Description

Technical Field

[0001] The invention relates to the technical field of colorectal cancer surgical equipment, and in particular to a post-anastomosis leak detection and air-inflation device during colorectal cancer surgery. Background Art

[0002] Anastomotic leakage is a serious complication after colorectal cancer surgery, which significantly affects the patient's perioperative recovery and quality of life. After the intestinal anastomosis is recanalized, the surgeon often needs to check the integrity of the intestinal anastomosis. Due to the limited pelvic operating space and uneven tissue anastomosis, it is impossible to visually see whether there are potential small defects and leaks.

[0003] Currently, there is no universal device that can detect whether the anastomosis is intact and leak-free during surgery. Some hospitals or doctors use intestinal water injection during surgery to briefly judge the quality of the anastomosis, but it is unable to achieve accurate positioning and quantitative standards. In addition, during the detection process, the intestine is relatively lubricated, and the intestinal diameters and anastomotic positions of patients of different body sizes are different, which may lead to slippage and leakage, affecting the detection effect and making the overall operation less convenient.

[0004] Therefore, there is an urgent need for a leak detection and inflation device after anastomosis during colorectal cancer surgery to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a leak detection and inflation device after anastomosis during colorectal cancer surgery, which has a simple structure and is easy to use. It can effectively locate the intestinal diameter and anastomotic position of patients of various body types and facilitate quantitative control of intestinal pressure.

[0008] In some embodiments of the present invention, the above-mentioned blocking bag is a filling air bag, and the two blocking bags are connected by a connecting tube; the blocking bag is provided with an inflation tube connected to the second inflation device.

[0009] In some embodiments of the present invention, a filling tube is disposed in the intestinal catheter, and the filling tube and the liquid storage tube are connected. A sealing plate is disposed in the liquid storage tube, and a control rod is connected to one end of the sealing plate.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example:

[0024] Please refer to Figure 1-2 The present embodiment provides a post-anastomosis leak detection and inflation device for colorectal cancer surgery, which includes an intestinal catheter 1, on which two blocking bags 2 are arranged at intervals; an air outlet pipe 6 is arranged in the intestinal catheter 1, one end of the air outlet pipe 6 passes through the intestinal catheter 1 and is located between the two blocking bags 2, and the other end of the air outlet pipe 6 is connected to a first inflation device.

[0025] Currently, there is no universal device that can detect whether the anastomosis is complete and leak-free during surgery. Some hospitals or doctors use intestinal water injection during surgery to briefly judge the quality of the anastomosis, but it cannot achieve accurate positioning and quantitative standards. The present invention sets two blocking bags 2 on the intestinal catheter 1, so that medical staff can send the intestinal catheter 1 into the anastomotic position in the patient's intestine, block the two positions of the front and back intestines through the two blocking bags 2, and then inflate the inside through the outlet pipe 6. Through the colored gas seepage, the scope and specific position of the anastomotic leakage can be directly observed.

[0026] In some embodiments of the present invention, the blocking bag 2 is a filling air bag, and the two blocking bags 2 are connected through a connecting tube 5; the blocking bag 2 is provided with an inflation tube 7 connected to the second inflation device 14. The blocking bag 2 is a filling air bag, and is connected to the second inflation device 14 through the inflation tube 7, so that medical staff can expand the filling air bag through the inflation tube 7, thereby effectively blocking the patient's intestine.

[0027] In some embodiments of the present invention, a filling tube 4 is provided in the intestinal catheter 1, and the filling tube 4 and the liquid storage tube 8 are provided in the liquid storage tube 8. A sealing plate 9 is provided in the liquid storage tube 8, and one end of the sealing plate 9 is connected to a control rod 10. The filling tube 4 provided in the intestinal catheter 1 allows medical staff to move the sealing plate 9 through the control rod 10, so that the liquid in the liquid storage tube 8 is filled into the filling tube 4, so that the intestinal catheter 1 can be supported by the filling tube 4, so that the hardness of the intestinal catheter 1 is improved, and it can better enter the patient's intestines.

[0028] In some embodiments of the present invention, a pressure tube 11 is connected to the first inflation device and the second inflation device 14, a horizontal slide is provided in the pressure tube 11, a pressure plate 12 is provided on the horizontal slide, and a return spring 13 is provided on one side of the pressure plate 12. The return spring 13 in the pressure tube 11 cooperates with the pressure plate 12 to effectively provide medical staff with the filling pressure conditions in the patient's intestine and the blocking bag 2, which is convenient for medical staff to make judgments and treatments.

[0029] In some embodiments of the present invention, a depth scale is provided on the intestinal catheter 1, and a pressure scale is provided on the pressure tube 11. The depth scale provided on the intestinal catheter 1 can be used to observe the depth of the device and whether it has reached the predetermined position; the pressure scale can help medical staff determine the pressure of the gas in the intestine between the two blocking bags 2 and the liquid in the blocking bags 2 to facilitate adjustment.

[0030] In some embodiments of the present invention, a plurality of annular protrusions 3 are provided on the side of the blocking capsule 2, and the annular protrusions 3 are connected to the blocking capsule 2. The provision of the annular protrusions 3 can well block the patient's intestines.

[0031] In some embodiments of the present invention, the elastic stiffness coefficient of the blocking bag 2 is greater than that of the annular protrusion 3, so that the annular protrusion 3 is more easily deformed due to inflation to fit the patient's intestine, thereby facilitating blocking.

[0032] In summary, the embodiment of the present invention provides a post-anastomosis leak detection and inflation device for colorectal cancer surgery, which includes an intestinal catheter 1, on which two blocking bags 2 are arranged at intervals; an air outlet pipe 6 is arranged in the intestinal catheter 1, one end of the air outlet pipe 6 passes through the intestinal catheter 1 and is located between the two blocking bags 2, and the other end of the air outlet pipe 6 is connected to a first inflation device. By arranging two blocking bags 2 on the intestinal catheter 1, the present invention allows medical staff to deliver the intestinal catheter 1 to the anastomotic position in the patient's intestine, and after the two blocking bags 2 are used to block the two positions of the front and back intestines, the air outlet pipe 6 is used to inflate the inside, and the range and specific position of the anastomotic leakage can be directly observed through the colored gas seepage.
