Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an intelligent flushing and drainage device for transurethral surgery. Background Technology

[0002] Patients often need bladder irrigation and drainage after urethral surgery. Blood clots in the bladder can easily block the urinary catheter drain hole, which is one of the most common complications during catheter drainage. Blood clots accumulate and become stuck at the drain hole, eventually blocking the flow of urine.

[0003] For example, Chinese Patent Publication No. CN111214274B discloses a urinary catheter for hemorrhagic cystitis, comprising a main tube with a urination lumen, an irrigation lumen, an inflation lumen, and a shaped lumen inside. The urination lumen, irrigation lumen, and shaped lumen all penetrate the main tube. One end of the main tube is fixed with a shaped tube communicating with the shaped lumen. A shaped sheath passes through the shaped sheath, which has a cystoscope port and a guidewire port. A cystoscope tube passes through the cystoscope port, and a guidewire passes through the guidewire port. The front end of the guidewire is connected to multiple auxiliary steel wires, which are curved and connected at their ends. This device uses a cystoscope to locate blood clots in the patient's bladder and uses the auxiliary steel wires to clean and break up the blood clots, effectively clearing the blood clots from the bladder and allowing urine to drain smoothly.

[0004] This application achieves blood clot removal by using the elastic opening and repositioning of the auxiliary steel wire. The cage-like shape of the auxiliary steel wire is relatively fixed, which causes it to generate a large reaction force on the inner wall of the main tube after contraction. This affects both the subsequent opening and use of the auxiliary steel wire and the use of other chambers in the main tube, thus limiting its application.

[0005] Therefore, it is necessary to provide an intelligent flushing and drainage device for transurethral surgery to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent irrigation and drainage device for transurethral surgery to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, an intelligent flushing and drainage device for transurethral surgery is designed, in which the elastic filament can completely conform when contracted and expand in a cage-like manner after removal.

[0008] Based on the above ideas, the present invention provides the following technical solution: an intelligent flushing and drainage device for transurethral surgery, including a urinary catheter, the urinary catheter having a urination chamber and a flushing chamber inside, and a placement chamber having a placement chamber at the center of the urinary catheter. The placement chamber contains a plurality of elastic wires, a support component for supporting the elastic wires, and a control component for driving the support component. The plurality of elastic wires are in a close fit relative to the support component. The control component can first move the plurality of elastic wires out of the placement chamber through the support component, and then the support component can drive the plurality of elastic wires from the close fit state to the bending state based on the support component. At this time, the plurality of elastic wires expand in a cage-like shape.

[0009] As a further embodiment of the present invention: the support assembly includes a guide post slidably installed in the placement cavity and a retaining ring fixedly installed in the placement cavity. The retaining ring is movably engaged with the outer surface of the guide post. A collar driven by a control component is fixedly installed on the outer surface of the guide post. The outer surface of the guide post protrudes outward to form a flange for fixing and placing the elastic wire.

[0010] As a further aspect of the present invention: the flange is disposed on the outer surface of the guide post and near the end, and the diameter of the flange is equal to the diameter of the mounting cavity.

[0011] As a further aspect of the present invention: the control component includes a pusher that is slidably installed in the placement cavity, one end of the pusher is fixedly installed with a ring that is fixedly connected to the elastic wire, the other end of the pusher extends to the outside of the catheter and is driven by an external drive component, and a spring is fixedly installed between the pusher and the ring.

[0012] As a further embodiment of the present invention: the push bar has a groove inside, and the spring is located in the groove and is movably sleeved on the outer surface of the guide post.

[0013] As a further aspect of the present invention: the shape of the retaining ring and the collar is not completely circular, and the push bar is in a movable engaging state with the retaining ring and the collar.

[0014] As a further embodiment of the present invention: the ring includes a first circular sleeve fixedly connected to the push bar and a second circular sleeve rotatably engaged with the first circular sleeve, and the elastic wire is fixedly connected to the second circular sleeve; the guide post includes a second cylinder fixedly connected to the flange and a first cylinder rotatably connected to the second cylinder, the collar is fixedly installed on the outer surface of the first cylinder, and the second circular sleeve is fixedly connected to the second cylinder.

[0015] As a further aspect of the present invention: an adjustment component is provided between the first sleeve and the second cylinder, which allows the second cylinder, the second sleeve, and the elastic wire to rotate synchronously.

[0016] As a further aspect of the present invention: the adjustment component includes a slider fixedly installed inside the first circular sleeve and a spiral groove formed on the outer surface of the second cylinder, wherein the slider is slidably engaged in the spiral groove.

[0017] As a further aspect of the present invention: several elastic wires are bonded together in pairs, and the combination of several elastic wires can form a complete circle.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: through the cooperation between the support component, the control component, and the elastic wire, the support component and the elastic wire can be moved out of the placement cavity first while the elastic wire remains in a close-fitting state. Then, the elastic wire can be moved from the close-fitting state to the bending state based on the support component. At this time, the multiple elastic wires expand in a cage-like shape. By controlling the different moving distances of the control component, the size of the cage-like shape composed of the overall elastic wires can be automatically adjusted. At this time, the expansion and contraction of the elastic wires in a cage-like shape can effectively clear the blocked blood clots.

[0019] The cage-like structure, composed of elastic wires, can automatically adjust its size, thereby improving the removal of blood clots. Furthermore, because the placement cavity is centered on the catheter, the expansion and contraction of the elastic wires in a cage-like manner can simultaneously cut the entire area of ​​the catheter, further enhancing the removal of blood clots.

[0020] Finally, when cleaning is required, several elastic wires expand into a cage-like shape. Subsequently, the elastic wires can be independently and dispersedly attached to the support component. This avoids the size limitations caused by using fixed-size cage-like auxiliary steel wires, and also avoids the overall compression and opening process required for the auxiliary steel wires. This effectively extends the service life of the elastic wires, thereby ensuring a stable cleaning effect on blood clots. Furthermore, the shrinkage of the elastic wires after attachment can effectively reduce the squeezing damage to the placement cavity, which is also conducive to ensuring the reliable use of the urination cavity and the flushing cavity. Therefore, it is more practical. Attached Figure Description

[0033] Example 1:

[0034] Please see Figures 1 to 5 This invention provides an intelligent irrigation and drainage device for transurethral surgery, primarily used to effectively remove blood clots and ensure the stable use of the elastic wire 4. The device includes a catheter 1, with a urination chamber 101, an irrigation chamber 102, and a placement chamber 103 formed axially inside the catheter 1. The urination chamber 101 connects to an external urination tube to drain urine from the bladder, while the irrigation chamber 102 connects to an external irrigation tube to drain the irrigation medium. Simultaneously, when the catheter 1 is inserted into the bladder, a balloon 5 fixed externally to the catheter 1 maintains its position within the bladder. In the above structure, the external urination tube and the external irrigation tube are not shown in the figures; both, along with the balloon 5, are existing mature technologies and will not be described in detail here.

[0035] Furthermore, such as Figure 2As shown, the placement cavity 103 is located at the center of the catheter 1. Inside, several elastic wires 4 are arranged in a circular array. In this embodiment, the number of elastic wires 4 is set to six. The placement cavity 103 also contains a support assembly 2 for supporting the six elastic wires 4. When the support assembly 2 is concealed within the placement cavity 103, the elastic wires 4 are completely attached to the support assembly 2, forming a straight line based on the support assembly 2. The placement cavity 103 also contains a control assembly 3 for driving the support assembly 2. In use, the control assembly 3 can extend from the side of the catheter 1 away from the balloon 5 for medical personnel to operate. When the control assembly 3 is activated, it first moves the support assembly 2 and the elastic wires 4 out of the placement cavity 103. Then, the control assembly 3 continues to activate, causing the elastic wires 4 to change from an attached state to a bent state based on the support assembly 2. At this time, the six elastic wires 4 expand in a cage-like shape.

[0036] Reference Figures 2 to 4 In this embodiment, preferably, the support component 2 includes a guide post 201 slidably installed in the mounting cavity 103 and a retaining ring 202 fixedly installed in the mounting cavity 103. The retaining ring 202 is movably engaged with the outer surface of the guide post 201. When the guide post 201 slides in the mounting cavity 103, it can move along the inner wall of the retaining ring 202. The outer surface of the guide post 201 is also fixedly installed with a collar 203 driven by the control component 3. When the control component 3 drives the collar 203 to move, it can drive the guide post 201 to move synchronously.

[0037] Furthermore, such as Figure 4 As shown, a flange 204 for fixing and placing the elastic wire 4 is formed on the outer surface of the guide post 201 near the end position. The diameter of the flange 204 is equal to the diameter of the placement cavity 103, so that when the guide post 201 is hidden in the placement cavity 103, the flange 204 can close the placement cavity 103.

[0038] Reference Figures 2 to 5 In this embodiment, preferably, the control component 3 includes a pusher 301 slidably mounted within the placement cavity 103. One end of the pusher 301 is fixedly mounted with a ring 302 that can push the elastic wire 4 to move. In this embodiment, the end of the elastic wire 4 away from the flange 204 is fixedly mounted on the pusher 301, thus forming synchronous movement between the two. The other end of the pusher 301 extends to the outside of the catheter 1 and is driven by an external drive (not shown in the figure). Of course, the other end of the pusher 301 extending to the outside can also be manually driven by medical personnel. The drive is also an existing mature technology and will not be described in detail here. A spring 304 is fixedly mounted between the pusher 301 and the ring 203. Under the action of the spring 304, the pusher 301 tends to move away from the elastic wire 4.

[0039] Among them, such as Figure 3 As shown, the push bar 301 has a groove 303 inside. At this time, the spring 304 is movably sleeved on the outer surface of the guide post 201, and the spring 304 is located in the groove 303. The difference between this design and the spring 304 being arranged in parallel outside the guide post 201 is that: on the one hand, the spring 304 has enough space to be placed, and on the other hand, the extension and contraction of the spring 304 is more stable.

[0040] Furthermore, such as Figure 5 As shown, the retaining ring 202 and the collar 203 have the same shape, both being incompletely annular. The pusher 301 is in a movable engagement state with both the retaining ring 202 and the collar 203. The pusher 301 is engaged in the notch of the retaining ring 202 and the collar 203. Since the retaining ring 202 is fixedly installed in the mounting cavity 103, it can limit the pusher 301 and prevent it from rotating in the mounting cavity 103. Because the pusher 301 cannot rotate, the collar 203, which is movablely engaged with the pusher 301, also cannot rotate, thus preventing the collar 203 and the guide post 201 from rotating in the mounting cavity 103.

[0041] When in use, the catheter 1 is inserted into the bladder and fixed by the balloon 5. When there is a blood clot blocking the bladder, the push bar 301 is pushed to move the ring 302 and the spring 304. At this time, the spring 304 drives the guide post 201 to move through the collar 203, so that the push bar 301, the guide post 201 and the ring 302 move synchronously, and the elastic wire 4 can keep in contact with the outer surface of the guide post 201. When the collar 203 abuts against the retaining ring 202, the guide post 201 and the flange 204 can no longer move. At this time, the pusher 301 drives the ring 302 to continue moving. The spring 304 is in a state of gradual compression based on the collar 203. The ring 302 drives the end of the elastic wire 4 away from the flange 204, so that the elastic wire 4 changes from a close state to a bent state, and the six elastic wires 4 expand in a cage shape. During this process, by pushing the ring 302 to move by different distances, the size of the cage formed by the elastic wires 4 can be automatically adjusted. During the expansion and contraction of the elastic wires 4 in a cage shape, the blood clot can be effectively cut.

[0042] In this embodiment, the position of the ring 302 is not specifically limited when the collar 203 abuts against the retaining ring 202. However, it can be understood that as long as the continued movement of the ring 302 can cause the six elastic wires 4 to expand in a cage-like shape, and as long as the elastic wires 4 do not interfere with the placement cavity 103 and the catheter 1 during expansion, it is acceptable. Of course, if... Figure 5 As shown, the width of the ring 302 can be increased accordingly, so that when the six elastic wires 4 expand in a cage-like shape, the ring 302 will not detach from the mounting cavity 103, thus maintaining the relative closure of the mounting cavity 103.

[0043] In summary, through the cooperation of structures such as guide post 201, retaining ring 202, pusher 301, and circular ring 302, the guide post 201 can first be driven to extend from the placement cavity 103, keeping the elastic wire 4 in a straight, fitted state. Then, the elastic wire 4 can be driven to move further based on the guide post 201, changing from a fitted state to a bent state. At this time, the six elastic wires 4 expand in a cage-like shape. By adjusting the circular ring 302 based on the different moving distances of the guide post 201, the size of the cage-like shape composed of the elastic wires 4 can be automatically adjusted. At this time, the expansion and contraction of the elastic wires 4 in a cage-like shape can effectively clear the blocked blood clots.

[0044] The cage-like structure composed of the elastic wires 4 can be automatically adjusted, thereby improving the cleaning effect on blood clots. At the same time, since the placement cavity 103 is based on the catheter 1 and is arranged in the center, the six elastic wires 4 can simultaneously cut the entire area of ​​the catheter 1 when they expand and contract in a cage-like manner, thereby further improving the cleaning effect on blood clots.

[0045] Finally, when cleaning is required, the six elastic wires 4 expand into a cage-like shape. Subsequently, the elastic wires 4 can be independently dispersed and attached to the outer surface of the guide post 201. This avoids the size limitations caused by using fixed-size cage-like auxiliary steel wires, and also avoids the overall compression and opening process required for the auxiliary steel wires. This can effectively extend the service life of the elastic wires 4, thereby ensuring a stable cleaning effect on blood clots. Furthermore, the shrinkage of the elastic wires 4 after attachment can also effectively reduce the squeezing damage to the placement cavity 103, which is also conducive to ensuring the reliable use of the urination cavity 101 and the flushing cavity 102. Therefore, it is more practical.

[0046] Example 2:

[0047] Please see Figures 1 to 8 Based on Embodiment 1, in order to further improve the cleaning effect on blood clots, the ring 302 and guide post 201 are improved: the ring 302 includes a first sleeve 3021 fixedly connected to the pusher 301 and a second sleeve 3022 rotatably engaged with the first sleeve 3021. The end of the elastic wire 4 away from the flange 204 is fixedly connected to the end of the second sleeve 3022 away from the first sleeve 3021. Meanwhile, the guide post 201 includes a second cylinder 2012 fixedly connected to the flange 204 and a first cylinder 2011 rotatably connected to the second cylinder 2012. The collar 203 is fixedly installed on the outer surface of the first cylinder 2011, and the second sleeve 3022 is fixedly connected to the second cylinder 2012.

[0048] The above design allows the second cylinder 2012, flange 204, second sleeve 3022, and six elastic wires 4 to rotate synchronously. Furthermore, in this structure, to accommodate the increased width of the ring 302, the width of the first sleeve 3021 also needs to be increased accordingly.

[0049] Furthermore, such as Figure 6 As shown, an adjustment component 6 is provided between the first sleeve 3021 and the second cylinder 2012. When the collar 203 of the first cylinder 2011 abuts against the retaining ring 202 and no longer moves, the second cylinder 2012 also stops moving. At this time, if the push bar 301 drives the first sleeve 3021 and the second sleeve 3022 to continue moving, the adjustment component 6 can drive the second cylinder 2012, the flange 204, the second sleeve 3022 and the six elastic wires 4 to rotate continuously. During this process, the six elastic wires 4 can expand in a cage-like shape.

[0050] Reference Figures 6 to 8 In this embodiment, preferably, the adjusting component 6 includes a slider 602 fixedly installed inside the first sleeve 3021 and a spiral groove 601 formed on the outer surface of the second cylinder 2012. The slider 602 is slidably engaged in the spiral groove 601. When the push bar 301 drives the first sleeve 3021, the second sleeve 3022, and the slider 602 to move, the push bar 301 drives the first cylinder 2011, the second cylinder 2012, and the spiral groove 601 to move synchronously through the spring 304. At this time, the slider 602 is relatively stationary in the spiral groove 601. When the collar 203 abuts against the retaining ring 202, the first cylinder 2011 and the second cylinder 2012 no longer move. At this time, the slider 602 moves along the spiral groove 601 with the first sleeve 3021, causing the second cylinder 2012, the flange 204, and the second sleeve 3022 to start rotating.

[0051] It should be noted that in this embodiment, the frictional force of the slider 602 along the spiral groove 601 is less than the elastic force of the spring 304 acting on the collar 203. As a result, during the initial pushing process, the push bar 301 can only move the collar 203 and the first cylinder 2011 through the spring 304, and cannot make the first sleeve 3021 drive the slider 602 to slide along the spiral groove 601.

[0052] In use, the structure of retaining ring 202, push bar 301 and flange 204 allows the six elastic wires 4 to expand in a cage shape after being removed from the placement cavity 103, effectively clearing the blocked blood clots. The working process and effect of this part are the same as in Example 1, and will not be repeated here. The difference is that when the push bar 301 moves the first sleeve 3021 and the second sleeve 3022, the spring 304 also moves the collar 203, the first cylinder 2011 and the second cylinder 2012 synchronously. When the collar 203 abuts against the retaining ring 202, the first cylinder 2011 and the second cylinder 2012 stop moving, while the push bar 301 continues to move the first sleeve 3021 and the second sleeve 3022. At this time, the slider 602 moves along the spiral groove 601, causing the second cylinder 2012, the flange 204, the second sleeve 3022 and the elastic wire 4 to start rotating. During this process, the movement of the second sleeve 3022 also causes the six elastic wires 4 to expand in a cage-like shape.

[0053] Compared to Embodiment 1, through the cooperation of the first sleeve 3021, the second cylinder 2012, the slider 602 and the spiral groove 601, the second cylinder 2012 and the second sleeve 3022 can be driven to rotate synchronously during the expansion and contraction of the six elastic wires 4 in a cage-like manner. This allows the six elastic wires 4 to continue rotating, which can further improve the cleaning effect on blood clots and help ensure the reliable use of the urinary catheter 1.

[0054] Example 3:

[0055] Please see Figures 1 to 10 Based on the second embodiment, in order to prevent bladder fluid from entering the placement cavity 103, the number of elastic wires 4 and the position of the spiral groove 601 are improved: at this time, the number of elastic wires 4 is increased to several, the elastic wires 4 are attached in pairs and several elastic wires 4 are combined to form a complete circle, thereby effectively sealing the space between the second circular sleeve 3022 and the flange 204.

[0056] At the same time, such as Figure 10 As shown, the spiral groove 601 of the second cylinder 2012 can be opened on the side of the second sleeve 3022 near the first sleeve 3021, and the slider 602 can be set on the side of the first sleeve 3021 near the retaining ring 202. At this time, the first sleeve 3021 completely covers the spiral groove 601, so that there is no gap in the area on the outer surface of the second cylinder 2012 and between the second sleeve 3022 and the flange 204.

[0057] In use, the six elastic wires 4 can expand in a cage-like shape after being removed from the placement cavity 103 through the structure of retaining ring 202, push bar 301 and flange 204, effectively clearing the blocked blood clots; through the structure of first circular sleeve 3021, slider 602 and spiral groove 601, the six elastic wires 4 can also rotate continuously during the cage-like expansion and contraction process. The working process and effect of this part are the same as in embodiment 2, and will not be repeated here. The difference is that when the collar 203 abuts against the retaining ring 202, the first cylinder 2011 and the second cylinder 2012 no longer move. At this time, the continued movement of the first sleeve 3021 causes the second cylinder 2012 to rotate through the slider 602 and the spiral groove 601, and causes several elastic wires 4 to expand in a cage shape. When the pusher 301 drives the first sleeve 3021 to reset, the several elastic wires 4 contract to form an effective seal on the outer surface of the second cylinder 2012 and in the area between the second sleeve 3022 and the flange 204.

[0058] Compared to Embodiment 2, by adjusting the number of elastic wires 4, several elastic wires 4 can form a complete circle after contraction, effectively sealing the area on the outer surface of the second cylinder 2012 and located between the second sleeve 3022 and the flange 204. This can effectively reduce the amount of liquid remaining on the outer surface of the second cylinder 2012, thereby preventing bladder fluid from entering the placement cavity 103 and ensuring the effective subsequent drainage of the fluid.

[0059] Meanwhile, by adjusting the position of the spiral groove 601, there are no gaps on the outer surface of the second cylinder 2012 and in the area between the second sleeve 3022 and the flange 204. Combined with the adjustment of the number of elastic wires 4, it is ensured that no liquid enters the placement cavity 103, which can reduce the occurrence of accidents such as infection and meet more needs in actual use.
