Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a C-arm machine-assisted placement of a nasoduodenal tube during minimally invasive esophageal cancer radical resection. Background Art

[0002] Esophageal cancer is a malignant tumor of the digestive tract that originates in the esophageal mucosal epithelium. my country has the highest incidence of esophageal cancer worldwide, primarily squamous cell carcinoma, which accounts for approximately 95.5%. The 2019 Annual Cancer Registry Report shows an incidence rate of 17.87 per 100,000 and a mortality rate of 13.68 per 100,000, ranking sixth and fourth among malignant tumors, respectively, accounting for over half of all esophageal cancer cases and deaths worldwide. Treatment of esophageal cancer has a history of over 120 years. Currently, the treatment approach for esophageal cancer in major hospitals is primarily surgery, supplemented by a comprehensive approach including radiotherapy and chemotherapy. Despite continuous advances in diagnostic and treatment technologies and surgical procedures, the five-year survival rate for esophageal cancer remains low, at approximately 15%-34%. To optimize patient outcomes, in addition to emphasizing regular screening and early detection among high-risk populations, improvements in clinical diagnostic and treatment methods are urgently needed.

[0003] Traditional open surgery, often referred to as Ivor-Lewis radical esophagectomy, has seen increasing use of minimally invasive thoracoscopic surgery (MIT-VAS) with the continuous advancement of laparoscopic surgery equipment and personnel. Recent studies have demonstrated that minimally invasive approaches, including robotic approaches, are feasible and safe for patients with esophageal cancer. Despite the increased surgical difficulty, these approaches offer comparable improvements in postoperative complications, particularly pulmonary complications such as pneumonia and mucus plugging that can cause atelectasis, compared with open surgery. This translates to significantly shorter hospital stays. ICU readmission and reoperation rates after MIE / RAMIE have decreased, though not significantly. Furthermore, minimally invasive approaches do not compromise the aggressiveness of primary tumor resection and lymph node clearance.

[0004] The clinical application of intravenous nutrition in the 1950s solved the problem of perioperative oral feeding difficulties for patients with esophageal cancer, thereby significantly reducing the incidence of postoperative complications caused by malnutrition. It played a vital role in the treatment of esophageal cancer and gradually became the standard method of perioperative nutritional therapy for patients with esophageal cancer. However, long-term parenteral nutrition causes damage to the function and structure of the patient's intestinal mucosa, weakens the intestinal barrier function, causes intestinal toxins and bacterial translocation, and even intestinal failure. Enteral nutrition is a nutrient intake method that conforms to normal physiological pathways and is considered the preferred route of surgical nutrition. In thoracic surgery, enteral nutrition therapy for esophageal cancer surgery is routinely performed with the insertion of a nasoduodenal tube.

[0005] Nowadays, when using duodenal tubes, during the insertion and rotation process, the shaking caused by medical staff or patients may cause the nutrient solution inlet tube to touch the nasal cavity, causing discomfort to the patient, or the shaking may cause excessive force during intubation, resulting in internal nasal bleeding, leading to blind insertion in the postoperative ward, causing patient discomfort and complications such as bleeding, thereby causing harm to the patient. In addition, during the process of removing the guide wire, the nutrient solution inlet tube will be involved, making it impossible for medical staff to effectively remove the guide wire. At the same time, the nutrient solution inlet tube may move during use, thereby reducing the effectiveness and success rate of the nasal duodenal tube. Utility Model Content

[0006] In view of the above-mentioned defects or deficiencies in the prior art, the present application aims to provide a C-arm-assisted insertion of a nasoduodenal tube during minimally invasive esophageal cancer radical resection, including a nutrient solution inlet tube, a guide wire is provided inside the nutrient solution inlet tube, the guide wire enters the nutrient solution inlet tube through the nutrient solution inlet at the lower part of the nutrient solution inlet tube, a nutrient solution outlet connected to the nutrient solution inlet tube is provided at the upper part of the nutrient solution inlet, a rotating ring is provided on the outside of the nutrient solution inlet tube, the inner diameter of the rotating ring is larger than the diameter of the nutrient solution inlet tube, a first airbag is provided on the right side of the rotating ring, a second airbag is provided on the left side of the first airbag, the second airbag is connected to the first airbag through a side connecting tube, the first airbag and the second airbag are connected to the inflation valve through the connecting tube, and an exhaust valve is provided on the right side of the upper part of the inflation valve.

[0007] Preferably, the guide wire is installed on the inner wall of the nutrient solution inlet tube, the lumen of the nutrient solution inlet tube is perfused with paraffin oil, and the surface of the guide wire is coated with paraffin oil, so that the guide wire can smoothly enter and exit the nutrient solution inlet tube without obvious resistance.

[0009] Preferably, the rotating ring is movably mounted on the outer wall of the nutrient solution inlet tube, the first airbag is mounted on one side of the rotating ring, and the second airbag is mounted on the other side of the rotating ring, and the position of the second airbag corresponds to that of the first airbag.

Beneficial effects

[0011] During the minimally invasive esophageal cancer radical resection, a C-arm machine assists in inserting a nasoduodenal tube. When inserting the guide wire into the nutrient solution inlet tube, paraffin oil is poured into the lumen of the nutrient solution inlet tube and the surface of the guide wire is fully coated with paraffin oil to make the guide wire and the nutrient solution inlet tube fit together. The guide wire is inserted and removed smoothly without obvious resistance, so that the nutrient solution inlet tube with the built-in guide wire is inserted into the nasal cavity. When the nutrient solution inlet tube is inserted, a rotating ring is provided on the outer wall of the nutrient solution inlet tube, and the first and second airbags are provided on the left and right ends of the rotating ring. At this time, the medical staff presses the inflated airbags. The air valve and the air inlet tube are pressed by the inflation valve to deliver the gas into the connecting tube, and the connecting tube delivers the gas into the first airbag and the second airbag. The first airbag and the second airbag are expanded by the entry of the gas. At this time, the first airbag and the second airbag are expanded and attached to the nasal cavity. At this time, the rotating ring is fixed in the nasal cavity by the expansion of the first airbag and the second airbag. At this time, the medical staff can deliver the nutrient solution inlet tube forward, so that the nutrient solution inlet tube is placed into the stomach through the nasal cavity to the vicinity of the pyloric orifice, and the nutrient solution inlet tube with a built-in guide wire is soft and elastic, and can be inserted under the guidance of the guide wire rotation. Into the duodenum, since the nutrient solution inlet tube is placed in the patient during general anesthesia, after the patient wakes up after the operation, the nutrient solution inlet tube is placed in the nasal cavity, and the nutrient solution inlet tube is easy to touch the nasal cavity, causing the patient to feel uncomfortable when waking up after the operation. Moreover, if the shaking caused by the patient after waking up causes the intubation tube to be vibrated, it is easy to cause damage to the patient, thereby effectively avoiding the intraoperative jejunostomy time and postoperative complications, avoiding harm to the patient, and achieving the goal of using the rotating ring and the first airbag and the second airbag in coordination, so that the nutrient solution inlet tube can be fixed while being introduced, and at the same time When the nutrient solution inlet tube is inserted below the descending duodenum, the guide wire is pulled out of the nutrient solution inlet tube. The nutrient solution inlet tube is positioned and fixed by the rotating ring and the first airbag and the second airbag, so that the nutrient solution inlet tube is not involved in the process of pulling out the guide wire, so that medical staff can pull out the guide wire more stably. At the same time, it also avoids the shaking of the nutrient solution inlet tube after the patient wakes up during use, which causes the intubation tube to be vibrated and cause damage to the patient, thereby effectively improving the success rate of inserting the nasoduodenal tube, thereby having the advantages of high success rate and simple operation.

[0019] See also Figure 1-3 During minimally invasive radical resection of esophageal cancer, a C-arm machine assists in the insertion of a nasoduodenal tube, including a nutrient solution inlet tube 1. A guide wire 101 is provided inside the nutrient solution inlet tube 1. The guide wire 101 enters the nutrient solution inlet tube 1 through the nutrient solution inlet 2 at the lower part of the nutrient solution inlet tube 1. A nutrient solution outlet 3 connected to the nutrient solution inlet tube 1 is provided on the upper part of the nutrient solution inlet 2. A rotating ring 4 is provided on the outside of the nutrient solution inlet tube 1. The inner diameter of the rotating ring 4 is larger than the diameter of the nutrient solution inlet tube 1. A first airbag 5 is provided on the right side of the rotating ring 4, and a second airbag 6 is provided on the left side of the first airbag 5. The second airbag 6 is connected to the first airbag 5 through a side connecting tube 7. The first airbag 5 and the second airbag 6 are connected to the inflation valve 9 through the connecting tube 7. An exhaust valve 10 is provided on the right side of the upper part of the inflation valve 9.

[0020] Among them, the guide wire 101 is installed on the inner wall of the nutrient solution inlet tube 1, paraffin oil is perfused into the lumen of the nutrient solution inlet tube 1, and the surface of the guide wire 101 is coated with paraffin oil. The guide wire 101 enters and exits the nutrient solution inlet tube 1 smoothly without obvious resistance.

[0021] The nutrient solution inlet 2 is opened below the nutrient solution input pipe 1 , and the nutrient solution outlet 3 is opened above the nutrient solution input pipe 1 .

[0022] Among them, the rotating ring 4 is movably installed on the outer wall of the nutrient solution inlet tube 1, the first airbag 5 is installed on one side of the rotating ring 4, and the second airbag 6 is installed on the other side of the rotating ring 4, and the position of the second airbag 6 corresponds to that of the first airbag 5.

[0023] Among them, the connecting tube 7 is connected to the sides of the first airbag 5 and the second airbag 6, the second airbag 6 is connected to the first airbag 5 through the connecting tube 7, the connecting tube 7 is fixedly connected to the inflation valve 9 arranged on the intake pipe 8, and the exhaust valve 10 is installed on one side above the inflation valve 9.

[0024] When in use, when inserting the guide wire 101 into the nutrient solution inlet tube 1, paraffin oil is poured into the lumen of the nutrient solution inlet tube 1 and the surface of the guide wire 101 is fully coated with paraffin oil to make the guide wire 101 suitable for the nutrient solution inlet tube 1. When inserting and removing the guide wire 101, it is smooth and there is no obvious resistance. Therefore, when the nutrient solution inlet tube 1 with the built-in guide wire 101 is inserted into the nasal cavity, when the nutrient solution inlet tube 1 is inserted, the rotating ring 4 provided on the outer wall of the nutrient solution inlet tube 1 and the first air bag 5 and the second air bag 6 provided on the left and right ends of the rotating ring 4 are passed, at this time, the medical staff presses the inflation valve 9, and the air inlet pipe 8 is compressed.

Moreover, if the shaking caused by the patient after waking up causes the intubation tube to be vibrated, it is easy to cause damage to the patient, thereby effectively avoiding the intraoperative jejunostomy time and postoperative complications, and avoiding harm to the patient. The coordinated use of the rotating ring 4 and the first airbag 5 and the second airbag 6 can achieve the goal of fixing the nutrient solution inlet tube 1 while introducing it, and at the same time, After the nutrient solution inlet tube 1 is inserted below the descending part of the duodenum, the guide wire 101 is pulled out from the nutrient solution inlet tube 1. The nutrient solution inlet tube 1 is positioned and fixed by the rotating ring 4 and the first air bag 5 and the second air bag 6 to avoid the nutrient solution inlet tube 1 being involved in the process of pulling out the guide wire 101, so that the medical staff can pull out the guide wire 101 more stably. At the same time, it also avoids the shaking of the nutrient solution inlet tube 1 after the patient wakes up during use, which causes the intubation tube to be vibrated and causes damage to the patient, thereby effectively improving the success rate of inserting the nasoduodenal tube, thereby having the advantages of high success rate and simple operation.
