Problems solved by technology

At present, surgeons use a thick gastric tube for LSG surgery. After the operation, the gastric tube must be removed, and then an ordinary gastric tube with a thin tube is inserted for postoperative drainage. It is difficult to insert a thick gastric tube before surgery, and it is easy to cause mucosal damage.
After the operation, the thick tube needs to be pulled out, and then a thinner ordinary gastric tube should be reinserted, which will cause troublesome operation and easily cause mucosal damage
Although there are also reports of some similar special instruments at present, such as Chinese patent application CN107773289 A, this patent still cannot solve the above problems

Embodiment 1

[0027] see Figure 1-3 , a gastric tube for laparoscopic partial gastrectomy, comprising a gastric tube body 1 with a length of about 90 cm, the outer diameter and inner diameter of the gastric tube body 1 are respectively 0.53 cm and 0.49 cm, and the diameter of the gastric tube body 1 is about 0.53cm (consistent with the diameter of F16 ordinary gastric tube); that is figure 1 The length of middle a to d is about 90cm; the head end of the gastric tube body 1 is provided with a connecting part 2, which is used to connect a drainage bag or a syringe, etc.;

[0028] An elastic part 3 is arranged on the gastric tube body 1, and the length of the elastic part 3 is about 20 cm, that is, figure 1 The length from b to c is about 20cm, figure 1 Middle x to b are non-elastic parts with a length of about 55cm; the starting end of the elastic part 3 is about 60cm away from the head end of the stomach tube body, that is figure 1 The length of middle a to b is about 60cm; the elastic p...

Embodiment 2

[0041] refer to Figure 4-6 , the present embodiment is similar to the embodiment 1 except that the shape of the elastic part 3 and the number of branch pipes 5 are different from the embodiment 1:

[0042] The elastic part 3 of this embodiment is still made of thinner elastic rubber as in the first embodiment, but the elastic part 3 of this embodiment does not surround the gastric tube body 1 for a whole week, but is on the outer periphery of the gastric tube body 1 Two independent elastic parts 3 are set; the two elastic parts 3 are arranged symmetrically on the outer periphery of the gastric tube body 1, correspondingly, the number of branch tubes 5 is also two, that is, independent inflation or liquid filling, and the two elastic parts 3 simultaneously After filling, Figure 5 The distance between g and h is also 1.0-1.2cm;

[0043] The operation mode of the product in this embodiment is also similar to the operation of the product in embodiment 1, except that the two el...

Abstract

The invention discloses a gastric tube for laparoscopic partial gastrectomy, and belongs to the technical field of medical instruments. The gastric tube comprises a gastric tube body (1), an elastic part (3) is arranged on the gastric tube body (1), the elastic part (3) is positioned at the periphery of the gastric tube body (1) and a separate cavity (4) is arranged between the elastic part and the gastric tube body (1), a branch tube (5) is also arranged on the gastric tube body (1), the branch tube (5) is communicated with the separate cavity (4), and a one-way valve (6) is arranged on the branch tube (5). When the inner part of the elastic part is not inflated with gas or liquid does not expand, the shape of the gastric tube is similar to that of common thin gastric tubes, and the gastric tube is convenient and safe to insert before operation, does not damage mucosa, and does not need to be taken out after operation; and the gastric tube also plays a supporting tube and a guiding role in the LSG operation, so that excessive cutting of the stomach wall is avoided, the narrow stomach cavity is avoided, the trauma and the pain of a patient are greatly reduced, and the experience feeling of the LSG is obviously improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gastric tube for laparoscopic partial gastrectomy. Background technique [0002] In recent years, weight loss is not only about beauty, but more importantly, the treatment of some diseases such as type 2 diabetes can also be controlled and treated through weight loss. With the continuous improvement of bariatric surgery methods and the maturity of laparoscopic surgery technology, this surgery will be accepted by more and more patients due to its advantages of safety, effectiveness and minimal invasiveness. Nowadays, people's requirements for health and quality of life are increasing day by day, and their understanding of surgical weight loss is more profound. Surgical treatment of obesity has been accepted by more people. [0003] In terms of surgical procedures, after repeated practice by surgeons, laparoscopic sleeve gastrectomy (LSG) has been proven to be a weight-r...
