Description

Technical Field

[0001] This utility model patent relates to the field of medical devices, and in particular to a visually adjustable medical flexible endoscope. Background Technology

[0002] Laryngeal masks are suitable for maintaining airway control during short-term routine anesthesia in fasted patients, as well as for airway management with known or unknown difficulties. They can also be used to establish a clean airway during the resuscitation of deeply comatose patients at risk of airway obstruction who may require artificial ventilation. Laryngeal mask ventilation is more reliable, simple to learn, well-tolerated by patients, and has a low incidence of postoperative complications; therefore, it is widely used.

[0003] However, early laryngeal masks lacked visual functionality. During insertion and use, additional tools, such as rigid or flexible endoscopes, were required to observe and confirm the mask's accurate placement, ensuring safety and effectiveness. Subsequently, intubation-type laryngeal masks with wired video capabilities were developed. These masks achieved visual functionality by permanently attaching an imaging element to the mask. For example, patent application CN201810124111.1 provides an improved visual laryngeal mask. This mask extends a camera cavity longitudinally along the inner wall of the ventilation tube and houses a camera device within the cavity, adding visual imaging capabilities to the standard laryngeal mask. This allows for guidance during insertion and real-time observation, monitoring, and adjustment, improving the ease of use and success rate for doctors. However, the camera device of the aforementioned video laryngeal mask airway is mounted on one side wall of the inner wall of the mounting base. The angle and position of the camera are not directly facing the front end of the laryngeal mask airway. Therefore, the observed images of the glottis and esophageal opening are not oriented forward, and the field of view is limited. During monitoring, the condition of the glottis and esophageal opening cannot be clearly observed, and it is impossible to determine whether the tip of the laryngeal mask airway has entered the esophageal opening. Moreover, as the surgery progresses, the position of the laryngeal mask airway may shift, causing the camera to be out of alignment with the glottis. This makes it impossible to detect airway stenosis in a timely manner, and the fixed field of view of the camera prevents timely adjustment of the laryngeal mask airway position.

[0004] Another invention patent application, CN201910107668.9, discloses a laryngeal mask airway and its imaging device. The imaging device includes a housing, a display, an image tube, a light source assembly, a transmission assembly, and an operating handle. The transmission assembly is installed within a control cavity. The proximal end of the image tube extends into the control cavity and is driven and connected to the transmission assembly. The operating handle extends from outside the housing into the control cavity and is driven and connected to the transmission assembly. The operating handle drives the transmission assembly, thereby driving the distal end of the image tube to bend and return to its original position. However, this imaging device cannot maintain a fixed bending angle after the distal end of the image tube is bent by the operating handle. Once the operating handle is released, the image tube returns to its original position. The doctor must hold the operating handle continuously, which affects other surgical operations and can cause fatigue due to prolonged handling. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] The features and exemplary embodiments of various aspects of this utility model patent will be described in detail below. To make the purpose, technical solution, and advantages of this utility model patent clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are configured only to explain this utility model patent and are not configured to limit this utility model patent. For those skilled in the art, this utility model patent can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this utility model patent by illustrating examples of it.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0033] In this invention, "front end" and "rear end" refer to the end of the visually adjustable medical flexible endoscope inserted into the patient's mouth, while "rear end" and "proximal end" refer to the end that is close to the doctor's grip or operation.

[0034] See Figures 1 to 5 The diagram illustrates a structural design of an embodiment of a visually adjustable flexible medical endoscope 10. From distal to proximal, it comprises a camera 1, a support tube 2, and a control module 3. The camera 1 is preferably a high-definition CCD camera located at the distal end of the support tube 2. The control module 3 is located at the proximal end of the support tube 2. The control module 3 controls the bending of the front end of the support tube 2 upwards or downwards, or possibly to the left or right; the bending direction is not limited. This allows the camera 1 to capture images from different angles at its front end. The image data is transmitted via wired or wireless means to a display device (not shown) at the proximal end, enabling doctors to observe the front end of the flexible medical endoscope 10 and the surrounding tissues, such as the position of the glottis, the size of its opening and closing, and the presence of sputum or other contents, allowing for timely intervention.

[0035] Furthermore, the aforementioned support tube 2 includes a flexible section 21 at the front end and a plastic section 22 at the rear end. A camera 1 is installed at the front end of the flexible section 21, and the rear end of the plastic section 22 is connected to the control module 3. The flexible section 21 includes multiple interconnected snake joints 211. Two traction wires 212A and 212B are spaced apart inside the support tube 2. The front ends of the traction wires 212A and 212B are fixed to the distal snake joints 211, and the proximal ends are connected to the control module 3.

[0036] Furthermore, the control module 3 includes a support housing 31, a knob 32, a turntable 33, and a rotating shaft 34. The knob 32 is located outside the support housing 31, the turntable 33 is located inside the support housing 31, and the rotating shaft 34 is rotatably fixed to the support housing 31 by a bracket 35. The knob 32 and the turntable 33 are mounted on the rotating shaft 34. The proximal ends of two traction wires 212A and 212B are fixed opposite each other relative to the circumference of the turntable 33. By rotating the knob 32, the traction wires 212A and 212B are pulled in two directions, causing the flexible segment 21 to bend upward or downward.

[0037] Furthermore, in order to fix the bending angle of the flexible segment 21, the control module 3 also includes a damping structure, which is used to lock the knob 32 and the turntable 33 when they are rotated to a certain angle, thereby controlling the flexible segment 21 to bend upward or downward and then lock it without returning to its original state.

[0038] As an optional embodiment, the damping structure includes a plurality of friction plates 36 disposed on the rotating shaft 34, the friction plates 36 being pressed together.

[0039] Preferably, the friction pad 36 is made of metal or plastic, and both sides have rough surfaces.

[0040] More preferably, at least two friction pads 36 are stacked together; more preferably, 5-8 friction pads 36 are stacked and pressed together.

[0041] More preferably, the friction plate 36 can rotate relative to the rotating shaft 34.

[0042] Preferably, the turntable 33 is located on the side of the bracket 35 away from the knob 32, and at least two friction plates 36 are disposed between the bracket 35 and the knob 32, with the friction plates 36 pressed tightly against the bracket 35. Preferably, the rotating shaft 34 is provided with a shoulder 341, and the friction plates 36 are pushed against the side of the bracket 35 by the shoulder 341.

[0043] More preferably, there are 3-8 friction plates 36. More preferably, at least one friction plate 36 is disposed between the turntable 33 and the bracket 35 and is pressed together.

[0044] When the knob 32 is turned, the rotating shaft 34 and the turntable 33 are driven to rotate synchronously, pulling the traction wires 212A and 212B, causing the flexible section 21 to bend upward or downward. After the bending angle is adjusted, due to the friction plates 36, there is friction between adjacent friction plates 36 and between the friction plates 36 and the bracket 35. Even if the knob 32 is released, the flexible section 21 will not return to its original state, locking the camera 1 at a certain angle.

[0045] See Figures 6 to 9 This is a schematic diagram of another embodiment of the visually adjustable flexible medical endoscope 10 of this utility model. The parts that are the same as those in the previous embodiment will not be described again.

[0046] As another optional embodiment, the damping structure includes a locking slider 37, and the support housing 31 is provided with a guide groove 311. The locking slider 37 is embedded in the guide groove 311. The locking slider 37 includes a locking ramp 371 in the direction facing the knob 32. When the locking ramp 371 is inserted into the gap between the knob 32 and the support housing 31, the locking ramp 371 makes frictional contact with the inner side of the knob 32 and locks the knob 32.

[0047] Preferably, the locking slider 37 is made of an elastic material, which is selected from at least one of silicone, rubber, and plastic.

[0048] Preferably, the locking slider 37 is provided with a toggle protrusion 372, and the toggle protrusion 372 is provided with spaced anti-slip stripes 373.

[0050] Preferably, the inner surface 374 of the locking slider is flush with the inner surface 312 of the support housing.

[0051] Preferably, the inner surface 321 of the knob is machined to have a rough surface.

[0052] Preferably, the inner surface 321 of the knob is provided with a plurality of raised strips at intervals. Preferably, the raised strips extend radially along the knob, and / or the locking slope 371 of the locking slider 37 is provided with a plurality of grooves, preferably, the extending direction of the grooves is consistent with the extending direction of the raised strips.

[0053] In this embodiment, the camera 1 can be adjusted to a certain angle and locked by locking the slider 37 and the knob 32.

[0054] Furthermore, the damping structures of the two embodiments above can be combined. Another embodiment can be equipped with both the friction plate 36 structure and the locking slider 37 structure to achieve a better angle locking effect.
