Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to an ultrasonic electronic bronchoscope. Background Technology

[0002] In medical settings, ultrasound endoscopes are typically used to emit ultrasound waves into the body of a patient / examinee. By receiving and visualizing the reflected echoes, the internal characteristics of the patient / examinee can be observed, providing a reference for their health status.

[0003] For ultrasound bronchoscopes, the distal portion needs to enter the narrow bronchial lumen. Current ultrasound bronchoscopes, considering the compliance of the distal portion through the lumen or manufacturing costs, typically sacrifice some functions to keep the size within a predetermined range. For example, ultrasound bronchoscopes lack forceps lifting and bending locking functions, and the outer diameter of the distal tip is generally set between 4.9mm and 6.9mm. However, this increases the difficulty of use, making it challenging to properly align the instrument to the target location, effectively limiting the operability of the ultrasound bronchoscope and reducing the efficiency and convenience of ultrasound examinations.

[0076] Example

[0077] This embodiment provides an ultrasonic electronic bronchoscope, see [link / reference] Figure 1 The ultrasonic electronic bronchoscope includes an insertion section 100, an operating section 200, and a light guide section 300. The operating section 200 and the insertion section 100 are fixedly connected. The insertion section 100 has an instrument channel 112 suitable for instrument entry and exit, and a detection component for ultrasonic testing is installed at the distal end of the insertion section 100. The operating section 200 is the structure for user-applied force operation during use; see [link to documentation]. Figure 17 and Figure 21 The insertion portion 100 is configured with a head section 110, a curved section 120 and a flexible section 130.

[0078] For the insertion part 100, the head end section 110, the bending section 120 and the flexible section 130 are fixedly connected in sequence. The flexible section 130 and the operation part 200 are fixedly connected. The bending end of the bending assembly 410 is connected to the far end of the bending section 120.

[0079] In one specific embodiment, the bending segment 120 is configured as a serpentine unit structure, which can be bent at a predetermined angle in at least two directions, up and down. The flexible segment 130 can be configured as a hybrid tube made of stainless steel and resin materials.

[0080] In some embodiments, the detection components include an illumination element 114, an objective lens 115, and an ultrasonic transducer 116. The illumination element 114 and the objective lens 115 are mounted on the distal side of the insertion portion 100 and can be used together to capture external images. The ultrasonic transducer 116 is detachably connected to the insertion portion 100. The ultrasonic transducer 116 is used to emit ultrasonic waves into the human body and then receive the reflected echoes containing information about the human tissue structure, thereby enabling the ultrasonic electronic bronchoscope to perform ultrasound imaging and obtain cross-sectional images of human tissues. Doctors can then diagnose diseases by analyzing the ultrasound images.

[0081] An ultrasonic transducer is one of the following: convex array transducer, linear transducer, sector transducer, and ring transducer.

[0082] In this embodiment, see Figure 2 The operating part 200 is provided with an instrument inlet 201, which is connected to the instrument channel 112; the instrument inlet 201 can be used for the entry and exit of various instruments and the delivery of medicine.

[0083] In some implementations, see Figure 2 The operation unit 200 is provided with a number of remote control buttons 202, which can be configured to control the freezing, unfreezing or other custom functions of the image; the operation unit 200 can have a built-in controller to respond to the control signals of the remote control buttons 202 and perform operations.

[0084] In some implementations, see Figure 2 The operating part 200 is provided with a suction port 203. The operating part 200 is provided with a suction pump and a suction tube. The suction port 203 and the suction tube are connected and the suction pump is installed on the suction tube. The operating part 200 can be equipped with a suction button to connect and turn on and off the suction pump, so that the suction pump can correspondingly draw out sputum and other liquids in the human bronchus, which is beneficial to clear the field of view at the head of the endoscope.

[0085] In some implementations, see Figure 2 The operating part 200 is provided with a water inlet 204, which is used to inject water into the water bladder of the detection component. The support 111 at the distal end of the insertion part 100 can be provided with a communication port to inject water into the water bladder, thereby providing conditions for ultrasonic testing.

[0086] In some implementations, see Figure 22 The light guide section 300 is equipped with a transducer connector 301, an electrical connector 302, and a light guide connector 303. Any connector is electrically connected to the detection component. The electrical connector 302 and the light guide connector 303 are spaced apart on the same end face of the light guide section 300. A light guide tube 304 is provided between the light guide section 300 and the operation section 200. Specifically, the transducer connector 301 is connected to the ultrasound host via a transducer connection line for transmitting electrical signals between the transducer at the end of the endoscope and the ultrasound drive host; the electrical connector 302 is used for signal transmission between the bronchoscope and the imaging host; and the light guide connector 303 is coupled to the light source host to transmit illumination light to the distal end of the bronchoscope for illumination.

[0087] The ultrasonic electronic bronchoscope also includes a bending mechanism 400, which is used to control the bending angle and orientation of the distal end of the insertion part 100.

[0088] In this embodiment, see Figure 5 and Figure 6 The bending mechanism 400 includes a bending component 410 and a locking component 420. The mounting end of the bending component 410 is rotatably connected to the operating part 200, and the bending end of the bending component 410 is drivenly connected to the distal end of the insertion part 100 to adjust and configure the bending and swaying posture of the distal end of the insertion part 100. Its bending operation is convenient and helps users to quickly align the instrument in the insertion part 100 with the target position.

[0089] As an exemplary implementation, see [link to relevant documentation]. Figure 3 and Figure 5 The bending assembly 410 includes a bending handle 411 suitable for contact with the user, an adapter 412, a bending wheel 413, and a control cable 414. The adapter 412 and the bending wheel 413 are detachably connected. One end of the bending handle 411 is fixedly connected to the adapter 412, and the other end of the bending handle 411 extends to the outside of the operating part 200. The adapter 412 and the bending wheel 413 are synchronously rotated within the operating part 200. One end of the control cable 414 is wound around the bending wheel 413, and the other end of the control cable 414 is connected to the distal end of the insertion part 100. In specific implementation, the user pushes the bending handle 411 to rotate relative to the operating part 200. The bending handle 411 drives the adapter 412 and the bending wheel 413 to rotate synchronously. The bending wheel 413 drives the control cable 414 on it to pull the distal end of the insertion part 100 to bend and sway.

[0090] See Figure 21 The curved section 120 of the insertion portion 100 is fixedly connected to the distal end of the control line 414; the control line 414 is provided with two or more, and when the control line 414 is provided with two, it corresponds to the curvature of the curved section 120 in both the vertical and horizontal directions.

[0091] For the detachable connection of the adapter 412 and the bending wheel 413, the adapter 412 and the bending wheel 413 can be connected by snap-fit, fastener locking, or other methods.

[0092] In a specific implementation, the bending mechanism 400 has a first bending state in which "when the locking component 420 unlocks the relative fixation between the bending component 410 and the operating part 200, the bending handle 411 can bend the distal end of the transmission insertion part 100 by external force".

[0093] The bending mechanism 400 also has a second bending state: "When the locking component 420 locks the bending component 410 and the operating part 200 in a relatively fixed position, the bending handle 411 can be rotated by external force to overcome the locking force applied by the locking component 420 to fix the bending component 410 and the operating part 200 in a relatively fixed position, so as to drive the distal end of the insertion part 100 to bend." In the first bending state, the bending of the distal end of the insertion part 100 can be flexibly and freely adjusted by the bending handle 411, which is suitable for large-scale adjustment of the bending angle to find the target orientation; in the second bending state, the bending of the distal end of the insertion part 100 is adjusted by acting on the bending handle 411 to overcome the resistance applied by the locking component 420, which is suitable for small-scale adjustment of the bending angle to align with the target orientation.

[0094] In this embodiment, the mounting end of the locking component 420 and the operating part 200 are rotatably connected. The locking end of the locking component 420 is adapted to be close to the bending component 410 in a first preset position to relatively fix the bending component 410 and correspondingly position the bending and swaying posture of the distal end of the insertion part 100; or it is adapted to be far away from the bending component 410 in a second preset position to unlock the fixing of the bending component 410. The user can actively adjust the locking component 420 to make its locking end move accordingly to lock or unlock the bending component 410; its locking operation is convenient and helps to ensure that the user aligns the instrument in the insertion part 100 with the target position.

[0095] As an exemplary implementation, see [link to relevant documentation]. Figure 3 , Figure 6 and Figure 7 The locking assembly 420 includes a locking handle 421, a positioning member 422, a shaft disc 423, a displacement cylinder 424, a first damping member 425, and a second damping member 426. The locking handle 421 is rotatably mounted on the outside of the operating part 200. The positioning member 422 is fixedly mounted inside the operating part 200 and serves as the main support part of the locking assembly 420. The displacement cylinder 424 is slidably mounted inside the positioning member 422. The shaft disc 423 is connected to the locking handle 421 and is movably mounted inside the displacement cylinder 424. The second damping member 426 is fixedly mounted on the adapter 412 or the bending wheel 413. The first damping member 425 is fixedly connected to the side of the displacement cylinder 424 facing the second damping member 426.

[0096] In some implementations, see Figure 7The displacement cylinder 424 is configured with a first connection position and a second connection position that are spaced out and staggered. The shaft disk 423 is adapted to switch between the first connection position and the second connection position under the action of the locking handle 421. The first damping member 425 and the second damping member 426 are positioned close to each other or released from each other. When the shaft disk 423 is in the first connection position of the displacement cylinder 424, the first damping member 425 and the second damping member 426 are in abutment and limited, and the locking component 420 locks the bending component 410, so that the distal end of the insertion part 100 maintains a bent and swaying posture. When the shaft disk 423 is in the second connection position of the displacement cylinder 424, the first damping member 425 and the second damping member 426 are released from each other, and there is a capacity gap between the first damping member 425 and the second damping member 426 for relative rotation of the bending component 410 and the locking component 420.

[0097] In one specific implementation, see Figure 9 The displacement cylinder 424 has an assembly position 4243 on the side facing the bending wheel 413. The assembly position 4243 is used to fix the first damping component 425, which can be fixed by means of bonding or other methods.

[0098] In one specific embodiment, the first damping element 425 is made of a wear-resistant material, such as Teflon, and the second damping element 426 is made of an elastic soft rubber material, such as silicone, rubber or other soft rubber materials.

[0099] In the first bending state, the first damping element 425 and the second damping element 426 are spaced apart; in the second bending state, the bending handle 411 is rotated by external force to overcome the damping force between the first damping element 425 and the second damping element 426.

[0100] In some embodiments, the damping end faces of the first damping member 425 and the second damping member 426 are conformally arranged. The damping end faces can be set as planes, and the contact surface should be designed as large as possible within the space of the operating part 200 to ensure sufficient contact. Of course, the damping end faces can be set as curved surfaces. It is preferred to set them as planes to enhance the compactness of the structure and optimize the layout space within the operating part 200.

[0101] In some embodiments, the locking assembly 420 further includes a damping retaining ring 430, which is fixedly disposed on the side of the bending wheel 413 facing the first damping member 425. The inner end face of the damping retaining ring 430 is in limiting contact with the second damping member 426. By limiting the second damping member 426 by the damping retaining ring 430, the second damping member 426 is ensured to be in an effective working position, so that the first damping member 425 and the second damping member 426 are symmetrically positioned. Preferably, the second damping member 426 is configured as a circular plate structure.

[0102] In one specific implementation, see Figure 11 The shaft disk 423 is provided with a sliding column 4231, a limiting groove 4232, and a clearance groove 4233. The shaft disk 423 is provided with one or more sliding columns 4231, preferably three. The sliding column 4231 protrudes from the outer periphery of the shaft disk 423. A first groove 4241 is recessed or extends through the displacement cylinder 424. The sliding column 4231 and the first groove 4241 are correspondingly arranged. The sliding column 4231 is slidably disposed within the first groove 4241. A sliding section is provided on the inner wall of the first groove 4241, and two spaced-apart and staggered connecting positions are provided on the sliding section to form a first connecting position and a second connecting position. When the user needs to lock the bending assembly 410 using the locking assembly 420, the user operates the locking handle 421 to slide the sliding column 4231 on the drive shaft disk 423 within the first groove 4241 of the displacement cylinder 424, thereby adjusting the position of the displacement cylinder 424 and causing the first damping element 425 on the displacement cylinder 424 to move closer to / away from the second damping element 426. When the shaft disk 423 drives the displacement cylinder 424 to move, the displacement cylinder 424 is slidably positioned within the operating part 200. A guide structure can be added to the displacement cylinder 424 to improve its movement accuracy.

[0103] See Figure 11 The outer peripheral sidewall of the shaft disk 423 is provided with a limiting groove 4232, and the limiting grooves 4232 are connected to each other by a transition curved surface. A relief groove 4233 is provided on the shaft disk 423, which is located between the outer edge area and the inner center area of ​​the shaft disk 423. The relief groove 4233 is used to avoid the rotation stroke of the adapter 412 when the bending assembly is bent.

[0104] As a further implementation method, see Figure 6 and Figure 7 The locking assembly 420 also includes an elastic support 427, the elastic end of which abuts against and limits the shaft disk 423, and the mounting end of the elastic support 427 is fixedly connected to the positioning member 422. In this configuration, the positioning member 422 provides the mounting base for the elastic support 427, and the elastic support 427 elastically limits the movement of the shaft disk 423 under the transmission of the locking handle 421, thus enhancing the accuracy and stability of the shaft disk 423 and improving the internal compactness of the structure.

[0105] As a further implementation method, see Figure 11Two limiting grooves 4232 are provided on the outer peripheral side wall of the shaft disk 423. The elastic end of the elastic support member 427 is adapted to abut against the limiting grooves 4232. The two limiting grooves 4232 are respectively set to correspond one-to-one with the first connection position and the second connection position. When the shaft disk 423 switches from the first connection position to the second connection position, as the shaft disk 423 rotates, the elastic end of the elastic support 427 slides relative to the shaft disk 4232, switching from one limiting groove 4232 to the other limiting groove 4232. This configuration transforms the connection position into a connection node, further enhancing the accuracy of the relative movement between the bearing and the displacement cylinder 424. When the first damping member 425 and the second damping member 426 are in contact and limited, a stable and reliable contact damping force between the first damping member 425 and the second damping member 426 is ensured, which is beneficial to improving the service life of the locking assembly 420. When the first damping member 425 and the second damping member 426 are out of contact, the first damping member 425 and the second damping member 426 have a defined gap space, which can enhance the stability of the structure and also help reduce the impact on other structures within the operating part 200.

[0106] In some implementations, see Figure 7 and Figure 11 The elastic support 427 includes a cylinder 4271 and a rolling element 4272. The rolling element 4272 is disposed at the end of the cylinder 4271 facing the shaft disk 423, and abuts against the outer peripheral wall of the shaft disk 423. The end of the cylinder 4271 away from the rolling element 4272 is connected to a positioning element 422. The rolling element 4272 is positioned and installed by the cylinder 4271, so that the rolling element 4272 elastically contacts the outer peripheral wall of the shaft disk 423. In a specific embodiment, the elastic support 427 is configured as a ball-head plunger, which has a built-in spring to provide an elastic force on the rolling element 4272.

[0107] In a preferred embodiment, see Figure 7 The elastic support members 427 are centrally symmetrically distributed on the outer periphery of the shaft disk 423, and the constraint direction of the elastic end of the elastic support member 427 is perpendicular to the axial direction of the shaft disk 423. This arrangement helps to enhance the coaxiality and motion stability of the structure.

[0108] In some implementations, see Figure 7 The locking assembly 420 also includes a fixing member 429, which is fixedly connected to a positioning member 422. The fixing member 429 and the positioning member 422 serve as a supporting and fixing base for the locking assembly 420, and are together fixedly connected within the operating part 200. The fixing member 429 and the displacement cylinder 424 are slidably configured to ensure stable displacement of the displacement cylinder 424 under the drive of the shaft disk 423. The fixing member 429 is disposed between the displacement cylinder 424 and the positioning member 422.

[0109] As a further embodiment, the displacement cylinder 424 is provided with a second groove 4242, see [reference]. Figure 7 and Figure 8 The second groove 4242 and the elastic support 427 are correspondingly provided, with the second groove 4242 configured to avoid the installation space of the elastic support 427; correspondingly, the fixing member 429 is provided with a notch, which is correspondingly provided with the elastic support 427, and is configured to avoid the installation space of the elastic support 427; accordingly, see Figure 10 The positioning member 422 includes a connecting portion 4223, which has a connecting groove suitable for assembling the elastic support member 427. This arrangement helps to enhance the compactness of the structure.

[0110] In some embodiments, the locking assembly 420 further includes a force transmission shaft 428, see [link to relevant documentation]. Figure 11 and Figure 16 One end of the force transmission shaft 428 is fixedly connected to the locking handle 421, and the other end of the force transmission shaft 428 is inserted into the shaft disc 423 for transmission; see also Figure 10 The positioning component 422 includes a positioning part 4221, and the force transmission shaft 428 passes through the positioning part 4221. The positioning part 4221 is adapted to slide and limit the force transmission shaft 428. The shaft disk 423 is provided with a insertion hole for the force transmission shaft 428 to drive and cooperate. The shaft disk 423 and the force transmission shaft 428 are arranged coaxially.

[0111] In some implementations, see Figure 5 The adapter 412 includes an adapter plate 4121 and an adapter post 4122. The adapter plate 4121 is connected to the bending handle 411. One end of the adapter post 4122 is fixedly connected to the adapter plate 4121, and the other end of the adapter post 4122 is inserted into the bending wheel 413. The shaft plate 423 is provided with a clearance groove 4233, and the adapter post 4122 passes through the clearance groove 4233. The adapter post 4122 and the clearance groove 4233 are correspondingly arranged. See also Figure 10 The positioning component 422 includes a limiting part 4222, and the limiting part 4222 and the adapter plate 4121 are rotatably configured.

[0112] One or more adapter pins 4122 are provided. For two or more adapter pins 4122, they can be centrally symmetrically distributed and connected to the adapter plate 4121. Multiple adapter pins 4122 are beneficial to enhance the stability and synchronicity of the transmission force. In a specific embodiment, two adapter pins 4122 are provided, and the two adapter pins 4122 are spaced apart. The two adapter pins 4122 are respectively passed through the two clearance grooves 4233 on the shaft plate 423.

[0113] The ultrasonic electronic bronchoscope also includes a lifting mechanism 500, which is used for the movement and displacement of the instrument within the instrument channel 112 to match the user's usage needs.

[0114] In this embodiment, see Figures 12 to 14 The clamping mechanism 500 includes a displacement component 510 and a drive component 520. The displacement component 510 is connected to the drive end of the drive component 520. At least a portion of the displacement component 510 is disposed within the insertion portion 100. The drive component 520 is rotatably disposed within the operation portion 200. The displacement component 510 includes a clamping seat 511 adapted to abut against an instrument. The clamping seat 511 is used to adjust the bending angle of the instrument extending out of the instrument channel 112.

[0115] The lifting clamp seat 511 is configured to slide within the insertion portion 100, and the drive assembly 520 is capable of driving the lifting clamp seat 511 to move toward or away from the distal port of the instrument channel 112 along its sliding direction.

[0116] As an exemplary embodiment, the insertion portion 100 is provided with a support 111, and the support 111 is provided with a sliding position 113. The lifting clamp seat 511 is configured to slide in the sliding position 113. The displacement assembly 510 also includes a traction member 512. One end of the traction member 512 is fixedly connected to the lifting clamp seat 511, and the other end of the traction member 512 is fixedly connected to the driving end of the drive assembly 520. The drive assembly 520 drives the traction member 512 to move, thereby causing the lifting clamp seat 511 to slide relative to the support 111.

[0117] In some implementations, see Figure 18 and Figure 20 The displacement assembly 510 also includes a constraint member 513, which is installed within the support 111. The constraint member 513 is adapted to constrain and limit the lifting clamp seat 511 to configure a first limit position and a second limit position for sliding relative to the support 111. The first limit position is located at the proximal end relative to the second limit position. By constraining the travel of the lifting clamp seat 511 relative to the support 111 through the constraint member 513, the extreme positions of the sliding movement of the lifting clamp seat 511 are limited, preventing the risk of the lifting clamp seat 511 slipping out and falling.

[0118] In one specific implementation, see Figure 18The lifting clamp seat 511 includes a sliding part 5111 and a supporting part 5112. The sliding part 5111 and the restraining member 513 are slidably connected, and the supporting part 5112 and the instrument are slidably abutted. In the first extreme position, the supporting part 5112 can overlap with the extension direction of the lifting section 1122; in the second extreme position, the supporting part 5112 can retract from overlapping with the extension direction of the lifting section 1122. When initially loading the instrument onto the endoscope, placing the lifting clamp seat 511 in the second extreme position avoids affecting the extension of the instrument, allowing the instrument to be inserted into and out of the straight section 1121, extending directly to the distal end of the endoscope. When it is necessary to adjust the bending angle of the instrument, the traction member 512 is driven to move the lifting clamp seat 511 backward, away from the second extreme position.

[0119] In one specific embodiment, to improve the sealing of the endoscope lifting clamp seat 511 and prevent body fluids in the human cavity from adhering to the traction member 512 and spreading with the traction member 512, the displacement assembly 510 also includes a sealing member 514, see [link to documentation]. Figure 18 and Figure 20 The insertion portion 100 has a tube through which the traction member 512 passes, and a sealing member 514 is located at the distal end of the tube. The sealing member 514 can seal the traction member 512 to prevent body fluid from directly entering the tube in which the traction member 512 is located.

[0120] In some embodiments, an elastic element (not shown in the figure) is sleeved on the outer side of the traction member 512. The elastic element and the traction member 512 extend in the same direction. When the traction member 512 is subjected to a bending force applied by the internal structure of the insertion portion 100, the elastic element elastically compresses and limits the traction member 512, keeping the traction member 512 in good straightness. The elastic element provides elastic support for the traction member 512, providing reliable working conditions when the drive assembly 520 drives the traction member 512 to move and push / pull the clamp seat 511. In a specific embodiment, the traction member 512 is a steel wire rope, and the elastic element can be an elastic sleeve spring to enhance the straightness maintenance of the steel wire rope.

[0121] See Figure 19 The instrument channel 112, partially disposed within the support 111, includes a straight section 1121 and a lifting section 1122, the extension direction of the lifting section 1122 being inclined to the extension direction of the straight section 1121. In a specific embodiment, the clamp seat 511 may be disposed in the extension direction of the straight section 1121; naturally, the sliding direction of the clamp seat 511 and the extension direction of the straight section 1121 are inclined to intersect each other, with an intersection angle between 10-50°, preferably between 15-45°.

[0122] After the bending assembly 410 bends the distal end of the insertion part 100, the bending and swaying posture of the distal end of the insertion part 100 is locked by the locking assembly 420; the instrument in the instrument channel 112 moves accordingly with the bending and swaying posture, and the position of the distal end of the instrument is further adjusted by the lifting clamp mechanism 500, making it easier for the user to operate on the desired area, and providing a basis for the user to perform fine control operation.

[0123] In a specific implementation, the bending angle of the instrument raised by the sliding contact of the lifting clamp seat 511 is set to 1-12 degrees, preferably 5 degrees, 8 degrees, 10 degrees, etc.

[0124] As an exemplary implementation, see [link to relevant documentation]. Figure 13 and Figure 14 The drive assembly 520 includes a clamp handle 521, a rotating frame 522, a telescopic member 523, and a limiting member 524. One end of the clamp handle 521 is detachably connected to the rotating frame 522, and the other end of the clamp handle 521 extends to the outside of the operating part 200. The rotating frame 522 is rotatably configured within the operating part 200. One end of the telescopic member 523 is rotatably configured with the rotating frame 522, and the other end of the telescopic member 523 is rotatably configured with the operating part 200. The proximal end of the traction member 512 is fixedly connected to the telescopic member 523. The limiting member 524 is installed within the operating part 200. The rotating frame 522 and the limiting member 524 are slidably connected to adjust the telescopic displacement of the telescopic member 523, so that the traction member 512 can pull or push the clamp seat 511 to slide closer to or away from the distal port of the instrument channel 112.

[0125] The limiting component 524 is used to limit the rotation angle of the rotating frame 522. On the one hand, it ensures the adjustment of the telescopic displacement of the telescopic component 523 itself. On the other hand, it strengthens the control of the lifting clamp displacement. Two extreme positions are set by limiting to accurately meet the working position of lifting the instrument and the working position of avoiding the extension of the instrument.

[0126] When it is necessary to lift the distal end of the instrument at the distal end of the instrument channel 112, the user rotates the lifting clamp handle 521, causing the lifting clamp handle 521 to drive the rotating frame 522 to rotate synchronously. During the sliding process of the rotating frame 522 relative to the limiting member 524, the telescopic displacement of the telescopic cylinder 4271 is linked, causing the traction member 512 to push and pull the lifting clamp seat 511 to slide.

[0127] In some implementations, see Figure 15The telescopic member 523 includes a first cylinder 5231 and a second cylinder 5232 that can slide relative to each other. The end of the first cylinder 5231 away from the second cylinder 5232 is rotatably configured with the operating part 200, and the end of the second cylinder 5232 away from the first cylinder 5231 is rotatably configured with the rotating frame 522. The proximal end of the traction member 512 is fixed inside the first cylinder 5231, the traction member 512 extends out of the second cylinder 5232, and the distal end of the traction member 512 is fixed with the lifting clamp seat 511. When the first cylinder 5231 and the second cylinder 5232 slide relative to each other, the traction member 512 slides inside the second cylinder 5232 to push and pull the lifting clamp seat 511 to displacement.

[0128] Among them, the limiting member 524 is equipped with a guide groove. When the rotating frame 522 slides on the guide groove, it can drive the telescopic member 523 to telescopically move. Through the sliding contact of the first cylinder 5231 with the traction member 512, the traction member 512 can push, pull and lift the clamp seat 511.

[0129] The ultrasonic electronic bronchoscope provided in this embodiment is equipped with a lifting clamp mechanism 500, which has a lifting clamp function and can adjust the bending angle of the instrument extending out of the instrument channel 112, which is beneficial for the user to quickly align the instrument with the target position.

[0130] The ultrasonic electronic bronchoscope provided in this embodiment is easy to use and can quickly and reasonably align the instrument with the target location to obtain a beneficial field of view of the detection components, so as to perform operations on the desired area. It can provide a basis for users to perform precise control operations. This invention is beneficial to improving the efficiency and flexibility of ultrasonic detection.

[0131] In one specific implementation, the ultrasonic electronic bronchoscope is not equipped with a lifting clamp mechanism 500, which allows for a more optimized size and structure, with a smaller tip. This facilitates extending the depth of the insertion part 100 tip into the bronchus. It is also equipped with a bending locking function, which allows the user to lock it after determining the bending angle, reducing the difficulty of use and improving the ease of operation.

[0132] See Figure 3 and Figure 4The operating section 200 includes mounting bases for the bending assembly 410 and the locking assembly 420. The operating section 200 also includes a fixedly connected assembly plate 205 and a positioning plate 206. The bending assembly 410 is rotatably mounted on the positioning plate 206, and the bending wheel 413 and the positioning plate 206 are rotatably configured relative to each other. The locking assembly 420 and the bending assembly 410 are mounted on the same side of the positioning plate 206. The positioning member 422, the fixing member 429, and the positioning plate 206 are detachably connected. The assembly plate 205 and the positioning plate 206 together form a space for the components within the light guide tube 304 of the light guide section 300 to enter the operating section 200, extending through the operating section 200 to the distal end of the insertion section 100, thus improving structural integration. The operating section 200 includes a sleeve 207 for guiding the components within the light guide tube 304 into this space.

[0133] As a specific implementation process, the configured detection component can provide feedback on the image information of the user's desired operating area, allowing the user to know the bending condition of the instrument. When the instrument extends a long distance, the desired lifting height can be achieved by a shorter sliding motion of the lifting clamp seat 511. When the instrument extends a short distance, the desired lifting height can be achieved by a longer sliding motion of the lifting clamp seat 511. Adjusting the lifting height of the distal end of the instrument is flexible and convenient.

[0134] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
