Description

Technical Field

[0001] The present invention relates to the technical field of gastrointestinal decompression nursing, and particularly to an intraoperative gastrointestinal decompressor. Background Art

[0002] Intestinal obstruction is a common acute abdomen in clinical practice, referring to the obstruction of intestinal contents during passage through the intestine, resulting in a large accumulation of gas and liquid in the intestinal lumen, and thus causing symptoms such as abdominal distension, abdominal pain, and vomiting.

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

[0004] Traditional intestinal decompression methods mainly include two ways: nasogastric tube decompression and insertion of an intestinal obstruction catheter. Nasogastric tube decompression drains the gas and liquid in the gastrointestinal tract through nasal intubation to relieve abdominal distension and reduce intestinal pressure; however, for low - level 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, usually inserted through the nose under endoscopy or fluoroscopy. The water balloon at the front end of the catheter can gradually advance close to the obstruction site through its own gravity and intestinal peristalsis, continuously sucking the intestinal contents above the obstruction, thereby effectively decompressing; however, the insertion of the intestinal obstruction catheter requires professional equipment and technical support, the operation is complex, and in some cases, it may not be able to reach the expected position smoothly, affecting the decompression effect.

[0006] In addition, intestinal wall can be directly incised during the operation for decompression, but due to the high intestinal pressure, intestinal contents are likely to spurt out when the intestinal wall is incised, 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 an intestinal tube decompression puncture device. The usage method is to make a purse - string suture on the intestinal tube, cut a small opening, insert a blunt puncture head into the intestinal cavity, then tighten the purse - string suture, and finally connect a negative pressure aspirator for decompression; however, such devices require combined purse - string suture for the fixation of the decompression device, the operation difficulty is large, and they may not be able to effectively handle larger solid intestinal contents, with limited decompression effect; moreover, the puncture structure of the existing decompression devices generally cannot be detached from the main body, and there is a possibility of damaging the internal intestinal cavity or even penetrating the intestinal cavity; therefore, it is urgent to solve. Summary of the Invention

[0007] Aiming at the current situation of the above - mentioned existing technologies, the technical problem to be solved by the present invention is to provide an intraoperative gastrointestinal decompressor that not only reduces the operation difficulty and complexity, but also can handle larger solid - shaped intestinal contents to expand the scope of application and greatly improve the decompression effect, and also effectively speeds up the surgical progress and improves the surgical safety and success rate.

[0034] In order to keep the following description of the embodiments of the present invention clear and concise, the detailed descriptions of known functions and known components are omitted in the present invention.

[0035] As Figures 1 to 6 shown, a gastrointestinal decompressor during surgery includes a positioner 1 and a suction device 2 detachably disposed inside the positioner 1;

[0036] The positioner 1 includes a vertically arranged positioning tube 11, a positioning ring 12 sleeved and fixed outside the positioning tube 11, and at least two arc-shaped air bags 13 disposed on the outer peripheral surface of the positioning tube 11 and evenly distributed at equal angles along the circumferential direction;

[0037] The aspirator 2 includes a hard tube 21 arranged vertically, a base 24 that is sealed and detachably fixed at the lower opening of the hard tube 21 and is located outside the lower end of the positioning tube 11, a flexible tube 22 that is hermetically connected to the upper opening of the hard tube 21 and communicates with the inside of the hard tube 21, and a drainage tube 23 that is hermetically inserted into the side surface of the lower end of the hard tube 21 and communicates with the inside of the hard tube 21;

[0038] The upper end of the hard tube 21 is concentrically and hermetically inserted into the inside of the positioning tube 11 so that the flexible tube 22 extends to the outside of the upper end of the positioning tube 11 after passing through the inside of the positioning tube 11;

[0039] It also includes a puncture needle 6 or a medical clamp 5 that is detachably inserted into the hard tube 21.

[0040] Circumferentially distributed grooves 113 are formed on the outer peripheral surface of the positioning tube 11, and the edge of the opening of each arc-shaped airbag 13 is hermetically fixed on the annular bottom surface of the groove 113.

[0041] A plurality of counterbores 111 are formed at the lower end of the positioning tube 11. The number of the counterbores 111 is equal to the number of the arc-shaped airbags 13. The bottom of each counterbore 111 extends to the inside of a corresponding arc-shaped airbag 13. A through hole 112 is formed between the inner wall of each counterbore 111 and the annular bottom surface of the groove 113. The outer opening of each through hole 112 communicates with the inside of a corresponding arc-shaped airbag 13.

[0042] An auxiliary device 3 is also provided on the locator 1. The auxiliary device 3 includes a positioning sleeve 31 that is movably sleeved outside the positioning tube 11 and is located above each arc-shaped airbag 13, a traction sleeve 32 that is movably sleeved outside the positioning tube 11 and is located below the positioning ring 12, a plurality of traction rods 33 that are vertically inserted and connected in the positioning ring 12 and are sequentially and equidistantly arranged around the periphery of the positioning tube 11 in the circumferential direction, and a return spring 34 that is sleeved outside the plurality of traction rods 33 and is located between the positioning ring 12 and the traction sleeve 32. The return spring 34 is always in a compressed state to make the positioning sleeve 31 always have a tendency to move downward by means of the traction sleeve 32 and each traction rod 33.

[0043] The number of the traction rods 33 is equal to the number of the 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.

[0044] An annularly arranged conical surface 311 is formed on the inner edge of the lower opening of the positioning sleeve 31.

[0045] An annularly arranged limiting ring 114 is also formed outward on the outer peripheral surface of the upper end of the positioning tube 11.

[0046] At the opening of each counterbore 111, a ventilation pipe 4 is also hermetically inserted.

[0047] The locator 1 further includes an elastic shrinkage ring 8 embedded inside the upper opening of the positioning pipe 11. The upper end of the rigid pipe 21 is inserted through the elastic shrinkage ring 8 so that the elastic shrinkage ring 8 hermetically wraps around the outer wall of the rigid pipe 21 by virtue of its own elasticity.

[0048] Usage method:

[0049] In the initial state, the inside of each arc-shaped airbag 13 is in an uninflated state, and each uninflated arc-shaped airbag 13 can be compressed into the inside of the groove 113 after contraction. The positioning sleeve 31 moves downward to the outside of the groove 113 under the rebounding force of the return spring 34 and wraps each uninflated arc-shaped airbag 13 inside it.

[0050] During the operation, first make a break 71 on the outside of the intestine 7, then pass one end of the positioning pipe 11 where the limiting ring 114 is located through the break 71 and extend it into the inside of 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 both located inside the intestine 7.

[0051] Then press the traction sleeve 32 towards the positioning sleeve 31 to drive the positioning sleeve 31 to move towards the limiting ring 114 and gradually leave the groove 113 by means of each traction rod 33 until one 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 the above state needs to be maintained. During this process, the return spring 34 is gradually compressed.

[0052] Then, inject air into each ventilation pipe 4 in turn with a needleless syringe, so that the air enters the inside of the arc-shaped airbag 13 through the counterbore 111 and the through hole 112, thereby inflating and expanding each arc-shaped airbag 13. After filling, pull out the needleless syringe and seal each ventilation pipe 4, thus completing the inflation of each arc-shaped airbag 13.

[0053] Subsequently, slowly release the traction sleeve 32. The rebounding force of the return spring 34 is gradually released and pushes the traction sleeve 32 to move away from the intestine 7, thereby driving the positioning sleeve 31 to move towards each arc-shaped airbag 13 by means of each traction rod 33, so that the conical surface 311 on the positioning sleeve 31 slowly presses the upper outer wall of each arc-shaped airbag 13, and thus each arc-shaped airbag 13 deforms downward, so that the lower side of each arc-shaped airbag 13 is tightly pressed against the inner wall of the intestine 7. In this way, the elastic pressing of each arc-shaped airbag 13 against the inner wall of the intestine 7 is realized, and then the locator 1 is fixed on the intestine 7.

[0054] 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 create negative pressure inside both the rigid tube 21 and the flexible tube 22 through the drainage tube 23. Subsequently, the medical staff manually presses the intestine 7 on both sides of the break 71 to gradually squeeze the intestinal contents inside the intestine 7 towards the direction of the flexible tube 22. When the intestinal contents approach the end opening of the flexible tube 22, the intestinal contents will be sucked into the flexible tube 22 by the negative pressure inside the flexible tube 22, and then enter the rigid tube 21, and thus be discharged outward through the drainage tube 23.

[0055] In addition, when other related operations need to be performed inside the intestine 7, the base 24 can also be removed, and then other medical devices such as the puncture needle 6 or the medical clamp 5 are sequentially passed through the rigid tube 21 and the flexible tube 22 and probed into the intestine 7.

[0056] When the rigid tube 21 passes through the elastic contraction ring 8, the opening of the elastic contraction ring 8 will expand by its own elasticity and tightly wrap around the outer wall of the rigid tube 21 to achieve sealing. When the rigid tube 21 leaves the elastic contraction ring 8, the opening of the elastic contraction ring 8 will shrink and close by its own elasticity, thereby effectively preventing the intestinal contents in the rigid tube 21 from flowing back into the intestine 7 when the rigid tube 21 leaves.

[0057] 1. The present invention firmly fixes the locator 1 on the intestine 7 by the mutual cooperation of multiple arc-shaped air bags 13 and the positioning ring 12, without the need to perform purse-string suture on the intestinal tube, thereby reducing the operation difficulty and complexity.

[0058] 2. The puncture needle 6 of the present invention adopts a detachable structure, which can effectively avoid intestinal injuries caused by factors such as improper operation, and can be replaced with a medical clamp 5 to handle larger solid-shaped intestinal contents, thereby expanding the scope of application and significantly improving the decompression effect.

[0059] 3. The present invention also limits the depth of the positioning tube 11 extending into the intestine 7 by means of the positioning ring 12, thereby avoiding intestinal cavity injuries caused by the positioning tube 11 extending excessively into the intestinal cavity; at the same time, the upper end opening of the positioning tube 11 is also permanently closed by the elastic contraction ring 8, thereby effectively preventing the contents in the rigid tube 21 from flowing back.

[0060] 4. The present invention can elastically compress the periphery of the break 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 break 71, thus effectively avoiding the pollution of the surgical area; at the same time, the hands of the medical staff will not directly contact the intestinal contents during the whole process of use, thereby avoiding the steps of having to change gloves multiple times during the operation due to contact with the intestinal contents in the past, thus effectively accelerating the surgical progress.

[0061] 5. The operation of the present invention is convenient and its functions are perfect. It can safely and effectively reduce the pressure in the intestinal cavity during the operation to prevent the intestinal contents from contaminating the surgical area, and has the ability to handle solid intestinal contents to improve the safety and success rate of the operation.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
