[0002] In modern medicine, intestinal surgery is an important means of treating various intestinal diseases. However, the postoperative intestinal healing and recovery process often faces many challenges, such as complications such as infection, anastomotic leakage, and intestinal stenosis. These complications not only prolong the patient's hospital stay and increase medical expenses, but may also have a serious impact on the patient's quality of life. In order to solve these problems, doctors have tried various methods to protect the postoperative healing environment of the intestine. Among them, the use of intestinal protection devices is an effective method because these devices can provide a closed, drainable environment, reduce irritation to the intestinal sutures, promote healing, and reduce the risk of infection. However, existing intestinal protection devices still have some shortcomings. Some devices have poor fixation effects and are prone to displacement or leakage during intestinal peristalsis, which may cause the device to fail to effectively play its protective and drainage role, resulting in accumulation of intestinal contents and increased risk of infection, which may further prolong the patient's recovery time and may have adverse effects on the patient's health.

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0022] An embodiment of the present invention provides a rectal protection device for post-intestinal surgery, which includes: a closed tube 1 and a drainage tube 2 matched with the closed tube 1; wherein a plurality of groups of iron powders 11 are arranged inside the closed tube 1 in the direction along the rotation axis, and each group of iron powders 11 are equidistantly distributed; an attraction head 21 is connected to one end of the drainage tube 2, and a plurality of magnetic powders 22 are installed on the outside of the attraction head 21, and the iron powders 11 and the magnetic powders 22 attract each other; a support component is arranged on the inner side of the closed tube 1, and the closed tube 1 can be propped up or contracted by the support component; a fixing component is slidably connected to the outer side of the drainage tube 2, and the drainage tube 2 can be fixed to the patient's body surface by the fixing component.

[0023] It should be noted that: inside the closed tube 1, multiple groups of iron powder 11 are evenly arranged along the direction of its rotation axis, and each group of iron powder 11 is equidistantly distributed to ensure the consistency of the magnetic attraction effect. A plurality of magnetic powders 22 are installed on the outside of the attraction head 21, and these magnetic powders 22 attract each other with the iron powder 11 inside the closed tube 1, thereby achieving a stable fixation and precise positioning of the closed tube 1. The support assembly is placed on the inner side of the closed tube 1 to maintain the shape and position of the closed tube 1 by providing the necessary support force. The support assembly has the ability to prop up or shrink the closed tube 1 so that it can pass smoothly and adapt to the shape of the intestine when it is sent into the intestine. The fixing assembly is located on the outside of the drainage tube 2 and is firmly fixed to the drainage tube 2 by a sliding connection. The fixing assembly is used to fix the drainage tube 2 on the patient's body surface to prevent it from shifting during use, thereby ensuring the stability and reliability of the drainage process. The drainage tube 2 is a prior art and is not described in detail here.

[0024] In an embodiment of the present invention, one end of the closed tube 1 is connected to an air intake pipe 12, and a one-way valve is installed in the air intake pipe 12. The side of the air intake pipe 12 away from the closed tube 1 is connected to an air supply pipe 13 through plugging. The side of the air supply pipe 13 away from the air intake pipe 12 is connected to a pressing handle 14.

[0025] It should be noted that: the air inlet pipe 12 is connected to one end of the closed tube 1, and is used to inflate the closed tube 1 so that the closed tube 1 expands and is fixed in the intestine. A one-way valve is installed inside the air inlet pipe 12 to control the flow direction of the gas and prevent the gas from flowing back, thereby ensuring the smooth progress of the inflation process. The air supply pipe 13 is connected to the air inlet pipe 12 by plugging, and is used to transport gas. This connection method is convenient, fast and easy to operate. A pressing handle 14 is connected to the side of the air supply pipe 13 away from the air inlet pipe 12, which is used to manually control the delivery of gas. By pressing the handle 14, medical staff can easily inflate the air supply pipe 13, and the gas then enters the closed tube 1 through the air inlet pipe 12, so that the closed tube 1 expands and is firmly fixed in the intestine.

[0026] In the embodiment of the present invention, the sealing tube 1 is an airbag with a hollow structure, and the outer side of the airbag is a corrugated structure.

[0027] It should be noted that the closed tube 1 is designed as an airbag with a hollow structure, which not only facilitates the circulation of objects in the intestine and prevents contamination of intestinal wounds, but also can adapt to the shape of the intestine through the expansion of the airbag to provide a better fit. The outer side of the airbag is a corrugated structure, and the corrugations at one end are distributed horizontally, and the corrugations at the other end are distributed longitudinally. This design can cooperate with the inner wall of the intestine to effectively prevent displacement or leakage caused by intestinal peristalsis. The corrugated structure also increases the contact area between the airbag and the inner wall of the intestine, thereby providing a better fixation effect and enhancing the stability and reliability of the device in the intestine. In addition, the airbag with a corrugated structure can also reduce the irritation to the inner wall of the intestine and improve the comfort of the patient.

[0028] In the embodiment of the present invention, a protective cover 23 is connected to one end of the drainage tube 2 close to the suction head 21, and the protective cover 23 is located outside the magnetic powder 22, and the protective cover 23 is made of phosphate material.

[0029] It should be noted that a protective cover 23 is connected to one end of the drainage tube 2 close to the suction head 21, and the protective cover 23 is located on the outside of the magnetic powder 22. The protective cover 23 is made of phosphate material, which has excellent biocompatibility and degradability, can coexist harmoniously with human tissue in medical applications, and finally decompose safely in the body. By using phosphate material, the protective cover 23 can effectively protect the magnetic powder 22 and prevent it from directly contacting the intestinal tissue, thereby reducing irritation and potential damage to the intestine. This design not only improves the patient's comfort, but also helps promote the postoperative healing process and reduce the risk of infection and other complications.

[0030] In an embodiment of the present invention, the support assembly includes a support tube 3, and the support tube 3 is located on the inner side of the closed tube 1, one end of the support tube 3 is connected to a connecting tube 31, and the outer side of the connecting tube 31 away from the closed tube 1 is connected to a grasping portion 32, a bidirectional screw 33 is rotatably connected inside the support tube 3, both ends of the outer side of the bidirectional screw 33 are threadedly connected to thread blocks 34, one end of the bidirectional screw 33 is connected to a driving rod 35, the end of the driving rod 35 away from the bidirectional screw 33 passes through the connecting tube 31 and is connected to a knob 36, the two thread blocks 34 are connected with traction rods 4 around, the circumference of the support tube 3 is provided with traction grooves 41 for the traction rods 4 to slide, the circumference of the support tube 3 is provided with support plates 42, and each of the support plates 42 is connected to two of the traction rods 4 on the side close to the support tube 3.

[0031] It should be noted that the support tube 3 is located on the inner side of the closed tube 1 to form a tubular structure for providing support and stability. The outer side of the connecting tube 31 away from one end of the closed tube 1 is connected with a gripping portion 32, which is convenient for medical staff to operate and adjust. The outer ends of the bidirectional screw 33 are both threadedly connected with thread blocks 34, which are used to drive the traction rod 4 to move, thereby adjusting the position of the support plate 42. One end of the bidirectional screw 33 is connected with a drive rod 35, which is used to transmit rotational power. By manually rotating the knob 36, the bidirectional screw 33 can be driven to rotate. The end of the drive rod 35 away from the bidirectional screw 33 passes through the connecting tube 31 and is connected with a knob 36, so that medical staff can conveniently perform manual operation. The four sides of the two thread blocks 34 are connected with traction rods 4, which are used to drive the support plate 42 to move, thereby adjusting the size and direction of the supporting force. The circumferential side of the support tube 3 is provided with traction grooves 41 for the traction rods 4 to slide. These traction grooves 41 are used to guide the movement of the traction rods 4 to ensure their stability and accuracy during movement. Each support plate 42 is connected to two of the traction rods 4 on one side close to the support tube 3. Through this connection mode, the support plate 42 can provide the necessary support force to facilitate the support of the closed tube 1 and prevent it from falling off when it is sent into the intestine. By rotating the knob 36, the drive rod 35 drives the bidirectional screw 33 to rotate, so that the threaded block 34 moves along the bidirectional screw 33, thereby driving the traction rod 4 to slide in the traction groove 41, so that the support plate 42 moves inward or outward, and the support force is adjusted to make the closed tube 1 propped up or contracted, so that the closed tube 1 can be smoothly sent into the intestine.

[0032] In an embodiment of the present invention, the fixing assembly includes a fixing tube 5 arranged on the outside of the drainage tube 2, the inner side of the fixing tube 5 is slidably connected to the outer side of the drainage tube 2, the outer side of the fixing tube 5 is connected to a limiting ring 51, and the limiting ring 51 is located in the fixing tube 5, the outer side of the drainage tube 2 is sleeved with two return springs 52, and the two return springs 52 are respectively located on both sides of the limiting ring 51, and the two return springs 52 are both located on the inner side of the fixing tube 5, the outer side of the fixing tube 5 is connected to an adhesive plate 53, and adhesive tape 54 is installed around the adhesive plate 53.

[0033] It should be noted that the fixed assembly includes a fixed tube 5 arranged on the outside of the drainage tube 2, which is used to fix the position of the drainage tube 2. The inner side of the fixed tube 5 is slidably connected to the outer side of the drainage tube 2 to allow the drainage tube 2 to move in the fixed tube 5, provide space for the intestine to peristalsis, and ensure the stability and reliability of the drainage tube 2. A limit ring 51 is connected to the outside of the fixed tube 5, and the limit ring 51 is located in the fixed tube 5, which is used to limit the sliding range of the drainage tube 2 to prevent it from excessive movement. Two reset springs 52 are sleeved on the outside of the drainage tube 2, and the two reset springs 52 are respectively located on both sides of the limit ring 51. These reset springs 52 are used to provide a reset force, and when the intestine peristsals, the iron powder 11 and the magnetic powder 22 can interact to pull the drainage tube 2 to move. Specifically, when the intestine peristsals, the closed tube 1 may move accordingly. Since multiple groups of iron powder 11 are arranged inside the closed tube 1, and multiple magnetic powders 22 are installed on the outside of the suction head 21 of the drainage tube 2, there is a mutual attraction between the iron powder 11 and the magnetic powder 22. Therefore, when the closed tube 1 moves, the attraction between the iron powder 11 and the magnetic powder 22 will pull the drainage tube 2 to move with it. At this time, the role of the reset spring 52 is particularly important. Even if the intestines peristalsis, the drainage tube 2 can maintain its fixed position and continue to effectively pull to prevent the closed tube 1 from falling off. The reset spring 52 can also provide a certain buffering effect, reducing the impact force on the drainage tube 2 during the movement, thereby protecting the drainage tube 2 and its connected suction head 21 and other components, and extending its service life. In order to fix the fixed tube 5 to the patient's body surface, an adhesive plate 53 is connected to the outside of the fixed tube 5. An adhesive tape 54 is installed on the adhesive plate 53 to enhance the bonding effect and ensure a firm connection between the fixed tube 5 and the patient's body surface. The adhesive tape 54 is evenly distributed around to provide a full range of bonding force to prevent the fixed tube 5 from shifting or falling off during use.

[0034] The working principle of the rectal protective device for intestinal surgery provided by the present invention is as follows: First, a drainage port is opened near the patient's affected part for placing the drainage tube 2. Then, the closed tube 1 is expanded by the support component to prevent it from falling off when it is sent into the intestine, thereby ensuring its stability and reliability in the intestine. The closed tube 1 is passed from the anus into the rectum through the connecting tube 31 to reach the suture site or the affected part. By pressing the handle 14 to inflate the air supply tube 13, the gas enters the closed tube 1 through the air inlet pipe 12, so that the closed tube 1 expands and is firmly fixed in the intestine, providing reliable support and sealing effect. After the inflation is completed, the air supply tube 13 is separated from the air inlet pipe 12. The drainage tube 2 is inserted into the patient's body through the pre-set drainage port, and is fixed to the patient's body surface by the fixing component to ensure its stability during use. The magnetic powder 22 on the drainage tube 2 and the iron powder 11 inside the closed tube 1 attract each other to achieve the fixation of the closed tube 1, providing precise positioning and reliable fixing effect. Finally, by rotating the knob 36, the driving rod 35 drives the bidirectional screw 33 to rotate, so that the threaded block 34 moves along the bidirectional screw 33, thereby driving the traction rod 4 to slide in the traction groove 41, so that the support plate 42 moves inward or outward, and the support force is adjusted to shrink the sealing tube 1 so as to be safely removed from the intestine. The setting of the sealing tube 1 can achieve effective protection and drainage of the intestine, improve the postoperative rehabilitation effect, and relieve the patient's pain.
