Description

Technical Field

[0001] This invention relates to the field of pressure-measuring support tube technology, and more specifically, to an adjustable pressure-measuring support tube for sleeve gastrectomy. Background Technology

[0002] Sleeve gastrectomy, also known as vertical sleeve gastrectomy, is a weight loss surgery. Its main purpose is to help patients lose weight by reducing the capacity of the stomach and restricting food intake. In vertical sleeve gastrectomy, doctors remove most of the stomach, leaving a narrow, sleeve-shaped pouch. This sleeve-shaped stomach usually occupies about 75-80% of the original stomach. The capacity of this small, pouch-like stomach restricts the patient's food intake, thereby promoting weight loss.

[0003] When removing the stomach via sleeve gastrectomy, a gastric tube is inserted into the patient's stomach cavity to support the stomach. The excess stomach is removed by cutting and closing along the outer wall of the gastric tube with a cutting and closing device. The remaining stomach then wraps around the gastric tube to form a banana-shaped stomach. However, the existing gastric tubes have a simple structure, cannot be adjusted in diameter for patients with different physical conditions, are inconvenient to use, and cannot monitor the gastric pressure of the remaining stomach. Summary of the Invention

[0004] To overcome the above deficiencies, the present invention provides an adjustable pressure-measuring support tube for sleeve gastrectomy that overcomes or at least partially solves the above technical problems.

[0005] This invention is implemented as follows: This invention provides an adjustable pressure-measuring support tube for sleeve gastrectomy, comprising a support tube, an adjustment component, a suction component, and a leak-detection component. A fixing plate is fixedly mounted at one end of the support tube, and a conical head is mounted at the other end. The adjustment component includes… A capsule, symmetrically mounted on the surface of a support tube, is used to adjust the diameter of the support tube; The first strip-shaped airbag is symmetrically installed in the inner cavity of the airbag to support the airbag body, and one end of each of the first strip-shaped airbags is connected to a first air injection tube. The second strip-shaped airbag is symmetrically installed in the inner cavity of the airbag, and one end of each of the second strip-shaped airbags is connected to a second air injection tube. The third strip-shaped airbag is symmetrically installed in the inner cavity of the airbag. One end of each of the third strip-shaped airbags is connected to a third air injection tube. One end of the first air injection tube, the second air injection tube and the third air injection tube is equipped with a barometer for monitoring the pressure of the airbag.

[0006] In a preferred embodiment, the perimeter of the support tube is 30-36F.

[0007] In a preferred embodiment, the distance between the two cysts is 15-32 cm.

[0008] By incorporating an adjustable component, the support tube is inserted into the patient's stomach during the procedure to provide support. An external air pump connects to the first, second, and third air inflation tubes, allowing for the inflation of the first, second, and third balloons respectively. Each balloon inflates to a different diameter at a specific pressure, enabling the selection of which layer to inflate based on the patient's individual needs, thus adjusting the diameter of the support tube for ease of use. The remaining stomach contents compress the balloons on the surface of the support tube, thereby compressing the first, second, and third balloons inside. The gastric pressure of the remaining stomach contents can then be measured using a barometer.

[0009] In a preferred embodiment, the liquid aspiration assembly includes a liquid aspiration hole, a liquid aspiration chamber, and a liquid aspiration tube. The liquid aspiration hole is symmetrically opened on the side wall of the support tube, and the liquid aspiration chamber is opened in the inner cavity of the support tube for aspirating gastric fluid. The inner cavity of the liquid aspiration chamber is connected to the liquid aspiration tube.

[0010] In a preferred embodiment, a connector is installed at the other end of the suction tube.

[0011] By incorporating a suction component, an external suction pump can be connected to the connector to drain gastric fluid and air through the suction port, preventing fluid from obstructing the surgeon's view and reducing the difficulty of the procedure. Furthermore, gastric fluid may contain gastric acid and other digestive juices, which could cause infection or other complications if they enter the surgical area; suctioning the fluid helps reduce the risk of contamination in the surgical area. Additionally, gastric fluid can increase internal pressure, which may affect gastric tissue during surgery; suctioning the fluid can alleviate this internal pressure and help maintain normal physiological function.

[0012] In a preferred embodiment, the leak detection assembly includes a solvent chamber, an elastic membrane, and a one-way permeation membrane. The solvent chamber is located inside the support tube, and the elastic membrane is disposed within the solvent chamber and covers the outer wall of the support tube.

[0013] In a preferred embodiment, the one-way permeation membrane is installed on the outer wall of the solvent chamber to seal the solvent chamber.

[0014] In a preferred embodiment, the solvent chamber is filled with toluidine blue solution for monitoring blood leakage.

[0015] In a preferred embodiment, the inner wall of the support tube has several through holes.

[0016] In a preferred embodiment, the unidirectional permeation membrane is unidirectionally permeable towards the solvent chamber.

[0017] By setting up a leak detection component, a visual probe is inserted into the support tube to observe the surgical situation in real time. The support tube can be moved to the vicinity of the sutured stomach. If the stomach suture is incomplete at this time, blood will seep out at the gap, increasing the pressure near the gap. The blood will pass through the one-way permeable membrane into the solvent chamber and react with the toluidine blue solution, causing the blue color of the toluidine blue solution to gradually turn green. This color change can help doctors find the bleeding point more easily during surgery. In addition, the elastic membrane undergoes elastic deformation into the through hole under pressure, causing the inner wall of the support tube to bulge, making it easier to detect.

[0018] The adjustable pressure-measuring support tube for sleeve gastrectomy provided by this invention has the following beneficial effects: By incorporating an adjustable component, the support tube is inserted into the patient's stomach during the procedure to provide support. An external air pump connects to the first, second, and third air inflation tubes, allowing for the inflation of the first, second, and third balloons respectively. Each balloon inflates to a different diameter at a specific pressure, enabling the selection of which layer to inflate based on the patient's individual needs, thus adjusting the diameter of the support tube for ease of use. The remaining stomach contents compress the balloons on the surface of the support tube, thereby compressing the first, second, and third balloons inside. The gastric pressure of the remaining stomach contents can then be measured using a barometer.

[0019] 2. By incorporating a suction component, an external suction pump can be connected to the connector to drain gastric fluid and air through the suction port, preventing fluid from obstructing the surgeon's view and reducing the difficulty of the procedure. Furthermore, gastric fluid may contain gastric acid and other digestive juices; if these fluids enter the surgical area, they may cause infection or other complications. Suctioning the fluid helps reduce the risk of contamination in the surgical area. Additionally, gastric fluid may increase internal pressure, which could affect gastric tissue during surgery. Suctioning the fluid can alleviate this internal pressure and help maintain normal physiological function.

[0020] 3. By setting up a leak detection component, a visual probe is inserted into the support tube to observe the surgical situation in real time. The support tube can be moved to the vicinity of the sutured stomach. If the stomach suture is incomplete at this time, blood will seep out at the gap, increasing the pressure near the gap. The blood passes through the one-way permeable membrane into the solvent chamber and reacts with the toluidine blue solution, causing the blue of the toluidine blue solution to gradually turn green. This color change can help doctors find the bleeding point more easily during surgery. In addition, the elastic membrane undergoes elastic deformation into the through hole under pressure, causing the inner wall of the support tube to bulge, making it easier to detect.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figures 1-8As shown, the present invention provides a technical solution: an adjustable pressure-measuring support tube for sleeve gastrectomy, comprising a support tube 1, an adjustment component 4, a suction component 5, and a leak detection component 6. The circumference of the support tube 1 is 30-36F. During the operation, the support tube 1 is inserted into the patient's stomach to provide support. The excess stomach is removed by cutting and closing along the outer wall of the support tube 1 with a cutting and closing device. Finally, the remaining stomach just wraps around the support tube 1 to form a banana-shaped stomach. A fixing plate 2 is fixedly installed at one end of the support tube 1 to facilitate the operation of the support tube 1. A conical head 3 is installed at the other end of the support tube 1 to facilitate the insertion of the support tube 1 into the patient's stomach. The adjustment component 4 includes a bladder 401, a first strip-shaped air bladder 402, a second strip-shaped air bladder 403, and a third strip-shaped air bladder 404. The bladders 401 are symmetrically installed on the surface of the support tube 1 to adjust the diameter of the support tube 1 to accommodate different patients and avoid adverse consequences such as narrowing of the passage. The distance between the two bladders 401 is 15-32cm.

[0024] Reference Figures 1-4 As shown, in a preferred embodiment, first strip-shaped airbags 402 are symmetrically installed inside the bladder body 401 to support the bladder body 401. One end of each of the first strip-shaped airbags 402 is connected to a first inflation tube 405 for inflating the first strip-shaped airbags 402. Second strip-shaped airbags 403 are symmetrically installed inside the bladder body 401, and one end of each of the second strip-shaped airbags 403 is connected to a second inflation tube 406. Third strip-shaped airbags 404 are symmetrically installed inside the bladder body 401, and one end of each of the third strip-shaped airbags 404 is connected to a third inflation tube 406. 07. In use, the first air injection tube 405, the second air injection tube 406, and the third air injection tube 407 can be connected to an external air pump to inflate the first strip-shaped airbag 402, the second strip-shaped airbag 403, and the third strip-shaped airbag 404 respectively. The diameter of each airbag when inflated to a specific pressure is different. The diameter is largest when the first strip-shaped airbag 402, the second strip-shaped airbag 403, and the third strip-shaped airbag 404 are inflated simultaneously. This allows for selection of which layer to inflate according to the different physical needs of patients, thereby adjusting the diameter of the support tube 1 for convenient use.

[0025] Reference Figures 1-4 As shown, in a preferred embodiment, a barometer 408 is installed at one end of the first air inlet tube 405, the second air inlet tube 406, and the third air inlet tube 407 to monitor the pressure of the bladder 401. The remaining stomach compresses the bladder 401 on the surface of the support tube 1, thereby compressing the first strip-shaped air bladder 402, the second strip-shaped air bladder 403, and the third strip-shaped air bladder 404 inside the bladder 401. The gastric pressure of the remaining stomach can be measured by the barometer 408.

[0026] In a preferred embodiment, during the procedure, the support tube 1 is inserted into the patient's stomach to provide support. An external air pump can be connected to the first air injection tube 405, the second air injection tube 406, and the third air injection tube 407, respectively, to inflate the first strip-shaped airbag 402, the second strip-shaped airbag 403, and the third strip-shaped airbag 404. Each airbag has a different inflated diameter when inflated to a specific pressure. The first strip-shaped airbag 402, the second strip-shaped airbag 403, and the third strip-shaped airbag 404 have the largest diameter when inflated simultaneously. This allows for selection of which layer to inflate according to the patient's physical condition, thus adjusting the diameter of the support tube 1 for ease of use. The remaining stomach contents compress the bladder 401 on the surface of the support tube 1, thereby compressing the first strip-shaped airbag 402, the second strip-shaped airbag 403, and the third strip-shaped airbag 404 inside the bladder 401. The gastric pressure of the remaining stomach contents can be measured using a barometer 408.

[0027] Reference Figures 1-6 As shown, in a preferred embodiment, the liquid suction assembly 5 includes a liquid suction hole 501, a liquid suction chamber 502, and a liquid suction tube 503. The liquid suction hole 501 is symmetrically opened on the side wall of the support tube 1, and the liquid suction chamber 502 is opened in the inner cavity of the support tube 1 for suctioning gastric fluid. The inner cavity of the liquid suction chamber 502 is connected to the liquid suction tube 503, and a connector 504 is installed at the other end of the liquid suction tube 503.

[0028] In a preferred embodiment, during surgery, a suction pump can be connected to the external end of connector 504 to drain gastric fluid and air through suction hole 501, preventing fluid from obstructing the doctor's view and reducing the difficulty of the surgery. Furthermore, gastric fluid may contain gastric acid and other digestive juices, which may cause infection or other complications if they enter the surgical area. Aspirating the fluid helps reduce the risk of contamination in the surgical area. In addition, gastric fluid may increase the internal pressure of the stomach, which may have a certain impact on the gastric tissue during surgery. By aspirating the fluid, this internal pressure can be relieved, which helps maintain a normal physiological state.

[0029] Reference Figures 1-8 As shown, in a preferred embodiment, the leak detection component 6 includes a solvent chamber 601, an elastic membrane 603, and a one-way permeation membrane 604. The solvent chamber 601 is opened in the inner cavity of the support tube 1 and is used to fill toluidine blue solution. A plurality of through holes 602 are opened in the inner wall of the support tube 1. The elastic membrane 603 is disposed in the solvent chamber 601 and covers the outer wall of the support tube 1.

[0030] Reference Figures 1-8As shown, in a preferred embodiment, a one-way permeation membrane 604 is installed on the outer wall of the solvent chamber 601 to seal the solvent chamber 601. The solvent chamber 601 is filled with toluidine blue solution for monitoring blood leakage. One of the main components of blood is hemoglobin, which has a certain reducing property. When blood comes into contact with toluidine blue, the toluidine blue undergoes an oxidation-reduction reaction with the reducing substances in the blood, causing the color of the toluidine blue to change. The blue of the toluidine blue gradually turns into green. This color change can help doctors more easily identify and locate bleeding points during surgery. The one-way permeation membrane 604 is unidirectionally permeable to the solvent chamber 601.

[0031] In a preferred embodiment, during surgery, a visual probe is inserted into the support tube 1 to observe the surgical situation in real time. The support tube 1 can be moved to the vicinity of the sutured stomach. If the stomach suture is incomplete at this time, blood will seep out at the gap, increasing the pressure near the gap. The blood passes through the one-way permeation membrane 604 into the solvent chamber 601 and reacts with the toluidine blue solution, causing the blue color of the toluidine blue solution to gradually change to green. This color change can help doctors more easily find bleeding points during surgery. Furthermore, under pressure, the elastic membrane 603 undergoes elastic deformation into the through hole 602, causing the inner wall of the support tube 1 to form a protrusion, making it easier to detect.

[0032] Specifically, the working process or principle of the adjustable pressure-measuring support tube used in sleeve gastrectomy is as follows: During the operation, the support tube 1 is inserted into the patient's stomach to provide support. An external air pump connects to the first air injection tube 405, the second air injection tube 406, and the third air injection tube 407, respectively, to inflate the first strip-shaped airbag 402, the second strip-shaped airbag 403, and the third strip-shaped airbag 404. Each airbag inflates to a different diameter at a specific pressure. The first strip-shaped airbag 402... 2. The second strip-shaped air bladder 403 and the third strip-shaped air bladder 404 are inflated to their maximum diameter at the same time. This allows for selection of which layer to inflate based on the patient's physical condition, thus adjusting the diameter of the support tube 1 for ease of use. The remaining stomach contents compress the bladder 401 on the surface of the support tube 1, thereby compressing the first strip-shaped air bladder 402, the second strip-shaped air bladder 403, and the third strip-shaped air bladder 404 inside the bladder 401. The gastric pressure of the remaining stomach contents can be measured by the barometer 408.

[0033] During surgery, a suction pump can be connected to the external end of connector 504 to drain the gastric fluid and air through suction port 501, preventing the fluid from obstructing the doctor's view and reducing the difficulty of the surgery. In addition, gastric fluid may contain gastric acid and other digestive juices, which may cause infection or other complications if they enter the surgical area. Aspirating the fluid helps reduce the risk of contamination in the surgical area. Furthermore, gastric fluid may increase the internal pressure of the stomach, which may have a certain impact on the gastric tissue during the operation. By aspirating the fluid, this internal pressure can be relieved, which helps maintain a normal physiological state.

[0034] The visual probe is inserted into the support tube 1 to observe the surgical situation in real time. The support tube 1 can be moved to the vicinity of the sutured stomach. If the stomach suture is incomplete at this time, blood will seep out at the gap, which will increase the pressure near the gap. The blood will pass through the one-way permeation membrane 604 into the solvent chamber 601 and react with the toluidine blue solution, causing the blue of the toluidine blue solution to gradually turn green. This color change can help doctors find the bleeding point more easily during the operation. Under the action of pressure, the elastic membrane 603 undergoes elastic deformation in the through hole 602, causing the inner wall of the support tube 1 to form a protrusion, which is easier to find.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0036] It should be noted that the barometer 408 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail here.
