Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a fluorescent positioning gastric tube used in gastrectomy surgery. Background Art

[0002] A gastric tube is a medical device used to treat gastric diseases and provide nutritional support.

[0003] In sleeve gastrectomy, the cutting edge of the stomach to be removed needs to be determined before cutting with a cutting stapler. The commonly used method is to insert a gastric tube close to the lesser curvature of the stomach until the pylorus. The doctor determines the cutting edge of the sleeve gastrectomy by observing the bulge of the gastric tube under laparoscopy. This method of determining the cutting edge has high requirements for the doctor, and misjudgment may lead to failure of the operation and harm to the patient.

[0004] Existing technology has defects and reasons:

[0005] Patients who need weight loss surgery have thicker stomach tissue, so doctors need to repeatedly confirm the position of the gastric tube during the operation to prevent the laparoscopic stapler from accidentally cutting and anastomosing the gastric tube and causing the operation to fail. The repeated confirmation process will prolong the operation time and indirectly increase the difficulty and risk of the operation. Utility Model Content

[0006] The utility model aims to provide a fluorescent positioning gastric tube used in gastrectomy surgery, which can solve the above-mentioned defects.

[0007] The utility model is realized by the following technical scheme: a fluorescent positioning gastric tube used in gastrectomy surgery, which comprises a gastric tube, an LED fluorescent light strip and a cable;

[0008] The LED fluorescent light strip is fixedly connected to the inside of the gastric tube, and a certain operating space is left between the LED fluorescent light strip and the gastric tube;

[0009] The rear end of the LED fluorescent light strip is connected to a cable, and the portion of the cable extending into the gastric tube is also fixedly connected to the inside of the gastric tube.

[0010] Compared with the previous technology, the beneficial effects of the utility model are:

[0011] 1. The LED fluorescent light strip emits fluorescence from the inside of the gastric tube to the outside. As a fluorescent positioning light source, the fluorescent endoscope camera system uses the fluorescent mode to identify the position of the fluorescent light source, which is equivalent to identifying the position of the gastric tube and displaying it on the screen.

[0012] 2. Using the fluorescent mode of the fluorescent endoscope camera system, the doctor can directly observe the position of the gastric tube through the camera system during the operation, thereby improving the efficiency of the operation, reducing the time to determine the resection margin and the patient's pain, and reducing the risk of the operation.

[0013] 3. The way the LED fluorescent light strip produces fluorescence is safe and non-toxic and will not cause harm to the human body. In addition, the size of the light strip is designed to fit the gastric tube and is fixed in the gastric tube with enough space. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the utility model.

[0015] Explanation of numbers: 1. Gastric tube, 2. LED fluorescent light strip, 3. Cable. DETAILED DESCRIPTION

[0016] The utility model is described in detail below in conjunction with the accompanying drawings, but the protection content of the utility model is not limited to the following:

[0017] like Figure 1 As shown, a fluorescent positioning gastric tube 1 used in gastrectomy surgery comprises a gastric tube 1, an LED fluorescent light strip 2 and a cable 3;

[0018] The LED fluorescent light strip 2 is fixedly connected to the inside of the gastric tube 1, and a certain operating space is left between the LED fluorescent light strip 2 and the gastric tube 1;

[0019] The rear end of the LED fluorescent light strip 2 is connected to the cable 3, and the portion of the cable 3 extending into the gastric tube 1 is also fixedly connected to the inside of the gastric tube 1. Fixedly connecting the LED fluorescent light strip 2 and the portion of the cable 3 extending into the gastric tube 1 to the inside of the gastric tube 1 can prevent sliding and reduce the impact on the operation.

[0020] The LED fluorescent light strip 2 fits the inner wall of the gastric tube 1, and the portion of the cable 3 extending into the gastric tube 1 also fits the inner wall of the gastric tube 1. Fitting the LED fluorescent light strip 2 to the inner wall of the gastric tube 1 can make the operation space larger.

[0021] The head end of the LED fluorescent light strip 2 is flush with the head end of the gastric tube 1 .

[0022] The way LED fluorescent light strips produce fluorescence is safe and non-toxic, and will not cause harm to the human body. In addition, the size of the light strip is designed to fit the gastric tube and is fixed in the gastric tube with enough space. The LED fluorescent light strip emits fluorescence from the inside of the gastric tube to the outside for guiding illumination. As a fluorescent positioning light source, the fluorescent endoscope camera system uses the fluorescent mode to identify the position with the fluorescent light source, that is, the gastric tube position, and display it on the screen.

[0023] When in use, the gastric tube is inserted into the human body, and then the fluorescent mode of the fluorescent endoscope camera system is used to allow the doctor to directly observe the position of the gastric tube through the camera system during the operation, thereby improving the efficiency of the operation, reducing the time to determine the resection margin during the operation and the patient's pain, and reducing the risk of surgery.

[0024] Although the utility model uses specific embodiments and their alternatives to illustrate and describe the utility model, it should be understood that various changes and modifications can be implemented as long as they do not deviate from the spirit and scope of the utility model. Therefore, it should be understood that except for the limitations of the attached claims and their equivalents, the utility model is not limited in any sense.
