Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a digestive tract endoscope. Background Art

[0002] The human digestive tract includes organs such as the stomach, small intestine, and large intestine. The small intestine is a section of intestine connecting the stomach and the cecum. From top to bottom, the small intestine is divided into the duodenum, jejunum, and ileum, which are piled up in the abdominal cavity. The length of the small intestine is about 5 to 7 meters. Because of the contraction and peristalsis of the intestinal muscles, the length of the small intestine in the body is about 3 to 5 meters.

[0003] However, existing enteroscopic surgery is difficult to perform and often requires very high surgical skills from the doctor. The main reasons are: (1) The small intestine is very long and has many bends and folds, making it difficult for the enteroscope to pass through; (2) In order to facilitate the insertion of the endoscope, the enteroscope is covered with a sleeve with an air bag. The sleeve is large in size and the sleeve increases the hardness of the enteroscope, making it more difficult to turn the intestinal tract and difficult to insert the endoscope into the small intestine; if the enteroscope is improperly operated, it is easy to cause bleeding, perforation, and mesenteric root tearing. Oral enteroscopy may also induce pancreatitis. (3) Examinations and related treatments of the digestive system such as the stomach, large intestine and small intestine are performed by different digestive tract endoscopes such as gastroscopy, colonoscopy and small enteroscope. The procedures are complicated and the cycle is long, which increases the pain of patients. In addition, the incidence of biliary and pancreatic diseases increases after patients complete upper gastrointestinal diversion surgeries such as Billroth II gastrectomy, pancreaticoduodenectomy, Roux-en-Y gastrointestinal and biliary intestinal anastomosis. Biliary and pancreatic diseases often require endoscopic treatment with the help of retrograde cholangiopancreatography (ERCP) technology. However, due to changes in normal anatomical structure, significant prolongation of the input loop path, and adhesion and twisting of the intestinal loop, it is also difficult for the endoscope to enter the bile and pancreatic duct.

[0004] Therefore, there is an urgent need for a digestive tract endoscope to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide a gastrointestinal endoscope, which reduces the difficulty of inserting the endoscope, makes the operation convenient, can be applied to the inspection of multiple parts such as the upper and lower gastrointestinal tract, and can reduce the cost.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] like Figure 1 and Figure 2 As shown, the present invention provides a digestive tract endoscope, including a scope body 1 and a traction assembly 2. The scope body 1 can move in the digestive tract, and a first channel 11 is provided in the scope body 1. The two ends of the first channel 11 respectively penetrate the outer wall of the scope body 1 and the front end of the scope body 1, and a camera 10 is provided at the front end of the scope body 1; the traction assembly 2 can be movably arranged in the first channel 11, and the traction assembly 2 includes a traction member 21 and a first balloon 22. The traction member 21 can move in the digestive tract, and the first balloon 22 is sleeved on the traction member 21. The first balloon 22 can shrink or expand. When the first balloon 22 expands, the first balloon 22 can abut against the inner wall of the digestive tract; the front end of the scope body 1 is sleeved with a second balloon 12. The second balloon 12 can shrink or expand. When the second balloon 12 expands, the second balloon 12 can abut against the inner wall of the digestive tract.

[0034] The digestive endoscope of the present invention removes the sleeve provided on the outer surface of the digestive endoscope, and sets the traction component 2 in the digestive endoscope, that is, in the mirror body 1 of the present invention, so as to reduce the overall volume of the digestive endoscope, improve the passability, reduce the difficulty of inserting the mirror, and make the operation convenient. In addition, the overall volume of the digestive endoscope is small, so that the digestive endoscope can be applied to the inspection of multiple parts such as the upper and lower digestive tracts. Specifically, with the help of the existing peracetic acid disinfection technology, the digestive endoscope can be entered orally or anally to complete the inspection and treatment of all digestive tracts, including the stomach, large intestine, small intestine, and bile and pancreatic ducts, etc., and can complete the ERCP treatment of bile and pancreatic diseases after upper digestive tract diversion (after Billroth-II gastrectomy, pancreaticoduodenectomy, Roux-en-Y surgery, etc.), which has strong applicability and can greatly save costs.

[0035] Furthermore, when the digestive tract endoscope of the present invention advances in the digestive tract, the traction member 21 is in front and the scope body 1 is in the back. The volume of the traction member 21 is smaller than that of the scope body 1, which facilitates passing through bends and folds, further improving passability. In addition, when the digestive tract endoscope is short, the first balloon 22 and the second balloon 12 are alternately expanded and contracted, and the operator moves the traction member 21 and the scope body 1 continuously, so that the entire long digestive tract can be inspected, which can reduce costs.

[0036] When operating the digestive tract endoscope, the traction component 2 is not inserted first, and the scope body 1 is inserted through the mouth first, and then the operating knob at the rear end of the scope body 1 is twisted to make the scope body 1 enter the stomach and reach the pylorus of the stomach. When the digestive tract endoscope enters the duodenum in the small intestine from the pylorus, the second balloon 12 is inflated and positioned, and the operator inserts the traction component 2 from the outer wall of the scope body 1, and makes it pass through the first channel 11 in sequence and pass out from the front end of the scope body 1. During the insertion process, the first balloon 22 is in a contracted state. When the operator inserts the traction member 21 to a certain position, so that the first balloon 22 is located at a certain position at the front end of the scope body 1, the first balloon 22 is inflated and abuts against the inner wall of the digestive tract. Then the second balloon 12 is contracted, and the operator moves the scope body 1 forward to detect the digestive tract. At the same time or afterwards, the operator pulls the traction member 21 outward, so that the first balloon 22 drives the digestive tract at the rear end to curl outward. Afterwards, the second balloon 12 is inflated and positioned, the first balloon 22 is contracted, and the operator continues to move the traction member 21 inward. After moving to a certain position, the first balloon 22 is inflated and abuts against the inner wall of the digestive tract, and the above process is repeated. In this process, the mirror body 1 moves forward along with the traction member 21 and is always located at the rear end of the first balloon 22. The image in the digestive tract is captured by the camera 10 on the mirror body 1 to detect the digestive tract, wherein the moving power of the mirror body 1 is also completed by the operator. Optionally, the mirror body 1 is a silicone tube. In this process, the expansion of the second balloon 12 plays a fixed limiting role on the digestive tract. When the first balloon 22 is contracted, the curled digestive tract can be prevented from returning to the state before curling, so that the digestive tract endoscope has a better moving effect in the digestive tract. In addition, the expansion of the second balloon 12 can also position the mirror body 1 in the digestive tract, which is convenient for detecting specific parts of the digestive tract.

[0037] It should be noted that during use of the digestive tract endoscope of the present invention, the traction component 2 may be inserted or not inserted for the digestive tract with a larger inner diameter such as the esophagus, stomach, duodenum and colon. However, for the small intestine with a smaller inner diameter or the bile and pancreatic duct of a postoperative patient that cannot be directly reached by the endoscope 1, the traction component 2 needs to be inserted.

[0038] Optionally, in this embodiment, the first balloon 22 and the second balloon 12 are both inflatable balloons, and the digestive tract endoscope further includes a first inflatable component and a second inflatable component, the first inflatable component is used to inflate and deflate the first balloon 22, and the second inflatable component is used to inflate and deflate the second balloon 12.

The flow channel 2122 is provided in the first soft catheter 212, and the inner cavity of the first balloon 22 is communicated with the flow channel 2122. The flow channel 2122 in the first soft catheter 212 can be inflated or liquid can be injected to achieve the expansion of the first balloon 22, so that the structure is compact and space is saved. The first balloon 22 and the first soft catheter 212 are integrated, so that the structure is simple and easy to install. Furthermore, the flow channel 2122 is an annular inner cavity, and the flow channel 2122 is arranged at intervals outside the penetration channel 2121. Such an arrangement can ensure that the first soft catheter 212 is uniformly stressed and convenient for passing the guide wire 211. In other embodiments, the penetration channel 2121 and the flow channel 2122 are arranged side by side.
