Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an endoscopic outer sheath tube. Background Art

[0002] An endoscope enters the stomach through the oral cavity or enters the body through other natural orifices for disease examination or treatment based on the principle of physical imaging. The endoscope can reliably solve the diagnosis of common tumors, especially the timely detection of early cancers, and can make a pathological diagnosis before surgery. Therefore, it is superior to other diagnostic methods. The most common digestive tract diseases are inflammation, ulcers, and tumors. Digestive endoscopy is the gold standard for the clinical diagnosis of most digestive tract diseases.

[0003] However, the following problems still exist in the prior art: 1. Currently, when treating many patients with digestive tract bleeding in emergency endoscopy, the existing endoscopic suction channels cannot meet the needs and are easily blocked by blood clots; 2. During endoscopy, large blood clots affect the endoscopic observation, making it inconvenient to treat the patients; 3. The existing devices have a slow cleaning efficiency for blood clots and need to be cleaned multiple times. Summary of the Invention

[0004] The main purpose of the present invention is to provide an endoscopic outer sheath tube, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] An endoscopic outer sheath tube includes a mounting rod. A mounting hole is opened in the middle of the right end of the mounting rod. An expansion tube is fixedly inserted and connected to the outer surface of the left part of the mounting rod. A first connecting hose is fixedly inserted and connected to the outer surface of the middle part of the mounting rod. A suction mechanism is fixedly inserted and connected to the outer surface of the upper right part of the first connecting hose. One end of the suction mechanism away from the first connecting hose is fixedly connected to a fixed tube. A connecting head is inserted and connected to the outer surface of the lower part of the fixed tube by a bearing. A material receiving mechanism is screwed and inserted into the middle of the lower end of the connecting head. An air injection mechanism is fixedly inserted and connected to the outer surface of the lower right part of the first connecting hose. The right end of the expansion tube is fixedly connected to the left end of the first connecting hose.

[0007] Preferably, the first connecting hose includes a first tube body. A connecting groove is opened in the middle of the left end of the first tube body. A first insertion groove is opened in the outer surface of the upper right part of the first tube body. A second insertion groove is opened in the outer surface of the lower right part of the first tube body. Both the second insertion groove and the first insertion groove communicate with the inside of the connecting groove. The first tube body is fixedly inserted and connected to the mounting rod.

[0008] Preferably, the expansion tube includes a connecting ring. In the middle of the left end of the connecting ring, a close-fitting tube is fixedly connected. At the right end of the connecting ring, an airbag is fixedly connected. The close-fitting tube is located inside the airbag. An expansion cavity is arranged between the close-fitting tube and the airbag. A third insertion groove is formed in the upper part of the left end of the connecting ring. The connecting ring and the mounting rod are fixedly inserted and connected together.

[0009] Preferably, the close-fitting tube and the mounting rod are fixedly inserted and connected together. The inside of the third insertion groove and the expansion cavity are in communication with each other. The expansion cavity and the connection groove are in communication with each other.

[0010] Preferably, the suction mechanism includes a duct. At the right end of the duct, a plug is fixedly connected. At the end of the duct away from the plug, a suction pipe is fixedly connected. At the lower end of the suction pipe, a second connecting hose is fixedly inserted and connected. The duct and the first insertion groove are fixedly inserted and connected together.

[0011] Preferably, the second connecting hose and the third insertion groove are fixedly penetrated and connected together. The second connecting hose and the connection groove are inserted and connected together.

[0012] Preferably, the air injection mechanism includes a fourth insertion pipe. At the right end of the fourth insertion pipe, a trachea is fixedly connected. At the end of the trachea away from the fourth insertion pipe, an air pump is fixedly connected. In the middle of the upper end of the air pump, a power supply is arranged. In the middle of the front end of the air pump, a controller is fixedly connected. The fourth insertion pipe and the second insertion groove are fixedly inserted and connected together.

[0013] Preferably, the material receiving mechanism includes a suction device. In the middle of the upper end of the suction device, a first insertion pipe is fixedly inserted and connected. In the middle of the upper end of the first insertion pipe, a perforation is formed. A second insertion pipe is inserted into the perforation. The second insertion pipe and the connection head are threadedly inserted and connected together.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, the mounting rod is sleeved on the outer surface of the inner lens through the mounting hole, and the mounting rod is made of a soft material. When the expansion tube is not in use, it is in a contracted state. When the inner lens enters the body, the inner lens will drive the mounting rod sleeved with it into the patient's body. The mounting rod will bring both the first connecting hose and the expansion tube into the patient's body, thus facilitating the cleaning of blood clots and avoiding the blockage of the endoscopic suction duct, which affects the diagnosis and treatment of the patient.

[0016] 2. By setting up an attracting mechanism and a material receiving mechanism, starting the attracting device, the second connecting hose sucks large blood clots into the second connecting hose, and the second connecting hose introduces them into the duct through a straw. The duct guides the large blood clots into the connector, and the connector introduces them into the attracting device, so that the large blood clots can be sucked out, exposing the specific conditions in the digestive tract clearly, facilitating endoscopic observation, diagnosis and treatment.

[0017] 3. By setting up an expansion tube and an air injection mechanism, pressing the power supply makes the air pump in an open state. Set the time, power, etc. on the controller, so as to inject air into the trachea. The trachea introduces the gas into the fourth insertion tube, the fourth insertion tube introduces the gas into the connection groove, and the connection groove introduces the gas into the expansion cavity, making the airbag expand. The airbag no longer squeezes the second connecting hose, so that the large blood clots can be processed quickly and there is no need for multiple cleanings. Description of the Drawings
