Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a low rectal tension reducing anal tube. BACKGROUND

[0002] Intestinal-intestinal anastomotic fistula after rectal surgery is one of the most common and most difficult clinical problems in colorectal surgery, and serious complications are anastomotic leakage. High intraluminal pressure is one of the risk factors for colorectal anal anastomotic leakage. Due to continuous feces entering the fistula from the intestinal cavity, the traditional treatment method basically relies on reoperation of fistula surgery. In recent years, we can let some patients avoid reoperation of fistula surgery by placing a flushing tube through the fistula, but due to continuous feces entering the fistula from the intestinal cavity, some patients still have poor local drainage, prolonged hospitalization time, and other adverse conditions, and even some patients have to undergo fistula surgery again, resulting in incomplete fistula cavity flushing and drainage, and secondary local or systemic infection, eventually leading to fistula cavity cannot be localized. Many patients ultimately have to undergo two-stage fistula surgery. Intraluminal gas and fluid can cause poor blood supply to the intestinal tube, excessive tension of the anastomotic stoma, and accumulation of feces near the anastomotic stoma, which is not conducive to anastomotic healing. Therefore, effective and timely discharge of gas, liquid and feces in the intestinal cavity is beneficial to anastomotic healing, but the device is not easy to operate. At the same time, after some rectal surgery, a fecal storage bag is set up to store the feces of the patient, but the current fecal storage bag does not have support and is easy to tear and cause injury. At the same time, when the patient is lying down, the fecal storage bag will also lie down, which is easy to cause the feces or some liquid in the fecal storage bag to flow back, affecting the patient.

[0003] In view of the above problems, the present application provides a low rectal tension reducing anal tube to solve the above problems. SUMMARY

[0004] In order to solve the problem that feces continuously enter the fistula from the intestinal cavity, and some patients still have poor local drainage, prolonged hospitalization time and other adverse conditions, the present application aims to provide a low rectal tension reducing anal tube.

It is convenient to position the fixed cover for different patients.

[0007] Preferably, an anastomosis ring is arranged between the second water bag and the mounting sleeve. The structures on the anal canal above the anastomosis ring are located inside the anus, and the structures below the anastomosis ring are located outside the anus. The anastomosis ring is used to distinguish the position of the anal canal inside and outside the anus, so that the staff can make a judgment. At the same time, the anastomosis ring also represents the position, which is convenient for the staff to install the anal canal and for medical staff to make corresponding adjustments.

[0008] Preferably, the fecal storage bag has connecting straps on both sides, which are elastically stretchable. A first strap and a second strap are fixedly attached to the end of each connecting strap away from the fecal storage bag. Both the first and second straps are elastically stretchable. A first Velcro closure is provided on the inner side of the first strap, and a second Velcro closure is provided on the front of the second strap to adhere to the first Velcro closure. The first and second straps at both ends of the connecting strap are wrapped around the thigh, distributing part of the weight of the fecal storage bag to the patient's thigh and preventing tearing at the anus. A carrying strap is provided on one side of the fecal storage bag. A horizontal plate parallel to the fecal storage bag is provided on the side of the fecal storage bag away from the carrying strap. The horizontal plate is a lightweight plate, and a connecting block is fixedly attached to the bottom of the horizontal plate.

A groove is formed on the side of the horizontal plate facing the fecal storage bag, and a screw rod is rotatably mounted in the groove. A moving block is threaded onto the screw rod. A first rotating block is provided on the side of the moving block facing the fecal storage bag. A first rotating block is installed on the side of the fecal storage bag facing the horizontal plate. The first and second rotating blocks are diagonally distributed. They are actually two hinged rotating bodies, allowing one end to be fixed while the other can rotate normally. A top rod is fixed between the first and second rotating blocks. The top rod is rigid and initially tilted. To ensure the storage bag remains tilted and prevent backflow of feces and liquids, a rotating wheel drives a lead screw to rotate. The lead screw moves a threaded movable block, causing the first rotating block on the movable block to move towards the second rotating block. The top rod between the first and second rotating blocks gradually becomes vertical. Pushed by the top rod and the second rotating block, the storage bag gradually tilts, preventing backflow of stored feces when the bag is flat, thus avoiding unnecessary impact on the patient. A rotating wheel is rotatably mounted on the end of the lead screw near the movable block, allowing staff to easily drive the lead screw for convenient operation.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] 1. This invention uses a first and second water balloon to block the proximal intestinal segment, fully draining feces and reducing the direct impact of fecal maceration on the anastomosis. At the same time, the fixed outer cover at the anal canal end can maintain a certain tension through the traction of the first and second water balloons, thereby reducing the tension at the anastomosis. In this way, the risk of anastomotic leakage is greatly reduced in a single surgery, allowing for low-level anastomosis without the need for a small enterostomy to drain feces, improving the patient's quality of life and reducing medical risks and costs.

[0011] 2、The first rotating block on the moving block is moved towards the second rotating block, at this time the top rod arranged between the first rotating block and the second rotating block will gradually be vertical, at this time the storage bag is gradually inclined under the pushing of the top rod and the second rotating block, so that the backflow of some stored excrement when the storage bag is placed flat can be avoided, unnecessary influence on the patient is caused;

[0012] 3、The excrement flows into the storage bag through the anal canal, the storage bag with air holes at the end of the anal canal can store excrement without affecting exhaust, the connecting belt is arranged at both ends of the storage bag, and the first binding belt and the second binding belt arranged at both ends of the connecting belt are wound on the thigh, so that part of the gravity of the storage bag is shared by the thigh of the patient, and tearing and pulling of the anus are prevented.
