Hepatic portal occlusion device

Abstract

The invention provides a hepatic portal occlusion device. The hepatic portal occlusion device comprises a water tube, a water bag, a water pump, a rod-like connecting rod and a controller. The water tube is provided with a closed first end and a closed second end, a containing space is defined by the water tube, and the containing space is decreased with the increase of liquid in the water tube and increased with the decrease of the liquid in the water tube. The water bag is used for storing a certain amount of liquid. The water pump is used for delivering liquid in the water bag to the water tube during hepatic portal occlusion and delivering the liquid in the water tube to the water bag during cancelling the hepatic portal occlusion. The rod-like connecting rod is detachably connected with the water pump. The controller is used for controlling the volume of the liquid in the water tube by controlling the water pump. According to the hepatic portal occlusion device, occlusion pressure can be adjusted during laparoscopic surgery, so that the selective occlusion is achieved, and liver injuries are reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a hepatic portal blocking device. Background technique [0002] Laparoscopic surgery is the use of laparoscopic lens inserted into the human abdominal cavity, and the use of laparoscopic instruments for surgery. Due to its minimally invasive, small scar and less pain, laparoscopic surgery is increasingly used in various fields of surgery, among which laparoscopic liver resection has gradually become an important way to treat benign and malignant liver diseases. However, the blood supply of the liver is very rich, and intraoperative bleeding is a major problem hindering laparoscopic liver resection. [0003] In traditional open hepatectomy, in order to reduce bleeding during hepatectomy, surgeons usually need to block the hepatoduodenal ligament to block the blood flow into the liver, that is, block the blood flow of the first hepatic portal. In the prior art, the hepatoduodenal...

AI Technical Summary

Problems solved by technology

In the process of cutting the liver under laparoscopy, because the hemostasis cannot be sutured quickly, it takes a long time, and more rounds of blocking are often required to complete the liver resection

In addition to the inconvenient operation of banding the porta hepatis with urinary catheters, more importantly, the force of banding is not easy to control, resulting in banding that is too tight or too loose, and the blocking effect is poor.
