Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical consumables, and in particular to a gastric tube with a continuous light source. Background Technology
[0002] A gastric tube is a medical device used to treat stomach ailments and provide nutritional support.
[0003] Before cutting with a stapler during sleeve gastrectomy, it is necessary to determine the resection margin of the stomach to be removed. A common method is to insert a gastric tube close to the lesser curvature of the stomach until it reaches the pylorus. Under laparoscopy, the surgeon determines the resection margin of the sleeve stomach by observing the bulge of the gastric tube. This method of determining the resection margin requires a high level of skill from the surgeon; misjudgment may lead to surgical failure and harm to the patient.
[0004] Currently, patients requiring bariatric surgery generally have thicker stomach tissue. Therefore, surgeons need to repeatedly confirm the position of the gastric tube during surgery to avoid accidental cutting and anastomosis of the gastric tube by the endoscopic stapler, which could lead to surgical failure. Conventional gastric tubes with contrast agents require X-ray equipment for contrast, which is harmful to patients and prolongs the surgical time, indirectly increasing the difficulty and risk of the procedure. Commercially available gastric tube lamps with light sources have large spacing between the LEDs, resulting in discontinuous light and dark areas in the field of view. Furthermore, current power supply methods are combined, making it impossible to separate the power supply and light source. Due to limited power supply capacity, this cannot meet the needs of different surgical durations. Utility Model Content
[0005] The purpose of this invention is to provide a gastric tube with a continuous light source, which can provide a continuous and stable light source for surgery, ensure that there are no dark areas in the field of vision, and avoid damage to the gastric tube by cutting instruments.
[0006] This utility model is achieved through the following technical solution: the main body is a gastric tube, and a light strip is provided on the inner lumen of the gastric tube, extending in the front-to-back direction. The light strip forms continuous light after being powered on; the tail of the light strip extends out of the gastric tube and is connected to a power source.
[0007] Compared with previous technologies, the beneficial effects of this utility model are as follows:
[0008] 1. The gastric tube is equipped with a light strip, which contains continuously distributed light-emitting beads. By lighting the light strip, continuous light can be provided, giving the surgeon a bright field of vision, accurately locating the gastric tube, and avoiding damage to the gastric tube during the operation.
[0009] 2. The power supply adopts a replaceable battery design, which can select or replace the battery according to different operation durations to meet the needs of different operations;
[0010] 3. It is still equipped with a developing line, which can determine the position of the tube inside the body through optical equipment;
[0011] 4. The tip of the gastric tube is hemispherical, which can reduce mucosal damage during the insertion of the gastric tube;
[0012] 5. The light strip is equipped with an external indicator light, making it easy to determine the continuity of the circuit from the outside. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings:
[0020] like Figure 1 As shown: A gastric tube with a continuous light source, the main body is a gastric tube 1, and a light strip 12 is provided in the inner cavity of the gastric tube 1, which extends in the front-to-back direction. The light strip 12 forms continuous light when it is powered on; the tail of the light strip 12 extends out of the gastric tube 1 and is connected to a power source.
[0021] The tail end of the gastric tube 1 is connected to a power supply housing 2; the power supply is installed inside the power supply housing 2 and is electrically connected to the light strip 12.
[0022] The front side wall of the gastric tube 1 has several tube body through holes 11; the side wall of the power supply housing 2 is also fixed with a two-way valve 3, which extends through the power supply housing 2 into the tail of the gastric tube 1 and connects with the tube body through holes 11.
[0023] The power supply casing 2 has a two-way valve and a gastric tube and tube body through hole to form a passage with flushing and suction effects.
[0024] The power source is located in the battery 4 installed inside the power source housing 2. The tail of the light strip 12 is electrically connected to the control board 13, which is located inside the power source housing 2. The control board 13 is electrically connected to one pole of the power source and is also electrically connected to the other pole of the power source through a conductive plate.
[0025] Most LED strip lights are equipped with a control board, which is electrically connected to the power supply. Here, the control board is placed inside the power supply housing 2, primarily because housing 2 is easily designed to accommodate and limit the space for the control board. This also facilitates the connection of the control board, the conductive plate, and one pole of the power supply.
[0026] The conductive piece is equipped with an on / off switch 5, and the on / off switch 5 is operated to control the current in the conductive piece to be turned on and off; the on / off switch 5 is installed at the tail of the power supply housing 2.
[0027] The on / off switch 5 is installed inside the switch housing 6, and the switch housing 6 is detachably connected to the tail of the power supply housing 2;
[0028] The switch housing 6 can be separated from the power supply housing 2 to allow for battery replacement.
[0029] The conductive piece is divided into a lower conductive piece 71, a side conductive piece 72, and an upper conductive piece 73; both the upper conductive piece 73 and the side conductive piece 72 are mounted on the on / off switch 5; when the switch housing 6 is connected to the power supply housing 2, the upper conductive piece 73 is in contact with one pole of the battery 4, and the upper end of the lower conductive piece 71 overlaps with the side conductive piece 72; the lower end of the lower conductive piece 71 is electrically connected to the control board 13.
[0030] Here, the lower conductive piece 71, control board, battery negative terminal, battery, battery positive terminal, upper conductive piece 73, on / off switch 5 (in the on state) and side conductive piece 72 are connected in sequence to form a closed loop, thereby forming a circuit circuit.
[0031] When switch 5 is turned on, the LED strip lights up; when switch 5 is turned off, the circuit is broken and the LED strip goes out.
[0032] The inner wall of the gastric tube 1 is also coated with radiopaque lines 8 extending in the front-to-back direction. Radiopaque imaging is performed using an X-ray imaging device, allowing the gastric tube to be quickly located by the radiopaque lines if it accidentally separates from the light strip during surgical cutting.
[0033] The tip of the gastric tube 1 is a hemispherical tip 15, which is seamlessly fused to the body of the gastric tube 1. The hemispherical tip 15 is fused to the gastric tube 1 as one piece without any step, which ensures that mucosal damage is reduced when the gastric tube 1 is inserted or removed.
[0034] The continuous light-emitting beads on the light strip 12 are divided into two groups, left and right. The group of light-emitting beads on the left side emits red light or fluorescent light, and the group of light-emitting beads on the right side emits red light or fluorescent light, so that the light strip 12 can form a full red light strip 12, a full fluorescent light strip 12, or a mixed red and fluorescent light strip 12.
[0035] The light strip here can be red, fluorescent, or a combination of both. Different developing effects are provided depending on the requirements. When using a combined light source, red and fluorescent light are used in conjunction with different equipment for developing. Red or fluorescent LEDs are distributed on both sides of the light strip, and different light sources are switched via a switch housing. When powered on, it provides continuous light, allowing for precise cutting.
[0036] The light strip has continuously distributed LED beads, and a power indicator light 9 is located at the end of the light strip 12. When the power indicator light is lit, the operator can determine the conductivity of the light strip based on the status of the power indicator light, making it easy to identify the on / off state.
[0037] like Figure 5 As shown: Additionally, the switch housing is guided onto the power supply housing and fastened by rotation. The gap at the tail of the latch gradually decreases from large to small, controlling the assembly gap between the switch housing and the power supply housing. This connection method primarily ensures a constant axial positional fit between the switch housing and the power supply housing. After the switch housing and the power supply housing are connected, the lower conductive piece 71 and the side conductive piece 72 overlap each other. This connection method is a conventional structure, and therefore will not be described further in this application.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
