Nowadays, patients with stomach diseases are increasing year by year, the number of gastrectomy operations is also increasing year by year, and in addition, the prevalence of obesity-reducing wind makes more obese patients achieve weight reduction through partial gastrectomy operations. However, in the minimally invasive partial gastrectomy before improvement, the size of the resected part cannot be well controlled when the stomach of the part is resected, and the damage to the patient caused by the gastrectomy cannot be better avoided.

Referring to fig. 1, the present application provides a gastric surgery assisting device 100, which is applied to a gastric 101 resection operation, and includes: a guide part 10, the guide part 10 having a through hole 11; and the positioning part 30 is connected to the end part of the guiding part 10, and encloses with the end part of the guiding part 10 to form a cavity 31, the cavity 31 is communicated with the through hole 11, the positioning part 30 has elasticity, and when the cavity 31 is filled with fluid, the positioning part 30 deforms and expands and abuts against the inner wall of the stomach 101.

The gastric surgery assisting apparatus 100 of the present application embodiment of the present application includes: a guide part 10, the guide part 10 having a through hole 11; and the positioning part 30 is connected to the end of the guiding part 10, and encloses with the end of the guiding part 10 to form a cavity 31, the cavity 31 is communicated with the through hole 11, the positioning part 30 has elasticity, and when the cavity 31 is filled with fluid, the positioning part 30 deforms and expands and abuts against the inner wall of the stomach 101 (as shown in fig. 2). When the operation of excising the stomach 101 is performed, the end of the positioning part 30 of the auxiliary device 100 for the operation on the stomach 101 according to the embodiment of the present invention is inserted into the mouth, passes through the esophagus and enters the stomach 101, the amount of the fluid to be filled into the through hole 11 and the cavity 31 is determined according to the size of the stomach 101 and the ratio of the portion to be excised, the amount of the fluid to be filled into the cavity 31 is determined, so that the positioning part 30 is deformed and expanded and abuts against the inner wall of the stomach 101, and then the excision on the stomach 101 is performed from the outside of the stomach 101. When the area of the stomach 101 needing to be resected is smaller, more fluid is filled into the cavity 31, and when the area of the stomach 101 needing to be resected is larger, less fluid is filled into the cavity 31, so that a doctor can more accurately resect the stomach 101, excessive resection can be better avoided, postoperative malnutrition of a postoperative patient is caused, the health of the patient is influenced, the resection is too little, secondary lesion is easy to occur, and the health of the patient is influenced. In addition, the expanded positioning part 30 is also beneficial to suturing after the stomach 101 is resected, so that the suturing speed is accelerated, the operation time is shortened, meanwhile, the sutured wound can be more fit with the original shape of the stomach 101, the postoperative recovery of a patient is facilitated, and the side effect of the operation on the patient is reduced.

Alternatively, the fluid may be a liquid or a gas, and preferably, the fluid is a liquid, which is not easily compressed, so that it is more convenient to calculate the amount of liquid to be filled, and more accurately grasp the area of the stomach 101 to be cut.

In some embodiments, the guiding portion 10 and the positioning portion 30 can be formed separately and then fixedly connected together, and in other embodiments, the guiding portion 10 and the positioning portion 30 are an integral structure, which can be formed by two-material blow molding, injection molding, etc.

In some embodiments, the guide 10 is a tube body enclosing the through hole 11, and the through hole 11 is used for fluid to pass through. When in use, the guiding part 10 is partially positioned in the body and the part is positioned outside the body, and fluid is injected into the guiding part 10 to enter the positioning part 30, so that the positioning part 30 is expanded to abut against the inner wall of the stomach 101.

In some embodiments, the material of the guiding portion 10 is one or more of silicone, thermoplastic polyurethane, polyethylene terephthalate, modified polyethylene terephthalate, and ethylene vinyl acetate. In other words, the guide part 10 may be made of one or more of silicone, thermoplastic polyurethane, polyethylene terephthalate, modified polyethylene terephthalate, and ethylene vinyl acetate. These substances have good biocompatibility, low cost and simple preparation process.

In some embodiments, the guide portion 10 HAs a shore hardness of 30HA to 80 HA; specifically, the shore hardness of the guide portion 10 may be, but is not limited to, 30HA, 35HA, 40HA, 45HA, 50HA, 55HA, 60HA, 65HA, 70HA, 75HA, 80HA, and the like. When the shore hardness of the guiding portion 10 is less than 30HA, it is difficult to pass through the esophagus to enter the stomach 101 in use, and when the shore hardness of the guiding portion 10 is more than 80HA, it is easy to damage the esophagus or the stomach 101 carelessly when passing through the esophagus or the stomach 101.

Further, the shore hardness of the guiding portion 10 is 40HA to 60 HA; specifically, the shore hardness of the guide portion 10 may be, but is not limited to, 40HA, 42HA, 44HA, 45HA, 46HA, 48HA, 50HA, 52HA, 55HA, 58HA, 60HA, and the like. When the shore hardness of the guiding portion 10 is in this range, the guiding portion can well penetrate through the esophagus and enter the stomach 101 without damaging the esophagus and the stomach 101.

Optionally, the shore hardness of the guiding portion 10 is greater than that of the positioning portion 30, the shore hardness of the guiding portion 10 is greater, so that the guiding portion can easily pass through the esophagus, and the shore hardness of the positioning portion 30 is small, so that the positioning portion 30 can be better inflated.

Referring to fig. 1 and fig. 2, optionally, in some embodiments, the positioning portion 30 includes a first end 33 and a second end 35 that are oppositely disposed, the first end 33 and the second end 35 are respectively connected to the guiding portion 10, and a distance between the first end 33 and the second end 35 is 10cm to 35 cm. Specifically, the distance between the first end 33 and the second end 35 may be, but is not limited to, 10cm, 12cm, 15cm, 18cm, 20cm, 23cm, 25cm, 28cm, 30cm, 32cm, 35cm, and the like. When the distance from the first end 33 to the second end 35 of the positioning portion 30 is within this range, the size of the stomach 101 can be better adapted, which is beneficial for faster and more accurate cutting and suturing, and furthermore, the positioning portion 30 with different sizes can be referred to according to the sizes of the stomach 101 of different ages.

Optionally, the distance between the first end 33 and the second end 35 is 27cm to 32 cm. Specifically, the distance between the first end 33 and the second end 35 may be, but is not limited to, 27cm, 28cm, 29cm, 30cm, 31cm, 32cm, 33cm, 34cm, 35cm, and the like. This makes the positioning part 30 more suitable for the size of the stomach 101 of an adult.

In some embodiments, the positioning portion 30 has a hemispherical shape or a semi-ellipsoidal shape, and an outer periphery of the positioning portion 30 is connected to one end of the guiding portion 10 to form the cavity 31. The shape of the positioning part 30 may be other regular or irregular shapes, and the present application is not particularly limited. When the positioning part 30 is in a semi-ellipsoidal shape, it will fit the stomach 101 after expansion, so that the operation of removing the stomach 101 can be faster and more accurate.

In some embodiments, when the shape of the detent 30 is a semi-ellipsoid shape having one major radius and two minor radii, the two minor radii of the semi-ellipsoid shape are equal, and the ratio of the minor radius to the major radius is 1:3 to 2: 3.

In some embodiments, the guide portion 10 and the positioning portion 30 are made of biocompatible materials.

In some embodiments, the material of the positioning portion 30 is one or more of silicone, thermoplastic polyurethane, polyethylene terephthalate, modified polyethylene terephthalate, and ethylene vinyl acetate. In other words, the positioning part 30 may be made of one or more of silicone, thermoplastic polyurethane, polyethylene terephthalate, modified polyethylene terephthalate, and ethylene vinyl acetate. These substances have good biocompatibility, low cost and simple preparation process.

Alternatively, the positioning portion 30 and the guide portion 10 may be made of the same or different materials, and the present application is not particularly limited.

In some embodiments, the shore hardness of the positioning portion 30 is 15HA to 40 HA. Specifically, the shore hardness of the positioning portion 30 may be, but is not limited to, 15HA, 18HA, 20HA, 22HA, 25HA, 26HA, 28HA, 30HA, 35HA, 38HA, 40HA, and the like. When the shore hardness of the positioning portion 30 is less than 15HA, the elasticity is too large, the supporting force of the positioning portion 30 is insufficient, which is not favorable for performing the excision operation and quickly suturing, and when the shore hardness of the positioning portion 30 is more than 30HA, the hardness is too large, which is not easy to blow up or expand.

Referring to fig. 3, in some embodiments, the gastric surgery assisting device 100 of the embodiment of the present application further includes a camera 50, where the camera 50 is disposed on the guiding portion 10 and located in the cavity 31 for obtaining an image of a target object (e.g., a stomach) so as to be able to accurately observe the condition of the target object (e.g., the stomach), and measure the specific size of the expanded positioning portion 30 during surgery so as to more accurately calculate the size of a portion to be resected, thereby improving the accuracy of stomach resection.
