Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a water exchange device for digestive endoscopy. Background Technology

[0002] Digestive endoscopy is a common and important endoscopic technique, primarily used for the diagnosis and treatment of digestive tract diseases. A common surgical method is Under-Water Endoscopic Submucosal Dissection (UESD). UESD is a minimally invasive surgical method for treating early-stage gastrointestinal cancers via digestive endoscopy. Unlike traditional ESD, UESD involves filling the lesion area with saline solution before performing the procedure underwater. The advantages of underwater ESD include: 1. The lesion is magnified underwater due to optical zoom, making observation easier; 2. The cooling effect of water helps reduce thermal damage to surrounding tissues during resection, further preventing complications; 3. The buoyancy of the water keeps the resected layer (submucosal layer) under tension, facilitating resection; 4. Continuous water injection utilizes the impact of the water flow to open the cutting surface, further aiding resection.

[0003] Currently, during UESD treatment, water is injected through the water injection port at the end of the endoscope via a water pump (controlled by a foot switch) (generally 500-1000ml), so that the lesion area is underwater, and then ESD surgery is performed.

[0004] The existing technology also has the following drawbacks:

[0005] 1. During the resection process, bleeding will make the fluid cloudy and gradually affect the field of vision.

[0006] 2. Suctioning turbid water through the end-lens suction hole will severely interfere with the field of view, making it impossible to perform water injection and resection operations simultaneously.

[0007] 3. During the resection procedure, the suction tube attached to the endoscope cannot be used for simultaneous water injection and suction, which significantly prolongs the operation time and increases the surgical risk.

[0008] Therefore, it is necessary to provide a water exchange device for digestive endoscopy to solve the above-mentioned technical problems. Utility Model Content

[0009] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water exchange device for digestive endoscopy.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: a water exchange device for digestive endoscopy, comprising an endoscope, a water storage bottle, a suction bottle, and a water pump. A partition is fixedly connected to the middle of the inner cavity of the water storage bottle, dividing the water storage bottle into a turbid water bottle and a clean water bottle. A suction tube is fixedly connected to the top of the turbid water bottle, and two rubber rings are fixedly connected to the other end of the suction tube. A side hole is opened at the end of the suction tube away from the turbid water bottle and between the two rubber rings. A screw cap is threadedly connected to the top of the clean water bottle, and a water supply pipe is fixedly installed through the top of the screw cap. A water delivery pipe is fixedly connected to the outlet of the water pump. A bottle cap is threadedly connected to the top of the suction bottle, and a suction tube one and a suction tube two are fixedly connected to the top of the bottle cap through a three-way pipe. An adjustable switch for controlling the suction speed is provided on the suction tube one. A suction hose is also fixedly connected to the top of the bottle cap.

[0011] As a further description of the above technical solution: the rubber ring is used to fix the suction tubing to the tip of the endoscope.

[0012] As a further description of the above technical solution: the end of the water supply pipe away from the clean water bottle is fixedly connected to the water inlet of the water pump, and when the water pump is turned on, clean water is drawn from the clean water bottle through the water supply pipe.

[0013] As a further description of the above technical solution: the water supply pipe extends from one end inside the clean water bottle to a position near the bottom of the clean water bottle, so that the water supply pipe can draw clean water from the bottom of the clean water bottle.

[0014] As a further description of the above technical solution: the endoscope has a water injection hole and a suction hole at its head end, and an endoscope water injection end and an endoscope suction end at its tail end. The endoscope also has an internal water supply pipe and an internal suction pipe. The internal water supply pipe and water injection hole work together to inject water into the patient's digestive tract through the water supply pipe and water delivery pipe when the water pump is started. The suction hole and internal suction pipe allow turbid water in the digestive tract to be drawn into the suction bottle. The endoscope's operating handle has a suction button to control the opening and closing of the internal suction pipe. When the internal suction pipe is open, the negative pressure inside the suction bottle causes the suction hole to draw turbid water from the digestive tract into the suction bottle through the internal suction pipe. However, if there is a large amount of turbid water in the suction bottle, medical personnel can unscrew the cap to detach it from the suction gas cylinder and pour out the collected turbid water.

[0015] As a further description of the above technical solution: the end of the water supply pipe away from the water pump is connected to the endoscope water injection end at the end of the endoscope, so that the water supply pipe is connected to the built-in water supply pipe inside the endoscope through the endoscope water injection end.

[0016] As a further description of the above technical solution: one end of the suction tube away from the bottle cap is fixedly connected to the bottom of the turbid water bottle, so as to draw the turbid water in the turbid water bottle into the suction bottle.

[0017] As a further description of the above technical solution: the end of the second suction tube away from the bottle cap is connected to the endoscope suction end at the end of the endoscope, so that the second suction tube is connected to the built-in suction tube inside the endoscope through the endoscope suction end.

[0018] This utility model has the following beneficial effects:

[0019] 1. Compared with existing technologies, this digestive endoscopy water exchange device can exchange clean and turbid water, ensuring a clear field of vision.

[0020] Compared with existing technologies, this digestive endoscopy water exchange device adds an external suction tube to the endoscope and uses the side hole on the suction tube for suction. It does not interfere with the surgical field of view during suction and can perform water injection and resection operations simultaneously.

[0021] Compared with existing technologies, this digestive endoscopy water exchange device is designed so that the suction of the external suction tube is provided by a water pump (controlled by an external foot switch), which enables simultaneous suction during water injection, shortens the operation time, and prevents turbid water and clean water from coming into direct contact, which will be discharged into the suction bottle through the pipeline.

[0029] Reference Figure 1-4 This utility model provides a water exchange device for digestive endoscopy surgery: including an endoscope 1, a water storage bottle 2, a suction bottle 3, and a water pump 4. The water pump 4 is electrically connected to an external foot switch (not shown in the figure), which is used to control the start and stop of the water pump 4. A partition 5 is fixedly connected to the middle of the inner cavity of the water storage bottle 2, dividing the water storage bottle 2 into a turbid water bottle 6 and a clean water bottle 7. The top of the turbid water bottle 6 is fixedly connected to a suction tube 8, and the other end of the suction tube 8 is fixedly connected to two rubber rings 9. The rubber rings 9 are used to fix the suction tube 8 to the head end of the endoscope 1. A side hole 1 is opened at the end of the suction tube 8 away from the turbid water bottle 6 and between the two rubber rings 9. 0. The top of the clean water bottle 7 is threadedly connected to a screw cap 11. A water supply pipe 12 is fixedly installed through the top of the screw cap 11. The end of the water supply pipe 12 away from the clean water bottle 7 is fixedly connected to the water inlet of the water pump 4. The end of the water supply pipe 12 located inside the clean water bottle 7 extends to a position near the bottom of the clean water bottle 7. The water outlet of the water pump 4 is fixedly connected to a water delivery pipe 13. The top of the suction bottle 3 is threadedly connected to a bottle cap 14. The top of the bottle cap 14 is fixedly connected to a first suction pipe 15 and a second suction pipe 16 through a three-way pipe. An adjustable switch 17 for controlling the suction speed is provided on the first suction pipe 15. The top of the bottle cap 14 is also fixedly connected to a suction hose 18.

[0030] The endoscope 1 has a water injection hole and a suction hole at its head end, and an endoscope water injection end 19 and an endoscope suction end 20 at its tail end. The endoscope 1 also has an internal water supply pipe and an internal suction pipe. The endoscope 1 has a suction button on its operating handle, which is used to control the opening and closing of the internal suction pipe. The water injection hole, suction hole, internal water supply pipe, internal suction pipe, operating handle, and suction button are not shown in the figure. The end of the water supply pipe 13 away from the water pump 4 is connected to the endoscope water injection end 19 at the tail end of the endoscope 1. The end of the first suction pipe 15 away from the bottle cap 14 is fixedly connected to the turbid water bottle 6 near the bottom. The end of the second suction pipe 16 away from the bottle cap 14 is connected to the endoscope suction end 20 at the tail end of the endoscope 1.

[0031] Working principle: First, medical staff pour an appropriate amount of clean water (physiological saline) into the clean water bottle 7 for later use. During the operation, the endoscope 1 tip is inserted into the patient's digestive tract. At the same time, the suction tube 8, which is fixed and tightened on the endoscope 1 tip by the rubber ring 9, is also inserted into the patient's digestive tract.

[0032] Then, the water pump 4 is controlled by an external foot switch (not shown in the figure) to transport the clean water in the clean water bottle 7 to the endoscope water injection end 19 at the end of the endoscope 1 through the water supply pipe 12 and the water delivery pipe 13. Then, the water is injected into the patient's digestive tract through the built-in water supply pipe inside the endoscope 1 and the water outlet at the end of the endoscope 1.

[0033] After the clean water in the clean water bottle 7 is drawn out, a negative pressure is formed inside it and conducted to the turbid water bottle 6. Then, the turbid water in the patient's digestive tract is drawn into the turbid water bottle 6 through the side hole 10 via the suction tube 8. The suction force of the suction tube 8 fixedly connected to the outside of the endoscope 1 is provided by the water pump 4 (the water pump 4 is started and stopped by an external foot switch), so that suction can be performed simultaneously when water is injected, shortening the operation time. The turbid water and the clean water do not come into direct contact and will pass through the tube suction bottle 3.

[0034] The turbid water in the turbid water bottle 6 is discharged into the suction bottle 3 through the suction tube 15, and the suction speed of the suction tube 15 can be controlled by the adjustable switch 17; through the combined use of the suction tube 2 16, the internal suction tube and the suction hole, the turbid water in the patient's digestive tract can also be suctioned into the suction bottle 3 (this process can be controlled by the suction button on the endoscope 1 operating handle, which is used to control the opening and closing of the internal suction tube).

[0035] The suction tube 18 on the suction bottle 3 is connected to the suction hole on the operating room wall to provide continuous suction.
