Visceral organ suspension device for endoscopic surgery

Abstract

The invention provides a visceral organ suspension device for endoscopic surgery, which structurally comprises a basic suspension belt formed by arranging elastic edgings at two ends of a flexible belt-shaped film along the width direction and used for being arranged along the long diameter direction of a visceral organ so as to suspend a visceral organ main body; an additional hanging belt is composed of one or more flexible belt-shaped thin films; one end of each flexible belt-shaped film is pivoted with the basic suspension belt, and the other end of each flexible belt-shaped film is free and is provided with an elastic edge strip along the width direction; the additional hanging belt is used for hanging other parts of the viscera beyond the hanging range of the basic hanging belt; preformed holes are formed in the two ends of the basic hanging belt and the free end of each additional hanging belt and used for being connected with an in-vitro fixing facility after a traction line penetrates through the preformed holes. The device provided by the invention can continuously and stably pull large tissues such as liver and lung lobes, efficiently and clearly reveal the operation view field, slightly presses the pulled tissues, cannot cause damage to the tissues or organs, can be repeatedly used in the same operation, and is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an organ suspension device for endoscopic surgery. Background technique [0002] Endoscopic surgery, including laparoscopy and thoracoscopy, has the advantages of less trauma and low risk, and has been increasingly used in clinical practice. Examples include laparoscopic gastric and duodenal surgery, thoracoscopic esophagectomy or lobectomy, laparoscopic rectal cancer resection, and more. In order to make this type of minimally invasive endoscopic surgery go smoothly, it is often necessary to suspend nearby organs or tissues that block the line of sight and hinder the operation, so as to fully reveal the surgical field of view. [0003] There are densely distributed important blood vessels, bile ducts, and lymphatic vessels around the stomach and duodenum. When performing laparoscopic total gastrectomy, partial gastrectomy, or duodenal-related operations, the surgeon must alwa...

AI Technical Summary

Problems solved by technology

The assistant can add a special puncture hole in the abdominal wall, and use fan-shaped forceps to pull the left lobe of the liver forward to the right to expose the stomach and duodenum. However, this method requires an additional puncture hole and occupies one arm of the assistant. steadily revealed

It is also possible to suture the liver tissue with silk thread, and pass both ends of the silk thread out of the abdominal cavity to suspend and fix the liver on the anterior abdominal wall. Although this method can save one puncture hole, long-term pulling of the silk thread will damage the liver parenchyma and its tissues. The internal blood vessels and bile ducts play a cutting role, causing liver damage

Commercial liver retractors can also be used, but this device not only requires a special puncture hole, but also is expensive and inconvenient to operate. In addition, the metal retractor compresses the liver for a long time may cause liver subcapsular hematoma, cause additional liver damage

[0005] At present, several patents have designed liver suspension devices. Patent document CN203436352U discloses a laparoscopic liver suspension device, but its stability is poor, and only a small amount of liver tissue is pulled, and the exposed field of view is not good.

Patent document CN204744271U discloses a liver suspension device for laparoscopic surgery, but it needs to separate the coronary ligament around the liver, which will cause damage to blood vessels and lymphatic vessels around it, and it only suspends the middle position of the left lobe of the liver, so that The left free surface of the left outer lobe of the liver is still in a drooping state, showing poorly

Patent document CN108567456A discloses a liver suspension device for laparoscopic surgery, but it also needs to separate the ligaments around the liver, which will cause damage to the surrounding blood vessels and lymphatic vessels, and the "cross" method of suspending the liver is poor, and The free end of the intersection may damage the liver. In addition, the "cross" shaped support is only fixed by a single silk thread at both ends, and the stability is poor

[0006] Therefore, the existing liver suspension apparatus cannot suspend and fix the liver in a safer, more effective and more convenient manner.
