DESCRIPTION LU502592

Three-cavity single-sac fistula of ileum

TECHNICAL FIELD

The invention relates to the field of medical and health surgical consumables, in particular to a three-cavity single-sac fistula of ileocecal part.

BACKGROUND

For patients with high risk of anastomotic leakage (such as low rectal cancer, left colon cancer with obstruction, and emergency left colon obstruction) who underwent intestinal anastomosis after surgical resection of the focus, to prevent anastomotic leakage, the mainstream practice at home and abroad is to perform preventive terminal ileostomy during operation, which reduces the pressure in the intestinal cavity of the anastomotic segment by diverting intestinal contents, and the anastomotic stoma heals under the conditions of no perfusion, no load and low bacteria.

Preventive ileostomy has serious disadvantages: firstly, there are risks such as intestinal bleeding, stenosis, necrosis, retraction and prolapse; secondly, the second operation is required to perform enterostomy, which significantly increases the pain of patients and the risk of second operation.

Furthermore, patients' economic burden is aggravated, which consumes a lot of social medical insurance funds. The new type of cecal catheterization is expected to achieve the effect of effectively preventing anastomotic leakage and avoiding secondary operation, significantly reducing the pain and economic pressure of patients, improving the quality of perioperative medical care and reducing the cost of medical insurance.

However, at present, this new type of operation lacks the support of practical and efficient inventions. The traditional method of inserting bacterial latex tube into ileum from the excision of appendix root of cecum, because it can't fully block intestinal fecal fluid, leads to insufficient bypass, poor drainage effect, and easy loosening and slippage, which leads to drainage failure.

And once blocked, there is no design of flushing cavity, and flushing directly from the drainage cavity leads to the reflux of fecal liquid, which is lack of scientific rationality. Therefore, it is urgent to design the three-cavity single-sac fistula of ileocecal part to solve the above problems.

SUMMARY

The purpose and existence of the present invention is to solve the vacancy of required instruments in new surgical techniques, and to propose a three-cavity single-sac fistula of ileocecal part.

In order to achieve the above purpose, the invention adopts the following technical scheme:

a three-cavity single-sac fistula of ileocecal part comprises a tube body, where the outer wall pfj502592 one end of the tube body is provided with a round-headed tube tip, one side of the tube body is externally sleeved with a water sac, and the tube body is internally provided with a drainage cavity, a flushing cavity and a water sac cavity; the outer wall of one end of the tube body is provided with a main branch pipe, an auxiliary branch pipe I and an auxiliary branch pipe II; the inner ends of the auxiliary branch pipe I and the auxiliary branch pipe II are respectively provided with a socket I and a socket II; and a one-way flap is arranged in the socket I, and an anti-reflux flap is arranged inside the socket II.

Furthermore, one end of the drainage cavity is located in the main branch pipe, one end of the main branch pipe is internally provided with a socket III, the drainage cavity is communicated with the socket III, and the other end of the drainage cavity is located inside the round-headed tube tip.

Furthermore, one end of the flushing cavity is located in the round-headed tube tip, and the other end of the flushing cavity is located in the auxiliary branch pipe II, and the auxiliary branch pipe

II is communicated with the socket II.

Furthermore, one end of the water sac cavity is communicated with the inside of the water sac, the other end of the water sac cavity is located inside of the auxiliary branch pipe I, and the water sac cavity is communicated with the inside of the socket I.

Furthermore, the water sac has a ring-shaped structure, and the water sac is not communicated with the inside of the pipe body.

The invention has the beneficial effects that: 1. the auxiliary branch pipe I, the water sac cavity and the water sac are arranged to realize the sealing effect of the water sac cavity; the size of the water sac can be changed by inputting saline into the water sac cavity, and the fecal liquid in the small intestine can be fully blocked by enlarging the water sac, so as to achieve the purpose of effective diversion to prevent the fecal liquid from flowing to the distal intestinal canal, and at the same time prevent the fistula from falling off from the intestinal canal; reducing the size of the water sac by discharging water can make the fistula pass through the tunnel, abdominal wall and intestinal wall of the laparoscopic puncture device smoothly, which is convenient to send the tube into the intestinal wall for catheter ostomy or remove the fistula by the bedside after operation; at the same time, the pain and economic burden caused by the second operation to patients are avoided, and the risk of the second operation is also avoided, 2. through the set socket I and one-way flap, when the syringe is inserted into the socket I, the one-way flap is pushed open at the water outlet end of the syringe, and the size of the water sac can only be changed by injecting or extracting saline from the syringe; after pulling out th¢;50o592 syringe, the one-way flap is closed to prevent water leakage, and the size of the water sac remains unchanged; 3. with the auxiliary branch pipe II and the flushing cavity, the auxiliary branch pipe II has the anti-reflux effect. Once the fecal liquid is viscous and difficult to drain, saline can be injected through the flushing cavity to flush the tip of the drainage cavity, preventing the drainage cavity from being blocked by intestinal feces, resulting in poor drainage, and preventing the reflux of the irrigation liquid; 4. through the set socket I, socket II and socket III, the socket I is convenient for docking the syringe, so that the volume of the water sac can be changed by injecting saline, and meanwhile, a one-way flap leak-proof design is set, so that the syringe will not leak when pulled out, and the size of the water sac will remain unchanged; the socket II is convenient to butt the syringe or install a saline bag to wash the tip of the drainage tube and the intestinal cavity, so as to prevent the viscous fecal liquid from blocking; the socket III is convenient for installing the drainage bag of feces, so as to realize convenient nursing and sanitary operation after operation.

Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the technical field of the present invention. The terminology used in this specification of the present invention is only for the purpose of describing specific embodiments, and is not intended to limit the present invention. As used herein, the term "and/or" includes any and all combinations of one or more related listed items.

Please refer to Fig. 1 to Fig. 4 at the same time. The three-cavity single-sac fistula of ileocecal part includes a tube body 1. One end of the tube body 1 is provided with a round-headed tube tip 2 on its outer wall, and one side of the tube body 1 is sleeved with a water sac 3. Enlarging the water sac 3 can fully divert intestinal contents and fecal liquid to achieve the fistula effect, and at the same time prevent the fistula from falling off. Reducing the water sac 3 can smoothly pass through the abdominal wall and intestinal wall fistula channels, which is convenient for pulling out the fistula after operation, thus realizing the fistula operation with simple operation and little trauma. The tube body 1 is internally provided with a drainage cavity 5, a flushing cavity 8 and a water sac cavity 11; the outer wall of one end of the tube body 1 is provided with a main branch pipe 4, an auxiliary branch pipe I 6 and an auxiliary branch pipe II 7; one end of the auxiliary branch pipe I 6 and the auxiliary branch pipe II 7 is internally provided with a socket I 12 and a socket II 9 respectively; the socket II 9 is internally provided with an anti-reflux flap 10; and the socket I 12 is internally provided with a one-way flap 14. The anti-reflux flap 10 inside the socket II 9 prevents the pollution caused by the reflux of small intestine contents and flushing liquid. The syringe is inserted into the socket I 12, and the one-way flap 14 is pushed open at the water outlet end of the syringe. The size of the water sac 3 can only be changed by injecting or extracting saline from the syringe, and the one-way flap is closed after exiting the syringe, so that the water cannot leak and the size of the water sac remains constant.

Furthermore, one end of the drainage cavity 5 is located inside the main branch pipe 4, one end of the main branch pipe 4 is internally provided with a socket III 13, and the drainage cavity 5 is communicated with the socket III 13, while the other end of the drainage cavity 5 is located inside the round-headed tube tip 2, and the drainage cavity 5 realizes the drainage of the contents of the patients small intestine, achieving the purposes of disconnection, diversion andısg2592 decompression.

Furthermore, one end of the flushing cavity 8 is located inside the round-headed tube tip 2, and the other end of the flushing cavity 8 is located inside the auxiliary branch pipe II 7, and the auxiliary branch pipe II is communicated with the socket II 9. By inputting saline through the flushing cavity 8, the irrigation of the tube tip 2 can be realized, thus preventing the tube tip 2 from being stuck by the contents of the patient's small intestine to block the drainage cavity 5, resulting in the risk of obstruction caused by poor drainage.

Furthermore, one end of the water sac cavity 11 is communicated with the inside of the water sac 3, the other end of the water sac cavity 11 is located in the auxiliary branch pipe I 6, and the water sac cavity 11 is communicated with the inside of the socket I 12. The size of the water sac 3 can be changed by inputting saline into the water sac 3 through the water sac cavity 11, and the one-way flap 14 inside the socket I 12 prevents the liquid inside the water sac 3 from leaking out and the fistula from falling off due to the shrinkage of the water sac.

Furthermore, the water sac 3 has a ring-shaped structure, and the water sac 3 is not communicated with the inside of the pipe body 1. After being filled with water, the ring-shaped structure of the water sac 3 can cling to the inner wall mucosa of the patient's small intestine, which does not damage the intestinal mucosa, and prevents the situation that the inner wall of the patient's small intestine is attached to each other, so as to achieve the best ostomy effect.

Working principle: when in use, after the appendix is removed, the ileocecal three-cavity single-capsule fistula is placed in the final ileum through the cecal wall. In operation, the appendix is removed, and the round-headed tube tip 2 of the ileocecal three-cavity single-capsule fistula is introduced into the abdominal cavity through the laparoscopic main operation hole, and then sent into the final ileum about 20 cm away from the ileocecal valve opening through the appendix root opening, and the double pouches are tightened. According to the size of ileal cavity, inject 15 mL-20 mL saline into the water sac 3 to make the water sac 3 full, fully fit the intestinal canal, close to the water sac 3, sew a needle in the avascular area of the distal mesentery with absorbable thread, and knot it to form a thread ring smaller than the diameter of the water sac 3 to prevent the water sac 3 from sliding. After confirming that the ileum has no ischemia caused by the compression of the water sac 3 and the tight thread ring, sew the double purse string on the abdominal wall to make the appendix opening close to the peritoneal wall. It can effectively adhere to prevent intestinal contents from leaking after operation. After operation, fecal liquid and intestinal liquid are led out from the drainage cavity 5 through the socket III 13, which is convenient to plug into the drainage bag, and the intestinal contents are drained into the drainage bag through the drainage cavity 5. The operation is simple, and the effect of stopping,5p2592 the flow of intestinal contents is exact. If the intestinal contents are too viscous, the auxiliary branch pipe II 7 is flushed through the flushing cavity 8 to prevent the viscous feces from blocking the tube tip 2 and the drainage cavity 5. When flushing, saline is injected into the socket

II 9 through the syringe, and the internal pressure of the socket II 9 increases to open the anti-reflux flap 10, thus realizing the flushing of the round-headed tube tip 2 and the intestinal chamber to prevent the viscous feces from blocking the drainage tube 5. When the syringe is removed or the internal water pressure of the socket II 9 decreases, the anti-reflux flap 10 is closed to prevent intestinal canal leakage or intestinal contents from blocking the flushing cavity; when the size of the water sac 3 needs to be changed, the syringe is inserted into the socket I 12, and the one-way flap 14 is pushed open at the water outlet end of the syringe, so that the size of the water sac 3 can only be changed by injecting or extracting saline from the syringe. After the syringe is pulled out, the one-way flap 14 is closed to prevent water leakage, and the size of the water sac 3 remains unchanged. The one-way flap 14 inside the socket I 12 prevents the leakage of the liquid inside the water sac 3 from causing the fistula to fall off.

The above are only the preferred embodiments of the present invention, but the scope of protection of the present invention is not limited to this. Anyone who is familiar with the technical field, within the technical scope disclosed by the present invention, can equivalently replace or change according to the technical scheme and inventive concept of the present invention, and should be covered in the scope of protection of the present invention.
