Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a cystic tube for surgical examination of small intestine Crohn's disease lesions. Background Technique

[0002] In the medical industry, Crohn's disease is prone to occur in young people and is manifested as chronic recurrent non-specific intestinal inflammation of the digestive tract. As the disease progresses, patients may develop intestinal stenosis leading to intestinal obstruction. When drug treatment is ineffective, surgical resection of the diseased intestinal tract is required to maintain intestinal patency. In clinical practice, some Crohn's disease patients may have multiple-segment small intestine stenosis. The author has received patients with more than 10 small intestine stenoses at the same time. These intestinal stenoses are often unevenly distributed and far apart. Some intestinal stenoses are relatively hidden and even difficult to clearly identify the stenosis location through intraoperative palpation. Once these intestinal stenoses are missed, serious medical consequences are bound to occur.

[0003] Therefore, we propose a cystic tube for surgical examination of small intestine Crohn's disease lesions, aiming to facilitate the diagnosis and dilation of intestinal stenosis during surgery. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a cystic tube for surgical examination of small intestine Crohn's disease lesions, which can effectively solve the problems in the background technique.

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

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0021] As Figures 1-5 shown, a cystic tube for surgical examination of small intestine Crohn's disease lesions includes a B pipeline 1. An adjustable expansion structure 2 is fixedly installed on the surface of the B pipeline 1. A pushing-in structure 4 is fixedly installed on the surface of the B pipeline 1 on one side of the adjustable expansion structure 2. The lower end of the adjustable expansion structure 2 is fixedly connected to a screw propulsion needle 3;

[0022] The adjustable expansion structure 2 includes a pipe A 201, a bladder A 202 and a connector A 203. The bladder A 202 is fixedly installed on the surface of the pipe B 1 near the upper end. The pipe A 201 penetrates through the inside of the pipe B 1, and the lower end of the pipe A 201 passes through the pipe B 1 and is connected to the connector A 203. The upper end of the pipe A 201 passes through the pipe B 1 and is communicated with the bladder A 202. The lengths of the pipe A 201, the pipe C 401 and the pipe B 1 are set as required. The pushing-in structure 4 includes a pipe C 401, a bladder C 402, a connector C 403 and a self-sealing rubber sheet 404. The bladder C 402 is fixedly installed on the surface of the pipe B 1 above the bladder A 202. The pipe C 401 penetrates through the inside of the pipe B 1, and the lower end of the pipe C 401 passes through the pipe B 1 and is connected to the connector C 403. The upper end of the pipe C 401 passes through the pipe B 1 and is communicated with the bladder C 402. A self-sealing rubber sheet 404 is fixedly installed in the insertion port of the connector C 403. When the syringe needle is pulled out, the insertion hole is automatically blocked by the rubber resilience due to the very small needle hole. A diversion hole B 101 is opened on the surface of the pipe B 1 between the bladder C 402 and the bladder A 202. The diversion hole B 101 is used for liquid drainage. The lower end of the pipe B 1 is connected to a connector B 102. The screw propulsion needle 3 includes a syringe needle 301, a fixing plate 302, a screw hole 303, a sliding hole 304, a pushing plate 305, a piston 306, a small bearing 307, a screw rod 308 and a sliding rod 309. A fixing plate 302 is fixedly installed inside the lower port of the syringe needle 301. A screw hole 303 is opened in the middle of the fixing plate 302. Sliding holes 304 are opened on both sides of the screw hole 303 on the surface of the fixing plate 302. A pushing plate 305 is movably installed inside the syringe needle 301. A piston 306 is fixedly installed on the upper surface of the pushing plate 305. A small bearing 307 is fixedly installed inside the pushing plate 305. The pushing plate 305 is movably connected to the screw rod 308 through the small bearing 307. Sliding rods 309 are fixedly connected to both sides of the screw rod 308 on the surface of the pushing plate 305. Since the screw rod 308 and the pushing plate 305 are movably connected through the small bearing 307, rotating the screw rod 308 can cause the pushing plate 305 to push and suck in the syringe needle 301. The sliding rods 309 are mainly used to limit the rotation of the pushing plate 305 so that the pushing plate 305 moves axially along the screw rod 308. The screw rod 308 is in screw connection with the screw hole 303. The two sliding rods 309 are respectively slidably arranged in the two sliding holes 304. The connector of the syringe needle 301 is matched with the connector A 203. The connector of the syringe needle 301 can just be hermetically inserted and fixed with the port of the connector A 203.

[0023] It should be noted that the present utility model is a cystic tube for surgical examination of small intestine Crohn's lesions. When in use, first, the end of the B pipeline 1 provided with the C cyst 402 is inserted into the incised small intestine for examination. After insertion, the self-sealing rubber sheet 404 is punctured through with a syringe needle and inserted into the C socket 403, and water is injected into the C cyst 402 through the C pipeline 401 to inflate the C cyst 402. Then, the doctor can move the small intestine part bulged by the C cyst 402 and slowly insert the B pipeline 1 into the small intestine. If the inside of the small intestine is narrow and the B pipeline 1 cannot even pass through the narrow part, it is determined that only surgical resection can be performed. However, some narrow parts are not very serious, resulting in poor food flow in the intestine. At this time, the doctor can move the A cyst 202 to that place, and then rotate the screw rod 308 to push the piston 306 to quantitatively push the liquid in the syringe 301 into the A cyst 202 through the A pipeline 201 according to the preset value on the syringe 301. At this time, the A cyst 202 is inflated with water, so as to expand the small intestine at that place. During the expansion, the expanded state is maintained for half a minute to one minute, and the whole intestine can be examined in this way.
