Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a device and method for fixing stoma tubes after gastrointestinal surgery. Background Technology

[0002] The stoma fixation device after gastrointestinal surgery is a surgical instrument and an indispensable type of specialized surgical instrument in clinical nursing of gastrointestinal surgery. Its design and production strictly adhere to the aseptic standards, biocompatibility requirements, and clinical practicality principles of surgical instruments. Together with surgical instruments and nursing instruments, it constitutes the core instrument system for postoperative nursing care in gastrointestinal surgery, providing crucial support for postoperative patient rehabilitation. This device is designed for abdominal wall stoma scenarios, employing a flexible, conforming base with adjustable tubing clamps and elastic band structures. It can securely fix stoma drainage and nutrition tubing, preventing slippage, twisting, and traction damage, reducing the risk of skin irritation and leakage around the stoma, adapting to patient positioning and movement, improving postoperative nursing safety and wearing comfort, and is easy to operate and maintain daily. As a highly targeted surgical instrument, it differs from conventional surgical instruments, focusing more on the stability, comfort, and convenience of long-term postoperative care. It can effectively compensate for the shortcomings of traditional tube fixation methods (such as tape fixation), such as easy loosening, easy skin damage, and poor adaptability. It meets the professional and meticulous needs of stoma care after gastrointestinal surgery and is an important surgical nursing instrument for improving the quality of stoma care and reducing the incidence of postoperative complications.

[0003] The prior art publication number CN106236209A provides an interventional percutaneous gastrointestinal fistula system. This technology has a simple structure and simplified operation steps, making percutaneous gastrostomy simpler and faster, and the technology is easier to master. At the same time, the indwelling fistula tube has an anti-reflux structure, which can directly inject food, and can also insert other gastric or intestinal feeding tubes through this fistula tube, which is convenient for management and replacement.

[0004] Existing technology fixes the fistula by using an external fixation cap and an external fixation seat in a fixed fistula assembly. After the outer movable fistula deforms, the external fixation seat is placed on the inner hollow fistula and presses against the push end of the outer movable fistula. The external fixation cap is then placed on the inner hollow fistula and screwed tightly onto the external fixation seat to fix the fistula. However, when inserting the tube through the stoma, manual insertion is required. Due to the instability of the force applied by the hand, sudden or excessive force can easily occur, causing the tube to suddenly surge forward and causing impact damage to the fragile stoma tissue, aggravating the patient's pain and postoperative discomfort. Therefore, we propose a device and method for fixing stoma tubes after gastrointestinal surgery. Summary of the Invention

[0015] A method for using a postoperative stoma tube fixation device in gastrointestinal surgery includes the following steps: S1. After performing a stoma following gastrointestinal surgery, the sterilized device is removed, the tube guide sleeve is aligned with the stoma, and then medical tape is applied around the stoma. Velcro is then used to further secure the device around the patient's abdomen. S2. Then align one end of the insertion tube with the pipe guide sleeve and insert a portion of it. At this time, by rotating the adjustment cover, the adjustment cover moves upward, and the U-shaped rod connected to the transmission block moves upward through the annular groove. Then the U-shaped rod will slide in the guide groove, thereby pushing the slide block connected to the adjustment plate to move, so that the contact wheel on the slide block contacts and clamps the insertion tube. S3. Then, by rotating the rotating sleeve, the rotating sleeve can drive the transmission wheel to rotate through the ring rack, so that the transmission wheel can drive the universal joint connected to the rotating shaft to rotate, and then the universal joint can drive the worm on the transmission rod to rotate, so that the worm can drive the contact wheel connected to the worm wheel to rotate, so that the contact wheel can push the tube to be inserted into the stoma, replacing manual insertion. S4. While the transmission wheel rotates, it can drive the rotating ring connected by the ring rack to rotate. At this time, the ring bevel rack on the rotating ring can drive multiple meshing bevel gears to rotate, so that the bevel gears drive the drain wheel to rotate, thereby continuously discharging the medical lubricant in the storage chamber through the drain port. Then, the rotating ring uses bristles to evenly apply the medical lubricant to the surface of the cannula to achieve automatic lubrication. S5. Then, when it is necessary to treat the blood seepage around the stoma after intubation, push the two levers to move the locking rod out of the locking hole and push the transparent cap up until the transparent cap moves to the outside of the adjustment cap and is locked in the rubber protrusion. Then place the two arc-shaped tourniquets in the fixing ring, then retract the two levers and push the transparent cap down so that the transparent cap presses on the arc-shaped tourniquet to prevent it from shifting. At the same time, align the locking rod with the locking hole and release the levers so that the spring drives the locking rod to insert into the locking hole for limiting. The skin condition and seepage around the stoma can be observed through the transparent cap.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. As a specialized surgical instrument for gastrointestinal surgery, this invention incorporates multiple push-and-clamp components within the guide sleeve, strictly adhering to the core requirements of sterility, precision, and safety in surgical instruments. Rotating the outer sleeve of the guide sleeve drives the contact wheels on the push-and-clamp components to rotate, thus replacing manual operation and achieving stable, uniform-speed tube insertion. This meets the standardized requirements of surgical intubation procedures. Furthermore, the adjusting cap ensures the contact wheels clamp and fix the tube after insertion. This effectively solves the problems of uneven force, potential damage to the stoma mucosa, and insufficient standardization in traditional manual intubation, a common surgical procedure. It also integrates pushing and fixing, simplifying surgical nursing procedures for medical staff, improving intubation precision and stability, and enhancing tube fixation reliability. This effectively prevents tube slippage, twisting, and traction damage, aligning with the trend towards convenient and safe surgical instruments. It significantly improves the safety and efficiency of this surgical instrument, providing more professional and reliable instrument support for stoma intubation care in gastrointestinal surgery. 2. By setting a lubrication component inside the tube guide sleeve, the medical lubricant in the reservoir can be automatically discharged during the process of pushing the cannula by the push tube clamping component. The bristles on the rotating ring can achieve uniform automatic lubrication of the outer wall of the cannula, which can effectively reduce the frictional resistance between the cannula and the stoma mucosa, avoid mucosal scratches, pain and discomfort and tissue damage during the pushing process. At the same time, there is no need for manual application of additional lubricant, simplifying the operation steps, improving the smoothness and safety of cannula insertion, and making it more conducive to post-stomach recovery and nursing operations. 3. By setting a transparent pressure cap, the condition of the skin around the stoma can be observed in real time during intubation, which facilitates precise operation and timely adjustment by medical staff. In case of bleeding after surgery, the arc-shaped tourniquet can be conveniently fixed around the stoma to achieve rapid hemostasis and ensure safe postoperative recovery. At the same time, the detachable transparent pressure cap design allows the arc-shaped tourniquet to be replaced individually, which not only ensures the overall sterility and practicality of the device, but also reduces nursing operation costs and the risk of postoperative complications for patients, further improving the convenience, safety and comfort of postoperative care.

[0036] A method for using a postoperative stoma tube fixation device in gastrointestinal surgery includes the following steps: S1. After the stoma is created following gastrointestinal surgery, as a prerequisite for the use of surgical instruments, the device that has been strictly disinfected and sterilized and meets the sterile standards for surgical instruments must be removed to avoid sterile contamination affecting stoma healing. Then, the tube guide sleeve 3 is aligned with the stoma, and then the medical tape 101 is attached around the stoma. The surgical instrument is further fixed around the patient's abdomen using Velcro tape 102. During the fixation process, both stability and comfort must be taken into account, in accordance with the requirements for the use of surgical nursing instruments to adapt to the patient's body position and movement. S2. Then, align one end of the cannula with the guide sleeve 3 and insert it partially. At this time, rotate the adjusting cover 5 to move the adjusting cover 5 upward. The U-shaped rod 503 connected to the transmission block 502 will follow the upward movement through the annular groove 501. Then, the U-shaped rod 503 will slide in the guide groove 403, thereby pushing the slide block 401 connected to the adjusting plate 402 to move. This will cause the contact wheel 404 on the slide block 401 to contact and clamp the cannula, ensuring that the clamping force is moderate. This ensures that the cannula is stable and avoids damage to the cannula and stoma mucosa, meeting the core requirements of precise and safe use of surgical instruments. S3. Then, by rotating the rotating sleeve 6, the rotating sleeve 6 can drive the transmission wheel 410 to rotate through the ring rack 602, so that the transmission wheel 410 can drive the universal joint 408 connected to the rotating shaft 409 to rotate, and then the universal joint 408 can drive the worm 406 on the transmission rod 407 to rotate, so that the worm 406 can drive the contact wheel 404 connected to the worm wheel 405 to rotate, so that the contact wheel 404 can push the tube to be inserted into the stoma, replacing manual hand insertion; S4. When the transmission wheel 410 rotates, it can drive the rotating ring 701 connected to the ring rack 702 to rotate. At this time, the ring bevel rack 704 on the rotating ring 701 can drive the meshing multiple bevel gears 705 to rotate, so that the bevel gears 705 drive the drain wheel 706 to rotate. At this time, the medical lubricant in the reservoir 301 will enter the drain port 302 under the action of gravity and fall between the blades of the drain wheel 706 used to close the drain port 302. When the drain wheel 706 rotates, the lubricant that has entered between the blades will rotate downward. The lubricant will fall automatically under its own weight. Then, the rotating ring 701 will evenly apply the medical lubricant to the surface of the cannula through the brush 703 to achieve automatic lubrication. S5. Then, when it is necessary to treat the blood seepage around the stoma after intubation, push the two levers 203 so that the levers 203 drive the locking rod 201 out of the locking hole 104 and push the transparent cap 2 up until the transparent cap 2 moves to the outside of the adjusting cover 5 and is locked in the rubber protrusion. Then place the two arc-shaped tourniquets 103 in the fixing ring 1, then retract the two levers 203 and push the transparent cap 2 down so that the transparent cap 2 presses on the arc-shaped tourniquets 103 to prevent them from shifting. At the same time, align the locking rod 201 with the locking hole 104 and release the levers 203 so that the spring 202 drives the locking rod 201 to be inserted into the locking hole 104 for limiting. The skin condition and seepage around the stoma can be observed through the transparent cap 2.
