Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a peritoneal dilation device for urological abdominal surgery. Background Technology

[0002] The balloon dilation method involves inserting a balloon into the retroperitoneal space and inflating it using an inflatable tube and a drainage bag. Currently, hospitals use gloves and drainage bags to fabricate the balloon, or they use domestically produced peritoneal dilators. Using gloves to fabricate the balloon is time-consuming and labor-intensive, and the gloves are prone to tearing during inflation, increasing the risk of foreign body retention. Furthermore, the installation, connection, and disassembly of the balloon and tubing are inconvenient and cannot be performed quickly and easily. Additionally, poor sealing and insecure fixation during balloon-tubing connection can lead to ineffective results. Summary of the Invention

A connecting rod 12 is rotatably connected to the outer surface of the core rod 11. The bottom end of the connecting rod 12 is rotatably connected to the top end of the connecting rod 8. A sliding groove 13 is provided on the right side of the inside of the housing 1. A sliding plate 14 is slidably connected inside the sliding groove 13. A fixing rod 15 is fixed between the sliding plate 14 and the connecting rod 8. Sliding grooves 16 are provided on both the front and rear surfaces of the inside of the housing 1. A sliding plate 17 is slidably connected inside the two sliding grooves 16. Several gear teeth 18 are fixed on the lower left side of the sliding plate 14 and the right side of the sliding plate 17. A gear cylinder 19 is rotatably connected between the sliding plate 17 and the sliding plate 14 inside the housing 1. The outer surface of the gear cylinder 19 meshes with the gear teeth 18. Plate grooves 20 are provided on the inner sides of the two clamping plates 3 and the two clamping plates 6. Plate grooves 20 are provided on both the front and rear surfaces of the plate grooves 20. There is a movable groove 21, and movable buckles 22 are movably connected inside the movable groove 21. The eight movable buckles 22 are divided into two groups, and a clamping plate 23 is fixed between the four movable buckles 22 in each group. An air pipe 26 is connected to the right end of the inflatable ball 2. The right end of the air pipe 26 passes through to the right side of the box 1. A threaded tube 27 is threaded inside the air pipe 26. A one-way valve 28 is fixed to the right end of the threaded tube 27. A hose 29 is connected to the left end of the inflatable ball 2. The hose 29 passes through to the left side of the box 1 and is fixed with a fixing tube 30. Limit strips 31 are symmetrically fixed to the outer surface of the fixing tube 30. A movable cover 32 is slidably connected to the outer surface of the fixing tube 30 and the outer surfaces of the two limit strips 31. A fixing block 33 is fixed to the left side of the outer surface of the fixing tube 30. A ring groove 34 is opened on the outer surface of the fixing block 33. Two mounting slots 35 are formed on the outer surface of the fixed block 33 inside the ring groove 34. An airtight rubber ring 36 is fixed on the outer surface of the fixed block 33 outside the ring groove 34. A tension ring 38 is provided inside the ring groove 34. An expansion airbag 37 is fixed on the left side of the outer surface of the tension ring 38. The left end of the fixed block 33 is located inside the expansion airbag 37. A rubber ring groove 39 is formed on the inner surface of the movable cover 32. A retaining ring 40 is fixed on the inner surface of the movable cover 32 inside the rubber ring groove 39. Threaded cylinders 41 are symmetrically fixed on the outer surface of the movable cover 32. Bolts 42 are threadedly connected inside the threaded cylinders 41. A spring 43 is fixed to the left end of the bolt 42. An installation rod 44 is fixed to the left end of the spring 43. The left end of the installation rod 44 extends into the interior of the movable cover 32 and slides inside the threaded cylinder 41.The inflatable ball 2 is made of rubber and has good elasticity. After being compressed, it can return to its initial state through its own elasticity. When in use, depending on the available space, the rear surface of the box 1 can be placed on the ground or a table with the bottom facing out. The air tube 26 has internal threads and is slidably connected to the box 1.

[0027] Furthermore, the mounting rod 44 is adapted to the mounting groove 35, and the mounting rod 44 can be inserted into the mounting groove 35 to allow the fixed block 33 and the movable cover 32 to be detached and connected.

[0028] Furthermore, the airtight rubber ring 36 is adapted to the rubber ring slot 39, and the airtight rubber ring 36 can be inserted into the rubber ring slot 39 along with the expansion airbag 37 to achieve the effect of increasing airtightness.

[0029] Furthermore, the groove 34 is adapted to the retaining ring 40, which can be inserted into the groove 34 to clamp and fix the port of the expansion airbag 37 inside the groove 34.

[0030] Furthermore, a limiting plate 45 is fixed to the outer surface of the fixed tube 30 on the right side of the limiting strip 31. The left side of the limiting plate 45 is fixedly connected to the right end of the limiting strip 31. The limiting plate 45 can prevent the movable cover 32 from sliding off.

[0031] Furthermore, the fixing block 33 is adapted to the movable cover 32, and the fixing block 33 can be inserted into the movable cover 32 to clamp and fix the expansion airbag 37.

[0032] Furthermore, the expansion airbag 37 is made of latex, which is elastic and biodegradable.

[0033] Furthermore, the fixing plate 5 has a U-shaped structure, which allows the fixing rod 7 and the connecting rod 8 to operate normally inside it.

[0034] Furthermore, the left end of the rotating rod 9 extends through to the left side of the box 1 and is fixed with an operating panel 24. An operating lever 25 is fixed on the upper left side of the operating panel 24. By operating the operating lever 25, the turntable 10 can be rotated, thereby inflating the balloon 2.

[0035] Furthermore, a limiting plate 45 is fixed inside the housing 1 on the left side of the slide plate 14. The right side of the limiting plate 45 is in contact with the left side of the slide plate 14, so that the limiting plate 45 can limit the slide plate 14, allowing it to move only up and down.

[0036] In summary, the workflow of this invention is as follows: During use, medical personnel open the right opening of the elastic band 38 and the expansion airbag 37, wrapping the left half of the fixing block 33 inside and engaging the elastic band 38 into the groove 34. The sliding cover 32 moves to the left, gradually engaging the fixing block 33 with the cover 32. When the mounting rod 44 contacts the outer surface of the fixing block 33, because the mounting rod 44 is inclined, it cannot directly engage with the mounting groove 35. Therefore, under pressure, it gradually retracts, compressing the spring 43 until the fixing block 33 engages with the cover 32. At this point, the spring 43 pushes the mounting rod 44 into the mounting groove 35. Due to its inclined shape, the mounting rod 44 does not disengage from the mounting groove 35. At time 5, the fixed block 33 and the movable cover 32 cannot be disengaged, achieving the effect of clamping and fixing the expansion airbag 37. At the same time, the engagement between the airtight rubber ring 36, the rubber ring groove 39 and the ring groove 34, and the retaining ring 40 increases the airtightness, making the installation of the expansion airbag 37 extremely simple and convenient, requiring only two steps, reducing the labor burden on personnel. When replacing or disassembling, rotate the bolt 42, which drives the spring 43 and the mounting rod 44 to move outward, causing the mounting rod 44 to disengage from the mounting groove 35, thereby releasing the connection between the fixed block 33 and the movable cover 32. When it is necessary to inflate and pressurize the expansion airbag 37, rotate the operating lever 25 to rotate the turntable 10, which in turn drives the eccentric rod 11 to rotate the turntable. When the eccentric rod 11 moves, it drives the connecting rod 8 to move up and down through the connecting rod 12. When the connecting rod 8 moves, the fixed rod 7 and the connecting rod 8 move relative to each other or in opposite directions through the structure of the fixed rod 15, the sliding plate 14, the gear 18, and the gear cylinder 19. This achieves the effect of simultaneously pulling or pushing the two connecting shafts 4 to clamp or release the inflatable ball 2 between the clamping plate 3 and the clamping plate 2. When the distance of the two connecting shafts 4 moving in opposite directions increases and the clamping plates 3 and 2 rotate relative to each other to clamp the inflatable ball 2, the angle between the clamping plates 3 and 2 decreases, causing the fixed-length clamping plate 23 to be compressed through the movable buckle. The displacement of the movable groove 21 causes the clamping plate 23 to move closer to and squeeze the inflatable ball 2. This allows the outer surface of the inflatable ball 2 to be compressed over a larger area, which can better inflate and pressurize the expansion bladder 37. When the two connecting shafts 4 move relative to each other, the clamping plate moves away from the inflatable ball 2 and relaxes it. Due to its elastic material, the inflatable ball 2 rebounds after losing compression and returns to its original shape. After returning to its original shape, external air enters the inflatable ball 2 through the one-way valve 28. By continuously rotating the operating lever 25, repeated inflation can be achieved. When deflation is required, the one-way valve 28 is rotated to separate the threaded tube 27 from the air tube 26, releasing the airtight seal and allowing the gas inside the expansion bladder 37 to leak out.
