Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a flushing device. Background Art
[0002] During choledochal endoscopic lithotripsy, doctors can use the choledochal endoscopic perfusion system to inject saline into the bile duct. The liquid environment in the bile duct can be optimized, which can help doctors more accurately observe the stones in the bile duct and perform corresponding stone removal operations. However, a small portion of the saline injected into the bile duct enters the intestine, and most of it flows out from the abdominal wall incision. The flushing fluid flows around, soaking the surgical operating surface and the patient's clothes, which not only affects the surgical operation but also makes the patient uncomfortable. In the prior art, a leak-proof plug is usually provided on the outer wall of the endoscope tube to solve the problem of flushing fluid flowing around.
[0003] However, in actual use of the above-mentioned device, since the leak-proof plug is located on the outer wall of the endoscope tube, it will move with the endoscope tube in the bile duct. During the process of choledochal endoscopic stone removal, if the leak-proof plug is not completely sealed or moves and becomes loose, it may cause leakage of saline, further affecting the surgical operation and the clarity of the field of vision. In view of this, we proposed a flushing device. Utility Model Content

[0013] Preferably, the airbag and the limiting arc plate are made of a silicone soft cover, so that the airbag and the limiting arc plate can fit the opening of the bile duct to prevent saline from overflowing through the opening, and an air chamber is provided in the limiting arc plate.
[0014] Compared with the prior art, the utility model provides a flushing device with the following beneficial effects:
[0015] 1. The flushing device is provided with a water inlet pipe, a sleeve, a water outlet, a guide plate, a liquid outlet, a water outlet pipe, an air bag, a saddle, an air filling tube and a limiting arc plate. The saddle is located at the opening of the bile duct. The air bag is inflated through the air filling tube so that the outer wall of the air bag fits with the opening. The two ends of the air bag are higher, so that the air bag is just stuck at the opening of the bile duct. The limiting arc plate fits with the inner wall of the bile duct to prevent the air bag from accidentally detaching. When the amount of normal saline is large, the normal saline flows in the opposite direction to the air bag and the surrounding of the connector. Since the limiting arc plate and the air bag form an arc-shaped groove area, the normal saline cannot flow in through the gap between the air bag and the bile duct, but will be discharged from the patient's body through the liquid outlet and the water outlet pipe, thereby improving the blocking effect of the air bag.
[0016] 2. The flushing device is provided with an inflatable soft sleeve, and air is inflated into the airbag to inflate the inflatable soft sleeve, and the limiting arc plate is lifted up to increase the abutment force, thereby ensuring that the connection between the limiting arc plate and the inner wall of the bile duct is firm and reliable. This helps to prevent the flushing device from accidentally detaching or shifting during operation and maintain the stability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

The airbag 11 is fixedly connected to the gas filling tube 13. The outer wall of the airbag 11 is sleeved with a limiting arc plate 14. The material of the airbag 11 and the limiting arc plate 14 is a silicone soft sleeve, so that the airbag 11 and the limiting arc plate 14 can fit with the opening of the bile duct to prevent the normal saline from overflowing through the opening. An air chamber is provided in the limiting arc plate 14. The outer wall of the airbag 11 is fixedly connected with an inflatable soft sleeve 15. The inflatable soft sleeve 15 is arranged on the inner wall of the limiting arc plate 14. The inflatable soft sleeve 15 is connected to the inside of the airbag 11. Inflating the airbag 11 can inflate the inflatable soft sleeve 15 and lift up the limiting arc plate 14.
[0024] Insert the endoscope tube 2 into the bile duct, with the saddle 12 located at the opening of the bile duct. Inflate the air bag 11 through the air filling tube 13, so that the outer wall of the air bag 11 fits with the opening. The two ends of the air bag 11 are higher, so that the air bag 11 is just stuck at the opening of the bile duct. The limiting arc plate 14 fits with the inner wall of the bile duct to prevent the air bag 11 from accidentally detaching. Then, inject physiological saline into the bile duct through the water inlet pipe 5 and the cannula 6. The physiological saline passes through the liquid outlet 9 and, under the guidance of the guide plate 8, the liquid ring in front of the endoscope tube 2 is The environment is optimized to provide doctors with a better field of vision, so that doctors can more clearly identify and locate stones for effective stone removal treatment. If the amount of normal saline is large, the normal saline flows back to the airbag 11 and the surrounding of the connector 1. Since the limiting arc plate 14 and the airbag 11 form an arc-shaped groove area, the normal saline cannot flow into the gap between the airbag 11 and the bile duct, but will be discharged from the patient's body through the liquid outlet 9 and the outlet pipe 10, thereby improving the blocking effect of the airbag 11.
[0025] In addition, in order to further improve the stability of the connection between the limiting arc plate 14 and the inner wall of the bile duct, the outer wall of the airbag 11 is fixedly connected with an inflatable soft sleeve 15, and the inflatable soft sleeve 15 is arranged on the inner wall of the limiting arc plate 14. The inflatable soft sleeve 15 is connected to the interior of the airbag 11. Inflating the airbag 11 can inflate the inflatable soft sleeve 15 and lift up the limiting arc plate 14, increase the abutment force, and ensure that the connection between the limiting arc plate 14 and the inner wall of the bile duct is firm and reliable. This helps to prevent the flushing device from accidentally detaching or shifting during operation and maintain the stability of the device.
[0026] In the utility model, when in use, the endoscope tube 2 is inserted into the bile duct, the saddle 12 is located at the opening of the bile duct, and air is inflated into the airbag 11 through the air filling tube 13, so that the outer wall of the airbag 11 fits with the opening. The two ends of the airbag 11 are higher, so that the airbag 11 is just stuck at the opening of the bile duct. The limiting arc plate 14 fits with the inner wall of the bile duct to prevent the airbag 11 from accidentally detaching. Then, physiological saline is injected into the bile duct through the water inlet pipe 5 and the sleeve 6. The physiological saline passes through the liquid outlet 9 and is guided by the guide plate 8 to optimize the liquid environment in front of the endoscope tube 2, providing a better field of view for the doctor, so that the doctor can more clearly identify and locate the stone for further treatment. Effective stone removal treatment, if the amount of normal saline is large, the normal saline flows back to the air bag 11 and the surrounding of the connector 1, because the limiting arc plate 14 and the air bag 11 form an arc-shaped groove area, the normal saline cannot flow in through the gap between the air bag 11 and the bile duct, but will be discharged from the patient's body through the liquid outlet 9 and the water outlet pipe 10. Furthermore, inflating the air bag 11 can inflate the inflatable soft sleeve 15 and lift the limiting arc plate 14 to increase the abutment force, ensuring that the connection between the limiting arc plate 14 and the inner wall of the bile duct is firm and reliable, which helps to prevent the flushing device from accidentally detaching or shifting during operation and maintain the stability of the device.
