Referring to fig. 1-7, a cardiac gastrectomy-preserving guide device includes an extraction tube 10 and a support balloon 20. Wherein, the traction tube 10 is a flexible structure and can be arranged in the stomach tube 40. Specifically, traction tube 10 is flexible solid construction, and traction tube 10 is arranged in stomach tube 40 and can slide each other, and further scribbles the emollient between stomach tube 40 and traction tube 10, easily slides.

The supporting bag 20 is connected with the traction tube 10, the supporting bag 20 is of a hollow elastic shell-shaped structure, so that the supporting bag 20 has a compression state and a release state, the supporting bag 20 is placed in the stomach tube 40 in the compression state, the supporting bag 20 is released freely after being separated from the stomach tube 40, and then is attached to the stomach wall in the release state, so that the shape of the residual stomach is determined. Wherein the support bladder 20 is a rubber material member.

It can be understood that, during the operation, as shown in fig. 4, the supporting bag 20 is compressed in the gastric tube 40 and passes through the cardia together, at this time, the traction tube 10 is inserted into the stomach from the outside, and in cooperation with the gastric tube 40 being pulled out from the outside, the supporting bag 20 is separated from the gastric tube 40 in the stomach and returns to the release state, as shown in fig. 5, and is fixed at the cardia exactly. In addition, the length of the traction tube 10 is greater than that of the gastric tube 40, and when the support sac 20 is positioned in the stomach, the traction tube 10 is still partially outside the body and is left outside the gastric tube 40 for controlling the support sac 20 in the stomach outside the body.

When the supporting bag 20 is in a release state, the outer surface of the supporting bag 20 is a smooth surface, the outer surface of the supporting bag 20 is in a shape of a remnant stomach which can be exactly matched with the jejunum on the side, but can not be necrotic due to insufficient blood supply, and the supporting bag 20 has a small volume, is close to a pylorus and can not touch the tumor on the side of the small curve of the stomach. As shown in fig. 6, the stomach is pulled by the intestinal clamp 50 during the operation to make the supporting pouch 20 more fit with the stomach wall to ensure that the shape of the remnant stomach is the same as the shape of the supporting pouch 20. The support pouch 20 is relatively thin and does not place significant tension on the stomach wall and allow for inaccurate cutting.

In other embodiments, the support pouch 20 may be designed to retain the shape of the remnant stomach in the lateral lesser curvature of the stomach even when the pouch is released, and still be in a shape that will fit in the lateral jejunum without necrosis due to insufficient blood supply.

In this embodiment, the guiding device for cardiac gastrectomy further comprises a sounding component 30 disposed on the supporting bag 20, the supporting bag 20 is provided with an inner cavity for the sounding component 30 to be inserted, the sounding component 30 comprises a sounding post 33 and a thin sheet 32 for sensing airflow vibration, so that the thin sheet 32 can beat the sounding post 33 after the volume of the supporting bag 20 changes, thereby generating sound, and the sound hole 35 of the sounding component 30 is disposed at the outer end. Further, the sounding assembly 30 comprises a barrel 34 and a fixing rod 31 which are integrally arranged, the barrel is placed into the inner concave cavity, the sounding columns 33 and the thin sheet 32 are both installed on the fixing rod 31, and the sound holes 35 are located at the outer end of the barrel 34. Note that the sheet 32 is only a name of a component, and is understood as a vibrating piece, and the scope of the present invention is not limited by the thickness.

The sound producing assembly 30 has a small overall volume and can be compressed into the gastric tube 40 along with the support balloon 20. When the support cell 20 is in the released state, the volume of the support cell changes to generate a faster airflow, so that the plastic sheet 32 on the sound generating assembly 30 is vibrated to rapidly flap with the sound generating posts 33 to generate a sound for indicating the change in the volume of the support cell 20 to determine the cutting line of the stomach, and the sound generated by the sound generating assembly 30 is emitted from the sound hole 35. The physician determines the cutting line of the stomach with the sound-emitting assembly 30 just not emitting sound, and the remnant stomach is the shape of the support pouch 20.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
