Organ puncturing fixing device for endoscope operation

Abstract

The invention relates to the technical field of medical instruments, in particular to a fixing device for puncturing and supporting an organ during an endoscope operation. The fixing device comprises a tube, a traction needle, a traction wire and a supporting part. The traction needle, the traction wire and the supporting part are sleeved with the tube. The supporting part comprises a cover with an arc-shaped surface and at least a pair of supporting bodies of flat structures. The supporting bodies are symmetrically distributed on the cover. A through center hole is formed in the cover. One end of the traction wire is connected with the supporting bodies, and the other end of the traction wire extends outside the cover through the center hole from the cover and is connected with the traction needle. The organ puncturing fixing device for the endoscope operation has the advantages that the structure is simple, operation is convenient, the organ can be sufficiently drawn in the pneumoperitoneum state, and the portion needing the operation can be effectively exposed so that injuries of the operation to the human body can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a fixing device for puncturing and supporting organs during endoscopic surgery. Background technique [0002] Laparoscopic surgery has been widely used clinically due to its small overall trauma and quick recovery. [0003] Taking laparoscopic subtotal gastrectomy as an example, the human stomach is located behind the liver, along the cardia, gastric body, and pylorus, and about 50% of the gastric tissue on the side of the lesser curvature of the stomach is covered by the liver. As the liver is one of the most important organs of the human body, it receives dual blood supply from the hepatic artery and the portal vein at the same time, so its blood circulation system has a complex structure, and there are rich connections and interactions between various blood vessels, and the blood supply is rich. During the operation, a certain space is usually left between the liv...

AI Technical Summary

Problems solved by technology

This exposure method has the following obvious defects: 1. When using forceps or a retractable baffle to stir up the liver, it is easy to damage the liver tissue due to the difficulty in controlling the force and instability; 2. The assistant must continue to occupy a poking hole to Provoking the liver, you can’t free your hands, and you can’t effectively cooperate with the surgeon to perform the operation; 3. Due to the size limit of the abdominal wall poking hole, the size and shape of the forceps or the retractable baffle entering the abdominal cavity are not ideal, and cannot reach satisfactory exposure

The defects of the part of the liver supporter in this invention are: 1. Poor feasibility in actual operation. In single-port laparoscopic surgery, there is only one access hole in the abdominal wall, and the instruments that must be placed in this hole include mirror body, main operation Forceps and auxiliary operating forceps, the retractor device of the present invention is placed in the limited space, and the access holes are continuously occupied during the entire operation process, which will seriously affect the progress of the operation; 2. The assistant needs to adjust and monitor the supporting part in real time, 3. The parts are cumbersome and cumbersome. In laparoscopic spleen surgery or other laparoscopic surgery, the retraction of organs or viscera is a small part of the operation and should not take up too much time. Surgical process and operator's energy, and the retractor device in the present invention has many parts, and device type is big, and in actual operation, needs real-time monitoring and position adjustment, wastes time and energy; More, the more serious the mutual interference, it is easy to cause the risk of blocking the operation and forming a blind area of ​​operation, and the cost is high, causing unnecessary economic burden to the patient
