Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and more specifically, to an irrigation and suction auxiliary device for endoscopes. Background Technology

[0002] With the development of modern medical technology, endoscopy, as an extension of the doctor's eyes and hands, can diagnose inflammation, ulcers, benign and malignant tumors in the digestive tract, as well as benign and malignant lesions of the liver, gallbladder, and pancreas, and even benign and malignant lesions of abdominal organs. Acute upper gastrointestinal bleeding is one of the most common acute and critical illnesses in gastroenterology, with peptic ulcer bleeding being the most frequent. For massive acute upper gastrointestinal bleeding, simple drug hemostasis is often ineffective, and interventional and surgical procedures can lead to many postoperative complications. Therefore, endoscopic hemostasis is the preferred treatment. However, during emergency endoscopic examination and treatment, large amounts of residual blood, blood clots, and food in the gastric cavity often obstruct the field of vision, making it difficult to locate the bleeding lesion and hindering effective endoscopic diagnosis and treatment. Therefore, during endoscopic examination, a negative pressure suction device is used to aspirate blood clots, fluid, and residue, and a water infusion device is used to flush the lesion. However, in order to quickly locate the bleeding lesion, it is often necessary to insert a suction tube, a flushing tube, and an endoscope into the patient's body at the same time. However, due to the large number of instruments inserted into the patient's body, the patient is prone to experiencing discomfort in the throat for a long time after the endoscopic examination and treatment are completed. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies that require multiple instruments to be inserted into the patient's body simultaneously during endoscopic examinations and treatments, causing discomfort. This invention provides an auxiliary device for rinsing and suctioning in endoscopy, which can facilitate suction and rinsing operations while reducing discomfort in the patient's throat and improving the patient's medical experience.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A flushing and suction auxiliary device for an endoscope is provided, comprising a suction tube and a flushing tube connected to the suction tube, wherein the flushing tube and the suction tube are not in communication with each other. A first end of the suction tube is a connection end for connecting to a negative pressure suction device, and a second end of the suction tube is a suction end for aspiration.

[0009] Preferably, the extension direction of the connecting pipe section is perpendicular to the extension direction of the flushing pipe.

[0010] Preferably, the extension direction of the connecting pipe segment is parallel to the extension direction of the second pipe segment.

[0011] Preferably, the second pipe section has multiple suction holes near the suction end, and these suction holes are not connected to the interlayer flow channel. The suction holes facilitate the control of the suction operation.

[0012] Preferably, the interlayer flow channel includes a confluence flow channel and a plurality of branch flow channels connected to and communicating with the confluence flow channel. The confluence flow channel is connected to the flushing pipe, and the branch flow channels are connected to the outside.

[0013] Preferably, the multiple branch channels are evenly distributed.

[0014] Preferably, the outer wall of the suction tube is connected to a connector for connection with an endoscope. This connector prevents displacement of the flushing and suction aid during diagnostic and treatment procedures.

[0015] Preferably, the connector is any one or more of cable ties, straps, and snap rings.

[0033] Example 1

[0034] like Figures 1 to 4 The illustration shows a first embodiment of an irrigating and suction auxiliary device for an endoscope according to the present invention. It includes a suction tube 100 and an irrigation tube 200 connected to the suction tube 100, wherein the suction tube 100 and the irrigation tube 200 are not connected to each other. The first end of the suction tube 100 is a connecting end for connecting to a negative pressure aspirator, and the second end of the suction tube 100 is a suction end for aspiration. An interlayer flow channel 300 is provided inside the tube wall of the suction tube 100, and the interlayer flow channel 300 is not connected to the suction tube 100. The first end of the interlayer flow channel 300 is connected to the irrigation tube 200, and the second end of the interlayer flow channel 300 is connected to the outside. The second end of the interlayer flow channel 300 is located at the second end of the suction tube 100.

[0035] The connection end of the suction tube 100 can be used to connect to a negative pressure suction device, and the suction end of the suction tube 100 can be used to aspirate blood clots, fluid accumulation, residues, etc. in the gastric cavity; the flushing tube 200 can be used to connect to a water injector, and the lesions in the gastric cavity can be flushed through the interlayer flow channel 300; the setting of the interlayer flow channel 300 within the tube wall of the suction tube 100, and the setting of the second end of the interlayer flow channel 300 at the second end of the suction tube 100, can reduce the number of instruments inserted into the patient's body while realizing convenient operation of suction and flushing, thereby reducing the patient's throat discomfort and improving the patient's medical experience.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, the suction tube 100 includes a first tube segment and a second tube segment 130 connected to and communicating with the first tube segment. The second tube segment 130 has a crescent-shaped cross-section, and its end is the suction end. The irrigation tube 200 is connected to the first tube segment. The crescent-shaped structure allows for the fitting of the endoscope 500, effectively reducing the overall cross-sectional area of ​​the instrument inserted into the patient's body and further alleviating discomfort in the patient's throat. The first tube segment includes a connecting tube segment 110 and a bent tube segment 120. The connecting tube segment 110, the bent tube segment 120, and the second tube segment 130 are sequentially connected and communicating with each other. The end of the connecting tube segment 110 is the connecting end. The irrigation tube 200 is connected to the connecting tube segment 110, but the irrigation tube 200 and the connecting tube segment 110 are not interconnected. The bent tube section 120 is designed so that the connecting tube section 110 and the second tube section 130 are not on the same vertical line. This ensures that when the second tube section 130 is in close contact with the endoscope 500, there is a certain distance between the connecting tube section 110 and the endoscope 500, which facilitates the connection of the connecting tube section 110 to the negative pressure suction device.

[0037] like Figure 1 and Figure 2 As shown, the extending direction of the connecting pipe section 110 is perpendicular to the extending direction of the flushing pipe 200. This perpendicular arrangement facilitates the connection between the flushing pipe 200 and the water injector. In this embodiment, the extending direction of the connecting pipe section 110 is parallel to the extending direction of the second pipe section 130.

[0038] like Figure 1 and Figure 4 As shown, the second pipe section 130 has multiple suction holes 131 on its wall near the suction end. The suction holes 131 are connected to the second pipe section 130, but are not connected to the interlayer flow channel 300. The arrangement of the suction holes 131 facilitates the control of the suction operation. Preferably, the suction holes 131 are arranged in a specific pattern in the second pipe section 130.

[0039] The working principle of the irrigation and suction auxiliary device for endoscopes in this embodiment is as follows:

[0040] The negative pressure aspirator is connected to the connecting tube section 110, and the flushing tube 200 is connected to the water injector, with the second tube section 130 tightly attached to the endoscope. When the endoscope and the flushing and aspiration auxiliary device are extended into the patient's stomach cavity, by activating the negative pressure aspirator, blood clots, fluid accumulation, residues, etc. in the stomach cavity can be aspirated sequentially through the suction port 131 and the suction tube 100. By activating the water injector, water can flow sequentially through the flushing tube 200 and the interlayer flow channel 300 to flush the lesion, making it easier to expose the lesion and allowing the doctor to better observe and diagnose the lesion through the endoscope.

[0041] Example 2

[0042] This embodiment is a second embodiment of the irrigation and suction auxiliary device for endoscopes according to the present invention. This embodiment is similar to the first embodiment, except that, as Figures 3 to 5 As shown, the interlayer flow channel 300 includes a confluence flow channel 310 and multiple branch flow channels 320 connected to and communicating with the confluence flow channel 310. The confluence flow channel 310 is connected to the flushing pipe 200, and the branch flow channels 320 are connected to the outside. The arrangement of multiple branch flow channels 320 can improve the flushing effect. Specifically, the second pipe section 130 includes a confluence pipe section and a branch pipe section. One end of the confluence pipe section is connected to the bend pipe section 120, and the other end of the confluence pipe section is connected to the branch pipe section. The confluence flow channel 310 is arranged in the connecting pipe section 110, the bend pipe section 120, and the confluence pipe section, while the branch flow channels 320 are arranged in the branch pipe section. The suction hole 131 is also provided at the branch pipe section.

[0043] In this embodiment, multiple branch channels 320 are evenly distributed. Specifically, when multiple suction holes 131 are arranged on the branch pipe section, there are gaps between adjacent columns of suction holes 131, and the branch channels 320 are arranged in these gaps, so that the branch channels 320 can be evenly distributed, and the end of the branch channel 320 that is connected to the outside can face the foremost tip of the endoscope, which is convenient for rapid rinsing.

[0044] The working principle of the irrigation and suction auxiliary device for endoscopes in this embodiment is as follows:

[0045] The negative pressure aspirator is connected to the connecting tube section 110, and the flushing tube 200 is connected to the water injector, with the second tube section 130 tightly attached to the endoscope. When the endoscope and the flushing and aspiration auxiliary device are extended into the patient's stomach cavity, by activating the negative pressure aspirator, blood clots, fluid accumulation, residues, etc. in the stomach cavity can be aspirated sequentially through the suction port 131 and the suction tube 100. By activating the water injector, water can flow out sequentially through the flushing tube 200, the confluence channel 310, and the branch channel 320, and can flush the lesion, making it easier to expose the lesion, so that the doctor can better observe and diagnose the lesion through the endoscope.

[0046] Example 3

[0047] This embodiment is the third embodiment of the irrigation and suction auxiliary device for endoscopes according to this utility model. This embodiment is similar to embodiment one or two, except that, as Figure 6 As shown, the outer wall of the suction tube 100 is connected to a connector 400 for connection with the endoscope 500. The connector 400 prevents displacement of the flushing and suction aid during diagnostic and treatment procedures. The connector 400 is located on the outer wall of the second tube segment 130. Specifically, the connector 400 is any one or more of a cable tie, strap, or locking ring.

[0048] The working principle of the irrigation and suction auxiliary device for endoscopes in this embodiment is as follows:

[0049] The negative pressure aspirator is connected to the connecting tube section 110, and the flushing tube 200 is connected to the water injector. The second tube section 130 is connected to the endoscope through the connector 400. When the endoscope and the flushing and aspiration auxiliary device are extended into the patient's stomach cavity, by activating the negative pressure aspirator, blood clots, fluid accumulation, residues, etc. in the stomach cavity can be aspirated sequentially through the suction port 131 and the suction tube 100. By activating the water injector, water can flow out sequentially through the flushing tube 200, the confluence channel 310, and the branch channel 320, and can flush the lesion, making it easier to expose the lesion, so that the doctor can better observe and diagnose the lesion through the endoscope.

[0050] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
