Description

Technical Field

[0001] The invention relates to the technical field of gastrointestinal decompression nursing, and in particular to an intraoperative gastrointestinal decompression device. Background Art

[0002] Intestinal obstruction is a common acute abdomen in clinical practice. It refers to the obstruction of intestinal contents when passing through the intestine, resulting in the accumulation of a large amount of gas and fluid in the intestinal cavity, which in turn causes symptoms such as abdominal distension, abdominal pain, and vomiting.

[0003] During the surgical treatment of intestinal obstruction, decompression is a key step, which aims to reduce the pressure in the intestinal cavity, prevent intestinal wall ischemia and necrosis, and reduce postoperative complications.

[0004] Traditional intestinal decompression methods mainly use two methods: nasogastric tube decompression and intestinal obstruction catheter insertion. Nasogastric tube decompression drains gas and fluid in the gastrointestinal tract through nasal intubation to relieve abdominal distension and reduce intestinal pressure. However, for low small intestinal obstruction, the decompression effect of the nasogastric tube is limited, and it is difficult to relieve symptoms in a timely and effective manner.

[0005] The intestinal obstruction catheter is a relatively advanced decompression tool, which is usually inserted through the nose under endoscopy or X-ray fluoroscopy. The water bag at the front end of the catheter can be gradually pushed to the site close to the obstruction through its own gravity and intestinal peristalsis, and continuously attract the intestinal contents above the obstruction, thereby effectively reducing pressure. However, the insertion of the intestinal obstruction catheter requires professional equipment and technical support, the operation is complicated, and in some cases it may not reach the expected position smoothly, affecting the decompression effect.

[0006] In addition, the intestinal wall can be directly cut during the operation to reduce pressure. However, due to the high pressure in the intestine, cutting the intestinal wall can easily cause intestinal contents to spray out, contaminating the surgical area and increasing the risk of postoperative infection. For this reason, some improved decompression devices have been designed on the market, such as intestinal decompression puncture devices, which are used by first making a purse-string suture on the intestinal tube, making a small incision, inserting the blunt puncture head into the intestinal cavity, tightening the purse-string line, and finally connecting a negative pressure aspirator for decompression. However, this type of device requires a purse-string suture to fix the decompression device, which is difficult to operate and may not be able to effectively handle larger solid intestinal contents, resulting in limited decompression effect. In addition, the puncture structure of the existing decompression device generally cannot be detached from the main body, and there is a possibility of damaging the inside of the intestinal cavity or even penetrating the intestinal cavity. Therefore, it is urgently needed to be solved. Summary of the invention

[0007] In view of the current status of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide an intraoperative gastrointestinal decompression device which not only reduces the difficulty and complexity of operation, but also can handle larger solid intestinal contents to expand the scope of application and greatly improve the decompression effect, and also effectively speeds up the progress of the operation and improves the safety and success rate of the operation.

[0024] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0025] like Figures 1 to 6 As shown, an intraoperative gastrointestinal decompression device comprises a positioner 1 and a detachable suction device 2 disposed inside the positioner 1; The positioner 1 comprises a vertically arranged positioning tube 11, a positioning ring 12 sleeved and fixed on the outside of the positioning tube 11, and at least two arc-shaped air bags 13 arranged on the outer circumference of the positioning tube 11 and evenly distributed at equal angles along the circumferential direction; The suction device 2 includes a vertically arranged hard tube 21, a base 24 which is sealed and detachably fixed at the lower end opening of the hard tube 21 and is located outside the lower end of the positioning tube 11, a hose 22 which is sealed and connected to the upper end opening of the hard tube 21 and communicates with the inside of the hard tube 21, and a drainage tube 23 which is sealed and plugged into the side surface of the lower end of the hard tube 21 and communicates with the inside of the hard tube 21. The upper end of the hard tube 21 is inserted concentrically and sealed inside the positioning tube 11 so that the hose 22 extends to the outside of the upper end of the positioning tube 11 after passing through the interior of the positioning tube 11; It also includes a detachable puncture needle 6 or a medical clamp 5 which is inserted into the hard tube 21 .

[0026] An circumferentially distributed groove 113 is formed on the outer peripheral surface of the positioning tube 11 , and the edge of the opening of each arc-shaped airbag 13 is sealed and fixed on the annular bottom surface of the groove 113 .

[0027] A plurality of countersunk holes 111 are provided at the lower end of the positioning tube 11, and the number of the countersunk holes 111 is equal to the number of the arc-shaped airbags 13. The bottom of each countersunk hole 111 extends to the inner side of a corresponding arc-shaped airbag 13. A through hole 112 is provided between the inner wall of each countersunk hole 111 and the annular bottom surface of the groove 113, and the outer opening of each through hole 112 is interconnected with the interior of a corresponding arc-shaped airbag 13.

[0028] The positioner 1 is also provided with an auxiliary device 3, which includes a positioning sleeve 31 movably sleeved on the outside of the positioning tube 11 and located above each arc-shaped airbag 13, a traction sleeve 32 movably sleeved on the outside of the positioning tube 11 and located below the positioning ring 12, a plurality of traction rods 33 vertically inserted and connected in the positioning ring 12 and circumferentially and evenly spaced around the outer periphery of the positioning tube 11, and a return spring 34 sleeved on the outside of the plurality of traction rods 33 and located between the positioning ring 12 and the traction sleeve 32. The return spring 34 is always in a compressed state to enable the positioning sleeve 31 to always have a tendency to move downward with the help of the traction sleeve 32 and each traction rod 33.

[0029] The number of traction rods 33 is equal to the number of arc-shaped airbags 13 . The upper end of each traction rod 33 passes through the gap between two adjacent arc-shaped airbags 13 and is fixed to the lower end of the positioning sleeve 31 . The lower end of each traction rod 33 is fixed to the upper end of the traction sleeve 32 .

[0030] A conical surface 311 is formed circumferentially on the inner edge of the lower opening of the positioning sleeve 31 .

[0031] The outer peripheral surface of the upper end of the positioning tube 11 is also formed with a circumferentially arranged limiting ring 114 outwardly.

[0032] A vent pipe 4 is also sealed and plugged into the opening of each counterbore 111 .

[0033] The positioner 1 also includes an elastic shrink ring 8 embedded in the upper opening of the positioning tube 11. The upper end of the hard tube 21 is inserted into the elastic shrink ring 8 so that the elastic shrink ring 8 is wrapped around the outer wall of the hard tube 21 by its own elastic sealing.

[0034] Directions: In the initial state, the interior of each arc-shaped airbag 13 is in an uninflated state, and each uninflated arc-shaped airbag 13 can be compressed into the interior of the groove 113 after shrinkage. The positioning sleeve 31 moves downward to the outside of the groove 113 under the rebound force of the return spring 34 and wraps each uninflated arc-shaped airbag 13 inside it.

[0035] During the operation, a rupture 71 is opened on the outside of the intestine 7, and then one end of the positioning tube 11 where the limiting ring 114 is located is passed through the rupture 71 and extended into the intestine 7 until the outer wall of the intestine 7 contacts the positioning ring 12. At this time, the groove 113 and each uninflated arc-shaped airbag 13 in the groove 113 are located inside the intestine 7.

[0036] Then, the traction sleeve 32 is pressed toward the positioning sleeve 31 to drive the positioning sleeve 31 to move toward the limiting ring 114 with the help of each traction rod 33 and gradually leave the groove 113 until the end of the positioning sleeve 31 facing the limiting ring 114 abuts against the limiting ring 114. At this time, the traction sleeve 32 completely leaves the groove 113 and needs to maintain the above state. During this process, the return spring 34 is gradually compressed.

[0037] Next, air is pumped into each ventilation tube 4 in turn with the help of a needle-free syringe, and then the air enters the interior of the arc-shaped airbag 13 through the countersunk hole 111 and the through hole 112, so that each arc-shaped airbag 13 is inflated. After being full, the needle-free syringe is pulled out and each ventilation tube 4 is closed, thereby completing the inflation of each arc-shaped airbag 13.

[0038] Then, the traction sleeve 32 is slowly loosened, and the rebound force of the reset spring 34 is gradually released and pushes the traction sleeve 32 to move away from the intestine 7, and then, with the help of each traction rod 33, the positioning sleeve 31 is driven to move toward the direction of each arc-shaped airbag 13, so that the conical surface 311 on the positioning sleeve 31 slowly presses the upper outer wall of each arc-shaped airbag 13, and then each arc-shaped airbag 13 is deformed downward, so that the lower side of each arc-shaped airbag 13 is pressed against the inner wall of the intestine 7, so that each arc-shaped airbag 13 can elastically press the inner wall of the intestine 7, thereby fixing the locator 1 on the intestine 7.

[0039] Connect the air inlet of the vacuum extractor to the end opening of the drainage tube 23. After starting the vacuum extractor, the vacuum extractor will generate negative pressure inside the hard tube 21 and the soft tube 22 with the help of the drainage tube 23; then, the medical staff will press the intestine 7 on both sides of the rupture 71 by hand to gradually squeeze the intestinal contents inside the intestine 7 toward the direction of the soft tube 22. When the intestinal contents are close to the end opening of the soft tube 22, the intestinal contents will be sucked into the inside of the soft tube 22 by the negative pressure in the soft tube 22, and then enter the hard tube 21, and then be discharged outward through the drainage tube 23.

[0040] In addition, when other related operations need to be performed on the inside of the intestine 7, the base 24 can be removed, and then other medical devices such as the puncture needle 6 or the medical clamp 5 can be passed through the hard tube 21 and the soft tube 22 in sequence to probe into the inside of the intestine 7.

[0041] When the hard tube 21 passes through the elastic shrink ring 8, the opening of the elastic shrink ring 8 will expand with the help of its own elasticity and tightly wrap around the outer wall of the hard tube 21 to achieve sealing. When the hard tube 21 leaves the elastic shrink ring 8, the opening of the elastic shrink ring 8 will shrink and close with the help of its own elasticity, thereby effectively preventing the intestinal contents in the hard tube 21 from flowing back into the intestine 7 when the hard tube 21 leaves.

[0042] 1. The present invention securely fixes the positioner 1 on the intestine 7 by means of the cooperation between the multiple arc-shaped airbags 13 and the positioning ring 12, and does not require purse-string suture on the intestine, thereby reducing the difficulty and complexity of the operation.

[0043] 2. The puncture needle 6 of the present invention adopts a detachable structure, which can effectively avoid intestinal damage caused by improper operation and other factors. It can be replaced by a medical clamp 5 to handle larger solid intestinal contents, thereby expanding the scope of application and greatly improving the decompression effect.

[0044] 3. The present invention also uses the positioning ring 12 to limit the depth of the positioning tube 11 extending into the intestine 7, thereby preventing the positioning tube 11 from causing damage to the intestinal cavity due to excessive extension into the intestinal cavity; at the same time, the elastic shrink ring 8 is used to permanently seal the upper end opening of the positioning tube 11, thereby effectively preventing the contents in the hard tube 21 from flowing back.

[0045] 4. The present invention can elastically compress the area around the rupture 71 on the intestine 7 with the aid of the auxiliary device 3, thereby effectively preventing the intestinal contents from leaking out of the intestine through the rupture 71, thereby effectively avoiding contamination of the surgical area; at the same time, the hands of medical staff will not directly contact the intestinal contents during the entire process of use, thereby avoiding the need to change gloves multiple times during surgery due to contact with intestinal contents, thereby effectively speeding up the progress of the surgery.

[0046] 5. The present invention is easy to operate and has complete functions. It can safely and effectively reduce the pressure in the intestinal cavity during surgery to prevent intestinal contents from contaminating the surgical area, and has the ability to process solid intestinal contents to improve the safety and success rate of the surgery.
