[0036] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a resection and drainage device for urology, comprising: a base 1; a mounting plate 6 disposed on top of the base 1; a mounting frame 11 fixedly connected to the outer right side of the mounting plate 6; a collection bucket 10 disposed in the middle of the mounting frame 11; a drainage tube 12 and a drainage head 13, the drainage tube 12 being installed on the top right side of the collection bucket 10 and the drainage head 13 being installed on the top of the drainage tube 12; a collar 14 sleeved on the outside of the drainage tube 12; a first binding strap 15 and a second binding strap 18, the first binding strap 15 being fixedly connected to the outer right side of the collar 14 and the second binding strap 18 being fixedly connected to the outer left side of the collar 14; a fixing ring 16 and an insert block 17, the fixing ring 16 being fixedly connected to the binding strap. At the top of the first strap 15, the insert 17 is rotatably connected to the inside of the fixing ring 16; and the fixing component is used to fix the collection buckets 10 of different sizes. The collection buckets 10 facilitate the collection of the drained liquid. The inner sides of the second strap 18 are provided with locking holes 19. The insert 17 is inserted into any locking hole 19 to facilitate the fixing of the first strap 15 and the second strap 18. The inner sides of the first strap 15 and the second strap 18 are provided with ventilation holes 20. The ventilation holes 20 avoid local stuffiness and dampness caused by long-term wear. The outer sides of the base 1 are fixedly connected with mounting rods 2. The bottom of the multiple mounting rods 2 is fixedly connected with mounting blocks 21. The bottom of the multiple mounting blocks 21 is equipped with rollers 3. The rollers 3 facilitate the movement of the draining device.
[0037] Specifically, when using this drainage device, firstly, the drainage head 13 needs to be inserted into the drainage site on the patient's body surface. Then, place the first bandage 15 and the second bandage 18 on the left and right sides of the patient's thigh, respectively, so that the two bandages fully cover the thigh. Next, rotate the insert block 17 to remove it from its original position, thereby releasing its limiting effect on the fixing ring 16 and making the fixing ring 16 movable. Next, pass the second bandage 18 through the inner cavity of the fixing ring 16 from the outside, allowing the second bandage 18 to be tightened along the inside of the fixing ring 16. By pulling the second bandage 18, it is tightly fitted with the first bandage 15, thus firmly fixing the drainage tube 12 to the surface of the thigh. Then, remove the bandages... Align the pre-set locking holes 19 on the second strap 18 with the insertion block 17. After alignment, insert the insertion block 17 into the corresponding locking holes 19 to complete the fixation, thereby completing the fixation operation of the drainage tube 12. To avoid discomfort such as stuffiness and dampness in the local area due to prolonged wear, multiple ventilation holes 20 are respectively provided on the inner surface of the first strap 15 and the second strap 18. The ventilation holes 20 can enhance air circulation, improve the dryness of the wearing area, and improve the patient's comfort during use. This drainage device can prevent the drainage tube 12 from shifting or falling off during changes in the patient's body position, ensure smooth urine drainage, help the postoperative recovery process proceed smoothly, and improve the patient's comfort.
[0038] Reference Figure 2 and Figure 6 The fixing component includes lead screws 23, which are threaded to both sides of the inside of the mounting bracket 11. Handwheels 24 are fixedly connected to the top of both lead screws 23 to facilitate operation. Arc plates 25 are rotatably connected to the bottom of both lead screws 23 to facilitate fixing the collection bucket 10. Both arc plates 25 are made of rubber to increase friction, prevent slippage and cushioning, and avoid damage to the surface of the collection bucket 10 when clamping.
[0039] Specifically, with collection buckets 10 of different sizes fixed, the operator simultaneously rotates two handwheels 24. The rotation of the handwheels 24 will drive the two lead screws 23 connected to them to rotate simultaneously. As the two lead screws 23 rotate, the two arc-shaped plates 25 connected to the bottom at their lower ends begin to move relative to each other. The arc-shaped plates 25 have a curved surface structure, which can better fit the surface contour of collection buckets 10 of different diameters, thereby improving the overall fixing effect. By continuously rotating the handwheels 24, the two arc-shaped plates 25 gradually move closer to the collection buckets 10, and finally form a stable clamping state at the side wall of the collection buckets 10. During this process, the relative movement of the arc-shaped plates 25 not only achieves effective coverage of the collection buckets 10 placed on the placement plate 22, but also can automatically adjust according to the actual size of the collection buckets 10. After the arc-shaped plates 25 are completely attached to and fixed to the collection buckets 10, they prevent movement or tilting, which facilitates the drainage and collection of urine.
[0040] Reference Figure 1 , Figure 2 and Figure 3 A bracket 4 is fixedly connected to the top of the base 1, and an electric push rod 5 is fixedly connected to the top of the bracket 4. The output end of the electric push rod 5 is fixedly connected to the bottom of the mounting plate 6. When adjusting the height of the device, the electric push rod 5 is activated to move the mounting plate 6, which is fixed to the output end, upward. The movement of the mounting plate 6 moves the drainage structure set at the top upward in sync. A bracket 7 is fixedly connected to the upper left side of the mounting plate 6. An air bladder 8 is set inside the bracket 7. A connecting pipe 9 is fixedly connected inside the air bladder 8. The top of the connecting pipe 9 is installed inside the left side of the collection bucket 10. During auxiliary drainage, the air bladder 8 is compressed to generate a certain air pressure or negative pressure effect inside the air bladder 8. Then, with the cooperation of the connecting pipe 9 and the drainage pipe 12, the auxiliary drainage operation is achieved. A placement plate 22 is fixedly connected to the bottom of the mounting frame 11. The collection bucket 10 is set on the top of the placement plate 22. The placement plate 22 facilitates the placement of the collection bucket 10.
[0041] Working principle: In use, insert the drainage head 13 into the drainage area. Then, place the first bandage 15 and the second bandage 18 on both sides of the thigh, covering the thigh with the bandages 15 and 18. Then, rotate the insert block 17 to release the restriction of the fixing ring 16. Then, pass the second bandage 18 through the inside of the fixing ring 16. Then, pull the second bandage 18 to fix the drainage tube 12 to the thigh through the first bandage 15 and the second bandage 18. Finally, connect the locking hole 19 inside the second bandage 18 to the... Align the insert 17, then insert the insert 17 into the corresponding locking hole 19 to fix the drainage tube 12. By opening ventilation holes 20 on both sides of the inside of the first strap 15 and the second strap 18, problems such as local stuffiness and dampness caused by prolonged wearing are avoided, thereby reducing skin discomfort. When using this drainage device, it is easy to fix the drainage tube 12, and prevent the drainage tube 12 from shifting or falling off when the patient changes position, ensuring smooth urine drainage and thus speeding up postoperative recovery.
[0042] When fixing collection buckets 10 of different sizes, firstly, place the collection bucket 10 on the upper part of the placement plate 22 fixed at the bottom of the mounting frame 11. Then, simultaneously, turn the two handwheels 24 to rotate the two lead screws 23. The rotation of the two lead screws 23 causes the two arc-shaped plates 25 connected at the bottom to move relative to each other. Through the relative movement of the two arc-shaped plates 25, the collection bucket 10 placed on the upper part of the placement plate 22 is fixed. This makes it possible to fix collection buckets 10 of different sizes in this drainage device, ensure the stability of the collection bucket 10, prevent movement or tilting, and facilitate the drainage and collection of urine.
