Abstract
Description
Technical Field
[0001] This utility model relates to the field of intestinal tube insertion technology, specifically to a guiding device for assisting intestinal tube insertion. Background Technology
[0002] Intestinal tube placement plays several important roles and has significant clinical benefits. First, it provides effective enteral nutritional support, especially for patients unable to eat normally due to illness or surgery. The tube delivers nutritional solutions directly to the small intestine, ensuring adequate calories and nutrients to promote recovery. Second, intestinal tubes can be used for drug administration, particularly for medications requiring local action within the intestines. The tube allows for direct delivery to the affected area, improving treatment efficacy. Furthermore, intestinal tube placement helps reduce intestinal pressure, prevents and alleviates intestinal obstruction, and reduces intestinal gas and fluid accumulation, thereby lowering the risk of complications. For critically ill patients, intestinal tube placement can also reduce the risk of gastric reflux and aspiration, lowering the incidence of aspiration pneumonia and improving patient safety and quality of life.
[0003] Although intestinal tube placement is widely used in clinical practice, challenges and problems still exist during the procedure. For example, it is difficult to adjust the direction of the intestinal tube insertion end during the insertion process. Furthermore, patients with esophageal stricture, achalasia, etc., have slightly different tube placement paths than usual, which can lead to difficulties in the tube placement procedure. For these patients with difficult tube placement, detailed imaging examinations and image-guided techniques, such as X-ray, ultrasound, and gastroscopy, are required to assist in the tube placement. This is costly, complex, and has a low success rate. Utility Model Content
[0004] To address the shortcomings of difficulty in adjusting the insertion end during intestinal tube placement and the challenge of performing tube placement on patients with complex conditions, this invention provides an auxiliary intestinal tube placement device that facilitates adjustment of the intestinal tube during placement, is simple and convenient to operate, and has a high success rate.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A guiding device for assisting intestinal tube placement includes a guide wire and an adjustment control handle; one end of the guide wire is connected to the adjustment control handle, and the other end is connected to a camera, and an inflatable and deflated airbag assembly is also connected to the guide wire; the main body of the adjustment control handle is a handheld part, an adjustment block is movably installed in the middle of the handheld part, and a display screen is connected to the top, wherein the guide wire passes through the handheld part and connects to the adjustment block; the camera is provided with a data transmission line, and the data transmission line is installed along the guide wire and connected to the display screen.
[0007] Furthermore, the airbag assembly includes a limiting airbag and an inflation tube, wherein the limiting airbag is fixedly sleeved on the guide wire; the inflation tube is arranged along the guide wire, the tube body is connected to the inflation airbag, and the top extends outward after reaching the handle, wherein the top of the inflation tube is also provided with a switch. During inflation, the switch is first turned on, and then air is inflated using a syringe or a micro air pump, etc. When the airbag expands and presses against the jejunal tube, the switch is turned off. At this time, the guide wire and the jejunal tube are stably connected together. When the insertion is completed, the switch is turned on to allow the gas inside the airbag to be discharged through the inflation tube. At this time, the guide wire is separated from the jejunal tube, and the guide wire can be directly pulled out. The airbag assembly has a simple structure and is easy to manufacture.
[0008] Furthermore, the guide wire body is a sleeve, inside which are provided an optical fiber channel, a data line channel for data transmission line installation, and a tubular channel for the inflation tube, wherein the optical fiber channel is equipped with optical fibers. Various required wires are integrated and installed inside the guide wire, making its structure compact.
[0009] Furthermore, there are two limiting airbags, one located in the middle of the guide wire and the other near the bottom. These limiting airbags, positioned in the middle and near the bottom of the guide wire, allow for better connection between the guide wire and the jejunal tube, facilitating adjustment of the jejunal tube during insertion.
[0010] Furthermore, the limiting block includes an arc-shaped track and a rotating ring. The arc-shaped track is installed in the middle of the handheld part, and its outer periphery is fixedly connected to the inner wall of the handheld part. The rotating ring is rotatably nested in the arc-shaped track. The guide wire passes through the handheld part and the through hole in sequence and then connects to the camera. If the direction of the jejunal tube needs to be adjusted during tube placement, the rotating ring can be driven to rotate along the arc-shaped track, which simultaneously drives the guide wire to rotate. When the guide wire rotates, it drives the jejunal tube to adjust its direction, thereby realizing the adjustment operation of the tube placement.
[0011] Furthermore, the arc-shaped track has an arc-shaped protrusion in the middle; the rotating ring has a groove that mates with the protrusion, and the rotation of the rotating ring is achieved through the engagement of the groove and the protrusion. The arc-shaped track and the rotating ring are rotated together by the engagement of the protrusion and the groove, which results in a stable and reliable structure that is easy to adjust and use.
[0012] Furthermore, the rotating ring has a through hole in the middle and a threaded hole on the side that connects to the through hole. A screw is installed in the threaded hole, and the guide wire is limited by the screw after passing through the through hole. The screw can fix and restrict the guide wire in the through hole, so that it will not get out of control during adjustment, which facilitates adjustment when inserting the jejunal tube.
[0013] How to use:
[0014] To facilitate guidewire adjustment, a spring-loaded data transmission line is used, allowing for expansion and contraction within a certain adjustment range. During use, the guidewire is inserted into the jejunum tube, with the camera protruding from the tube. The balloon assembly is then inflated, inflating and pressing against the jejunum tube. Once inflated, the jejunum tube and guidewire are connected, allowing for jejunum tube placement. The guidewire, connected to the jejunum tube, is then inserted into the patient's body. The camera captures images of the internal environment of the tube placement and transmits them to a display screen via the data transmission line. When the tube needs directional adjustment, an adjustment block moves, which in turn moves the guidewire, thus moving the jejunum tube to adjust its direction. When the jejunum tube reaches the desired placement position, the balloon assembly is deflated, separating from the jejunum tube. The guidewire is then withdrawn, completing the placement procedure. The number of limiting balloons can be adjusted according to actual needs.
[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0016] 1. The auxiliary intestinal tube placement guidance device provided by this utility model, through the integration and use of a camera, display screen, inflatable and deflated balloon assembly and adjustment block, realizes real-time visualization and precise directional adjustment during the tube placement process, significantly improving the success rate of tube placement, and is especially suitable for patients with complex conditions such as esophageal stricture and achalasia; the device simplifies the operation process, reduces operation time and complexity, reduces the risk of patient discomfort and complications caused by multiple tube placement attempts, and improves patient comfort and safety. At the same time, compared with traditional image-guided technology, this device is easier to operate, reduces dependence on expensive equipment, lowers medical costs, and improves clinical work efficiency.
[0017] 2. This utility model achieves simple and rapid connection or separation of the guide wire and jejunal tube through the combination of a limiting airbag and an inflation tube, simplifying the insertion process. It also features a simple structure and is easy to manufacture. The guide wire body integrates fiber optic channels, data cable channels, and tubing channels, ensuring a compact structure and flexible operation, improving visibility and safety during insertion. The dual limiting airbag layout enhances the connection stability between the guide wire and the jejunal tube, facilitating directional adjustment. The limiting block uses a design combining an arc-shaped track and a rotating ring, which not only enhances structural stability but also simplifies the directional adjustment process. Screws secure the guide wire, ensuring control during adjustment, avoiding operational errors, and improving the safety and efficiency of insertion. Attached Figure Description

Detailed Implementation
[0024] The present invention will be further described below with reference to the accompanying drawings.
[0025] Example 1: A guiding device for assisting intestinal tube placement includes a guide wire 1 and an adjustment control handle 2; one end of the guide wire 1 is connected to the adjustment control handle 2, and the other end is connected to a camera 3, and an airbag assembly 4 for inflation and deflation is also connected to the guide wire; the main body of the adjustment control handle 2 is a handheld part 21, an adjustment block 22 is movably installed in the middle of the handheld part 21, and a display screen 23 is connected to the top, wherein the guide wire 1 passes through the handheld part 21 and connects to the adjustment block 22; the camera 3 is provided with a data transmission line 31, and the data transmission line 31 is connected to the display screen 23 after being installed along the guide wire.
[0026] To facilitate adjustment of the guidewire 1, the data transmission line 31 is a spring wire, which can extend and retract within a certain adjustment range for easy adjustment. In use, the guidewire 1 needs to be connected to the jejunal tube. The guidewire 1 is passed through the jejunal tube, and the camera 3 of the guidewire 1 extends out of the jejunal tube. Then, the balloon assembly 4 is inflated. Once inflated, the balloon assembly 4 presses against the jejunal tube, connecting the jejunal tube to the guidewire 1. The jejunal tube can then be inserted. Finally, the guidewire 1 connected to the jejunal tube is inserted into the patient's body. Camera 3 captures images of the patient's internal environment during catheter placement and transmits them to display screen 23 via data transmission line 31 for easy catheter placement. When the catheter needs to be adjusted, the adjustment block 22 is driven to move, which in turn moves the guidewire, thereby moving the jejunum tube to adjust its direction and facilitate catheter placement. When the jejunum tube is guided to the required placement position, the balloon assembly 4 is deflated, separating it from the jejunum tube. The guidewire can then be withdrawn to complete the entire catheter placement operation. The number of limiting balloons 41 can be set according to actual needs.
[0027] Before performing catheter placement on a patient, existing AI technology can be used to assist in the placement. Specifically, the patient first undergoes a CT scan to obtain relevant data in the coronal and sagittal planes. The CT data is then copied to a USB drive and imported into a computer. The computer's AI program analyzes the data and generates a data model of the patient's gastrointestinal tract. After the model is generated, the catheter is placed under guidance using a guiding device. This process is simpler and more accurate.
[0028] Example 2: The difference from Example 1 is that the airbag assembly 4 includes a limiting airbag 41 and an inflation tube 42. The limiting airbag 41 is fixedly sleeved on the guide wire 1. The inflation tube 42 is arranged along the guide wire, with its body communicating with the airbag and its top extending outwards after reaching the handle. A switch 43 is also provided at the top of the inflation tube 42. The inflation tube 42 is made of corrugated tubing, allowing for telescopic adjustment, ensuring that the guide wire 1's rotational adjustment does not affect the normal use of other components. During inflation, the switch 43 is first opened, and then air is inflated using a syringe or micro-pump. When the airbag expands and presses against the jejunal tube, the switch 43 is closed. At this point, the guide wire 1 is stably connected to the jejunal tube. When the insertion is complete, the switch 43 is opened, allowing the gas inside the airbag to be discharged through the inflation tube 42. At this point, the guide wire 1 separates from the jejunal tube, and the guide wire can be directly pulled out. The airbag assembly 4 has a simple structure and is easy to manufacture.
[0029] The limiting block includes an arc-shaped track 221 and a rotating ring 222. The arc-shaped track 221 is installed in the middle of the handheld part 21, and its outer periphery is fixedly connected to the inner wall of the handheld part 21. The rotating ring 222 is rotatably nested in the arc-shaped track 221. The guide wire 1 passes through the handheld part 21 and the through hole 225 in sequence and is then connected to the camera 3. If the direction of the jejunal tube needs to be adjusted during tube placement, the rotating ring 222 can be driven to rotate along the arc-shaped track 221, which simultaneously drives the guide wire 1 to rotate. When the guide wire 1 rotates, it drives the jejunal tube to adjust its direction, thereby realizing the adjustment operation of the tube placement.
[0030] Example 3: The difference from Example 2 is that the main body of the guide wire 1 is a sleeve. Inside the sleeve are an optical fiber channel, a data line channel for installing the data transmission line 31, and a tubular channel for the inflation tube 42. The optical fiber channel is equipped with optical fibers 11. Various necessary wires are integrated inside the guide wire 1, making its structure compact.
[0031] There are two limiting airbags 41, one located in the middle of the guide wire 1 and the other near the bottom. The limiting airbags 41 located in the middle and near the bottom of the guide wire 1 allow for better connection between the guide wire 1 and the jejunal tube, facilitating adjustment of the jejunal tube during insertion.
[0032] The arc-shaped track 221 has an arc-shaped protrusion 223 in the middle; the rotating ring 222 has a groove 224 that mates with the protrusion 223, and the rotating ring 222 is rotatably connected by the groove 224 and the protrusion 223. The arc-shaped track 221 and the rotating ring 222 are rotatably connected by the protrusion 223 and the groove 224, which is structurally stable and reliable, easy to adjust, and convenient to use.
[0033] The rotating ring 222 has a through hole 225 in the middle and a threaded hole on the side that connects to the through hole 225. A screw 226 is installed in the threaded hole. The guide wire 1 passes through the through hole 225 and is limited by the screw 226. The screw 226 can fix and limit the guide wire 1 in the through hole 225, so that it will not get out of control during adjustment, which facilitates adjustment when inserting the jejunal tube.
