Recyclable hepatic portal occlusion device under laparoscope

Abstract

The invention discloses a recoverable hepatic portal occlusion device under laparoscope, including a main tube. Limiting plates which can be lifted and rotated are installed inside the main tube, a bottom tube is installed on the lower side of a base, and a rotatable rotating inner shell is arranged at the position corresponding to the limiting plates inside the bottom tube, the upper end of the rotating inner shell is fixedly connected with a limiting column connected to the limiting plates, the bottom end of the rotating inner shell is provided with a rotating closed structure which can rotates with the rotation of the rotating inner shell, the surface of the main tube is connected with a lifting knob by screw threads, the bottom end of the lifting knob is connected with a knob base by bearings, and the lower side of the knob base is provided with a clamping structure; and the bottom tube for fixing a hepatic portal occlusion belt and the main tube can be detached, when the bottom tube is used to fix the hepatic portal occlusion belt, the bottom tube can be directly placed in the patient's body, the operation is simple and convenient, and an intelligent alarm clock can also timing the blocking and relaxing time to the hepatic portal, so that medical staff can be reminded to prevent liver damage caused by long-time blocking at the right time.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a recoverable hepatic portal blocking device under laparoscopy. Background technique [0002] Portal hepatic occlusion is an effective way to control bleeding during liver surgery. However, how to quickly and effectively block and release the hilum of the liver during laparoscopic anatomical liver resection has always been a difficult problem for hepatobiliary surgeons. There are many kinds of current operation methods. The common one is to pass a thin red urinary catheter through the sheath behind the first hepatic hilum, tie a knot around the hepatoduodenal ligament by Pringle method, and clamp a Hemlock at the node. To block the hilum, cut the Hemlock and remove the clip when releasing the hilum. The existing hepatic portal blockage scheme is relatively complicated to operate, takes a long time, and requires an assistant to be skilled in laparoscopic operation. If the knot o...

Problems solved by technology

Although the existing portal blocking scheme can block and release the portal at any time as in the open state, the tube must have sufficient length from the portal to the outside, and the tube suspended between the portal and the abdominal wall is often Affect the surgical operation of the surgeon and assistants, increasing the risk of surgery
