Description

A bronchoscope and sputum suction tube component Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a bronchoscope and a sputum suction tube component. Background Art

[0002] At present, whether in the ICU ward or other treatment departments of the hospital, there are patients who cannot cough on their own due to severe respiratory diseases or other serious diseases. When patients who cannot cough up sputum on their own have too much sputum in their respiratory tract, the sputum can easily block the airway, causing the patient to have difficulty breathing, hypoxia, and even suffocation and death. In addition, some patients inhale their own vomit into the airway and cannot cough it out normally, or when newborn babies inhale amniotic fluid, the airway is prone to blockage. In order to clear the obstruction in the airway, it is usually necessary to suction the patient. At present, most patients still use simple disposable suction tubes for suctioning. Since the simple disposable suction tube can only be used for blind suction and the position of the suction tube in the respiratory tract cannot be accurately controlled, the suction effect is poor and it is difficult to ensure that all the airway obstructions are sucked out.

[0003] In order to completely remove the obstruction in the airway, a bronchoscope is usually used for visual suction to suck out all the obstructions inside the respiratory tract. In addition, according to the needs of disease examination and identification, a sputum sample from a certain part of the trachea will be extracted through a bronchoscope for testing. At present, bronchoscopes are expensive medical devices with high prices and high cost of use. After each use, they must be thoroughly disinfected and sterilized to prevent cross-infection between different patients. At present, when disinfecting and sterilizing a bronchoscope, it is difficult to completely and thoroughly disinfect and sterilize the inside of the suction tube inside the bronchoscope, and the cost of disinfection and sterilization is relatively high. Summary of the Invention

DETAILED DESCRIPTION

[0045] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0046] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0047] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0048] Due to the long inner hole of the suction tube, disinfection and sterilization are difficult and costly. Moreover, once the suction tube is blocked or damaged, the entire bronchoscope will be scrapped because the suction tube cannot be replaced. To address this problem, the present application provides a bronchoscope that is easy to replace the suction tube. The suction tube is configured on the outside of the bronchoscope tube. After suctioning with the suction tube, the suction tube can be removed and replaced. There is no need to sterilize the inner hole of the suction tube. Different patients will not share the same suction tube, and cross infection due to the suction tube will not occur.

[0049] In one embodiment, referring to FIG. 1 and FIG. 2 , the bronchoscope includes an operating handle 1 , a mirror tube 2 , a camera unit 3 , and a wiring harness 4 . The mirror tube 2 has a mirror tube proximal end 21 and a mirror tube distal end 22 for inserting into a human body.

[0050] In this application, the proximal end and the distal end are described based on the distance from the operating handle 1 during use. For example, in this application, the distal end 22 of the mirror tube is the end of the mirror tube 2 that is farthest from the operating handle 1, and the proximal end 21 of the mirror tube is the end of the mirror tube 2 that is connected to the operating handle 1.

[0051] The operating handle 1 is connected to the proximal end 21 of the bronchoscope tube 2 and is used to operate the bronchoscope tube 2. The operating handle 1 can operate the bronchoscope tube 2 in various ways. For example, referring to Figures 1 and 8, the bronchoscope tube 2 includes a bend adjustment portion 221, which is located at the distal end 22 of the bronchoscope tube and is used to adjust the posture of the distal end 22. The bronchoscope includes a transmission cable 6 for adjusting the bending state of the bend adjustment portion 221. The transmission cable 6 extends from the operating handle 1 into the bronchoscope tube 2 and is connected to the bend adjustment portion 221. The bend adjustment portion 221 includes multiple snakes 2211. By operating the transmission cable 6 through the operating handle 1, the relative position of adjacent snakes 2211 can be changed, thereby adjusting the bending state of the bend adjustment portion 221. For another example, the distal end 22 of the bronchoscope tube does not need to be adjusted in posture. The proximal end 21 of the bronchoscope tube can be directly fixed to the operating handle 1, and the bronchoscope tube 2 can be directly inserted into the bronchus using the operating handle 1. The mirror tube 2 can be made of any feasible material, such as a metal hose made of metal strands commonly used in the prior art, with the metal hose coated with polyurethane material; for another example, an injection molded tube with performance that meets the requirements can be used.

[0052] The camera unit 3 is used to acquire image information of the target area and is disposed at the distal end 22 of the lens tube. The camera unit 3 can employ various structures capable of digital image acquisition. For example, conventionally, it can include a lens, a photosensitive chip, a lighting module, and an integrated circuit board that provides corresponding control functions. As a preferred solution, the lighting module can employ an LED cold light source with adjustable brightness. The camera unit 3 can employ an existing general-purpose small camera assembly. It should be noted that the camera unit 3 and the lens tube 2 are divided into two components based on their respective functions, and their mechanical structures can be integrated with each other. For example, the packaging structure of the camera unit 3 can be designed as an integral part of the distal end 22 of the lens tube, or the packaging structure of the camera unit 3 itself can become part of the distal end 22 of the lens tube.

[0053] A wiring harness 4 extends from the operating handle 1 into the mirror tube 2 and connects to the camera unit 3 to transmit image information. Specifically, one end of the wiring harness 4 is connected to the camera unit 3, and the other end is used to connect to an external power supply and data processing equipment (such as a host computer) to power the camera unit 3 and transmit captured image data.

[0054] The outside of the endoscope tube 2 is provided with a suction tube mounting structure, which is used to allow the suction tube 7 to be detachably mounted on the outside of the endoscope tube 2. The suction tube mounting structure can be in various feasible forms. For example, referring to Figures 1 and 5, the suction tube mounting structure includes a mounting groove 23 on the outside of the endoscope tube 2, the shape of which is adapted to the suction tube 7 so that the suction tube 7 can be accommodated therein; for another example, the suction tube mounting structure is a buckle on the outside of the endoscope tube 2, which is used to hold the suction tube 7.

[0055] The distal end 22 of the mirror tube is used to configure the distal end 71 of the suction tube 7. The distal end 22 of the mirror tube is configured with a hole, a groove or a joint for adapting to the distal end 71 of the suction tube. The hole, the groove or the joint is adapted to the shape of the distal end 71 of the suction tube so that the distal end 71 of the suction tube is accommodated in the hole or the groove, or is combined with the joint.

[0056] Referring to Figures 1 and 3 , the suction tube 7 has a proximal end 72 and a distal end 71 . The proximal end 72 is the end closest to the operating handle 1 , while the distal end 71 is the end farther from the operating handle 1 . The proximal end 72 has a proximal opening, which serves as a negative pressure suction interface for connection to a negative pressure air source. The distal end 71 has a distal opening for suctioning sputum. There are many feasible situations for the suction tube 7 to suck sputum. For example, the distal opening of the distal end 71 of the suction tube can directly suck sputum. At this time, the distal opening of the suction tube 7 is directly exposed to the end of the distal end 22 of the mirror tube, and the sputum in the airway is directly sucked into the suction tube 7 by the distal opening of the suction tube 7; for another example, the distal opening of the distal end 71 of the suction tube is connected to the distal tube of the distal end 22 of the mirror tube (not shown in Figures 1 and 3), the distal tube is a short tube, and the distal tube mouth of the distal tube sucks sputum. The distal opening of the distal end 71 of the suction tube is connected to the proximal tube mouth of the distal tube. When the suction tube 7 is sucked by a negative pressure air source, negative pressure is generated in the suction tube 7, and then negative pressure is also generated in the distal tube connected to the suction tube 7. The sputum in the patient's trachea or bronchus is sucked into the distal tube and then sucked into the suction tube 7.

[0057] It should be noted that the end in this article refers to the area at the end, which can be understood as an area with a certain length at the end, and is not limited to the end face.

[0058] The bronchoscope of the present application can realize the detachable configuration of the suction tube 7 on the outside of the scope tube 2 through the suction tube installation structure. After using the suction tube 7 to suction sputum, the suction tube 7 can be directly replaced without the need to disinfect and sterilize the inner hole of the suction tube 7, thereby reducing the disinfection difficulty and disinfection cost of the bronchoscope, thereby reducing the use cost of the visual suction equipment.

[0059] Furthermore, in one embodiment, referring to Figures 1, 5, and 7, the mounting groove 23 is adapted to fit the suction tube 7. The mounting groove 23 extends along the length of the tube 2 and has a disassembly opening 231 extending along the length of the tube 2. The disassembly opening 231 is used to disassemble and install the suction tube 7. By extending the mounting groove 23 along the length of the tube 2, the suction tube 7 can be effectively protected when installed therein, preventing it from being flattened or tangled. Compared to the plug-and-play disassembly of the suction tube 7, the disassembly opening 231 extending along the length of the tube 2 allows for quick removal of the suction tube 7.

[0060] Furthermore, in one embodiment, referring to FIG5 , a portion of the tube wall of the mirror tube 2 is recessed inwardly, forming a crescent-shaped cross-section of the mirror tube 2. The recessed portion of the tube wall forms a mounting groove 23. The crescent-shaped cross-section of the mirror tube 2 allows the suction tube 7 to be inserted into the mounting groove 23, creating a relatively smooth transition between the outer wall of the mirror tube 2 and the outer circumference of the suction tube 7, thereby minimizing the risk of scratching the airway.

[0061] Specifically, referring to Figure 5 , the portion of the tube 2 that is recessed inward is the recessed portion 24, while the remaining portion is the exposed portion 25. A smooth transition is formed between the recessed portion 24 and the exposed portion 25, resulting in a smooth outer surface of the tube 2. Specifically, in one embodiment, the suction tube 7 is a circular tube made of a soft, non-toxic medical plastic, and the wall surface of the mounting groove 23 is a circular arc surface.

[0062] In some other embodiments, the mounting groove 23 may be formed not only by a recessed portion within the scope tube 2 but also by any other feasible method. For example, the inner hole of the scope tube 2 may remain circular, and the mounting groove 23 may be injection molded on the outside of the scope tube 2. The shape of the mounting groove 23 may be selected as needed. For another example, the scope tube 2 may be a dual-channel tube, with one channel forming the inner hole of the scope tube 2 and the other channel forming the mounting groove 23. In contrast, a scope tube 2 with a crescent-shaped cross-section is smaller in size and better suited to the working environment of a bronchoscope.

[0063] To further facilitate the removal of the suction tube 7, in one embodiment (see Figure 5), the disassembly opening 231 is a tapered opening, allowing the suction tube 7 to be clipped into the mounting slot 23. The disassembly opening 231 is a tapered opening, meaning its width is smaller than the diameter of the suction tube 7. When inserting or removing the suction tube 7, at least one of the suction tube 7 and the scope tube 2 must elastically deform before the suction tube 7 can pass through the disassembly opening 231. This prevents the suction tube 7 from automatically falling out of the mounting slot 23, improving reliability. To remove the suction tube 7, simply pull one end of the suction tube 7 out of the disassembly opening 231. The remaining portion of the suction tube 7 can then be removed from the mounting slot 23 by pulling through the disassembly opening 231, making the removal operation more convenient. Of course, although the scope tube 2 has a disassembly opening 231, other methods of disassembly and removal of the suction tube 7 can also be used, depending on actual needs, such as inserting or removing the suction tube 7 through a notch at the end of the mounting slot 23 by inserting or removing it.

[0064] To further facilitate removal of the suction tube 7, in one embodiment, the endoscope tube 2 includes a plug connector (not shown) at the distal end 22 of the endoscope tube. The plug connector is configured to connect to the distal end of the suction tube 7 and has a connector hole (not shown) for communicating with the tube hole of the suction tube 7. The plug connector facilitates installation of the suction tube 7. The plug connector can be implemented in any feasible manner, and the specific form will be described below.

[0065] In some other embodiments, in addition to using a plug connector, the tube 2 may also reserve space at the distal end 22 of the tube to expose the distal opening of the suction tube 7. In this case, the distal opening of the suction tube 7 can directly suction sputum. For example, the mounting slot 23 can be used to prevent the distal end 22 of the tube from being removed from the mounting slot 231. To prevent the suction tube 7 from moving in the direction of extension of the tube 2, the proximal end 72 of the suction tube can be fixed to the operating handle 1 or the proximal end 21 of the tube.

[0066] In one embodiment, please refer to Figures 1 and 8, the mirror tube 2 includes a bending adjustment portion 221. It is difficult to process the groove on the outer wall of the bending adjustment portion 221, so the mounting groove 23 does not extend to the bending adjustment portion 221. In one embodiment, the snake tube 2211 has a suction tube insertion space for inserting the suction tube 7. Specifically, in one embodiment, please refer to Figures 1 and 8, the mirror tube 2 includes a distal head 26, and the camera unit 3 is configured on the distal head 26. The distal head 26 has a suction port 261, and the distal tube 27 is connected to the suction port 261. After the suction tube 7 passes through the bending adjustment portion 221, it is directly connected to the suction port 261 at the distal end of the mirror tube to form a suction channel. At this time, the distal head 26 forms a plug connector for plugging into the suction tube 7. In some other embodiments, the suction tube 7 can also be directly inserted into the distal head 26 and the distal opening of the suction tube 7 forms a suction port, so that the sputum directly enters the suction tube 7 without entering the distal head 26 and then entering the suction tube 7.

[0067] Since it is difficult to insert the suction tube 7 into the curved adjustment part 221, in one embodiment, please refer to Figures 1 and 8, the bronchoscope includes a distal tube 27 for suctioning sputum (not shown in Figures 1 and 8), the curved adjustment part 221 includes a proximal joint 2212 of the adjustment part and a plurality of snake tubes 2211, the proximal joint 2212 of the adjustment part is connected to at least one snake tube 2211, the proximal joint 2212 of the adjustment part is at the proximal end of the curved adjustment part 221, and the proximal joint 2212 of the adjustment part is connected to the distal tube 27.

[0068] There are several ways to connect the distal tube 27 and the sputum suction tube 7 to the proximal connector 2212 of the regulating part:

[0069] For example, in one embodiment, one end of the proximal joint 2212 of the adjusting portion is connected to the suction tube 7, and the other end is connected to the distal tube 27, thereby achieving communication between the distal tube 27 and the suction tube 7. Specifically, in one embodiment, the proximal joint 2212 of the adjusting portion is plugged into the suction tube 7. At this time, the proximal joint 2212 of the adjusting portion forms a plug joint that is plugged into the suction tube 7. The proximal joint 2212 of the adjusting portion and the distal tube 27 are plugged together and have an interference fit. The proximal joint 2212 of the adjusting portion and the distal tube 27 can be connected in any other feasible manner, such as welding, bonding, or clamping.

[0070] For another example, referring to FIG11 , in one embodiment, the bending adjustment portion includes a connecting tube 2214 connected to the proximal joint 2212 of the adjustment portion. The connecting tube 2214 communicates with the distal tube 27. The distal end of the connecting tube 2214 is connected to the proximal joint 2212 of the adjustment portion. The proximal end of the connecting tube 2214 is used to be plugged into the sputum suction tube 7, so that the sputum suction tube 7 can suction sputum through the connecting tube 2214 and the distal tube 27. During sputum suction, the sputum suction tube 7 is in a negative pressure state. Since the connecting tube 2214 and the distal tube 27 are both in communication with the sputum suction tube 7, the interiors of the connecting tube 2214 and the distal tube 27 are also in a negative pressure state. Sputum enters the sputum suction tube 7 through the distal tube 27 and the connecting tube 2214 and is sucked out of the airway.

[0071] Specifically, referring to FIG11 , the hole of the connecting tube 2214 communicates with the hole of the distal tube 27. There are various ways in which the hole of the connecting tube 2214 and the hole of the distal tube 27 can communicate with each other. For example, the connecting tube 2214 and the distal tube 27 can be directly connected, so that the hole of the connecting tube 2214 and the hole of the distal tube 27 are directly connected. In another example, the inner hole of the proximal joint 2212 of the adjusting portion can connect the hole of the connecting tube 2214 and the hole of the distal tube 27.

[0072] In one embodiment, referring to FIG11 , the inner hole of the proximal end connector 2212 of the adjusting portion connects the tube hole of the connecting tube 2214 with the tube hole of the distal tube 27. The distal end of the connecting tube 2214 is inserted into the inner hole of the proximal end connector 2212 of the adjusting portion, and the proximal end of the distal tube 27 is inserted into the inner hole of the proximal end connector 2212 of the adjusting portion. The inner hole of the proximal end connector 2212 of the adjusting portion has an annular positioning protrusion 22120 that separates the connecting tube 2214 from the distal tube 27.

[0073] The connection between the connecting tube 2214 and the suction tube 7 can be carried out in any feasible manner. For example, in one embodiment, the proximal end opening of the connecting tube 2214 is large, and the suction tube 7 can be inserted into the connecting tube 2214. At this time, the connecting tube 2214 forms a plug connector for connection with the suction tube 7; for another example, in one embodiment, please refer to Figure 11, a connector 2215 is installed at the proximal end of the connecting tube 2214, and the distal end 71 of the suction tube is inserted into the connector 2215. At this time, the connector 2215 forms a plug connector for connection with the suction tube 7.

[0074] The connecting tube 2214 and the proximal joint 2212 of the adjusting part can be connected in any feasible manner, such as the connecting tube 2214 is inserted into the proximal joint 2212 of the adjusting part and glued together, or the connecting tube 2214 is inserted into the proximal joint 2212 of the adjusting part with interference fit to achieve fixation, or the connecting tube 2214 and the proximal joint 2212 of the adjusting part are welded and fixed, or the connecting tube 2214 and the proximal joint 2212 of the adjusting part are threaded or clamped together.

[0075] Specifically, in one embodiment, referring to FIG11 , the connecting tube 2214 and the connector 2215 do not need to be removed along with the suction tube 7. The connector 2215 is tubular, and the proximal end of the connecting tube 2214 is inserted into the connecting tube 2215, and the proximal end 72 of the suction tube is also inserted into the connector 2215. Since the connecting tube 2214 is not a disposable part, the performance requirements of the connecting tube 2214 are higher than those of the suction tube 7, and the connecting tube 2214 should be made of corrosion-resistant material.

[0076] In one embodiment, referring to FIG11 , the scope tube 2 includes a scope body 29, with a bend adjustment portion 221 located at the distal end of the scope body 29. A mounting slot 23 is located on the scope body 29, connecting the scope body 29 to a proximal end connector 2212 of the adjustment portion via a pipe joint 210. One end of a connecting pipe 2214 is inserted into the proximal end connector 2212 of the adjustment portion, and the other end is inserted into the mounting slot 23 on the scope body 29.

[0077] In one embodiment, referring to Figures 1, 9, and 10, an operating handle 1 is used to control the operation of the lens tube 2. The operating handle 1 includes an upper handle cover 101, a lower handle cover 102, an operating knob 106, an image freeze button 104, a capture button 103, and a store button 105. The upper handle cover 101 and the lower handle cover 102 form the handle housing. The upper handle cover 101 and the lower handle cover 102 are snap-fitted and fastened with screws. The operating knob 106 is mounted on the lower handle cover 102.

[0078] In one embodiment, referring to Figure 5 , the scope tube 2 is made of a soft, non-toxic medical material. The scope tube 2 has three scope tube holes 28 . The transmission wire 6 is a steel wire. Two transmission wires 6 are provided. The circular scope tube holes on either side are used to pass through an elastic tube 8 and the transmission wires 6 . The transmission wires 6 are threaded within the elastic tube 8 . Together, the elastic tube 8 and the transmission wires 6 control the bending of the bend adjustment portion 221 . In one embodiment, the elastic tube 8 is made of stainless steel.

[0079] Please refer to Figures 1 and 8. The bending adjustment part 221 includes a snake tube 2211, a distal joint 2213 of the adjustment part, a proximal joint 2212 of the adjustment part, and an outer sleeve. The snake tube 2211 is a snake tube. The distal joint 2213 of the adjustment part is connected to the distal head 26. The distal end of the transmission line 6 is connected to the distal joint 2213 of the adjustment part. By pulling, contracting, and releasing and stretching the transmission line 6, the bending adjustment part 221 can be bent 180° in both directions, which is convenient for the operator. The mirror tube hole 28 in the middle of the mirror tube 2 is used to pass the wire harness 4. In one embodiment, the suction tube 7 can also be used to directly insert into the distal head 26. In this case, the distal opening of the suction tube 7 serves as the suction port.

[0080] Since the end faces of each section of the serpentine tube 2211 are two symmetrical inclined planes symmetrically distributed on both sides of its central plane, pulling the transmission line 6 on one side can tilt the serpentine tube 2211 in one direction, thereby causing the entire bending adjustment portion 221 to bend in one direction, and pulling the transmission line 6 on the other side can cause the bending adjustment portion 221 to bend in the other direction, thereby enabling the distal head 26, the camera unit 3 and the suction port 261 to change direction by 180° in both directions.

[0081] Referring to Figures 9 and 10, the operating knob 106 and the rotating wheel 107 are fastened together using a fastening screw 108. Rotating the operating knob 106 drives the rotating wheel 107 to rotate together. One end of each of the two transmission cables 6 is fixed to the rotating wheel 107 via two screws 109, and the two transmission cables 6 are drawn out from both sides of the rotating wheel 107 via guide slots 1071. When the rotating wheel 107 rotates, one of the transmission cables 6 is pulled. Since the two transmission cables 6 are respectively wound around the two sides of the rotating wheel 107, when the rotating wheel 107 rotates in one direction, one transmission cable 6 is tightened while the other transmission cable 6 is loosened. This allows the bending adjustment portion 221 to be bent in one direction by rotating the operating knob 106. Changing the rotation direction of the operating knob 106 changes the bending direction of the bending adjustment portion 221. The purpose of bending the bending adjustment portion 221 by operating the knob 106 is to change the direction of the sputum suction port and align it with the location of the sputum so that all the sputum in the trachea can be completely sucked out.

[0082] The function of the pressing plate 112 is to fix the two elastic tubes 8 passing through the transmission line 6 so that they are fixed on the lower cover 102 of the operating handle.

[0083] The operating knob 106 is mounted on the handle lower cover 102. Two elastic tubes 8 and a transmission line 6 pull the bend adjustment portion 221, causing it to bend 180 degrees up and down, thereby changing the direction of the camera unit 3 and the sputum suction port 261. The image freeze button 104, the capture button 103, and the storage button 105 are all fixedly mounted on the operating handle housing.

[0084] In order to facilitate the installation of the suction tube 7 and facilitate the suction operation, the bronchoscope needs to be equipped with other components that are compatible with the suction tube 7 when in use. To facilitate understanding of the structure and working principle of the bronchoscope, the structure of the suction tube components is described in detail below. It should be noted that the suction tube components of the present application can be removed from the bronchoscope as a whole and replaced as a whole. In some embodiments, the suction tube 7 can adopt the structure described above and will not be described in detail below.

[0085] In one embodiment, please refer to Figures 3, 4, 6 and 7, the suction tube component includes a suction tube 7 and a mounting seat 9, the suction tube 7 has a suction tube distal end 71 and a suction tube proximal end 72, the suction tube proximal end 72 is fixed to the mounting seat 9 and is used to connect to a negative pressure source. In one embodiment, the negative pressure source adopts a negative pressure pump, and the negative pressure generated by the negative pressure pump sucks the sputum in the patient's trachea and bronchi out of the body through the suction tube 7. In some other embodiments, the negative pressure source can also be a negative pressure storage device connected to the negative pressure pump, and the suction tube proximal end 72 is connected to the negative pressure pipeline of the negative pressure storage device. The suction tube 7 and the mounting seat 9 can be fixed in various feasible ways, such as the suction tube 7 and the mounting seat 9 are integrally formed, and the suction tube 7 and the mounting seat 9 are installed separately, and the mounting seat 9 can be fixed together with the suction tube 7 by clamping, bonding or clamping.

[0086] The mounting base 9 has a mounting structure for being detachably mounted on the outside of the operating handle 1 or the outside of the bronchoscope's tube 2, so that the sputum suction tube 7 can be disposed outside the tube 2. The proximal end 72 of the sputum suction tube is detachably mounted on the outside of the operating handle 1 or the outside of the tube 2 of the bronchoscope via the mounting base 9. This improves the reliability of the proximal end 72 of the sputum suction tube when the sputum suction tube 7 is assembled with the bronchoscope. When the sputum suction tube 7 needs to be removed and replaced, the mounting base 9 can be removed along with the sputum suction tube 7 for replacement, without the need for disinfection or sterilization of the mounting base 9.

[0087] The distal end 71 of the suction tube is configured to be attached to the distal end 22 of the bronchoscope. The distal end 71 of the suction tube has a distal opening for suctioning sputum. The configuration of the distal end 71 of the suction tube and the bronchoscope can be any of the embodiments described above, and the details will not be repeated here.

[0088] Furthermore, in order to facilitate the disassembly and installation of the mounting seat 9, in one embodiment, please refer to Figures 3, 4 and 7, the seat mounting structure includes a clamping structure for clamping on the outside of the operating handle 1. The clamping structure can realize the rapid disassembly and installation of the mounting seat 9. In some other embodiments, in addition to adopting the clamping structure, the seat mounting structure can also adopt any other feasible method to replace the clamping structure. For example, the seat mounting structure can be a magnetic structure, which is fixed to the operating handle 1 by magnetism; for another example, the seat mounting structure can also be a clamping hoop, which is clamped and fixed to the operating handle 1 or the mirror tube 2 by the clamping hoop; for another example, the seat mounting structure can also include a fastener, which fixes the base to the operating handle 1 by the fastener, and the fastener can be a fastening screw.

[0089] Specifically, in one embodiment, referring to Figures 3, 4, and 7, the retaining structure includes a first latch 91 facing the operating handle 1, and the operating handle 1 is provided with a first latching groove corresponding to the first latch 91, thereby achieving a detachable connection between the mounting base and the operating handle 1. When replacing the mounting base 9 and the suction tube 7, the first latch 91 between the mounting base 9 and the operating handle 1 is manually disengaged to separate the suction tube component from the bronchoscope. Conversely, when installing, only the first latch 91 needs to be manually fastened, thereby facilitating the installation and replacement of the mounting base.

[0090] Regarding the mounting method of the mounting base 9 and the suction tube 7, in one embodiment, please refer to Figures 3, 4, and 7. The mounting base 9 includes a base 92 and a base cover 93 fixed to the base 92. A portion of the suction tube 7 is sandwiched between the base 92 and the base cover 93, and the mounting structure is located on at least one of the base 92 and the base cover 93. The base 92 and the base cover 93 are clamped together to secure the suction tube 7 more reliably. In one embodiment, the first buckle 91 is located on the base 92.

[0091] In one embodiment, a second buckle 94 is installed on the seat cover 93, and a second slot corresponding to the second buckle 94 is opened on the base 92. Here, the seat cover 93 is connected to the base 92 through the second buckle 94, and the seat cover 93 can be easily removed without tools.

[0092] Furthermore, in one embodiment, referring to Figures 3, 4, 6 and 7, the suction tube 7 includes a suction valve 73, which is used to control the on-off of the channel between the distal end 71 and the proximal end 72 of the suction tube, thereby controlling the on and off of the suction function. The suction valve 73 facilitates the control of the suction operation. In some other embodiments, in addition to providing the suction valve 73 on the suction tube 7, the suction operation can also be controlled by controlling the passage between the negative pressure air source and the suction tube 7, such as providing a suction valve on the negative pressure air source.

[0093] Specifically, in one embodiment, referring to Figures 6 and 7 , the suction valve 73 is installed in the mounting seat 9, and the operating button of the suction valve 73 is exposed from the mounting seat 9. Both the base 92 and the seat cover 93 have positioning grooves therein for positioning the suction valve 73. When the seat cover 93 is closed, the positioning grooves on the base 92 and the seat cover 93 clamp the suction valve 73, thereby securing the suction valve 73.

[0094] In one embodiment, referring to Figures 1, 3, and 4, the mounting base 9 and the operating handle 1 are arranged along the extension direction of the mirror tube 2. To avoid the mirror tube, the mounting base 9 has an escape groove 95 for the mirror tube 2 to pass through. The base cover 93 and the base 92 are also arranged along the extension direction of the mirror tube 2. The first buckle 91 is located on the side of the base facing the operating handle 1. The base 92 engages with the operating handle 1 along the length of the mirror tube 2, thus facilitating assembly of the mounting base 9 and the operating handle 1.

[0095] In one embodiment, referring to Figures 1 and 10 , to enhance the reliability of the suction tube 7 and the endoscope tube 2, the suction tube assembly includes an elastic buckle 10 that detachably secures the suction tube 7 to the endoscope tube proximal end 21, thereby preventing the suction tube 7 from separating from the endoscope tube 2 during use. The elastic buckle 10 has a zigzag slot that allows the suction tube 7 to be directly fastened to the endoscope tube 2.

[0096] Furthermore, the bronchoscope may need to be inserted with an instrument during use. In order to adapt to more application scenarios, in one embodiment, please refer to Figures 3, 4 and 7. The suction tube 7 has an operating channel port, and the operating channel port is used to allow the operating instrument to enter the suction tube 7. The suction tube 7 includes a sealing cover 74, and the sealing cover 74 is removably covered at the operating channel port. When it is necessary to operate the instrument, the sealing cover 74 is opened, and the instrument is inserted into the suction tube 7 through the operating channel port for operation. When the instrument is not operated, the sealing cover 74 can block the operating channel port, which can prevent foreign matter such as dust from intruding and can also achieve sealing of the inner hole of the suction tube during suction. In some other embodiments, according to the needs of use, the suction tube 7 may not be equipped with an operating channel port. In this case, the suction tube 7 is specifically used for suction operation.

[0097] Specifically, in one embodiment, please refer to Figures 3, 4 and 7, the suction tube 7 includes a tube body 75 and a connector 76, and the operating channel port is on the connector 76. The suction valve 73 is connected to the connector 76. In one embodiment, the connector 76 is a Y-shaped three-way tube, and the Y-shaped three-way tube has three connecting ports and the three connecting ports are interconnected, one of which is connected to the tube body 75, the second connecting port is connected to the suction valve 73, and the third connecting port serves as the operating channel port. In one embodiment, the sealing cover 74 is made of a material with a certain elasticity, such as a silicone material. In one embodiment, the tube body 75 and the connector 76 are interference fit together and cannot be disassembled. In some other embodiments, the connector and the tube body can also be connected in a detachable manner, such as a threaded connection or a connection through a detachable connector. In this case, the tube body can be replaced separately in some occasions.

[0098] The bronchoscope of the present application can not only be used to examine and diagnose lung tracheal and bronchial lesions, but can also be used for visual suction of patients whose airways are blocked by sputum. After visual suction of the patient, the suction tube parts that are contaminated during suction can be replaced and reused once, solving the problem of difficulty in thoroughly disinfecting and sterilizing the inner hole of the suction tube and the high cost of disinfection and sterilization, greatly reducing the cost of using a bronchoscope for visual suction, and also reducing the risk of cross-infection between different patients due to sharing the same bronchoscope.

[0099] In one embodiment, in addition to using the mounting base 9 to fix the bronchoscope to the proximal end 72 of the suction tube, the bronchoscope can also maintain the position of the suction tube 7 only through the mounting groove 23, and the mounting base 9 is not required.

[0100] In one embodiment, please refer to Figures 1 to 10. The operation process of suctioning using a bronchoscope and a suction tube 7 is: when the patient needs suctioning, the suction tube component is installed on the bronchoscope, and the male connector connected to the image data cable 11 is inserted into the female connector on the operating handle 1. After power is turned on, the image from the camera unit 3 can be seen from the display (not shown in the figure). Connect the proximal end 72 of the suction tube to the negative pressure source, adjust the negative pressure value according to the suction requirements, and then insert the bronchoscope tube 2 into the patient's trachea or bronchus through the patient's oral or nasal cavity according to the medical operation requirements and procedures for inserting a bronchoscope into the human body. While inserting, observe the sputum accumulation in the respiratory tract on the display screen. If there is sputum, press the suction valve 73 to open the negative pressure to suction the sputum. If there is viscous sputum on the tracheal wall and it is a certain distance away from the sputum suction port and the sputum cannot be sucked out, the knob 106 can be operated to bend the bending adjustment part 221 in the direction of the sputum, so that the sputum suction port 261 is aligned with the sputum, so that all the sputum can be easily sucked out.

[0101] When the suction is completed, pull out the mirror tube 2, open the first buckle 91, and then remove the mounting seat 9 and other disposable replaceable parts of the suction tube components. After the bronchoscope is disinfected, sterilized and dried, install the new suction tube components for next use.

[0102] In one embodiment, referring to Figures 12 to 21 , the distal end of the suction tube 7 is sealedly connected to the proximal end of the distal tube 27 via a sealing module 5. The proximal end of the distal tube 27 now extends beyond the bend adjustment portion 221. The distal end of the distal tube 27 is directly connected to the suction port 261 of the distal head 26. In other embodiments, the sealing module 5 can replace the connector 2215 to connect the suction tube to the connecting tube 2214.

[0103] The suction tube 7 is connected to the distal tube 27 through the sealing module 5 to prevent air leakage between the suction tube 7 and the distal tube 27 during negative pressure suction, thereby reducing the effect of negative pressure suction and allowing all sputum in the trachea to be completely sucked out.

[0104] The sealing module 5 includes a middle sealing tube 51, two fixed sleeves 52 and an outer shielding tube 53. Specifically, one of the fixed sleeves 52 is installed on the distal end of the suction tube 7, and the other fixed sleeve 52 is installed on the proximal end of the distal tube 27, wherein the middle sealing tube 51 is installed between the two fixed sleeves 52.

[0105] Therefore, when using and installing the aforementioned suction tube 7 and distal tube 27, first insert the distal end 71 of the suction tube into one of the fixed sleeves 52, and then insert the proximal end of the distal tube 27 into the other fixed sleeve 52. The two fixed sleeves 52 are then connected to the intermediate sealing tube 51. The distal tube 27 is also provided with an inner extension tube 271, so that the inner extension tube 271 can be inserted into the distal end 71 of the suction tube to enhance the sealing performance. The outer shielding tube 53 is then installed outside the two fixed sleeves 52. This allows the aforementioned sealing module 5 to seal the suction tube 7 and distal tube 27, preventing air leakage between the suction tube 7 and distal tube 27 during negative pressure suction, thereby reducing the effectiveness of negative pressure suction and allowing all sputum in the trachea to be completely suctioned out.

[0106] Furthermore, the above-mentioned intermediate sealing tube 51 includes an intermediate flange 511 and two internal spiral tubes 512, wherein the two internal spiral tubes 512 are respectively installed on both sides of the intermediate flange 511. Here, a sealing ring 513 is installed on the inner side of the intermediate flange 511, and the connection between the above-mentioned two fixed sleeves 52 is sealed and blocked by the sealing ring 513 to prevent air leakage.

[0107] Furthermore, in order to install the fixed sleeve 52 on the intermediate sealing tube 51, anti-movement tubes 514 are respectively installed on both sides of the sealing retaining ring 513, and anti-movement ridges 515 are installed on the anti-movement tubes 514. An anti-movement groove 516 is provided between the anti-movement tube 514 and the internal screw tube 512, and an anti-movement notch 524 is provided at one end of the outer guide tube 521, and an anti-movement ridge 515 is installed on the anti-movement tube 514. Therefore, when the outer guide tube 521 is inserted into the anti-movement groove 516, the anti-movement ridge 515 needs to pass through the anti-movement notch 524 and enter between the outer guide tube 521 and the fixed sleeve 52, that is, the anti-movement tube 514 extends between the outer guide tube 521 and the fixed sleeve 52. Therefore, after the fixed sleeve 52 is inserted into the anti-movement tube 514, the inner sealing ridge 523 presses against the sealing retaining ring 513, so that the fixed sleeve 52 is installed on the intermediate sealing tube 51.

[0108] Furthermore, in order to improve the sealing performance, there are threads on the outer wall of the internal screw tube 512, and an outer guide tube 521 is installed on the fixed sleeve 52, and a first external screw tube 522 is installed on the outer guide tube 521, so that the first external screw tube 522 can be connected to the internal screw tube 512 by rotating the first external screw tube 522. Here, the outer guide tube 521 is provided with an outer retaining ring 5210 and an inner retaining ring 5211. The first external screw tube 522 presses against the inner retaining ring 5211, so that the fixed sleeve 52 is firmly connected to the middle sealing tube 51, and further increases the degree to which the inner sealing convex ring 523 presses against the sealing retaining ring 513, which helps to improve the sealing performance.

[0109] Furthermore, in order to enable the fixed sleeve 52 to fix the sputum suction tube 7 (distal tube 27 ), a second external screw 525 is installed on the fixed sleeve 52 , and the fixed sleeve 52 is fixed to the sputum suction tube 7 through the second external screw 525 .

[0110] An inner movable groove 526 is provided in the second external screw tube 525 of this structure, and an inner screw tube body 527 is installed in the inner movable groove 526, so that the inner screw tube body 527 can be screwed onto the outer fixed screw thread 529 of the fixed sleeve 52 by rotating the second external screw tube 525. Furthermore, an elastic conical sealing plug 530 is installed at the other end of the fixed sleeve 52, and the elastic conical sealing plug 530 can further seal the gap between the fixed sleeve 52 and the second external screw tube 525.

[0111] Furthermore, in order to shield the above-mentioned fixed sleeve 52, an outer peripheral groove 528 is opened on the outer wall of the second external screw tube 525, and the above-mentioned outer shielding tube 53 includes a first C-shaped shielding body 531 and a second C-shaped shielding body 532. Among them, the first C-shaped shielding body 531 is equipped with a first outer fin 533, and a first inner C-shaped bar 534 corresponding to the outer peripheral groove 528 is installed on its inner wall. The second C-shaped shielding body 532 is equipped with a second outer fin 535, and a second inner C-shaped bar 536 corresponding to the outer peripheral groove 528 is installed on its inner wall. Therefore, when the first C-shaped shielding body 53 1. After the second C-shaped shielding body 532 is buckled into the fixed sleeve 52, the first outer wing 533 and the second outer wing 535 are sleeved in the outer peripheral groove 528; further, a fixing block 537 is installed at the end of the first outer wing 533, and a fixing groove 538 is opened at the end of the second outer wing 535. Therefore, when the fixing block 537 is inserted into the fixing groove 538, the special-shaped block 539 on the first C-shaped shielding body 531 is inserted into the special-shaped groove 540 of the second C-shaped shielding body 532, thereby realizing the shielding installation of the above-mentioned outer shielding tube 53 on the two fixed sleeves 52, which is convenient for the use of negative pressure suction.

[0112] In an embodiment of a sputum suction tube component, the sputum suction tube component can be the sputum suction tube component described in any of the above embodiments, and the details will not be repeated.

[0113] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
