Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a visualization device and integrated system that can be integrated with a bronchoscope. Background Technology

[0002] Early detection and diagnosis of lung cancer are crucial for improving patient survival rates. The vast majority of early-stage lung cancers present as peripheral pulmonary nodules, lesions located in segmental lungs and distal bronchi. Currently, bronchoscopy is difficult to access distal sites and often lacks a working channel, making interventional procedures impossible. Traditional electronic bronchoscopes, due to their large outer diameter, struggle to navigate the tortuous bronchial tree to reach the peripheral region where nodules are located, creating diagnostic blind spots. To address accessibility issues, clinicians often utilize small ultrasound probes. However, ultrasound provides indirect imaging information; it can indicate the presence of space-occupying lesions outside the airway but cannot effectively differentiate between benign and malignant lesions (e.g., it is difficult to distinguish tumors from benign lesions such as inflammation and fibrosis). Pathological diagnosis remains the gold standard, but obtaining pathological specimens requires precise sampling under direct vision. Using separate ultra-fine instruments (such as biopsy forceps or brushes) under X-ray guidance carries the risk of "blind puncture" and is inefficient. Therefore, there is an urgent clinical need for an integrated solution that can directly access the deepest bronchi, provide a visual view, and enable precise interventional procedures under visualization to meet clinical needs. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The purpose of this invention is to provide a visualization instrument and integrated system that can be integrated with a bronchoscope to solve the problems existing in the prior art and facilitate operation and treatment under direct vision at deeper locations.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1 This embodiment provides a visualization instrument that can be integrated with a bronchoscope. Please refer to [link to documentation]. Figures 1-5 The system includes a flexible catheter 1, an image acquisition unit 3, an actuator 4, and a manipulation mechanism 5. The flexible catheter 1 is used to insert into the working channel 24 of the bronchoscope 2, and the distal end 11 of the flexible catheter 1 can extend through the instrument outlet 21 at the distal end of the bronchoscope 2. The image acquisition unit 3 is disposed at the distal end 11 and is used to communicate with the image processing module. The image acquisition unit 3 is used to acquire tissue image information and can send it to the image processing module. The actuator 4 is disposed at the distal end 11 and is used to perform one or more of sampling or treatment. The manipulation mechanism 5 is connected to the proximal end of the flexible catheter 1 and is connected to the actuator 4 so as to manipulate the action of the actuator 4.

[0022] In this invention, a visualization instrument is integrated with a bronchoscope 2. Based on the visualization provided by the bronchoscope 2, images are further acquired using a smaller visualization instrument. The actuator 4 is controlled by the manipulation mechanism 5 to sample or treat tissues. This allows the visualization instrument to directly access the deepest bronchus and provides multiple visualization views, enabling precise interventional procedures under visualization and improving operational efficiency.

[0023] Among them, the flexible catheter 1 is made of multi-layer composite material braided tube and covered with a polymer sheath, which gives it good pushability, flexural strength and biocompatibility; its outer diameter is less than 2.8 mm to meet the requirements of small channels.

[0024] In an optional embodiment, more preferably, the image acquisition unit 3 includes an image detection element 31, which is placed at the center of the distal end 11 and used to acquire tissue image information directly in front of it. The image detection element 31 is communicatively connected to the image processing module through a transmission element 32 disposed inside the flexible catheter 1.

[0025] The image detection element 31 is positioned at the center to provide a forward field of view. Specifically, the image detection element 31 is a miniature CMOS image sensor, which is connected to a wire via a transmission element 32, such as a miniature PCB board, and further communicates with a micro connector at the near end via the wire to transmit image information. The PCB board is fixedly disposed within the far end head 11.

[0026] In an optional embodiment, more preferably, the image acquisition unit 3 further includes an illumination component 33, which is disposed around the image detection component 31 and is used for illumination.

[0027] In order to acquire images more clearly, micro LEDs or optical fibers 306 are arranged around the image detection component 31 as illumination components 33; the illumination component 33 is connected to the micro connector at the proximal end through a wire disposed inside the flexible conduit 1 so as to transmit power.

[0028] In the optional scheme of this embodiment, more preferably, a detection hole is provided at the center of the far end head 11, the detection end of the image detection component 31 is placed at the detection hole, and a transparent cover plate 34 is sealed at the detection hole.

[0029] The transparent cover 34 is a glass cover that can be embedded in the detection hole to protect the lens from corrosion by tissue fluid without affecting the field of view of the image detection component 31.

[0030] In the optional embodiment, more preferably, the distal end 11 is provided with a lens rinsing hole 12, which is used to face the transparent cover plate 34. The operating mechanism 5 is provided with a rinsing port 51, and the flexible conduit 1 is provided with a rinsing channel. The rinsing port 51 can be connected to an external rinsing device. One end of the rinsing channel is connected to the rinsing port 51 and is used to introduce rinsing fluid through the rinsing port 51. The other end of the rinsing channel is connected to the lens rinsing hole 12 and is used to rinse the transparent cover plate 34 through the lens rinsing hole 12.

[0031] In order to avoid blurring of the view on the transparent cover plate 34, the transparent cover plate 34 is rinsed by setting a lens rinsing hole 12. The rinsing port 51 is set on the finger ring 54 of the operating mechanism 5 and is connected to the lens rinsing hole 12 through the internal rinsing channel. An external rinsing device is connected to rinse at least the outer surface of the transparent cover plate 34. The rinsing port 51 adopts a standard Luer connector or other micro fluid quick-connect interface.

[0032] In the optional embodiment, more preferably, the distal end 11 is also provided with an environmental rinsing and suction hole 13. The environmental rinsing and suction hole 13 is used to face the tissue. The other end of the rinsing channel away from the rinsing port 51 is also connected to the environmental rinsing and suction hole 13 and can rinse the tissue environment through the environmental rinsing and suction hole 13. The rinsing port 51 can also be connected to a negative pressure device to draw liquid from the tissue environment through the environmental rinsing and suction hole 13.

[0033] When it is necessary to rinse the mucus and body fluids on the tissue to facilitate clear observation of the tissue, since the internal rinsing channel is connected to the environmental rinsing and suction port 13, the external rinsing device can rinse the front tissue through the environmental rinsing and suction port 13. The rinsing direction of the environmental rinsing and suction port 13 is parallel to the field of view. In addition, when it is necessary to drain the tissue fluid in front of the field of view, the external negative pressure is set through the rinsing port 51, and the tissue fluid is aspirated through the environmental rinsing and suction port 13. Furthermore, in order to facilitate the control of the flow path of the environmental rinsing and suction port 13 and the lens rinsing port 12, two rinsing channels can be set inside the flexible catheter 1, and correspondingly, two rinsing ports 51 are set. The integration of rinsing and suction can quickly clean the lens when it is contaminated and aspirate excess liquid, maintain a clear field of view, avoid the operation of repeatedly removing instruments for cleaning, and ensure the continuity and efficiency of the operation.

[0034] Specifically, when the distal end is obscured by contaminants during the operation, the flushing can be initiated in two ways: an assistant connects a syringe filled with saline solution to the flushing port 51 and manually injects the flushing solution; or, one end of the flushing tubing is connected to the flushing port 51 and the other end is connected to an automatic flushing pump, which is then controlled by the doctor via a foot switch or button; the flushing solution is ejected through the flushing channel from the lens flushing port 12 and the environmental rinsing and suction port 13, directly flushing the transparent cover plate 34 and the tissue.

[0035] In the optional scheme of this embodiment, more preferably, the actuator 4 includes a sampling clamp 41, which is movably disposed at the distal end 11. The sampling clamp 41 is connected to the operating mechanism 5 through a sampling guide wire disposed inside the flexible conduit 1. The operating mechanism 5 can control the retraction and extension of the sampling guide wire to drive the sampling clamp 41 to move.

[0036] In this embodiment, the sampling action is performed by the actuator 4. The actuator 4 includes a sampling clamp 41, specifically a conventional two-lobed clamp. The clamp lobes are made of alloy material and are hinged to the distal end 11 housing via a pin 42. A sampling guide wire, such as a sampling steel wire, passes through a cavity inside the flexible catheter 1, and its distal end is connected to a drive rod of the two clamp lobes. When the steel wire is pulled back and forth, it drives the clamp lobes to rotate around the pin, thereby opening and closing. In addition, a sealing ring is provided at the joint between the distal end 11 and the drive rod to prevent tissue fluid from entering and causing corrosion. Furthermore, in practical applications, the actuator 4 can be replaced as needed, such as by pre-installing a retractable cell brush for brushing or pre-installing a quartz fiber optic interface for transmitting laser energy for laser treatment.

[0037] In the optional embodiment, more preferably, the portion of the flexible catheter 1 extending out of the instrument outlet 21 is provided with a curved section 14, and the distal end 11 is provided at the distal end of the curved section 14. The curved section 14 is connected to the operating mechanism 5 through a curved guide wire 15 provided inside the flexible catheter 1. The operating mechanism 5 can control the extension and retraction of the curved guide wire 15 to drive the movement of the curved section 14.

[0038] The flexibility of the distal end 11 can be improved by setting the bending section 14. Specifically, the bending section 14 can adopt a conventional catheter bending structure, such as a section of laser-cut metal tube, which has good flexibility in a single direction. The bending guide wire 15 pulls the steel wire through the flexible catheter 1, with the distal end fixed to the distal end of the bending section 14 and the proximal end connected to the operating mechanism 5. Pulling the steel wire can bend the bending section 14 to that side.

[0039] In the optional embodiment, more preferably, the operating mechanism 5 includes an operating handle 52, which includes a thumb ring 53 and a finger ring 54 that are relatively movable. One end of the finger ring 54 is detachably connected to the proximal end of the flexible catheter 1, such as by insertion. The thumb ring 53 is connected to the sampling guidewire. A curved lever 55 is slidably disposed on the finger ring 54 and is connected to the curved guidewire 15. A micro connector is also disposed inside the finger ring 54. The image acquisition unit 3 is used to communicate with the electrical interface 22 of the electrical head 23 at the proximal end of the bronchoscope 2 through the micro connector, and can then communicate with the image processing module through the electrical head 23.

[0040] The operating handle 52 is ergonomically designed and can take the form of a mainstream handheld device, a handle similar to a biopsy instrument, or an endoscope. In this embodiment, the operating handle 52 is configured with a thumb ring 53 and a finger ring 54 that can move relative to each other, such as sliding. The proximal end of the sampling guidewire is fixed to the thumb ring 53. The opening and closing of the distal clamp flap is directly controlled by pinching and releasing the fingers, providing an operating experience with no learning cost. Moreover, the bending lever 55 moves back and forth along the groove on the finger ring 54. The proximal end of the bending guidewire 15 is connected to the bending lever 55. Pushing the bending lever 55 forward relaxes the bending guidewire 15, and the distal bending segment 14 straightens in the direction of vision under the elastic action of the metal tube of the bending segment 14 and the external protective rubber. Pulling the bending lever 55 backward tightens the wire and bends the bending segment 14.

[0041] In addition, the micro-connector inside the finger ring 54 can be a conventional connector such as an ODU connector, and connect to the electrical head of the bronchoscope 2 for transmitting image signals and power. It can also optionally include a storage chip for encoding tool ID so that the host of the bronchoscope 2 can automatically identify and call up parameters.

[0042] Example 2 This embodiment provides an integrated system including a bronchoscope 2, an image processing module, and a visualization instrument that can be integrated with the bronchoscope 2 as in Embodiment 1. The bronchoscope 2 includes an image acquisition component 25 disposed at the distal end, and an electrical head 23 disposed at the proximal end of the bronchoscope 2. The image acquisition component 25 is communicatively connected to the electrical head 23. A flexible catheter 1 passes through the working channel 24 of the bronchoscope 2 and extends out through the instrument outlet 21 at the distal end of the bronchoscope 2. The image processing module is communicatively connected to both the image acquisition component 25 and the image acquisition unit 3, and is capable of acquiring and displaying the image information acquired by the image acquisition component 25 and the image acquisition unit 3.

[0043] During operation, depending on the patient's lesion location, the flexible catheter 1 of the visualization instrument is first inserted through the working channel 24 of the bronchoscope 2 until it extends out of the bronchoscope 2 through the instrument outlet 21 and reaches the segmental bronchus (level 5 and below). Then, the dedicated tool interface at the end of the tool cable is plugged into the pre-set electrical interface 22 on the operating section of the bronchoscope 2. By integrating the signal transmission of the visualization instrument with the bronchoscope 2 through a plug-in interface design, the cumbersome use of an additional host and monitor is avoided, simplifying the operating room layout and reducing overall costs. This connection, on the one hand, provides... The image detection component 31 and illumination component 33 of the instrument are powered, and the image signal is transmitted to the image processing module, i.e., the host, which is integrated in the bronchoscope 2. The host simultaneously receives the image signal of the bronchoscope 2 and the image signal of the visualization instrument. After being synthesized by its image processing module, the picture-in-picture (PIP) signal is output to the display. The position of the small window of the picture-in-picture is adjustable, and the user can switch it with one click to swap the content of the main screen and the small screen. By observing the screen, the doctor can simultaneously grasp the overall positioning field of the bronchoscope 2 and the local detail field of the sub-scope, so as to perform navigation and biopsy.

[0044] In addition, a modular design can be adopted, which allows for the detachable connection of costly core components and disposable components that come into contact with patients. The disposable component is the distal end 11, on which the image acquisition unit 3 can be detachably mounted via plug-in or other means. The distal end 11 can be plugged into and fixed to the distal end of the curved section 14. The remaining parts are designed to be sterilized by high temperature and high pressure sterilization or low temperature plasma sterilization for reuse.

[0045] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
