Description

Technical Field

[0001] The utility model relates to medical equipment, in particular to a gastric support drainage tube with a balloon for weight loss metabolic gastric volume reduction surgery. Background Art

[0002] Gastric volume reduction surgery mainly includes sleeve gastrectomy, which is to use laparoscope to vertically cut out the greater curvature of the stomach, so that the stomach forms a small stomach pouch of about 150cc, which can hold about 4-5 ounces of food. Its advantage is that it does not require the insertion of foreign objects in the body, and the weight loss effect of the surgery is significant.

[0003] The gastric support drainage tube is used during gastric volume reduction surgery. The inflated support balloon can assist in confirming the gastric volume reduction cutting position and calibrating the gastric capacity that needs to be retained, thereby achieving pressurization and decompression of gastric tissue, injection of drugs, calibration, and measurement under the support state.

[0004] A drainage hole is opened at the front end of the gastric support drainage tube. During the gastric volume reduction surgery, gastric fluid can be drained out of the body through negative pressure to achieve the purpose of gastrointestinal decompression. The problem with the current gastric support drainage tube is that each drainage hole is directly opened at the front end of the outer tube, and the drainage hole is a negative pressure hole. During operation, the negative pressure will make the drainage tube and the gastrectomy wound close together, thereby affecting the wound, and the negative pressure is likely to cause the wound to bleed again.

[0005] For example, in the prior patent, CN208926372U - an auxiliary device for measuring excess gastric cavity for weight loss surgery, in this patent, the drainage holes are opened on the drainage tube, and the drainage holes 6 are staggered on the tube body. During the negative pressure drainage process of the auxiliary device, the drainage holes far away from the balloon position are easy to be adsorbed with the gastric cavity tissue.

A plurality of external drainage holes are provided at the front end of the outer tube, and each external drainage hole is connected to the drainage cavity.

[0010] The inner tube is inserted into the drainage cavity from the rear end of the outer tube, a plurality of inner drainage holes are provided at the front end of the inner tube, and the rear end of the inner tube is suitable for connecting to a negative pressure device so that a negative pressure is formed in the inner tube; the inner tube sucks out the gastric fluid entering the drainage cavity through the inner drainage holes at the front end.

[0011] Furthermore, external drainage holes are provided on the outer tubes at the front and rear sides of the balloon.

[0012] Furthermore, inner drainage holes are provided at the front end and the circumferential side wall of the inner tube.

[0013] Furthermore, the rear end of the inner tube is connected to a negative pressure connector, and the negative pressure connector includes three openings, which are respectively located at a first interface, a second interface, and a third interface.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The present application provides a balloon-supported gastric drainage tube for weight loss metabolic gastric volume reduction surgery, which is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0029] In order to solve the technical problem that the wound is easily bleed again due to negative pressure when the drainage hole of the gastric support drainage tube is drained under negative pressure during gastric volume reduction surgery in the prior art, an embodiment of the present application provides a gastric support drainage tube with a balloon for weight loss metabolic gastric volume reduction surgery. The following is a detailed description.

[0030] like Figures 1 to 3 As shown, a gastric support drainage tube with a balloon for weight loss metabolic gastric volume reduction surgery comprises an outer tube 2, wherein the outer tube 2 is provided with double cavities, namely, an air cavity and a drainage cavity, a balloon 1 is provided at the front end of the outer tube 2, the balloon 1 is communicated with the front end of the air cavity, and the rear end of the air cavity is connected to a one-way valve 22; a plurality of external drainage holes 21 are provided at the front end of the outer tube 2, and each external drainage hole 21 is communicated with the drainage cavity;

[0031] The inner tube 3 is inserted into the drainage cavity from the rear end of the outer tube 2. A plurality of inner drainage holes 31 are provided at the front end of the inner tube 3. The rear end of the inner tube 3 is suitable for connecting to a negative pressure device so that the inner tube 3 forms a negative pressure. The inner tube 3 sucks out the gastric fluid entering the drainage cavity through the inner drainage holes 31 at the front end.

[0032] In this embodiment, a guide head is formed at the front end of the outer tube 2 for guiding the outer tube 2 to be inserted into the stomach cavity.

[0033] In this embodiment, the air cavity may also be replaced by a separate hose.

[0034] In this embodiment, the inflation and deflation of the balloon 1 can be controlled by the one-way valve 22, and the balloon 1 can be inflated by air or by physiological saline.

[0035] Specifically, as an optional implementation in this embodiment, Figure 2 As shown, external drainage holes 21 are provided on the outer tubes 2 at the front and rear sides of the balloon 1.

[0036] In this embodiment, two external drainage holes 21 are opened on the outer tube 2 at the front end of the balloon 1, and the two external drainage holes 21 are radially symmetrically distributed on the outer tube 2. Eight external drainage holes 21 are opened on the outer tube 2 at the rear end of the balloon 1, and the eight external drainage holes 21 are radially symmetrically distributed on the outer tube 2.

[0037] Specifically, as an optional implementation in this embodiment, Figure 3 As shown, the front end and the circumferential side wall of the inner tube 3 are provided with inner drainage holes 31 .

[0038] Specifically, as an optional implementation in this embodiment, Figure 3 As shown, the rear end of the inner tube 3 is connected to the negative pressure connector 4, and the negative pressure connector 4 includes three openings, which are respectively located at a first interface 41, a second interface 42 and a third interface 43. The first interface 41 is sealed and connected to the inner tube 3, the second interface is suitable for connecting to a negative pressure device, and the third interface 43 is a negative pressure regulating port;

[0039] The negative pressure connector 4 is connected to a plug 44 for closing the third interface 43 .

[0040] When the plug 44 closes the third interface 43, the pressure generated by the negative pressure device directly acts on each inner drainage hole 31. When the plug 44 is opened, air enters the third interface 43, and the pressure of each inner drainage hole 31 decreases.

[0041] Specifically, as an optional implementation in this embodiment, Figure 1 Figure 2 As shown, a developing line 23 is arranged on the outer tube 2 , and the developing line 23 is axially arranged on the outer tube 2 .

[0042] In this embodiment, the developing line 23 can be used for radiographic positioning and post-operative monitoring of the catheter placement position.

[0043] Specifically, as an optional implementation in this embodiment, the outer tube 2 and the inner tube 3 are made of PVC or TPU material.

[0044] The method of using the utility model of the gastric support drainage tube with balloon for weight loss metabolic gastric volume reduction surgery:

[0045] Under laparoscopy, the support drainage tube is extended into the gastric cavity, and then the balloon 1 is injected with gas or liquid through the one-way valve 22, so that the balloon 1 supports the gastric cavity. Next, the gastric volume reduction surgery is started, and the gastric support tube resection line is resected and sutured. Gastric fluid enters the drainage cavity of the outer tube 2 through the external drainage hole 21, and the negative pressure device sucks the inner tube 3, so that the inner tube 3 is under negative pressure. The inner tube 3 absorbs the gastric fluid in the drainage cavity through each inner drainage hole 31. Since the negative pressure of the inner tube 3 first acts on the drainage cavity of the outer tube 2, and then acts on the gastric cavity through the drainage cavity, the pressure on the outer drainage hole 21 becomes smaller. When the outer tube 2 is in close contact with the gastric resection wound, the negative pressure has no effect on the gastric resection wound, avoiding the possibility of the wound bleeding again due to negative pressure.
