Description

Technical Field

[0001] The present invention relates to the technical field of blood flow control devices, and in particular to an intelligent, digitalized liver blood flow control device. Background Art

[0002] China is a country with a high incidence of liver cancer, accounting for the third largest number of newly diagnosed tumors in China. Surgical resection is the most important radical treatment for liver cancer, especially laparoscopic liver resection, which is a safe and minimally invasive surgical method and has been widely used in the surgical treatment of primary hepatocellular carcinoma. Due to the complex anatomy of the liver vascular system, rich in blood sinusoids, abundant blood flow, and high tissue fragility, liver surgery is prone to bleeding and is extremely difficult. Bleeding control is the main problem faced by liver surgeons. At present, the blood flow into the liver is mainly controlled by completely blocking the first hepatic portal during surgery, and there is no unified instrument and device. The commonly used The device is a catheter, glove edge and other equipment, which is used to wrap around the first portal blood vessel and tighten it to block it, so as to control the blood flow of the hepatic artery and portal vein that supply blood to the liver. After a period of time, the blocked catheter or glove edge is loosened to restore the blood supply to the liver. When in use, blocking and opening need to be performed alternately. When blocking, the liver is ischemic, and the liver resection operation is completed at this time. The liver is not prone to bleeding during the process. When opening, the liver restores blood supply to ensure liver function. The commonly used blocking time and opening time method is: blocking for 10-20 minutes and opening for 5 minutes. There are problems caused by this situation.

[0003] At present, there is no intelligent, digital, and adjustable liver blood flow control device in clinical practice. During the surgical operation, a blood flow controller is pre-installed at the first portal of the liver. The controller can measure the blood flow of the hepatic artery and portal vein through ultrasound, and can record real-time pressure data according to the pressure feedback device. The extracorporeal equipment can intelligently set the time of blocking and opening.

[0004] Existing liver blood flow control operations require blood flow control of the patient's first portal vein. Traditional blood flow control methods use catheters, gloves and other equipment to wrap the first portal vein and tighten it to block it. However, after blocking the blood vessel in this way, it is generally not easy to restore the blood vessel, making it difficult to meet the surgical conditions of blocking for 10-20 minutes and opening for 5 minutes in the operating room.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-5, an intelligent, digital liver blood flow control device, comprising a central operating table 1, a connecting line 3 is fixedly installed on the top of the central operating table 1, and the end of the connecting line 3 away from the central operating table 1 is fixedly connected to a controller 2, and a blocking rope 4 is fixedly installed on the top of the controller 2, and an adjusting mechanism is arranged inside the controller 2, and one end of the blocking rope 4 is rotatably connected to a connecting screw head 5, and the adjusting mechanism is connected to the blocking rope 4 through the connecting screw head 5, and the controller 2 and the central operating table 1 are electrically connected; in the process of performing surgery on patients with liver cancer, doctors usually only perform surgery in a blocked state, and the surgical blocking of blood vessels requires blocking for 10-20 minutes and opening for 5 minutes. Under such surgical conditions, the blood flow of the blood vessels is blocked by traditional methods, and the first portal blood vessel is wrapped and tightened to block it using equipment such as a urinary catheter and a glove edge, so as to control the hepatic artery and portal vein that supply blood to the liver. The blood flow of the pulse is reduced, and the blocked catheter or glove edge is released after a period of time to restore the blood supply to the liver. This method requires a certain amount of operation time during the operation, resulting in a prolonged operation. Therefore, the present invention blocks the blood vessel through the blocking rope 4, and controls the regulating mechanism inside the controller 2 through the central operating table 1, so that the blocking rope 4 can block for 10-20 minutes and open for 5 minutes according to the requirements of the operation, and the blocking rope 4 itself has a certain elasticity. After the regulating mechanism relaxes the traction of the blocking rope 4, the blocking rope 4 will reset itself, so that the blood vessel blocking is ended. In addition, since liver cancer patients are usually accompanied by hepatitis, liver fibrosis or cirrhosis, and the liver's tolerance to ischemia is different with different degrees of cirrhosis, the same blocking and opening time cannot achieve individualized and precise control of liver blood flow. The tightening state of the blocking rope 4 is infinitely adjusted by the regulating mechanism to meet the blocking requirements of different patients.

[0026] As a preferred technical solution of this embodiment, the adjustment mechanism includes a connecting stud 6, which is slidably installed on the top of the controller 2. The inside of the controller 2 is rotatably connected with a first gear 8, a second gear 9 is provided on one side of the first gear 8, and the second gear 9 is rotatably installed inside the controller 2. The first gear 8 is meshed with the second gear 9. The bottom of the connecting stud 6 is fixedly connected with an adjusting screw 7, and the adjusting screw 7 is threadedly connected to the first gear 8. The bottom of the second gear 9 is fixedly installed with a micro motor 10, and the micro motor 10 is fixedly installed inside the controller 2; when using the blocking rope 4 When blocking the blood flow in the blood vessel, the connecting screw head 5 at one end of the blocking rope 4 is threadedly connected with the connecting stud 6 on the top of the controller 2, and then the micro motor 10 is turned on. The second gear 9 is driven to rotate by the micro motor 10, so that the first gear 8 meshing with the second gear 9 rotates. The rotation of the first gear 8 causes the adjusting screw 7 threadedly connected to the first gear 8 to drive the connecting stud 6 to continuously shrink into the controller 2, so that the blocking rope 4 is tightened on the blood vessel more and more, thereby achieving the purpose of blocking the blood flow inside the blood vessel. According to the different falling distances of the connecting stud 6, the blocking effect on the blood vessel will also be different, thereby adapting to various patients with different symptoms.

[0027] As a preferred technical solution of this embodiment, the controller 2 is made of silicone material; during the operation, when the blood vessels are blocked, the controller 2 is placed in the patient's body, and the controller 2 is set to silicone material to protect the patient's trachea, avoiding the use of other materials to stimulate the patient's organs and cause discomfort to the patient.

[0028] As the preferred technical solution of this embodiment, a pressure sensor 11 is provided on the blocking rope 4, and an ultrasonic detection probe 12 is fixedly installed on the side wall of the controller 2, and the ultrasonic detection probe 12 and the pressure sensor 11 are both electrically connected to the central operating table 1; the blood vessels during the operation are monitored by the pressure sensor 11 and the ultrasonic detection probe 12. Existing liver cancer patients are usually accompanied by hepatitis, liver fibrosis or cirrhosis, and the liver's tolerance to ischemia varies with the degree of cirrhosis. Using the same blocking and opening time, it is impossible to achieve individualized and precise control of liver blood flow. During the operation, the blood flow data detected by the ultrasonic detection probe 12 and the pressure data monitored by the pressure sensor 11 are recorded to record the blood flow of the hepatic artery and the portal vein during the blocking process. An intelligent blocking model is created based on a large amount of data when the hepatic artery and portal vein blood flow are blocked, which not only ensures blood supply to the liver to maintain liver function, but also ensures that bleeding can be effectively controlled during the operation, and finally achieves an intelligent continuous blocking state. The operation can continue without the need to complete the alternation of all blocking and opening operations.

[0029] As a preferred technical solution of this embodiment, a display screen 13 is fixedly installed on the top of the central operating console 1, and a control panel 14 is fixedly installed on the other side of the top of the central operating console 1. The display screen 13 and the control panel 14 are electrically connected to the central operating console 1; the central operating console 1 is controlled by the control panel 14, and the display screen 13 displays the data monitored by the pressure sensor 11 and the ultrasonic detection probe 12 on the controller 2, and a large amount of blood flow data can be exported and statistically analyzed.

[0030] As a preferred technical solution of this embodiment, support columns 15 are fixedly installed at the four corners of the bottom of the central operating table 1; the central operating table 1 is supported by the support columns 15 at the four corners to increase the stability of the device.

[0031] refer to Figure 6 As the preferred technical solution of this embodiment, the output ends of the pressure sensor 11 and the ultrasonic detection probe 12 are electrically connected to the input end of the central operating console 1, and the output end of the central operating console 1 is electrically connected to the display screen 13 and the input end of the controller 2 respectively; when in use, the central operating console 1 issues a signal instruction to the controller, so that the controller drives the blocking rope 4 to block the blood flow of the patient's blood vessels. At the same time, the ultrasonic detection probe 12 and the pressure sensor 11 arranged on the controller and the blocking rope 4 measure the blood flow data after blocking, transmit these data signals to the display screen 13 for display, and transmit them to the display screen 13 for display. The data on the display screen 13 are analyzed and statistically calculated to obtain the appropriate blood vessel blocking strength for the patient. The blocking strength of the blocking rope 4 is controlled by a controller using the central console. The blood flow of the hepatic artery and portal vein during the blocking process is recorded through data feedback and statistical analysis between the various components. An intelligent blocking model is created based on a large amount of data when the hepatic artery and portal vein blood flow are blocked. This not only ensures blood supply to the liver to maintain liver function, but also ensures that bleeding can be effectively controlled during the surgical operation. Ultimately, the operation can be continued in an intelligent continuous blocking state without the need to complete all the alternating blocking and opening operations.

[0032] The specific working process of the present invention is as follows: during the liver cancer surgery on the patient, the controller 2 is placed at the position of the blood vessel that needs to be blocked, the blood vessel is wrapped with a blocking tube rope, and then the connecting screw head 5 at one end of the blocking rope 4 is connected to the connecting stud 6, and the blocking rope 4 is driven to tighten through the adjustment mechanism to block and tighten the blood vessel. During the blocking process, the ultrasonic detection probe 12 and the pressure sensor 11 will also be used to record data such as the blood flow of the hepatic artery and portal vein during the blocking process. An intelligent blocking model is created based on a large amount of data when the hepatic artery and portal vein blood flow are blocked, which not only ensures the blood supply to the liver to maintain liver function, but also ensures that bleeding can be effectively controlled during the surgical operation, and finally achieves an intelligent continuous blocking state. The operation can continue without the need to complete all the alternating blocking and opening operations.

[0033] By controlling the micro motor 10, the position of the connecting stud 6 inside the controller 2 is changed, so that the degree of tightening of the blocking rope 4 on the blood vessel is continuously deepened and relaxed. The micro motor 10 is controlled to achieve stepless regulation. The blocking time and the opening time set by controlling the micro motor 10 are automatically alternated, which saves the doctor's operation process and greatly reduces the operation time.

[0034] Since liver cancer patients usually have hepatitis, liver fibrosis or cirrhosis, and the liver's tolerance to ischemia varies with the degree of cirrhosis, the same blocking and opening time cannot achieve individualized and precise control of liver blood flow. Therefore, the micro motor 10 can be used to adjust the tightness of the blocking rope 4 to cope with patients with different symptoms.
