Description

Technical Field

[0001] The invention relates to the technical field of gastric light tubes, and in particular to a gastric light tube for sleeve gastrectomy. Background Art

[0002] Sleeve gastrectomy, also known as laparoscopic sleeve gastrectomy, is a surgery that involves vertically cutting the greater curvature of the stomach through a laparoscope, creating a small stomach pouch of about 150cc that can hold about 4-5 ounces of food. Limiting the size of the stomach means limiting the amount of food that can be ingested, thereby helping with weight loss.

[0003] In the current sleeve gastrectomy, doctors still use ordinary gastric calibration tubes without lighting function to perform the surgery, which often makes it impossible for doctors to accurately position the tube during the operation, resulting in various accidents during the resection, such as the inability to accurately grasp the size of the stomach to be resected; mistakenly cutting other parts and causing gastric bleeding; the inability to accurately position the tube requires a lot of time to determine the position of the tube, thereby greatly increasing the operation time, etc. Therefore, a gastric light tube for sleeve gastrectomy is proposed herein.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] Example: Refer to Figure 1-Figure 12 , a gastric light tube for sleeve gastrectomy, comprising:

[0040] Silicone tube 1, a long tube made of medical silicone, used to extend into the human body (such as the stomach);

[0041] The plug 12 is a conical component made of medical grade silicone and bonded to the head (also called the insertion end) of the silicone tube 1. Due to the excellent biocompatibility and flexibility of silicone, it can avoid damage to the patient's cavity when the tube is inserted to the greatest extent;

[0042] The suction hole 2 may also be called the flushing hole, which is a channel with a large cross-sectional area inside the silicone tube 1, and is used to flush the patient's gastric bleeding or other body fluids caused by the operation after gastrectomy and suturing, and to extract the waste liquid in the stomach after the flushing is completed. A liquid inlet and outlet hole 101 is provided on the side wall of one end of the silicone tube 1 close to the plug 12. The liquid inlet and outlet hole 101 is used for the cleaning agent in the suction hole 2 to enter the human body, and can also be used for the waste liquid in the human body to enter the suction hole 2;

[0043] The optical fiber jack 3 is arranged in the silicone tube 1, and has a cross-sectional area smaller than the suction hole 2. An insertion opening 11 for the optical fiber jack 3 is arranged on the side wall of the silicone tube 1 near one end of the standard connector 6;

[0044] The external light source device 10 and the light guide optical fiber 7 are inserted into the optical fiber jack 3 from the insertion port 11, and are used to guide the light provided by the external light source device 10 to penetrate the entire gastric light tube during the operation, thereby illuminating the doctor's field of vision and more accurately locating the position of the gastric light tube in the stomach;

[0045] The standard connector 6 is provided at one end of the silicone tube 1 placed outside the human body. It is a plastic part made of medical-grade PC and is used to connect the PC connector and the suction device. The hole on the top can be used by doctors when injecting liquids such as subagar blue.

[0046] One end of the light-guiding optical fiber 7 inserted into the silicone tube 1 is provided with 11 light-guiding points 14 with a spacing of 1 cm, so that the light-guiding optical fiber 7 can emit more powerful light in the patient's stomach, providing lighting effects for doctors during operation.

[0047] To sum up, the main body of the gastric light tube is made of medical-grade silicone, ensuring its softness, biocompatibility and safety. The head is designed with a conical plug 12, which also uses medical-grade silicone to reduce damage to the patient's cavity. Inside the silicone tube 1, there is a larger suction / flushing hole designed to flush and extract waste fluid in the stomach to keep the surgical site clean. At the same time, on the side wall of the silicone tube 1 near the plug 12, there is also a liquid inlet and outlet hole 101 to facilitate the entry of cleaning agents and the discharge of waste fluids.

[0048] In order to provide intraoperative lighting, an optical fiber jack 3 is also provided inside the gastric light tube for inserting a light-guiding optical fiber 7. One end of the light-guiding optical fiber 7 is provided with multiple light-guiding points 14 inside the silicone tube 1, which can emit powerful light, provide the doctor with a clear field of vision, and help the doctor to more accurately locate the gastric light tube in the stomach. The external light source device 10 provides a stable and bright light source, which is transmitted to the patient's stomach through the light-guiding optical fiber 7.

[0049] At the same time, the light-guiding optical fiber 7 is inserted into the optical fiber insertion hole 3 from the side wall of the silicone tube 1 , thereby avoiding contamination of the opening of the standard connector 6 .

[0050] Therefore, the gastric light tube for sleeve gastrectomy combines softness, safety, illumination and convenience, providing great convenience and safety guarantee for doctors during sleeve gastrectomy surgery.

[0051] Reference Figure 1 , Figure 3 , Figure 6-Figure 11 In order to prevent the waste liquid extracted from the human body from being adsorbed on the inner wall of the suction hole 2 and causing contamination to the next liquid medicine injected into the human body, the stomach light tube is further improved as follows:

[0052] An integrally formed partition membrane 4 is provided in the silicone tube 1, and the partition membrane 4 divides the suction hole 2 into a liquid inlet hole 202 and a liquid extraction hole 201, and the liquid extraction hole 201 is connected with one end of the liquid inlet hole 202 inserted into the human body, and a mounting head 19 is fixedly connected in the plug 12, and a first slot 20 and a second slot 21 are provided on the mounting head 19, and the hole wall between the optical fiber jack 3 and the suction hole 2 is inserted into the second slot 21 and fixed to the mounting head 19, and the partition membrane 4 is inserted into the first slot 20 and fixed to the mounting head 19; a partition plate 22 is fixedly connected in the mounting head 19, and a connecting hole 23 is provided on the partition plate 22, and the partition plate 22 is located at the mounting head The side of 19 connected with the liquid extraction hole 201 is fixedly connected with an elastic sealing plate 24. When the liquid extraction hole 201 extracts waste liquid from the body, the elastic sealing plate 24 blocks the connecting hole 23. When the medicine is transported into the body through the liquid inlet hole 202, the medicine pushes the elastic sealing plate 24 to open. The first plug connector 15 and the second plug connector 16 are fixedly installed on the standard connector 6. The first plug connector 15 and the second plug connector 16 are respectively inserted into the liquid inlet hole 202 and the liquid extraction hole 201. The first connector 17 and the second connector 18 are fixedly installed on the standard connector 6. The first connector 17 and the second connector 18 are respectively connected with the first connector 15 and the second connector 16.

[0053] By dividing the suction hole 2 into a liquid inlet hole 202 and a liquid extraction hole 201, the two holes are connected at the end inserted into the human body, but are completely separated by a separation membrane 4 inside the silicone tube 1, thereby effectively avoiding direct contact and cross contamination between waste liquid and liquid medicine.

[0054] With the design of the partition plate 22, the connecting hole 23 and the elastic sealing plate 24 in the mounting head 19, when the extraction hole 201 extracts waste liquid from the body, the elastic sealing plate 24 will block the connecting hole 23 to prevent the waste liquid from flowing back to the liquid inlet hole 202. When the medicine is delivered into the body through the liquid inlet hole 202, the medicine will push the elastic sealing plate 24 to open the connecting hole 23, allowing the medicine to enter the human body smoothly, thereby preventing the medicine input into the human body from being contaminated by the waste liquid on the tube wall, effectively reducing the risk of contamination during the operation, allowing doctors to use the gastric light tube for surgery with more confidence, and improving the safety and success rate of the operation.

[0055] like Fig. 9 As shown, further, the width of the separation membrane 4 is greater than the inner diameter of the suction hole 2. When the medicine is delivered into the body, the medicine enters the liquid inlet hole 202. Under the action of the pressure difference, the flowing medicine drives the middle part of the separation membrane 4 to move toward the liquid extraction hole 201. When the waste liquid in the body is extracted, the waste liquid in the body enters the liquid extraction hole 201. Under the action of the pressure difference, the flowing medicine drives the middle part of the separation membrane 4 to move toward the liquid inlet hole 202.

[0056] The separation membrane 4 is moved into the suction hole 2 under different circumstances to change the apertures of the liquid inlet hole 202 and the liquid extraction hole 201. This can prevent the liquid from being contaminated and prevent the liquid extraction hole 201 from being blocked by lumps in the waste liquid, thereby ensuring smooth delivery of liquid into and extraction of liquid from the human body during treatment.

[0057] like Figure 2 As shown, a developing line 25 is arranged inside the silicone tube 1. The developing line 25 is a line with a facial pattern extruded from the silicone tube 1 after mixing PVC and barium sulfate. The developing line 25 runs through the entire silicone tube 1 and is embedded in the tube wall.

[0058] The developing line 25 can be set to various colors. The doctor can confirm the location of the gastric light tube by irradiating the patient's body with an external developing device. Usually, we also distinguish the models by the color of the developing line 25. For example, purple represents 32FR, red represents 34FR, blue represents 36FR, green represents 38FR, and yellow represents 40FR. FR stands for French, which refers to the outer diameter of the catheter. Usually, 1FR is approximately equal to one-third of a mm.

[0059] As a preferred embodiment of the present invention, a heat shrinkable tube 8 is provided on the silicone tube 1 , and the heat shrinkable tube 8 covers the light-guiding optical fiber 7 exiting the insertion port 11 and then shrinks by heating. The shrunk heat shrinkable tube 8 fixes the light-guiding optical fiber 7 .

[0060] As a preferred embodiment of the present invention: the silicone tube 1 is provided with scale lines 5, which are printed on the wall of the silicone tube 1 with medical-grade ink. The scale lines 5 range from 30 cm to 90 cm, which can help doctors accurately determine the length of the tube that has been inserted during intubation.

[0061] like Figure 1 and Fig.11 , and also includes a stop plate 9, which is sleeved on the silicone tube 1. The stop plate 9 is provided with a wide groove 13 and a narrow groove 26. When the silicone tube 1 is located in the wide groove 13, the silicone tube 1 circulates. When the silicone tube 1 is located in the narrow groove 26, the flow inside the silicone tube 1 stops. The stop plate 9 is a plastic part made of medical-grade ABS, which is used to prevent the flow of liquid in the tube when the doctor needs it, thereby playing a barrier role.

[0062] A method for using a gastric light tube for sleeve gastrectomy comprises the following steps:

[0063] Step 1: insert the assembled gastric light tube into the patient's stomach from the patient's nasal cavity or oral cavity;

[0064] Step 2: Connect the light-guiding optical fiber 7 to the external light source device 10, and connect the first connector 17 and the second connector 18 to two sets of external suction pumps respectively;

[0065] Step 3: When it is necessary to inject a cleaning agent into the patient's body, the cleaning agent is injected into the liquid inlet hole 202 through a suction pump, and the cleaning agent breaks the elastic sealing plate 24 and is discharged through the liquid inlet and outlet hole 101;

[0066] Step 4: When it is necessary to extract the waste liquid inside the human body, start the suction pump to extract the waste liquid inside the human body through the liquid extraction hole 201 and the liquid inlet and outlet hole 101.

[0067] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
