Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to an intraoperative intestinal contents collection device. Background Technology
[0002] Intestinal obstruction and necrosis is a common condition in general surgery, and its clinical treatment methods are becoming increasingly diverse. In recent years, partial bowel resection and anastomosis via laparoscopy or laparoscopy has been widely used in the treatment of intestinal obstruction and necrosis, as well as intestinal tumors, showing significant advantages, especially in the management of partial bowel necrosis. During this procedure, effective drainage of intestinal contents is necessary while removing the necrotic bowel segment and anastomosing the normal bowel.
[0003] Currently, negative pressure suction tubes are commonly used in clinical practice to collect intestinal contents. These tubes consist of a tubular structure connected to a negative pressure suction device. However, these devices pose risks of tube blockage and detachment during use. Furthermore, the presence of negative pressure can cause the suction tip to be drawn into the intestinal wall, leading to blockage and potential secondary damage. This necessitates stopping the procedure to remove the negative pressure, which can result in leakage of intestinal contents or further outflow from the suction tip. If leakage occurs during intestinal contents collection, the patient faces risks such as surgical site contamination, postoperative abdominal infection, and incision infection, thus prolonging postoperative recovery time and increasing the patient's treatment burden.
[0004] Therefore, the development and application of efficient and low-leakage intestinal contents collection devices are of vital clinical significance for improving surgical outcomes and shortening patient recovery periods. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an intraoperative intestinal contents collection device to achieve efficient and low-leakage intestinal contents collection.
[0006] The technical solution to achieve the purpose of this utility model is: An intraoperative intestinal contents collection device, comprising A collection catheter is used to connect to the fistula opening of the patient's intestinal stoma. The collection catheter is a tubular body with openings at the top and bottom, one end of which is a collection port and the other end is a connection port. Collection bag, which is used to hold intestinal contents; A drainage catheter is used to drain intestinal contents collected by a collection catheter into a collection bag. The drainage catheter is a telescopic tube, with one end connected to the connection port of the collection catheter and the other end connected to the collection bag.
[0007] Furthermore, the collection port of the collection catheter is funnel-shaped.
[0008] Furthermore, the telescopic tube is a flexible telescopic tube.
[0009] Preferably, the flexible telescopic tube is a flexible corrugated tube or a flexible threaded telescopic tube.
[0010] Furthermore, the diameter of the collection port of the collection catheter is 2.0-2.5cm, the diameter of the connection port is 1.5-2.0cm, and the length of the collection catheter is 2.5-3.5cm; the length of the drainage catheter is 1.5-2.5m, and the diameter is 3.0-5.0cm; the volume of the collection bag is 4.5-5.5L.
[0011] The core components of this invention include a collection catheter, a drainage catheter, and a collection bag. The collection port of the collection catheter is funnel-shaped with a large diameter to ensure a tight and anastomotic connection with the patient's intestinal stoma. The connection port is a small-diameter, cylindrical tube to ensure connection stability and smooth drainage. A drainage catheter is connected to the small-diameter connection port of the collection catheter. This drainage catheter is retractable and threaded, enabling convenient and flexible drainage over different distances, effectively reducing reflux and ensuring the safety and efficiency of the drainage process. Furthermore, a collection bag is connected to the distal end of the drainage catheter, specifically designed to receive and store the intestinal contents drained by the drainage catheter. The design of this device fully considers individual patient differences, ensuring that the device can be adapted to the specific circumstances of each patient.
[0012] The beneficial effects of this utility model are as follows: This novel intraoperative intestinal contents collection device is simple and quick to use. The collection port of the collection catheter is inserted into the artificial fistula opening in the patient's intestine. The intestinal contents are then manually pushed to the fistula opening. The contents enter the collection catheter through the collection port, flow through the drainage catheter, and finally enter a collection bag for storage, thus achieving efficient drainage of the target drainage area. This design eliminates negative pressure, significantly reducing the risk of secondary damage to the intestinal wall caused by existing suction drainage tubes, the risk of drainage leakage, and greatly reducing adverse events caused by drainage tube blockage or dislodgement, thereby comprehensively reducing the overall surgical risk. This device focuses on precise connection to the patient's intestinal fistula area, ensuring focused and efficient intraoperative procedures.
[0013] This collection device features a funnel-shaped collection conduit, a unique structure that significantly enhances the smoothness of the drainage process. This design allows for more efficient guidance and collection of liquids or gases, improving the overall efficiency and effectiveness of the drainage process. Furthermore, it is equipped with a retractable, corrugated, or threaded drainage conduit. This retractable feature allows the length of the conduit to be adjusted according to actual needs, accommodating drainage requirements at different depths and locations. The corrugated or threaded design ensures that leakage or slippage does not occur during drainage, further enhancing the stability and sealing of the conduit. Moreover, due to the corrugations or threads, the inner wall of the drainage conduit is not flat but undulates with the corrugations or threads, which to some extent prevents backflow, thus ensuring the safety and reliability of the drainage process.
