Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a pressure-adjustable urethral suspension belt. Background Technology

[0002] A search revealed Chinese Patent Publication No. CN217548306U, which discloses a mid-urethral suspension sling. Compared to existing sling structures, this mid-urethral suspension sling is simpler in structure. It comprises a first fixed end, a first connecting end, a sling body, a second connecting end, and a second fixed end. The existing technical solutions described above have the following drawbacks: the suspension sling pressure cannot be adjusted. During suspension surgery, if the sling is too loose, the surgical outcome is poor; if the sling is too tight, the patient experiences difficulty urinating post-surgery, making it difficult to achieve optimal surgical results. Furthermore, the connection and fixation operations are inconvenient, reducing the practicality of the suspension sling. Therefore, this paper proposes a pressure-adjustable urethral suspension sling to solve the aforementioned problems. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a pressure-adjustable urethral suspension belt, which has the following beneficial effects:

[0018] 1. This pressure-adjustable urethral suspension belt, through the setting of a fixing mechanism and a connecting mechanism, has a fixing post that provides basic support for the entire fixing structure. A U-shaped plate is fixed to the top of the cover and extends to the front and rear sides respectively. The clamping plate at the bottom of the U-shaped plate extends into the T-shaped groove inside the limiting frame, realizing a stable connection between the cover and the fixing post, and providing a reliable fixing point for the connecting mechanism. The fixing ropes at the top left and right ends of the flexible belt pass through the fixing cylinders fixedly installed on the left and right sides of the inner wall of the box, and extend to the inner side of the box. The connecting ropes entering the inner side of the box pass around the first wheel, the second wheel and the third wheel in sequence, and finally are fixedly installed on the outside of the fixing post by the collar and located between the two limiting frames. This winding method allows the connecting rope to distribute the force evenly when it is under tension, and by changing the positional relationship of the connecting rope between each wheel, the suspension pressure of the flexible belt on the urethra can be adjusted, achieving the purpose of convenient fixation.

[0019] 2. This pressure-adjustable urethral suspension belt, through the setting of an adjustment mechanism, a limiting mechanism, a first wheel, a second wheel, and a third wheel, has a limiting groove on the inner side of the stabilizing frame that matches the rack, allowing the rack to slide stably inside the stabilizing frame and extend to the outer side. A fixing ring fixed at one end of the rack is sleeved on the outside of the connecting rope and is located between the second and third wheels. A through hole and a protective pad are set on the inner side of the fixing ring to reduce wear on the connecting rope. When the turntable is rotated, the rotating rod drives the gear to rotate, which in turn drives the rack to slide along the stabilizing frame, thereby pulling or releasing the connecting rope to adjust the suspension pressure of the flexible belt. When pressure adjustment is required, the pull ring is pulled, which drives the limiting tooth plate to move to one side against the elastic force of the telescopic spring through the pull rod, so that the limiting tooth plate separates from the gear. At this time, the turntable can be rotated to adjust the pressure. After adjustment, the pull ring is released, the telescopic spring returns to its deformation, and pushes the limiting tooth plate to re-engage with the gear, fixing the adjusted pressure, thus achieving the purpose of pressure adjustment.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-8This invention provides a technical solution: a pressure-adjustable urethral suspension belt, comprising a box body 1 and a flexible belt 3. The flexible belt 3 is located below the box body 1. The box body 1, as the core load-bearing component of the entire urethral suspension belt, provides installation space and protection for the various internal mechanisms, ensuring that each mechanism works normally in a relatively stable and closed environment, preventing external factors from interfering with and damaging the internal structure. A cover 2 is movably installed on the inner top wall of the box body 1, which can be easily opened and closed. When installing, debugging, or maintaining the internal mechanisms, opening the cover 2 facilitates operation. During normal use, closing the cover 2 prevents dust, liquids, etc. from entering the interior of the box body 1, protecting the internal mechanisms. Two first wheels 8 are rotatably connected to the inner bottom wall of the box body 1. The inner bottom wall of the box 1 is rotatably connected to two second wheels 9, and the inner bottom wall of the box 1 is rotatably connected to two third wheels 10. Together with the first wheel 8 and the second wheel 9, they form the winding path of the connecting rope 53, further changing the direction of the connecting rope 53 and the direction of force transmission, so that the tension of the connecting rope 53 on the flexible belt 3 can be evenly distributed, improving the stability and accuracy of pressure adjustment. The inner bottom wall of the box 1 is provided with a fixing mechanism 4, and the top of the flexible belt 3 is provided with a connecting mechanism 5 that extends to the inside of the box 1 and is connected to the fixing mechanism 4. The inner bottom wall of the box 1 is provided with an adjustment mechanism 6 that is connected to the connecting mechanism 5 and extends to the top of the box 1. The inner side of the box 1 is provided with a limiting mechanism 7 that is connected to the adjustment mechanism 6 and extends to the outside of the box 1.

[0031] The fixing mechanism 4 includes a fixing post 41. The fixing post 41 is fixedly installed on the inner bottom wall of the box body 1. Two limiting frames 42 are fixedly installed on the inner bottom wall of the box body 1, located on the front and rear sides of the fixing post 41 respectively. The T-shaped grooves opened on the inner side of the frame 42 are adapted to the card plate 45, providing limiting and guiding functions for the card plate 45, restricting the movement direction of the cover 43, preventing the cover 43 from shifting in the horizontal direction, and ensuring the connection stability of the fixing mechanism 4. The cover 43 is movably installed on the top of the fixing post 41. The cover 43 is used to limit the collar 54 and prevent it from falling off. The top of the cover 43 is fixedly installed with U-shaped plates 44 extending to its front and rear sides respectively. The bottom of the U-shaped plates 44 is fixedly installed with card plates 45 extending to the inner side of the limiting frames 42.

[0032] The connecting mechanism 5 includes a fixing rope 51. The top left and right ends of the flexible belt 3 are fixedly installed with fixing ropes 51, serving as connecting components between the flexible belt 3 and the connecting rope 53. This transfers the tension on the flexible belt 3 to the connecting rope 53, allowing the connecting rope 53 to adjust the pressure on the flexible belt 3 according to the action of the adjusting mechanism 6. The inner walls of the box 1 are fixedly installed with fixing cylinders 52 extending to the outer sides of the box 1. The connecting rope 53 passes through the fixing cylinders 52, which provide guidance and fixation for the connecting rope 53, ensuring a stable connection between the inside and outside of the box 1 and reducing friction between the connecting rope 53 and the wall of the box 1. The top of the fixing rope 51 is fixedly installed with a through-hole fixing cylinder 52. The connecting rope 53 extends to the inside of the box 1. The connecting rope 53 is a key component for transmitting force. By passing around each wheel, it transmits the tension on the flexible belt 3 to the adjustment mechanism 6. The tension on the flexible belt 3 is changed according to the action of the adjustment mechanism 6, thereby adjusting the pressure on the flexible belt 3. One end of the connecting rope 53 located inside the box 1 passes around the first wheel 8, the second wheel 9 and the third wheel 10 in sequence and is fixedly installed with a collar 54. The collar 54 is movably installed on the outside of the fixed post 41 and located between the two limit frames 42. The collar 54 enables the connecting rope 53 to rotate stably around the fixed post 41, while limiting the range of movement of the connecting rope 53 in the horizontal direction, ensuring the stable operation of the connecting rope 53 in the winding system.

[0033] The inner walls of the box 1 are provided with mounting holes on both the left and right sides that are compatible with the fixing cylinder 52. The inner side of the limiting frame 42 is provided with a T-shaped groove that is compatible with the card plate 45. The bottom of the cover 43 is provided with a circular mounting groove that is compatible with the fixing post 41.

[0034] The adjustment mechanism 6 includes a stabilizing frame 61. Two stabilizing frames 61 are fixedly installed on the inner bottom wall of the housing 1. The stabilizing frame 61 provides a sliding track and support for the rack 62, restricting the movement direction of the rack 62 so that the rack 62 can only move in a straight line along the limiting groove of the stabilizing frame 61, ensuring the adjustment accuracy and stability of the adjustment mechanism 6. The rack 62, extending to the outer side of the stabilizing frame 61, is slidably installed on the inner side of the stabilizing frame 61. The rack 62 meshes with a gear 65 and moves in a straight line along the stabilizing frame 61 under the drive of the gear 65. The pressure of the flexible belt 3 is adjusted by pulling or releasing the connecting rope 53 through the fixing ring 63. A fixing ring that fits on the outer side of the connecting rope 53 is fixedly installed at one end of the rack 62. 63. The fixing ring 63 is located between the second wheel 9 and the third wheel 10. The inner bottom wall of the box body 1 is rotatably connected to a rotating rod 64 extending to the inner side of the inner top wall of the box body 1. The rotating rod 64 serves as the rotation shaft of the gear 65, transmitting the rotation of the turntable 66 to the gear 65, driving the gear 65 to rotate, and thus driving the rack 62 to move. The gear 65 that meshes with the rack 62 is fixedly installed on the outer side of the rotating rod 64. The turntable 66 extending to the top of the box body 1 is fixedly installed on the top of the rotating rod 64. The turntable 66 is the external component of the operating adjustment mechanism 6. By inserting a tool into the slot and rotating the turntable 66, the rotating rod 64 and the gear 65 can be driven to rotate, making it convenient for medical staff to adjust the pressure of the urethral suspension belt.

[0035] A limiting groove is provided on one side of the stabilizing frame 61. The size of the limiting groove is adapted to the rack 62. A bearing is fixedly installed at the bottom end of the rotating rod 64. The rotating rod 64 is rotatably connected to the inner bottom wall of the box 1 through the bearing. A circular hole adapted to the rotating rod 64 is provided on the inner top wall of the box 1. A circular groove adapted to the turntable 66 is provided on the top of the box 1. The circular groove is connected to the inner top wall of the circular hole. A strip groove is provided on the top of the turntable 66. A through hole is provided on the inner side of the fixing ring 63. A protective pad is provided on the inner side of the through hole. The second wheel 9 is located on one side between the first wheel 8 and the third wheel 10.

[0036] The limiting mechanism 7 includes fixed plates 71. Two fixed plates 71 are fixedly installed on both the front and rear sides of the inner wall of the box 1. Slide grooves 72 are provided on opposite sides of the left and right fixed plates 71. The slide grooves 72 provide sliding tracks for the limiting toothed plates 73, restricting the movement direction of the limiting toothed plates 73 so that they can only move in a straight line along the slide grooves 72, ensuring that the limiting toothed plates 73 can accurately engage or disengage with the gear 65. A limiting toothed plate 73, engaging with the gear 65, is slidably installed between the inner sides of the left and right slide grooves 72. A mounting cylinder 74, fixedly connected to the inner wall of the box 1, is fixedly installed between the two fixed plates 71. A mounting cylinder 74 is fixedly installed on the inner side of the mounting cylinder 74. The telescopic spring 75, which is fixedly connected to the limiting tooth plate 73, returns to its original shape when the pull ring 78 is released, pushing the limiting tooth plate 73 to re-engage with the gear 65, thereby achieving automatic limiting of the gear 65. The front and rear sides of the box body 1 are provided with slots 76. A pull rod 77 is fixedly installed on one side of the limiting tooth plate 73, passing through the telescopic spring 75 and the mounting cylinder 74 and extending to the inside of the slot 76. A pull ring 78 located inside the slot 76 is fixedly installed at one end of the pull rod 77. The pull ring 78 is an external component for operating the limiting mechanism 7. Medical personnel can operate the limiting tooth plate 73 by pulling the pull ring 78. The protective cover can increase the comfort and anti-slip properties during operation.

[0037] The pull ring 78 is wrapped with a protective sleeve. The side wall of the box 1 has a round hole that matches the pull rod 77. The round hole is connected to the inner wall of the groove 76. The inner wall of the mounting cylinder 74 is open on one side. The fixing plates 71 on the left and right sides are symmetrically distributed.

[0038] Before use, check that all components of the urethral suspension belt are intact and undamaged, ensuring that the fixing mechanism 4, connecting mechanism 5, adjusting mechanism 6, and limiting mechanism 7 are functioning properly. Perform routine disinfection and draping of the surgical area, and prepare other instruments and materials required for the surgery. Place the flexible belt 3 in a suitable position below the urethra, ensuring that it can accurately suspend the urethra. Close the box cover 2 to create a relatively enclosed space inside the box 1, protecting the internal mechanisms from external interference. Pull the pull ring 78, which moves the limiting tooth plate 73 to one side via the pull rod 77, separating the limiting tooth plate 73 from the gear 65 and releasing the restriction on the gear 65. Use a suitable tool to insert into the slot at the top of the turntable 66 to rotate the turntable 66. The rotating rod 64 drives the gear 65 to rotate, driving the rack 62. Slide along the stabilizing frame 61. The fixing ring 63 at one end of the rack 62 pulls or loosens the connecting rope 53. The connecting rope 53 passes around the first wheel 8, the second wheel 9, and the third wheel 10, driving the flexible belt 3 to adjust the suspension pressure on the urethra. Adjust the pressure to a suitable range according to clinical needs. After adjusting to the appropriate pressure, release the pull ring 78. The telescopic spring 75 returns to its deformation and pushes the limiting tooth plate 73 to re-engage with the gear 65, limiting the rotation of the gear 65 and fixing the position of the rack 62 and the connecting rope 53 to ensure the suspension pressure of the flexible belt 3 is stable. Check whether the installation position of the urethral suspension belt is correct, whether the pressure is appropriate, and whether there are any abnormalities. Suture and bandage the surgical incision to complete the surgical operation. Closely observe the patient's recovery after the operation and further adjust the pressure of the suspension belt as needed.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] In summary, this pressure-adjustable urethral suspension belt, through the setting of a fixing mechanism 4 and a connecting mechanism 5, provides basic support for the entire fixing structure 4 with a fixing column 41. A U-shaped plate 44 is fixed to the top of the cover 43 and extends to the front and rear sides respectively. The retaining plate 45 at the bottom of the U-shaped plate 44 extends into the T-shaped groove inside the limiting frame 42, achieving a stable connection between the cover 43 and the fixing column 41, providing a reliable fixing point for the connecting mechanism 5. The fixing ropes 51 and connecting ropes 53 at the top left and right ends of the flexible belt 3 pass through the fixing cylinders 52 fixedly installed on the left and right sides of the inner wall of the box 1, extending into the inner side of the box 1 and entering the box. The connecting rope 53 inside the body 1 passes sequentially around the first wheel 8, the second wheel 9, and the third wheel 10, and is finally fixed to the outside of the fixed post 41 by the collar 54 and located between the two limiting frames 42. This winding method allows the connecting rope 53 to distribute the force evenly when under tension, and by changing the positional relationship of the connecting rope 53 between the wheels, the suspension pressure of the flexible belt 3 on the urethra can be adjusted, achieving the purpose of convenient fixation. By setting the adjustment mechanism 6, the limiting mechanism 7, the first wheel 8, the second wheel 9, and the third wheel 10, the limiting groove opened on the inner side of the stabilizing frame 61 is adapted to the rack 62, so that the rack The rack 62 can slide stably inside the stabilizing frame 61 and extend to the outside. The fixing ring 63 fixed at one end of the rack 62 is sleeved on the outside of the connecting rope 53 and is located between the second wheel 9 and the third wheel 10. The fixing ring 63 has a through hole and a protective pad on its inner side to reduce wear on the connecting rope 53. When the turntable 66 is rotated, the rotating rod 64 drives the gear 65 to rotate, which in turn drives the rack 62 to slide along the stabilizing frame 61, thereby pulling or releasing the connecting rope 53 to adjust the suspension pressure of the flexible belt 3. When the pressure needs to be adjusted, the pull ring 78 is pulled, and the limit tooth plate 73 is driven by the pull rod 77 to overcome the elasticity of the stretching. The elastic force of spring 75 moves to one side, causing the limiting tooth plate 73 to separate from the gear 65. At this time, the turntable 66 can be rotated to adjust the pressure. After adjustment, the pull ring 78 is released, the telescopic spring 75 returns to its deformation, and pushes the limiting tooth plate 73 to re-engage with the gear 65, fixing the adjusted pressure. This achieves the purpose of adjustable pressure and solves the problem that the suspension belt pressure cannot be adjusted. If the suspension belt is too loose during suspension surgery, the surgical effect will be poor. If the suspension belt is too tight, the patient will have difficulty urinating after surgery, making it difficult to achieve the best surgical effect. In addition, the connection and fixation operation is inconvenient, reducing the practicality of the suspension belt.
