Description

Technical Field

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

[0002] After surgical treatment of renal cancer patients, nephrectomy can cause the intestinal tube in the abdominal cavity to move to the renal fossa. The possibility of intestinal perforation complications will affect the implementation of the patient's subsequent radiotherapy. Clinically, a packing water bag with continuous compression and hemostasis can be placed in the drainage port to push the intestinal tube in the abdominal cavity to ensure the 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 adjusted directly by the drainage tube located outside the body through the knob, 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 rotational friction of the drainage tube. In view of this, the present application proposes a renal fossa radiotherapy auxiliary water bag packing device. Summary of the invention

[0008] Optionally, the helical 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 bag packing device, which has the following beneficial effects:

[0011] 1. The present invention provides a rotation adjustment mechanism between the first tube section provided with the capsule and the second tube section. When water is injected into the second tube section by a syringe, the second movable tube is pushed forward along the axial direction of the fixed tube. The shaft rod on the outer wall of the second movable tube pushes the first movable tube to deflect, thereby adjusting the angle of the capsule. The capsule angle can be adjusted while the first tube body is fixed, which is simple to operate and highly safe.

[0012] 2. The present invention provides a radially divergent shunt pipe on the outer wall of the capsule, and the upper section of the shunt pipe extends to the upper half of the capsule. After the capsule 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 part of the front end of the capsule, thereby preventing the cleaning liquid from directly flushing the organs, and having high safety.

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

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work 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 balloon bodies 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, 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 arranged in the fixed tube 31, and 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 arranged on the outer wall surface of the second movable tube 33, and 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, and the sliding movement of the second movable tube 33 in the fixed tube 31 can realize that the shaft rod 331 pushes the groove wall of the spiral groove 321 and drives the first movable tube 32 to deflect relative to the fixed tube 31. Since the capsule 12 can reach the target angle by a deflection of 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 be deflected more to compensate for the torsional deformation caused by the flexibility.

[0018] On the basis of the above embodiment, the upper end of the second movable tube 33 is provided with a first annular plugging plate 332, the connection between the first movable tube 32 and the first pipe section 1 is provided with a second annular plugging plate 322, and a reset spring 34 is provided between the first annular plugging plate 332 and the second annular plugging plate 322. After the external force on the second movable tube 33 is removed, the second movable tube 33 can be reset under the action of the reset spring 34, so that the external force can be applied to the second movable tube 33 to control the rotation of the first movable tube 32. The inner circle of the first annular plugging plate 332 is fixedly provided with an inner tube 333, and the second pipe section 2 is provided with a concentrically distributed third pipe section 4. A rotation adjustment chamber 23 is formed in the second pipe section 2 and outside the third pipe section 4. Therefore, when water is injected into the rotation adjustment chamber 23, the first annular plugging plate 332 can be pushed forward by water, thereby realizing the linear forward movement of the second movable tube 33. Further, 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 is arranged to penetrate the pipe wall of the second pipe section 2. Since the upper end of the inner tube 333 is connected to the upper part of the inner cavity of the first movable tube 32 and the first tube segment 1, the third tube segment 4 is also connected to the first tube segment 1, and a drainage output cavity 41 is formed in the third tube segment 4. The output end of the third tube segment 4 is used to connect the drainage bag. The third tube segment 4 passes through the second tube segment 2, so that the third tube segment 4 and the second tube segment 2 can be connected to the drainage bag and the syringe respectively without affecting each other.

[0019] On the basis of the above embodiment, a first guide channel 11 is provided in the outer wall of the first pipe section 1, a second guide channel 21 is provided in the outer wall of the second pipe section 2, the first guide channel 11 is connected to two capsules 12 (or is connected to one of the capsules 12 and the two capsules 12 are connected), the second guide channel 21 is connected to the capsule input section 211, and a stretchable and deformable first connecting section 5 is connected between the first guide channel 11 and the second guide channel 21. By connecting a syringe through the first connecting section 5, water filling can be achieved in the capsule 12, and the water in the capsule 12 can also be extracted by the syringe after the radiotherapy is completed, so as to remove the first pipe section 1 later.

[0020] On the basis of the above-mentioned embodiment, the outer wall surface of the capsule 12 is provided with a plurality of shunt tubes 121 which diverge in a radial shape from bottom to top, the upper section of the shunt tube 121 is expanded and extends to the upper half of the capsule 12, and a third guide channel 22 is provided in the outer wall of the second tube section 2, and a second stretchable and deformable connecting section 6 is connected between the third guide channel 22 and the shunt tube 121, and 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 balloon 12 is filled, its front end will be deformed into a large head or a flat head shape due to pressure. The water ejected from the shunt tube 121 will easily flow to the deformed front end of the balloon 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.
