Description

Technical Field

[0001] This invention relates to the field of ultrasonic catheter replacement technology, and more specifically, to a replaceable transducer ultrasonic catheter. Background Technology

[0002] Intracardiac ultrasound (ICE) is an important imaging technique. It provides high-resolution real-time visualization of cardiac structures and helps monitor catheter position and identify complications. Patients experience less radiation exposure during procedures and do not require general anesthesia. With these advantages, ICE has become the ideal imaging modality for many procedures, including atrial septal defect closure, catheter ablation for arrhythmias, and left atrial appendage closure. ICE technology is increasingly being widely used in various interventional procedures.

[0003] In response, Chinese patent application publication number CN116350272A discloses a replaceable transducer ultrasound catheter, relating to the field of replaceable transducer ultrasound catheter technology. The key technical points include: a catheter structure and a transducer structure. The catheter structure is sleeved outside the replaceable transducer structure, and the transducer structure, in conjunction with the catheter structure, is used by doctors to perform surgical procedures on patients. The advantage of this replaceable transducer ultrasound catheter is that, through the design of a disposable catheter structure and a replaceable transducer structure, part of the transducer in the ultrasound catheter can be reused, and the shape of the ultrasound catheter is not affected by the usage scenario. This helps to reduce the product's usage cost and the expense of surgery.

[0004] However, in practical use, the transducer installation is quite cumbersome, making it difficult to quickly install the transducer into the catheter. Furthermore, the sealing effect on the balloon is poor, and the catheter needs to be manually removed and replaced after use, as it cannot automatically detach from the transducer, thus limiting its replacement capabilities. Therefore, addressing and improving these issues is an urgent problem to be solved.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a replaceable transducer ultrasonic catheter. Summary of the Invention

[0007] To achieve the above objectives, the present invention provides the following technical solution: a replaceable transducer ultrasonic conduit, comprising a mounting ring, an mounting tube mounted on the left side of the mounting ring, a transducer mounting cylinder mounted on the left side of the mounting tube, a conduit body disposed on the outer surface of the transducer mounting cylinder, and a sealing groove and a mounting groove sequentially formed from top to bottom on the left side interior of the conduit body.

[0008] An adapter ring is installed inside the transducer mounting cylinder. The adapter ring and the mounting groove are mutually adapted. The transducer body is installed on the left side of the adapter ring. The transducer body and the mounting groove are mutually adapted. A magnetic ring is installed inside the sealing groove.

[0009] An iron ring is installed on the left side surface of a magnetic ring, and the magnetic ring and the iron ring are magnetically attracted to each other. A connecting ring is installed on the outer surface of the iron ring, and a balloon body is installed on the outer surface of the connecting ring. An installation hole is opened on the top surface of the connecting ring. An air pump pipe is installed on the outer surface of the transducer mounting cylinder, and the air pump pipe is compatible with the installation hole.

[0010] Preferably, the inside of the conduit body is provided with a through groove, and the through groove is adapted to the transducer mounting cylinder.

[0011] Preferably, the outer surface of the catheter body is connected to a mounting ring, and the right side surface of the mounting ring is provided with an insertion hole.

[0012] Preferably, positioning blocks are installed on both the upper and lower surfaces of the mounting ring, the positioning blocks have stabilizing grooves inside, and insertion posts are inserted into the insertion holes.

[0013] Preferably, a spring body is installed inside the stabilizing groove, and the spring body is mounted on the inner wall of the positioning block.

[0014] Preferably, connecting blocks are installed on both the upper and lower surfaces of the mounting ring, and a stabilizing column is installed on the left side of the connecting block, with the stabilizing column and the stabilizing groove being mutually compatible.

[0015] Preferably, a support frame is installed on the top surface of the connecting block, and a connecting plate is installed on the left side of the support frame.

[0016] Preferably, a stop plate is slidably installed inside the connecting plate, and a stabilizing block is fixedly connected to the right side surface of the stop plate, with the right side surface of the stop plate abutting against the left side surface of the positioning block.

[0017] Preferably, a guide ring is installed on the outer surface of the catheter body, a telescopic cylinder is provided on the right side surface of the guide ring, and the end of the telescopic cylinder away from the guide ring is installed on the left side surface of the mounting ring.

[0018] Preferably, the insertion post is installed on the left side surface of the mounting ring, and the insertion post and the insertion hole are mutually adapted to each other.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In this invention, through the installation ring, installation tube, transducer installation cylinder, conduit body, installation groove, adapter ring, transducer body, sealing groove, magnetic ring, iron ring, connecting ring, balloon body, installation hole, suction pump tube, through groove, and installation ring, during installation, the adapter ring and transducer body are first installed into the installation groove in sequence, and then the iron ring is installed into the sealing groove. At this time, the magnetic ring and the iron ring are magnetically attracted to each other, and the overall connection is relatively stable. At the same time, the connecting ring is fixedly connected to the balloon body, so that the balloon body can seal the entire installation groove. When the connecting ring is installed into the sealing groove, the suction pump tube and the installation hole are fixedly connected. The mounting holes are mutually compatible, and the air inside the connecting ring and the balloon body can be automatically discharged through the air pump pipe. As a result, the balloon body will fit against the outer surface of the transducer mounting cylinder, and the overall sealing effect of the transducer body is good. Therefore, the overall installation operation is relatively simple and the sealing effect is good. Then, the transducer mounting cylinder is installed into the inside of the mounting groove, thus completing the installation between the conduit body and the transducer mounting cylinder. Subsequently, the right side of the mounting ring will abut against the left side of the mounting ring, and then the insertion post will be inserted into the inside of the insertion hole. Thus, the overall installation between the transducer mounting cylinder and the conduit body is relatively stable, which reflects the functionality of the design.

[0021] 2. In this invention, through the arrangement of a spring body, connecting block, stabilizing column, support frame, connecting plate, abutment plate, stabilizing block, and guide ring, after the mounting ring and mounting ring are stabilized by mutual contact, the stabilizing column is inserted into the stabilizing groove. Then, the left surface of the stabilizing column abuts against the right surface of the spring body, thereby squeezing the spring body. Subsequently, the right surface of the positioning block abuts against the left surface of the connecting block. After the positioning block and connecting block are connected, the abutment plate is pushed downward inside the connecting plate, so that the right surface of the abutment plate fits against the left surface of the positioning block. Therefore, the position of the positioning block and connecting block after installation can be stabilized, and the overall stabilization effect is good. After the operation is completed, by holding the stabilizing block and pulling the abutment plate upward, the abutment plate will release the positioning block and the connecting block. The limiting effect of the connecting block is such that when the positioning block and connecting block are released from their limiting effects, the elastic design of the spring body automatically pushes the positioning block to the left. As the positioning block moves to the left, the mounting ring and the entire catheter body also move to the left, automatically separating the catheter body from the transducer mounting cylinder. This avoids the previous manual separation method. The mounting ring can be unscrewed from the outer surface of the catheter body for recycling. The mounting ring is then connected to the guide ring via a telescopic cylinder. The guide ring's design limits the position of the catheter body, facilitating surgical use. This design automatically separates the catheter body from the transducer mounting cylinder, making it easy to replace the transducer mounting cylinder. The operation is simple, demonstrating the ingenuity of the design. Attached Figure Description

[0033] like Figure 1-9As shown, the present invention provides a replaceable transducer ultrasonic conduit, including a mounting ring 1, a mounting tube 2 mounted on the left side of the mounting ring 1, a transducer mounting cylinder 3 mounted on the left side of the mounting tube 2, a conduit body 4 provided on the outer surface of the transducer mounting cylinder 3, and a sealing groove 8 and a mounting groove 5 sequentially formed on the left side interior of the conduit body 4 from top to bottom.

[0034] The adapter ring 6 is installed inside the transducer mounting cylinder 3. The adapter ring 6 and the mounting groove 5 are mutually adapted. The transducer body 7 is installed on the left side of the adapter ring 6. The transducer body 7 and the mounting groove 5 are mutually adapted. The magnetic ring 9 is installed inside the sealing groove 8. The mounting tube 2 is equipped with a cable, which is connected to the transducer body 7 through the cable.

[0035] Iron ring 10 is installed on the left side of magnetic ring 9, and magnetic ring 9 and iron ring 10 are magnetically attracted to each other. A connecting ring 11 is installed on the outer surface of iron ring 10, and a balloon body 12 is installed on the outer surface of connecting ring 11. A mounting hole 13 is opened on the top surface of connecting ring 11. An air pump pipe 14 is installed on the outer surface of transducer mounting cylinder 3, and the air pump pipe 14 is adapted to the mounting hole 13. A through groove 15 is opened inside the conduit body 4, and the through groove 15 is adapted to the transducer mounting cylinder 3. A mounting ring 16 is connected to the outer surface of conduit body 4. An insertion hole 17 is opened on the right side surface of mounting ring 16. Positioning blocks 18 are installed on both the upper and lower surfaces of mounting ring 16. A stabilizing groove 19 is opened inside the positioning block 18. An insertion post 20 is inserted into the insertion hole 17. During installation, first, the adapter ring 6 and transducer body 7 are installed into the mounting groove 5 in sequence, and then the iron ring 10 is installed into the sealing groove 8. At this time, the magnetic ring 9 and iron ring 10 are magnetically attracted to each other. The rings 10 are magnetically attracted to each other, and the overall connection is relatively stable. At the same time, the connecting ring 11 is fixedly connected to the balloon body 12, so that the balloon body 12 can seal the overall mounting groove 5. When the connecting ring 11 is installed inside the sealing groove 8, the air pump pipe 14 and the mounting hole 13 are adapted to each other. Then, the air pump pipe 14 can automatically discharge the air inside the connecting ring 11 and the balloon body 12, so that the balloon body 12 will fit against the outer surface of the transducer mounting cylinder 3, and the overall sealing effect of the transducer body 7 is good. Therefore, the overall installation is relatively simple and the sealing effect is good. Then, the transducer mounting cylinder 3 is installed into the mounting groove 5, so that the installation between the conduit body 4 and the transducer mounting cylinder 3 is completed. Then, the right side of the mounting ring 16 will abut against the left side of the mounting ring 1, and then the insertion post 20 will be inserted into the insertion hole 17, so that the overall installation between the transducer mounting cylinder 3 and the conduit body 4 is relatively stable.

[0036] A spring body 21 is installed inside the stabilizing groove 19. The spring body 21 is mounted on the inner wall of the positioning block 18. Connecting blocks 22 are installed on both the upper and lower surfaces of the mounting ring 1. A stabilizing column 23 is installed on the left side of the connecting block 22. The stabilizing column 23 is compatible with the stabilizing groove 19. A support frame 24 is installed on the top surface of the connecting block 22. A connecting plate 25 is installed on the left side of the support frame 24. A stop plate 26 is slidably installed inside the connecting plate 25. A stabilizing block 27 is fixedly connected to the right side surface of the stop plate 26. The right side surface of the stop plate 26 abuts against the left side surface of the positioning block 18. A guide is installed on the outer surface of the conduit body 4. A telescopic cylinder 29 is provided on the right side surface of ring 28 and guide ring 28. The end of telescopic cylinder 29 away from guide ring 28 is installed on the left side surface of mounting ring 16. After mounting ring 16 and mounting ring 1 are in stable contact, stabilizing column 23 is inserted into the inside of stabilizing groove 19. Then, the left side surface of stabilizing column 23 abuts against the right side surface of spring body 21, thereby squeezing spring body 21. Subsequently, the right side surface of positioning block 18 abuts against the left side surface of connecting block 22. After positioning block 18 and connecting block 22 are connected, the abutment plate 26 is pushed downward inside connecting plate 25. Thus, the right surface of the abutment plate 26 will adhere to the left surface of the positioning block 18, thereby stabilizing the position of the positioning block 18 and the connecting block 22 after installation, resulting in good overall stability. After the surgery, by holding the stabilizing block 27 and pulling the abutment plate 26 upwards, the abutment plate 26 will release the limiting effect of the positioning block 18 and the connecting block 22. After the positioning block 18 and the connecting block 22 are released from their limiting effect, the elastic design of the spring body 21 will automatically push the positioning block 18 to the left. As the positioning block 18 moves to the left, the mounting ring 16 and the catheter body... The entire body 4 will also be pushed to the left, thereby automatically separating the catheter body 4 from the transducer mounting cylinder 3, avoiding the previous manual separation. At the same time, the mounting ring 16 can be unscrewed from the outer surface of the catheter body 4 for recycling. Then, the mounting ring 16 is connected to the guide ring 28 through the telescopic cylinder 29. The design of the guide ring 28 can limit the position of the catheter body 4, making it convenient for surgical use. Thus, this design can automatically separate the catheter body 4 from the transducer mounting cylinder 3, making it easy to replace the transducer mounting cylinder 3. The operation is relatively simple.

[0037] The insert 20 is installed on the left side surface of the mounting ring 1. The insert 20 and the socket 17 are mutually adapted to each other. The insert 20 can be stably inserted into the socket 17, thereby ensuring the connection stability between the mounting ring 16 and the mounting ring 1.

[0038] Working Principle: During installation, the adapter ring 6 and transducer body 7 are first installed into the mounting groove 5. Then, the iron ring 10 is installed into the sealing groove 8. At this time, the magnetic ring 9 and the iron ring 10 are magnetically attracted to each other, and the overall connection is relatively stable. At the same time, the connecting ring 11 is fixedly connected to the balloon body 12, so that the balloon body 12 can seal the entire mounting groove 5. After the connecting ring 11 is installed into the sealing groove 8, the air pump pipe 14 and the mounting hole 13 are mutually adapted. Then, the air pump pipe 14 can automatically expel the air from the connecting ring 11 and the balloon body 12, so that the balloon body 12 will... The transducer mounting cylinder 3 fits snugly against the outer surface of the transducer body 7, resulting in a good overall seal. This simplifies installation and ensures a good seal. The transducer mounting cylinder 3 is then installed into the mounting groove 5, completing the installation between the conduit body 4 and the transducer mounting cylinder 3. The right side of the mounting ring 16 then abuts against the left side of the mounting ring 1, and the insertion post 20 is inserted into the insertion hole 17. Once the mounting ring 16 and the mounting ring 1 are firmly in contact, the stabilizing post 23 is inserted into the stabilizing groove 19. The left surface of the stabilizing post 23 then abuts against the right surface of the spring body 21, thus... The spring body 21 is compressed, and then the right side surface of the positioning block 18 abuts against the left side surface of the connecting block 22. After the positioning block 18 and the connecting block 22 are connected, the abutment plate 26 is pushed downward inside the connecting plate 25, so that the right side surface of the abutment plate 26 fits against the left side surface of the positioning block 18. Therefore, the position of the positioning block 18 and the connecting block 22 after installation can be stabilized, and the overall stability effect is good. After the operation is completed, by holding the stabilizing block 27 and pulling the abutment plate 26 upward, the abutment plate 26 will release the limiting effect of the positioning block 18 and the connecting block 22. In addition to the limiting effect, the elastic design of the spring body 21 can automatically push the positioning block 18 to the left. When the positioning block 18 moves to the left, the mounting ring 16 and the conduit body 4 will also be pushed to the left, thus automatically separating the conduit body 4 from the transducer mounting cylinder 3, avoiding the previous manual separation. At the same time, the mounting ring 16 can be unscrewed from the outer surface of the conduit body 4 for recycling. Then, the mounting ring 16 is connected to the guide ring 28 through the telescopic cylinder 29. The design of the guide ring 28 can limit the position of the conduit body 4. The above is the working principle of the present invention.
