Abstract

The invention discloses a visual visceral canal flow quantitative monitoring and control device. The device comprises a handle; a middle rod which is connected with the handle; aworking rod, wherein the two ends of the working rod are the near end and the far end respectively, the near end is connected with the middle rod, the working rod can be switched between the rod-shaped working rod and the lantern ring-shaped working rod, the area defined by bending of the lantern ring-shaped working rod is an in-ring space, the working rod surrounds a pipe body of the visceral organ through the in-ring space when the working rod is in the lantern ring shape, and the working rod is constructed to have the tendency of deforming towards the lantern ring shape; a traction rope, which drives the working rod to deform towards the rod when being pulled towards the handle; a transmission mechanism which is connected with the traction rope; an ultrasonic detector which is arranged at the far end of the working rod; and a display which is electrically connected with the ultrasonic detector so as to display the detection result of the ultrasonic detector. According to the monitoring and control device, the flow of the visceral organ tube body is conveniently and quantitatively adjusted, the controllability of an operation is conveniently improved, and the life safety of a patient is improved.

Description

technical field [0001] The invention relates to the technical field of medical treatment and medical equipment, in particular to a visualized quantitative monitoring and control device for organ tube flow. Background technique [0002] With the development of minimally invasive surgical techniques and instruments, more and more laparoscopic operations are used in liver operations represented by partial hepatectomy. The liver is an organ with a very rich blood supply. Hemorrhage during liver-related operations will hinder the operation and pose a threat to the safety of the operation. In order to be able to perform surgery under a clear view, the hepatic hilum is often blocked during surgery to block the blood flow into the liver, so as to reduce surgical bleeding. Unfortunately, there is still a lack of devices that can effectively control blood flow into the liver in laparoscopic surgery. Existing methods for controlling blood flow into the liver rely on the surgeon's exp...
