby maintaining airway patency, especially in unconscious patients. Finally, suction devices may be needed for clearing the oral cavity of secretions, blood, or other fluids that could obstruct the airway.

[0040] The need for a secondary access channel integrated with or adjacent to the probe-supporting channel is therefore clear, particularly in emergency and anesthesia settings where multiple instruments must be inserted concurrently. The present invention addresses this need by providing such a dual-channel configuration within a stable, ergonomic structure.

[0041] Channel parts and constriction mechanism

[0042] The invention includes a first channel configured to support endoscopic or probetype medical devices and a second channel arranged in parallel to the first. This dual-channel configuration enables simultaneous introduction of additional instruments, such as laryngoscopes, suction catheters, or oropharyngeal airways. The second channel is formed integrally with or adjacent to the first channel part, and its alignment parallel to the first channel ensures both ergonomic access and spatial separation of instruments. This design allows concurrent use of multiple tools in the oral cavity without interference, supporting advanced airway management procedures or diagnostic interventions where flexible and unobstructed access is critical.

[0043] The device according to the present invention comprises a first channel part either adapted for fitting into the lumen of a bite block for probe and endoscope equipment or configured as a bite block for probe and endoscope equipment. In the latter embodiment, the first channel part may be releasably attached to the device, such as to a second channel part, or a support plate holding the second channel part. The first channel part may thus be for one-time use, i.e., disposable.

[0044] A second channel part is provided with a wall section adapted for moving between a first position to a second position. This function allows the user to fix probe and / or endoscope parts of medical devices extending through the second channel part and into the mouth of a patient, thereby preventing it from being displaced. The first and second channel parts are connected, e.g., via a support plate for holding other components of the device, such as the mechanism adapted for displacing the second channel part’s wall section between its first retracted position and second extended position. Alternatively, the first and second channel parts are made / formed in one piece, e.g., molded as one piece in a polymeric material.

[0045] In one or more embodiments, the first channel part is configured for fitting into the cavity of a bite block for probe and endoscope equipment. The first channel part may comprise two separate insert parts configured for fitting into the cavity of a bite block for probe and endoscope equipment. Alternatively, the first channel part may comprise one or more slits, thereby allowing for press fit assembly with the cavity of a bite block.

[0046] The device features an integrated channel component, i.e., the first wall section, designed to facilitate the controlled constriction of the first channel’s internal passage. The constriction mechanism preferably comprises a pull wire mechanism, actuated by an actuation unit. In one configuration, the first wall section is configured as a lever arm operably connected to the wire, preferably incorporating a spring element, providing resiliency. Alternatively, the first wall section is made of an elastically deformable material with the wire attached directly to the tip of the wall, rather than to the end of a lever arm.

[0047] The inside of the first channel, such as a part of the first wall section, may feature small protrusions, or ribs, to provide better grip on a tool inserted into the first channel. When the actuation unit engages, the user pulls the wire, either causing the lever-like first wall section to pivot and apply a compressive force or directly deforming the elastically flexible first wall section, thereby reducing the first channel’s diameter. The spring element or the elastic deformability of the first wall section ensures that the first channel can return to its original shape when the tension is released, enabling precise modulation of the first channel’s cross- sectional area for variable control.

[0048] In one or more embodiments, the mechanism adapted for displacing said first wall section between its first position and second position comprises a pull wire mechanism. Preferably, the pull wire mechanism comprises a wire with a first end and a second end, wherein the first end of the wire is mounted to the first wall section and wherein the second end is mounted to an actuator.

[0049] In one or more embodiments, the actuator comprises a lever arm hingedly mounted to a mounting bracket.

[0050] In one or more embodiments, the actuator comprises a pull rod mounted to a guide block, which moves linearly within a guide housing.

[0051] In one or more embodiments, the first channel part and the second channel part share a common second wall section. This configuration allows for more stability in the construct.

[0052] In one or more embodiments, the mechanism adapted for displacing the first wall section between its first position and second position comprises a spring element adapted for providing resiliency to the first wall section.

[0053] In one or more embodiments, the first wall section is configured as a lever arm operably connected to the wire.

[0054] In one or more embodiments, the second channel part further comprises a second wall section attached to (e.g., directly, or indirectly via a hinge) a first end of the first wall section, wherein the first wall section comprises a second opposite free end, and wherein the wire is attached to the second opposite free end of the first wall section. Preferably, the first wall section is made of an elastically deformable material, such as a polymeric material.

[0055] It may be necessary for the operator of the probe or endoscope to rotate or turn the probe or endoscope around its longitudinal axis, e.g., to obtain a better position for their tip. To be able to rotate (around its longitudinal axis) and still fix (in the longitudinal direction) the probe and / or endoscope parts extending through the second channel part and into the mouth of a patient, the first channel may further comprise one or more ridges, rollers, or ball bearings formed in the second channel part.

[0056] Sensor-based feedback mechanisms

[0057] In some embodiments, the device may incorporate one or more sensors adapted to detect physical displacement or force applied by the probe or endoscope. For example, a pressure sensor may be positioned in contact with the wall section to detect when axial motion is attempted while the wall is in its second position. Alternatively, an optical or magnetic sensor could detect the rotation or movement of the probe within the first channel. The output of such sensors may be used to provide haptic, visual, or electronic feedback to the user or an external monitoring system. In some embodiments, such sensors could be integrated into a digital display or user interface, allowing the operator to observe real-time positioning data, helping reduce procedural errors and enhancing control.

[0058] Manual release or override mechanism

[0059] For safety and rapid disengagement, the device may include a manual release system configured to override the constriction mechanism. This may be embodied as a spring-loaded trigger, button, or lever that, when activated, returns the first wall section to its retracted position regardless of the actuator’s current state. This feature is particularly advantageous in emergency situations requiring immediate repositioning or withdrawal of the instrument. The release mechanism may be positioned within reach of the operator’s thumb or index finger, enabling one-handed control while maintaining grip on the instrument or associated structure.

[0060] Removable sterile insert

[0061] To enhance hygiene and reduce cross-contamination, the interior of the first channel may be lined with a removable, disposable sterile insert or sleeve. This component may be formed of a thin, flexible polymer and sized to fit snugly within the channel without obstructing functionality. After each use, the insert may be removed and discarded, allowing the core device to be reused under sterile conditions. Optionally, the insert may include integrated features, such as color coding for size indication or molded gripping structures to support various probe types.

[0062] Optical and illumination support

[0063] In more advanced embodiments, the device may include channels or guides for fiber optics, LED elements, or camera mounts. These components may assist in visualizing internal anatomy during endoscopy or intubation. Light-conductive materials may be embedded in the device housing or integrated into the channel walls. In some embodiments, the illumination components may be activated via external switches or triggered automatically when a probe is inserted, thus improving workflow efficiency in low-light or emergency conditions.

[0064] Angled or curved channel variants

[0065] While most embodiments described above assume a linear alignment of the first and second channel parts, alternate configurations are also contemplated. For example, the device may be formed with a pre-defined curvature or angled connection to accommodate unique patient anatomies or specific procedural access angles. Such variants may offer improved ergonomics and maneuverability during complex procedures. In one embodiment, the angle between the channel parts may be adjustable via a hinged joint or flexible segment, allowing the operator to tailor the device configuration dynamically during use.

[0066] A second aspect relates to a medical device comprising a device according to the present invention.

[0067] It should be noted that embodiments and features described in the context of one of the aspects of the present invention also apply to the other aspects of the invention.

[0068] The following examples are not meant to be limiting for the scope of the invention but are merely present to show possible and preferred embodiments of the present invention.

[0069] General description and operational examples

[0070] In the present context, the term “in general,” when used in connection with a feature relating to the present invention, should be understood to mean that the feature may be used with all embodiments of the invention, even if mentioned only in a specific part of the detailed description.

[0071] Typically, the device 100 is adapted to provide support for endoscope and / or probe parts of medical devices extending into the mouth of a patient. The device is generally configured with a first channel 130 for this purpose, and a second channel 140 arranged parallel to the first channel 130, e.g., to allow for the introduction of a laryngoscope or other tool into the oral cavity of a patient during anesthesia while an endoscope or probe remains in place. This dual-channel configuration significantly enhances procedural flexibility, allowing the operator to perform multiple critical interventions without removing or disturbing previously inserted devices. According to the embodiments shown in Figures 1-4, the device 100 comprises a first channel part 1 10 and a second channel part 120 arranged in extension of each other, such that they together define the first channel 130. The first channel part 1 10 is illustrated as being configured to fit into the lumen 22 of a bite block 20 (see Figure 6) but could alternatively be formed integrally as a bite block for endoscope and / or probe equipment. The second channel part 120 comprises a first wall section 122 that is adapted to move between a first position A and a second position B, as shown in Figures 1 A-4B.

[0072] A mechanism is provided for displacing the first wall section 122 between its first and second positions. In the illustrated embodiments, this mechanism comprises a pull wire mechanism including a wire 160 with a first end mounted to the first wall section 122 and a second end mounted to an actuator 150. Two actuator embodiments are provided, shown in Figures 6 and 7. When the first wall section 122 is in the second position B, the second channel part 120 is adapted to prevent axial movement of the endoscope and / or probe through the first channel 130, while still allowing for rotational movement about its longitudinal axis. This configuration enables the operator to lock the device in place without limiting rotational adjustments, a critical feature for optimal maneuverability during procedures.

[0073] The first channel part 110 further defines the second channel 140, which is arranged parallel to the first channel 130. This parallel arrangement allows for simultaneous accommodation of another instrument, such as a suction catheter or a laryngoscope blade, thereby enhancing the device’s utility in complex interventions.

[0074] Optionally, the pull wire mechanism may comprise a locking mechanism for holding the wire in a fixed position, e.g., locking the first wall section 122 in either the open or closed state until manually released by the user. Such a locking feature may be implemented using a mechanical catch, ratchet, or friction-based detent, ensuring secure operation even in dynamic environments.

[0075] Figures 1 and 2 depict a device in an open configuration (first wall section 122 in position A) and a closed configuration (position B), respectively. In this embodiment, the first wall section 122 is constructed as a lever arm operably connected to the wire 160. The second wall section 125 includes a guide pin 129, and the first wall section 122 includes a guide recess 128 adapted to receive the guide pin. These features ensure reliable and repeatable motion by constraining the path of the wall section. In alternative embodiments, the roles of pin and recess may be reversed. These elements cooperate to guide the movement of the first wall section 122 between its two positions. A spring element (not shown) may optionally provide resiliency, biasing the wall section toward one of the positions, which simplifies reset operations and improves user efficiency.

[0076] In general, the device includes a constriction mechanism comprising a first wall section 122 configured to move between an open (A) and a closed (B) position, thereby modulating the internal diameter of the first channel 130. In one embodiment, the first wall section is designed as a lever arm with one end fixed to a pivot or hinge and the other end connected to a pull wire 160. Actuation of the wire, typically by an actuator located outside the oral cavity, causes the lever arm to pivot inward, constricting the channel and immobilizing any device within it. A spring element may be used to bias the wall section toward its open position, providing passive reopening upon release of tension. This configuration ensures reversible, controlled constriction suitable for delicate probe fixation.

[0077] Figures 3 and 4 illustrate a second embodiment of the device. In this version, the second channel part 120 includes a second wall section 125 connected to a first end 123 of the first wall section 122. The opposite free end 124 of the first wall section is attached to the wire 160. The first wall section 122 is made from an elastically deformable material, such as a polymer, enabling it to flex between the open and closed positions. The second wall section 125 also includes a guide recess 127 that supports and guides the wire 160 during operation. This flexible configuration allows for smooth, quiet operation without relying on rigid mechanical joints, making it suitable for sensitive procedures.

[0078] In an alternate embodiment, the first wall section 122 is formed from an elastically deformable polymeric material. The pull wire 160 is connected directly to the free end of this wall section. Upon actuation, the wire pulls the tip inward, deforming the wall and reducing the channel’s diameter. When tension is released, the material’s inherent elasticity restores the original shape, allowing the probe or endoscope to be repositioned or removed. This configuration offers a low-friction, noiseless alternative to hinged systems, favoring minimally invasive or pediatric applications.

[0079] In both embodiments, the first channel 130 may include ridges 126, formed in the second channel part 120, to enhance grip on the inserted endoscope or probe. These ridges may be shaped with shallow profiles to maintain rotational freedom while still providing longitudinal fixation. In alternative designs, rollers or frictionenhancing coatings could serve a similar purpose.

[0080] As shown in Figure 6, one actuator embodiment includes a lever arm 153 hingedly mounted to a mounting bracket 152. The bracket may be removably attached to an endoscope, probe, or auxiliary structure. A ring pull 154 at the end of the lever allows single-finger actuation. Pulling the ring pivots the lever, translating the user’s motion into tension in the wire 160. The other end of the wire is connected to the first wall section 122, resulting in displacement toward the second position B. Releasing the ring allows the lever to return to its initial position (optionally aided by a spring), thereby releasing tension in the wire and allowing the first wall section to return to position A. This mechanism provides immediate tactile feedback and is particularly useful in environments where precision, speed, and dexterity are required — such as in endoscopic operating rooms or emergency settings.

[0081] Thus, the lever-based actuator allows intuitive, precise control with minimal effort by converting small finger motions into a reliable mechanical action via leverage and tension. The actuator design ensures fast engagement and disengagement without requiring both hands, improving workflow and reducing fatigue.

[0082] An alternative actuator is illustrated in Figure 7. This embodiment includes a pull rod 156 connected to a guide block 157 that travels linearly within a guide housing 155. One end of the wire 160 is attached to the guide block 157, and the other to the first wall section 122. The guide housing 155, which may be mounted to an endoscope or other support, ensures constrained linear travel of the guide block. The pull rod 156 extends from the guide housing, providing a grip for the user. A portion of the housing may form a guide tube 158 to ensure alignment and structural integrity during repeated operation.

[0083] When the pull rod is actuated, the guide block moves linearly, increasing wire tension and displacing the first wall section 122 into the second position. This mechanism allows for controlled, consistent force application, which is particularly advantageous for delicate adjustments during diagnostic or interventional procedures. Returning the pull rod to its original position reverses the process, reducing wire tension and allowing the first wall section to revert to the open configuration.

[0084] The linear actuator configuration provides high precision and ergonomic operation, ensuring minimal energy loss and reliable mechanical performance during repeated use. Its low-profile design makes it especially suitable for integration into tight or restricted spaces on surgical consoles or imaging platforms, and it may also accommodate digital augmentation such as haptic feedback or force sensing in future adaptations. Alternative actuator embodiment with integrated trigger mechanism

[0085] In another actuator embodiment, the guide housing 155 (see Figure 10) is configured with a specially shaped guide recess 170 designed to direct and lock a guide pin 181 (see Figure 11 ) connected to a sliding guide block 157. The guide recess 170 may take the form of a letter "L", consisting of a primary longitudinal channel 171 and a secondary transverse locking segment 172.

[0086] During operation, the guide pin 181 mounted on the guide block 157 initially travels along a longer, vertical section (e.g., 171 ) of the guide recess 170. This motion enables linear translation of the guide block 157, which is connected to the pull wire 160. As the guide block 157 slides backward, it increases tension in the wire 160, thereby actuating the pivoting mechanism within the device and moving the first wall section into its second position.

[0087] To secure the device in an actuated state without requiring continuous manual force, the guide pin 181 can be redirected into a shorter, transverse segment (e.g., 172) of the guide recess 170. This secondary segment may include a curved portion that mechanically retains the pin 181 via a lateral shift, thereby locking the guide block 157 in place and maintaining consistent tension in the pull wire 160.

[0088] This locking configuration enhances usability by enabling one-handed operation and secure probe fixation, while also allowing quick disengagement when required. It further contributes to procedural efficiency by reducing unintentional release or drift of the endoscopic or probe equipment.

[0089] To ensure stable attachment of the actuator to the medical device, this embodiment also includes a strap mechanism 190 integrated with the guide housing 155. The strap 190 may be designed to securely fasten the actuator 150 to the handle of an ultrasound probe or similar instrument (not shown). This stabilizing feature prevents unwanted shifting or detachment during use and supports ergonomic operation.

[0090] This actuator mechanism thus combines intuitive motion control with mechanical reliability, expanding the versatility of the device while preserving its core functional goals.

[0091] Wire tube with snap-on clips for secure routing

[0092] To protect the pull wire 160 and ensure smooth operation (see Figures 8 and 10), the wire 160 may be routed through a dedicated wire tube 162 that extends from the actuator mechanism 150 to the pivoted device part 110, 120. This wire tube 162 serves a dual purpose: it acts as a protective sheath that prevents the wire from tangling, kinking, or being accidentally displaced, and it provides structural guidance for consistent force transmission during actuation.

[0093] The wire tube 162 may be equipped with snap-on clips 164 that allow it to be securely attached to the probe, typically along the handle or shaft of an ultrasound probe. These clips 164 ensure that the wire tube follows the contour of the probe closely, preventing it from hanging freely or becoming entangled with other instruments or surrounding equipment during a medical procedure.

[0094] This guided and clipped configuration enhances both safety and ergonomics. It minimizes operator distraction, supports reliable mechanical actuation, and contributes to a clean, organized working environment. By preventing uncontrolled movement of the wire, the snap-on system ensures that the mechanical interface between actuator and device remains stable throughout use.

[0095] Embodiment of device with forceps-like pivoting channel structure

[0096] In general, the device may alternatively be configured as a forceps-like structure (see Figures 9A and 9B) comprising first 110 and second 120 channel parts, each forming a shank. These shanks are pivotally connected at a fulcrum 115 and shaped to define a continuous first channel 130. When actuated by a pull wire 160 connected to one shank, the two parts pivot toward one another, reducing the first channel’s cross-section. The pivoting action is mechanically robust and suitable for materials that lack intrinsic elasticity. In this embodiment, a wall portion 112 of the first channel part’s wall extends adjacent to the pivoting path of the first wall section 122, offering a stable constraining surface for precise channel closure.

[0097] The forceps-like architecture mirrors the functional principles disclosed in Figures 1 and 2. The device 100 is illustrated in an open configuration in Figure 9A, where the first wall section 122 is in its first position A, allowing a probe or endoscope (not shown) to pass freely through the first channel 130.

[0098] The first wall section 122 is formed as part of one of the shanks, enabling it to pivot relative to the opposing wall portion 112 when actuated. The shank associated with the wall portion 112 is here shown including a guide channel 114 that routes the pull wire (not shown in this figure). The wire is fixed to the shank associated with the first wall section 122. When tension is applied, e.g., through an external actuator 150, the wire pulls the first shank toward the second, causing the first wall section 122 to pivot inward and constrict the channel 130. This motion brings the first wall section 122 into its second position B (see Figure 9B), thereby securing the inserted probe or endoscope within the channel. Upon release, the device returns to its open state.

[0099] This configuration offers a mechanically robust and reliable constriction mechanism using pivot-based leverage. It preserves the core advantages of the invention, namely fixation of an inserted device while permitting rotational freedom, while allowing for straightforward manufacturing using rigid materials. Additionally, this embodiment is compatible with a second channel 140 arranged in parallel to the first channel 130, maintaining support for concurrent instrumentation, such as laryngoscopes or suction devices. The pivot-based forceps structure enables precise control with high retention force, making this embodiment well-suited for a range of clinical applications.

[0100] In this embodiment, the wall portion 112 of the wall from the first channel part 110 extends upward and lies adjacent to the pivoting path of the first wall section 122 of the second channel part 120. When the first wall section 122 pivots into its second position B, it slides past the side of this extended wall section 112. This structural relationship enhances the channel constriction by creating a firm, lateral boundary against which the pivoting wall can press. The design improves gripping stability on the inserted probe or endoscope and helps maintain axial alignment within the channel.

[0101] Integrated return spring for passive reopening

[0102] In a refinement of the pivoting channel device, a return spring 195 (see Figures 9A and 9B. Please note that the spring is not correctly depicted in Figure 9B) is integrated between the opposing shanks of the forceps-like structure. This spring 195 is positioned to urge the shanks apart, such that the first wall section 122 is passively returned to its first position A when wire tension is released.

[0103] The return spring 195 ensures automatic reopening of the first channel 130, reducing the need for complex manual intervention. This passive mechanism is especially useful during dynamic medical procedures where rapid repositioning of a probe or endoscope is necessary.

[0104] The spring 195 may be implemented as a coil, torsion, or leaf spring located at or near the fulcrum 115 between the first 110 and second 120 channel parts. Its placement is optimized to maintain consistent opening force without obstructing the movement of the wall sections or interfering with the routing of the pull wire. By restoring the channel 130 to its open configuration immediately after actuation, the integrated return spring 195 enhances usability, safety, and operator efficiency.
