[0002] The minimally invasive hepatectomy is a surgical operation method for removing liver tumor by using laparoscopic technique, specifically, through a small incision (generally the largest incision is 1cm, and the rest is 0.5cm) in the abdomen to enter the abdominal cavity, in the completely closed abdominal cavity, the laparoscope is used to separate the ligament around the liver, blood vessels and other related tissues, then various benign and malignant tumors in the liver are finely removed, finally the removed tissues are taken out of the body through the small incision. During the operation, the patient adopts the head-high and foot-low split-leg position. The doctor will make a 6~7cm long transverse incision as a hand-assisted incision about 1cm above the navel on the right abdomen, and make several small incisions at other positions to place the laparoscope and related instruments. Under the guidance of the laparoscope, the doctor can clearly see the situation in the abdominal cavity and carry out accurate operation. At present, when the liver resection or partial liver resection operation is performed under the laparoscope, the liver is located below the person, and due to the prolapse of the liver during the operation, the exposed area of the liver is often not clear, which increases the difficulty of the operation. When viral hepatitis, alcoholic hepatitis or infection with viral hepatitis occurs, the intraoperative field of view is more disturbed, the doctor needs to move the liver upward outside the body to fully expose the operation area and reduce the difficulty of the operation, or needs to push the liver upward during the resection operation to expose the operation area as needed, but once the external support lasts for a long time, the liver and the abdominal wall have adhesion, the support height of the external liver support device is fixed and cannot be adjusted at will, and the adhesion cannot be avoided, which cannot meet the use needs of safe and required control and guidance of the liver position during the operation, and there is no processing tool that can lift the liver at the corresponding position in the body and can perform directional micro-motion in the predetermined direction.

Specific implementation
[0022] The technical solutions in the specific implementation of the utility model will be described clearly and completely in combination with the drawings in the specific implementation of the utility model. Obviously, the described specific implementation is only a part of the specific implementation of the utility model, not all the specific implementation. Based on the specific implementation in the utility model, all other specific implementations obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0023] In the description of the utility model, it should be understood that the terms "upper", "middle", "outer", "inner" and the like indicate the orientation or positional relationship, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0024] Specific implementation one: in combination with Figures 1 to 5In this embodiment, the liver lifting device of the inflation control type comprises a puncture sleeve 1, a front catheter 2, a rear catheter 3, a main air bag 4, a secondary air bag 5, a first inflation tube 11 and a second inflation tube 12. The main air bag 4 and the secondary air bag 5 are arranged side by side. The puncture sleeve 1 is vertically arranged below the main air bag 4 and the secondary air bag 5. The upper end of the puncture sleeve 1 is connected with the bottom of the main air bag 4 and the bottom of the secondary air bag 5, respectively. The front catheter 2 and the rear catheter 3 are arranged in the puncture sleeve 1. One end of the front catheter 2 is connected with the main air bag 4, and the other end of the front catheter 2 is connected with the first inflation tube 11. One end of the rear catheter 3 is connected with the secondary air bag 5, and the other end of the rear catheter 3 is connected with the second inflation tube 12. The side of the main air bag 4 facing the secondary air bag 5 is sequentially provided with a first clamping part 6 and a first connecting part 7 from top to bottom. The side of the secondary air bag 5 facing the main air bag 4 is sequentially provided with a second clamping part 8 and a second connecting part from top to bottom. The first clamping part 6 and the second clamping part 8 form a clamping gap 13 cooperating with the liver 10. The first connecting part 7 is connected with the second connecting part. In this way, all liver surgeries cannot achieve a reasonable position of the liver. When performing liver resection, the surgical personnel need to move the liver to the right and upward. The existing technology cannot move in the correct direction. The moving direction of the device is consistent with the predetermined direction. When the front catheter 2 and the rear catheter 3 are inflated to the main air bag and the secondary air bag, the main air bag 4 and the secondary air bag 5 are inflated by inflation.
