Description

Technical Field

[0001] This utility model relates to an endoscope connecting tube with water delivery function. Background Technology

[0002] In gastrointestinal endoscopy, rinsing of the digestive tract is sometimes necessary to obtain a better view and improve surgical efficiency. Some imported gastroscopes and colonoscopes are equipped with rinsing ports, and the water pump connecting tube can be directly screwed to the rinsing port. The rinsing solution is delivered to the endoscope through the rinsing port via the water pump and connecting tube. For example, Chinese utility model patent CN216257016U, entitled "A Water Pump Connecting Device for a Digestive Endoscope," discloses a water pump connecting device for a digestive endoscope, comprising: a connecting tube, including a first end and a second end; a saline connector, one end for connecting to saline solution, and the other end connected to the first end of the connecting tube; a flow rate tube, sleeved on the outer periphery of the connecting tube, with a portion of the connecting tube extending into and connected to the flow rate tube; a water pump pressure tube, sleeved on the outer periphery of the connecting tube located under the rolling groove of the water pump main unit; and an endoscope spiral connector, one end connected to the second end of the connecting tube, and the other end connected to the water delivery port of the endoscope. This type of connecting pipe can be used to transport cleaning fluid, but it is only suitable for equipment with rinsing ports, and its function is relatively simple.

[0003] Imported gastroscopes and colonoscopes equipped with the aforementioned irrigation ports are more expensive, costing tens of thousands of yuan more than those without such ports. Some gastroscopes and colonoscopes do not have these irrigation ports. For example, Chinese utility model patent CN218852743U, entitled "Endoscopic Biopsy Cap Anti-Spray Device," discloses an endoscopic biopsy cap anti-spray device, including a main body, a connecting and fixing mechanism, and a valve anti-spray mechanism. The connecting and fixing mechanism is provided on one outer wall of the main body, and a valve anti-spray mechanism is provided at one end of the connecting and fixing mechanism. The valve anti-spray mechanism includes a biopsy valve tube, a soft rubber cap, a silicone connecting rope, a soft rubber threaded inner plug, a soft rubber plug, and a back buckle. The front end of the biopsy valve tube is provided with a soft rubber cap, one side of which is connected to a silicone connecting rope. A soft rubber threaded inner plug is provided on one inner wall of the soft rubber cap, and a soft rubber plug is provided at one end of the soft rubber threaded inner plug. A back buckle is provided on one outer wall of the soft rubber cap. When this type of endoscope requires irrigation, the soft rubber cap is removed, and 50ml of normal saline is drawn up using a 50ml syringe and injected into the endoscope through the valve. This method requires nurses to manually assist the hospital in performing the procedure at any time, increasing the workload and making it difficult to control the irrigation volume.

[0004] Based on the above issues, the applicant conducted research, which led to this case. Utility Model Content

The first connector is connected to the water pump, and the second connector is inserted into the biopsy valve tube. The water pump is started to deliver the cleaning solution into the gastroscope and colonoscope for rinsing. In this way, the doctor can control the water pump by himself (for example, some water pumps are controlled by a foot switch), without the need for nurses to manually assist the doctor in rinsing the wound or mucosa under endoscopy, saving labor. This utility model adds a branch tube, which is used to connect a syringe. Special drugs such as norepinephrine in saline can be used for wound hemostasis; 50ml of normal saline with 1ml of simethicone can be used as an antifoaming agent to remove bubbles in the intestine (many bubbles are generated during gastrointestinal peristalsis, which can affect the endoscope's field of vision and obscure lesions), making the functions of this utility model more diversified.
