Referring to fig. 1 to 6, a guiding device for gastrectomy in an embodiment of the present invention includes a flexible traction tube 10 and a flexible elbow 20, wherein the elbow 20 is connected to the traction tube 10. In this embodiment, the elbow 20 and the traction tube 10 are both rubber members, so that both the elbow 20 and the traction tube 10 can be pressed into the gastric tube 40, and can adapt to a soft stomach to avoid damaging the stomach. The curved tube 20 is relatively straight at a first end and relatively curved at a second end, and the curved tube 20 is shaped like a banana when not compressed for determining the shape of the residual stomach. The elbow pipe 20 is provided with a plurality of sound holes 21 along the length direction, and sound production parts are arranged in the sound holes 21. The elbow 20 is placed in the stomach through the traction tube 10, the elbow 20 is used for determining the shape of the residual stomach, the elbow 20 is the shape of the residual stomach, and the stomach can be cut off more accurately compared with the elbow 20. Specifically, when the stomach is resected, if the bent tube 20 is touched, the volume of the bent tube 20 is changed, and the air inside and outside the bent tube 20 flows through the sound hole 21, so that the sound production part is triggered to produce sound, a doctor is reminded to change the resection part to ensure that the sound hole 21 does not produce sound, and the shape of the residual stomach is similar to the shape of the bent tube 20. In addition, whether the cutting position is accurate or not is judged through sound, so that the positions of the cutting position and the bent pipe 20 do not need to be observed and compared constantly through naked eyes or visual equipment, the accuracy of the cutting position can be guaranteed at the position which is inconvenient to observe, and the application range is wider.

Further, to avoid the situation that the plurality of sound holes 21 are covered by the stomach wall at the same time and cannot emit sound, the connecting line between any two sound holes 21 is not parallel to the length direction of the elbow 20. In the present application, the longitudinal direction of the elbow 20 refers to the direction in which the length of the elbow 20 extends. When the elbow 20 is placed on the stomach, the outer side of the elbow 20 along the length direction will be attached to the stomach wall to ensure the shape of the residual stomach is proper, and because the connecting line between any two sound holes 21 is not parallel to the length direction of the elbow 20, at least one sound hole 21 is not covered by the stomach wall when the elbow 20 is attached to the stomach wall, so that the elbow 20 can still make a sound to indicate whether the resection is in place.

In some embodiments, the outer diameter of the pull tube 10 is less than the outer diameter of the elbow 20. When the elbow 20 is placed in the stomach, the traction tube 10 is placed in the gastric tube 40, obviously, the gastric tube 40 is narrower than the stomach, and in order to reduce the resistance when the traction tube 10 is placed in the gastric tube 40, the outer diameter of the traction tube 10 is smaller than that of the elbow 20, so that the elbow 20 can move in the gastric tube 40 to drive and adjust the position of the elbow 20 in the stomach. Furthermore, the elbow 20 is not communicated with the traction tube 10, so that the volume change of the traction tube 10 can be prevented from causing the volume change of the elbow 20, and the accuracy of sound production is prevented from being influenced. In this embodiment, the gastrectomy guide further includes a gastric tube 40, and the outer diameter of the traction tube is smaller than the inner diameter of the gastric tube 40, so that the traction tube is movable within the gastric tube 40. In addition, the inner wall of the gastric tube 40 can be coated with lubricant, which is convenient for separating the elbow 20 and the gastric tube 40 and can also reduce the friction resistance of the traction tube moving in the gastric tube 40. Accordingly, the outer walls of the traction tube 10 and the elbow 20 are smooth, so that the traction tube is easy to move in the gastric tube 40 and does not hurt the human body.

The sounding part comprises a sheet 32, a sounding post 31 and a mounting component, wherein the sheet 32 and the sounding post 31 are fixed in the sound hole 21 through the mounting component, the side surface of the sounding post 31 is provided with an opening, the sheet 32 covers the opening, and a circulation channel 35 is formed between the sounding post 31 and the sheet 32. In this embodiment, the opening of the sound column 31 is a plane opening, the upper portion of the sheet 32 is connected with the edge of the opening but not fixedly connected, and the cross section of the flow channel is semicircular. As the volume of the elbow 20 changes, gas flows inside and outside the elbow 20 through the sound holes 21, specifically, the gas flows rapidly through the flow channel 35, and the vibrating sheet 32 causes the sheet 32 to rapidly beat the sound column 31 to generate sound, thereby indicating the volume change of the elbow 20 during the operation. Further, a preset included angle is formed between the flow direction of the flow channel 35 and the axial direction of the sound hole 21, the preset included angle is greater than or equal to 0 degrees and smaller than 45 degrees, and it is ensured that most of the gas entering the sound hole 21 can flow through the flow channel 35 to push the sheet 32 to move. In this embodiment, the flow direction of the flow channel 35 is parallel to the axial direction of the sound hole 21, and most of the gas entering the sound hole 21 can directly flow into the flow channel 35, so that the gas in the flow channel 35 has a faster flow rate, the sheet 32 can be vibrated more vigorously to generate sound, and the sound generating component can prompt the volume change of the elbow 20 more sensitively.

The installation component includes barrel 33, is equipped with fixing base 34 on the inner wall of barrel 33, and the bottom of thin slice 32 and the bottom of sound production post 31 are all installed on fixing base 34. The cylinder 33 is embedded in the inner wall of the sound hole 21, and the fixing seat 34 does not block the passage opening of the flow passage 35 while fixing the sheet 32 and the sound column 31. In this application, the end of the sound component close to the inside of the elbow 20 is the bottom end, whereas the end close to the outside of the elbow 20 is the top end. Further, the bottom end of barrel 33 is equipped with and blocks piece 36, blocks that piece 36 can be the grid, when not blockking that gas flows into phonate hole 21, also can prevent parts such as flake 32 and phonation post 31 from falling into return bend 20, influences operation safety.

In some embodiments, referring to fig. 5-6, a first end of the elbow 20 is attached to the pull tube 10 and a second end of the elbow 20 is provided with a bulbous portion 22. The ball 22 is designed to be secured to the duodenal bulb to better locate the elbow 20 and avoid displacement of the elbow 20 during surgery resulting in an offset resection location. Further, the elbow 20 and the spherical portion 22 are connected by a connecting section 23, and the outer peripheral side of the connecting section 23 is recessed in the elbow 20 and the spherical portion 22. The connecting section 23 is narrow, and specifically, the outer diameter of the connecting section 23 is smaller than the outer diameter of the elbow 20 and smaller than the outer diameter of the spherical portion 22. The connecting section 23 is fixed at the pyloric sphincter, and because the pyloric sphincter is narrower than the stomach and the duodenal bulbar part, the connecting section 23 which is recessed in the elbow 20 and the spherical part 22 can just adapt to the shape of the pyloric sphincter, thereby avoiding the influence on the normal operation caused by the continuous extrusion of the pyloric sphincter by the connecting section 23. Alternatively, the bulbous portion 22 and the connecting section 23 are both rubber members, soft and easily deformable, so that both the bulbous portion 22 and the connecting section 23 can be pressed into the gastric tube 40 without damaging the pyloric sphincter after placement and positioning. Further, the connecting segment 23 is not connected to the elbow 20, thereby avoiding volume changes of the elbow 20 caused by the pyloric sphincter squeezing the connecting segment 23.

The utility model discloses a use as follows:

the traction tube 10, the elbow 20, the connecting section 23 and the spherical part 22 are compressed into the gastric tube 40, then the gastric tube 40 is inserted into the stomach until the end part of the gastric tube 40 is inserted into the duodenal bulb, at the moment, the traction tube 10 and the gastric tube 40 are pulled to enable the spherical part 22, the connecting section 23 and the elbow 20 to be gradually separated from the gastric tube 40, the spherical part 22 is arranged in the duodenal bulb, the connecting section 23 is arranged in the pyloric sphincter, and the elbow 20 is attached to the inner wall of the stomach. When the bending and extending direction of the elbow 20 is cut off, the operator should adjust the cutting position immediately until the elbow 20 does not make a sound when the elbow 20 makes a sound. After the resection is completed, the traction tube 10 and the gastric tube 40 are pulled, so that the elbow 20, the connecting section 23 and the spherical part 22 are pressed into the gastric tube 40 again, and the gastric tube 40 is separated from the human body integrally.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
