Description

Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to an ultrasonic endoscope system. Background Art

[0002] As the incidence of digestive and respiratory diseases increases year by year, endoscopic examination is particularly important for the diagnosis of diseases. The endoscopic ultrasound endoscope system can clearly screen for lesions of various layers of tissue below the digestive tract mucosa, such as tumors and cysts, and can obtain tomographic images of nearby organs such as the mediastinum, pancreas, bile duct and lymph nodes.

[0003] However, in traditional technical solutions, when performing tissue biopsy and tumor ablation treatment, a small ultrasound probe is used to observe the acquisition position first. Doctors need to remove the small ultrasound probe before sampling or ablation, and then insert the puncture needle or ablation needle. This process may lead to inaccurate positioning, especially in narrow areas or areas that cannot be directly observed by the endoscope, which increases the operation time and the risk of misdiagnosis.

[0004] BACKGROUND OF THE PRESENT APPLICATION The above information disclosed is only for understanding the background of the concept of the present application and may contain information that does not constitute the prior art. Summary of the invention

[0005] Based on this, it is necessary to provide an ultrasonic endoscope system to address the above problems.

[0006] An ultrasonic endoscopic system, comprising:

[0007] Bending device;

[0008] A catheter, the catheter comprising a first catheter and a second catheter, the first catheter being provided with an ultrasound imaging assembly, the second catheter being provided with an instrument channel, the distal end of the second catheter being provided with an outlet communicating with the instrument channel, the instrument channel being used for a puncture needle or an ablation needle to pass through, and the puncture needle or the ablation needle being able to extend from the outlet;

[0009] A plurality of traction ropes are embedded in the tube wall of the catheter, the proximal ends of the traction ropes are connected to the bending device, and the distal ends of the traction ropes are connected to the distal end of the catheter. The traction ropes can drive the catheter to bend under the drive of the bending device so that the outlet is aligned with the target tissue.

[0010] The above-mentioned ultrasonic endoscope system can at least achieve the following beneficial effects: the ultrasonic endoscope system realizes an efficient and accurate endoscopic inspection and treatment plan by integrating a bending adjustment device, a catheter, multiple traction ropes and an ultrasonic imaging component. First, the ultrasonic imaging component is located at the distal end of the first catheter, and can provide high-quality ultrasonic images in real time, which is conducive to the operator to observe the environment at the distal end of the catheter, so that the operator can operate under visual guidance and judge the relative position and distance between the puncture needle or ablation needle at the outlet of the instrument channel and the target tissue. There are multiple traction ropes in the catheter. When the outlet direction of the instrument channel needs to be adjusted, the operator can operate the bending adjustment device to drive the traction rope. The traction rope can flexibly adjust the bending direction of the catheter to ensure that the outlet of the instrument channel can accurately face the center position of the target tissue, so that the puncture needle or ablation needle extended from the outlet of the instrument channel can accurately hit the target tissue. This design enables the puncture needle or ablation needle to accurately act on the target tissue, such as ensuring that the puncture needle can accurately sample or the ablation needle can accurately ablate. The system not only improves the accuracy of diagnosis and treatment, but also significantly reduces operation time and the risk of misdiagnosis, improving the safety and efficiency of overall medical operations.

[0011] In some embodiments, the first catheter and the second catheter are at least partially connected, the proximal end of the second catheter is connected to the bending device, the distal end of the second catheter is formed with an outlet connected to the instrument channel, and a plurality of traction ropes are embedded in the tube wall of the second catheter, and the second catheter can be bent under the traction of the traction ropes so that the outlet is aligned with the target tissue. A plurality of traction ropes are embedded in the tube wall of the second catheter, so that the second catheter can be flexibly bent under the traction of the traction ropes, so as to accurately align the target tissue. This design enhances the maneuverability of the catheter, allowing the operator to more effectively adjust the direction and position of the catheter, ensuring that the outlet of the instrument channel can be accurately aligned with the target tissue, and improving the accuracy and efficiency of the operation. Through precise catheter bending and outlet positioning, the risk of misoperation is significantly reduced, the potential damage to the patient is reduced, and the safety and efficiency of the overall medical operation are improved.

[0012] In some embodiments, the first catheter and the second catheter are at least partially connected, the proximal end of the first catheter is connected to the bending device, and the plurality of traction ropes are embedded in the tube wall of the first catheter. The first catheter can drive the second catheter to bend under the traction of the traction ropes so that the outlet is aligned with the target tissue. A plurality of traction ropes are embedded in the tube wall of the first catheter. These traction ropes can accurately pull the first catheter through the control of the bending device, thereby driving the second catheter that is arranged parallel to the first catheter and fixed to each other to bend together. With this design, the operator can perform precise operations under the guidance of real-time imaging so that the outlet can be aligned with the target tissue.

[0013] In some embodiments, the distal ends of the first catheter and the second catheter are fixedly connected together. This means that the distal ends of the first catheter and the second catheter can move synchronously. Since the first catheter is equipped with an ultrasonic imaging component, this synchronous movement mechanism enables the ultrasonic imaging component at the distal end of the first catheter to better align with the target area for ultrasonic scanning, which can improve the accuracy and resolution of ultrasonic imaging, so that the operator can obtain clearer and more detailed images, thereby more effectively evaluating and diagnosing the target tissue.

[0014] In some embodiments, the catheter further comprises a fixed tube, a first catheter and a second catheter, the proximal end of the fixed tube is connected to the bending device, the fixed tube is sleeved at the distal ends of the first catheter and the second catheter, a plurality of traction ropes are embedded in the tube wall of the fixed tube, and the fixed tube can drive the first catheter and the second catheter to bend under the traction of the traction ropes, so that the outlet is aligned with the target tissue. The fixed tube is sleeved outside the first catheter and the second catheter, and its function is to provide structural support and stability for the entire catheter system. A plurality of traction ropes are embedded in the tube wall of the fixed tube, and these traction ropes can accurately pull the fixed tube through the control of the bending device, thereby driving the first catheter and the second catheter inside to bend together. Through this design, the outlet of the instrument channel can be aligned with the target tissue or the ultrasonic imaging component can be better fitted with the target tissue, achieving more accurate ultrasonic scanning and more accurate interventional operation. The advantage of this structure is that it combines the functions of ultrasonic imaging and instrument operation, allowing medical personnel to perform precise operations under the guidance of real-time imaging. The additional support provided by the fixed tube improves the stability and controllability of the catheter, thereby improving the efficiency and safety of the operation.

[0015] In some embodiments, the first catheter and the second catheter are integrally formed catheters, the traction rope is embedded in the tube wall of the catheter, the end of the first catheter is connected to an imaging catheter, and the imaging catheter is provided with an imaging window for imaging of the ultrasonic imaging component, and the catheter can be bent under the traction of the traction rope so that the outlet is aligned with the target tissue. The catheter adopts an integrally formed design and has good structural integrity and flexibility. The traction rope is embedded in the tube wall of the catheter. This design enables the catheter to be flexibly bent when traction is applied, so that the outlet of the catheter can be accurately aligned with the target tissue, thereby achieving a more efficient treatment effect.

[0016] In some embodiments, the ultrasonic endoscope system further includes an ultrasonic host and a guide wire, and a guide wire cavity is formed in the catheter, the guide wire cavity is independent of the instrument channel, the guide wire is arranged in the guide wire cavity, the proximal end of the guide wire is connected to the ultrasonic host, and the distal end of the catheter is connected to the ultrasonic imaging component. Two independent channels are formed in the catheter: one is the instrument channel for medical device operation, and the other is the guide wire cavity for accommodating the guide wire. The guide wire cavity and the instrument channel are independent of each other to ensure that the functions of the two do not interfere with each other. The guide wire is placed in the guide wire cavity, and its proximal end is connected to the ultrasonic host, and the distal end is connected to the ultrasonic imaging component of the catheter. This design allows ultrasonic signals to be transmitted between the ultrasonic host and the ultrasonic imaging component, thereby supporting real-time ultrasonic imaging. The advantage of this structure is that it can provide clear ultrasonic imaging guidance while performing interventional operations. The independence of the guide wire cavity ensures the safety and stability of the guide wire, and it will not be affected by the operation of the instrument, thereby improving the reliability and imaging quality of the system. Through this design, medical personnel can diagnose and treat more effectively, and improve the accuracy and safety of surgery.

[0017] In some embodiments, there are 2 or 4 traction ropes, and the multiple traction ropes are equally spaced along the circumference of the catheter. The equally spaced traction ropes ensure that the catheter can bend evenly under the action of traction. This uniformity is very important for the precise positioning and manipulation of the catheter, especially when it is necessary to operate at a specific target tissue. By adjusting the tension of different traction ropes, the operator can control the bending direction and angle of the catheter so that the outlet of the instrument channel at the distal end of the catheter can be accurately aligned with the target area. This design not only improves the flexibility and controllability of the catheter, but also increases the safety and efficiency of surgical operations. Medical personnel can perform interventional treatment or diagnostic operations more accurately with the assistance of real-time imaging or other guidance technologies.

[0018] In some embodiments, the ultrasonic endoscope system further includes a first developing member, the ultrasonic endoscope system further includes a first developing member, the first developing member is arranged in a ring at the distal end of the catheter, and the location of the first developing member is close to the outlet. The location of the first developing member is designed to be relatively close to the outlet of the catheter, the purpose is to provide a clear mark for the positioning of the puncture needle or ablation needle, which helps medical personnel to more intuitively confirm the position of the needle during the operation. Through the mark, the operator can judge the relative position and distance between the puncture needle / ablation needle and the target position, and can more accurately control the insertion angle and depth of the puncture needle / ablation needle, especially in medical operations that require high precision, such as tissue puncture sampling or ablation treatment. The design of the first developing member can have a variety of forms, such as development, color marking, raised structure or other visual markings, and the specific selection can be adjusted according to the surgical environment and operation requirements. This design not only improves the safety and accuracy of the operation, but also reduces the operation time to a certain extent and improves the overall treatment effect. By combining real-time ultrasound imaging and precise physical markings, the system provides more comprehensive support for clinical operations.

[0019] In some embodiments, the ultrasonic endoscope system further includes a second developing member, which is disposed on a side of the first catheter away from the second catheter, and the second developing member is a strip-shaped developing member, which is disposed at the distal end of the first catheter along the axis. The ultrasonic endoscope system further introduces a second developing member, which is located on a side of the distal end of the catheter away from the second catheter. The second developing member is disposed along the axis of the catheter, and its main purpose is to indicate the orientation of the puncture needle on the ultrasonic image. This design can provide additional visual references for medical personnel to help them more accurately determine the direction of the puncture needle. By clearly displaying the second developing member on the ultrasonic image, doctors can more intuitively understand the relative position of the puncture needle, thereby improving the accuracy and safety of the operation. The second developing member can be in the shape of a strip-shaped developing member to ensure that it can be clearly seen in ultrasonic imaging without interfering with other important image information. For example, in an ultrasonic examination, if the second developing member is on the same side as the target tissue, it means that the puncture needle is on the side away from the target tissue. At this time, the catheter needs to be rotated and adjusted. Through the position display of the second developing member, it can be adjusted to the same side as the target tissue to achieve accurate puncture biopsy. The introduction of the second developing part enables the ultrasonic endoscope system to provide higher operational flexibility and accuracy when performing puncture or other interventional operations.

[0020] In some embodiments, the second developing member is arranged corresponding to the outlet. This design ensures that the second developing member can accurately indicate the position of the catheter outlet, enhances the readability of the ultrasound image, and enables the doctor to quickly identify the relationship between the catheter outlet and the target tissue in real-time imaging. This is particularly important in complex anatomical environments and can help doctors perform safer and more effective operations in confined spaces. BRIEF DESCRIPTION OF THE DRAWINGS

An instrument channel is formed in the second catheter 220. An outlet 221 communicating with the instrument channel is formed at the distal end of the second catheter 220. The instrument channel is used for the puncture needle 900 or the ablation needle to pass through, and the puncture needle 900 or the ablation needle can extend from the outlet 221. The traction rope 300 may include but is not limited to a steel wire rope, a plurality of the traction ropes 300 are embedded in the tube wall of the catheter 200, the proximal end of the traction rope 300 is connected to the bending device 100, and the distal end of the traction rope 300 is connected to the distal end of the catheter 200, and the traction rope 300 can drive the catheter 200 to bend under the drive of the bending device 100, so that the outlet 221 is aligned with the target tissue 800. It should be noted that the proximal end and the distal end mentioned in this application are relative concepts, and the end close to the operator can be defined as the proximal end, and the end far from the operator can be defined as the distal end.

[0033] The above-mentioned ultrasonic endoscope system 10 can at least achieve the following beneficial effects: the ultrasonic endoscope system 10 realizes an efficient and accurate endoscopic inspection and treatment plan by integrating the bending adjustment device 100, the catheter 200, the plurality of traction ropes 300 and the ultrasonic imaging component 400. First, the ultrasonic imaging component 400 is located at the distal end of the first catheter 210, and can provide high-quality ultrasonic images in real time, which is conducive to the operator to observe the environment at the distal end of the catheter 200, so that the operator can operate under visual guidance and judge the relative position and distance between the puncture needle 900 or the ablation needle at the outlet 221 of the instrument channel and the target tissue 800. A plurality of traction ropes 300 are arranged in the catheter 200. When the direction of the outlet 221 of the instrument channel needs to be adjusted, the operator can operate the bending adjustment device 100 to drive the traction rope 300. The traction rope 300 can flexibly adjust the bending direction of the catheter 200 to ensure that the outlet 221 of the instrument channel can accurately face the center of the target tissue 800, so that the puncture needle 900 or the ablation needle extending from the outlet 221 of the instrument channel can accurately hit the target tissue 800.

The system not only improves the accuracy of diagnosis and treatment, but also significantly reduces the operation time and the risk of misdiagnosis, and improves the safety and efficiency of the overall medical operation.

[0034] See also Figure 6 In some embodiments, the first catheter 210 and the second catheter 220 are at least partially connected, the proximal end of the second catheter 220 is connected to the bending adjustment device 100, and the plurality of traction ropes 300 are embedded in the tube wall of the second catheter 220 and are arranged at equal intervals along the circumference of the second catheter 220, and the second catheter 220 can be bent under the traction of the traction ropes 300, so that the outlet 221 is aligned with the target tissue 800. The plurality of traction ropes 300 are embedded in the tube wall of the second catheter 220 and are arranged at equal intervals along the circumference thereof, so that the second catheter 220 can be flexibly bent under the traction of the traction ropes 300, so as to accurately align with the target tissue 800. This design enhances the maneuverability of the catheter 200, allows the operator to more effectively adjust the direction and position of the catheter 200, ensures that the outlet 221 of the instrument channel can accurately align with the target tissue 800, and improves the accuracy and efficiency of the operation. Through precise bending of the catheter 200 and positioning of the outlet 221, the risk of misoperation is significantly reduced, potential damage to the patient is reduced, and the safety and efficiency of the overall medical operation are improved.

[0035] In other embodiments, Figure 5As shown, the first catheter and the second catheter are at least partially connected, the proximal end of the first catheter 210 is connected to the bending adjustment device 100, and the plurality of traction ropes 300 are embedded in the tube wall of the first catheter 210 and are arranged at equal intervals along the circumference of the first catheter 210. The first catheter 210 can drive the second catheter 220 to bend under the traction of the traction ropes 300, so that the outlet 221 is aligned with the target tissue 800. The plurality of traction ropes 300 are embedded in the tube wall of the first catheter 210 and are arranged at equal intervals along the circumference thereof. These traction ropes 300 can accurately pull the first catheter 210 through the control of the bending adjustment device 100, thereby driving the second catheter 220 arranged in parallel with the first catheter 210 and fixed to each other to bend together. Through this design, the operator can perform precise operations under the guidance of real-time imaging, so that the outlet 221 can be aligned with the target tissue 800.

[0036] For example, the distal ends of the first catheter 210 and the second catheter 220 can be fixedly connected together. This means that the distal ends of the first catheter 210 and the second catheter 220 can move synchronously. Since the first catheter 210 is equipped with an ultrasonic imaging assembly 400, this synchronous movement mechanism enables the ultrasonic imaging assembly 400 at the distal end of the first catheter 210 to better align with the target area for ultrasonic scanning, which can improve the accuracy and resolution of ultrasonic imaging, so that the operator can obtain clearer and more detailed images, thereby more effectively evaluating and diagnosing the target tissue 800, and the bending of the second catheter 220 can also adjust the direction and position of the catheter 200, ensuring that the outlet 221 of the instrument channel can accurately align with the target tissue 800.

[0037] In other embodiments, the catheter 200 further includes a fixed tube (not shown), a first catheter 210 and a second catheter 220, wherein the fixed tube is connected to the bending device 100, the distal end of the first catheter 210 is connected to the ultrasonic imaging assembly 400, the instrument channel is formed in the second catheter 220, and the distal end of the second catheter 220 is formed with an outlet 221 communicating with the instrument channel, the fixed tube is sleeved at the distal ends of the first catheter 210 and the second catheter 220, a plurality of traction ropes 300 are embedded in the tube wall of the fixed tube and are arranged at equal intervals along the circumference of the fixed tube, and the fixed tube can drive the first catheter 210 and the second catheter 220 to bend under the traction of the traction rope 300, so that the outlet 221 is aligned with the target tissue 800 or the ultrasonic imaging assembly 400 can better fit the target tissue 800, so as to achieve more accurate ultrasonic scanning. The fixed tube is sleeved outside the first catheter 210 and the second catheter 220, and its function is to provide structural support and stability for the entire catheter 200 system. A plurality of traction ropes 300 are embedded in the wall of the fixed tube and are arranged at equal intervals along the circumference thereof. These traction ropes 300 can accurately pull the fixed tube through the control of the bending device 100, thereby driving the first catheter 210 and the second catheter 220 inside to bend together. Through this design, the outlet 221 of the instrument channel can be aligned with the target tissue 800 to achieve more precise interventional operations. The advantage of this structure is that it combines the functions of ultrasonic imaging and instrument operation, allowing medical personnel to perform precise operations under the guidance of real-time imaging. The additional support provided by the fixed tube improves the stability and controllability of the catheter 200, thereby improving the efficiency and safety of the operation.

[0038] In other embodiments, the first catheter 210 and the second catheter 220 are integrally formed catheters, the traction rope 300 is embedded in the tube wall of the catheter 200, the end of the first catheter 210 is connected to an imaging catheter, and the imaging catheter is provided with an imaging window for imaging of the ultrasonic imaging component 400, and the catheter 200 can be bent under the traction of the traction rope 300 so that the outlet is aligned with the target tissue. The catheter 200 adopts an integrally formed design and has good structural integrity and flexibility. The traction rope 300 is embedded in the tube wall of the catheter 200. This design enables the catheter 200 to bend flexibly when traction is applied, which not only enables the ultrasonic imaging component 400 to fit the target tissue more closely for ultrasonic detection, but also enables the outlet of the catheter 200 to be accurately aligned with the target tissue, thereby achieving a more efficient treatment effect.

[0039] See also Figure 4In some embodiments, the proximal end of the catheter 200 is formed with an inlet 222 connected to the instrument channel, and the inlet 222 is used for the puncture needle 900 or the ablation needle to extend into the instrument channel.

[0040] See also Figure 5 In some embodiments, the ultrasonic endoscope system 10 further includes a first developing member 710, which is disposed around the distal end of the catheter 200, and the first developing member 710 is located close to the outlet 221. The first developing member 710 is designed to be located relatively close to the outlet 221 of the catheter 200, in order to provide a clear mark for the positioning of the puncture needle 900 or the ablation needle, which helps medical personnel to more intuitively confirm the position of the needle during the operation. Through the mark, the operator can determine the relative position and distance between the puncture needle 900 / ablation needle and the target position, and can more accurately control the insertion angle and depth of the puncture needle 900 / ablation needle, especially in medical operations that require high precision, such as tissue puncture sampling or ablation therapy. The design of the first developing member 710 can be in various forms, such as developing or other visual marks, and the specific selection can be adjusted according to the surgical environment and operation requirements. This design not only improves the safety and accuracy of the operation, but also reduces the operation time to a certain extent and improves the overall treatment effect. By combining real-time ultrasound imaging and precise physical markings, the system provides more comprehensive support for clinical operations.

[0041] Specifically, Figure 7As shown, in some embodiments, the ultrasonic endoscope system 10 further includes a second developing member 720, which is disposed on a side of the first catheter 210 away from the second catheter 220, and the second developing member 720 is a strip-shaped developing member, which is disposed at the distal end of the first catheter 210 along the axis. The second developing member 720 is disposed along the axis of the catheter 200, and its main purpose is to indicate the orientation of the puncture needle 900 on the ultrasonic image. This design can provide additional visual references for medical personnel, helping them to more accurately determine the direction of the puncture needle 900. By clearly displaying the second developing member 720 on the ultrasonic image, the doctor can more intuitively understand the relative position of the puncture needle 900, thereby improving the accuracy and safety of the operation. The second developing member 720 can be in the shape of a strip-shaped developing member to ensure that it can be clearly seen in ultrasonic imaging without interfering with other important image information. For example, during ultrasound examination, if the second developing member 720 is on the same side as the target tissue, it means that the puncture needle 900 is located on the side away from the target tissue 800. At this time, the catheter needs to be rotated and adjusted. Through the position display of the second developing member 720, it can be adjusted to the same side as the puncture needle 900 and the target tissue 800 to achieve accurate puncture biopsy. The introduction of the second developing member 720 enables the ultrasonic endoscope system to provide higher operational flexibility and accuracy when performing puncture or other interventional operations.

[0042] More specifically, in some embodiments, the second developing member 720 is disposed corresponding to the outlet 221. This design ensures that the second developing member 720 can accurately indicate the position of the outlet of the catheter 200, enhances the readability of the ultrasound image, and enables the doctor to quickly identify the relationship between the outlet of the catheter 200 and the target tissue in real-time imaging. This is particularly important in complex puncture biopsies, and can help doctors perform safer and more effective operations in a narrow space.
