Description

Technical Field

[0001] This application relates to the field of medical technology, and in particular to an imaging puncture combination device. Background Technology

[0002] Mini-ultrasound probes are a common method for diagnosing early-stage cancers and tumors in human cavities. By combining endoscopy and ultrasound, a miniature high-frequency ultrasound probe is placed within the instrument channel of the endoscope. The probe rotates 360 degrees at high speed within the probe cavity to acquire histological features of the layered structure of the human cavity and ultrasound tomographic images of surrounding organs, thereby confirming early-stage cancers and tumors within the tissue and enabling early tumor detection. This is currently a commonly used method for diagnosing lesions in human cavities. Biopsy is an essential procedure in tumor diagnosis and treatment. Pathological diagnosis through puncture biopsy can effectively improve the accuracy of imaging and ultrasound diagnoses. Tumor ablation technology, guided by modern imaging techniques (such as ultrasound, CT, MRI, etc.), applies chemical or physical methods to focal solid tumors (single or multiple), directly eradicating or destroying tumor tissue. This is a precise and minimally invasive interventional diagnostic and treatment technique.

[0003] Currently, when a suspicious lesion is detected requiring sampling or ablation, a small ultrasound probe is first used to confirm its location. The probe is then withdrawn from the endoscope, and a biopsy or ablation instrument is inserted for sampling or ablation. However, because the ultrasound probe is withdrawn during sampling or ablation, the procedure relies solely on the previously identified location, making it impossible to determine if the instrument is accurately inserted into the tissue to be sampled or ablated, leading to inaccurate positioning. For narrow areas or regions inaccessible to the endoscope, multiple samplings are often performed to ensure optimal results. Even then, sufficient samples may not be obtained, or the actual lesion may not be captured at all, potentially damaging other tissues during ablation. Furthermore, multiple samplings prolong treatment time, damage surrounding tissues, and may lead to misdiagnosis. They can also damage the instrument channel of the endoscope, affecting its lifespan.

[0004] Therefore, existing sampling or ablation methods suffer from low accuracy and high cost, and need to be improved. Summary of the Invention

[0005] This application provides an imaging puncture combination device to alleviate the technical problems of low accuracy and high cost of existing sampling or ablation methods.

[0009] An angle adjustment assembly includes an abutment member and a push-pull assembly. The abutment member is disposed between the puncture device and the imaging device. Under the control of the push-pull assembly, the abutment member moves along the axial direction of the imaging device and abuts against the puncture tip. The included angle between the puncture tip and the imaging tip is positively correlated with the distance between the abutment member and the imaging tip along the axial direction.

[0010] In one embodiment, the puncture device includes a puncture tube and a puncture instrument, and the imaging device includes an imaging tube and an imaging instrument. The puncture tube and the imaging tube are fixedly connected, the puncture instrument can move in and out of the puncture tube, and the imaging instrument can move in and out of the imaging tube.

[0011] In one embodiment, the abutting member includes a bottom surface and a top surface, the bottom surface abutting against the imaging conduit and the top surface abutting against the puncture conduit, and the height of the top surface from the bottom surface gradually increases in a first direction near the imaging front end.

[0012] In one embodiment, the push-pull assembly includes a guide rail, a sliding member, and a control mechanism. The guide rail is disposed between the puncture tube and the imaging tube and is fixedly connected to the puncture tube and the imaging tube. The guide rail includes a groove along the axial direction. The abutment member is located outside the guide rail and is fixedly connected to the sliding member. Under the control of the control mechanism, the sliding member slides along the groove in the guide rail.

[0013] In one embodiment, the push-pull assembly further includes a traction member, a first end of which is connected to the control mechanism, and a second end of which is connected to the sliding member. When the control mechanism pulls the traction member, the abutment member slides in a second direction away from the imaging front end.

[0014] In one embodiment, the push-pull assembly further includes a reset member that resets the abutment member along a first direction close to the imaging front end when the control mechanism stops pulling the traction member.

[0015] In one embodiment, the reset member is a spring, which is sleeved outside the traction member and located inside the groove.

[0016] In one embodiment, the push-pull assembly further includes a protective sleeve that is fitted over the outside of the traction member and located between the guide rail and the control mechanism, and the protective sleeve is fixedly connected to the puncture tube and the imaging tube.

[0017] In one embodiment, the imaging puncture assembly further includes a housing, and the control mechanism, the puncture conduit, and the imaging conduit are detachably connected to the inner wall of the housing. The housing includes a first opening, a second opening, a third opening, and a fourth opening. The front ends of the puncture conduit and the imaging conduit face the first opening, the rear end of the puncture conduit faces the second opening, the rear end of the imaging conduit faces the third opening, and the operating area of ​​the control mechanism faces the fourth opening.

[0018] In one embodiment, the angle adjustment component includes a pre-bending member disposed on the inner wall of the housing. A first end of the pre-bending member is connected to the control mechanism, and a second end of the pre-bending member is connected to the front end of the housing. The front end of the housing is provided with the first opening. When the control mechanism pulls the pre-bending member, the puncture tip and the imaging tip bend synchronously.

The puncture device includes a puncture tip; the imaging device is arranged side-by-side outside the puncture device, and includes an imaging tip close to the puncture tip; the angle adjustment component includes an abutment member and a push-pull component. The abutment member is disposed between the puncture device and the imaging device, and moves along the axial direction of the imaging device under the control of the push-pull component, abutting against the puncture tip.

By integrating the puncture device and the imaging device into one unit, this application allows both devices to be inserted into the endoscope simultaneously. The imaging tip of the imaging device can reflect in real time whether the puncture tip is accurately inserted into the target tissue to be sampled or ablated.

[0032] like Figure 1 The diagram shown is a three-dimensional structural schematic of the imaging puncture combination device provided in this application embodiment. The imaging puncture combination device includes a puncture device 10, an imaging device 20, and an angle adjustment component 30. The puncture device 10 includes a puncture tip 11. The imaging device 20 is arranged side by side outside the puncture device 10 and includes an imaging tip 21, which is close to the puncture tip 11. The angle adjustment component 30 includes an abutment member 31 and a push-pull component 32. The abutment member 31 is disposed between the puncture device 10 and the imaging device 20. Under the control of the push-pull component 32, the abutment member 31 moves along the axial direction of the imaging device 20 and abuts against the puncture tip 11. The included angle between the puncture tip 11 and the imaging tip 21 is positively correlated with the axial distance between the abutment member 31 and the imaging tip 21.

[0033] The puncture device 10 and the imaging device 20 are arranged side by side, that is, their axes are parallel or nearly parallel. Figure 1 In this context, the axis refers to the vertical direction. The puncture device 10 and imaging device 20 each include relatively flexible and relatively inflexible parts; the aforementioned axis refers to the axis of the relatively inflexible parts. The imaging tip 21 is close to the puncture tip 11, meaning they face the same direction. Figure 1 Both are facing upwards. When the combined device is in use, the images acquired in real time by the imaging front end 21 can be used to locate the lesion tissue, and the puncture front end 11 performs sampling or ablation on the lesion tissue according to the location. Since both are facing the same direction, the imaging front end 21 will also observe in real time whether the puncture front end 11 is accurately inserted into the lesion tissue to be sampled or ablated. If any deviation is observed during insertion, the insertion angle needs to be adjusted.

[0034] The puncture tip 11 of the puncture device 10 is flexible relative to the imaging device 20. Therefore, adjusting the insertion angle specifically involves adjusting the angle between the puncture tip 11 and the imaging tip 21. The angle is controlled by an angle adjustment assembly 30, which includes an abutment member 31 and a push-pull assembly 32. The abutment member 31 is located between the puncture device 10 and the imaging device 20 and abuts against the puncture tip 11. The push-pull assembly 32 is connected to the abutment member 31 and can push or pull the abutment member 31, causing it to move forward or backward along the axis of the imaging device 20. During this movement, the abutment member 31 remains in contact with the puncture tip 11. Figure 1 In the middle, "forward" means vertically upward, and "backward" means vertically downward. When the push-pull assembly 32 pushes the abutting member 31, the abutting member 31 moves forward along the axial direction. When the push-pull assembly 32 pulls the abutting member 31, the abutting member 31 moves backward along the axial direction.

[0035] The angle between the puncture tip 11 and the imaging tip 21 is positively correlated with the axial distance between the abutment member 31 and the imaging tip 21. As the abutment member 31 moves axially, the distance between it and the imaging tip 21 gradually decreases when moving forward and gradually increases when moving backward. Because the abutment member 31 abuts against the puncture tip 11, it constantly exerts a force on the puncture tip 11 during its movement. This force causes the angle between the puncture tip 11 and the imaging tip 21 to change. When the distance between the abutment member 31 and the imaging tip 21 gradually decreases, the angle between them also gradually decreases, resulting in a smaller puncture angle. Conversely, when the distance between the abutment member 31 and the imaging tip 21 gradually increases, the angle between them also gradually increases, resulting in a larger puncture angle. The push-pull component 32 can adjust the degree of push-pull of the abutment component 31, so that the angle between the puncture tip 11 and the imaging tip 21 can be adjusted to a suitable degree, so that the puncture tip 11 can be accurately inserted into the lesion tissue for sampling or ablation, while avoiding blood vessels or nerves to prevent bleeding or infection in the patient.

[0036] Figure 2 This is a schematic diagram comparing the puncture effect of the imaging puncture combination device provided in the embodiments of this application before and after angle adjustment, as shown in the figure. Figure 2 As shown at point A, before angle adjustment, the angle between the puncture tip 11 and the imaging tip 21 was small, and the puncture angle was also small, resulting in deviation and failure to insert the puncture into the lesion tissue 40. Figure 2 As shown at point B, after the angle is adjusted, the angle between the puncture tip 11 and the imaging tip 21 increases, the puncture angle increases, and it can be accurately inserted into the lesion tissue 40.

[0037] The imaging puncture combination device provided in this application can be used once or multiple times. By integrating the puncture device and the imaging device into one unit, both devices can be inserted into the endoscope simultaneously. The imaging tip of the imaging device can reflect in real time whether the puncture tip is accurately inserted into the target tissue to be sampled or ablated. If the image shows an insertion deviation, the angle between the puncture tip and the imaging tip can be adjusted in real time using the angle adjustment component, so that the puncture tip is close to the lesion tissue before sampling or ablation, thereby achieving precise sampling or ablation. That is, the device of this application can perform real-time positioning and real-time angle adjustment, eliminating the need for multiple positioning before sampling or ablation, thus simultaneously improving accuracy and reducing cost.

[0038] In one embodiment, the puncture device 10 includes a puncture tube 101 and a puncture instrument 102, and the imaging device 20 includes an imaging tube 201 and an imaging instrument 202. The puncture tube 101 and the imaging tube 201 are fixedly connected, and the puncture instrument 102 can move in and out of the puncture tube 101, and the imaging instrument 202 can move in and out of the imaging tube 201.

[0039] like Figure 1 As shown, at least one first instrument channel 1 is formed inside the puncture conduit 101. Each first instrument channel 1 can accommodate the insertion of one puncture instrument 102, which specifically includes a biopsy instrument or an ablation instrument. The puncture tip 11 includes a bending section 1011 at the front end of the puncture conduit 101, and the portion of the puncture instrument 102 located at and extending beyond the bending section 1011. The insertion of the puncture tip 11 into the lesion tissue mentioned above specifically refers to the insertion of the portion of the puncture instrument 102 extending beyond the bending section 1011 into the lesion tissue. When adjusting the angle, the angle between the bending section 1011 and the imaging front end 21 changes, thereby changing the puncture angle of this portion of the puncture instrument 102.

[0040] By providing the puncture channel 101, the puncture instrument 102 can only touch the puncture channel 101 when passing through the endoscope, without damaging the endoscope. Furthermore, by providing two or more first instrument channels 1, the puncture instruments 102 will not interfere with each other when used simultaneously. In other words, the structure of the puncture device 10 in this application can extend the service life of the endoscope and each puncture instrument 102, reducing surgical costs.

[0041] like Figure 1 As shown, a second instrument channel 2 is formed inside the imaging conduit 201. The second instrument channel 2 can accommodate an imaging instrument 202. The imaging instrument 202 is preferably an ultrasound probe, which can acquire images through the principle of ultrasound imaging. Of course, the imaging instrument 202 can also be other devices with imaging functions, such as OCT (Optical Coherence Tomography) devices. Taking the ultrasound probe as an example, the imaging instrument 202 includes an imaging mechanism 2021 and a driving mechanism 2022. The imaging mechanism 2021 can acquire ultrasound images in real time under the drive of the driving mechanism 2022. The imaging front end 21 includes the part of the imaging mechanism 2021 that extends out of the imaging conduit 201.

[0042] By setting up the imaging conduit 201, the imaging device 202 can be used more flexibly. The imaging device 202 can be inserted when needed, and can be left uninserted or replaced with other medical devices when not needed. Compared with the method of directly fixing the imaging device 202 to the puncture device 10, the flexible setting method of this application can be applied to more scenarios and is more practical.

[0043] In one embodiment, the abutting member 31 includes a bottom surface 301 and a top surface 302. The bottom surface 301 abuts against the imaging conduit 201, and the top surface 302 abuts against the puncture conduit 101. In a first direction near the imaging front end 21, the height of the top surface 302 from the bottom surface 301 gradually increases.

[0044] like Figure 3 The diagram shown is a structural schematic of the angle adjustment component provided in this embodiment. The abutment member 31 includes a bottom surface 301 and a top surface 302. The bottom surface 301 is a plane and abuts against the imaging conduit 201, while the top surface 302 is an inclined surface and abuts against the puncture conduit 101. In the first direction near the imaging front end 21, that is... Figure 1 and Figure 3 From bottom to top, the height of the top surface 302 from the bottom surface 301 gradually increases, forming an inclined surface.

[0045] like Figure 4 The diagram shows the adjustment principle of the angle adjustment component provided in this application embodiment. When the abutting member 31 moves forward along the axial direction, the point where the bending part 1011 abuts with the highest point of the top surface 302 is point F. At this time, the height of point F from the bottom surface 301 is equal to the height h1 of the highest point of the top surface 302 from the bottom surface 301. When the abutting member 31 moves backward along the axial direction, the point where the bending part 1011 abuts with the highest point of the top surface 302 becomes point G. At this time, the height of point G from the bottom surface 301 is equal to h1. Since the height of the top surface 302 from the bottom surface 301 gradually increases in the direction close to the imaging front end 21, the height h2 of point F from the bottom surface 301 is greater than h1. Therefore, the bending degree of the puncture front end 11 increases, which makes the included angle between the puncture front end 11 and the imaging front end 21 larger. By setting the top surface 302 as an inclined plane, and increasing its height as it gets closer to the imaging front end 21, the angle between the puncture front end 11 and the imaging front end 21 can be flexibly adjusted simply by pushing and pulling the abutment component 31. This facilitates the doctor's operation, reduces surgical time, lowers surgical risks, and enables precise diagnosis and treatment.

[0046] In one embodiment, the push-pull assembly 32 includes a guide rail 321, a sliding member 322, and a control mechanism 323. The guide rail 321 is disposed between the puncture tube 101 and the imaging tube 201 and is fixedly connected to the puncture tube 101 and the imaging tube 201. The guide rail 321 includes an axial groove 300. The abutment member 31 is located outside the guide rail 321 and is fixedly connected to the sliding member 322. Under the control of the control mechanism 323, the sliding member 322 slides along the groove 300 in the guide rail 321.

[0047] like Figure 1 As shown, the control mechanism 323 can be a control handle, manually operated by relevant personnel, or an electronic control module, automatically operated according to relevant instructions. Combined with... Figure 1 and Figure 3 As shown, the bottom surface of the guide rail 321 is fixedly connected to the imaging conduit 201, and the top surface is fixedly connected to the puncture conduit 101. A groove 300 is formed in the guide rail 321, and the groove 300 is arranged along the axial direction of the imaging device 20. A sliding member 322 is disposed in the groove 300 and can slide back and forth along the groove 300 under the control of the control mechanism 323. The abutment member 31 is located outside the guide rail 321 and is fixedly connected to the sliding member 322. When the control mechanism 323 controls the sliding member 322 to slide along a second direction away from the imaging front end 21 (… Figure 1 and Figure 3 When the sliding member 322 slides in the direction from top to bottom, the abutment member 31 will also be driven to slide in the same way. Conversely, when the control mechanism 323 controls the sliding member 322 to slide in the first direction close to the imaging front end 21 ( Figure 1 and Figure 3 When sliding from bottom to top, the abutment member 31 will also be driven to slide in the same way.

[0048] like Figure 3 As shown, the guide rail 321 can be a cuboid, with grooves 300 formed on its bottom and top surfaces, and the two grooves 300 are interconnected. The sliding member 322 is dumbbell-shaped, including a first sliding part, a second sliding part, and a connecting part located between the two. The first sliding part slides along the groove 300 formed on the top surface, and the second sliding part slides along the groove 300 formed on the bottom surface. The two ends of the groove serve as limiting points, and the shapes of the two ends of the groove match the shapes of the first and second sliding parts. For example, if the two ends of the groove are semicircular, the first and second sliding parts are both circular with equal radii, and when sliding to the two ends, the circles and semicircles engage; or if the two ends of the groove are rectangular, the first and second sliding parts are also rectangular with equal widths, and when sliding to the two ends, they also engage.

[0049] It should be noted that, Figure 3The structure of the guide rail 321 and the sliding member 322 is merely illustrative and is not intended to limit the scope of this application. For example, the guide rail 321 may consist of only two opposing strips, each strip having its bottom surface fixedly connected to the imaging conduit 201 and its top surface fixedly connected to the puncture conduit 101. Each strip has a groove 300, and the two ends of the sliding member 322 move axially within the two grooves 300 respectively. Those skilled in the art can modify the structure of the guide rail 321 and the sliding member 322 as needed, as long as the sliding member 322 can slide back and forth axially within the grooves 300.

[0050] In one embodiment, the push-pull assembly 32 further includes a traction member 324, the first end of which is connected to the control mechanism 323, and the second end of which is connected to the sliding member 322. When the control mechanism 323 pulls the traction member 324, the abutment member 31 slides in a second direction away from the imaging front end 21.

[0051] Combination Figure 1 and Figure 3 As shown, the two ends of the traction member 324 are respectively connected to the sliding member 322 and the control mechanism 323. The control mechanism 323 can apply a pulling force to the traction member 324, thereby driving the sliding member 322 to slide in the slide groove 300 along the second direction, and finally causing the abutment member 31 to slide as well. The second direction is the direction away from the imaging front end 21, that is... Figure 1 and Figure 3 The direction is from top to bottom. The traction component 324 can be a steel wire. The first end of the steel wire can be fixed in the control handle. By operating the control handle, a part of the steel wire located outside the control handle can be wound into the control handle to pull the sliding component 322. This method is simple and convenient, and easy for doctors to operate.

[0052] In one embodiment, the push-pull assembly 32 further includes a reset member 325, which resets the abutment member 31 along a first direction close to the imaging front end 21 when the control mechanism 323 stops pulling the traction member 324.

[0053] The control mechanism 323 is located on the side away from the imaging front end 21. In the initial state, the abutment member 31 is in the first position, at which point the distance between the abutment member 31 and the imaging front end 21 is minimal. When the control mechanism 323 pulls the traction member 324, it causes the abutment member 31 to slide along the second direction. As it is pulled, the distance between the abutment member 31 and the imaging front end 21 gradually increases until it slides to the second position, at which point the distance between the abutment member 31 and the imaging front end 21 is maximum. When the control mechanism 323 stops pulling the traction member 324, the reset member 325 can reset the abutment member 31 along the first direction, which refers to the direction closer to the imaging front end 21. Figure 1The middle finger moves from bottom to top, and the contact member 31 gradually resets under the action of the reset member 325, and the distance between it and the imaging front end 21 gradually decreases until it is reset to the first position.

[0054] This application, by setting a reset component 325, allows the abutment component 31 to be automatically reset simply by stopping the pulling of the traction component 324 and releasing the traction component 324 when it is necessary to push the abutment component 31. This makes the pushing process simpler and faster. The imaging device 20 acquires ultrasound images in real time, and the control mechanism 323 adjusts parameters such as the magnitude of the pulling force, the timing of the pulling force application, and the timing of the pulling force release in real time according to the images. Under the combined action of the control mechanism 323 and the reset component 325, the abutment component 31 can be stopped at any position between the first position and the second position, where the optimal puncture angle can be achieved.

[0055] In one embodiment, the reset member 325 is a spring, which is sleeved outside the traction member 324 and located inside the slide groove 300.

[0056] like Figure 3 As shown, the reset component 325 can specifically be a spring, which is sleeved on the outside of the traction component 324 and located only within the slide groove 300. When the control mechanism 323 pulls the traction component 324, the abutment component 31 slides along the second direction, and the spring is compressed. When the control mechanism 323 stops pulling the traction component 324, the spring will rebound from the compressed state, and the force generated by the rebound can reset the abutment component 31. By setting the spring as the reset component 325, automatic reset can be achieved solely through the rebound force, which is simple and easy to operate.

[0057] In one embodiment, the push-pull assembly 32 further includes a protective sleeve 326, which is sleeved on the outside of the traction member 324 and located between the guide rail 321 and the control mechanism 323. The protective sleeve 326 is fixedly connected to the puncture tube 101 and the imaging tube 201.

[0058] Combination Figure 1 and Figure 3 As shown, the protective sleeve 326 is fixedly connected to the puncture tube 101 and the imaging tube 201. When the control mechanism 323 pulls the traction mechanism 324, the protective sleeve 326 will not be pulled along with it, thus preventing the traction component 324 from directly contacting the endoscope during the pulling process and causing damage to the endoscope, thereby improving safety. The protective sleeve 326 can be fixed by adhesive bonding.

[0059] In one embodiment, the push-pull assembly 32 further includes a fixing tube 327, through which the abutting member 31 and the sliding member 322 are fixedly connected.

[0060] like Figure 3As shown, the abutting member 31 is disposed outside the guide rail 321, and the sliding member 322 is disposed inside the guide rail 321. The two need to be fixedly connected by the fixing tube 327. The guide rail 321 has a connection hole on the side near the imaging front end 21. The fixing tube 327 can pass through the connection hole to connect with the abutting member 31 and the sliding member 322 respectively.

[0061] It should be noted that, Figure 3 The connection method of the abutting member 31 and the sliding member 322 is only an illustration and is not limited to this application. For example, the abutting member 31 and the sliding member 322 can also be integrally formed. Those skilled in the art can set the connection method of the abutting member 31 and the sliding member 322 as needed, as long as they can slide synchronously.

[0062] In one embodiment, the length of the bending section 1011 is no greater than 2 cm and no less than 1 cm. If the bending section 1011 is too long, the angle between the puncture tip 11 and the imaging tip 21 does not change significantly during the movement of the abutment member 31, resulting in a longer angle adjustment time and lower efficiency. If the bending section 1011 is too short, the angle change during the movement of the abutment member 31 will be larger, making it difficult to control the angle adjustment accuracy. Therefore, this application preferably specifies that the length of the bending section 1011 is no greater than 2 cm and no less than 1 cm. Within this length range, both the efficiency and accuracy of angle adjustment can be guaranteed.

[0063] In one embodiment, when the imaging device 202 is an ultrasonic mini-probe, the ultrasonic mini-probe includes an outer sheath 20a, the outer sheath 20a includes an imaging window 20b, and the puncture tip 11 is located within the imaging range of the imaging window 20b.

[0064] like Figure 5 As shown, the ultrasound mini-probe includes an outer sheath 20a, a transducer 20c, a spring tube (not shown), and a signal line (not shown). The transducer 20c, spring tube, and signal line are all located inside the outer sheath 20a. The outer sheath 20a has a transparent imaging window 20b. The transducer 20c is mounted at the location of the imaging window 20b via a metal sheath 20d. One end of the spring tube is connected to the metal sheath 20d, and the other end is connected to a drive mechanism 2022 (not shown). The drive mechanism 2022 drives the spring tube to rotate within the outer sheath 20a, thereby rotating the transducer 20c and achieving ultrasound imaging. After the ultrasound mini-probe extends out of the imaging tube 201, the puncture tip 11 is located within the imaging range of the imaging window 20b. During the angle adjustment of the puncture tip 11, the positional relationship between the puncture instrument 102 and the lesion tissue can be detected by the ultrasound mini-probe in real time and with precision, providing a relatively comprehensive reference for determining the optimal puncture angle.

[0065] In one embodiment, the imaging puncture assembly further includes a housing 50, a control mechanism 323, a puncture conduit 101, and an imaging conduit 201 that are detachably connected to the inner wall of the housing 50, the housing 50 including a first opening, a second opening, a third opening, and a fourth opening, the front ends of the puncture conduit 101 and the imaging conduit 201 facing the first opening, the rear ends of the puncture conduit 101 facing the second opening, the rear ends of the imaging conduit 201 facing the third opening, and the operating area of ​​the control mechanism 323 facing the fourth opening.

[0066] like Figure 6 As shown, the housing 50 of the imaging puncture assembly is used to enclose the exposed components to form a complete product. The control mechanism 323 (not shown), the puncture tube 101, and the imaging tube 201 are all detachably connected to the inner wall of the housing 50. During connection, a buckle 60 can be provided on the inner wall of the housing 50, allowing the puncture tube 101 and imaging tube 201 to be secured to the housing 50. The housing 50 includes a first opening, a second opening, a third opening, and a fourth opening. The front ends of the puncture tube 101 and the imaging tube 201 face the first opening, allowing the puncture instrument 102 to extend from the first instrument channel 1 through the first opening for puncture, and the imaging instrument 202 to extend from the second instrument channel 2 through the first opening for imaging. With the rear end of the puncture tube 101 facing the second opening, the puncture instrument 102 can be inserted into the first instrument channel 1 from the second opening. With the rear end of the imaging tube 201 facing the third opening, the imaging instrument 202 can be inserted into the second instrument channel 2 from the third opening. With the operating area of ​​the control mechanism 323 facing the fourth opening, the operating area can be exposed from the fourth opening, and relevant personnel can perform various control operations in the operating area to realize the control function.

[0067] Before the bending section 1011 is bent, its front end is flush with the front end of the imaging conduit 201, both located within the housing 50. The housing 50 has a notch near the bending section 1011, located along its movement path, allowing the bending section 1011 to bend flexibly without obstruction. This design of the housing 50 provides both good product enclosure and ensures the normal operation of the bending function.

[0068] In one embodiment, the angle adjustment component includes a pre-bending member 33 disposed on the inner wall of the housing 50. The first end of the pre-bending member 33 is connected to the control mechanism 323, and the second end of the pre-bending member 33 is connected to the front end of the housing 50. The front end of the housing 50 is provided with a first opening. When the control mechanism 323 pulls the pre-bending member 33, the puncture front end 11 and the imaging front end 21 bend synchronously.

[0069] like Figure 6As shown, the pre-bending component 33 is disposed on the inner wall of the outer shell 50. Specifically, the pre-bending component 33 can be a bending wire. Multiple channels can be opened on the inner wall of the outer shell 50, and a bending wire is disposed in each channel. Figure 6 The diagram shows four channels and four bending wires, which are evenly distributed on the inner wall of the housing 50. The first end of each bending wire is connected to a control mechanism 323 (not shown), and the second end is connected to the front end of the housing 50, which is also the end with the first opening. When the control mechanism 323 pulls the first end of the bending wire, the second end of the bending wire causes the front end of the housing 50 to bend, thereby causing the puncture front end 11 and the imaging front end 21 to bend synchronously as a whole. When the control mechanism 323 pulls different bending wires, the entire structure bends in different directions, and the bending angle varies depending on the pulling force of the control mechanism 323. The control mechanism can control the object being pulled (one or more bending wires) and the pulling force, adjusting the bending direction and angle of the entire structure to a suitable state.

[0070] By setting the pre-bending component 33, the entire structure formed by the puncture tip 11 and the imaging tip 21 can be bent first, positioning it in a suitable location for obtaining lesion tissue, resulting in optimal imaging. Based on this, the abutment component 31 is then controlled to individually bend the puncture tip 11. These two bending operations allow for more precise positioning and puncture angle adjustments, leading to better imaging and sampling results.
