Description

Technical Field

[0001] This invention relates to an expansion device, and more particularly to an adjustable prostate expansion device for urological clinical use, belonging to the field of medical device technology. Background Technology

[0002] The prostate is the largest accessory gland in the male reproductive system. It produces prostatic fluid and participates in reproductive metabolism, making it a very important gland. Prostate diseases can cause significant suffering for patients. Prostatitis can lead to symptoms such as frequent urination, urgency, incomplete urination, and burning pain during urination. Men over 55 years of age often experience varying degrees of benign prostatic hyperplasia (BPH), which becomes a major concern for older men. In the treatment of prostate problems, prostate dilation devices can help dilate the urethra, promptly detect any urethral strictures or confirm the degree and location of any strictures, and also detect any stones in the urethra and bladder. Depending on the width of the male urethra, different sizes of prostate dilation devices are usually used, and each adjustment should only increase by 1 to 3 sizes; otherwise, it can easily cause urethral injury and bleeding.

[0003] The existing prostate dilation devices in urology have the following shortcomings: (1) When changing to a different size prostate dilation device, the prostate dilation device needs to be removed and then a suitable size prostate dilation device needs to be inserted into the urethra. Repeated removal and insertion of the prostate dilation device will cause pain to the patient and is prone to urethral injury; (2) Lubricant needs to be evenly applied to the surface of the prostate dilator before use. As the prostate dilator enters the urethra deeper, the lubricant at the tip of the prostate dilator will be insufficient, causing discomfort to the patient and increasing the risk of urethral injury.

[0004] To address the above shortcomings, developing an adjustable prostate dilation device for urological clinical use that allows for easy adjustment of the device's size based on the patient's urine volume and provides uniform lubrication of the device's surface during use is a pressing issue that needs to be addressed.

[0014] Preferably, the first slide is connected to the inner wall of the side plate via a connecting rod. The top of the moving block is provided with a set of fixed blocks, and the bottom of the fixed blocks is connected with guide posts. The first slide has guide holes that are compatible with the guide posts.

Detailed Implementation

[0030] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0031] like Figures 1-11As shown, the adjustable prostate dilation device for urological clinical use provided in this embodiment includes a first fixing plate 6, multiple side fixing plates 8 installed at the bottom of the first fixing plate 6, and a knob 4 installed at the top of the first fixing plate 6. An elastic baffle 7 is provided between every two side fixing plates 8. The bottom of the elastic baffle 7 and the side fixing plates 8 are connected to a bottom sealing block 13 through a second fixing plate 12. An elastic arc plate 25 is provided on the inner side of the elastic baffle 7. A lead screw 45 is connected to the bottom of the knob 4 through a mounting rod 16. Multiple moving blocks 27 are provided on the lead screw 45. Multiple first electric telescopic rods 35 are connected to the outer side of the moving blocks 27. A first sliding groove 30 is provided on the outer side of the first electric telescopic rod 35. The output end of the first electric telescopic rod 35 is connected to a heat insulation plate 23 through a slider 31 located inside the first sliding groove 30. An expansion umbrella shell 46 is installed on the outer side of the heat insulation plate 23, which is closely attached to the inner wall of the elastic arc plate 25. By using the elastic baffle 7 and the elastic arc plate 25, lubricant can be placed in the cavity formed between the elastic baffle 7 and the elastic arc plate 25. After evenly applying lubricant to the outer side of the elastic baffle 7 and the side fixing plate 8 and inserting it into the urethra, the elastic baffle 7 is slowly pulled out while the knob 4 is turned to squeeze out the lubricant placed between the elastic baffle 7 and the elastic arc plate 25. This effectively improves the problem of the lubricant at the tip decreasing as the insertion depth increases during the insertion of the whole device into the urethra, which causes discomfort to the patient. After the whole device is fully inserted into the urethra, when the power of the first electric telescopic rod 35 is turned on, it can push the dilation umbrella shell 46 to slowly expand outward, thereby adjusting the size of the whole device to a size that is compatible with the size of the patient's urethra, and then slowly expanding. This avoids the pain caused to the patient by repeatedly trying different sizes of prostate dilation devices and effectively reduces the possibility of urethral injury.

[0032] In this embodiment, as Figures 2-5 and Figure 10As shown, the mounting rod 16 passes through the knob 4. Both the mounting rod 16 and the lead screw 45 are hollow rods. Injection tubes 17 are provided on the inner sides of the mounting rod 16, the second fixing plate 12, the bottom sealing block 13, and the lead screw 45. The two ends of the injection tubes 17 are connected to an injection head 5 located at the top of the knob 4 and a drug-dispensing ball 14 located at the bottom of the bottom sealing block 13, respectively. Multiple drug outlet holes 15 are provided on the drug-dispensing ball 14. A set of symmetrically distributed grip plates 1 are provided on the outer side of the knob 4. The top ends of two grip plates 1 are connected to each other through a top plate 2. An operation panel 3 is installed on the top of the top plate 2. Multiple water injection pipes 10 are provided on the outer side of the grip plates 1, all located inside the top of the elastic baffle 7. A sealing cap 11 is installed on the top of the water injection pipe 10. A pull ring 9 is provided on the top of the elastic baffle 7. By making both the mounting rod 16 and the lead screw 45 hollow, the injection tube 17 can be inserted inside the mounting rod 16 and the lead screw 45. The injection tube 17 then passes through the interior of the entire device and connects to the drug-dispersing ball 14, facilitating the injection of medication from the injection head 5 through the injection tube 17 to the drug-dispersing ball 14. The medication is then evenly distributed at the treatment site through multiple dispensing holes 15, allowing for urethral dilation while simultaneously treating prostate diseases. The grip plate 1 facilitates easy handling of the entire device during insertion into the patient's urethra. The top plate 2 allows for the installation of the operation panel 3, enabling start-up and shutdown of the device. The water injection tube 10 facilitates the injection of lubricant into the cavity formed between the elastic arc plate 25 and the elastic baffle 7. The sealing cap 11 seals the water injection tube 10, and the pull ring 9 allows for easy removal of the elastic baffle 7. The arc-shaped side-sliding protrusion 18 can prevent the patient's urethra from being scratched due to the sharp surface of the elastic baffle 7 during the process of pulling the elastic baffle 7. The second sliding groove 51 can make the side-sliding protrusion 18 slide inside the second sliding groove 51 without falling off, thereby achieving both fixation and sliding of the elastic baffle 7.

[0033] In this embodiment, as Figure 6 , Figure 8 and Figure 9As shown, the elastic baffle 7 has arc-shaped sliding protrusions 18 on both sides, and the side fixing plate 8 has two second sliding grooves 51 that correspond to the sliding protrusions 18. The outer surface of the expansion umbrella shell 46 is arc-shaped, and the inner surface of the expansion umbrella shell 46 has multiple inwardly recessed reinforcing heat dissipation ridges. A sealing gasket 49 is provided between the heat insulation plate 23 and the expansion umbrella shell 46. The heat insulation plate 23 is connected to the expansion umbrella shell 46 by multiple sets of bolts 24. Mounting plates 19 are installed at both ends of the expansion umbrella shell 46, the sealing gasket 49, and the heat insulation plate 23. A second mounting block 21 is installed on the mounting plate 19. A first mounting block 20 is provided on both sides of the second mounting block 21. The bottoms of the second mounting block 21 and the first mounting block 20 are respectively connected to a PT100 type temperature sensor 48 and a heating wire 47, both located between the expansion umbrella shell 46 and the sealing gasket 49. By making the expansion umbrella shell 46 into an arc shape, the contact surface between the expansion umbrella shell 46 and the patient's urethra can be made smooth, avoiding discomfort caused by the sharp edges of the surface. By setting multiple inwardly recessed heat dissipation ridges on the inner surface of the expansion umbrella shell 46, and by setting the thermal conductivity of the expansion umbrella shell 46 to be greater than that of the heat insulation plate 23, heat dissipation of the heat insulation plate 23 can be avoided, while heat exchange between the hot water in the cavity formed between the guide post 29 and the expansion umbrella shell 46 can be enhanced, thereby accelerating the heating speed of the expansion umbrella shell 46, improving the warming effect of the expansion umbrella shell 46, and reducing the cold stimulation of the expansion umbrella shell 46 on the patient's urethra. The sealing gasket 49 can prevent water injected between the heat insulation plate 23 and the expansion umbrella shell 46 from leaking out and causing inconvenience to treatment. The mounting plate 19 enables the sealing of the chamber formed between the expansion umbrella shell 46 and the heat insulation plate 23. The second mounting block 21 and the first mounting block 20 facilitate the installation of the temperature sensor 48 and the heating wire 47. The heating wire 47 facilitates the heating of the water inside the chamber, and the temperature sensor 48 facilitates the measurement of the water temperature inside the chamber.

[0034] In this embodiment, as Figure 1 , Figure 7 and Figure 11As shown, the first slide groove 30 is connected to the inner wall of the side fixing plate 8 via the connecting rod 26. A set of fixing blocks 28 are provided at the top of the moving block 27, and a guide post 29 is connected to the bottom of the fixing block 28. A guide hole adapted to the guide post 29 is provided on the first slide groove 30. A base plate 50 connected to the first slide groove 30 is installed below the moving block 27. A through hole 52 for the threaded rod 45 is provided on the base plate 50. Multiple first grooves 36 for installing the first electric telescopic rod 35 are provided on the moving block 27. A set of symmetrically distributed second electric telescopic rods 39 are installed on the inner side of the first grooves 36. A first connecting block 38 is provided at one end of the first electric telescopic rod 35. The first connecting block 38 is rotatably connected to the moving block 27 via a first rotating shaft 41. Anti-slip sleeves 37 are fitted on both sides of the first connecting block 38. A first limiting hole 40 adapted to the second electric telescopic rod 39 is provided on one side of the first rotating shaft 41. The other end of the first electric telescopic rod 35 is provided with a second connecting block 34. The slider 31 has a second groove 32 that is compatible with the second connecting block 34. Two mounting seats 33 are installed on one side of the second groove 32. A third electric telescopic rod 42 is installed on each of the two mounting seats 33. The two third electric telescopic rods 42 are symmetrically distributed. The second connecting block 34 is rotatably connected to the mounting seat 33 through a second rotating shaft 44. A second limiting hole 43 is provided on one side of the second rotating shaft 44. The connecting rod 26 facilitates the fixing of multiple first sliding grooves 30 to the inner wall of the side plate 8. The fixing block 28 facilitates the installation of guide posts 29 at the bottom of the fixing block 28. The guide hole can guide the moving block 27. The base plate 50 can prevent the moving block 27 from moving out of range and affecting the overall function of the device. By setting the second electric telescopic rod 39, when the center lines of the first electric telescopic rod 35 and the slider 31 are on the same straight line, the second electric telescopic rod 39 can be opened using the operation panel 3 and the telescopic end of the second electric telescopic rod 39 can be inserted into the first limiting hole 40, thereby restricting the rotation of the first connecting block 38 relative to the first groove 36. The anti-slip sleeve 37 can prevent the first connecting block 38 from shifting laterally inside the first groove 36, thereby causing the first electric telescopic rod 35 to tilt and affecting the use of the first electric telescopic rod 35.The second groove 32 facilitates the rotation of the second connecting block 34 within the groove 32. The mounting base 33 facilitates the rotational connection of the second connecting block 34 to the mounting base 33 via the second rotating shaft 44. The third electric telescopic rod 42 allows the extended end to insert into the second limiting hole 43 when the third electric telescopic rod 42 extends, thereby restricting the relative rotation between the second connecting block 34 and the mounting base 33. This ensures that the slider 31 and the first electric telescopic rod 35 keep their center lines on the same straight line, preventing relative rotation between the slider 31 and the first electric telescopic rod 35 due to pressure caused by the extension of the first electric telescopic rod 35, which would affect the expansion effect of the expansion umbrella shell 46.

[0035] In this embodiment, as Figures 1-11 As shown in the figure, the working process of an adjustable prostate dilation device for urological clinical use provided in this embodiment is as follows:

[0036] Step 1: When using, open the sealing cap 11, inject lubricant into the cavity formed between the elastic baffle 7 and the elastic arc plate 25, and close the sealing cap 11 after filling. Disinfect the elastic baffle 7, side fixing plate 8, second fixing plate 12, bottom sealing block 13 and medicine ball 14, and apply lubricant evenly. Then grasp the two grip plates 1 and slowly insert the whole device into the patient's urethra.

[0037] Step 2: During insertion into the urethra, while slowly pulling the pull ring 9 to remove the elastic baffle 7, rotate the knob 4 to rotate the mounting rod 16 and the lead screw 45. This causes the moving block 27 to slowly move towards the base plate 50 on the lead screw 45. The first electric telescopic rod 35 then pushes the slider 31 outwards, causing the expansion umbrella shell 46 to press outwards against the elastic arc plate 25. This forces the lubricant filled between the elastic baffle 7 and the elastic arc plate 25 out through the opening where the elastic baffle 7 is removed, thus strengthening the overall device's resistance during insertion into the urethra. For lubrication, when the first electric telescopic rod 35 and the slider 31 are in the same plane, the bottom surface of the moving block 27 and the top surface of the base plate 50 are in contact with each other, and the outermost end of the expansion umbrella shell 46 is just on the same concentric circle as the outermost end of the side fixing plate 8. By opening the second electric telescopic rod 39 and the third electric telescopic rod 42 through the operation panel 3 and connecting the power, the telescopic ends of the second electric telescopic rod 39 and the third electric telescopic rod 42 are respectively inserted into the interior of the first limiting hole 40 and the second limiting hole 43 to prevent the first electric telescopic rod 35 and the slider 31 from rotating relative to each other.

[0038] Step 3: After the elastic baffle 7 and the side fixing plate 8 penetrate the patient's urethra, the first electric telescopic rod 35 is opened through the operation panel 3 to extend the first electric telescopic rod 35 and then expand outward using multiple expansion umbrella shells 46 to dilate the patient's urethra.

[0039] Step 4: During the urethral dilation process, the treatment solution is injected into the injection tube 17 through the injection cap 5 and then evenly distributed in the urethra and the area to be treated through multiple drug outlet holes 15 on the drug dispersing ball 14.

[0040] Step 5: Water can be injected into the cavity formed between the expansion umbrella shell 46 and the sealing gasket 49 through the water injection pipe 22. The first mounting block 20 is opened through the operation panel 3 to heat the water inside the cavity to a certain extent. The second mounting block 21 detects the water temperature in time to avoid the cold touch of the expansion umbrella shell 46 from irritating the patient's urethra and affecting the treatment.

[0041] In summary, in this embodiment, the adjustable prostate dilation device for urological clinical use, by making both the mounting rod 16 and the lead screw 45 hollow, allows the injection tube 17 to be inserted inside the mounting rod 16 and the lead screw 45. The injection tube 17 then passes through the interior of the entire device and connects to the drug-distributing ball 14, facilitating the injection of medication from the injection head 5 through the injection tube 17 to the drug-distributing ball 14. The medication is then evenly distributed at the treatment site through multiple dispensing holes 15, thus achieving urethral dilation while simultaneously treating the patient's prostate disease. The grip plate 1 facilitates easy handling of the entire device during insertion into the patient's urethra, and the top plate 2 allows for the installation of the operation panel 3, enabling the device to be started and stopped using the operation panel 3. The water injection pipe 10 facilitates the injection of lubricant into the cavity formed between the elastic arc plate 25 and the elastic baffle 7. The sealing cap 11 seals the water injection pipe 10, and the pull ring 9 allows for easy removal of the elastic baffle 7. The arc-shaped side-sliding protrusion 18 prevents urethral abrasions caused by the sharp surface of the elastic baffle 7 during removal. The second sliding groove 51 allows the side-sliding protrusion 18 to slide within the groove without falling off, thus achieving both fixation and sliding of the elastic baffle 7. By making the expansion umbrella shell 46 into an arc shape, the contact surface between the expansion umbrella shell 46 and the patient's urethra can be made smooth, avoiding discomfort caused by the sharp edges of the surface. By setting multiple inwardly recessed heat dissipation ridges on the inner surface of the expansion umbrella shell 46, and by setting the thermal conductivity of the expansion umbrella shell 46 to be greater than that of the heat insulation plate 23, heat dissipation of the heat insulation plate 23 can be avoided, while heat exchange between the hot water in the cavity formed between the guide post 29 and the expansion umbrella shell 46 can be enhanced, thereby accelerating the heating speed of the expansion umbrella shell 46, improving the warming effect of the expansion umbrella shell 46, and reducing the cold stimulation of the expansion umbrella shell 46 on the patient's urethra. The sealing gasket 49 can prevent water injected between the heat insulation plate 23 and the expansion umbrella shell 46 from leaking out and causing inconvenience to treatment. The mounting plate 19 allows for the sealing of the chamber formed between the expansion umbrella shell 46 and the heat insulation plate 23. The second mounting block 21 and the first mounting block 20 facilitate the installation of the temperature sensor 48 and the heating wire 47. The heating wire 47 facilitates the heating of the water inside the chamber, and the temperature sensor 48 facilitates the measurement of the water temperature inside the chamber. The connecting rod 26 facilitates the fixing of multiple first sliding grooves 30 to the inner wall of the side fixing plate 8. The fixing block 28 facilitates the installation of guide posts 29 at its bottom. The guide holes, together with the fixed blocks, guide the moving block 27. The base plate 50 prevents the moving block 27 from moving out of its designated range and affecting the overall functionality of the device.By setting the second electric telescopic rod 39, when the center lines of the first electric telescopic rod 35 and the slider 31 are on the same straight line, the second electric telescopic rod 39 can be opened using the operation panel 3 and the telescopic end of the second electric telescopic rod 39 can be inserted into the first limiting hole 40, thereby restricting the rotation of the first connecting block 38 relative to the first groove 36. The anti-slip sleeve 37 can prevent the first connecting block 38 from shifting laterally inside the first groove 36, thereby causing the first electric telescopic rod 35 to tilt and affecting the use of the first electric telescopic rod 35. The second groove 32 facilitates the rotation of the second connecting block 34 within the groove 32. The mounting base 33 facilitates the rotational connection of the second connecting block 34 to the mounting base 33 via the second rotating shaft 44. The third electric telescopic rod 42 allows the extended end to insert into the second limiting hole 43 when the third electric telescopic rod 42 extends, thereby restricting the relative rotation between the second connecting block 34 and the mounting base 33. This ensures that the slider 31 and the first electric telescopic rod 35 keep their center lines on the same straight line, preventing relative rotation between the slider 31 and the first electric telescopic rod 35 due to pressure caused by the extension of the first electric telescopic rod 35, which would affect the expansion effect of the expansion umbrella shell 46.

[0042] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
