Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a special abdominal irrigation and drainage tube for pancreatic surgery. Background Technology

[0002] Pancreatic surgery is a high-risk, highly complex surgical procedure commonly used to treat pancreatic cancer, pancreatitis, and other diseases. However, postoperative complications (such as pancreatic fistula) are very common. Pancreatic fistula can lead to serious problems such as postoperative abdominal infection and bleeding, and is a major cause of patient death. Effective postoperative drainage and irrigation are crucial for preventing complications. Existing drainage tubes often suffer from poor irrigation effectiveness and inability to precisely control the irrigation rate. Therefore, this study aims to design a dedicated abdominal irrigation and drainage tube for pancreatic surgery. By embedding the irrigation tube and a speed control device, continuous irrigation, precise adjustment of the irrigation rate, and real-time monitoring of the drainage fluid can be achieved, effectively improving postoperative recovery and reducing the risk of infection and bleeding, thus possessing significant clinical value.

[0003] Pancreatic fistula is the most common and dangerous complication after pancreatic surgery. Poor drainage of the fistula after surgery easily leads to infection of the surgical area and intra-abdominal hemorrhage, making it the most common cause of postoperative bleeding and a leading cause of death in pancreatic surgery patients. The principles of prognosis and management of pancreatic fistula are early detection and early drainage, reducing the amylase concentration in the drainage fluid. However, effectively flushing and draining the fistula and adjusting the flushing rate in a timely manner remain challenges in pancreatic surgery. Currently available drainage tubes do not provide satisfactory flushing and drainage, and the flushing rate cannot be accurately controlled. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a special abdominal irrigation and drainage tube for pancreatic surgery, which aims to improve the problem that the irrigation and drainage effect of traditional drainage tubes is not good and the irrigation speed cannot be accurately controlled.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special abdominal irrigation and drainage tube for pancreatic surgery, comprising a drainage tube, an irrigation tube passing through the interior of the drainage tube, a head fixedly connected to one end of the irrigation tube, a sealing component provided at one end of the head for sealing the drainage tube and the irrigation tube, a nozzle fixedly connected to the other end of the head, an adjusting tube fixedly connected to one end of the nozzle, an external delivery tube fixedly connected inside the adjusting tube, and a delivery component provided on one side of the outer wall of the nozzle for delivering the required medication to the interior of the nozzle;

[0006] The sealing assembly includes a second elastic washer and a first elastic washer, both of which are disposed at one end of the end cap and are attached to the inner and outer sides of the drainage tube.

[0007] Furthermore, the delivery assembly includes a diverter pipe, one end of which is fixedly connected to the outer wall of the nozzle, and the other end of which is threadedly connected to a threaded cap.

[0008] Furthermore, a rotating rod is rotatably connected inside the regulating tube, a worm is fixedly connected to the outer wall of the rotating rod, a worm wheel is rotatably connected inside the regulating tube, the worm meshes with the worm wheel, a rotating shaft is fixedly connected inside the worm wheel, a baffle is fixedly connected to the lower side of the outer wall of the rotating shaft, and a sealing assembly is provided on the outer wall of the baffle for sealing between the baffle and the regulating tube.

[0009] Furthermore, the sealing assembly includes a sealing gasket, the inner wall of which is fixedly connected to the outer wall of the baffle, and two sealing bearings are fixedly connected to the outer wall of the rotating shaft, the sealing bearings being disposed on the upper and lower sides of the baffle.

[0010] Furthermore, the end of the end is disposed inside the drainage tube, and the end is used to drive the elastic gasket ring to be conveyed to the inside of the drainage tube.

[0011] Furthermore, the outer ring of the sealed bearing is fixedly connected inside the adjusting tube, and the sealed bearing is used to seal the space between the rotating shaft and the adjusting tube.

[0012] Furthermore, the outer wall of the worm is rotatably connected to the inside of the adjusting tube, and the worm is used to drive the worm wheel to rotate.

[0013] Furthermore, the outer wall of the rotating shaft is rotatably connected to the inside of the adjusting tube, and the rotating shaft is used to drive the baffle to rotate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, one end of the flushing tube is first passed through the pre-set through hole inside the drainage tube and pulled, thereby moving the end of the tube into the drainage tube. It is then sealed with elastic gasket one and elastic gasket two. Next, the cleaning fluid is delivered into the flushing tube for easy cleaning with the nozzle, regulating tube and external delivery tube. Finally, medication can be added to the cleaning fluid through the diversion tube and threaded cap. This achieves a highly efficient cleaning function, which can promptly drain contaminated fluid and metabolic products from the abdominal cavity, reduce the environment for bacterial growth, and thus significantly reduce the incidence of postoperative abdominal infection.

[0016] 2. In this utility model, the drive rod first drives the worm gear to rotate, and then the worm wheel and the rotating shaft drive the baffle to rotate to adjust the flow rate. In addition, it can also prevent the baffle from rotating due to the impact of the water flow. Finally, the sealing gasket and sealing bearing are used to facilitate sealing and prevent leakage. The flow rate can be precisely adjusted according to the patient's postoperative condition to flexibly adjust the speed of the irrigation solution, ensuring that the irrigation solution can effectively cover the surgical area and achieve a thorough cleaning effect.

[0027] Working principle: When a special abdominal irrigation and drainage tube for pancreatic surgery is needed, firstly, an opening is made inside the drainage tube 1. Then, one end of the irrigation tube 2 is inserted into the drainage tube 1. Next, one end of the irrigation tube 2 is clamped with forceps or other tools and pulled outward, allowing the irrigation tube 2 to pass through the interior of the drainage tube 1. Simultaneously, the other end of the irrigation tube 2 moves the nozzle 3 and end cap 6 to one side of the outer wall of the drainage tube 1. Then, the end cap 6 is pressed into the interior of the drainage tube 1, which simultaneously moves the elastic washer 7 into the interior of the drainage tube 1. The elastic washer 7 and elastic washer 8 at one end of the end 6 are respectively attached to the inner and outer sides of the drainage tube 1, thereby stably sealing the opening of the drainage tube 1. Then, liquid is delivered into the external delivery tube 13. At this time, the liquid is delivered into the flushing tube 2 through the regulating tube 9, the nozzle 3 and the end 6, which facilitates flushing. In addition, the threaded cap 5 can be rotated to cooperate with the internal thread to open and close the diversion tube 4, thereby facilitating the addition of medicine into the nozzle 3 and delivering it together with the liquid to achieve efficient cleaning.

[0028] Furthermore, the drive rotating rod 10 drives the worm 11 to rotate inside the regulating pipe 9. In conjunction with the meshing relationship between the worm 11 and the worm wheel 12, the worm wheel 12 drives the rotating shaft 14 to rotate with the rotation of the worm 11. This, in turn, drives the baffle 15 to rotate through the rotating shaft 14, thereby adjusting the gap between the baffle 15 and the regulating pipe 9 to regulate the flow rate. During this process, when the baffle 15 is fully closed, the sealing gasket 16 can seal the gap between the baffle 15 and the regulating pipe 9 to prevent leakage. At the same time, the upper and lower sealing bearings 17 can also seal the gap between the rotating shaft 14 and the regulating pipe 9.
