Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a hepatic blood flow occlusion band for practical hepatectomy. Background Technique

[0002] For liver tumors, surgical operation is the primary and main treatment method. However, due to the rich blood supply of the liver, compared with surgeries on other organs, the control of intraoperative bleeding has always been a difficult problem. The hepatic blood flow occlusion technique is considered the best method for controlling bleeding during hepatectomy. Currently, the hepatic occlusion methods are divided into three categories: inflow hepatic blood occlusion method, total hepatic blood occlusion method, and hepatic blood flow occlusion by liver lifting method. The inflow hepatic blood occlusion method is the most widely used hepatic blood flow occlusion technique at present. It is simple to operate and the occlusion effect is practical and reliable. That is, the inflow hepatic blood of the whole liver is temporarily occluded at normal temperature by occluding the hepatoduodenal ligament, thereby reducing intraoperative liver bleeding. Clinically, a Fogarty occlusion forceps or a special vascular occlusion band is generally used to implement the occlusion.

[0003] However, with the development of surgical techniques in recent years, there is no significant difference between the indications for laparoscopic liver surgery and open surgery. The above-mentioned instruments have poor flexibility for intracavitary occlusion of the first hepatic hilar blood flow under laparoscopy. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: A hepatic blood flow occlusion band for practical hepatectomy, including a band body. One end of the band body is fixedly connected with a fixed tube ring, and a convex ring is fixedly connected to the inner side of the band body. A plurality of convex rings are symmetrically arranged, and the convex rings are linearly arranged. Limiting spheres are fixedly connected to the inner sides of the convex rings.

[0009] Preferably, a raised strip is fixedly connected to the outside of the fixed pipe ring. A plurality of the raised strips are symmetrically arranged, and the surface of the raised strip is rough.

[0010] Preferably, a tail end convex block is fixedly connected to one end of the belt body. The tail end convex block is of an arc structure.

[0011] Preferably, the diameter of one end of the belt body is larger than that of the other end.

Be careful not to take out the fixed pipe ring together. The assistant holds the head end of the belt body with the curved separating forceps, and the surgeon or the assistant holds the grasping part of the fixed pipe ring with an instrument. After lifting and pulling to adjust the belt body to a proper position, the hepatic inflow occlusion can be completed. When releasing the blood flow occlusion, the surgeon or the assistant respectively holds the grasping part of the fixed pipe ring and the belt body, and loosens the sleeve structure to release the blood flow occlusion. After the operation, the belt body is taken out through the trocar, that is, one end of the belt body is inserted into the inside of the fixed pipe ring, and the belt body is pulled.
