Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a renal fossa radiotherapy auxiliary water balloon packing device. Background Art

[0002] After surgical treatment of renal cancer patients, nephrectomy can cause the intestinal tract in the abdominal cavity to move to the renal fossa. Due to the possibility of intestinal perforation complications, the implementation of subsequent radiotherapy for patients can be affected. Clinically, a water bag with continuous compression and hemostasis can be placed in the drainage port to push the intestinal tract in the abdominal cavity to ensure a clear boundary of the target area during radiotherapy. After the water bag is placed in the renal fossa, its position may be deflected and fail to achieve the ideal water injection and pushing effect. If the angle of the water bag in the body is directly adjusted by turning the knob of the drainage tube outside the body, on the one hand, it is difficult to control the deflection amplitude of the water bag, and on the other hand, it is easy to cause the drainage port to be damaged and infected due to the rotation friction of the drainage tube. In view of this, the present application proposes a water bag packing device for renal fossa radiotherapy. Summary of the Invention

[0003] The object of the present invention is to provide a renal fossa radiotherapy auxiliary water balloon packing device for solving the problems raised in the above background technology.

[0006] Optionally, a first guide channel is provided in the outer wall of the first pipe segment, a second guide channel is provided in the outer wall of the second pipe segment, the first guide channel is connected to the sac, the second guide channel is connected to the sac input segment, and a first stretchable and deformable connecting segment is connected between the first guide channel and the second guide channel.

[0007] Optionally, the outer wall of the capsule is provided with a plurality of diversion tubes that diverge in a radial shape from bottom to top, the upper section of the diversion tube is flared and extends to the upper half of the capsule, and a third guide channel is provided in the outer wall of the second tube section, and a second stretchable and deformable connecting section is connected between the third guide channel and the diversion tube, and the third guide channel is connected to a cleaning liquid input section.

[0008] Optionally, the spiral angle of the spiral groove is greater than 180 degrees.

[0009] Optionally, a rotation adjustment cavity is formed in the second tube segment, and a drainage output cavity is formed in the third tube segment.

[0010] Compared with the prior art, the present invention provides a renal fossa radiotherapy auxiliary water balloon packing device, which has the following beneficial effects:

[0011] 1. The present invention provides a rotation adjustment mechanism between the first tube section, which houses the bladder, and the second tube section. When water is injected into the second tube section using a syringe, the second movable tube is pushed forward along the axial direction of the fixed tube. The shaft on the outer wall of the second movable tube deflects the first movable tube, thereby adjusting the angle of the bladder. This allows the bladder angle to be adjusted while keeping the first tube fixed, resulting in simple operation and high safety.

[0012] 2. The present invention provides a radially diverging shunt pipe on the outer wall of the bladder, with the upper section of the shunt pipe extending to the upper half of the bladder. After the bladder is filled with water and pushed forward to deform, the cleaning liquid injected from the cleaning liquid input section will flow through the shunt pipe to the deformed front end of the bladder, preventing the cleaning liquid from directly flushing the organs, thereby improving safety.

[0013] 3. In the present invention, the output end of the shunt tube is close to the indwelling end of the first tube segment. The cleaning fluid injected into the shunt tube can be quickly drawn out through the indwelling tube and drained out of the body through the third tube segment, avoiding fluid accumulation in the body and facilitating cleaning.

DETAILED DESCRIPTION

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example: See Figure 1 As shown, a renal fossa radiotherapy auxiliary water balloon packing device includes a first tube segment 1 for being inserted into the body and retained in the renal fossa, two sections of water-filled balloons 12 are fixedly provided symmetrically on the upper edge of the outer wall of the first tube segment 1, the upper end of the first tube segment 1 is the retention end, and the lower end of the first tube segment 1 is connected to the second tube segment 2 extending outside the body, and a rotation adjustment mechanism 3 is connected between the second tube segment 2 and the first tube segment 1. Specifically, the rotation adjustment mechanism 3 includes a fixed tube 31 fixedly connected to the upper end of the second pipe section 2, a first movable tube 32 rotatably connected to the upper end of the fixed tube 31, the upper end of the first movable tube 32 is connected to the lower end of the first pipe section 1, and a second movable tube 33 is axially slidably provided in the fixed tube 31. The second movable tube 33 and the fixed tube 31 can be slidably connected by keyway cooperation. The second movable tube 33 extends into the first movable tube 32, and a shaft rod 331 is fixedly provided on the outer wall surface of the second movable tube 33. A spiral groove 321 is provided on the inner wall surface of the first movable tube 32. The spiral angle of the spiral groove 321 is greater than 180 degrees, and the shaft rod 331 is arranged in the spiral groove 321. Through the sliding movement of the second movable tube 33 in the fixed tube 31, the shaft rod 331 can push the groove wall of the spiral groove 321 and drive the first movable tube 32 to deflect relative to the fixed tube 31. Since the capsule 12 can reach the target angle by deflecting less than 180 degrees at any angle, and the first tube segment 1 has a certain flexibility, the lower end of the first tube segment 1 needs to deflect more to compensate for the torsional deformation caused by the flexibility.

[0018] In addition to the above embodiment, a first annular baffle 332 is installed at the upper end of the second movable tube 33. A second annular baffle 322 is installed at the connection between the first movable tube 32 and the first pipe section 1. A return spring 34 is installed between the first and second annular baffles 332 and 322. After the external force on the second movable tube 33 is removed, the second movable tube 33 is reset by the return spring 34, allowing subsequent external force to be applied to the second movable tube 33 to control the rotation of the first movable tube 32. An inner tube 333 is fixedly installed at the inner ring of the first annular baffle 332. A third pipe section 4 is concentrically disposed within the second pipe section 2. A rotation adjustment chamber 23 is formed in the second pipe section 2 and outside the third pipe section 4. When water is injected into the rotation adjustment chamber 23, the water pushes the first annular baffle 332 forward, thereby achieving linear forward movement of the second movable tube 33. Furthermore, the upper end of the third pipe section 4 is fixedly connected to the inner tube 333, and the lower end of the third pipe section 4 extends through the wall of the second pipe section 2. Because the upper end of inner tube 333 communicates with the upper portion of the inner lumen of first movable tube 32 and first tube segment 1, third tube segment 4 is also connected to first tube segment 1. A drainage output lumen 41 is formed in third tube segment 4, and the output end of third tube segment 4 is used to connect to a drainage bag. The provision of third tube segment 4 extending through second tube segment 2 facilitates connection of the third tube segment 4 and the second tube segment 2 to a drainage bag and syringe, respectively, without interfering with each other.

[0019] Based on the above embodiment, a first diversion channel 11 is provided within the outer wall of the first tube segment 1, and a second diversion channel 21 is provided within the outer wall of the second tube segment 2. The first diversion channel 11 communicates with both capsules 12 (or communicates with one of the capsules 12 and communicates between the two capsules 12). The second diversion channel 21 is connected to a capsule input section 211. A stretchable first connecting section 5 is connected between the first diversion channel 11 and the second diversion channel 21. A syringe connected to the first connecting section 5 allows water to be injected into the capsules 12. After radiotherapy is completed, the syringe can also be used to extract the water in the capsules 12 for subsequent removal of the first tube segment 1.

[0020] On the basis of the above embodiment, the outer wall surface of the capsule 12 is provided with a plurality of diverter tubes 121 that diverge in a radial shape from bottom to top. The upper section of the diverter tube 121 is expanded and extends to the upper half of the capsule 12. A third guide channel 22 is provided on the outer wall of the second tube section 2. A stretchable and deformable second connecting section 6 is connected between the third guide channel 22 and the diverter tube 121. The third guide channel 22 is connected to a cleaning liquid input section 221. By connecting the syringe through the cleaning liquid input section 221, water can be injected into the shunt tube 121 for flushing. When the capsule 12 is filled, its front end is compressed and deformed into a large head or a flat head shape. The water ejected from the shunt tube 121 can easily flow to the deformed front end of the capsule 12, thereby preventing the cleaning liquid from directly flushing the organs and improving the safety of cleaning. Since the output end of the shunt tube 121 is close to the retention end of the first tube section 1, the cleaning liquid injected into the shunt tube 121 can be quickly drawn out through the retention tube and drained to the outside of the body through the third tube section 4, thereby avoiding fluid accumulation in the body.
