Description

Technical Field

[0001] This invention relates to the field of clinical urological technology, specifically to a prostate dilation device for clinical urological procedures. Background Technology

[0002] A search revealed Chinese Patent Publication No. CN222566589U, which discloses a clinical prostate dilation device for urology. The device includes an external catheter, a guide rod disposed inside the external catheter, a groove at one end of the external catheter, and a dilation assembly movably connected to the guide rod. This invention, by incorporating the dilation assembly, not only dilates the prostate but also retracts the balloon into the external catheter during insertion and withdrawal, preventing urethral damage during entry and exit. Furthermore, it allows for precise repositioning of the balloon during use. The existing technical solutions described above have the following drawbacks: during surgery, the patient's legs must remain open without adequate support, making prolonged maintenance extremely difficult and significantly increasing the surgical challenge. Additionally, the lack of lubrication after prolonged insertion into the urethra can lead to urethral injury upon withdrawal. Therefore, this clinical prostate dilation device for urology is proposed to address these issues. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a prostate dilation device for clinical use in urology, which has the following beneficial effects:

[0018] 1. This urological clinical prostate dilation device, through the setting of a support mechanism, uses a bracket to support the patient's legs. A servo motor drives a bidirectional threaded rod to rotate, causing the threaded slider to move the bracket in opposite directions, adjusting the bracket spacing to fix the patient's legs. An electric telescopic rod pushes the moving plate up and down, which, together with the vertical plate, slides in the groove to ensure that the bracket height allows for comfortable use by the patient, thus achieving the purpose of having a support structure.

[0019] 2. This urological clinical prostate dilation device, through its adjustment, dilation, and lubrication mechanisms, utilizes a servo motor to drive a threaded rod to rotate, causing a threaded block to move up and down along a vertical rod. Simultaneously, a rectangular frame linked to a slider allows for synchronous lifting and lowering of the moving frame, enabling adjustment of the device's height for easy operation by medical staff. An electric push rod pushes the pressure block downwards, working in conjunction with the base pad to fix the outer tube, ensuring precise axial positioning of the dilation mechanism. The balloon inflates through the air inlet and connecting air tube. The outer handle allows doctors to manually fine-tune the dilation direction. Lubricant is injected into the internal tube through the oil inlet tube, pushing the piston ring to move. Lubricant seeps out through the oil outlet of the rubber block, lubricating the urethra and the device's contact surface. A telescopic spring linked to the ring automatically replenishes the lubricant. When lubrication is needed, an operation switch commands the control system to open the electric valve, allowing lubricant to flow into the internal tube. When lubrication is not needed, the electric valve automatically closes to prevent leakage. The electric valve can also precisely control the lubricant flow rate to prevent excessive leakage.

[0036] An annular pad is provided on the left side of the ring 56. A circular hole matching the push rod 54 is opened on the left side of the inner wall of the internal tube 51. There are three sets of rubber blocks 53, and the number of each set shall not be less than five. The rubber blocks 53 in each set are distributed in a ring at equal distances. Multiple sets of oil outlet holes ensure uniform lubrication. The rubber blocks are elastic to adapt to different pressures. One end of the rubber pad 53 extends to the inner side of the internal tube 51. An electric valve is provided on the wall of the oil inlet pipe 59 to prevent lubricant leakage due to misoperation during the operation.

[0037] The support mechanism 6 includes rectangular slots 601. Two rectangular slots 601 are formed on the top of the base plate 1. A servo motor 602 is fixedly installed on the front inner wall of the front rectangular slot 601. A bidirectional threaded rod 603 is fixedly installed at the output shaft of the servo motor 602, extending through and into the inner side of the rear rectangular slot 601 and rotatably connected to its inner wall. Two threaded sliders 604 are threadedly connected to the outer side of the bidirectional threaded rod 603. The top of the threaded sliders 604 is fixedly installed with a sliding connection to the top of the base plate 1. The tray 605 has a base box 606 fixedly installed on its top. The base box 606 has sliding grooves 607 on both its front and rear sides. An electric telescopic rod 608 is fixedly installed on the inner bottom wall of the base box 606. A movable plate 609 is fixedly installed at the output end of the electric telescopic rod 608, which is slidably connected to the inner wall of the base box 606 and extends to its top. A bracket 610 is fixedly installed on the top of the movable plate 609. A vertical plate 611 is fixedly installed at the bottom of the bracket 610, which extends to the inside of the sliding groove 607 and is slidably connected to it.

[0038] The top of the bracket 610 is provided with a soft pad, the top of the base box 606 is provided with a rectangular groove that matches the movable plate 609, the outer side of the bidirectional threaded rod 603 is provided with two threads of equal length and opposite direction, and the two brackets 610 are symmetrically distributed front and back.

[0039] During use, the patient lies supine. The base plate 1 is fixed to the edge of the operating table via the connector. The spacing and height of the brackets 610 are adjusted according to the patient's leg length so that the perineum is positioned between the two brackets. The soft pad reduces pressure. The outer tube 401 is placed between the base pad 307 and the pressure block 308 of the adjustment mechanism 3. The electric push rod 309 is activated to fix the outer tube, which is then inserted into the dilation mechanism 4 through the urethra. During insertion, the balloon 404 and the round tube 405 are retracted into the outer tube 401. The direction is finely adjusted using the outer handle 410 so that the abutment 406 is aligned with the prostate compression site, and the dilation mechanism 4 is opened simultaneously. The lubricant automatically leaks out through the oil inlet valve 59. The lubricant is discharged more quickly by manually pushing the ring 56. When the device reaches the prostate, the balloon 404 is inflated through the air inlet pipe 407 and maintained for 10 minutes to fully expand the prostate tissue. Then the air is gradually deflated. When the dilation mechanism 4 needs to be removed after the operation, the lubrication mechanism 5 needs to be opened again. After complete removal, the lubrication mechanism 5 valve is closed, residual lubricant is cleaned, the pressure block 308 of the adjustment mechanism 3 is loosened, the outer tube 401 is removed, the support mechanism 6 is adjusted to restore the initial state, and the patient is assisted to leave the operating table.

[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0041] In summary, this urological clinical prostate dilation device, through the setting of support mechanism 6, supports the patient's legs with bracket 610. Servo motor 602 drives bidirectional threaded rod 603 to rotate, causing threaded slider 604 to move support plate 605 in opposite directions, adjusting the spacing of bracket 610 to fix the patient's legs. Electric telescopic rod 608 pushes moving plate 609 up and down, cooperating with vertical plate 611 to slide in groove 607, ensuring that the height of bracket 610 is comfortable for the patient to use, thus achieving the purpose of having a support structure. Through adjustment mechanism 3, dilation mechanism 4 and lubrication mechanism 5, servo motor 301 drives threaded rod 302 to rotate, causing threaded block 304 to move up and down along vertical rod 303. At the same time, through rectangular frame 306 linked slider 310, the moving frame 305 is raised and lowered synchronously, and the height of dilation device can be adjusted as needed to facilitate operation by medical staff. Electric push rod 309 pushes pressure block 308 down, cooperating with base pad 307 to fix outer tube 401, ensuring accurate axial positioning of dilation mechanism. The device 404 expands through the air inlet pipe 407 and connecting air pipe 408. The outer handle 410 allows the doctor to manually fine-tune the expansion direction. The oil inlet pipe 59 injects lubricant into the internal tube 51, pushing the piston ring 55 to move. The lubricant seeps out through the oil outlet hole 53 of the rubber block 52, lubricating the contact surface between the urethra and the device. The telescopic spring 58, in conjunction with the ring 56, enables automatic lubricant replenishment. When lubrication is needed, an operation switch sends a command, and the control system controls the electric valve to open, allowing lubricating oil to flow into the internal tube 51. When lubrication is not needed, the electric valve automatically closes to prevent lubricating oil leakage. At the same time, the electric valve can also precisely control the flow rate of lubricating oil as needed to prevent excessive lubricating oil from causing leakage. This solves the problem that during surgery, the patient's legs must always be in an open position without a corresponding support structure, making it extremely difficult to maintain for a long time and greatly increasing the difficulty of the surgery. Furthermore, the lack of a lubrication structure leads to insufficient lubrication inside the urethra after prolonged insertion, which can cause urethral damage when the device is withdrawn.
